Ingredients

  • 3 cups cubed London Broil steak
  • 2 teaspoons Montreal Steak seasoning blend
  • Salt to taste
  • 1 tablespoon vegetable oil
  • 1 onion diced
  • 1 teaspoon minced garlic
  • 3 pounds baby red potatoes cut into 1 to 2 inch pieces
  • 10.6 oz can cream of mushroom soup
  • 1 cup sour cream
  • 1 & 1/2 cup shredded sharp cheddar cheese divided

Instructions

  • Preheat the oven to 350 degrees. Prepare a 9x13 casserole dish with nonstick cooking spray.
  • Season the steak cubes with steak seasoning and salt.
  • In a large skillet over medium-high heat, pour the oil and heat until hot. Add the steak and brown on all sides. The meat does not need to be cooked through.
  • Add the onion to the skillet and cook until soft and caramelized. Stir in the garlic.
  • In a large bowl, stir together the browned steak and onions, potatoes, soup, sour cream, and 1 cup cheese.
  • Transfer the mixture to the prepared casserole dish. Top with the remaining cheese.
  • Bake for 1 hour, uncovered, or until the potatoes are tender. If the cheese begins to brown, tent the casserole with aluminum foil.
