Ingredients Method Notes

Ingredients
  

  • 1 pound tiny new red and/or yellow potatoes halved
  • 12 ounces green beans trimmed
  • 1 small red onion cut into 1-inch wedges
  • 2 tablespoons olive oil divided
  • ¾ teaspoon kosher salt divided
  • ½ teaspoon black pepper divided
  • 1 pound beef sirloin steak cut into 1½-inch pieces
  • 1 tablespoon Worcestershire sauce
  • 2 tablespoons butter
  • 1 clove garlic grated
  • 2 teaspoons chopped fresh rosemary or parsley

Method
 

  1. Place an oven rack about 6 inches from the heat source. Preheat the oven to 450°F (230°C). Lightly coat a 10×15-inch baking sheet with cooking spray.
  2. In a medium bowl, toss potatoes, green beans, and red onion with 1 tablespoon olive oil, ¼ teaspoon kosher salt, and ¼ teaspoon black pepper.
  3. Spread the vegetables evenly across the prepared baking sheet.
  4. Roast the vegetables in the oven for 15 minutes, stirring halfway through, until the potatoes begin to soften and the vegetables develop roasted edges.
  5. While the vegetables cook, toss steak pieces with Worcestershire sauce, the remaining 1 tablespoon olive oil, ½ teaspoon kosher salt, and ¼ teaspoon black pepper.
  6. Preheat the broiler. Push the roasted vegetables toward the edges of the baking sheet and arrange the steak pieces in a single layer in the center.
  7. Broil the steak, turning halfway through, until cooked to your preferred doneness. For medium steak, the internal temperature should reach about 140–145°F (60–63°C), which usually takes 6–8 minutes.
  8. Meanwhile, melt butter in a small saucepan over medium heat. Add grated garlic and cook for about 30 seconds until fragrant. Remove from heat and stir in rosemary or parsley.
  9. Drizzle the garlic butter over the steak and vegetables before serving.

Notes

  • This recipe uses one sheet pan to cook the steak, potatoes, green beans, and onion together for easy cleanup.
  • Roasting the vegetables first gives the potatoes enough time to become tender before the steak is added.
  • Steak doneness can be adjusted based on your preference.
  • Add the garlic butter after cooking to preserve the fresh garlic and herb flavor.
  • A meat thermometer is the most reliable way to check steak doneness.
