The Ingredients

This recipe uses simple, flavorful ingredients that come together beautifully.

For the Meatballs:

Ground beef – 1 pound (or a mix of beef and pork)
Breadcrumbs – ½ cup (Italian-style if available)
Grated Parmesan cheese – ½ cup
Egg – 1 large, lightly beaten
Garlic – 2 cloves, minced
Italian seasoning – 1 teaspoon
Salt and pepper – to taste

For the Sauce and Spaghetti:

Olive oil – 1 tablespoon (for browning)
Marinara sauce – 1 jar (24 ounces)
Water or beef broth – 3 cups
Spaghetti – 12 ounces, broken in half
Fresh basil or parsley – for garnish (optional)
Extra Parmesan – for serving

Step-by-Step Instructions

Step 1: Make the Meatballs

In a large bowl, combine the ground beef, breadcrumbs, Parmesan cheese, egg, garlic, Italian seasoning, salt, and pepper. Mix until just combined — be careful not to overwork the meat. Roll the mixture into 1- to 1½-inch meatballs (about 16–18 meatballs).

Step 2: Brown the Meatballs (Optional but Recommended)

Set the Instant Pot to Sauté mode. Add the olive oil and heat until shimmering. Brown the meatballs in batches, turning them so all sides are browned, about 2–3 minutes per side. Remove the meatballs to a plate and set aside.

Step 3: Deglaze the Pot

Pour the water or beef broth into the pot and use a wooden spoon to scrape up any browned bits from the bottom. This step is essential to prevent a “Burn” warning.

Step 4: Layer the Ingredients

Return the meatballs to the pot, arranging them in a single layer. Break the spaghetti in half and place it over the meatballs in a crisscross pattern to prevent clumping. Pour the marinara sauce evenly over the top. Do not stir — layering is the key to preventing clumpy pasta.

Step 5: Pressure Cook

Close the Instant Pot lid, set the valve to “Sealing,” and pressure cook on HIGH for 8 minutes. When the cooking time is complete, carefully perform a quick release by turning the valve to “Venting.”

Step 6: Stir and Serve

Open the lid and gently stir everything together to combine the sauce, spaghetti, and meatballs. If the sauce seems too thin, let it rest for 2–3 minutes to thicken. Serve immediately, garnished with fresh basil or parsley and extra Parmesan cheese.

How to Serve It Like a Pro

This spaghetti and meatballs is delicious on its own, but a few simple additions make it even better:

With garlic bread – For soaking up every last bit of sauce.
With a side salad – A crisp green salad cuts through the richness.
With extra Parmesan – A final sprinkle adds savory depth.
With red pepper flakes – For those who like a little heat.
With fresh basil – Adds brightness and color.
With a glass of red wine – The perfect pairing.
With a sprinkle of parsley – Adds freshness.
With a side of roasted vegetables – Broccoli or zucchini add color and nutrition.

Variations & Swaps

One of the best things about this recipe is how flexible it is. Here are some easy ways to make it your own:

Make It with Frozen Meatballs – For an even quicker meal, use frozen meatballs. Place them in the bottom of the pot, add the spaghetti, sauce, and water, and pressure cook for 8 minutes.
Make It with Different Meat – Use ground turkey, chicken, or a mix of beef and pork instead of beef.
Make It with Different Pasta – Use any pasta shape — penne, rigatoni, or fettuccine — instead of spaghetti.
Make It with a Spicy Kick – Add red pepper flakes to the sauce for heat.
Make It with Extra Vegetables – Add sautéed mushrooms, bell peppers, or spinach.
Make It with Cheese-Stuffed Meatballs – Add a cube of mozzarella in the center of each meatball.
Make It Gluten-Free – Use gluten-free breadcrumbs and pasta.
Make It with a Thicker Sauce – Let the dish rest for a few minutes after cooking.
