Why We Love This Instant Pot Minestrone Soup Recipe

Soup season is in full swing, and we could not be happier! Soups are the ultimate comfort food, especially when they are Italian-inspired. We regularly make our Italian Wedding Soup and Pappa al Pomodoro.

So obviously we’ve been making a lot of soup lately. Today’s minestrone is an Instant Pot variation on our reader-favorite minestrone. Loaded with tons of healthy vegetables, creamy beans, and filling pasta – this soup is super hearty, healthy, and is oh-so-delicious! It’s basically a hearty vegetable soup with some extra goodies to make it filling and satisfying to warm you right up on a cold day.

Our favorite part of this instant pot minestrone soup is the authentic slow-simmered Italian flavors but, it’s ready in 40 minutes! That’s the reason we love our Instant Pot; the all-day flavors this appliance can produce in under an hour.

And if you can’t believe that you can achieve so much flavor in such a short amount of time, our Instant Pot Veggie Curry and Vegetarian Burrito Bowls will surely help change your mind!

Key Ingredients for Making Pressure Cooker Minestrone

ingredients with labels for this recipe

Pasta

Any small-shaped pasta, such as macaroni or mini shells, will work beautifully in this dish. If you follow a gluten-free diet, feel free to use your favorite gluten-free pasta. For more fiber, use whole wheat pasta.

Extra-Virgin Olive Oil

Olive oil is used to cook the veggies and for drizzling on top of the soup as a finishing garnish.

To saute the veggie, we recommend using quality virgin olive oil. The reason is that the temperature required for a quick saute destroys the qualities that make it extra virgin olive oil.

To finish, use a high-quality extra-virgin olive oil as the fruity and grassy flavors will be pronounced and add an extra depth of flavor to this already tasty soup.

Vegetables: Carrots, Celery, Onion, Garlic

  • Carrots: Look for carrots that are dry and free from any signs of sprouting. Avoid purchasing carrots that have become soft or have visible rot. Peel and chop the carrots to about the same size as the onion and celery.
  • Celery: Look for fresh, crisp, clean, medium-sized celery stalks that are pale green. Cut into small pieces, similar in size to the carrots and onion, so it will cook and be tender in the same amount of time. 
  • Onion: We recommend using a diced sweet onion but feel free to use white.
  • Garlic: Freshly finely chopped is best but feel free to use pre-chopped if that’s what you have on hand. 

Dry White Wine

Dry white wine brings out the flavors of this delicious soup while also adding another note of acidity. We prefer to use Italian whites such as Orvieto or Pinot Grigio but feel free to use your favorite; just be sure to use a brand that does not have a lot of oak or residual sugar.

Vegetable Broth

Vegetable broth adds a deep savory element to this soup. Our favorite brand is Imagine No Chicken as we find the taste superior to other brands in that it is not bitter or dark. However, feel free to use your favorite store-bought vegetable broth. If you eat poultry you can use chicken broth or feel free to make your own chicken stock.

Red Kidney Beans

Beans add protein and fiber to this dish. Before adding to the soup, be sure to rinse and drain.

Feel free to use your favorite brand of red kidney beans but, if you prefer white beans, swap for cannellini beans which is just white kidney beans.

And no matter if you use red or white, look for no salt added if you are on a reduced-sodium diet.

Diced Tomatoes

Tomatoes help add acidity to the soup. If you cannot locate a can of petite diced tomatoes, feel free to use whole Italian-style plum tomatoes and chop or break them into smaller pieces before adding them into the Instant Pot.

Spinach

We recommend using fresh baby spinach for this recipe. Baby spinach is so tender and less bitter than full-grown spinach it requires less cooking time and adds a luscious texture to the finished dish.

We also recommend using pre-packed baby spinach as it is triple washed, so it only needs a quick rinse and spin before adding to the soup.

However, if you happen to have full-sized spinach, feel free to use it, just be sure to chop it into bite-sized pieces before adding it to the recipe.

Basil

Used to add a fresh, subtly sweet flavor to finish off the dish. We do not recommend using dried basil as it won’t add the same bright notes that fresh basil will. If you do not have fresh, skip adding this herb altogether.

Seasonings: Salt, Pepper, Italian Seasoning

Italian seasoning is a prepackaged dry blend located down the spice aisle of most supermarkets. We find that this premade blend has a nice balance of herbs that really helps wake up the soup. 

Note that we recommend using table salt for this recipe. However, you can use kosher salt, but you will want to double it. See why here.

Step By Step Instructions for This Easy Instant Pot Minestrone Soup Recipe

step by step photos of making instant pot minestrone

Step 1: Sauté Vegetables

Set the Instant Pot to sauté mode for 9 minutes. Heat oil in the inner pot. Add onion, garlic, carrots, celery, Italian seasoning, salt, and pepper and sauté until the vegetables start to brown, about 8 minutes. Add wine and stir. Cook for an additional minute. Note: If you are using an electric pressure cooker without a saute function, you can do this step in a saute pan or soup pot on the stove over medium heat.

Step 2: Add Broth and Pasta

Add broth and pasta to Instant Pot.

Step 3: Cook the Soup

Place lid on the Instant Pot and set the pressure valve to “sealing”. Set for high pressure for 2 minutes. When time goes off, carefully turn the valve to quick release and allow the steam to escape. {Note: if you are new to using an instant pot, the cook time refers to the amount of time the soup will cook once it reaches full pressure. It can take several minutes to come to full pressure before the time will start counting down.}

Step 4: Finish Soup

Remove lid. Set the cook function to sauté for 5 minutes. Stir in tomatoes, beans, and spinach. Bring to a simmer, stirring often. Turn off the Instant Pot once the soup is simmering and the spinach has wilted.

Serve warm and garnish with basil and a drizzle of extra virgin olive oil.

FAQ And Expert tips For Cooking Minestrone In An Instant Pot

How do I store leftovers?

Store any leftover soup in an airtight container in the fridge for up to 5 days.

When ready to reheat, place leftover minestrone in a saucepan and bring to a gentle simmer over medium-high heat, stirring occasionally. Simmer only until soup is warmed through; otherwise, the pasta will become overcooked. For best flavor, leave out the basil until the soup is warmed. Salt and pepper to taste if the flavors seem dull.

Can pressure cooker minestrone soup be made ahead?

Soups are one of the best make-ahead meals. The longer the flavors sit and marry together, the more robust they become. However, we do have some make-ahead notes for this recipe:
1) The pasta in this recipe is nicely al dente when prepared as directed and served immediately; however, it will continue to absorb liquid as it sits. Therefore, you will need to add more broth when ready to reheat and enjoy.
2) If you prefer a more al dente pasta and want to make ahead or freeze it, we recommend cooking the pasta separately and adding it to the soup just before serving.
3) The fresh basil tastes best when added right before serving so, wait until the soup is reheated before garnishing.

Can minestrone soup be frozen?

Yes! Allow soup to completely cool in the fridge before portioning out into freezer-safe containers. Tightly cover and freeze for up to 3 months.

When ready to enjoy, thaw overnight in the fridge or directly reheat from frozen in the microwave, breaking up ice as it thaws every 4 minutes.

Can I double this recipe?

This recipe can certainly be doubled, but make sure not to fill your Instant Pot past the fill line when pressure cooking.

Can this soup be made gluten-free?

To make this hearty soup gluten-free, simply substitute in your favorite gluten-free pasta. Our personal favorite is brown rice macaroni but feel free to use whatever you prefer!

What can I serve with this Instant Pot minestrone soup?

This minestrone soup is hearty enough to serve as a main course with a side garden salad. To keep it simple you can always just pick up a loaf of crusty bread or make our one-hour homemade whole-wheat bread recipe. Or it could be served as a tasty first course for an Italian vegetarian meal consisting of vegetarian mushroom lasagna or spinach stuffed shells.

Variations To Try

  • Making soup is a great way to use up whatever seasonal vegetables you have on hand. Add sliced zucchini or 2-inch lengths of green beans to bulk up the veggies when you add the macaroni and broth to the Instant Pot. Or add frozen cut green beans when you put in the spinach, tomatoes, and beans at the end.
  • Swap out the kidney beans for another type of bean such as chickpeas or cannellini.
  • Use a different type of pasta such as mini shells or ditalini. For more fiber use whole-wheat pasta.
  • Up the protein by adding in diced cooked chicken or browned Italian sausage when the canned beans and tomatoes are added.
  • Feel free to use Swiss Chard or escarole instead of baby spinach.
  • Boost the flavor of the broth by adding a parmesan rind, however; if you’d like the keep this vegan, skip this! We also like to top our bowls with Parmesan cheese. (Nutritional yeast is a great vegan alternative.)
  • Skip the dry white wine and use ¼ cup water plus 2 teaspoons lemon juice.

  • To make this gluten-free substitute brown rice macaroni
  • Tip: This can be doubled, but make sure not to fill your Instant pot past the fill line when pressure cooking. 
  • Make Ahead: The pasta in this recipe is nicely al dente when prepared as directed and served immediately, however it will continue to absorb liquid as it sits. This being the case you will need to add more broth to reheat the leftovers. If you prefer a more al dente pasta and want to make this ahead or freeze it, we recommend cooking the pasta separately and adding to the soup just before serving. The basil is best when added just before serving, so if you like wait until after it is reheated to add to the soup.
