Ingredients

Why this recipe works

The method of cooking the ground beef and peppers together in a single skillet ensures that the juices from the vegetables are absorbed by the meat, intensifying the overall flavor profile of the dish. This technique creates a cohesive filling that remains moist even after being baked in the oven, providing a superior texture compared to methods where ingredients are added separately.

Using a high-heat bake finish for the mozzarella topping is crucial for achieving the iconic golden-brown crust and gooey pull that defines this casserole. By allowing the cheese to bubble rapidly under concentrated heat, the fat and proteins in the cheese emulsify into a rich, stretchy layer that contrasts perfectly with the savory, tender beef and pepper mixture underneath.

Notes and substitutions

For the best results, use a high-quality shredded mozzarella cheese rather than pre-packaged shredded cheese if possible, as it melts more evenly and produces a better stretch.

If using pre-packaged, ensure it does not contain added anti-caking agents that can interfere with the melting process. You can also experiment with a blend of cheeses to adjust the saltiness and creaminess to your personal preference.

A large, heavy-bottomed skillet is recommended for browning the meat, as it provides the thermal mass needed to sear the beef effectively without steaming it.

If you do not have a 9x13 inch baking dish, you can use two smaller square dishes, though this will change the total bake time slightly. Always ensure the baking dish is oven-safe and large enough to hold the mixture without overflowing.

• ground beef: ground turkey or ground chicken for a different protein base while maintaining the same cooking method and texture.
• mozzarella cheese: provolone cheese or a blend of Monterey Jack for a sharper, more traditional cheesesteak flavor profile.
