When you need an easy, light lunch, this Instant Pot Vegetable Soup recipe is ideal! Packed with veggies and and herb-flavored broth, the flavors hit all the right notes. Don't have an Instant Pot? Not problem! Stovetop instructions are also included.
To keep the prep time a minimum, I used a frozen vegetable mix, which I typically keep stocked in our freezer for quick meals.
The stovetop works just as well for making this soup (the instructions are included below), but the Instant Pot is even more hands off. Sauté the onion and garlic, then throw in the rest of the ingredients. Let the pressure cooker do its thing.
So quick and easy!

Substitutions and Additions
▪️ VEGETABLES: Feel free to play around with other frozen vegetables, such as zucchini, cauliflower and potatoes.
▪️ BROTH: Use chicken broth if preferred. However, the soup will no longer be vegetarian or vegan.
▪️ HERBS: Dried rosemary or Italian seasoning also work well in this soup.
▪️ GRAINS: Stir in some cooked grains at the end. I keep cooked whole grains in the freezer for this reason! Cook up batches once a month and stash them in portion-sized packages in the freezer. See Instant Pot Quinoa, Instant Farro and Instant Pot Sorghum.
How to make Vegetable Soup
Vegetable Soup (Instant Pot instructions)
SAUTÉ: Set your Instant Pot to the SAUTÉ mode, then drizzle in a little olive oil. Add the onion and cook, stirring occasionally, until the onion softens. That should takea bout 5 minutes. Add the garlic, oregano and thyme. Cook for 1 minute.

ADD THE REST: Pour in the vegetable broth, canned diced tomatoes, frozen vegetables, salt and pepper.
