Instant Pot Hamburger Helper

Brown the Ground Beef:

Press the “Sauté” function key. Select a temperature with the “Adjust” key for “Normal”. When Instant Pot reaches the given working temperature, it displays “Hot” and you can start sautéing.
Heat one tablespoon oil in a skillet. Cook the ground beef undisturbed for about 1-2 minutes, then turning and keep cooking until brown.
Don't forget to keep scraping the bottom of the pot so nothing sticks on it to prevent burning. Transfer to a plate and set aside.

Saute the Seasoning Ingredients:

Add onion into the pot and cook until translucent, stir in garlic, chili powder, ground mustard, smoked paprika, Italian seasoning (or oregano), Worcestershire sauce, black pepper, salt, sugar.
Then turn off the "Sauté" by pressing "Keep Warm"

Pressure Cooking:

Add the browned ground beef and one cup of beef broth, stir until combined.
Be sure to scrape the bottom of the pot so nothing sticks on it to prevent burning.
Add pasta and the remaining of the broth (2 cups of broth). Make sure that the pasta is cover with the liquid by pressing gently but DO NOT STIR!
Place the lid and ensure the valve is in the “Sealing” position.
Set to "Manual" setting and cook for 5 minutes with quick release. Remove the lid and select "Cancel". Season with additional salt and pepper if needed.
Note: If you find the pasta is still too tough for your liking, you can close the lid and set the pressure cooker to "Manual", and set timer to "O", then do a quick release after the pressure cooking is done.

Add Milk, Cheese and Corn Starch:

In a mixing bowl, stir in one tablespoon of corn starch with 2 cups of milk. Add the milk mixture into the pot, add cheese and slowly stir until combined.
Serve and enjoy.
