Low-Carb Philly Cheesesteak Casserole

Ingredients

1 lb ground beef

1 tablespoon olive oil

1 onion, sliced

1 bell pepper, sliced

1 teaspoon garlic powder

1 teaspoon onion powder

½ teaspoon smoked paprika

Salt and pepper, to taste

4 oz cream cheese, softened

1 cup shredded provolone cheese

1 cup shredded mozzarella cheese

2 tablespoons heavy cream

Fresh parsley, chopped (optional, for garnish)

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

Directions

Preheat your oven to 375°F (190°C).

In a large skillet, heat the olive oil over medium heat. Add the ground beef and cook until browned, breaking it apart with a spoon as it cooks.

Add the sliced onion and bell pepper to the skillet. Cook for 5-7 minutes, or until the vegetables are softened.

Season with garlic powder, onion powder, smoked paprika, salt, and pepper. Stir to combine and cook for another 2-3 minutes.

In a separate bowl, mix together the softened cream cheese, provolone cheese, mozzarella cheese, and heavy cream until smooth.

Add the cheese mixture to the beef and vegetable mixture, stirring well to combine.

Transfer the entire mixture into a greased 9x9 baking dish and spread it out evenly.

Bake in the preheated oven for 20-25 minutes, or until the casserole is bubbly and golden on top.

Garnish with fresh parsley if desired, and serve hot.

Storage/Reheating

Storage: Store any leftovers in an airtight container in the refrigerator for up to 3 days.
