If you ask me, the Instant Pot is one of the best things to happen to weeknight dinners.
This classic comfort food comes together in one pot with hardly any effort on your part. Tender meatballs and perfectly cooked spaghetti sit in a rich tomato sauce that tastes like you spent hours in the kitchen.
The spaghetti cooks right in the sauce with the meatballs, so all those flavors blend together beautifully. A sprinkle of Parmesan cheese and Italian seasoning at the end brings everything together.
It’s a family-friendly meal that takes about 20 minutes from start to finish, perfect for those busy nights when you need something filling and satisfying.

What Kind of Meatballs Should I Use?
You’ve got plenty of options when it comes to meatballs for this Instant Pot recipe. Frozen meatballs are super convenient and work perfectly – just toss them in straight from the freezer without thawing. If you prefer homemade, you can use your favorite meatball recipe, whether that’s classic beef, a beef and pork blend, turkey, or even chicken meatballs. Store-bought refrigerated meatballs from the meat section are another great choice if you want something quick but not frozen. Just keep in mind that the size of your meatballs matters – smaller ones (about 1 inch) will cook faster and more evenly than larger ones, so try to keep them relatively uniform in size.
Options for Substitutions
This recipe is pretty forgiving when it comes to swapping ingredients:
- Meatballs: You can use frozen meatballs, homemade ones, or even swap them for Italian sausage links cut into chunks. Turkey or chicken meatballs work great too if you’re looking for a lighter option.
- Spaghetti: Any long pasta like linguine, fettuccine, or angel hair will work here. Just keep in mind that thicker pasta might need an extra minute or two of cooking time. Break the pasta in half so it fits better in the Instant Pot.
- Pasta sauce: Use whatever you have on hand – marinara, tomato basil, or even a jar of arrabbiata if you like some heat. You can also make a quick sauce from a can of crushed tomatoes with some Italian seasoning.
- Parmesan: Romano cheese, Pecorino, or even a good melting mozzarella will work if you’re out of Parmesan. In a pinch, skip the cheese altogether and the dish will still taste good.
- Water: You can replace some or all of the water with chicken or vegetable broth for extra flavor, but water works just fine and keeps things simple.
Watch Out for These Mistakes While Cooking
The biggest mistake people make with Instant Pot pasta is not adding enough liquid, which can trigger the dreaded burn notice – make sure your water and sauce completely cover the noodles before sealing the lid.
Another common error is arranging the spaghetti in a crisscross pattern instead of laying it in the same direction, which causes the noodles to clump together and cook unevenly.
Don’t skip the quick release step, as letting the pressure release naturally will overcook your pasta into mush, and always give everything a good stir immediately after opening the lid since the noodles on the bottom cook faster than those on top.
If your sauce seems too thin after cooking, simply switch to sauté mode for a few minutes to thicken it up before serving.
What to Serve With Spaghetti and Meatballs?
A simple side salad with Italian dressing is my go-to when serving spaghetti and meatballs – it adds a nice fresh crunch to balance out the hearty pasta. Garlic bread is another obvious choice that everyone loves, and it’s perfect for mopping up any extra sauce left on your plate. If you want to add some vegetables to the meal, roasted broccoli or sautéed green beans with garlic work really well alongside the pasta. You could also serve it with a Caesar salad or some roasted zucchini if you’re looking to keep things on the lighter side.
Storage Instructions
Store: Keep your leftover spaghetti and meatballs in an airtight container in the fridge for up to 4 days. The pasta will soak up some of the sauce as it sits, so you might want to add a splash of water or extra sauce when you reheat it.
Freeze: This freezes really well for up to 3 months. Let it cool completely first, then portion it into freezer-safe containers. I like to freeze individual servings so I can grab just what I need for a quick dinner.
Reheat: Warm it up in the microwave with a damp paper towel over the top to keep the pasta from drying out, or reheat on the stovetop over medium-low heat with a bit of extra water. Stir occasionally until it’s heated through, and top with fresh Parmesan before serving.

Ingredients
- 1 lb meatballs (I use Rosina brand for the best texture)
- 10 oz spaghetti (snapped in half to prevent clumping)
- 28 oz pasta sauce (I prefer Rao’s Homemade for the best flavor)
- 3 cups water
- 1 tbsp olive oil
- 1/4 cup parmesan
- 1/2 tsp garlic powder
- 1/2 tsp Italian seasoning
Step 1: Prepare the Instant Pot and Layer the Base
- 1 tbsp olive oil
- 1 lb meatballs
- 10 oz spaghetti, snapped in half
Pour the olive oil into your Instant Pot and add the meatballs in a single, even layer on the bottom.
This helps them cook evenly and prevents sticking.
Snap the spaghetti in half and arrange it directly over the meatballs in a crosshatch pattern—snapping it prevents the long strands from clumping together during cooking.
Step 2: Build the Cooking Liquid and Season
- 28 oz pasta sauce
- 3 cups water
- 1/2 tsp garlic powder
- 1/2 tsp Italian seasoning
Pour the pasta sauce and water directly over the spaghetti and meatballs, stirring gently to distribute evenly and ensure the noodles are submerged.
Sprinkle the garlic powder and Italian seasoning over the mixture—I like to season at this stage so the flavors infuse into the liquid as everything cooks together.
The total liquid should cover the pasta by about an inch.
Step 3: Cook Under Pressure
Seal the Instant Pot lid and set the valve to sealing position.
Cook on high pressure for 10 minutes.
The intense heat will cook the pasta perfectly while the meatballs stay tender, and everything will absorb the flavors of the sauce.
Step 4: Release Pressure and Combine
Once the timer beeps, carefully switch the valve to venting to quick-release all pressure.
Remove the lid and stir the pasta and meatballs together gently, breaking up any clumps that may have formed.
The pasta should be al dente and the sauce should coat everything evenly.
Step 5: Finish and Serve
- 1/4 cup parmesan
- cooked pasta and meatballs from Step 4
Transfer the pasta and meatballs to serving bowls or plates.
Top generously with parmesan cheese and fresh basil if desired.
The residual heat will help the cheese melt slightly into the sauce for a creamy finish.
