How to Make Cowboy Butter Steak Sliders Recipe
Step 1: Make the Cowboy Butter
Start by combining the softened butter with minced garlic, fresh parsley, chives, thyme, lemon juice, Dijon mustard, smoked paprika, red pepper flakes, garlic powder, and onion powder in a medium bowl. Mix everything thoroughly until you achieve a smooth, uniform butter bursting with herbs and spices. Taste and season with salt and freshly ground pepper to your preference. Place the butter in the fridge to chill for at least 30 minutes; this step helps the flavors meld beautifully while making the butter easy to spread later on.
Step 2: Prepare the Steak
Take your sirloin steak slices and pat them dry with paper towels. This crucial step ensures better searing by reducing moisture. Season each slice generously with salt and freshly ground black pepper on both sides. Don’t be shy with the seasoning here, as it will elevate your steaks to steakhouse quality.
Step 3: 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. Aim for a perfect medium-rare temperature around 130-135°F, or cook slightly longer if you prefer medium. The goal is to get a nice crust on the outside while keeping the center tender and juicy. Once cooked, transfer the steak to a plate and let it rest briefly to retain all its flavorful juices.
Step 4: Assemble the Sliders
Split the slider buns in half horizontally. Spread a generous layer of the chilled cowboy butter on both the top and bottom halves of the buns. On the bottom half, layer the warm steak slices, followed by a slice of provolone cheese if you’re using it, and a spoonful of those sweet caramelized onions for that irresistible contrast. Top each slider with another dollop of cowboy butter, then close your buns and get ready to enjoy.
Step 5: Serve Immediately
These sliders are best enjoyed fresh off the assembly line, while the steak is warm and the cowboy butter melts into a rich, silky sauce. Serve them right away for that perfect hot, juicy experience that will have everyone asking for seconds.
How to Serve Cowboy Butter Steak Sliders Recipe

Garnishes
For a bit of flair and added freshness, consider topping your sliders with extra chopped parsley or chives. A light sprinkle of crispy fried onions adds crunch and contrast to the tender steak, while a squeeze of fresh lemon over the top brightens each bite. These small touches make the sliders feel extra special and visually inviting.
Side Dishes
Classic sides are perfect companions for your Cowboy Butter Steak Sliders. Think crispy French fries, crunchy coleslaw, or even a smoky baked bean salad to stay in the cowboy spirit. If you want something lighter, a refreshing cucumber or tomato salad balances the richness beautifully. Whatever you pick, these sliders stand strong as the star of the meal.
Creative Ways to Present
Hosting a party? Arrange the sliders on a rustic wooden board or a cast-iron skillet for dramatic, western-themed presentation. You can stick in little cocktail picks topped with mini American flags or rustic twine for extra charm. Adding small bowls of extra cowboy butter or dipping sauces nearby invites guests to customize each bite, making the meal interactive and fun.
Make Ahead and Storage
Storing Leftovers
If you happen to have any leftover sliders, store them in an airtight container in the refrigerator for up to 3 days. To keep the buns from getting soggy, consider keeping the assembled sliders separate from any extra cowboy butter or caramelized onions and add these fresh when reheating.
Freezing
While fresh is always best, you can freeze the cooked steak slices alone, wrapped tightly in plastic wrap and placed in a freezer-safe bag for up to 2 months. Avoid freezing assembled sliders as the buns tend to get mushy upon thawing. Thaw steak overnight in the fridge before reheating and assembling your sliders.
Reheating
To reheat, gently warm the steak slices in a skillet over low heat just until warmed through; this helps avoid drying them out. Warm your slider buns separately in a toaster oven or on a grill pan. Then reassemble with fresh cowboy butter to bring back that irresistible richness and freshness you loved the first time around.
FAQs
Can I use a different cut of steak for this recipe?
Absolutely! While sirloin is perfect for its tenderness and flavor, you can use ribeye or flank steak sliced thinly as well. Just adjust the cooking time to avoid overcooking tougher cuts.
What can I substitute for fresh herbs if I don’t have them?
You can use dried herbs, but use about one-third of the amount since dried herbs are more concentrated. Fresh herbs really enhance the flavor here, so consider grabbing them for best results when possible.
Is it okay to make the cowboy butter a day ahead?
Yes! Making the cowboy butter a day ahead actually allows the flavors to deepen beautifully. Just keep it well covered and refrigerated until you’re ready to use.
How spicy is this recipe? Can I adjust the heat?
This recipe has a mild to medium heat from the red pepper flakes, but you can easily adjust this based on your preference. Omit the flakes for no heat or add more for a fiery kick.
Can these sliders be made vegetarian or vegan?
For a vegetarian twist, use grilled portobello mushrooms in place of steak and prepare a vegan butter substitute with plant-based butter and herbs. While it won’t be a classic steak slider, it’ll still be delicious and rich in flavor!

Ingredients
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.
