If you’re looking for a weeknight dinner that’s ridiculously simple, budget-friendly, and still packs in the veggies, this Instant Pot veggie pasta is your new go-to. It’s one of those “dump, stir, and walk away” meals — perfect for busy nights or when you just can’t deal with complicated cooking.

Ingredients You’ll Need for Instant Pot Veggie Pasta
-

-
1 jar (about 24 oz) of your favorite store-bought pasta sauce
-
2–3 cups chopped vegetables (bell peppers, zucchini, mushrooms, celery, carrots, or whatever you have on hand)
-
1 medium onion, chopped
-
2–3 garlic cloves, minced
-
2–3 cups water or broth (adjust based on pasta shape/absorption)
-
2 tablespoons nutritional yeast (optional, for cheesy flavor)
-
1 teaspoon Italian seasoning (optional, for extra flavor)
-
1 tablespoon olive oil (optional, for sautéing)
-
Salt and pepper to taste
Optional Add-ins for Variety
-
1 can drained chickpeas or white beans (protein boost)
-
1 block firm tofu, cubed (stirred in after cooking)
-
A handful of fresh spinach or kale (added after pressure cooking)
-
Vegan Parmesan or cashew cream (for richness)
Step-by-Step Instructions
1. Sauté the Aromatics
Turn the Instant Pot to sauté mode. Add olive oil (if using), then toss in chopped onion and garlic. Cook for 2–3 minutes until fragrant. Add vegetables and sauté another 2–3 minutes to soften them slightly.
2. Add Pasta & Sauce
Cancel sauté mode. Add pasta, pasta sauce, water/broth, nutritional yeast, and Italian seasoning. Stir gently to combine, ensuring pasta is submerged.
3. Pressure Cook
Close the lid and set the Instant Pot to manual high pressure for half the pasta’s package cooking time (example: if the box says 10 minutes, set to 5 minutes).
4. Quick Release
When the timer beeps, carefully do a quick release. Open the lid and stir well.
5. Adjust & Serve
Check pasta tenderness. If the sauce seems thick, add a splash of water or broth. Taste and adjust seasoning. Garnish with fresh herbs or vegan Parmesan. Serve warm.
Tips & Variations
-
Healthier pasta – Use whole wheat or lentil-based pasta for extra fiber and protein.

-
Spicy twist – Use arrabbiata sauce or add red pepper flakes.
-
Extra protein – Add beans, tofu, or even plant-based sausage slices.
-
More greens – Stir in spinach, kale, or broccoli florets after cooking.
-
Kid-friendly version – Use mild marinara, skip the chili flakes, and add sweeter veggies like corn and peas.
