Ingredients for Minestrone Instant Pot
Pantry staples meet fresh veggies for this cozy Italian classic.
| Ingredient | Amount | Notes |
|---|---|---|
| Ditalini Pasta 🍝 | 1 ½ cups | Small pasta shape, uncooked |
| Canned Cannellini Beans 🫘 | 2 cans | Drained and rinsed thoroughly |
| Canned Diced Tomatoes 🍅 | 2 cans | With juices included |
| Vegetable Broth 🥣 | 4 cups | Low-sodium preferred |
| Zucchini 🥒 | 2 whole | Medium-sized, diced |
| Carrots 🥕 | 2 whole | Peeled and chopped |
| Yellow Onion 🧅 | 1 whole | Diced, about 1 cup |
| Garlic Cloves 🧄 | 3 cloves | Minced for depth of flavor |
| Fresh Spinach 🥬 | 4 cups | Chopped, packed tightly |
| Celery Stalks 🌿 | 2 pieces | Diced for texture |
| Tomato Paste 🍅 | 2 tbsp | For concentrated tomato flavor |
| Dried Oregano 🍃 | 1 tsp | Mediterranean variety preferred |
| Dried Basil 🌿 | 1 tsp | Or use fresh at triple amount |
| Olive Oil 🫒 | 2 tbsp | Extra-virgin for sautéing |

The broth and tomatoes are the backbone here. San Marzano canned tomatoes give the best flavor, but any good brand works in a pinch. Vegetable broth is key for that rich base—Better Than Bouillon is my go-to. Grab the beans and pasta from the regular grocery aisle. If you’re feeling fancy, whole foods has a great bulk section for dried herbs.
No ditalini? Small shells or elbow macaroni work just as well. Swap cannellini for kidney or great northern beans—whatever’s in the cupboard. Fresh herbs? Triple the amount of dried. Zucchini can be replaced with yellow squash (or both). And if you’re out of spinach, kale or Swiss chard hold up nicely in the pressure cooker.
This keeps 4-5 days in the fridge—honestly tastes better the next day. Freezes beautifully for up to 3 months. Pro tip: leave the pasta slightly undercooked if freezing (it’ll finish cooking when reheated).

Step-by-Step Instructions for Minestrone Instant Pot
This method delivers hearty, rustic flavor with minimal hands-on time.
Step 1: Sauté Aromatics for Depth of Flavor
Set your Instant Pot to Sauté mode and add the 2 tbsp Olive Oil. Once hot, add the diced Yellow Onion, chopped Carrots, and diced Celery Stalks. Cook for 4-5 minutes, stirring occasionally, until the onion turns translucent and the carrots begin to soften.
Add the minced Garlic Cloves and cook for 30 seconds until fragrant. Stir in the 2 tbsp Tomato Paste, 1 tsp Dried Oregano, and 1 tsp Dried Basil, cooking for another 1 minute to deepen the flavors. This step builds the foundation for your soup.
Step 2: Add Vegetables and Liquids
Stir in the diced Zucchini, 2 cans Canned Diced Tomatoes (with juices), and 2 cans Canned Cannellini Beans (drained and rinsed). Pour in the 4 cups Vegetable Broth, scraping the bottom of the pot to release any browned bits. This ensures no flavor is left behind.
Secure the lid and set the Instant Pot to High Pressure for 5 minutes. Make sure the valve is sealed. The pressure cooker will take about 10 minutes to come to pressure before the timer starts.
Step 3: Release Pressure and Add Pasta
Once the cooking time is complete, carefully switch the valve to Quick Release. When the pressure has fully released, open the lid and stir in the 1.5 cups Ditalini Pasta. The pasta will cook directly in the hot soup, absorbing all the delicious flavors.
Set the Instant Pot back to Sauté mode and cook for 8-10 minutes, stirring occasionally, until the pasta is al dente. If the soup is too thick, add a splash of water or broth to reach your desired consistency.
Step 4: Finish with Spinach and Serve
Turn off the Instant Pot and stir in the 4 cups Fresh Spinach until it wilts into the soup, about 1-2 minutes. The residual heat will soften the spinach perfectly without overcooking it.
Ladle the minestrone into bowls and top each serving with a sprinkle of the 0.5 cup Parmesan Cheese**. The cheese adds a salty, nutty finish that ties everything together. Serve hot and enjoy the comforting, rustic flavors of this classic Italian dish.
Pro Tips For Making Minestrone Instant Pot
- Pre-Cook the Pasta: I learned this the hard way—add the ditalini separately after pressure cooking, or it’ll turn to mush. Cook it al dente in a pot, then stir in at the end.
- Rinse the Beans: Sounds tedious, but rinsing the canned cannellini beans removes that metallic taste and keeps the broth clear. Takes 20 seconds, worth every one.
- Skip the Overfill: Resist the urge to max out the Instant Pot—minestrone expands, and you’ll risk a burn notice. Stay under the 2/3 mark, even if it means a second batch.
- Use Fresh Zucchini: After using sad, spongy zucchini once, I now pick firm, medium-sized ones. They hold their shape and soak up flavor better than the giant, seedy ones.
Dietary Considerations for This minestrone instant pot
Vegetarian Friendly
This dish is naturally vegetarian, packed with plant-based proteins from cannellini beans and fiber-rich vegetables. Each serving delivers about 15g of protein from the beans alone, making it a satisfying meat-free option.
Gluten-Free Adaptation
To make this gluten-free, simply swap the ditalini pasta for gluten-free pasta like Barilla’s GF ditalini. Ensure your vegetable broth is certified gluten-free, as some brands contain wheat. The rest of the ingredients are naturally gluten-free.
Vegan Modification
For a vegan version, omit the Parmesan cheese or replace it with nutritional yeast for a cheesy flavor. I like Bragg’s brand for its rich, nutty taste. The soup remains hearty and delicious without any dairy.
You can also add 1 cup of cubed butternut squash for extra body and sweetness.
Low-Sodium Option
Use low-sodium vegetable broth and no-salt-added canned beans and tomatoes. This reduces sodium by about 50% without sacrificing flavor. I find Eden Organic beans work well for this.
Nut Allergy Safe
This recipe is naturally nut-free, but always check labels on canned goods and broth for potential cross-contamination. The Instant Pot method keeps everything contained, reducing risk of exposure. 💪
Nutrition Facts
Frequently Asked Questions
Can I use frozen vegetables instead of fresh?
Yes, but add them after pressure cooking to avoid mushiness. Frozen vegetables work best when stir-fried directly into the hot soup for 5-7 minutes to maintain texture.
Why add pasta after pressure cooking?
Pasta cooks quickly and can turn mushy under pressure. Adding it afterward on Sauté mode for 8-10 minutes ensures perfect al dente texture.
How do I prevent a burn notice?
Always deglaze the pot after sautéing by scraping the bottom. Add at least 4 cups of liquid before pressure cooking to avoid burning.
Can I make this ahead of time?
It keeps well for 4-5 days in the fridge. For best results, store without pasta and add it fresh when reheating.
