Featured in Perfect Finger Foods for Every Occasion.

These Cowboy Butter Steak Sliders transform simple ingredients into a gourmet appetizer or main course. The star of this recipe is the flavorful cowboy butter - a compound butter infused with garlic, lemon, herbs, and spices that adds layers of flavor to both the steak and the buns. Perfectly grilled steak gets brushed with this butter while cooking, then is paired with sweet caramelized onions and melty havarti cheese, all nestled between slider buns that have been brushed with more of the aromatic butter and briefly broiled. The combination of textures and flavors - from the tender meat to the sweet onions, creamy cheese, and the punch of the zesty butter - creates a bite that's far greater than the sum of its parts. Whether served as party appetizers or a family dinner, these sliders deliver restaurant-quality taste with home-cooked charm.

These Cowboy Butter Steak Sliders deliver an irresistible combination of juicy tenderloin, zesty herb-infused butter, and melty havarti cheese on soft slider buns. Perfect for entertaining or a special family dinner, these handheld sandwiches elevate the humble slider to gourmet status.

Last month, I served these at a small backyard gathering, and my neighbor who's usually reserved with compliments declared them 'the best sliders I've ever had.' The secret? The cowboy butter, which infuses every element with fresh, aromatic flavor.

Essential Ingredients and Selection Tips

  • Quality Steak: Splurge on tenderloin or ribeye for the most tender results
  • Havarti Cheese: Mild and perfectly melty; Fontina works well too
  • Fresh Herbs: Don't substitute dried; fresh parsley, thyme, and chives are essential
  • Slider Buns: King's Hawaiian provides the perfect sweet-savory balance
  • Fresh Lemon: Both juice and zest brighten all the flavors

The magic happens when the herb-infused cowboy butter gets applied to both the steak during cooking and the buns before broiling, creating layers of flavor throughout the entire slider.

Detailed Cooking Instructions

Step 1: Prepare Your Ingredients
Trim any excess fat and silver skin from your choice of premium steak. Rub with a light coating of oil, then season generously with kosher salt and freshly cracked black pepper on all sides. For thicker cuts, use more seasoning. Wrap in plastic and refrigerate for a few hours to allow the seasoning to penetrate the meat.
Step 2: Create the Cowboy Butter
In a small saucepan over low heat, melt butter while whisking continuously. Add fresh lemon juice, lemon zest, minced garlic, a small dollop of Dijon mustard, cayenne pepper, red pepper flakes, fresh thyme, and paprika. Remove from heat once combined, then stir in freshly chopped chives and parsley. Season with salt and pepper to taste.
Step 3: Prepare for Grilling
Preheat your grill to medium-high heat, creating zones for both direct and indirect cooking. Remove steaks from the refrigerator and let them rest at room temperature for about 30 minutes before grilling. This step ensures more even cooking.
Step 4: Grill the Steaks
Place steaks over direct heat for about 2-3 minutes per side, being careful not to char them. Space them slightly apart to ensure each piece gets crispy. Resist the urge to stir-fry—let them develop a crust before turning.
Step 5: Achieve the Perfect Crisp
After 5-6 minutes of total cooking time, move steaks to the indirect heat zone and continue cooking until they reach an internal temperature of 130-135°F. This step ensures they remain juicy while achieving a beautiful crust.
Step 6: Prepare the Buns
While the steaks cook, prepare the slider buns. Slice King's Hawaiian rolls in half lengthwise, then spread a thin layer of cowboy butter on the inside of each bun. This step creates a moisture barrier that prevents sogginess.
Step 7: Assemble the Sliders
Place a generous spoonful of caramelized onions on the bottom bun, followed by a layer of sliced steak. Top with havarti cheese and a sprinkle of fresh chives. Place the top bun on and gently press down to seal the slider.
Step 8: Broil the Sliders
Place assembled sliders on a baking sheet lined with parchment paper. Broil under the preheated broiler for 1-2 minutes, until the cheese is fully melted and the tops are golden brown. Keep a close eye to prevent burning.
Step 9: Rest and Serve
Allow the sliders to rest for 2-3 minutes before serving. This step allows the flavors to meld and the cheese to set slightly, making them easier to handle.
Step 10: Enjoy!
Serve immediately while hot and crispy. Pair with a simple green salad dressed with lemon vinaigrette for balance.

I learned the importance of letting the steak rest after my first attempt resulted in steaks that weren't quite as tender as I hoped. Taking that extra time makes all the difference in the final texture.

Family-Friendly Adaptations

For households with varying tastes, this recipe offers easy customization. Create a small portion of cowboy butter without the heat elements for spice-sensitive family members. For children who might be hesitant about steak, start with just slider buns in their cowboy butter, gradually introducing more aromatic notes as they become accustomed to the flavors. My nephew who 'doesn't like spicy food' happily devours the mild version while adults can add chili oil to their individual portions.

Seasonal Serving Suggestions

This versatile slider welcomes seasonal produce throughout the year. Summer brings opportunities for fresh corn salad or watermelon. Fall calls for roasted sweet potatoes or Brussels sprouts. Winter versions incorporate hearty root vegetables. Spring welcomes asparagus or fresh green salads. The adaptability keeps this dish exciting year-round while making use of what's available.

Make-Ahead and Freezer Tips

For busy households, this recipe shines as a prepare-ahead solution. The cowboy butter can be made up to three days ahead and refrigerated - simply bring to room temperature before using. Caramelized onions can be prepared a day ahead and refrigerated. While the steak is best cooked shortly before serving, you can prepare and season it up to 24 hours in advance and refrigerate until ready to grill.

Chef's Essential Tips

  • For extra flavor, add a teaspoon of Worcestershire sauce to the cowboy butter
  • Toast the slider buns lightly before assembly if they're a day old
  • Add a pinch of cayenne to the cowboy butter for a spicy kick
  • For a thicker sauce, simmer for 5-10 minutes to reduce
  • Leftovers will stay good in the refrigerator for up to 3 days or frozen for 3 months

I discovered these refinements over many iterations of this dish - particularly the Worcestershire sauce addition, which adds remarkable depth to the cowboy butter without being identifiable as Worcestershire.

This elevated slider has become my reliable go-to when I need a quick yet impressive meal. The combination of premium ingredients and the flavor-packed cowboy butter creates something greater than the sum of its parts - a dish that feels indulgent while being surprisingly simple to prepare.

Frequently Asked Questions

→ Can I make the cowboy butter ahead of time?
Absolutely! You can prepare the cowboy butter up to a week in advance and store it in the refrigerator. Bring it to room temperature before using. You can also freeze it for up to 3 months in an airtight container.
→ What's the best cut of steak to use for these sliders?
Ribeye offers great marbling and flavor, while tenderloin (filet) is the most tender. Sirloin provides a good balance of flavor and tenderness at a more affordable price. Choose based on your preference and budget.
→ Can I use another type of cheese instead of havarti?
Yes! Provolone, white cheddar, Swiss, or Gruyère would all work beautifully. Look for a cheese that melts well and complements the rich flavors of the steak and cowboy butter.
→ How do I know when my steak is cooked to the right temperature?
For medium-rare sliders, aim for an internal temperature of 130-135°F. For medium, 135-145°F is ideal. Remember that the steak will continue to cook slightly while resting, so remove it from heat about 5 degrees before your target temperature.
→ Can I make these sliders without a grill?
Yes! The recipe includes instructions for cooking the steak in a cast iron skillet. This method works just as well and is perfect for when outdoor grilling isn't an option.

Ingredients

→ FOR THE SLIDERS

01 1 1/2 pounds boneless steak such as ribeye, filet, sirloin
02 neutral oil as needed
03 kosher salt to taste
04 freshly cracked black pepper to taste
05 3 sweet onions, thinly sliced
06 9 slider buns
07 3/4 pound sliced havarti cheese

→ FOR THE COWBOY BUTTER

08 1 stick unsalted butter, at room temperature
09 4 garlic cloves, minced
10 1/2 lemon, zested and juiced
11 1 tablespoon dijon mustard
12 1 teaspoon paprika
13 1/2 teaspoon cayenne
14 1/2 teaspoon dried thyme
15 1 teaspoon red pepper flakes
16 1 tablespoon chives, minced
17 2 tablepoons fresh parsley, minced
18 kosher salt and pepper to taste

Instructions

Step 01

Prepare steaks by trimming excess fat and silver skin if needed. Rub with oil and season your steaks well on all sides with kosher salt and freshly cracked black pepper. If steaks are thicker, be sure to season more heavily. Wrap steaks in plastic wrap and place in the fridge for a few hours for optimum seasoning penetration.

Step 02

In a saucepan over low heat, melt the butter and whisk continually. Add lemon juice and zest, garlic, dijon, and dry seasonings. Remove from heat and add chives and fresh parsley. Salt and pepper to taste. Spoon out a few tablespoons into a small bowl for use on the steaks as they grill. Set aside the remaining butter for slider buns.

Step 03

Preheat grill to medium-high with an indirect heat zone. Remove steaks from the fridge and allow them to rest at room temp for 30 minutes. Cook steaks over direct heat for about 2-3 minutes per side, being sure not to char them. If high flames appear, move them to indirect heat until flame subsides. Brush both sides with cowboy butter as they cook. After 5-6 minutes of total cook time, move the steaks to indirect heat until desired temperature is reached. Remove and allow steaks to rest on a plate with tented foil for 10 minutes before slicing.

Step 04

Place a cast iron skillet on the grill over direct heat. Add a few tablespoons of butter into the skillet, once it melts add the sliced onions. Allow onions to cook until caramelized, stirring occasionally, about 15 minutes.

Step 05

Pre-heat oven to broil. Line a baking sheet with parchment paper. Separate the sliders and brush the inside of the slider buns with all remaining cowboy butter. Add the havarti cheese to the top and bottom buns then add the grilled onions to the bottom buns. Place a few strips of sliced steak per bottom slider. Broil for 1-2 minutes or until cheese begins to melt. Place the top sliders over the steak, slice and enjoy!

Notes

  1. Alternative method using a cast iron skillet is provided in the notes
  2. For the cast iron method, use avocado oil due to its high smoke point
  3. Allow steaks to rest before slicing for juicier results
