Philly cheesesteaks are the ultimate comfort food, but what if you could enjoy all that cheesy, beefy goodness in an easy-to-make, family-friendly dish? That’s exactly why this Philly Cheesesteak Casserole is a must-try! It delivers everything you love about the classic sandwich—savory beef, sautéed peppers and onions, and plenty of melty cheese—but in a creamy, baked casserole that’s perfect for busy weeknights or game day gatherings. Even better, it’s low-carb, loaded with flavor, and ready in under an hour!
Did you know the Philly cheesesteak was born in the 1930s when a hot dog vendor in Philadelphia, Pat Olivieri, threw some sliced beef on the grill? A passing cab driver got a whiff, asked for a sandwich, and the rest is history! While the original version didn’t include cheese, today, provolone or Cheez Whiz are the go-to toppings.
Whether you’re meal-prepping, feeding a crowd, or just craving something hearty, this Philly Cheesesteak Casserole is the perfect answer. It’s easy, delicious, and sure to become a new favorite at your table!
Recipe Yield: 6 servings
INGREDIENTS
1 lb ground beef or 1 lb thinly sliced ribeye or sirloin steak (choose one)
1 tbsp beef broth
6 oz cream cheese, softened
1/2 cup heavy cream
1 green bell pepper, diced
1 small onion, diced
3 large eggs
1 tbsp olive oil
8 oz mushrooms, sliced
1 tsp garlic powder
1 tsp Worcestershire sauce
1/2 tsp salt
1/2 tsp black pepper
1 cup shredded provolone cheese
1/2 cup shredded mozzarella cheese
INSTRUCTIONS
1. Preheat oven: Set to 375°F (190°C) and lightly grease a 9×9-inch baking dish.
2. Cook the beef: In a large skillet over medium-high heat, fully cook the ground beef, breaking it up as it cooks, or sear the thinly sliced steak just until browned (it will finish cooking in the oven). Drain any excess grease and set aside.
3. Sauté the veggies: In the same skillet, heat olive oil and add bell pepper, onion, and mushrooms. Cook until softened, about 5 minutes. Stir in garlic powder, Worcestershire sauce, beef broth, salt, and black pepper.
4. Combine the base: Return the cooked beef to the skillet and mix in the cream cheese until melted and fully incorporated. Remove from heat.
5. Whisk the eggs: In a bowl, whisk together heavy cream and eggs until smooth.
6. Assemble the casserole: Spread the beef mixture evenly in the prepared baking dish. Pour the egg mixture over the top, then sprinkle with provolone and mozzarella cheese.
7. Bake to perfection: Place in the oven and bake for 25-30 minutes, or until the cheese is bubbly and the center is set.
8. Serve & enjoy: Let the casserole cool slightly before slicing. Serve hot and enjoy the ultimate Philly cheesesteak comfort meal!
Helpful Tips to Perfect This Recipe
- Use ribeye for extra flavor: Swap ground beef for thinly sliced ribeye for a more authentic Philly cheesesteak experience.
- Enhance the cheesiness: For extra gooeyness, add an extra sprinkle of cheese on top during the last 5 minutes of baking.
- Boost the seasoning: A dash of smoked paprika or a pinch of red pepper flakes can add depth and a little kick.
