Ingredients You’ll Need

For this recipe, you’ll need the following:

  • Ground Beef – You can saute this with your Italian sausage in the Instant Pot but to save time, you can also cook the two meats ahead of time and store them in the refrigerator or freezer until you are ready to make your spaghetti. If you do this you’ll need about 6 ounces of cooked ground beef.
  • Ground Italian sausage – Like the beef the measurements in the recipe are based on cooking the meat in your Instant pot. If you want to save time and pre-cook the sausage you’ll need about 7 ounces of cooked sausage.
  • Seasonings – You’ll need garlic powder, onion powder, and Kosher or regular salt.
  • Spaghetti – We use regular spaghetti for this, not the thin variety.
  • Water – You only need 8 ounces or just about a cup of water to make the spaghetti. 
  • Rao’s marinara – That’s our favorite, but you can use your preferred brand or make your own homemade version if you like.

Instructions

sauteing meat for Instant Pot Spaghetti

Step 1 – Saute the meat. Use your 6 Quart Instant Pot’s SAUTE function to brown the beef and sausage. As it cooks, add the garlic powder, onion powder, and salt. You’ll need to make sure it is cooked through.

When it has finished cooking, drain the excess grease from the pot by pouring the meat through a strainer. Once the meat is drained, place it back in the pot.

Step 2 – Prep the spaghetti. You’ll need to break the spaghetti in half and add them on top of the cooked meat. As you lay it down, fan out the ends so that they are less likely to clump together when cooking.

Step 3 – Pour in the water and sauce. Without stirring the ingredients, pour the water and then the pasta sauce over the noodles. Again, DO NOT STIR!! Just make sure the liquid completely covers the pasta by pushing down on it as needed. 

Step 4 – Cook the pasta. Lock the lid in place and turn the valve to SEALING. Once in place, set the pot to HIGH pressure for 8 minutes. When the timer goes off, carefully do a quick release to let out the pressure. 

Step 5 – Prep and serve. Once the pin drops, carefully remove the lid and stir the pasta. If there are any clumps, use a fork to gently comb through and separate the pasta. Finally, stir the meat sauce, and pasta together and then set the lid on top and let sit for 5 more minutes before serving hot from the pot.

Tip for best results. Once the timer has gone off and you’ve opened the lid, use a fork to stir everything around. You may find some noodles that are clumped together – this is normal! Use the fork to gently comb through them and pull them apart. Stir the pasta together with the sauce and meat until you don’t find any more pasta clumps. Finally, sit the lid back on the pot and let the spaghetti sit for 5 more minutes to ensure everything is perfectly cooked and any excess liquid is absorbed.

How Long Does it Take to Cook Spaghetti Noodles in an Instant Pot?

Regular sized spaghetti noodles only take about 6 to 8 minutes of cooking time in the Instant Pot. This does not count the 5 to 10 minutes it takes to come up to pressure. The total time you can expect them to take is about 11 to 18 minutes with the pressure time included.

If you want to save time you can brown the ground beef and Italian sausage ahead of time. The cooked weights are approximately 6 ounces of cooked ground beef and 7 ounces of cooked Italian sausage. I like to make a double batch so I have enough for my lasagna stuffed peppers and this easy pressure cooker spaghetti during the week. 

How Much Liquid Do You Cook Pasta in the Instant Pot?

You need about 2 cups of liquid for every 8 ounces of spaghetti. Our recipe uses a combination of water and marinara sauce, which counts towards the liquid needed. 

A general rule of thumb, though this is not always perfect, you need enough liquid to just barely cover the noodles. And another rule of thumb is you need at least 1 cup of liquid for the Instant Pot to come up to pressure.

What to Serve With It

Spaghetti in an Instant Pot makes a great family dinner or lunch. It goes great with rolls, Cheese Twists, or homemade Texas Toast.

Of course, it also pairs great with salads and greens. We love serving spaghetti with our Panzanella Salad Italian Bread Salad or our Italian Green Bean Salad. Both are great and tasty options for as sides.

How to Make it Ahead of Time 

This is a very quick and easy recipe to make just about any night of the week. We recommend making it fresh and serving it immediately. 

If you have leftovers, you can store them in a sealed container in the fridge for about 3 to 4 days.

To reheat add 1 cup of sauce and then microwave for 3 to 5 minutes, stirring halfway through. You could also place leftovers in a pot with 1 additional cup of pasta sauce and heat over medium heat, stirring often, until warmed through.
