Why You’ll Love It:

Low-Carb Option: By skipping the sandwich roll, you get all the flavors of a Philly cheese steak in a lower-carb, keto-friendly version.
Family-Friendly: With its creamy, cheesy texture and mild flavors, it’s a dish even picky eaters will love.
Adaptable: Feel free to customize it with different cheeses, veggies, or spices for a personalized touch.
Key Ingredients:
Lean Ground Beef: Opt for a leaner cut (90/10) to keep the casserole from becoming greasy, though you can also use ground turkey if you prefer.
Bell Peppers: Traditional Philly cheese steak usually includes green bell peppers, but feel free to mix it up with red, yellow, or orange peppers for a sweeter, colorful twist.
Onion: Yellow onion adds sweetness and depth, though red onion would add a milder, slightly different flavor.
Provolone Cheese: Known for its creamy melt and mild flavor, Provolone is classic in Philly cheesesteaks, but mozzarella or even a cheddar blend can work if you’re looking for a stronger flavor.
Heavy Cream and Eggs: These give the casserole its fluffy, rich texture, similar to a quiche or frittata. They also help bind the ingredients together.
Seasonings: Seasoned salt adds an extra depth of flavor, while Worcestershire sauce lends a subtle umami and savory taste. A dash of hot sauce is optional but brings a slight kick that complements the richness of the dish.

Storage and Meal Prep Tips:
Refrigeration: Store leftovers in an airtight container in the refrigerator for up to 3-4 days. Reheat individual portions in the microwave for a quick meal.
Freezing: This casserole is also freezer-friendly! Portion it into individual servings, wrap tightly in plastic wrap or place in an airtight container, and freeze for up to 2 months. Thaw in the fridge overnight before reheating.
Reheating: To maintain its creamy texture, reheat in the oven at 300°F (150°C) for about 15 minutes, or microwave on medium heat until warmed through.
Variations:
Keto Philly Cheese Steak Casserole: This casserole is already quite low in carbs, but to make it even more keto-friendly, you could skip the onion or use a small amount of onion powder to cut carbs.
Mushroom Philly Cheese Steak: Add sliced mushrooms to the vegetable mixture for a meatier texture and extra flavor.
Cheesy Twist: Use a mix of Provolone and mozzarella for extra cheesiness, or try sharp cheddar if you prefer a more intense cheese flavor.
Turkey or Chicken Option: Swap out ground beef for ground turkey or shredded rotisserie chicken for a lighter, yet still hearty, take on the recipe.
Spicy Philly: For a spicier version, add diced jalapeños to the vegetable mix or sprinkle a pinch of red pepper flakes into the egg mixture.
Cauliflower Philly: To lower the calories and carbs, replace half the ground beef with chopped cauliflower, which blends in seamlessly with the beef and adds extra fiber.
