Ingredients Equipment Method Notes

Ingredients
  

  • 1-1.5 pounds sirloin, flank steak, or ribeye
  • 1 tablespoon olive oil
  • Salt and pepper to taste
  • 1/2 cup unsalted butter 1 stick
  • 4-5 cloves fresh garlic, minced
  • 2 tablespoons fresh parsley, chopped
  • 2 tablespoons fresh thyme, chopped
  • 2 tablespoons fresh rosemary, chopped
  • 1/2 teaspoon red pepper flakes adjust to taste
  • 1 teaspoon smoked paprika
  • 1 tablespoon lemon juice
  • 1 teaspoon Dijon mustard
  • 1 teaspoon Worcestershire sauce
  • 12 slider buns Hawaiian rolls recommended
  • Optional: Provolone cheese slices
  • Optional: Caramelized onions
  • Optional: Fresh parsley for garnish

Equipment

  • Cast iron skillet or heavy-bottomed skillet
  • Small saucepan
  • Cutting board
  • Knife
  • Measuring spoons
  • Measuring cups
  • Meat thermometer
  • Paper towels
  • Foil
  • Baking sheet (optional)

Method
 

  1. Take the steak out of the refrigerator about 30 minutes before cooking to bring it to room temperature.
  2. Pat the steak dry with paper towels and season generously with salt and pepper on both sides.
  3. Heat a cast-iron skillet over high heat and add olive oil.
  4. Once the oil is shimmering and almost smoking, carefully place the steak in the skillet.
  5. Sear for 3-4 minutes per side for medium-rare, or longer to reach your desired internal temperature. Use a meat thermometer to ensure accuracy.
  6. Remove the steak from the skillet and place it on a cutting board. Tent loosely with foil and let it rest for at least 10 minutes.
  7. While the steak is resting, melt the butter in a small saucepan over medium heat.
  8. Add the minced garlic and cook for about 1 minute, until fragrant, being careful not to burn it.
  9. Remove the saucepan from the heat and stir in the chopped parsley, thyme, rosemary, red pepper flakes, smoked paprika, lemon juice, Dijon mustard, and Worcestershire sauce.
  10. Season the cowboy butter with salt and pepper to taste and stir well to combine.
  11. Slice the rested steak thinly against the grain.
  12. Slice the slider buns in half and spread a generous amount of cowboy butter on both the top and bottom buns.
  13. Place a few slices of steak on the bottom bun. Top with provolone cheese (if using) and the top bun.
  14. Optional: For extra melty cheese, place the assembled sliders on a baking sheet and broil them for a minute or two, until the cheese is melted and bubbly. Watch closely to prevent burning.
  15. Serve immediately and garnish with fresh parsley, if desired.

Notes

The cowboy butter can be made up to 3 days in advance and stored in the refrigerator. Reheat gently before using. The steak can also be cooked and sliced ahead of time. Assemble sliders right before serving to prevent soggy buns. Leftover sliders can be stored in the refrigerator for up to 2 days. Variations: Try different cheeses like cheddar or Monterey Jack, add cayenne pepper for extra heat, or include caramelized onions or sauteed mushrooms for added flavor. Serve with fries, coleslaw, potato salad, corn on the cob, or a simple green salad.
