Turn on your Instant Pot and select the Saute mode on high.
Add olive oil, onions and ground beef. Saute until onions are soft and beef is mostly cooked, about 3-5 minutes.
Add garlic. Continue to saute for an additional 2 minutes.
Select the 'Cancel' button to reset the cooking function. Add beef broth and quickly deglaze the bottom of the pot with a non-stick spatula or spoon to ensure no brown bits or onions are stuck to the bottom of the pot. This will help ensure you avoid the 'BURN' notice.
Add salsa and pasta shells. Gently press the pasta shells down into the broth ensuring they are mostly overed with liquid.
Lock the lid in place and select the 'Pressure Cook' fucntion on high. Cook for 3 minutes.
Once the timer beeps, quick release the steam and carefully remove the lid.
Add cream cheese, shredded cheese, Italian seasoning, garlic pepper and salt to taste. Still well until all incredients are well combined.
Serve hot and enjoy!
