Introduction

Looking for a comforting, crowd-pleasing dish that skips the extra carbs but delivers all the flavor? This Cheesy Low Carb Philly Cheesesteak Casserole Recipe transforms the classic sandwich into a bubbling bake—perfect for weeknight dinners or potluck gatherings. With succulent beef, melty cheese, and colorful veggies, every bite is savory, satisfying, and keto-friendly.

What Makes This Low Carb Casserole a Must-Try?

This recipe captures everything you love about a Philly cheesesteak—thin-sliced beef, sautéed onions and peppers, gooey cheese—without the bread. By swapping out the traditional hoagie roll for a casserole base, you get all the indulgence in a lighter, low-carb form. It’s incredibly simple to prep and makes for fantastic leftovers.

Ingredient Prep Made Easy

Efficiency is key when prepping veggies for this casserole. Quickly dice onions, bell peppers, and mushrooms with the convenience of a Mueller Pro-Series 10-in-1, 8 Blade Vegetable Chopper—you’ll have even-sized pieces for even cooking. Using a quality Lodge 10.25 Inch Cast Iron Pre-Seasoned Skillet ensures your beef browns perfectly and your onions caramelize for maximum flavor.

Building Layers of Flavor

Start by browning thinly sliced beef in your skillet and set it aside. In the same pan, sauté vegetables until tender, then combine with the beef, cream cheese, and seasonings. To break up and mix the meat, a Farberware Professional Heat Resistant Nylon Meat and Potato Masher works wonders, especially for evenly distributing cheese and spices.

Assembling and Baking the Casserole

Spread your beef and veggie mixture into a casserole dish, then top with generous layers of provolone or mozzarella cheese. Lining your dish with a sheet of Reynolds Kitchens Brown Parchment Paper Roll ensures easy serving and cleanup. Bake until golden, bubbly, and irresistible.

Serving and Storing Tips

For simple portioning and portable lunches, pack leftovers into a Bentgo Salad Container – 54 oz Bowl. Pair the casserole with a crisp green salad or roasted vegetables for a complete meal.

Instructions

1. Preheat oven to 375°F. For no-stick ease, line a medium baking dish with a sheet from the Reynolds Kitchens Brown Parchment Paper Roll.
