Step‑by‑Step Instructions for Low Carb Philly Cheesesteak Casserole
Step 1: Preheat and Prepare Baking Dish
Start by preheating your oven to 350°F (175°C). While the oven heats up, grab a 9×13-inch baking dish and lightly spray it with non-stick spray. This ensures that your Low Carb Philly Cheesesteak Casserole won’t stick when it’s time to scoop out those delicious portions!
Step 2: Sauté Vegetables
Heat a large skillet over medium heat and add a splash of olive oil. Once hot, toss in the diced onions and bell peppers, sautéing for about 5-6 minutes until they start to soften and become fragrant. Just before they’re done, mix in minced garlic and continue cooking for another 30 seconds to elevate those flavors.
Step 3: Brown the Ground Beef
Next, add the ground beef into the skillet. Season it with salt and pepper, then cook while breaking it apart with a spatula until the beef is evenly browned and no longer pink, around 7-8 minutes. This step builds a hearty base for your Low Carb Philly Cheesesteak Casserole!
Step 4: Incorporate Sauce
Once the beef is browned, stir in the Worcestershire sauce, ensuring that every bit of meat is well-coated in that rich, savory flavor. This small addition will enhance the overall taste of your casserole, making it truly special.
Step 5: Mix in Cream Cheese
Reduce the heat to low and add in the softened cream cheese. Stir vigorously until it melts and becomes creamy, creating a luscious mixture that perfectly melds with the beef and veggies. This step brings a smooth richness that’s essential for a delicious casserole.
Step 6: Assemble the Casserole
Transfer the beef mixture into your prepared baking dish, spreading it out evenly. Layer the top with slices of provolone cheese for that classic cheesesteak essence, and then sprinkle a generous amount of shredded mozzarella over it. The cheeses will create an irresistible gooey topping!
Step 7: Bake to Perfection
Place your assembled Low Carb Philly Cheesesteak Casserole in the preheated oven. Bake for 20-25 minutes, or until the cheese is bubbling and has turned a lovely golden color. Keep an eye on it to prevent over-browning, but don’t worry—this dish is all about that satisfying cheese melt!
Step 8: Rest Before Serving
Once your casserole is perfectly baked, remove it from the oven and let it rest for about 5 minutes. This will allow the layers to set slightly, making it easier to serve. Scoop out generous portions and enjoy the comforting flavors of your homemade creation!
