I love minestrone soup. I have been making it one shape or another for many years. I have made it on the stove top, crockpot, and instant pot. Of course, cooking soup in the instant pot is my favorite. I love that you can go from chopping fresh vegetables to a delicious soup that warms your bones in the middle of winter.

Can I add different vegetables to minestrone soup?

Yes, you totally can! You can switch up the potatoes and use any variety you have on hand. Cut up butternut squash is also amazing in minestrone soup!

As far as other vegetables, you can use whatever you like best. That’s the beauty of making soup! 

How long does homemade minestrone soup stay fresh in the fridge?

This soup will stay fresh up to 4 days. It’s a great soup to make on Sunday and eat for lunch during the week. You could ladle it into individual containers for an easy grab-and-go meal. I like these Twist ‘n Loc containers.

Can I freeze pressure cooker minestrone soup?

Soup is so easy to freeze and minestrone soup is no exception! If you are intentionally making this soup as a freeze meal, I would omit the pasta. Only because it does tend to get a bit soft after freezing and reheating. 

However, I freeze soup with pasta in it all the time and have never heard any complaints about the state of the noodles. So, don’t worry about it too much.

Here is how to freeze minestrone soup:

  1. Cook the soup and let it cool to room temperature. 
  2. Ladle the soup into freezer safe containers. You can also use freezer bags to save space. 
  3. Seal the containers well.
  4. Label the container and date it. Wet erase markers works great for this so you can reuse the container (although, the marker does tend to smudge as you defrost, but you will know what it is by then), or add a piece of masking tape to the container and label the tape.
  5. Freeze up to 3 months.
