A comforting and easy-to-make casserole that captures the classic Philly cheesesteak flavors with layers of tender ribeye, sautéed veggies, and melted provolone cheese. Perfect for family dinners, potlucks, or game days.

Ingredients

Scale
  • 1 pound ribeye steak, thinly sliced
  • 8 ounces provolone cheese, sliced or shredded
  • 1 large white onion, thinly sliced
  • 1 medium green bell pepper, thinly sliced
  • 2 garlic cloves, minced
  • 2 tablespoons unsalted butter
  • 1/4 cup mayonnaise
  • 1/2 cup milk (whole or 2%)
  • 3 large eggs, room temperature
  • 1 tablespoon Worcestershire sauce
  • Salt and black pepper, to taste
  • 1 teaspoon Italian seasoning
  • 3 cups cubed French bread or hoagie rolls (day-old preferred)

Instructions

  1. Thinly slice the ribeye steak against the grain into bite-sized strips. Slice the onion and green bell pepper thinly. Mince the garlic cloves. Cube the bread into roughly 1-inch pieces and set aside.
  2. Heat 1 tablespoon of butter in a skillet over medium heat. Add onions and bell peppers and cook until soft and slightly caramelized, about 5-6 minutes. Stir in garlic and cook for another minute until fragrant. Transfer veggies to a bowl and set aside.
  3. In the same skillet, add remaining butter and increase heat to medium-high. Add sliced ribeye in a single layer and cook until browned but still juicy, about 5-7 minutes. Season with salt, pepper, and 1 teaspoon Worcestershire sauce while cooking. Remove from heat.
  4. In a large bowl, whisk together eggs, milk, mayonnaise, Italian seasoning, remaining Worcestershire sauce, salt, and pepper until smooth.
  5. Grease a 9×13-inch baking dish lightly. Spread half of the bread cubes evenly on the bottom. Layer half of the cooked steak, half of the sautéed veggies, and half of the provolone cheese. Repeat layers once more, finishing with cheese on top. Pour the egg mixture evenly over everything, pressing gently so the bread absorbs the liquid.
  6. Let the casserole sit for 15 minutes at room temperature to soak up flavors. Preheat oven to 350°F (175°C). Bake uncovered for 35-40 minutes, or until the top is golden and bubbly and a knife inserted in the center comes out clean.
  7. Let the casserole rest for 5 minutes before slicing and serving.

Notes

If the top browns too quickly, tent with foil halfway through baking. Use thin slices of steak for tenderness and quick cooking. Letting the casserole rest before baking helps the bread absorb the custard and prevents sogginess. Use day-old bread cubes for best texture. Room temperature eggs and milk help create a smooth custard base.
