Ingredients You’ll Need

Each ingredient in this Cowboy Butter Steak Sliders Recipe has its purpose, from juicy, well-seasoned steak to the luscious cowboy butter that ties it all together. Using fresh herbs and real butter really amps up the flavor, and pick a good quality steak for the best results.

• Boneless steak (ribeye, filet, or sirloin): Ribeye or filet work great because they stay tender and juicy—thicker cuts need a little extra seasoning.
• Neutral oil: I use avocado oil here because it withstands the heat well without burning.
• Kosher salt: Essential for bringing out the steak’s natural flavor, don’t skip it.
• Freshly cracked black pepper: Adds just the right amount of bite to balance the richness.
• Sweet onions: Thinly sliced and caramelized, they add an irresistible sweetness that complements the savory steak perfectly.
• Slider buns: Soft but sturdy enough to hold all those juicy fillings without falling apart.
• Havarti cheese: I love Havarti for its buttery, smooth melting quality—it’s mild but flavorful.
• Unsalted butter: The base of the cowboy butter; room temperature so it mixes easily.
• Garlic cloves: Fresh minced garlic gives the cowboy butter a punch of flavor.
• Lemon zest and juice: Adds brightness that cuts through the richness beautifully.
• Dijon mustard: Just a hint for tang and depth in the butter.
• Paprika, cayenne, dried thyme, red pepper flakes: These spices bring warmth and a little kick without overwhelming the palate.
• Chives and fresh parsley: Fresh herbs finish the butter, adding vibrant color and flavor.

Variations

One of my favorite things about the Cowboy Butter Steak Sliders Recipe is how adaptable it is. I often switch up the cheese or play with the spice level in the butter depending on my mood and who I’m cooking for. Feel free to make it your own!

• Spicy variation: When I want some heat, I add a little extra cayenne and red pepper flakes to the cowboy butter. My friends love the bold kick this gives.
• Cheese swaps: Sometimes I use sharp cheddar or pepper jack instead of Havarti to boost the cheesiness and add some zing.
• Vegetarian adaptation: For non-meat eaters, grilled portobello mushrooms with the cowboy butter are a delicious swap that still packs flavor.
• Seasonal twist: In the fall, I mix in some finely chopped roasted red peppers or caramelized apples with the onions for a sweet and savory surprise.

How to Make Cowboy Butter Steak Sliders Recipe

Step 1: Season and Prep the Steak

Start by trimming any excess fat or silver skin off your steak to keep things tender. Then, rub a bit of neutral oil like avocado oil all over and season generously with kosher salt and freshly cracked pepper. If your steak is on the thicker side, don’t be shy with the seasoning—I’ve learned that layering that salt makes all the difference. Wrap the steaks tightly in plastic wrap and pop them in the fridge for a few hours; I find that this little “rest” helps the flavors really sink in.

Step 2: Whip Up the Cowboy Butter

While the steak chills, melt your stick of unsalted butter over low heat in a small saucepan. Keep whisking gently as you add minced garlic, lemon zest and juice, Dijon mustard, and all those fragrant spices—paprika, cayenne, thyme, and red pepper flakes. Take it off the heat and stir in fresh chopped chives and parsley for an herbaceous finish. Scoop out a couple of spoonfuls to use while grilling—this is what really pampers your steak during cooking. The rest you’ll save to brush on the slider buns later, so don’t skip this multi-tasking step!

Step 3: Grill to Perfection

Remove the steaks from the fridge about 30 minutes before grilling so they come to room temperature—that’s key for even cooking. Fire up your grill to medium-high and set up an indirect heat zone. Cook steaks over direct heat just 2-3 minutes per side; you want a nice sear without charred flare-ups, so if flames get too high, slide the steak to indirect heat until things calm down. Don’t forget to brush the steaks with that luscious cowboy butter as they cook—it keeps them juicy and flavorful. After a few minutes on direct heat, move your steak to indirect heat and cook until it hits your preferred doneness. When done, rest the steaks tented with foil for about 10 minutes to lock in the juices.

Step 4: Caramelize the Sweet Onions

While the steak rests, place a cast iron skillet on the grill over direct heat and melt a few tablespoons of butter. Add your thinly sliced sweet onions and let them cook slowly, stirring occasionally. The goal is deep golden caramelization which takes about 15 minutes—don’t rush this step because those sweet onions bring a fantastic contrast to the savory steak and spicy butter.

Step 5: Assemble and Broil Your Sliders

Preheat your oven’s broiler and line a baking sheet with parchment paper. Slice your slider buns in half and generously brush the insides with the remaining cowboy butter. Layer sliced Havarti cheese on both top and bottom buns, spread the caramelized onions on the bottom halves, then top with strips of tender, rested steak. Pop these under the broiler for 1-2 minutes—just long enough to melt the cheese to creamy perfection. Cap the sliders with the top buns and get ready to dig in!

How to Serve Cowboy Butter Steak Sliders Recipe

Garnishes

I like to keep garnishes simple so the flavors shine through. A few fresh chives or a scatter of chopped parsley on top adds color and a touch of freshness. Sometimes I add a light swipe of horseradish cream or a tangy pickled jalapeño slice for a little zing. It’s all about tuning it to your palate and what you enjoy.

Side Dishes

When I serve these sliders, crispy oven-baked fries or sweet potato wedges are my go-to sides. A simple green salad with a bright vinaigrette also balances the richness perfectly. For real game day vibes, throw together a bowl of coleslaw or pickled veggies for some crunch and acidity alongside.

Creative Ways to Present

For special gatherings, I love arranging these sliders on a wooden board and scattering fresh herbs around for that rustic ranch feel. You can also serve them with mini skewers or toothpicks topped with small chili peppers or olives to give guests easy grab-and-go options. It makes the whole presentation inviting and a little festive.

Make Ahead and Storage

Storing Leftovers

After your feast, any leftover steak slices and caramelized onions can go into airtight containers in the fridge for up to 3 days. I store the cowboy butter separately in a small jar so you can refresh your sliders or even melt some over veggies or potatoes later.

Freezing

I’ve frozen leftover cooked steak slices successfully, wrapped tightly in plastic and placed in a freezer-safe bag. They thaw well overnight in the fridge, though the quality is best within a month. For the butter, it freezes beautifully in small containers, so you can make a batch ahead and have it ready to brighten up any meal.

Reheating

To reheat leftover sliders or steak, I gently warm them in a skillet over medium-low heat or pop them in a 300°F oven wrapped in foil to keep the meat tender. Add a dab of cowboy butter on top as they reheat for extra juiciness. Avoid microwaving when possible to prevent drying out.
