Ingredients

FOR THE MEAT:

  • 2 Pounds Top Sirloin Steak
  • ½ Teaspoon Garlic Powder
  • ½ Teaspoon Salt
  • ¼ Teaspoon Pepper
  • 1 Large Onion, Sliced
  • 2 Cups Beef Broth

FOR THE CHEESE SAUCE:

  • 4 Tablespoons Butter, Divided
  • 2 Tablespoons Flour
  • ½ Cup Milk
  • 1 Teaspoon Salt
  • ½ Teaspoon Pepper
  • ½ Teaspoon Dijon Mustard, Optional
  • ¼ Teaspoon Hot Sauce, Optional
  • ¾ Cup Shredded Cheddar Cheese
  • 4 Hoagie Rolls, For Serving

Instructions

FOR THE MEAT:

  • *OPTIONAL: For best results, place the steak into the freezer for 30 minutes. This makes thinly slicing the steak easier.
  • Preheat the Instant Pot to Saute.
  • Slice the steak into thin strips and season with garlic, salt, and pepper.
  • Add two tablespoons of the butter to the hot Instant Pot. Add the steak, onion, and peppers and saute, stirring occasionally for 5 minutes.
  • Turn the Instant Pot off. Pour the beef broth into the bottom of the pot and use a wooden spoon to deglaze the bottom of the pot.
  • Place the lid on the pot and set to sealing. Cook on manual/high for 6 minutes.
  • Allow the pot to come to pressure naturally for 10 minutes before removing the lid.

FOR THE CHEESE SAUCE:

  • While the meat is cooking under pressure, heat a medium saucepan on the stove over medium heat.
  • Add the butter and stir until melted. Sprinkle the flour over the butter, cook and stir for 1 minute.
  • Slowly whisk the milk into the flour mixture, turn the heat to low and simmer for about 3 minutes until thick. Whisk in the salt, pepper, dijon mustard, and hot sauce.
  • Remove the pan from the heat and stir in the cheese until melted.
  • Remove the meat from the Instant Pot with a slotted spoon, discarding the broth.
  • Serve the meat mixture in hoagies topped with cheese sauce as desired.
