Instant Pot Spaghetti and Meat Sauce

Spaghetti night usually means boiling water, juggling two pans, and scrubbing pots later.
This version? Everything cooks together in the Instant Pot—meat, pasta, and sauce—so you get a full, cozy dinner with almost zero cleanup.

Save for Later!

Instant Pot Spaghetti and Meat Sauce brings all the comfort of the stovetop classic, but with a hands-off twist. You brown the meat right in the pot, pour in the sauce and noodles, and then let the pressure do its thing. It takes just 8 minutes of cook time and comes out saucy, flavorful, and ready to eat as soon as the lid comes off.

It’s the kind of weeknight win we rely on. No draining. No splatter. Just one pot of good food, ready when you are.

How to Make It in the Instant Pot

The process is simple but strategic. You want to layer things in a way that avoids clumping or burning, and once you’ve done it, it becomes second nature.

• Sauté the beef – Use the sauté setting on the Instant Pot to brown the ground beef with chopped onion and garlic. Drain excess fat if needed.
• Deglaze the pot – Pour in a splash of broth or water and scrape up any browned bits with a wooden spoon.
• Add pasta and sauce – Break the spaghetti in half and layer it over the meat in crisscrossed bundles. Pour in the sauce and broth. Gently press everything down without stirring.
• Seal and pressure cook – Lock the lid, set to high pressure, and cook for 8 minutes. Use quick release when done.
• Stir and finish – Stir well to combine the sauce and pasta. If needed, let it sit for a few minutes to thicken.
• Serve with toppings – Add Parmesan, red pepper flakes, or basil to taste.

That’s it—spaghetti night made easy.

How to Store and Reheat It

Spaghetti with meat sauce always makes great leftovers. The flavors soak in more overnight, and it holds up well for days.

Storing Leftovers

Let everything cool completely before transferring to airtight containers. Store in the fridge for up to 4 days, or freeze for up to 2 months.

Reheating Tips

• Microwave: Reheat in 30–45 second intervals, stirring and adding a splash of broth or water if it’s thick
• Stovetop: Reheat in a covered pan over medium-low heat with a bit of water to loosen it up
• Instant Pot (Reheat function): Great for larger leftovers, just stir halfway through to heat evenly

The sauce may thicken as it sits, but a little liquid brings it right back.

Instant Pot Spaghetti FAQ

Can I use another type of pasta?

Yes, just adjust the cook time slightly—most pastas need about half their regular cook time under pressure. Penne, linguine, or rigatoni all work well.

Do I have to use ground beef?

Nope. You can swap it with ground turkey, pork, sausage, or even lentils if you want a meatless version.

Why shouldn’t I stir before pressure cooking?

Stirring can cause the pasta to clump or stick to the bottom. Layering prevents burning and ensures even cooking.

What if my sauce is too thin after cooking?

Let it sit on “Keep Warm” for 5–10 minutes to thicken, or stir in a small handful of grated cheese to tighten it up.

Can I double the recipe?

Yes, if your Instant Pot is 8 quarts or more. Just don’t fill past the max line and avoid stirring before sealing.
