Ingredients
For the Savory Beef & Veggie Layer
1½ lbs (680g) ground beef (or shaved ribeye steak for a more authentic bite)
1 medium onion, diced
1 green bell pepper, diced
1 red bell pepper, diced
8 oz (225g) cremini mushrooms, sliced
2 cloves garlic, minced
1 teaspoon salt
½ teaspoon black pepper
½ teaspoon smoked paprika (optional, for a deeper flavor)
1 tablespoon Worcestershire sauce
For the Creamy Cheese Base
8 oz (225g) cream cheese, softened
½ cup (120g) mayonnaise
2 large eggs, room temperature
For the Cheesy Finish
1 cup (100g) shredded provolone cheese
1 cup (100g) shredded mozzarella cheese
Instructions
Step 1: Preheat Oven & Prepare the Pan
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with butter or nonstick spray.
Step 2: Brown the Beef
In a large skillet over medium-high heat, cook the ground beef or shaved steak for 5–7 minutes until fully browned. Drain excess fat if desired. For extra depth of flavor, sear shaved steak before chopping—it enhances that classic cheesesteak taste.
Step 3: Sauté the Vegetables
Using the same skillet, add onion, both bell peppers, mushrooms, and garlic. Cook for 5–6 minutes, stirring often, until tender and lightly caramelized. Season with salt, pepper, smoked paprika, and Worcestershire sauce. Stir well to combine and remove from heat.
Step 4: Layer the Casserole
Spread the beef and veggie mixture evenly across the bottom of your prepared baking dish.
Step 5: Make the Creamy Base
In a separate bowl, beat together softened cream cheese, mayonnaise, and eggs until smooth and creamy. Pour this mixture over the beef and veggies, spreading gently with a spatula to cover evenly. Do not mix—each layer should remain distinct.
Step 6: Add the Cheesy Topping
Sprinkle shredded provolone and mozzarella evenly on top of the casserole.
Step 7: Bake to Perfection
Bake uncovered for 25–30 minutes until the top is golden brown, the edges are bubbling, and the center is set.
Step 8: Rest and Serve
Allow the casserole to rest for 5–10 minutes before slicing. This helps it hold its shape and makes serving easier. Enjoy warm as a main dish or spooned into hoagie rolls for a sandwich-style twist.
Tips for Success
- Use full-fat dairy for a creamier texture and better bake stability.
- Let the casserole rest before cutting—it will hold together beautifully.
- Shaved steak gives a more authentic cheesesteak bite, but ground beef is just as flavorful.
- The flavor deepens overnight, so leftovers taste even better the next day.
- For freezer prep, cool completely before wrapping and freezing.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the oven at 350°F (175°C) for 12–15 minutes for the best texture. You can also freeze the baked or unbaked casserole for up to 3 months—thaw overnight before reheating.
Ingredient Substitutions
- Ground beef → chicken, turkey, or plant-based meat substitutes (adjust cook time accordingly).
- Mayonnaise → Greek yogurt or sour cream for a tangier, lighter version.
- Provolone → Gouda, Pepper Jack, or Swiss for a different melt and flavor.
- Bell peppers → zucchini, spinach, or eggplant for a seasonal variation.
- Eggs → flax eggs (2 tbsp ground flax + 6 tbsp water) for a vegan-friendly texture.
Serving Suggestions
Serve family-style right from the baking dish for cozy gatherings. Pair it with a crisp green salad, garlic bread, or roasted vegetables. It’s perfect for game nights, meal prep, or holiday buffets. Double the recipe to feed a crowd or freeze half for future comfort-food cravings.
