This Philly Cheesesteak Casserole transforms the flavors of the classic sandwich into a hearty, low-carb family dinner. Loaded with seasoned ground beef, sautéed peppers and onions, melted provolone cheese, and a rich egg custard, it’s cheesy, satisfying, and incredibly easy to make.

Ingredients

• 1½ lb ground beef
• 2 bell peppers, chopped

• 2 teaspoons minced garlic

How to Make Philly Cheesesteak Casserole

1. Preheat the oven to 350°F (175°C). Grease a 9×9-inch baking dish.
2. Heat a large skillet over medium-high heat and begin browning the ground beef.
3. When the beef is partially browned, add the chopped bell peppers and onion.
4. Cook until the beef is fully browned and the vegetables have softened slightly.
5. Stir in the minced garlic and seasoned salt. Cook for 30 seconds until fragrant.
6. Drain the beef mixture thoroughly to remove excess grease.
7. Transfer the meat and vegetable mixture to the prepared baking dish and spread evenly.
8. Arrange the provolone cheese slices evenly over the top.
9. In a small bowl, whisk together the eggs, heavy cream, and Worcestershire sauce.
10. Pour the egg mixture evenly over the casserole.
11. Bake for 35–40 minutes, or until set and golden brown on top.
12. Let rest for 5–10 minutes before slicing and serving.
