How to Make Low Carb Philly Cheesesteak Casserole

In the same skillet, add the sliced onion and bell pepper. Cook for 4-5 minutes, or until softened. Season with garlic powder, onion powder, salt, and pepper.

Pour the heavy cream into the skillet with the vegetables and bring to a simmer. Stir in the provolone and cheddar cheese until melted and smooth.
Step 4: Combine Steak and Sauce
Return the cooked steak to the skillet and stir everything together to combine.
Step 5: Assemble the Casserole
Preheat your oven to 375°F (190°C). Grease a baking dish with cooking spray or butter. Transfer the steak and vegetable mixture into the dish, spreading it evenly.
