Ingredients
Scale
Cowboy Butter
- 1 cup (2 sticks) unsalted butter, softened
- 4 cloves garlic, minced
- 1/4 cup fresh parsley, chopped
- 2 tablespoons fresh chives, chopped
- 1 tablespoon fresh thyme leaves
- 1 tablespoon lemon juice
- 1 teaspoon Dijon mustard
- 1 teaspoon smoked paprika
- 1/2 teaspoon red pepper flakes (adjust to taste)
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- Salt and freshly ground black pepper to taste
Steak and Assembly
- 1.5 lbs sirloin steak, cut into 1/4-inch thick slices
- 2 tablespoons olive oil
- Salt and freshly ground black pepper to taste
- 12 slider buns, split
- Optional: Provolone cheese slices
- Optional: Caramelized onions
Instructions
- Make the Cowboy Butter: In a medium bowl, combine softened butter, minced garlic, parsley, chives, thyme, lemon juice, Dijon mustard, smoked paprika, red pepper flakes, garlic powder, and onion powder. Mix well until all ingredients are fully incorporated. Season with salt and freshly ground black pepper to taste. Cover the bowl and chill the butter for at least 30 minutes to develop the flavors.
- Prepare the Steak: Pat the sirloin steak slices dry using paper towels to remove any excess moisture. Season the slices generously on both sides with salt and freshly ground black pepper, ensuring even coverage for optimal flavor.
- Cook the Steak: Heat olive oil in a large skillet over medium-high heat. Once the oil is shimmering, add the steak slices in batches to avoid overcrowding. Sear each slice for 1 to 2 minutes per side until cooked to your desired level of doneness—130-135°F for medium-rare or 135-145°F for medium. Avoid overcooking to keep the steak tender and juicy.
- Rest the Steak: Remove the cooked steak slices from the skillet and place them on a plate. Let them rest for a few minutes, allowing the juices to redistribute throughout the meat for enhanced tenderness and flavor.
- Assemble the Sliders: Split each slider bun in half. Spread a generous amount of the chilled Cowboy Butter on both halves of every bun. Layer steak slices on the bottom half of each bun. If desired, add provolone cheese slices and caramelized onions for extra richness and sweetness. Finish by adding a dollop of Cowboy Butter on top before closing the sliders with the bun tops.
- Serve: Arrange the assembled sliders on a serving platter and serve immediately to enjoy the full burst of fresh and savory flavors. These sliders make a fantastic appetizer or main dish at any gathering.
Notes
- For best flavor, chill the Cowboy Butter for at least 30 minutes before using.
- Adjust red pepper flakes to control the heat level of the butter according to personal preference.
- To make caramelized onions, slowly cook sliced onions in a bit of oil or butter over low heat until golden and sweet, about 20-30 minutes.
- Use a meat thermometer to check steak doneness to avoid overcooking.
- Sliders are best served fresh but can be kept warm in a low oven for a short time if needed.
- Feel free to swap provolone cheese with your favorite melting cheese like cheddar or Swiss.
