How to Make Instant Pot Spaghetti

Instant Pot Spaghetti with Meatballs. Served with bread.

The key to perfect Spaghetti in the Instant Pot is to add the ingredients to the pressure cooker in a specific order!

We love Spaghetti and Meatballs, so adding a layer of meatballs to this dish was a must for our family.

STEP 1: Turn on Instant Pot and select “SAUTE.” Add olive oil and garlic to Instant Pot and cook for about 2 minutes.

STEP 2: Select “CANCEL.” Add frozen meatballs in a single layer to the bottom of the Instant Pot. I actually added a couple extra on top of the single layer and it turned out great.

STEP 3: Add thin spaghetti noodles (that are broken in half so they fit) on top of the meatballs. Drizzle with extra olive oil to prevent sticking.

STEP 4: Pour one jar of marinara sauce over the top of the noodles, then add water. Finally, sprinkle in extra seasoning…salt, Italian Seasoning, and red pepper flakes.

Fill your empty jar of marinara sauce (24oz size) with water. This equals the 3 cups water you’ll need, and you are getting every last drop of sauce out of the jar!

STEP 5: Lock lid in place, turn knob to “SEALING“, select HIGH PRESSURE and cook time of 9 minutes. When cook time ends, do a quick pressure release.

STEP 6: Stir gently to combine sauce with noodles and meatballs. Sprinkle with parmesan cheese and fresh parsley. ENJOY

TIPS FOR Instant Pot Spaghetti and Meatballs

  • Homemade Meatballs or store bought frozen meatballs both work great! I prefer having them frozen so they don’t fall apart.
  • I’ve used several kinds of pasta in this recipe, and they all turn out wonderful. Don’t skip the extra olive oil.
  • Choosing a flavorful marinara sauce is a must. We love Rao’s Marinara as it’s sugar free yet packed with flavor!
  • 1 jar of marinara sauce (24oz) is also 3 cups of water…just fill your empty jar with water and dump it in!
  • DO NOT STIR before pressure cooking. Add the ingredients in the order above, but do NOT stir.
  • I use Quick Release for this recipe so that my noodles don’t overcook.
  • When you open the lid after pressure cooking, it may appear watery. NOW you stir and let it sit for a minute, it will come together nicely.

Can you make meat sauce instead of meatballs

Yes. Absolutely. In Step 1 above, add ground beef or turkey to Instant Pot with the garlic and olive oil. Cook until browned and drain out any excess grease. 

Be sure to scrape the excess bits off the bottom of the Instant Pot so you don’t get the dreaded “burn” notice!

Return the meat to the bottom of the Instant Pot and continue with Step 3. ENJOY.

    I will try this, but 9 minutes is like triple the time it takes to cook spaghetti, unless you like it to be very overcooked.

    Angie I have never heard of any spaghetti brand or any pasta for that matter that takes 3 minutes to cook. Usually it’s anywhere from 7-11 minutes. Where have you seen pasta that takes 3 minutes to cook?
