A fast and easy Instant Pot spaghetti recipe that cooks in just 10 minutes, combining pasta and sauce in one pot for a flavorful, comforting meal perfect for busy weeknights.

Ingredients

Scale
  • 8 ounces spaghetti, broken in half (regular or gluten-free)
  • 1 tablespoon extra virgin olive oil
  • 3 cloves garlic, minced
  • 1 small onion, finely chopped (about ½ cup)
  • 1 (14.5-ounce) can diced tomatoes
  • 1 cup tomato sauce
  • 1 teaspoon Italian seasoning (oregano, basil, thyme mix)
  • 1 teaspoon salt, adjust to taste
  • ½ teaspoon freshly ground black pepper
  • 2 cups water or broth (vegetable or chicken)
  • ¼ teaspoon red pepper flakes (optional)
  • 1 teaspoon balsamic vinegar
  • Parmesan cheese, freshly grated for serving

Instructions

  1. Set Instant Pot to ‘Sauté’ mode and heat olive oil. Add minced garlic and chopped onion, stirring frequently until softened and fragrant, about 3 to 5 minutes. Avoid burning the garlic.
  2. Cancel ‘Sauté’ mode. Add canned diced tomatoes, tomato sauce, Italian seasoning, salt, black pepper, red pepper flakes (if using), and balsamic vinegar. Stir gently to combine.
  3. Break spaghetti in half and layer in a crisscross pattern over the sauce without stirring. Pour broth or water over the top, ensuring noodles are mostly submerged.
  4. Seal Instant Pot lid and set valve to ‘Sealing.’ Select ‘Manual’ or ‘Pressure Cook’ on high for 8 minutes. Allow time for pressure to build before countdown.
  5. When cooking finishes, perform a quick pressure release by turning valve to ‘Venting.’ Open lid carefully away from you. Stir spaghetti gently to combine sauce and noodles.
  6. Taste and adjust seasoning if needed. Serve hot with freshly grated Parmesan cheese and an optional drizzle of olive oil.

Notes

Layer spaghetti on top of sauce and liquid without stirring to prevent sticking. Use quick pressure release to avoid overcooking pasta. If sauce is too thin after cooking, use ‘Sauté’ mode to simmer and thicken. Adjust seasoning after cooking as pressure cooking can mute flavors slightly.
