Ingredients

Scale
  • 8 ounces spaghetti pasta (broken in half to fit the pot)
  • 2 tablespoons olive oil
  • 1 pound ground beef or Italian sausage (optional)
  • 1 medium yellow onion, finely chopped
  • 3 large garlic cloves, minced
  • 1 can (28 ounces) crushed tomatoes (San Marzano recommended)
  • 1 can (8 ounces) tomato sauce
  • 3 cups chicken or vegetable broth (low sodium preferred)
  • 1 cup small-curd cottage cheese
  • ½ cup freshly grated Parmesan cheese
  • 1 teaspoon Italian seasoning (oregano, basil, thyme blend)
  • ¼ teaspoon red pepper flakes (optional)
  • Salt and black pepper to taste
  • Fresh basil or parsley for garnish (optional)

Instructions

  1. Set Instant Pot to sauté mode and heat olive oil. Add chopped onion and garlic, sauté for about 3 minutes until softened and fragrant.
  2. Add ground beef or sausage if using, break up with spoon and cook until browned (about 7 minutes). Drain excess fat if necessary.
  3. Pour in crushed tomatoes and tomato sauce. Stir in Italian seasoning, red pepper flakes, salt, and pepper. Mix well.
  4. Break spaghetti in half and layer evenly over the sauce without stirring. Pour broth gently over pasta to cover as much as possible.
  5. Seal Instant Pot lid and set to manual high pressure for 8 minutes. Allow time to come to pressure.
  6. Quick release pressure carefully. Open lid and gently stir pasta; sauce may appear saucy but will thicken.
  7. Stir in cottage cheese and Parmesan until sauce is creamy and coats spaghetti.
  8. Taste and adjust salt or pepper if needed. Garnish with fresh basil or parsley before serving.

Notes

[‘Do not stir pasta before cooking to prevent sticking.’, ‘Use small-curd cottage cheese for a silky texture.’, ‘Quick release pressure carefully to avoid burns.’, ‘Brown meat well for deeper flavor.’, ‘Adjust seasoning after adding cheese to avoid over-salting.’, ‘Add a splash of broth or water if sauce is too thick.’, ‘Leftovers keep well refrigerated for 3-4 days and freeze up to 2 months.’]
