Soups, stocks, and broths all need simmering to bring out flavors and cook the ingredients. Some recipes call for a long time to simmer these pots, especially if you are using a slow cooker.
You might be wondering if it’s possible to leave the soup to simmer for too long? I love cooking soups of all kinds, and I’ve learned a lot about what makes soup great.
Leaving a soup on a vigorous boil too long could ruin it due to overcooking the ingredients or reducing the liquid too much. However, soups can be lightly simmered for up to 8 hours to develop rich flavors. Ensure there is enough stock or water to prevent burning and add salt after the soup has simmered.
There’s a massive difference between a boil and a simmer, and the one thing you do not want to do is leave a soup to boil – especially for any considerable length of time. But soups benefit from long, slow cooking times at a low heat to help develop the flavors and soften ingredients like tough cuts of meat and dried peas. Some soups will cook faster, while others need a long simmer to get just right.
Can You Simmer Soup Too Long?
Soup will only be simmered for too long if the ingredients inside will overcook or the liquid runs low. Lean meat will become tough and soft vegetables will become mushy with too much simmering.
A simmer is when food is cooked at a temperature that stays below boiling point. Usually, the easiest way to do this is to bring your stock or soup to a boil, then reduce the heat until your soup stays at a constant temperature. Simmering is a great way to cook food to avoid the meat toughening or ingredients breaking into pieces or burning.
If you use a crockpot or electric cooker, you’ll be very familiar with foods like soups, chilis, or stews left to simmer while you’re at work. It’s a great way of prepping food and then leaving it to cook, ready to be eaten on your return.
You might be wondering if you can leave a soup to simmer for too long – certainly if the temperature is too high, you leave the pot for too long, and you don’t have enough stock liquid, you run the risk of burning your soup. But in many cases, soups can be left on a low simmer, such as the lowest setting on a crockpot, for about 8 hours without worry.
Use cuts suitable for slow cooking like chicken thighs, brisket, or pork shoulder, and add any soft vegetables near the end of the cooking process. Root vegetables and potatoes are more suitable for longer cooking.
How Long Can I Leave A Soup To Simmer?
How long you can leave soup simmer depends on the ingredients. Ingredients that need short cooking require about a 30-minute simmer while ingredients that can be slow-cooked can have 4-8 hours on a low simmer.
Some soups will not need much simmering at all if you have the stock ready, for example, a vegetable soup which might only need 30 minutes. Others might need much longer to soften ingredients.
If you’re new to making soups, you might be unsure about how long is too long. If you’re a beginner soup maker, my first piece of advice is to follow a trusted recipe exactly. As you become more experienced with making soups, you’ll be able to make your own recipes with a good idea of how long you’ll need to simmer them, depending on the ingredients.
Remember that the longer you leave a soup to simmer, the more liquid will evaporate (should you simmer with a lid?), resulting in your soup thickening. A thicker soup has a more concentrated flavor and is easier to burn. If you’re planning to simmer your soup for a long time, it’s good to keep an eye on the pot and check it occasionally to make sure it’s not burning.
What Happens If You Simmer Soup For Too Long?
If you simmer soup for too long meat will become tough or fall apart, vegetables will become mushy and disintegrate and the texture will be ruined. You might burn ingredients on the bottom and sides of the pan if you run out of liquid.
As you simmer your soup, water will evaporate, the ingredients will cook and break down, and your soup will begin to thicken. This slow simmer is an essential part of the cooking process as you don’t want tough, uncooked meat or hard lentils or peas in a soup.
If you simmer a soup for too long, you can end up with a soup that has become too thick and salty. If you know you’re going to be leaving a soup to simmer for a long time, make sure that there is enough liquid or stock to prevent the soup from thickening too much.
Add salt and seasonings nearer the end, as the reduced soup may be too salty if the salt is added while simmering. If added too early, pepper or dried herbs can overcook to add unwanted bitterness to your soup.
With most soups, the items that take longer to cook, like split peas or lentils, will be added first, followed by root veg. Quicker cooking vegetables like greens, or frozen peas, will only be added towards the end of the simmering time.
Simmer the stock or soup before adding quick-cooking ingredients (like frozen peas), which end up grey and unappetizing if overcooked.
Should You Simmer Soup With Lid On Or Off?
Simmering with the lid on will prevent evaporation and is best for longer cooking times or dishes that don’t need reducing. Simmering with the lid off will thicken the soup.
Leaving the lid on or off will depend on your situation and recipe. By leaving the cover off, the stock will evaporate faster, leaving you with a thicker, chunkier soup. This might be perfect for you, especially if you’re simmering your soup for a shorter period of time, and you do not have meat or dried ingredients that need long cooking times.
When leaving a lid off, because the water evaporates much faster, you need to watch your soup to ensure it doesn’t get too thick and the bottom sections burn.
If your soup seems too thin, you can take off the lid and raise the simmering heat a little to help thicken your soup. If you still have problems thickening then check out my post on how to thicken soup for some more great tips.
When simmering for longer periods, we want to keep the moisture in, so it’s more usual to keep the lid on. By keeping the soup covered, you retain the heat and moisture, which allows the temperature to remain constant – which is what you want when simmering a soup.
How Long Do You Let Stock Simmer?
Stock should be simmered for a minimum of 40 minutes and up to 3 hours. The longer it simmers, the tastier the stock becomes from the ingredients, so it is worth taking the extra time.
40 minutes really is a bare minimum and will give you a light-tasting stock unless you are using a lot of bones. At around 1.5 hours you will get a decent stock and around 3 hours the flavor will be best.
When cooking a homemade stock as the base for a soup, you’re trying to extract every bit of flavor from the bones, vegetables, and herbs you are using, so this long simmer time is appropriate.
You can roast chicken bones first to make a brown stock that is stronger and suited for use with meat dishes. White stock uses raw bones and is lighter in color and taste – good for soups.
Once your stock has simmered, you should be able to drain it off and throw away the remaining bones and vegetables. You can then use this stock as a base for making your soups. Many soups use chicken or beef stock as the liquid ingredient, creating a richer flavor rather than simply simmering the meat and vegetables in water.
When cooking a soup with a ready-made stock, the simmer time will be shorter. Again, it will depend on the other ingredients: a soup made with stewing beef may need a long slow simmer time of 6-8 hours, while a butternut and carrot soup will only need to be simmered until all the vegetables are tender – about 40 minutes.
Conclusion
The simmer time of your soup will depend on the ingredients and recipe, but most soups are not simmered for longer than a few hours or up to 8 in a slow cooker. Stocks will need to be simmered longer to break down the connecting tissue and bones to develop flavor. Avoid oversalting soup or leaving it to burn when simmering for long periods, which will ruin the soup.
Meat soups take longer to cook than veggie soups, but even so a very good veggie soup will have a better flavor after 1 hour of simmering than after 30 minutes, especially if you're cooking with root vegetables that take longer to cook thorough. What is this? You can't really overcook soup, or cook it for too long.
According the expert McGee consulted, soup or stock left to cool overnight, then reboiled for 10 minutes and properly refrigerated in the morning is still safe to eat because it isn't cool long enough for the bacteria to germinate and reproduce up to dangerous levels.
Food should not be at room temperature for more than two hours. Shallow containers or small amounts of hot food can be placed directly in the refrigerator or rapidly chilled in an ice or cold water bath before refrigerating.
Yet, if you cook your broth too long, it will develop overcooked, off-flavors that can become particularly unpleasant if you've added vegetables to the broth pot which tend to break down, tasting at once bitter and overly sweet.
The longer you cook your dish, the more water that will evaporate and the thicker the liquid becomes—that means the flavors become more concentrated, too. If you take a peek at your pot of soup and decide you'd like it to be thicker, just allow it to simmer with the lid off until it's as thick as you like.
Any active bacteria are killed by holding the stock for a minute at 150 degrees or above, and botulism toxin is inactivated by 10 minutes at the boil. But quickly reheating a contaminated stock just up to serving temperature won't destroy its active bacteria and toxins, and the stock will make people sick.
Just as when you're making stock for soups or stews, boiling will cause soluble proteins and rendered fat to emulsify into the cooking liquid. By simmering, you avoid emulsifying the fat and thus keep the stock clearer, and we found that the scum created simply settled to the bottom of the pot.
Simmer uncovered for 6 to 8 hours. Strain stock through a fine mesh strainer into another large stockpot or heatproof container discarding the solids. Cool immediately in large cooler of ice or a sink full of ice water to below 40 degrees. Place in refrigerator overnight.
For best safety and quality, plan to eat refrigerated soup within 3 to 4 days or freeze it. And avoid letting soup set at room temperature for more than TWO hours. Don't put a large pot of hot soup directly into your refrigerator.
It can take a long time to get through the danger zone when cooling a large batch of chili, soup or stew. The soup must cool from 140 to 70 °F in 2 hours and from 70 to 40 °F in no more than 4 hours.
A large pot or container of food that is hot should not be placed in the refrigerator or freezer. The hot food can raise the temperature inside the refrigerator/freezer which can be a risk for food already in the appliance.
Within 2 hours of cooking food or after it is removed from an appliance keeping it warm, leftovers must be refrigerated. Throw away all perishable foods that have been left in room temperature for more than 2 hours (1 hour if the temperature is over 90° F, such as at an outdoor picnic during summer).
After it's come to a boil and you've turned it down to a simmer, let it cook for awhile. 10 minutes, 15 minutes... whatever you want. Just know the longer you cook it, the more flavor that will come out of the food and into the soup.
Myth: Hot food will spoil if refrigerated before cooling to room temperature. Facts: Just the opposite. Give your fridge some credit. It's designed to chill food and keep it cold.
Homemade chicken broth is a laborious task but reaps delicious results. In the refrigerator, your homemade broth will last 3-4 days. To extend your broth's freshness, store the broth in the freezer for up to 6 months.
Do you simmer this stock uncovered? A. Yes, but don't let it simmer too hard (a bare simmer is best) because you don't want the liquid to reduce too quickly. In fact, if you have the time, you could partly cover the pot with the lid.
Just add acid! A small amount of an acidic ingredient like lemon juice added at the end of cooking brightens flavors, especially in long-simmered bean soups or rich meat-based soups. Start with a little bit of acid, taste and adjust, until your soup tastes balanced and bright.
There are no limits to how many times you can safely reheat leftover home-cooked meals. However, best practice is to limit the number of times you do so. More often than not, you wouldn't need to reheat one type of dish more than once.
Does cooking kill salmonella? Thorough cooking can kill salmonella. But when health officials warn people not to eat potentially contaminated food, or when a food is recalled because of salmonella risk, that means don't eat that food, cooked or not, rinsed or not.
The temperature range at which disease- causing bacteria grow best in time/temperature control for safety food (TCS) is called the temperature danger zone. Temperature danger zone is between 41°F and 135°F. TCS food must pass through the temperature danger zone as quickly as possible.
160°F/70°C -- Temperature needed to kill E. coli and Salmonella. While Salmonella is killed instantly at temperatures above 160F keeping the temperature for longer periods of time at lower temperatures will also be effective. See the chart below.
Allowing your soup to simmer can help it thicken, since it will help some of the liquid evaporate away. This will work better if you've added a thickening agent, such as cornstarch.
Traditionally, you want it at a very slow simmer, approximately 200 F, 94 C. This is essentially the same for all stocks. This is one case where very few people actually use a thermometer; the visual indication of slow occassional bubbles is a good sign you are the right temperature.
Simmering occurs between about 185 to 205ºF (85 to 96ºC). Most stews and braises are cooked at this relatively low temperature. The best way to monitor the temperature of a simmer is visual. Slow Simmer: A low heat with very little activity in the pot.
After preparing your soup, if you don't plan on serving it within two hours, refrigerate it at just below 40 F or keep it at a constant temperature of 140 F or above. Temperatures between 40 and 140 F allow for the growth of harmful bacteria in your soup.
The desired cooking temperature of soup from a food safety standpoint is 165°F – but to be sure – soups can be cooked to near boiling temperature (212°F).
TCS food must be cooled from 135°F to 70°F within 2 hours and completely cooled to 41°F or below within 6 hours. TCS food prepared from ingredients at room temperature must be cooled to 41°F or below within 4 hours. Properly cooked chili is cooled from 135°F to 70°F in 1 hour.
Soup or stew left out for more than two hours (including overnight) should be discarded according to the USDA. Even if you reheat it to kill bacteria, there may be toxins made by the bacteria, which reheating can't destroy. This applies to all soups and stews, with or without meat.
When you blow into the hot liquid, yes, the air you're causing to come into contact with the liquid is cooler than the liquid itself, and so that heat exchange will help your beverage cool faster.
Reheating on the stovetop is a great way to return a lot of foods close to their original texture, especially things with a lot of moisture like soups and stews. Stick to low to medium heat, and stir often to promote even heating.
Dangerous bacterial growth occurs between 41 and 135 degrees F. This spectrum is known as the danger zone for foods. Potentially harmful bacteria grows most rapidly at these temperatures. Placing large batches of hot foods in the fridge can raise the temperature of the fridge into this danger zone.
"[This study shows that] we can put 90 degree hot soup into a plastic bowl and the melamine you would get from that is 600 times lower than the most stringent exposure limit we have."
It is a myth that bacteria are killed at temperatures below 40 degrees. In fact, bacteria growth is slowed, but not stopped. The only way to kill bacteria by temperature is by cooking food at temperatures of 165 degrees or more. Bacteria also die in highly acidic environments like pickle juice.
Leaving food out too long at room temperature can cause bacteria (such as Staphylococcus aureus, Salmonella Enteritidis, Escherichia coli O157:H7, and Campylobacter) to grow to dangerous levels that can cause illness.
Hot held and cold held foods can be served for four hours without temperature controls if they are discarded after the four-hour time limit. Cold foods can be served for six hours as long as the food temperature stays below 70° Fahrenheit.
A general rule of thumb is that soup can be stored in the refrigerator for about three days, but you should always taste your dish before deciding to reheat.
Simmered food takes much longer to cook than boiled food, but the depth of flavors you're able to achieve are well-worth the extra time. A soup that's simmered for hours—such as chili or beef stew—becomes hearty and wholesome comfort food.
(It helps draw out nutrients and minerals from the bones into the stock.) Simmer the stock for 6 to 8 hours, covered, keeping an eye on it to make sure it stays at a simmer. Strain the stock through a fine-meshed sieve. Let cool.
It's often used for soups, stews and slow cooking meat, especially in a cast iron Dutch oven on the stovetop. The definition of simmer is to cook a liquid just below the boiling point (212°F), with a range around 185°F to 205°F.
Simmering occurs between about 185 to 205ºF (85 to 96ºC). Most stews and braises are cooked at this relatively low temperature. The best way to monitor the temperature of a simmer is visual. Slow Simmer: A low heat with very little activity in the pot.
In the culinary arts, to simmer something means to cook it in liquid at a temperature ranging from 180 F to 205 F (at sea level, the temperatures will be lower at higher altitude). With simmering you'll see bubbles forming and gently rising to the surface of the water, but the water is not yet at a full rolling boil.
Eight to ten hours, or overnight in a slow cooker, is about the average time you would simmer a stock. Some restaurants cook it much longer, reducing it to an intense, flavor component that can be added by judicious spoonfuls to sauces and braises.
