Gather These Items

To craft this delightful casserole, you’ll need the following ingredients:

2 lbs ground beef (80/20 fat ratio preferred): This ensures a juicy texture.
1 large onion (diced): For that sweet and savory flavor.
2 large bell peppers (green, red, or mixed, diced): Choose your favorites for color and taste.
2 cloves garlic (minced): Garlic elevates the flavor.
8 oz cream cheese (softened to room temperature): This creates a creamy texture.
2 tbsp Worcestershire sauce: A secret ingredient for depth of flavor.
Salt and pepper (to taste): Essential seasonings.
8 oz provolone cheese (sliced): The classic cheesesteak cheese.
1.5 cups mozzarella cheese (shredded): For that delicious, gooey top.
1 tbsp olive oil: Used for sautéing.

Feel free to substitute ground turkey or chicken if you prefer!

Directions to Follow

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 begin to soften and become fragrant.
Stir in minced garlic, cooking for another 30 seconds—keep stirring to prevent burning.
Add ground beef to the skillet, breaking it up with your spatula as it cooks. Season 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 to enhance the flavor, then reduce the heat to low and add the softened cream cheese. Stir until completely melted and creamy.
Transfer the beef mixture to your prepared baking dish and spread it evenly.
Layer torn provolone cheese over the beef, followed by shredded mozzarella for that perfect cheese pull.
Bake for 22-25 minutes until the cheese is melted, bubbly, and lightly golden on top.
Let it rest for 5 minutes before serving to allow the flavors to meld together.

Serving Suggestions

Once your casserole is baked and ready, consider these creative ways to enjoy it:

Serve with a simple green salad drizzled with balsamic vinaigrette to balance the richness.
Pair it with steamed broccoli or roasted cauliflower for an additional low-carb side.
For a fun twist, consider tortilla chips or lettuce wraps for a unique serving experience!

Storage and Reheating Tips

Refrigeration: Store any leftover casserole in an airtight container in the fridge for up to 4 days.
Freezing: You can also freeze the casserole for later use! Just portion it out and wrap tightly with plastic wrap and foil. It should last about 2-3 months in the freezer.
Reheating: When you’re ready to enjoy it again, reheat in the oven at 350°F (175°C) until warmed through, or microwave in individual portions.
