A perfect soup that is a complete meal in itself – beans, loads of veggies and pasta, topped with cheese and a side of bread. This tastes just like the Olive Garden minestrone soup. Vegetarian-friendly and can easily be made gluten-free and vegan.

Fall is in full swing, although not so much in California yet. But I am still craving soup! So here is a hearty and healthy vegetarian Minestrone soup made in the Instant Pot. It is a perfect combination of tasty and nutritious.

Beans, loads of veggies and pasta, all cooked in a yummy broth….so flavorful. This is a complete meal with protein, carbs, and loads of nutrients from the veggies. It is also the easiest thing to make. It is most a throw all in and let the magic pot do it’s work kind of soup.

This is a perfect Vegetarian Instant Pot Soup!

Vegan? Skip the cheese at the end!

Gluten-free? Skip the pasta or use a rice or quinoa pasta to make this gluten free.

Ingredients for Minestrone Soup

Look for all the veggies in your refrigerator…okay, not all but most veggies work great in this soup.

It is easy to customize this soup and use other veggies. I have used:

  • Carrots
  • Celery
  • Zucchini
  • Baby Spinach

I always keep some canned cannellini beans in the pantry. You can also add kidney beans if you like.

You can also cook the beans in the instant pot, which is great. Here is my recipe to make instant pot cannellini beans.

Many recipes add beans at the end after pressure cooking, but I like the canned beans cooked with the broth and veggies so they soak in the flavor.

I have tried making this soup with fresh tomatoes and with canned diced tomatoes. It works great both ways, so feel free to use any.

I used small elbow macaroni pasta in this soup. Any dry pasta works well in this recipe. I like to use dry pasta and cook it directly in the instant pot with the veggies.

If you have pre-cooked pasta ready, you can add that to this soup after pressure cooking along with the spinach and simmer for a few minutes.

How to make Minestrone Soup in the Instant Pot?

This is a very easy soup to make in the instant pot. You don’t have to simmer the pot on the stovetop for hours to get a flavorful delicious soup!

  • Start with heating oil in the instant pot and sautéing onions and garlic.
  • Then add diced tomatoes and chopped celery, carrots and zucchini.  Also add all the seasonings at this time.
  • Add in the pasta, vegetable broth and white kidney beans. Stir it all up. Make sure the pasta is under the broth. 
  • Now cook on SOUP mode in the instant pot.
  • When the instant pot beeps, manually release the pressure after 5 minutes.
  • Stir in the chopped spinach and let it sit for 5 minutes. Season with more slat and pepper if you like.
  • Garnish with parmesan cheese (optional) and minestrone soup is ready to serve.

Can I freeze this soup?

If you want to freeze this soup, leave out the pasta when pressure cooking. Cook the pasta separately and add in when reheating.

Notes

Broth: You can use “Better than Bouillon” base if you prefer. I had low sodium veggie broth at hand and used it.
Beans: Same for beans, I used white kidney beans, but any beans you have at hand would work. You could also cook the beans in the instant pot. Soak the beans in ample water for 4 hours and cook them for 20 minutes at high pressure in the instant pot. Then use them in this recipe.
Veggies: You can vary veggies to your choice. Some options are bell peppers, potatoes, sweet potatoes, kale. Add jalapenos for an extra spice kick.
Pasta: I used small elbow macaroni pasta in this soup. Any dry pasta works well in this recipe. I like to use dry pasta and cook it directly in the instant pot with the veggies. If you have pre-cooked pasta ready, you can add that to this soup after pressure cooking along with the spinach and simmer for a few minutes. 
Vegan Variation: Skip the Parmesan cheese at the end.
Gluten Free Variation: Skip the pasta or use a gluten-free pasta.
Note: The cook time has been lowered in this recipe to 5 minutes, as that has worked well too. Originally it was 10-20 minutes.

  1. I have honestly made this recipe so many times and it’s always a hit! thank you so much for a great recipe, and a great step by step guide with photos. your website is truly one of my favorite cooking websites/blogs out there.

  2. Wow! I just made this and it turned out so amazing and all family members loved it. Thank you so much, Meeta! <3

  3. This recipe is FANTASTIC!!! I printed this one and put it in my favorites folder so it can become a staple. The flavor is wonderful and you really don’t want to stop at one bowl! The white Kidney Beans make the dish so don’t skip them! I used Ziti vs. Macaroni because I love noodles. This may not be for everyone but it was wonderful (but cooked noodles continue to expand in liquid, so remember that). Thank you for such a wonderful, easy version of my favorite soup. Also, there are lots of great Parmesan Cheeses that are not made with Rennet (basically meat) and because I’m a vegetarian, I have my favorites of those cheeses.

  4. I would like to use rice and quinoa in my meal. Does the rice need to be precooked before placing the pot?

    1. Hi Rebecca – As we are pressure cooking for 5 minutes, you can add uncooked rice or quinoa to this soup, and it will cook perfectly in the same pressure cooking time. Hope you enjoy the soup!

  5. Amazing recipe made it today lunchtime and it was delicious. Will be uploading the picture shortly on Instagram and will tag you.

  6. Hello! I LOVE this soup and so does my family. Is there anyway to freeze the chopped veggies ahead for meal prep? How would this adjust the cooking instructions?

    1. Hi Ashlyn – you can surely chop the veggies and freeze them. The cooking time would not change, the instant pot will just take longer to come to pressure. You can also move the bag to the refrigerator the night before you plan to make the soup.
