Instructions
Step 1: Sizzle the Steak
Preheat your oven to 375°F (190°C). Heat olive oil in a large skillet over medium-high heat. Add the steak and cook until nicely browned. Set aside.
Step 2: Sauté the Veggies
In the same skillet, sauté the onions, peppers, mushrooms, and garlic until tender and slightly caramelized. Season with salt and pepper.
Step 3: Layer the Casserole
Grease a 9×13-inch baking dish. Spread half the veggies in the bottom, top with the steak, then sprinkle with half the shredded provolone. Repeat layers.
Step 4: Make the Topping
In a bowl, whisk together the flour, melted butter, beef broth, Worcestershire sauce, and salt.
Step 5: Bake to Perfection!
Pour the topping evenly over the casserole. Bake for 25-30 minutes, or until golden brown and bubbly.
Variations
Make it your own!
- Use sirloin or flank steak.
- Experiment with cheddar, mozzarella, or other cheeses.
- Add a kick with jalapeños or red pepper flakes.
- For a low-carb option, use almond flour and melted butter for the topping.
Tips for Success
- Slice the steak thinly for even cooking.
- Don’t overcook the veggies; they’ll continue cooking in the oven.
- Let it cool a bit before serving – the flavors will meld beautifully.
- Leftovers? Store in an airtight container in the fridge for up to 3 days.
