Description

A quick and easy Instant Pot spaghetti recipe featuring cooked green lentils for added protein and fiber, combined with vegan marinara sauce for a hearty, flavorful meal that’s perfect for busy weeknights.


Ingredients

Scale

Main Ingredients

  • 2 tablespoons olive oil
  • 1/2 onion, diced small
  • 2 cloves garlic, minced
  • 3/4 teaspoon salt
  • 2 cups cooked green lentils
  • 2 cups water
  • 8 ounces spaghetti
  • 1 jar (25.5 ounces) vegan marinara sauce


Instructions

  1. Sauté aromatics: Press the sauté button on the Instant Pot. When hot, add the olive oil, diced onion and minced garlic. Cook, stirring, for about 3 minutes until the onion is translucent.
  2. Add lentils and salt: Stir in the salt and cooked green lentils. Mix well, then turn off the sauté function.
  3. Deglaze and add pasta: Pour in the water and use a spatula to deglaze the bottom of the pot, scraping up any stuck bits to avoid the burn warning. Break the spaghetti noodles in half and add them to the pot.
  4. Add marinara sauce: Pour the vegan marinara sauce over the noodles and gently push the noodles down into the liquid to submerge, but do not stir.
  5. Pressure cook: Secure the lid on the Instant Pot, seal the valve, and set to cook at high pressure for 9 minutes.
  6. Release pressure and serve: Perform a quick release to prevent the pasta from overcooking. Open the lid, stir everything together, and serve immediately. Optional: top with vegan parmesan cheese and serve with bread for a complete meal.

Notes

  • This recipe has not been tested with gluten-free spaghetti, but it is likely to work well as a substitute.
  • If you don’t have pre-cooked lentils, you can make your own by cooking 1 cup uncooked green lentils with 3 cups of water on the stovetop, bringing to a boil then simmering for about 30 minutes before draining.
  • Use vegan parmesan cheese and fresh bread as optional topping and sides to enhance the meal.
