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 the softened butter with minced garlic, chopped parsley, chives, thyme leaves, lemon juice, Dijon mustard, smoked paprika, red pepper flakes, garlic powder, and onion powder. Mix thoroughly until all ingredients are well incorporated. Season with salt and pepper to taste. Cover and chill in the refrigerator for at least 30 minutes to allow flavors to meld.
- Prepare the Steak: Pat the sirloin steak slices dry using paper towels to remove excess moisture. Season generously on both sides with salt and freshly ground black pepper to enhance flavor and aid in browning during cooking.
- Cook the Steak: Heat olive oil in a large skillet over medium-high heat until shimmering. Working in batches to avoid overcrowding, sear the steak slices for about 1 to 2 minutes per side. Cook until the internal temperature reaches your preferred doneness—130-135°F for medium-rare or 135-145°F for medium. The quick searing locks in juices and develops a flavorful crust.
- Rest the Steak: Remove the cooked steak slices from the skillet and let them rest on a plate for a few minutes. Resting allows the juices to redistribute throughout the meat, resulting in tender, juicy bites.
- Assemble the Sliders: Split the slider buns and spread a generous layer of the chilled Cowboy Butter on both the top and bottom halves. Place the rested steak slices onto the bottom halves of the buns. If desired, add a slice of provolone cheese and a spoonful of caramelized onions for extra richness and sweetness. Top with an additional dollop of Cowboy Butter and close the sliders.
- Serve: Serve the sliders immediately while the steak is warm and the butter flavorful. These sliders are perfect for parties, game days, or casual gatherings.
Notes
- For best flavor, allow the Cowboy Butter to chill and develop in the fridge for at least 30 minutes before using.
- Adjust red pepper flakes in the butter to control the spiciness to your preference.
- Use a meat thermometer to accurately check steak doneness for optimal results.
- Caramelized onions add sweetness but can be omitted for a simpler slider.
- These sliders can be made ahead by preparing the butter and steak in advance and assembling just before serving.
- Store leftover Cowboy Butter covered in the refrigerator for up to 1 week.
