Why This Philly Cheesesteak Casserole Is Irresistible

This casserole stands apart for its incredible flavor depth and unbeatable cheesy topping—while remaining keto-friendly.

It’s quick to assemble and holds up wonderfully for leftovers, making meal prep a breeze.

How to Prepare the Ingredients Efficiently

A huge part of this recipe’s convenience is easy, efficient prep. Use a Mueller Pro-Series 10-in-1, 8 Blade Vegetable Chopper to quickly dice onions and bell peppers into even pieces, ensuring consistent flavor and a beautiful presentation. For slicing beef, a sturdy Bamboo Cutting Board gives you a safe, stable surface that won’t dull your knives.

If you’re doubling the batch or cooking for a crowd, a Homaxy 100% Cotton Waffle Weave Kitchen Dish Cloth on hand helps keep counters clean and speeds up cleanup.

Sautéing, Building Flavor, and Baking

Start by browning your ground beef and sautéing vegetables in a quality skillet, like the SENSARTE Nonstick Frying Pan Skillet, to develop maximum flavor and prevent sticking. The nylon head of a Farberware Professional Heat Resistant Nylon Meat and Potato Masher breaks up the beef effortlessly and ensures even cooking.

After layering your sautéed beef and veggies with cheese, bake the casserole using a sheet of Reynolds Kitchens Brown Parchment Paper Roll to avoid stuck-on mess and simplify lifting portions from the pan.

Serving and Storing Your Cheesy Philly Cheesesteak Casserole

Let the casserole rest briefly after baking for the flavors to meld and the cheese to set. Serve generous scoops in bowls or, for meal prep, pack portions into a Bentgo Salad Container for an on-the-go lunch that reheats beautifully. Top with a drizzle of hot sauce, fresh herbs, or even a handful of pickled jalapeños for variety.

This casserole keeps well refrigerated for up to four days—perfect for prepping ahead and enjoying all week long.
