Turn on your Ninja Foodi and select the sauté function.
Add oil and heat for 1 minute and then add the onion and cook until the onion becomes tender and translucent.
Season beef with salt and pepper and then add to the Ninja Foodi and brown on all sides.
Add the garlic, Worcestershire sauce, and soy sauce, and then stir in the mushrooms.
Stir in flour being sure to coat the meat and mushrooms evenly.
Pour in beef broth and stir. Be sure to stir well, scraping the bottom of the pot to deglaze it. You don’t want any burnt-on pieces of beef or onions stuck to the bottom of the pot. ***If you are using a non-stick pot, use a silicone or wooden spoon to deglaze the pot.
Close the lid and pressure cook at high pressure for 18 minutes with the valve on “seal.” When the timer beeps, delay the release of pressure for 5 minutes.
Open the lid, stir, and add in the egg noodles and then close the lid and pressure cook on high pressure for 5 minutes with the vent on “seal.” When cooking pasta in the Ninja Foodi, feel free to modify the pasta from the recipe. The trick is to look at the cooking times on the box. Whatever the box says- cut it in half and subtract 2 minutes. So, if the box says to cook for 10 minutes, you will cut that in half (5) and subtract 2. All together you would cook for 3 minutes.
When the timer beeps, allow pressure to naturally release for 5 minutes. Open the lid and add ½ cup of sour cream and stir.
