Ingredients
  

  • 2 tablespoons olive oil
  • 6 cloves garlic
  • 6 ounce tomato paste
  • 1 tablespoon balsamic vinegar
  • 1 teaspoon Italian seasoning
  • 1/2 teaspoon Sea Salt
  • 1/4 teaspoon Black Pepper
  • 1/4 teaspoon Crushed Red Pepper Flakes optional
  • 1 14 ounce Diced Tomatoes
  • 5 cups Vegetable Stock
  • 1 lb rigatoni pasta gluten free if GF

Instructions
 

  • Add all the ingredients to the inner pot of the Instant Pot.  Make sure to stir well with a wooden spoon.
  • Set Instant Pot to Pressure Cook/High Pressure for 5 minutes. Once finished, quick pressure release the remaining steam, taking care not to have your hands or face near the pressure valve vent.
  • Once float valve has lowered, carefully open the lid. Stir the pasta well to combine the pasta sauce, rigatoni, and all ingredients. Place the lid back on, turn the Instant Pot off for 5 minutes for pasta to soak up the last of the sauce before serving.
  • Top with fresh basil, black pepper, or parmesan cheese before serving. Refrigerate leftovers in an airtight container for up to 2 days.
