🍳 Instructions
1. Preheat the Oven
Set your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish to prevent sticking.
2. Cook the Meat
In a large skillet over medium-high heat, brown your ground beef (or shaved steak) until fully cooked. Drain off any excess grease to keep the dish from becoming oily.
3. Sauté the Vegetables
Add the diced onion, green and red peppers, mushrooms, and garlic to the skillet. Sauté for 5–6 minutes, or until softened and fragrant. Season with salt, pepper, smoked paprika, and Worcestershire sauce.
4. Layer the Casserole
Spread the cooked beef and vegetable mixture evenly across the bottom of your prepared baking dish.
5. Mix the Creamy Base
In a medium bowl, whisk together the cream cheese, mayonnaise, and eggs until smooth and creamy. This mixture binds everything together and gives the dish that irresistible richness.
6. Assemble and Top
Pour the cream mixture over the beef and vegetables, spreading evenly. Top with a generous layer of shredded provolone and mozzarella cheese.
7. Bake to Perfection
Bake uncovered for 25–30 minutes, or until the top turns golden brown and starts to bubble around the edges.
8. Let It Rest
Allow the casserole to cool for 5 minutes before serving. This helps it set and makes slicing easier.
🍽 Serving Suggestions
This Philly Cheesesteak Casserole is delicious on its own, but you can elevate it with:
- A side salad for freshness
- Toasted hoagie rolls if you want that sandwich feel
- Garlic bread to soak up every last bit of cheesy goodness
It also reheats beautifully, making it perfect for leftovers or meal prep.
❤️ Why This Recipe Works
This casserole nails the balance of flavors — the juicy beef, the sweetness of the peppers, the tangy Worcestershire, and that smooth, melty cheese finish. It’s hearty without being heavy, indulgent without being greasy, and familiar yet new.
Whether you’re feeding a crowd or just looking to treat yourself after a long day, this dish delivers pure comfort in every bite.
Pro Tip: For a low-carb version, skip the hoagie rolls and use lean ground beef or turkey. You’ll still get all the flavor with fewer calories.
