This Instant Pot Minestrone Soup recipe is an Italian classic made with flavorful pancetta, hearty pasta, and a delicious tomato-based broth. Have this easy soup recipe on the table in just 25 minutes.
Heat olive oil in the Instant Pot on sauté. Once hot, add the pancetta and cook until browned, about 3 minutes. Remove it from the pot onto a plate lined with a paper towel to absorb the excess grease.
Drain the grease from the Instant Pot. Next, add the onion, carrots, celery, zucchini and garlic to the pot and cook for about 4 minutes. Add more oil if necessary. Turn off the pot.
Add in the salt, black pepper, Italian seasoning, bay leaf, orzo, can of diced tomatoes, balsamic vinegar and veggie broth.
Stir to combine, seal and pressure cook on high for 5 minutes.
Quick release the pressure, stir in the pancetta and spinach and let it sit for a few minutes until the spinach is wilted.
Top with grated Parmesan cheese and chopped parsley. Serve with crunchy bread.

Notes
Don't allow a natural pressure release! This soup will overcook and disintegrate if you allow the pressure to naturally release. Always do a quick pressure release immediately once the timer goes off.
I do not recommend freezing minestrone. Soups with pasta in general do not freeze well because the cooked pasta will absorb a majority of the liquid and become overly soft and grainy once defrosted.
Leftover soup can be kept for up to 5 days in the refrigerator. For best results, allow the soup to cool completely, then store in an airtight container.
Leftovers will thicken considerably so add additional broth as needed when reheating to thin the soup back out to your desired consistency.
