📝 About This Recipe

Experience the comforting embrace of a classic Italian-American Sunday dinner in a fraction of the time with this ingenious one-pot pressure cooker method. We start with tender, melt-in-your-mouth meatballs seared to perfection, followed by a rich, aromatic marinara that infuses directly into the pasta strands as they cook. This recipe eliminates the need for multiple pots and strainers, resulting in a velvety, starch-enriched sauce that clings beautifully to every noodle.

🥗 Ingredients

For the Meatballs

  • 1 lb Ground Beef (80/20 blend for best flavor)
  • 1/2 lb Ground Pork
  • 1/2 cup Italian Breadcrumbs
  • 1/3 cup Parmesan Cheese (freshly grated)
  • 1 Egg (large, beaten)
  • 2 tablespoons Fresh Parsley (finely chopped)
  • 1 teaspoon Garlic Powder
  • 2 tablespoons Milk (to keep meatballs moist)

For the Sauce and Pasta

  • 1 lb Spaghetti (broken in half)
  • 24 oz Marinara Sauce (your favorite high-quality jarred or homemade sauce)
  • 3 cups Beef Broth (low sodium)
  • 1/2 cup Yellow Onion (finely diced)
  • 3 cloves Garlic (minced)
  • 2 tablespoons Olive Oil
  • 1 teaspoon Dried Oregano
  • to taste Kosher Salt and Black Pepper

For Garnish

  • 1/4 cup Fresh Basil (torn or chiffonade)
  • as needed Extra Parmesan (for topping)

👨‍🍳 Instructions

  1. 1

    In a large mixing bowl, combine the ground beef, ground pork, breadcrumbs, Parmesan, egg, parsley, garlic powder, and milk. Mix gently with your hands until just combined; do not overwork the meat or the meatballs will be tough.

  2. 2

    Form the mixture into approximately 15-18 meatballs, about 1.5 inches in diameter. Set aside on a plate.

  3. 3

    Turn your Instant Pot to the 'Sauté' setting (High) and add the olive oil. Once the display reads 'Hot', add the meatballs in batches.

  4. 4

    Sear the meatballs for 2-3 minutes per side until a golden-brown crust forms. They do not need to be cooked through. Remove meatballs and set aside on a clean plate.

  5. 5

    In the remaining fat, sauté the diced onion for 3 minutes until translucent. Add the minced garlic and cook for another 30 seconds until fragrant.

  6. 6

    Pour in 1/2 cup of the beef broth and use a wooden spoon to scrape all the brown bits (fond) off the bottom of the pot. This is crucial to prevent the 'Burn' notice.

  7. 7

    Pour in the remaining beef broth and the marinara sauce. Stir in the dried oregano, salt, and pepper.

  8. 8

    Take the broken spaghetti and scatter it into the pot in a 'criss-cross' or 'nest' pattern. Do not just dump it in a pile, or the noodles will stick together in a clump.

  9. 9

    Gently press down on the pasta with a spatula to ensure it is mostly submerged in the liquid, but do not stir.

  10. 10

    Carefully place the seared meatballs on top of the pasta layer.

  11. 11

    Secure the lid and set the valve to the 'Sealing' position. Select 'Manual' or 'Pressure Cook' on High for 8 minutes.

  12. 12

    When the cooking time is up, perform a 'Quick Release' of the pressure immediately to prevent the pasta from overcooking.

  13. 13

    Open the lid and gently stir the pasta and meatballs. The sauce may look thin at first, but it will thicken significantly as it sits for 2-3 minutes and the starch activates.

  14. 14

    Taste and adjust seasoning. Serve immediately garnished with fresh basil and extra Parmesan cheese.

💡 Chef's Tips

To prevent the pasta from sticking, ensure you criss-cross the noodles like a game of Jenga rather than laying them flat. Always deglaze the pot thoroughly after searing meat; those caramelized bits provide flavor but can trigger the overheat sensor. If you prefer 'al dente' pasta, subtract 1 minute from the pressure cooking time. Don't overmix the meatballs; use a light touch to keep them airy and tender. If using leaner meat like turkey, add an extra tablespoon of olive oil to the mix to prevent dryness.

🍽️ Serving Suggestions

Serve with a side of warm, buttery garlic bread to soak up the extra sauce. A crisp, bright Caesar salad provides a refreshing contrast to the rich pasta. Pair with a medium-bodied Italian Chianti or a Zinfandel to complement the acidity of the tomatoes. For a vegetable boost, serve alongside roasted broccolini with lemon zest. Offer a small bowl of red pepper flakes at the table for those who enjoy a bit of heat.
