Step‑by‑Step Instructions for Philly Cheesesteak Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it heats up, grab a 9×13-inch baking dish and coat it with non-stick cooking spray to ensure easy serving and cleanup later. This simple step sets the stage for your delicious Low Carb Philly Cheesesteak Casserole.
Step 2: Sauté the Vegetables
In a large skillet, heat about 1 tablespoon of olive oil over medium heat. Once the oil is shimmering, add the diced onion and bell peppers, sautéing them for 5-6 minutes until they soften and become fragrant. Stir in the minced garlic and cook for an additional 30 seconds, watching for its aroma; this creates a flavorful base for the casserole.
Step 3: Brown the Beef
Next, add the ground beef to the skillet, breaking it up with a spatula. Season generously with salt and pepper, and cook for 7-8 minutes until the meat is browned and fully cooked. Stir in the Worcestershire sauce during the last minute to incorporate that deep, savory flavor characteristic of Philly Cheesesteak Casserole.
Step 4: Create the Creamy Mixture
Reduce the heat to low and include 8 ounces of softened cream cheese into the skillet. Stir continuously until the cream cheese melts completely and blends smoothly with the beef and veggies, creating a rich, creamy mixture. This is the heart of your casserole, adding that delicious creaminess we love.
Step 5: Assemble the Casserole
Transfer the savory beef and vegetable mixture into your prepared baking dish, spreading it evenly. Layer the provolone cheese over the top for that traditional cheesesteak flavor, followed by an even distribution of shredded mozzarella cheese. This cheesy topping promises a delightful melt as it bakes.
Step 6: Bake to Perfection
Place your assembled Philly Cheesesteak Casserole in the preheated oven and bake for 20-25 minutes. Keep an eye on it; you’re looking for the cheese to become bubbly and golden brown, creating a beautiful, appetizing crust across the top.
Step 7: Cool and Serve
Once baked, remove the casserole from the oven and let it cool for about 5 minutes. This resting time allows the casserole to set a bit, making it easier to slice and serve. Your family will love diving into this creamy, cheesy delight that’s reminiscent of a classic cheesesteak!
