About This Recipe
Philly cheesesteak is a legendary sandwich, famous for its juicy steak, sautéed onions, peppers, and melted cheese packed into a hoagie roll. But if you’re living a keto lifestyle, the bread is off the menu. Enter the Keto Philly Cheesesteak Skillet—a one-pan wonder that delivers all the flavor and comfort of the original, minus the carbs.
This skillet dish starts with thinly sliced ribeye (or flank steak), quickly seared until tender and juicy. Sautéed bell peppers and onions add sweetness and texture, while provolone or mozzarella cheese melts into the mix, binding everything together with gooey, cheesy goodness. The result is hearty, satisfying, and bursting with flavor—just like the sandwich you know and love.
One of the best parts about this recipe is how quick and easy it is to prepare. In less than 30 minutes, you can have dinner on the table with minimal cleanup. Since everything cooks in one skillet, it’s ideal for busy weeknights, but it’s also impressive enough to serve guests. Pair it with a simple side salad, roasted veggies, or keto-friendly bread if you want that handheld experience.
This dish is also highly versatile. Swap the beef for chicken or ground beef if you prefer, or use a mix of peppers for extra color. For a spicy kick, add sliced jalapeños or crushed red pepper flakes. You can even portion it out into small ramekins, top with cheese, and bake for a mini “cheesesteak casserole” twist.
Nutritionally, this skillet is keto gold. High in protein, rich in healthy fats, and naturally low in carbs, it keeps you full and satisfied without knocking you out of ketosis. It’s proof that comfort food doesn’t have to mean carb overload.
Whether you’re a Philly cheesesteak purist or just looking for a quick keto dinner that feels indulgent, this skillet has you covered. It’s a crowd-pleaser that delivers bold flavors with minimal effort, making it one of those recipes you’ll turn to again and again.
