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, lightly spray a 9×13-inch baking dish with non-stick cooking spray to prepare it for the casserole. This will ensure your Low Carb Philly Cheesesteak Casserole easily releases after baking, leading to a beautifully presented dish.
Step 2: Sauté the Vegetables
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Once the oil shimmers, add the diced large onion and bell peppers. Sauté these for 5-6 minutes until they soften and become fragrant, showcasing vibrant colors. At the last 30 seconds of cooking, stir in minced garlic for an aromatic kick.
Step 3: Brown the Ground Beef
Add the 1 pound of ground beef to the skillet, breaking it apart with a spatula. Season the meat generously with salt and pepper, then cook for about 7-8 minutes until browned and fully cooked. Ensure there’s no pink left to achieve that savory meaty flavor for your Low Carb Philly Cheesesteak Casserole.
Step 4: Mix in Flavorings
Once the beef is browned, stir in 2 tablespoons of Worcestershire sauce, mixing well to combine. Lower the heat to medium-low, and add in 8 ounces of cream cheese. Stir until the cream cheese melts and the mixture becomes creamy, creating a luscious base for the casserole, bursting with flavor.
Step 5: Assemble the Casserole
Transfer the beef mixture into your prepared baking dish, ensuring it’s evenly spread. Next, layer 4 ounces of provolone cheese over the top, followed by a generous sprinkle of 1 cup of shredded mozzarella cheese. This cheesy layer will create that delightful gooey texture everyone loves.
Step 6: Bake to Perfection
Place the assembled casserole in your preheated oven and bake for 20-25 minutes. Watch for the cheese to bubble and turn golden brown, indicating it’s perfectly baked and ready to be devoured. The aroma will fill your kitchen, making it hard to resist!
Step 7: Rest Before Serving
Once baked, remove the casserole from the oven and allow it to rest for 5 minutes. This short cooling period helps the layers set slightly, making it easier to serve. After resting, you can cut into your Low Carb Philly Cheesesteak Casserole and enjoy each delicious bite!
