Step 1

Turn the Instant Pot on "SAUTE." Add in the olive oil, chopped onion, and garlic. Cook for about 3 minutes, until onions are translucent. Add in ground beef and cook until crumbled and brown, with no pink remaining. Drain out any excess grease.

Step 2

Add in the beef broth, scraping the bottom of the pot with a wooden spoon until no bits remain (this is called deglazing). Then add in the water, tomato sauce, diced tomatoes, worcestershire sauce, Italian seasoning, salt, pepper, and pasta noodles. Stir until combined.

Step 3

Lock the lid in place and and set the pressure valve to "SEALING." Select "HIGH PRESSURE" for a cook time of 2 minutes. When cook time ends, do a CONTROLLED quick pressure release (see notes below).

Step 4

Remove the lid and stir. Add in the shredded cheese and ENJOY!
