Most minestrone is made with pasta, beans and vegetables. This vegetarian version cooks quickly thanks to the Instant Pot (affiliate link) and is made gluten-free by swapping dry green lentils for the pasta. It makes a nice light main course meal thanks to the addition of protein- and fiber-rich lentils.

Step 4: Place the lid on the pot in the locked position and move the steam release valve to “Sealing” position. Cook on HIGH pressure for 5 minutes.

Step 5: After the cooking time finishes, allow a natural pressure release for 10 minutes before moving the steam release valve to “Venting” position and releasing the pressure (being careful to not get burned from the steam).

Step 6: Unlock and remove the lid once the float valve drops.

Step 7: Add salt and give mixture a good stir. Adjust seasonings as desired.

Recipe Notes

Classic minestrone is usually made with vegetables, pasta and sometimes beans. This enlightened version is made gluten-free by substituting dry green lentils for the pasta.

According to the recipe instructions, it is best to add the salt after the lentils have become tender, rather than before cooking. If you add salt before cooking, the lentils may turn out tough, not soft and tender.

Serving Suggestions

Enjoy this soup plain (without any additional toppings), or garnished with fresh chopped Italian flat-leaf parsley, fresh chopped basil or freshly grated or shaved Parmesan cheese. (Be sure to adjust WW Points accordingly when making any adjustments.)

A nice thick slice of toasted crusty bread makes a nice accompaniment.

Ways to Use Leftovers

Leftover soup can be store in the refrigerator in an airtight container. You may find it necessary to add a little more water (or vegetable broth (affiliate link)) when reheating leftovers to achieve your desired consistency.

For added fiber and protein, you can stir in some beans (white, cannellini, pinto, black, etc.) and/or chopped, or shredded, cooked chicken breast.

Stirring in a little prepared basil pesto to each bowl of reheated soup is another nice flavorful addition.
