Cook time Cook time: 3 minutes

Instant Pot Spaghetti is cooked in a hearty, homemade marinara packed with beef, herbs, and juicy tomatoes. You can have this ready in less than 15 minutes!

The Instant Pot is PERFECT for fast and delicious family meals like this. Let the IP take the guesswork out of your menu with this Instant Pot Country Style Ribs, Instant Pot Pork Stew, and Instant Pot Meatloaf and Mashed Potatoes!

Pressure Cooker Spaghetti

Instant Pot Spaghetti will completely change the way you make this beloved dish! For one, raw pasta only takes 3 MINUTES to cook in the IP, which means you can have dinner done in less than 30 minutes (or less if you simply dump all the ingredients and skip the sautéing part.

Next, we’re making a simple, hearty marinara from scratch to complement the pasta. To turn it into a hearty meal, we’re adding ground beef but you can definitely add whatever meat you have on hand or not include it at all for a vegetarian version.

Finally, everyone loves spaghetti! This will be a highly-requested dish in your home, and a serious lifesaver during busy weeks or when you have no idea what to cook. Most importantly, it always turns out perfect and delicious.

Can I use the instant pot to cook homemade spaghetti?

Yes, and it’s one of the easiest and tastiest ways to cook spaghetti! The IP cuts down cooking time in minutes while infusing the pasta with so much flavor. Furthermore, everything happens in one pot, so less clean-up, too!

Ingredients needed:

  • Spaghetti: About a pound of dried pasta.
  • Chicken stock: You can also use water, beef broth, or veggie broth. 
  • Sauce: For a simple marinara, prep some diced tomatoes, onion, and fresh garlic (both diced), herbs (basil, oregano, Italian blend, plus parsley), soy sauce, and Worcestershire.

How to make the best homemade IP spaghetti

  1. Brown and season. First, turn on the IP’s Sauté, and wait until it says “Hot.” Then dump in your beef, stir-fry until brown, then add the aromatics and herbs. Continue stir-frying until well-mixed and fragrant. Then, pour a cup of stock and scrub off all the brown bits stuck to the bottom. These are huge flavor boosters, so don’t skip this part!
  2. Assemble. Pour the rest of your broth along with the Worcestershire plus your soy sauce. Then, break the spaghetti in half and submerge in the broth. DON’T MIX! Finally, dump a can of tomatoes/marinara on top in a single layer.
  3. Cook. Pressure-cook for 3 mins. on High, then leave alone for 5 mins. to naturally vent pressure. Then, unseal the vent to finish.
  4. Thicken, then season. At this point, the pasta sauce will look thin. Simply turn on “Sauté”
     again, and simmer until thick. Finally, add as much seasoning as you like.
  5. Serve. Plate up with more fresh basil, parmesan, and enjoy!

Recipe variations and substitutions:

  • Other meats: Combined beef and pork, use chicken or turkey for a lighter version, or even lamb if you wish. You can also use plant-based minced alternatives if you like.
  • Add bacon, sausage, etc.: Turn it into a meatier, heartier dish with cubed bacon, crumbled sausages, ham, and other flavored or cured meats.
  • Spicy: Love heat? Add a dash of chili flakes or cayenne.
  • Other pasta: This will work with any type of pasta! Use fettuccine, macaroni, ziti, or whatever you wish, and simply adjust cooking time as needed. 
  • Include vegetables: Add finely chopped carrots, stir in some kale or spinach, add grated zucchini, cubed eggplants, mushrooms, etc.
  • Creamier: Stir in some double cream, a bit of sour cream, or a little cream cheese. 

Frequently Asked Questions

How long is the cooking time for making spaghetti in the Instant Pot?

Cooking spaghetti in the IP is one of the quickest methods, hands down. In this recipe, it only takes 3 minutes of pressure cooking.

Can cooking spaghetti sauce in the IP burn it?

Yes, it can burn. This is why you should deglaze the stuck brown bits completely, or it will give you a burn notice. Next, make sure to arrange the layers properly. You want the raw pasta ON TOP, with the tomatoes/marinara above that, and the liquid on the bottom so it doesn’t burn.

Finally, follow the cook times exactly so the food doesn’t dry out and start to burn.

What to serve with homemade instant pot spaghetti?

How to store leftovers?

You can store the leftovers two ways, by freezing or in the fridge. Make sure to cool them completely first, then follow these steps:

  • Fridge storage: Place in an air-tight container, then store in the cool part of the fridge for up to 3 days.
  • Freezer storage: Place in a freezer-safe, tightly-sealed container then freeze. Store it for up to a month.

To reheat, defrost it overnight or on the counter first if doing so from frozen. Then, microwave until hot. You can also heat it up in the skillet with a little more marinara.

Recipe tips:

  • Don’t skip the deglazing part! Those stuck, browned bits add SERIOUS FLAVOR to the sauce.
  • Instead of broth, you can also deglaze with some red wine. 
  • You can turn this into a dump-and-go meal! Just layer the stock, minced meat, and aromatics on the bottom, pasta on top, then sauce on top of that. Follow cook times, and you’re done!
  • You can use store-bought marinara, or use our delicious homemade version.
