How to Make Keto Philly Cheesesteak Casserole
Cook the Beef: In a large skillet, cook the ground beef or shaved steak over medium heat until browned, about 5-7 minutes. Drain any excess fat to keep it light and delicious.
Saut the Veggies: Add the sliced green bell pepper, onion, and mushrooms to the skillet. Stir and saut for another 5 7 minutes until they are tender and vibrant.
Mix the Creamy Base: Stir in the softened cream cheese, sour cream, garlic powder, salt, and pepper. Keep mixing until everything is smooth and creamy, making sure all the flavors meld beautifully.
Preheat the Oven: While you re mixing, preheat your oven to 375 °F (190 °C). This is the perfect temperature to create a golden, bubbly casserole.
Transfer and Top: Transfer the creamy beef mixture into a greased baking dish. Evenly sprinkle the shredded provolone or mozzarella cheese on top, covering every bit of that luscious filling.
Bake: Place the dish in the preheated oven and bake for 15 20 minutes, or until the cheese is melted and bubbly. For an extra touch, broil for 2 3 minutes to achieve a lovely golden top.
Optional: Serve with a sprinkle of red pepper flakes for some heat or chopped parsley for a fresh finish.
