Ingredients

Scale

Steak and Buns

  • 1 1/2 pounds boneless steak such as ribeye (filet, sirloin)
  • Neutral oil (as needed)
  • Kosher salt (to taste)
  • Freshly cracked black pepper (to taste)
  • 9 slider buns
  • 3/4 pound sliced Havarti cheese

Caramelized Onions

  • 3 sweet onions (thinly sliced)
  • Butter (for caramelizing onions)

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 black pepper (to taste)

Instructions

  1. Prepare Steaks: Trim any excess fat and silver skin from the steaks. Rub the steaks with neutral oil and season generously with kosher salt and freshly cracked black pepper on all sides. For thicker cuts, apply seasoning more heavily.
  2. Season and Rest: Wrap the seasoned steaks tightly in plastic wrap and refrigerate for a few hours to allow the seasoning to penetrate the meat deeply.
  3. Make Cowboy Butter: In a saucepan over low heat, melt the stick of unsalted butter, whisking continually. Add the lemon zest and juice, minced garlic, Dijon mustard, paprika, cayenne, dried thyme, and red pepper flakes. Remove from heat and stir in the minced chives and fresh parsley. Season with kosher salt and black pepper to taste. Spoon out a few tablespoons into a small bowl for basting steak while grilling; reserve the remaining butter for brushing on slider buns.
  4. Cook Steaks: Preheat your grill to medium-high heat, setting up an indirect heat zone. Remove the steaks from the refrigerator and let them rest at room temperature for 30 minutes. Grill the steaks over direct heat for 2-3 minutes per side, avoiding charring. If flames flare up, move steaks to indirect heat until flames subside. Brush both sides with cowboy butter throughout cooking. After 5-6 minutes of total direct heat, relocate the steaks to indirect heat until they reach desired doneness. Remove steaks and tent with foil; rest for 10 minutes before slicing.
  5. Caramelize Onions: Place a cast iron skillet on the grill over direct heat. Add a few tablespoons of butter to the skillet; when melted, add the thinly sliced sweet onions. Cook the onions, stirring occasionally, until caramelized, about 15 minutes.
  6. Assemble Sliders: Preheat the oven to broil and line a baking sheet with parchment paper. Separate slider buns and brush the insides with the remaining cowboy butter. Layer Havarti cheese onto both the top and bottom buns. Place caramelized onions on the bottom buns, then add a few strips of sliced steak on top. Broil the assembled bottoms for 1-2 minutes or until cheese begins to melt. Place the top buns over the steak, slice sliders individually, and serve immediately.

Notes

  • For best flavor, use ribeye or sirloin steaks, but filet mignon works well too.
  • Adjust cayenne and red pepper flakes to control the spiciness of the cowboy butter.
  • Allowing the steak to rest after cooking ensures juicy, tender meat.
  • Caramelizing onions slowly over medium heat develops their natural sweetness; do not rush this step.
  • Use neutral oil with a high smoke point, like canola or grapeseed oil, to sear steaks.
  • Slider buns can be toasted lightly on the grill for additional texture if desired.
