What Makes This Philly Cheesesteak Casserole Irresistible

This innovative recipe features tender strips of beef, an abundance of sautéed peppers and onions, and a luscious layer of melty cheese. The secret is maximizing the classic flavors with just a few strategic swaps for a low-carb twist. Your table will be filled with the delicious aroma of caramelized veggies and bubbling cheese, making even the pickiest eaters ask for a second serving.

Prepping the Veggies for Flavor and Texture

For that signature Philly flavor, perfectly diced peppers and onions are crucial. Want razor-sharp precision and time-saving convenience? Use the Mueller Pro-Series 10-in-1, 8 Blade Vegetable Chopper to chop your bell peppers and onions evenly and quickly, ensuring perfect texture every time. Uniformity helps everything cook evenly and meld together seamlessly in your casserole.

Building Your Cheesy Casserole Layers

Start by browning your beef in a dependable skillet. The SENSARTE Nonstick Frying Pan Skillet, 9.5 Inch is excellent for achieving a seared crust without sticking, making cleanup a breeze. After removing the beef, use the same pan to sauté your chopped veggies until soft and caramelized, layering on classic flavor.

Layer the veggies and beef in a casserole dish, then top everything with a generous mound of shredded provolone and mozzarella cheeses. Bake until golden and bubbly for maximum mouthwatering appeal.

Perfectly Melty Cheese: Oven-Baking Tips

To achieve that irresistible cheesy crust that stretches beautifully with every forkful, line your baking dish with Reynolds Kitchens Brown Parchment Paper Roll. This not only prevents sticking but also makes transferring leftovers effortless.

Keep an eye on your bake time—once the cheese turns golden brown and the edges are bubbling, your casserole is oven-ready for serving.
