Ingredients
1 lb ribeye or sirloin steak, thinly sliced
1 red bell pepper, sliced
1 green bell pepper, sliced
1 medium yellow onion, sliced
1 cup mushrooms, sliced
2 cloves garlic, minced
4 oz cream cheese
1/2 cup heavy cream
1 cup shredded provolone cheese
1 cup shredded mozzarella cheese
3 large eggs
1 tbsp olive oil
1/2 tsp salt
1/4 tsp black pepper
1 tbsp butter (for greasing)
Instructions
1. Preheat oven to 375°F (190°C) and grease a 9×13-inch casserole dish.
2. In a large skillet, heat olive oil over medium heat. Sauté onions and bell peppers for 5–7 minutes until softened.
3. Add mushrooms and cook 3–4 minutes more. Stir in garlic and cook until fragrant.
4. Push veggies to the side and sear sliced steak in the same pan until just browned. Season with salt and pepper.
5. In a separate pan or the same skillet (wiped clean), melt cream cheese and heavy cream over low heat. Add half of the provolone and mozzarella until melted into a creamy sauce.
6. In a bowl, mix steak, veggies, and cheese sauce. Beat the eggs and fold them into the mixture.
7. Pour mixture into prepared dish and top with remaining cheese.
8. Bake for 25–30 minutes until bubbly and golden.
9. Let rest 5–10 minutes before serving. Garnish with chopped parsley if desired.
Notes
Chill steak in the freezer for 20 minutes before slicing to make cutting easier.
Letting the casserole rest before slicing ensures clean cuts and better texture.
You can prepare the casserole ahead of time and bake it later for convenience.
