How to Make Low Carb Philly Cheesesteak Casserole

Ingredients:

2 lbs ground beef (80/20 fat ratio preferred)
1 large onion (diced)
2 large bell peppers (green, red, or mixed, diced)
2 cloves garlic (minced)
8 oz cream cheese (softened to room temperature)
2 tbsp Worcestershire sauce
Salt and pepper (to taste)
8 oz provolone cheese (sliced)
1.5 cups mozzarella cheese (shredded)
1 tbsp olive oil

Directions:

Preheat your oven to 350°F (175°C) and spray a 9×13 baking dish with non-stick spray.
Heat olive oil in a large skillet over medium heat.
Add diced onions and bell peppers to the hot oil, cooking for 5-6 minutes until they start to soften and become fragrant.
Add minced garlic and cook for another 30 seconds, stirring constantly to prevent burning.
Add ground beef to the skillet, breaking it up with your spatula as it cooks. Season generously with salt and pepper, cooking for 7-8 minutes until completely browned with no pink remaining. Drain excess fat if needed.
Stir in Worcestershire sauce and let it coat the meat mixture for enhanced flavor. Reduce heat to low and add the softened cream cheese, stirring until completely melted and creamy.
Transfer the mixture to your prepared baking dish and spread evenly. Layer torn provolone pieces over the beef, then top with shredded mozzarella for that perfect cheese pull.
Bake for 22-25 minutes until cheese is melted, bubbly, and lightly golden on top. Let rest for 5 minutes before serving to allow flavors to meld together.

How to Serve Low Carb Philly Cheesesteak Casserole

Serve this casserole hot, right out of the oven. It’s great on its own but can also be paired with a side salad or steamed veggies for a complete meal. You can also dish it up with some fresh herbs like parsley or basil on top for added freshness and flavor.

How to Store Low Carb Philly Cheesesteak Casserole

If you have leftovers, store them in an airtight container in the refrigerator. The casserole will keep well for about 3-4 days. To reheat, simply place it in the oven at 350°F (175°C) until warmed through or microwave it until hot.

Tips to Make Low Carb Philly Cheesesteak Casserole

Use ground beef with a higher fat content for a juicier dish.
Feel free to add mushrooms or other veggies for extra flavor and nutrition.
Make sure to let it rest before serving. This helps the flavors blend and makes it easier to serve.

Variation

You can switch up the cheeses if you prefer. Cheddar or Monterey Jack can work great as substitutes for provolone and mozzarella. You can also use turkey or ground chicken if you want a leaner option for the meat.
