Step 1

Using the saute function of your Instant Pot, cook the ground beef and onions until beef is browned and onions are translucent. Add the garlic and Italian seasoning and cook until fragrant, about 1 minute. Turn off the saute function and drain grease if desired.

Step 2

Add the spaghetti sauce, diced tomatoes and water to the pot. Sprinkle the spaghetti on top, making sure to fan it out so there are no clumps. Press the spaghetti down into the liquid so that most of it is covered (it's OK if some of it pokes out a little bit).

Step 3

Cook on manual (high pressure) for 9 minutes. Quick release, then stir to combine. Season to taste and garnish with basil and grated Parmesan cheese.
