No. health experts recommend that soup should be reheated once. The main reason is that the more soup is frozen and reheated, there are high the chances of bacterial growth that can lead to potential food-borne illnesses.

According to food standards, you should reheat any meat-based soup once. As you reheat soup continuously, the quality tends to decrease with time.

One of the most valuable features of the Instant Pot is the ability to cook an entire bowl of soup in its container. Here are some helpful hints for reheating soup in the instant pot.


  1. First, leave your soup in the insert pot.
  2. You may leave it in the refrigerator covered by a silicone lid or some plastic wrapping until you are ready to reheat it.
  3. After removing the silicone top, place the insert pot into the instant pot.
  4. You may add some water to the pot.

  3. Defrost the soup for 10 minutes.

Reheat frozen soup on a stove

For frozen soup, this is by far my preferred method of warming. Because I like my soup to have an irresistible taste, I always cook it on the burner.

The beauty of this procedure is that you can flavor your soup even more before reserving it.


  1. Fill your sink with warm water and place the container with the soup.
  2. Allow the soup to warm for 5 to 10 minutes.
  3. Carefully put your soup into a reheating vessel.
  4. Put the pot on the stovetop.
  5. Add a sizeable amount of water into the pot.
  6. Stir the mixture.
  7. Cover the pot with a lid.

Stirring frequently prevents the soup from burning.

There are many types of soup you can reheat with the above methods. Below are 3 types of soup elaborated step by step.

Reheat soup that contains pasta

Soup that contains pasta is mainly fed to kids. The standard type of pasta is noodles which you should be careful about the cooking time since it overcooks easily.

The pasta may lose its taste once it becomes gooey and soft. Therefore, store the soup you are freezing without pasta and add the noodles.


  1. First, defrost the soup in a bowl containing warm water
  2. Another way is to thaw the soup in the refrigerator after removing it from the freezer.
  3. Nuke the soup on medium heat.
  4. Let the soup heat up with regular stirring.
  5. Cook the noodles in a separate pot without any spices.
  6. Add pasta to the soup and stir.
  7. When ready, serve.

Reheat a creamy soup

The creamy soup is highly nutritious. It would be best to be careful when reheating creamy soup since it’s very saturating due to its dense texture.

Lumps appear when you reheat different ingredients together. Therefore, it’s good to add cream at the end.


  1. Thaw the soup overnight.
  2. Nuke the soup on medium heat while stirring the soup frequently.
  3. Finally, serve it with some cream.

Creamy soup tends to stick to the bottom of the pot and avoid reheating at high temperatures. Due to the creamy nature of the soup, it may burn more quickly.

Reheat soup with vegetables

When you have diced vegetables or potatoes leftover to store, it’s recommended you leave the dish undercooked in the first place.


  1. the soup boils, leave it to simmer. The vegetables will cook thoroughly.

You need to occasionally stir the vegetables to ensure they don’t overheat.

How many times can you reheat soup?

Reheating soup is easy, whether using a microwave, instant pot, or a stovetop. When defrosting soup, it should be done on a fridge or use the above methods.

Reheating soup more than once is not recommended. Therefore, refrigerating whatever is left after taking what you eat is highly good for your health.

The general rule to follow is that if you are reheating meat or chicken broth, boil it for 3 minutes to ensure you kill all harmful bacteria.

Soup is the most flexible of all foods to reheat since it doesn’t cause scorching. However, soup mixed with flour or cream is hard to boil since scorching may occur. The soup may be over-reduced, become salty, thick, and cloudy.

As long as the soup doesn’t smell or taste “strange,” when you take it out of the fridge, bring it to a boil, then reduce the heat to low and continue to stir while it simmers quietly for 3 minutes.

How long is frozen soup good for?

The general rule is that soup is good for 3 days when stored in the refrigerator. Before reheating soup, it is good to taste the dish first.

Vegetable-based soup may have a longer shelf life.

Chicken-made soup will last for 5 days in the fridge.

Creamy soup will last for 3 days, while seafood soup has a shelf life of 2 days.

Amazingly, some soups with a longer shelf life than others will still be in the fridge. The keeping time of soup depends on 2 things. First, the ingredients that make up the soup, and secondly, how efficient the cooling method was.

Many recipes will offer you a conservative storage duration, so learn to trust your nose and taste buds and be on the lookout for weird aromas and sourness.

Depending on the contents of the soup, frozen soup has a shelf life of 3 months. This is dependent on proper freezer temperatures. After defrosting, trust your instincts, just as you would with refrigerated soups. You’re better off throwing it if it appears suspect.
