Instant Pot Spaghetti and Meatballs
A quick and easy one-pot spaghetti recipe with ground meat that cooks in the Instant Pot, melding flavors for a delicious weeknight meal.
I make this Instant Pot spaghetti on busy weeknights when everyone wants something warm, fast, and familiar — and it delivers every time. Browned ground meat simmers right in the sauce with broken spaghetti, so there’s almost no cleanup and the whole family digs in. If you enjoy one-pot dinners that stretch leftovers into lunches, you might also like this slow-cooker comfort meal: Best Crock Pot French Onion Pot Roast.
Why you’ll love this dish
This Instant Pot spaghetti is the definition of weeknight comfort: it’s fast, budget-friendly, and kid-approved. You get the flavors of a traditional spaghetti-and-meat-sauce dinner without babysitting a simmering pot or draining pasta. Because the pasta cooks directly in sauce-plus-water, the flavors meld tightly and you save time on washing extra pots.
When to make it:
- Weeknight dinners when time is tight.
- When you want a hearty, inexpensive meal that feeds a crowd.
- As a base for meals you can repurpose (spaghetti bakes, stuffed peppers, or wraps).
How this recipe comes together
Quick overview of steps so you know what to expect:
- Brown the ground meat using the Instant Pot’s Sauté mode to develop flavor.
- Season the meat briefly, then add marinara and water to create the cooking liquid.
- Add broken spaghetti, push it under the liquid (don’t stir), and pressure-cook.
- Quick-release, stir everything together, finish with Parmesan and herbs.
This approach avoids clumped pasta and keeps the sauce from scorching because everything cooks under pressure rather than simmering on the stove.
What you’ll need
- 1 pound spaghetti (break in half so it fits) — substitute linguine or thin bucatini if desired.
- 1 pound ground beef or turkey — beef gives richer flavor; turkey keeps it lean.
- 1 jar (24 oz) marinara sauce — use your favorite brand or homemade.
- 2 cups water — adds just enough liquid for the pasta to cook through.
- 1 teaspoon garlic powder — or 2 cloves fresh garlic, minced.
- 1 teaspoon onion powder — or 1 small onion, finely chopped.
- Salt and pepper to taste.
- Parmesan cheese for serving.
- Fresh basil or parsley for garnish (optional).
Notes: If you prefer vegetarian, swap the meat for seasoned crumbled tofu or a plant-based ground meat. If you like a thicker sauce, reduce water to 1 3/4 cups, but expect slightly firmer pasta.
Step-by-step instructions
- Turn the Instant Pot to Sauté and let it heat for a minute. Add the ground meat to the pot.
- Cook until the meat is mostly browned and no longer pink, about 4–6 minutes. Use a wooden spoon to break up larger chunks.
- Sprinkle in garlic powder, onion powder, salt, and pepper. Stir to coat the meat and cook 30 seconds to bloom the spices.
- Pour in the marinara sauce and the 2 cups of water. Stir gently to combine and scrape any browned bits from the bottom.
- Break the spaghetti in half and arrange the strands in a crisscross pattern over the sauce. Push the pasta down so it’s submerged, but do not stir. This helps prevent clumping.
- Close the lid, set the valve to sealing, and choose Manual (High Pressure) for 8 minutes.
- When the cook time ends, perform a Quick Release of the pressure according to manufacturer instructions. Open the lid carefully.
- Stir the spaghetti and meat together until the sauce thickens slightly and the pasta softens. Serve hot with grated Parmesan and fresh basil or parsley.
If the pasta seems a touch al dente after stirring, let the pot sit on Keep Warm for 2–3 minutes with the lid ajar to soften further.

Best ways to enjoy it
- Plate with a generous shave of Parmesan and a sprinkle of fresh basil or parsley for color.
- Serve with crusty garlic bread or a simple green salad for contrast.
- For a heartier plate, top with extra cooked meatballs or roasted vegetables.
- Turn leftovers into a baked casserole: place in a baking dish, top with mozzarella, and broil until bubbly.
Pair it with a chilled hibiscus iced tea or a sparkling water with lemon to cut through the richness.
Storage and reheating tips
Refrigerate leftovers in an airtight container within two hours of cooking. Keep for 3–4 days.
To reheat, add a splash of water or sauce to the pasta and warm gently in a skillet over medium heat or in the microwave in 30-second increments, stirring between intervals.
To freeze: cool completely, place in freezer-safe containers or bags, and freeze up to 3 months. Thaw overnight in the fridge before reheating.
Food safety: reheat to at least 165°F (74°C) before serving.
Creative twists
- Italian sausage swap: use ground Italian sausage instead of plain beef for fennel and herb notes.
- Creamy version: stir in 1/4–1/2 cup heavy cream or mascarpone after pressure cooking for a richer sauce.
- Spicy arrabbiata: add 1/2–1 teaspoon red pepper flakes when seasoning.
- Meatball upgrade: form small meatballs, brown them first, then follow the recipe — cook time stays the same.
- Gluten-free: use gluten-free spaghetti and check the sauce label for gluten-free certification. Cooking times may vary by pasta brand.
Your questions answered
Can I use pre-formed frozen meatballs?
A: Yes. Add frozen meatballs to the sauce and water before adding pasta. You may need to extend pressure cook time by 2–3 minutes depending on meatball size; ensure they reach a safe internal temperature.
What if my pasta is mushy after pressure cooking?
A: Overcooking can happen if you use thicker pasta or too much water. Next time reduce the pressure-cook time by 1–2 minutes or lower the water to 1 3/4 cups. For now, serve immediately and avoid using Keep Warm for long periods.
Can I double this recipe?
A: You can double sauce and meat, but avoid doubling pasta — the Instant Pot has a max fill line. If you double everything, use a larger multi-cooker or make two batches for even cooking.
Why did the pot give a burn notice?
A: Burn notices commonly occur if sauce is too thick, there’s little liquid, or bits are stuck to the bottom. Always deglaze after browning (scrape the bottom) and add the water. Don’t stir pasta in before pressure cooking.
