Cowboy Butter Steak Sliders: The Ultimate Flavor-Packed Bites Recipe - Recipe Image

Ingredients

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
1.5 pounds sirloin steak, or your favorite cut for sliders (flank steak or ribeye also work well)
2 tablespoons olive oil
Salt and freshly ground black pepper to taste
1 teaspoon garlic powder
1 teaspoon onion powder
12 slider buns, split
4 ounces provolone cheese, sliced (or your favorite cheese)
Optional toppings: caramelized onions, arugula, sliced tomatoes

Instructions

Step 1: Prepare the Cowboy Butter by combining the softened butter, minced garlic, parsley, chives, thyme, lemon juice, Dijon mustard, smoked paprika, red pepper flakes, garlic powder, and onion powder in a medium bowl. Mix well and season with salt and pepper to taste. Chill for at least 30 minutes if time allows.
Step 2: Pat the steak dry with paper towels. Mix salt, pepper, garlic powder, and onion powder in a small bowl, then sprinkle generously over both sides of the steak.
Step 3: Heat olive oil in a large cast-iron skillet over medium-high heat. Sear the steak for 3-4 minutes per side for medium-rare, or cook longer to reach your preferred doneness. Use a meat thermometer to check the internal temperature.
Step 4: Remove the steak from the skillet and let it rest for at least 10 minutes, tented loosely with foil. Then slice the steak thinly against the grain.
Step 5: Lightly toast the slider buns. Spread a generous amount of Cowboy Butter on both halves of each bun. Place a slice of provolone cheese on the bottom half, then top with sliced steak and any optional toppings. Add an extra dollop of Cowboy Butter on top of the steak if desired. Close each slider with the top bun.
Step 6: Serve the sliders immediately for the best flavor and texture.

Tips & Variations

For a smoky depth, use smoked sea salt in the Cowboy Butter instead of regular salt.
Try swapping provolone for cheddar or pepper jack for a spicy twist.
If you want milder sliders, reduce or omit the red pepper flakes in the butter.
Use leftover steak for an easy slider prep; reheat slices gently to avoid toughness.
Add caramelized onions or arugula for extra sweetness and peppery bite.

Storage

Store leftover sliders in an airtight container in the refrigerator for up to 2 days. To reheat, warm gently in a skillet or oven to keep the bread from getting soggy and the steak tender. The Cowboy Butter can be refrigerated for up to a week; bring it to room temperature before spreading.

How to Serve

Serve this delicious recipe with your favorite sides.

FAQs

Can I use other types of steak for these sliders?

Yes, flank steak, ribeye, or even flat iron steak work well. Choose cuts that are tender and flavorful, and adjust cooking times accordingly.

Is it necessary to chill the Cowboy Butter before using?

Chilling the butter allows the flavors to meld and the texture to firm up, making it easier to spread. However, you can use it immediately if short on time.

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

1.5 pounds sirloin steak (or flank steak, ribeye)
2 tablespoons olive oil
Salt and freshly ground black pepper to taste
1 teaspoon garlic powder
1 teaspoon onion powder

Assembly

12 slider buns, split
4 ounces provolone cheese, sliced
Optional toppings: caramelized onions, arugula, sliced tomatoes

Instructions

Prepare 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 until well blended. Season with salt and freshly ground black pepper to taste. Chill the mixture for at least 30 minutes to allow the flavors to meld, though this step is optional.
Prepare the Steak: Pat the steak dry thoroughly using paper towels to ensure a good sear. In a small bowl, mix salt, black pepper, garlic powder, and onion powder. Generously sprinkle this seasoning blend evenly over both sides of the steak.
Sear the Steak: Heat olive oil in a large cast-iron skillet over medium-high heat until shimmering. Place the steak in the skillet and sear for 3 to 4 minutes on each side for medium-rare doneness. Adjust timing if you prefer your steak cooked more or less. Use a meat thermometer — medium-rare is about 130–135°F (54–57°C) internal temperature.
Rest and Slice the Steak: Remove the steak from the skillet and transfer to a cutting board. Tent loosely with foil and let it rest for at least 10 minutes to allow the juices to redistribute, ensuring tender slices. Then, slice the steak thinly against the grain for maximum tenderness.
Assemble the Sliders: Lightly toast the split slider buns until golden. Spread a generous layer of Cowboy Butter on both the top and bottom halves of each bun. Place a slice of provolone cheese on the bottom half, followed by a portion of sliced steak. Add any optional toppings such as caramelized onions, arugula, or sliced tomatoes if desired. For extra flavor, add a dollop of Cowboy Butter atop the steak. Finish by placing the top bun on each slider.
Serve: Serve the sliders immediately while warm to enjoy the contrast of melted cheese, flavorful steak, and creamy Cowboy Butter. These sliders are perfect for game day, parties, or casual meals.

Notes

The steak can be substituted with flank or ribeye depending on preference or availability.
Chilling the Cowboy Butter allows the flavors to develop more intensely, but the sliders are delicious even if served immediately.
Adjust red pepper flakes in the butter to control the heat level.
For added sweetness, caramelized onions are a great topping choice.
These sliders can be made ahead by preparing the butter and steak, then assembling just before serving.
