Instant Pot Spaghetti is one of those weeknight dinners that feels almost magical. With just one pot and minimal prep, you can create a hearty, comforting meal that tastes like it simmered all day. The Instant Pot takes classic spaghetti and turns it into a fast, hands-off recipe that fits perfectly into busy schedules without sacrificing flavor. Everything cooks together, allowing the pasta to absorb the rich tomato sauce while the beef becomes tender and well-seasoned.

Why You’ll Love This Recipe

There are plenty of reasons to love Instant Pot Spaghetti, starting with how easy it is. Everything cooks in one pot, which means fewer dishes and less cleanup. The pressure cooker infuses the flavors deeply, giving you rich, savory spaghetti in a fraction of the time it would take on the stovetop.

This recipe is also incredibly flexible. You can easily adjust the seasonings, swap proteins, or add vegetables depending on what you have on hand. The optional cream cheese adds a subtle creaminess that balances the acidity of the tomatoes, creating a smooth and comforting sauce. Best of all, this recipe delivers consistent results, making it perfect for busy weeknights, meal prep, or feeding a crowd.

Ingredients You’ll Need

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Each ingredient in this Instant Pot Spaghetti plays an important role in building flavor and texture. Olive oil helps brown the beef and prevents sticking, while garlic powder, onion powder, and Italian seasoning add classic Italian-inspired flavor without extra prep. Ground beef provides heartiness, and the combination of marinara sauce and diced tomatoes creates a rich, balanced tomato base.

Spaghetti cooks directly in the sauce, absorbing all those savory flavors as it softens. Chicken broth adds depth and helps prevent burning during pressure cooking. The optional cream cheese may seem unexpected, but it melts into the sauce beautifully, adding body and a gentle creaminess that takes the dish to the next level.

Let’s Get Started

Set the Instant Pot to the Sauté function and add the olive oil. Once hot, add the ground beef. Cook until browned, breaking it apart with a spoon as it cooks.
Season the beef with garlic powder, onion powder, Italian seasoning, salt, and pepper. Stir well so the seasonings coat the meat evenly.
Turn off the Sauté function and carefully drain excess grease if needed.
Break the spaghetti noodles in half and layer them over the beef in a crisscross pattern. This helps prevent clumping during cooking.
Pour the marinara sauce over the pasta, followed by the undrained diced tomatoes and chicken broth. Do not stir. Keeping the liquid on top helps prevent the Instant Pot from triggering a burn warning.
Secure the lid and set the valve to Sealing. Cook on High Pressure for 8 minutes.
Once cooking is complete, allow a quick pressure release.
Remove the lid and gently stir the spaghetti. Add the softened cream cheese if using, stirring until fully melted and incorporated.
Let the spaghetti rest for a few minutes to thicken before serving.

Servings and Pairing Variations

Instant Pot Spaghetti is satisfying on its own, but it pairs wonderfully with a variety of sides. Garlic bread, cheesy breadsticks, or a simple green salad with vinaigrette balance the richness of the pasta. Roasted vegetables like broccoli or zucchini make excellent additions for a more complete meal.

For variations, try swapping ground beef for ground turkey or Italian sausage. You can also add sliced mushrooms, bell peppers, or spinach for extra nutrition. If you enjoy spice, a pinch of red pepper flakes adds heat without overpowering the dish.

Storage Tips

Allow leftovers to cool completely before storing. Transfer spaghetti to an airtight container and refrigerate for up to 4 days. When reheating, add a splash of water or broth to loosen the sauce and warm gently on the stovetop or in the microwave.

Instant Pot Spaghetti can also be frozen, though the texture of the pasta may soften slightly. Freeze in portion-sized containers for up to 2 months. Thaw overnight in the refrigerator before reheating.

FAQs

Can I use a different type of pasta?

Yes, but cooking times may vary. Thicker pastas like penne or rotini may need an additional minute or two under pressure.

Why shouldn’t I stir before pressure cooking?

Stirring can cause the pasta to sink and stick to the bottom, which may trigger a burn warning. Layering helps prevent this.

Is cream cheese necessary?

No, but it adds richness and smoothness to the sauce. You can skip it or substitute a splash of heavy cream.

Can I double the recipe?

Yes, as long as you do not exceed the Instant Pot’s maximum fill line.
