Description
A hearty, low-carb casserole inspired by Philly cheesesteaks, featuring tender steak, sautéed peppers and onions, and a creamy cheese sauce topped with melty provolone—all without the bread.
Ingredients
1 lb (450 g) thinly sliced sirloin or ribeye steak
1 tbsp olive oil
1 tbsp butter (optional)
1 large onion, thinly sliced
2 bell peppers (green and red), thinly sliced
8 oz (225 g) mushrooms, sliced (optional)
2 cloves garlic, minced
4 oz (115 g) cream cheese, softened
1/2 cup beef broth (low-sodium preferred)
1 tbsp Worcestershire sauce
1 tsp Italian seasoning
1/2 tsp smoked paprika
Salt and black pepper, to taste
8 slices provolone cheese
Instructions
- Preheat oven to 375°F (190°C).
- Pat steak dry, season with salt and pepper, and sear in a skillet with olive oil (and butter if using) for 1–2 minutes per side. Transfer steak to a plate.
- In the same skillet, sauté onion and bell peppers with a pinch of salt for 4–5 minutes.
- Add mushrooms (if using) and cook for 2–3 more minutes.
- Stir in garlic and cook for 30 seconds.
- Reduce heat to medium-low and stir in cream cheese, beef broth, Worcestershire sauce, Italian seasoning, and smoked paprika until sauce is smooth.
- Return steak and juices to the skillet and toss to coat.
- Transfer everything to a greased 9×13-inch (23×33 cm) baking dish and top with provolone slices.
- Bake for 10–12 minutes until cheese is melted and casserole is bubbling.
- Broil for 1–2 minutes for golden spots on top if desired.
- Rest casserole for 5 minutes before serving.
Notes
Slice steak thinly against the grain for tenderness.
Sauté vegetables thoroughly to avoid excess moisture.
Can be made ahead and refrigerated before baking.
Serve over cauliflower rice or zucchini noodles for a full low-carb meal.
Substitute provolone with mozzarella or white American cheese if preferred.
