Diner Breakfast Steak with Onions

Ingredients

• 2 top sirloin steaks, about 8 oz each and 1/2 inch thick
• 1 1/2 tsp kosher salt
• 1 tsp coarsely ground black pepper
• 1/2 tsp garlic powder
• 1 tbsp vegetable oil
• 2 tbsp unsalted butter
• 1 large yellow onion, sliced 1/4 inch thick
• 1 tbsp Worcestershire sauce
• 2 tbsp water

Before you cook

• Take the steaks out of the refrigerator 30 minutes ahead so they lose their chill.
• Pat both sides of each steak completely dry with paper towels.
• Season both sides with the salt, pepper and garlic powder, pressing the seasoning in.
• Slice the onion into quarter-inch half-moons.

Steps

1. Heat a 12-inch cast-iron skillet over high heat for 4 minutes, until a drop of water skitters and vanishes instantly.
2. Add the oil and swirl it to coat the pan.
3. Lay the steaks in the pan, laying them away from you.
4. Sear 3 minutes without moving them, until a dark brown crust has formed.
5. Flip the steaks with tongs and sear 2 to 3 minutes on the second side for medium-rare, or until an instant-read thermometer reads 130°F.
6. Move the steaks to a plate and tent them loosely with foil to rest.
7. Reduce the heat to medium and add the butter and sliced onion to the same pan.
8. Cook the onions 8 minutes, stirring and scraping up the browned bits, until they are limp and browned at the edges.
9. Add the Worcestershire sauce and water and let them bubble for 1 minute, until the pan is nearly dry again.
10. Pour any juices from the resting plate into the onions and stir.
11. Slice the steaks against the grain, pile the onions over them and serve.
