Ingredients You’ll Need
Main Ingredients:
- 1½ pounds thinly sliced ribeye steak (or sirloin)
- 1 tablespoon olive oil
- 1 green bell pepper, sliced
- 1 red bell pepper, sliced
- 1 large onion, sliced
- 2 cloves garlic, minced
- 4 oz cream cheese, softened
- ½ cup sour cream
- 1 teaspoon Worcestershire sauce
- 1½ cups shredded mozzarella cheese
- 1 cup provolone cheese, shredded
- ½ teaspoon paprika
- Salt and black pepper to taste
Optional Topping:
- 1 cup crispy French-fried onions or crushed crackers for crunch
Step-by-Step Instructions
1. Sauté the Veggies & Steak
In a large skillet, heat olive oil over medium-high heat. Sauté onions and peppers until they begin to soften, about 5–6 minutes. Add garlic and cook for another minute. Remove veggies and set aside.
Add the sliced steak to the same skillet and cook until browned. Season with salt, pepper, and paprika.
2. Prepare the Creamy Base
In a large bowl, mix the softened cream cheese, sour cream, and Worcestershire sauce until smooth. Fold in half of the shredded mozzarella and provolone.
3. Combine and Layer
Preheat oven to 375°F (190°C). In a 9×13” baking dish, mix the steak, sautéed veggies, and cheese mixture. Top with remaining mozzarella and provolone.
4. Bake to Perfection
Bake uncovered for 20–25 minutes, or until cheese is melted and bubbly. For a crispy topping, sprinkle crushed crackers or fried onions during the last 5 minutes.
5. Serve Hot
Let it cool for 5–10 minutes before serving. Enjoy as is or pair with garlic bread or salad!
