Ingredient Notes
- Veggie stock - you can use store bought veggie stock, or homemade vegetable stock. Swap for turkey stock, or bone broth - any of these options will work!
- Kidney beans - can be swapped for your favorite fully cooked beans; chickpeas, white beans or black beans will all work!
- Diced tomatoes - for added flavor, consider adding flavored diced tomatoes such as fire-roasted, garlic + herb, or even Rotel for a kick
- Cauliflower - fresh or frozen cauliflower can be used, but try to stick to 1 inch or smaller cauliflower florets; some frozen cauliflower is too large to eat in soup.
- Nutritional yeast - is a deactivated yeast that boosts the flavor of the soup; you can swap for parmesan cheese
Other Vegetables You Can Add
- broccoli
- green beans- add after cooking
- corn or peas (fresh or frozen)- add after cooking
- parsnips
- kale or spinach- add after cooking
- potatoes or sweet potatoes- cut into ½ inch cubes
- squash
- leeks- sauté with onions (or in place of onions)
Keep in mind that changing the veggies may alter the cooking time; use your best judgment to determine when the vegetables are soft enough to eat.
Step by Step directions
Sauté Onions & Garlic
Select the 'sauté' function of the Instant Pot. Add the olive oil and onions to the stainless steel inner pot, and sauté for 5-7 minutes, until they are soft and translucent.

Make a space in the middle of the onions, then add the garlic. Cook for 1 minute, stirring until it is fragrant and cooked through.
Combine
Add the carrots, celery, cauliflower florets, zucchini, basil, oregano, salt, bay leaf, diced tomatoes, vegetable stock, kidney beans, and nutritional yeast. Stir and scrape the bottom of the pan to make sure nothing is stuck.
TIP- it's a good idea to deglaze the bottom of your Instant Pot after sautéing to avoid triggering the burn warning.
Cook
Put the lid on the Instant Pot and set the valve to the 'sealing' position. Pressure cook on high pressure for 5 minutes. When the cooking cycle has completed, allow the pot to naturally release for 10 minutes before carefully transitioning the valve to the 'venting' position, releasing all remaining pressure.
Serve
Remove bay leaf. Serve with bread or crackers.
FAQ

Meal Prep Tips
This Instant Pot vegetable soup is the perfect recipe to add into your meal prep routine! You can meal prep it in two different ways:
- cook ahead and reheat- cook a big batch of this stew on the weekend and reheat for easy lunches or dinners. We like storing the cooked stew in a 2 cup glass meal prep containers or a meal mug.
- assemble ahead but don't cook - as a crockpot freezer meal (find 34 more crockpot freezer meals here!)
- combine all ingredients in a large freezer bag, a large meal prep container or a reusable silicone bag
- freeze for up to 3 months
- when you are ready to cook, thaw completely and cook as directed (skipping the sauté steps)
Storage + Reheating
- Fridge- cool completely, then cover the pot, or portion out into air-tight storage jars. Refrigerate for up to 4 days.
- Freezer- cool completely, then portion out into glass or plastic freezer jars. Leave ¼ of the jar empty to account for expansion, and leave lids ajar until the soup is fully frozen. Freeze for up to 3 months.
- Thaw - overnight in the fridge (speed the process by leaving on the counter for a few hours, or by immersing the jar in water).
- Reheat - Heat individual servings in the microwave until steaming hot. Heat larger portions in a pot over medium heat on the stove for 15-20 minutes, until warmed through.
