Ingredients

Scale
  • 3 to 4 medium russet potatoes, peeled and thinly sliced
  • 1 pound thinly sliced ribeye or sirloin steak
  • 8 ounces provolone cheese, sliced or shredded
  • 1 cup thinly sliced bell peppers (mix of green and red recommended)
  • 1 medium yellow onion, thinly sliced
  • 2 cloves garlic, minced
  • 2 tablespoons butter
  • 1 cup beef broth
  • 1/2 cup milk or half-and-half
  • 2 tablespoons flour
  • Salt and pepper to taste
  • Optional: pinch of crushed red pepper flakes

Instructions

  1. Peel and thinly slice 3-4 medium russet potatoes (about 1/8 inch thick). Rinse slices under cold water to remove excess starch, then pat dry with paper towels.
  2. Heat 2 tablespoons butter in a large skillet over medium heat. Add sliced onion and bell peppers; cook, stirring occasionally, until softened and slightly caramelized, about 7-8 minutes. Stir in minced garlic and cook for 30 seconds until fragrant. Remove veggies from skillet and set aside.
  3. In the same skillet, add thinly sliced steak. Season with salt and pepper. Cook over medium-high heat until browned but not fully cooked through, about 3-4 minutes. Remove steak and set aside with veggies.
  4. Lower heat to medium. Melt 2 tablespoons butter in skillet. Whisk in flour and cook for 1-2 minutes to form a roux. Slowly add beef broth and milk, whisking to avoid lumps. Simmer until thickened, about 3-4 minutes. Season with salt, pepper, and red pepper flakes if using.
  5. Preheat oven to 375°F (190°C). In a 9×13-inch baking dish, layer half the potatoes evenly. Top with half the steak, half the veggies, half the provolone cheese, and half the sauce. Repeat layers with remaining ingredients.
  6. Cover casserole with foil and bake for 40 minutes. Remove foil and bake uncovered for an additional 15 minutes or until potatoes are tender and cheese is bubbly and golden.
  7. Let casserole rest for 5-10 minutes before serving to allow layers to set.

Notes

If sauce is too thick before pouring, add a splash more broth or milk to loosen. If potatoes are not tender after baking, cover and bake for an extra 10 minutes. Thinly slice potatoes for even cooking and pat dry after rinsing to prevent clumping. Cook steak quickly to keep it tender. Cover casserole during initial baking to trap steam and uncover later to crisp cheese topping.
