Start by adding the frozen meatballs to the bottom of the Instant Pot Bowl.
Then add the beef broth, Worcestershire sauce, minced garlic, Italian seasoning, salt, and pepper, to the pot.
Spread the egg noodles on top of the meatballs.
Secure the lid on top of the Instant Pot, ensuring that the vent is in a sealed position.
Then set the manual high pressure for 3 minutes.
When the time is up, do a quick release.
When the time is up, open the lid (do not force the cover open) when the pin drops, and you can easily open the Instant Pot. Open and stir the pasta.
Mix in the half and half and cornstarch. Mix well.
Plate, serve and enjoy!
