This one pan meal of steak and potatoes is sure to be crowd favorite. The steak is seared to perfection and those roasted potatoes you'll want to pop in your mouth like candy.
Preheat your oven to 375°F (180°C). Lightly oil a baking sheet or coat with nonstick spray.
Place halved potatoes in a single layer onto one side of the prepared baking sheet. Add olive oil, garlic, and Italian seasoning; season with salt and pepper, to taste. Gently toss to combine. Transfer into the oven and bake for 20-25 minutes, until golden brown and crisp, tossing occasionally.
In the meantime, prepare the spice mix by combining salt, black pepper, garlic powder, Italian seasoning, paprika, Cayenne and chili pepper flakes in a small bowl or shallow plate. Season steaks by rubbing the spice mix on both sides.
When potatoes are ready, remove from oven and switch to broil mode. Place seasoned steaks onto the opposite side of the prepared baking sheet
Place back into the oven and broil until the steak is browned and charred at the edges, about 4-5 minutes per side for medium-rare, or until desired doneness. For thinner cuts of steak, simply broil on one side only.
When done, sprinkle potatoes with parmesan and fresh chopped parsley and serve directly from the sheet pan, along with the caramelized onion. Enjoy!
Notes
You can pre-cook potatoes by boiling them for 3-4 minutes before baking.
