  • 2 cups pasta I used penne pasta
  • 1.5 cup water (Half cup for grinding tomato sauce)
  • 3 medium sized tomatoes (around 250gms)
  • 1 red bell pepper
  • 1 carrot
  • 1 small onion around ¼ cup chopped
  • 4 garlic cloves finely chopped
  • ¼ cup cashew cream
  • 1 teaspoon nutritional yeast
  • ¼ teaspoon dried thyme
  • ¼ teaspoon dried oregano
  • pepper powder
  • salt to taste


  • Wash and pat dry tomatoes, red bell pepper. Apply few drops of oil to them and roast them on an open flame.
  • Once these are cooled down a bit, peel the skin of the peppers and tomatoes.
  • Add these peeled tomatoes, bell pepper, chopped carrots to the mixer grinder.
  • Now grind these ingredients into a smooth paste using a half cup of water. This will yield around 2 cups of tomato sauce.
  • Now start an instant pot in sauté mode.
  • Once it is hot, add a teaspoon of oil, chopped garlic, chopped onion, dried thyme, and oregano. You can add fresh herbs if you have them.
  • Let these ingredients fry for a couple of minutes.
  • Now add the tomato bell pepper sauce and a cup of water.
  • Add pepper powder, salt, pasta and mix it well.
  • At this stage, you can taste the water and adjust salt accordingly. Water should taste a little salty.
  • Mix it well and make sure that pasta is submerged completely.
  • Cancel the sauté mode, close the instant pot with the lid and seal it.
  • Now select manual or pressure cook mode and pressure cook on high pressure for four minutes.
  • Once an instant pot beeps, wait for 5 minutes and do a pressure quick pressure release.
  • Open the instant pot and check the pasta for doneness.
  • The pasta will be al dente, and if you like it to be softer, you can pressure cook for five minutes or do a quick pressure release after 10 minutes of cooking.
  • Now add nutritional yeast, cashew cream and mix it once, and the tomato penne pasta is ready to serve!


For every 1 cup of pasta, I use 1 cup of water and half a cup of cooked tomato-based sauce.
