⭐ How to Make Low-Carb Philly Cheesesteak Casserole
1. Preheat the Oven
Preheat oven to 350°F (175°C). Spray a 9×9-inch baking dish with non-stick spray.
2. Cook the Beef & Vegetables
Heat a large skillet over medium heat. Add ground beef and cook, breaking it apart as it browns.
When beef is mostly cooked but still slightly pink, add diced bell peppers, onion, garlic, and seasoned salt. Continue cooking until beef is fully cooked and vegetables are tender.
Drain excess grease.
3. Assemble the Base
Transfer the beef and vegetable mixture evenly into the prepared baking dish.
Tear provolone cheese into small pieces and scatter evenly over the beef mixture.
4. Mix the Egg Custard
In a mixing bowl, whisk together:
- Eggs
- Heavy cream
- Worcestershire sauce
- Hot sauce (if using)
Pour evenly over the beef and cheese layers.
5. Bake
Bake uncovered for 35 minutes, or until the eggs are fully set and the top is lightly golden.
6. Rest & Serve
Remove from oven and let rest for 5 minutes before slicing and serving.
💡 Tips for Best Results
- Provolone gives the most authentic cheesesteak flavor, but mozzarella or white American also work well
- Let the casserole rest before cutting to help it set cleanly
- For extra cheesiness, add another slice of provolone on top during the last 5 minutes
🔄 Variations
- Extra Philly-Style: Add sautéed mushrooms
- Spicy: Use pepper jack cheese or add sliced jalapeños
- Dairy-Light: Reduce cheese and increase egg custard slightly
