Ingredients for instant pot minestrone
- 2 tbsp olive oil
- 1 large onion, diced
- 2 carrots, sliced
- 2 celery stalks, sliced
- 3 garlic cloves, minced
- 1 medium zucchini, diced
- 1 large potato, cubed
- 1 can (14.5 oz) diced tomatoes
- 6 cups vegetable broth
- 1 cup canned cannellini beans, drained and rinsed
- 1/2 cup small pasta shells
- 1 tsp dried oregano
- 1 bay leaf
- 1/2 tsp salt

Don’t have zucchini? Swap it for green beans or spinach without changing the cook time—both work great in instant pot minestrone. I’ve also subbed regular potatoes with sweet potatoes before and it gives this hearty Italian bowl a totally different vibe.
Real talk: skip the pasta shells if you’re making this ahead and freezing it, then add fresh pasta when you reheat. This keeps everything from getting mushy, and honestly it tastes way better that way.
Step-by-step instructions
1. Turn your Instant Pot to the sauté setting and add 2 tbsp olive oil. Once it’s shimmering, add your diced onion and cook for about 3 minutes until it starts getting soft. You’ll hear it sizzle and the kitchen smells amazing already.
2. Toss in the sliced carrots, celery, and minced garlic, stirring everything together. Let it cook for 2 more minutes so the garlic doesn’t burn. Don’t panic if it looks a little crowded—there’s plenty of room.
3. Pour in the 6 cups vegetable broth and scrape the bottom of the pot with a wooden spoon (this gets all the good flavor stuck there). Add your cubed potato, diced zucchini, diced tomatoes with their juice, cannellini beans, oregano, and bay leaf.
4. Cancel the sauté setting and seal the lid. Set it to high pressure for 8 minutes. I always double-check that the valve is in the sealed position because I learned that lesson the hard way once.
5. When the timer goes off, carefully do a quick release by moving the valve to venting. Wait about 1 minute for the steam to release, then open the lid. The vegetables should be tender and the broth should smell absolutely incredible.
6. Switch back to sauté mode and add your 1/2 cup pasta shells, 1/2 tsp salt, 1/4 tsp black pepper, and remove that bay leaf. Stir it all together and let it cook for about 4 minutes until the pasta is al dente.
7. Taste it and adjust your seasoning if needed—I usually add a pinch more salt and fresh cracked pepper. Ladle this instant pot minestrone into bowls and top with that grated Parmesan cheese. Mine always sticks a little to the bottom and that’s totally fine and honestly adds character.
