Once the cooking process has stopped, quick release and carefully remove the lid.
Stir in the fresh spinach and beans. Cover the soup loosely to allow the greens to wilt and the beans to heat through.

Note: Cook time can vary depending on the model of your pressure cooker, check the manual if you have any questions.

Ingredient Notes and Substitutions

The complete list of ingredients to make this recipe is above. Below are notes about some of the ingredients, along with ideas for substitutes.

Vegetables – Any combination of vegetables can be sued to make minestrone soup in an instant pot. The vegetables listed in this recipe are what I normally use to make this soup. Other suggestions are parsnips, potatoes, mushrooms, green beans, and peas.

Beans – I like to use white kidney beans or cannellini beans, but any type of beans such as black beans or red kidney beans can be used.

Tomatoes – You can use fresh tomatoes or low-sodium canned diced tomatoes. Either one will work.

Vegetable broth – I like to use homemade vegetable broth to make minestrone soup, but you can also use low-sodium packaged broth if you prefer.

If you aren’t following a vegan or vegetarian diet, you can substitute vegetable broth with chicken broth as well.

Spinach – This wilts quickly and adds a nice flavor to the soup. It can be substituted with kale or escarole.

Pasta – Smaller-sized pasta works best in soups, small shell pasta, elbow pasta or ditalini pasta are all good choices. I like to use whole wheat pasta when it’s available.

How to store leftovers

Leftover easy instant pot minestrone soup can be stored in the refrigerator for 4 days in an airtight container or you can freeze the soup for 3 months without the pasta (to prevent soggy pasta) in a freezer-safe container.

Reheat leftover soup on top of the stove over low heat.

Recipe variations

There are so many ways to make this delicious soup your own, here are a few suggestions to make this soup your own.

Spicy – Add a teaspoon or two to taste of red pepper flakes to the soup for a spicy minestrone soup.

Meat – Add cooked shredded chicken, ground beef or Italian sausage for a meaty version.

Whole grains – Instead of pasta, replace the pasta with cooked barley, farro or rice.

Serving suggestions

Serve this delicious minestrone soup garnished with grated parmesan cheese and fresh herbs such as chopped fresh parsley, or fresh basil and a hunk of crusty bread and arugula or chopped salad for a complete and nutritious dinner.

💡Tips

To prevent burning yourself, use kitchen tongs or a wooden spoon to turn the release valve on the electric pressure cooker when doing the quick pressure release.
If you plan on leftovers cook the pasta separately and add the cooked pasta to the soup just before serving.
Add a little extra flavor by stirring in up to 2 tablespoons of balsamic vinegar with the spinach and beans.

What’s the difference between minestrone soup and vegetable soup?

Classic minestrone soup is a hearty soup made with vegetables, beans and pasta. Vegetable soup is a thinner soup that’s made mostly with vegetables and not as hearty as minestrone soup.

Can you make vegetable minestrone soup in a slow cooker?

Yes! Prepare the recipe as instructed in the recipe card but saute the vegetables in a heavy skillet before adding them to the slow cooker. Cook for 4 hours on low. Add the baby spinach and beans, and cover until the spinach has wilted.
