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 is warming up, grab a 9×13 baking dish and prepare it with a light coating of non-stick spray. Ensuring your dish is ready will make transferring the Low Carb Philly Cheesesteak Casserole mixture much easier later on.
Step 2: Sauté the Vegetables
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the diced onion and bell peppers, sautéing for about 5–6 minutes, until the vegetables are soft and vibrant. Stir in the minced garlic and cook for an additional 30 seconds, allowing the fragrant aroma to fill your kitchen and enhancing the flavor of your casserole.
Step 3: Brown the Ground Beef
Next, add 2 pounds of ground beef to the skillet with the vegetables. Use a spatula to break the meat apart as it cooks, seasoning it generously with salt and pepper. Cook for 7–8 minutes, ensuring the beef is browned completely with no pink remaining. If there’s excess grease, drain it before continuing to keep your casserole from becoming soggy.
Step 4: Combine Ingredients
Stir in 2 tablespoons of Worcestershire sauce with the beef mixture, then add 8 ounces of softened cream cheese to the skillet. Mix everything together until the cream cheese has melted and created a rich, creamy consistency that binds the flavors. This creamy element is what makes the Low Carb Philly Cheesesteak Casserole comforting and delicious.
Step 5: Transfer the Mixture
Carefully spread the beef and veggie mixture evenly into the prepared baking dish. Layer 8 ounces of sliced provolone cheese over the beef, allowing it to melt deliciously during baking. Finally, sprinkle 1.5 cups of shredded mozzarella cheese generously on top to create a bubbly, cheesy crown for your casserole.
Step 6: Bake the Casserole
Place the baking dish in the preheated oven, baking it for 22–25 minutes. You’ll know it’s ready when the cheese is melted, bubbly, and lightly golden on top. This is the moment when your Low Carb Philly Cheesesteak Casserole starts to look irresistible, filling your home with an appetizing aroma.
Step 7: Rest and Serve
Once out of the oven, let the casserole rest for about 5 minutes before serving. This resting time allows the flavors to meld and ensures that each scoop holds together beautifully. Slice into your casserole and enjoy the rich, savory layers that bring a healthy twist to a classic dish!
