# Instructions:
01 -
Preheat oven to 375°F. Thinly slice 1 large yellow onion, 1 large green bell pepper, 1 large red bell pepper, and 8 oz cremini mushrooms. Mince 4 cloves garlic. This initial prep sets the stage for your delicious Protein-Packed Low Carb Philly Cheesesteak Casserole.
02 -
Heat 2 tbsp olive oil in a large oven-safe skillet over medium-high heat. Add the sliced onion, green bell pepper, red bell pepper, and mushrooms. Sauté for 8-10 minutes until softened and lightly browned. Stir in the minced 4 cloves garlic for the last minute.
03 -
Push vegetables to one side of the skillet. Add 1 1/2 lbs thinly sliced beef to the empty side. Cook for 3-5 minutes, breaking it apart, until browned. Season with salt and pepper to taste. Mix the beef and vegetables together.
04 -
Reduce heat to low. Add 8 oz softened full-fat cream cheese, 1/2 cup low-sodium beef broth, 1 tbsp Worcestershire sauce, 1 tsp onion powder, 1/2 tsp black pepper, and 1/4 tsp red pepper flakes (optional) to the skillet. Stir until the cream cheese is fully melted and a creamy sauce forms, coating the beef and vegetables.
05 -
Taste and adjust salt as needed. Evenly spread the beef and vegetable mixture in the skillet. Top with 6 oz sliced or shredded provolone cheese, then sprinkle with 1 cup shredded mozzarella cheese. This cheesy layer is key for your Protein-Packed Low Carb Philly Cheesesteak Casserole.
06 -
Transfer the skillet to the preheated 375°F oven. Bake for 15-20 minutes, or until the cheese is melted, bubbly, and lightly golden brown. Let the Protein-Packed Low Carb Philly Cheesesteak Casserole rest for 5 minutes before serving.
# Notes:
01 -
For an extra kick, try adding a dash of hot sauce to the creamy base or a few pickled jalapeño slices on top before baking.
02 -
Serve this hearty casserole as is, or with a side of low-carb bread for dipping, or a simple green salad to complete the meal.
03 -
Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat gently in the microwave or oven.
