Ingredients
Main Ingredients
- 1 tablespoon olive oil
- 1.5 lbs thinly sliced ribeye steak or sirloin cut into bite-sized pieces (shaved steak works great too!)
- 1 large onion thinly sliced
- 2 bell peppers (any color) thinly sliced
- 1 teaspoon garlic powder
- ½ teaspoon salt
- ¼ teaspoon black pepper
Cheese Sauce
- 8 ounces cream cheese softened
- ½ cup heavy cream
- ½ cup beef broth
- 1 teaspoon Worcestershire sauce
Topping
- ½ cup shredded provolone cheese divided
- ½ cup shredded mozzarella cheese divided
- sliced jalapeños Optional topping
- red pepper flakes Optional topping
- fresh parsley Optional topping
Instructions
Preparation
- Preheat your oven to 375°F (190°C), then heat olive oil in a large skillet over medium-high heat.
- Sear the thinly sliced steak in batches for 2-3 minutes per side until browned; remove and set aside.
- In the same skillet, cook the sliced onion and bell peppers for 8-10 minutes until softened, then stir in garlic powder, salt, and black pepper.
Assembly
- Whisk together softened cream cheese, heavy cream, beef broth, and Worcestershire sauce until smooth, then stir in half of the provolone and mozzarella cheeses.
- Return the seared steak to the skillet with the vegetables and mix, then pour the cheese sauce over and gently stir to coat.
- Transfer the mixture to a 9x13 inch baking dish and sprinkle with the remaining provolone and mozzarella cheese.
Baking
- Bake for 20-25 minutes until bubbly and golden, then broil for 1-2 minutes if desired for extra browning.
- Remove from oven, let rest for 5 minutes, and garnish with optional toppings like fresh parsley or red pepper flakes before serving.
Notes
For a spicier kick, add a pinch of red pepper flakes to the vegetables while cooking, or top with sliced jalapeños before serving. Ensure your cream cheese is at room temperature for a smoother sauce. If you don't have ribeye or sirloin, any thinly sliced beef suitable for stir-frying can work.
