Ingredients

6
  • 1 pound flank steak, thinly sliced
  • 1 bell pepper, sliced
  • 1 onion, sliced
  • 2 cups mushrooms, sliced
  • 4 cloves garlic, minced
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 tablespoon olive oil
  • 1 cup shredded provolone cheese
  • 1 cup heavy cream
  • 1 large egg
  • 1 tablespoon Worcestershire sauce

Instructions

1

Preheat your oven to 350°F (175°C).

2

In a large skillet, heat olive oil over medium heat. Add the sliced onion and bell pepper and sauté for about 5 minutes until soft.

3

Add the mushrooms and garlic, cook until mushrooms release their juices, about 5 more minutes, then push the mixture to the side.

4

Add the flank steak to the skillet and season with salt, pepper, and Worcestershire sauce. Cook until just browned.

5

In a mixing bowl, whisk together heavy cream and egg. Add the meat and vegetable mixture and stir to combine.

6

Pour the mixture into a greased casserole dish. Top with shredded provolone cheese.

7

Bake in preheated oven for 25-30 minutes until the cheese is bubbly and slightly golden.

8

Let cool for a few minutes before serving.

Troubleshooting

If the casserole is too watery, let it bake a little longer.
If the cheese isn't melting, increase the oven temperature slightly.

Recipe Variations

Add jalapeños for a spicy kick.
Incorporate spinach or kale for a nutritional boost.

Healthy Alternatives

Use turkey or chicken instead of beef for a lighter option.
