🛒 Ingredients
🥩 Main Components
- 1½ lbs ground beef or thinly sliced steak
- 1 medium onion, chopped
- 1 green bell pepper, diced
- 1 red bell pepper, diced
- 8 oz mushrooms, sliced
- 2 garlic cloves, minced
🧂 Seasoning Blend
- 1 teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon smoked paprika (optional)
- 1 tablespoon Worcestershire sauce
🥣 Creamy Layer
- 8 oz cream cheese, softened
- ½ cup mayonnaise
- 2 large eggs
🧀 Cheese Topping
- 1 cup shredded provolone
- 1 cup shredded mozzarella
👩🍳 Method
1️⃣ Preheat & Prepare
Set your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with butter or oil and keep it ready.
2️⃣ Brown the Meat
Place a large skillet over medium-high heat. Add the beef or sliced steak and cook until nicely browned, breaking it apart as needed.
Drain off any extra grease to keep the casserole from becoming oily.
3️⃣ Cook the Vegetables
To the same pan, add onion, bell peppers, mushrooms, and garlic. Sauté for about 5–6 minutes until the vegetables soften and release their aroma.
Sprinkle in salt, pepper, smoked paprika, and Worcestershire sauce. Stir thoroughly so everything is evenly seasoned.
4️⃣ Layer the Base
Spread the cooked meat and vegetable mixture evenly into the prepared baking dish.
5️⃣ Prepare the Creamy Mixture
In a separate bowl, whisk together softened cream cheese, mayonnaise, and eggs until smooth and lump-free. Make sure the cream cheese is soft to achieve a silky texture.
6️⃣ Assemble
Pour the creamy mixture evenly over the meat layer.
Top generously with shredded provolone and mozzarella cheese.
7️⃣ Bake
Place the dish in the oven and bake for 25–30 minutes, until the cheese is melted, lightly golden, and bubbling around the edges.
8️⃣ Rest Before Serving
Remove from the oven and allow it to sit for about 5 minutes. This helps the casserole firm up for easier slicing and serving.

💡 Helpful Tips
