Ingredients

Scale

Steak

  • 1 1/2 pounds boneless steak such as ribeye, filet, or sirloin
  • Neutral oil (as needed)
  • Kosher salt (to taste)
  • Freshly cracked black pepper (to taste)

Cowboy Butter

  • 1 stick unsalted butter (at room temperature)
  • 4 garlic cloves (minced)
  • 1/2 lemon (zested and juiced)
  • 1 tablespoon Dijon mustard
  • 1 teaspoon paprika
  • 1/2 teaspoon cayenne pepper
  • 1/2 teaspoon dried thyme
  • 1 teaspoon red pepper flakes
  • 1 tablespoon chives (minced)
  • 2 tablespoons fresh parsley (minced)
  • Kosher salt and pepper (to taste)

Caramelized Onions

  • 3 sweet onions (thinly sliced)
  • Butter (a few tablespoons for cooking onions)

Sliders

  • 9 slider buns
  • 3/4 pound sliced Havarti cheese

Instructions

  1. Prepare Steaks: Trim excess fat and silver skin from the steaks if necessary. Rub them all over with neutral oil and season generously on all sides with kosher salt and freshly cracked black pepper. For thicker steaks, increase seasoning.
  2. Season Steaks: Wrap the seasoned steaks tightly in plastic wrap and refrigerate for several hours to allow seasoning to penetrate deeply.
  3. Make Cowboy Butter: In a saucepan over low heat, gently melt the butter while whisking continuously. Add lemon juice and zest, minced garlic, Dijon mustard, paprika, cayenne, dried thyme, and red pepper flakes. Remove from heat and stir in minced chives and fresh parsley. Season with kosher salt and pepper to taste.
  4. Set Aside Butter Portions: Spoon a few tablespoons of the prepared cowboy butter into a small bowl for use during grilling, and keep the rest for brushing on slider buns later.
  5. Preheat Grill: Heat your grill to medium-high and establish an indirect heat zone. Remove steaks from the refrigerator and let them come to room temperature for about 30 minutes.
  6. Grill Steaks: Cook steaks directly over the heat for 2-3 minutes per side, avoiding charring by moving steaks to indirect heat if flames flare up. Brush both sides with cowboy butter as they cook. After 5-6 minutes total, transfer to the indirect heat area and continue cooking until desired doneness is reached.
  7. Rest Steaks: Remove steaks from the grill and tent loosely with foil. Let them rest for 10 minutes to allow juices to redistribute before slicing.
  8. Caramelize Onions: Place a cast iron skillet on the grill over direct heat and melt a few tablespoons of butter in it. Add the thinly sliced onions and cook, stirring occasionally, until they are golden brown and caramelized, approximately 15 minutes.
  9. Prepare Slider Buns: Preheat the oven to broil and line a baking sheet with parchment paper. Separate slider buns and brush the insides generously with the remaining cowboy butter. Layer Havarti cheese onto both top and bottom buns, then add caramelized onions on the bottom buns.
  10. Assemble Sliders: Place several slices of the rested steak onto the onion-topped bottom buns. Arrange sliders on the baking sheet and broil for 1-2 minutes or until the cheese is melted and bubbly.
  11. Serve: Top the steak with the prepared cheese and onion buns, slice if desired, and enjoy your flavorful Cowboy Butter Steak Sliders!

Notes

  • For best flavor, use ribeye or sirloin steaks with good marbling.
  • Adjust cayenne and red pepper flakes in the cowboy butter according to your preferred spice level.
  • Allowing the steak to rest after grilling ensures juicy, tender slices.
  • Cowboy butter can be made ahead and stored refrigerated for up to 3 days.
  • If you don’t have a grill, steaks can be cooked in a cast iron skillet over medium-high heat.
  • Use fresh herbs for the most vibrant flavor in the butter.
  • Slider buns can be substituted with mini brioche buns for a richer taste.
