How to Make Instant Pot Spaghetti and Meatballs

This recipe has two main components: the sauce (which you make first and store) and the meatballs with pasta. Do not let the longer ingredient list intimidate you. Once you get into the rhythm of it, the whole thing comes together beautifully.

Step 1: Make the Homemade Tomato Sauce

Set your Instant Pot to Saute. Add the olive oil and butter, and once the butter melts, add the chopped onion. Cook until the onion is golden and caramelized, about 5 minutes. Add the minced garlic and cook for 1 to 2 minutes.

Turn off the Saute function. Add the tomato sauce, stewed tomatoes, tomato paste, and 1 1/2 cups of water. Stir in all the spices and the brown sugar, scraping any bits from the bottom of the liner so nothing burns.

Seal the lid and set the valve to Sealing. Press Manual and cook for 30 minutes. Allow the pressure to release naturally.

Once it has cooled, pour the sauce into jars or a covered container. You will have more sauce than you need for this meal, which is a wonderful thing. Store it in the refrigerator for up to 7 days or freeze it for up to 4 months. Save 2 cups of sauce for the pasta and meatball step.

Step 2: Make the Homemade Meatballs

While the sauce is cooking, get your meatball mixture going. In a large bowl, combine the ground sirloin and ground round. Add all the remaining meatball ingredients except the Ritz crackers. Mix well with clean hands. Add the crushed crackers last so they do not get soggy. This is my key trick for keeping the meatballs juicy and holding together.

Roll the mixture into 2-inch balls and place them on a sheet of waxed paper or foil.

Once your sauce is done and you have rinsed the Instant Pot liner, set the pot to Saute again. Add olive oil and butter. Working in small batches, coat the meatballs in flour (a zip-lock bag and a gentle shake is my favorite method) and brown them on all sides, about 10 minutes per batch. Remove to a plate and repeat until all meatballs are browned and cooked through.

Step 3: Cook the Pasta

Add 1 1/2 cups of water to the Instant Pot and stir, scraping up any browned bits. Add 1/2 cup of tomato sauce and stir again.

Break the spaghetti in half and add it to the pot, stirring to coat as much as possible. Layer the meatballs on top, then pour 1 1/2 cups of sauce over everything. Seal the lid, set the valve to Sealing, and cook on Manual for 6 minutes.

When done, do a quick pressure release. Remove the meatballs and spaghetti to a platter. Stir the remaining sauce in the pot and saute for 4 to 5 minutes to thicken it up. Ladle over the pasta and meatballs, top with grated parmesan, and serve immediately.

Tips for the Best Pressure Cooker Spaghetti and Meatballs

• Do not skip the flour coating on the meatballs. It helps them stay together and gives them a nice crust when browning.
• Ritz crackers are the secret ingredient. The buttery flavor they add to the meatballs is something my family always notices. Other crackers work, but Ritz really is best.
• Make the sauce on the weekend. Since it stores so well, I like to make a big batch on Sunday and use it throughout the week. It makes this weeknight dinner even faster.
• Use two types of ground beef. The sirloin gives you good flavor while the ground round adds a bit more fat, which keeps the meatballs moist. I have tried all-ground-turkey versions and while they work, the original is worth it for a special family dinner.
• Break the spaghetti in half. This is not just for fit. It helps the noodles cook more evenly in the pressure cooker.

Easy Variations to Try

• Short on time? Use a jar of your favorite store-bought marinara and frozen meatballs. The pasta still cooks beautifully in the Instant Pot, and dinner is on the table in about 20 minutes.
• Prefer a meat sauce? Skip the meatballs and brown a pound of Italian sausage on Saute mode, then add the sauce and pasta directly.
• Want a bolognese feel? Add a splash of red wine to the sauce along with an extra tablespoon of tomato paste for a richer, deeper flavor.
• Gluten-free version: Use gluten-free pasta (adjust cook time by 1 to 2 minutes less) and gluten-free crackers in the meatballs.

What to Serve with Instant Pot Spaghetti and Meatballs

This dish is a full meal on its own, but a few good sides make it feel extra special:

• Warm garlic bread or crusty Italian rolls
• A simple green salad with Italian dressing
• Roasted zucchini or steamed broccoli for the kids who need their vegetables (my crew included!)

How to Store Leftovers

Store leftover spaghetti and meatballs in an airtight container in the fridge for up to 4 days. Reheat in the microwave with a splash of water to keep the pasta from drying out, or warm it in a skillet over medium-low heat. The meatballs freeze wonderfully on their own for up to 3 months.

Frequently Asked Questions

Can you cook spaghetti in an Instant Pot without burning?
Yes! The key is making sure the pasta is submerged in enough liquid and that you scrape the bottom of the pot well before sealing. Sticking or burning happens when food residue is left on the bottom from the Saute step. A good scrape with a wooden spoon after adding the water takes care of it.

How long does it take to cook spaghetti in a pressure cooker?
Spaghetti cooks in just 6 minutes at high pressure in an Instant Pot. Add a couple of minutes for the pot to build pressure, and you are looking at about 10 minutes total for the pasta step. The meatball browning and sauce-making take the most time, but those can be done ahead of time to speed things up on a weeknight.

Can I use frozen meatballs in this recipe?
Absolutely. If you want a super quick weeknight dinner, skip the homemade meatball steps and use a bag of frozen Italian-style meatballs. Layer them on top of the pasta just as you would with homemade, and add about 1 to 2 minutes to the cook time to ensure they heat through completely.

Can I double this recipe in an Instant Pot?
You can double the sauce and freeze half for later, which I do regularly. For the pasta step, I would not go beyond a single pound of spaghetti at a time to avoid overflow. If you are feeding a crowd, cook the pasta in two separate batches.

What is the best way to prevent mushy pasta in an Instant Pot?
The most important thing is to do a quick release as soon as the timer goes off. Do not let the pasta sit on Keep Warm or natural release, or it will overcook. Six minutes at high pressure with a quick release gives you perfectly al dente spaghetti every time.
