"Cheesesteak" Bake with Peppers, Mushrooms, Onions & Melted Mozzarella

Directions

1. 1. Preheat the oven to 425°F and line a sheet pan if you like for easy cleanup.
2. 2. Clean and dry all fresh produce, then slice the bell peppers, mince the garlic, and cut the onion into thin half-moons.
3. 3. Toss the peppers, mushrooms, garlic, and onion with a little salt and pepper, spread in an even layer on the sheet pan, and scatter small chunks of butter over the top.
4. 4. Roast the vegetables in the oven, stirring halfway, until they’re tender and lightly browned, about 15 minutes.
5. 5. While the veggies roast, pat the steak dry and season it on both sides with salt, pepper, and any dried thyme or parsley you like.
6. 6. Heat a skillet over medium-high and melt a bit of butter to coat the bottom. Sear the steak until it reaches your preferred doneness, about 2–5 minutes per side, then rest briefly on a plate.
7. 7. Grate the mozzarella and prepare the parsley by discarding stems and finely chopping the leaves.
8. 8. When the vegetables are done, remove the sheet from the oven, turn on the broiler, and move a rack close to the heat.
9. 9. Slice the steak thinly against the grain, lay the slices over the roasted vegetables, sprinkle with mozzarella, and return to the oven to broil until the cheese melts, about 1 minute.
10. 10. Transfer to plates, sprinkle with parsley, and serve.
