Step‑by‑Step Instructions for Low Carb Philly Cheesesteak Casserole

Step 1: Preheat Oven and Prepare Baking Dish
Begin by preheating your oven to 350°F (175°C). While it heats up, take a 9×13 baking dish and spray it with non-stick cooking spray to ensure your casserole doesn’t stick. This will provide a lovely golden crust on your Low Carb Philly Cheesesteak Casserole after baking.

Step 2: Sauté Vegetables
Heat 1 tablespoon of olive oil in a large skillet over medium heat. Once the oil shimmers, add the diced onion and bell peppers. Sauté them for about 5-6 minutes until they are softened and fragrant, stirring occasionally. Add 2 cloves of minced garlic and continue cooking for an additional 30 seconds, breathing in the enticing aroma as they blend together.

Step 3: Cook Ground Beef
Add 2 pounds of ground beef to the skillet with the sautéed vegetables. Use a spatula to break the meat apart as it cooks. Season with salt and pepper to taste, and stir it well. Cook for about 7-8 minutes until the beef is browned and no pink remains. If there’s excess fat, drain it to maintain a firmer texture in your casserole.

Step 4: Incorporate Cream Cheese and Worcestershire Sauce
Stir in 2 tablespoons of Worcestershire sauce, mixing to combine it thoroughly with the beef mixture. Reduce the heat to low and add 8 ounces of softened cream cheese. Stir until the cream cheese has melted and is creamy, wrapping around the seasoned beef and veggies for that rich flavor in your Low Carb Philly Cheesesteak Casserole.

Step 5: Transfer to Baking Dish
Carefully spread the beef mixture evenly in the prepared baking dish, ensuring every corner is filled with that mouthwatering blend. Tear 8 ounces of provolone cheese into pieces and layer them over the top of the beef mixture. Finally, sprinkle 1.5 cups of shredded mozzarella cheese over everything, creating a luscious, cheesy topping.

Step 6: Bake Until Bubbly
Place the casserole in the preheated oven and bake for 22-25 minutes. Keep an eye on it, as you’ll know it’s ready when the cheese is melted, bubbly, and begins to turn a lovely golden brown. This final layer of gooey cheese will make your Low Carb Philly Cheesesteak Casserole irresistibly tempting.

Step 7: Rest Before Serving
Once baked, remove the casserole from the oven and allow it to rest for about 5 minutes. This resting period will help the flavors meld together, making each bite even more delightful. Serve warm and enjoy the comforting, cheesy goodness that this dish brings to your dinner table.

If you find your Low Carb Philly Cheesesteak Casserole is a bit greasy, don’t worry! After cooking your ground beef and before adding it to the casserole, make sure to drain any excess fat from the skillet.

Is this casserole suitable for gluten-free diets?
