Description

A quick and easy vegan Instant Pot spaghetti recipe featuring green lentils and marinara sauce. This one-pot meal is perfect for busy weeknights, combining protein-rich lentils with perfectly cooked pasta and flavorful sauce in just under 20 minutes.


Ingredients

Scale

Base Ingredients

  • 1-2 tablespoons olive oil
  • 1/2 onion, diced small
  • 2 cloves garlic, minced
  • 3/4 teaspoon salt

Protein and Pasta

  • 2 cups cooked green lentils
  • 8 ounces spaghetti

Liquids and Sauce

  • 2 cups water
  • 1 jar (25.5 ounces) vegan marinara sauce


Instructions

  1. Prepare the base: Press the sauté button on the Instant Pot. When hot, add olive oil, diced onion, and minced garlic. Cook while stirring for about 3 minutes until the onion becomes translucent.
  2. Add lentils and salt: Stir in the salt and cooked green lentils, then turn off the sauté function.
  3. Deglaze and add pasta: Pour in 2 cups of water and use a spatula to scrape the bottom of the pot, releasing any stuck bits to prevent a burn warning.
  4. Layer the spaghetti and sauce: Break the spaghetti noodles in half and add them to the pot. Pour the marinara sauce evenly over the noodles, then gently push the noodles down to ensure they are submerged without stirring.
  5. Pressure cook: Secure the lid, seal the valve, and set the Instant Pot to high pressure for 9 minutes.
  6. Quick release and serve: Perform a quick pressure release to avoid overcooking the pasta. Open the lid, stir everything together thoroughly, and serve. Optionally top with vegan parmesan and accompany with bread.

Notes

  • Gluten free spaghetti has not been tested but is likely to work well in this recipe.
  • Using pre-cooked lentils from the store is convenient; you can find them packaged in the produce section of many grocery stores.
  • If cooking lentils from scratch, use 1 cup uncooked green lentils with 3 cups water, boil then simmer for about 30 minutes. Drain before adding to the recipe.
