Step‑by‑Step Instructions for Low Carb Philly Cheesesteak Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms up, grab a 9×13 baking dish and apply a generous coat of non-stick spray. This will ensure that your Low Carb Philly Cheesesteak Casserole doesn’t stick to the dish during baking, making for easier serving and cleanup.
Step 2: Sauté the Veggies
In a large skillet, pour in 1 tablespoon of olive oil and heat it over medium heat. Once the oil shimmers, add your diced onions and bell peppers. Sauté these for about 5-6 minutes, stirring occasionally, until they become tender and fragrant. Add in the minced garlic and cook for another 30 seconds, allowing its aroma to fill your kitchen.
Step 3: Brown the Beef
Next, incorporate the 2 lbs of ground beef into the skillet with the sautéed veggies. As the beef cooks, break it apart with a spatula or wooden spoon. Season with salt and pepper to taste, and let it brown for 7-8 minutes. Once fully cooked, drain any excess fat to keep your casserole from becoming greasy.
Step 4: Mix in Cream Cheese
After draining the fat, reduce the heat and pour in 2 tablespoons of Worcestershire sauce, stirring to coat the meat evenly. Then, add the softened 8 oz of cream cheese to the skillet. Gently mix until the cream cheese melts and blends into the beef mixture, creating a creamy texture that enhances the flavors of your Low Carb Philly Cheesesteak Casserole.
Step 5: Transfer and Layer
Carefully transfer the beef mixture into your prepped baking dish. Spread it out evenly, ensuring every corner gets that delicious filling. Next, layer the casserole with torn slices of provolone cheese, followed by a generous sprinkle of 1.5 cups of shredded mozzarella cheese on top. This cheesy layer will turn bubbly and golden as it bakes.
Step 6: Bake the Casserole
Slide the baking dish into the preheated oven and let it bake for 22-25 minutes. Keep an eye on it: you’ll know it’s ready when the cheese is melted and lightly golden brown on top. The enticing aroma will fill your kitchen, promising a delightful meal.
Step 7: Rest and Serve
Once the baking time is up, remove the casserole from the oven and let it rest for about 5 minutes. This resting period allows the flavors to settle and makes it easier to serve. Cut into squares, dish it out, and savor every delicious bite of your Low Carb Philly Cheesesteak Casserole!
