Looking for a way to get your daily serving of vegetables in one delicious sitting? This instant pot minestrone soup is the answer. It is thick, colorful, and incredibly satisfying, proving that healthy food doesn't have to be boring. By using the pressure cooker, we condense the long simmering time of a traditional Italian minestrone soup instant pot into just a few minutes of active cooking.

This recipe is also a fantastic "fridge clearer." While we use carrots, celery, and zucchini here, you can easily swap in whatever seasonal vegetables you have on hand. Kale instead of spinach? Perfect. Green beans instead of zucchini? Go for it!

The most common fear when making a vegetable soup instant pot with pasta is that the noodles will turn into mush. In a traditional stovetop recipe, you often cook the pasta separately. However, for a true one-pot italian minestrone recipe, the secret is the timing.

Calculated accurately, 5 minutes of high pressure followed by an immediate quick release is the perfect duration for small pasta shapes like ditalini or mini shells. They will emerge perfectly al dente. If you prefer your pasta very soft, you can let the pressure release naturally for 2 minutes before venting.

In this healthy pressure cooker soup, we use both Kidney beans and Cannellini beans. This isn't just for color! Kidney beans provide a firm, meaty texture, while Cannellini beans (also known as white kidney beans) are much creamier and tend to break down slightly, which helps thicken the broth and give the soup a richer mouthfeel without adding any cream or flour.

Instant pot minestrone soup is best served with a generous sprinkle of freshly grated Parmesan cheese and a side of crusty sourdough bread for dipping.

* Meal Prep: This soup actually tastes even better the next day as the flavors have more time to meld. * Storage: Store in airtight containers in the fridge for up to 5 days. * Freezing: You can freeze this soup for up to 3 months. However, be aware that the pasta will continue to absorb liquid even after freezing, so you may need to add a splash of broth when reheating to bring it back to the right consistency.

Enjoy a bowl of comfort that loves you back!

Ingredients

  • 2 tbsp olive oil
  • 1 small onion, diced
  • 2 carrots, diced
  • 2 stalks celery, diced
  • 1 medium zucchini, diced
  • 3 cloves garlic, minced
  • 1 tsp dried oregano
  • 1 tsp dried basil
  • 1/2 tsp salt
  • 1/4 tsp black pepper
  • 1 can (28 oz) diced tomatoes
  • 6 cups vegetable broth
  • 1 can (15 oz) kidney beans, rinsed and drained
  • 1 can (15 oz) cannellini beans, rinsed and drained
  • 1 cup small pasta (ditalini or elbow)
  • 2 cups fresh spinach, roughly chopped
  • Grated parmesan and fresh parsley for garnish

Instructions

  1. 1

    Sauté the Aromatics

    Set the Instant Pot to 'Sauté' mode. Add olive oil, onion, carrots, and celery. Cook for 5 minutes until veggies begin to soften. Stir in the garlic, oregano, basil, salt, and pepper for another minute.

  2. 2

    Combine Ingredients

    Add the zucchini, diced tomatoes (with juice), vegetable broth, kidney beans, and cannellini beans. Stir well. Finally, stir in the dry pasta.

  3. 3

    Pressure Cook

    Secure the lid and set the valve to 'Sealing'. Select Manual/Pressure Cook and set the time for 5 minutes. (Note: The pasta will cook perfectly in this time!)

  4. 4

    Quick Release and Finish

    Once the timer beeps, immediately do a Quick Release of the pressure to prevent the pasta from overcooking. Open the lid, stir in the fresh spinach until wilted, and season with extra salt or pepper if needed.

Frequently Asked Questions

Can I make Instant Pot minestrone soup gluten-free?
Yes! Simply substitute the pasta with a gluten-free pasta variety (such as brown rice ditalini) or replace it entirely with diced potatoes or extra beans. The rest of the recipe is naturally gluten-free.
Why did my pasta turn mushy in the Instant Pot minestrone?
Overcooking is the main culprit. For al dente pasta, always do an immediate Quick Release as soon as the timer beeps — do not allow the pressure to release naturally, as the residual heat will continue cooking the pasta. If you prefer very firm pasta, you can also cook the pasta separately and stir it in after pressure cooking.
Can I freeze Instant Pot minestrone soup?
Yes, but with a caveat: the pasta will absorb liquid and soften significantly upon freezing and reheating. For the best results, freeze the soup without the pasta. Cook fresh pasta and add it to the thawed, reheated soup. Frozen soup lasts up to 3 months.
How can I make this minestrone soup more filling?
Add more protein by stirring in a drained can of chickpeas along with the beans, or add cooked Italian sausage. You can also increase the pasta amount to 1.5 cups. Serving with crusty sourdough bread for dipping also makes it a heartier meal.
