Ingredients
Essential Ingredients
When I make classic Instant Pot minestrone soup, I use simple, fresh ingredients. Here’s what you need:
- 1 tablespoon olive oil
- 1 onion, diced
- 2 carrots, diced
- 2 celery stalks, diced
- 3 cloves garlic, minced
- 1 zucchini, diced
- 1 can (14 oz) diced tomatoes, with juice
- 6 cups vegetable broth
- 1 can (15 oz) kidney beans, rinsed and drained
- 1 cup green beans, trimmed and cut into 1-inch pieces
- 1 teaspoon Italian seasoning
- Salt and pepper to taste
- 1 cup small pasta (such as ditalini or elbow)
- 2 cups fresh spinach
- ¼ cup grated Parmesan cheese (optional, for serving)
These ingredients create a rich and hearty soup. The olive oil adds a nice base. The onion, carrots, and celery bring sweetness and texture. Garlic and zucchini add depth and flavor. The diced tomatoes and vegetable broth make the soup juicy and warm.
Kidney beans and green beans add protein and crunch. Italian seasoning gives it that classic flavor. Don’t forget the salt and pepper; they enhance everything. The small pasta makes it filling, while fresh spinach adds color and nutrients. Parmesan cheese is a tasty topping that makes the soup even better.
Feel free to adjust the veggies based on what you have. This soup is flexible and allows for creativity!

Step-by-Step Instructions
Prepping the Vegetables
To start, I turn on my Instant Pot and select the Sauté function. I add one tablespoon of olive oil and heat it for about a minute. Next, I toss in the diced onion, carrots, and celery. I sauté these for about five minutes until they soften. The aroma fills the kitchen and makes me hungry!
Now, I add three cloves of minced garlic and one diced zucchini. I sauté these for another two minutes. This makes the soup taste fresh and bright.
Building the Soup Base
Once my veggies are prepped, I add one can of diced tomatoes with juice and six cups of vegetable broth. I also include one can of kidney beans, rinsed and drained, and one cup of trimmed green beans cut into one-inch pieces. To enhance the flavor, I sprinkle in one teaspoon of Italian seasoning, along with salt and pepper to taste. I stir everything well to combine.
Instant Pot Cooking Process
With the soup base ready, I close the lid of the Instant Pot. I make sure the valve is set to sealing. I select the Manual or Pressure Cook setting and set the timer for five minutes. This is where the magic happens!
Once the cooking is complete, I quickly release the pressure by turning the vent to the venting position. I always do this carefully to avoid steam burns.
Final Touches
After opening the lid, I add one cup of small pasta, like ditalini or elbow. I select the Sauté function again and cook for an additional five to seven minutes until the pasta is tender. I stir frequently to keep it from sticking.
Finally, I stir in two cups of fresh spinach until it wilts. I taste the soup and adjust the seasoning as needed. Now my Classic Instant Pot Minestrone Soup is ready to enjoy!
Tips & Tricks
Perfecting the Sautéing Process
Sautéing your vegetables is key to a great minestrone. It builds flavor and texture. When you sauté, you release natural sugars. This adds sweetness and depth. Start with onion, carrots, and celery. Cook them for about five minutes. They should soften and turn fragrant. Then, add garlic and zucchini. Sauté them for two more minutes. This step makes the soup rich and tasty.
Adjusting Cook Times
Different pasta types cook at different speeds. If you use small pasta like ditalini, five minutes is perfect. If you prefer larger pasta, adjust the time to seven minutes. Always check the pasta for doneness. You want it tender but not mushy. If you like al dente, cook it for less time. Keep stirring to ensure even cooking.
Enhancing Flavor
To take your minestrone to the next level, try adding fresh herbs. Basil and parsley work great. You can also play with spices. A pinch of red pepper flakes adds heat. Adjust salt and pepper to your taste. If you want a little zest, add a squeeze of lemon before serving. These tweaks can make your soup shine!
Pro Tips
- Prep Ingredients Ahead: Chop all vegetables and measure out ingredients in advance to make the cooking process quicker and easier.
- Adjust Seasoning: Taste the soup before serving and adjust the seasoning as necessary for optimal flavor.
- Use Fresh Herbs: For a burst of flavor, consider adding fresh herbs like basil or parsley before serving.
- Store Leftovers Properly: Store any leftovers in an airtight container in the fridge for up to 3 days, or freeze for longer storage.

For those needing gluten-free options, you can swap the pasta. Use gluten-free pasta made from rice or quinoa. You can also skip the pasta altogether if you prefer a lighter soup. Just add more veggies to keep it hearty and filling.
Different Flavor Profiles
