The ingredients for this recipe are straightforward but each one plays an essential role in building layers of texture and flavor, from the sweet slider buns to the fresh herbs in the cowboy butter. Here’s what you’ll want to gather:

Kings Hawaiian sweet slider buns: Their sweetness balances the savory steak and spicy butter perfectly.
16 oz ribeye steak: The star protein, known for its marbling and rich flavor.
Steak seasoning or salt, pepper, garlic powder: Simple seasoning to enhance the steak’s natural taste.
6 slices cheddar cheese: Melts beautifully over the steak for ooey-gooey goodness.
2 yellow onions: Thinly sliced and caramelized for a sweet, soft texture.
2 tablespoons olive oil: Used to caramelize the onions without burning.
1 teaspoon salt: For seasoning the onions and steak.
1 teaspoon pepper: Adds a mild heat and depth.
1 teaspoon sugar: Helps the onions caramelize to golden perfection.
1/2 stick softened butter: The base for the cowboy butter, creamy and rich.
1 tablespoon garlic paste: Infuses the butter with a bold, savory punch.
1 tablespoon Dijon mustard: Adds zing and tang for balance.
1/2 teaspoon smoked paprika: Lends a subtle smoky note to the butter.
2 tablespoons chopped parsley: Brings fresh, herbal brightness.
1 tablespoon minced thyme: Earthy flavor that complements beef.
1 tablespoon prepared horseradish: Adds a spicy kick to the butter.
1/2 teaspoon crushed red pepper flakes: For a little heat to wake up your palate.
Juice from half a lemon: Adds brightness and acidity to the butter.
1/2 teaspoon salt and 1/2 teaspoon black pepper: Finishing seasoning for the cowboy butter.

Directions

Step 1: Start by caramelizing your onions. Thinly slice the yellow onions, then add them to a skillet with 2 tablespoons of olive oil over medium-low heat. Season with 1 teaspoon salt, 1 teaspoon pepper, and 1 teaspoon sugar. Stir regularly and let them slowly cook down for 20 to 30 minutes until they turn soft, sweet, and golden brown. This step takes patience, but the results are ridiculously worth it. Once done, set the onions aside.

Step 2: Next, prepare your ribeye steak. Season it evenly with your chosen steak seasoning or simply salt, pepper, and garlic powder to taste. Grill the steak over medium-high heat until the internal temperature reaches 130°F for medium-rare, about 4 to 5 minutes per side depending on thickness. Once cooked, let the steak rest for 10 minutes so the juices redistribute and slicing becomes easier.

Step 3: While the steak rests, mix your cowboy butter. In a small bowl, combine softened butter, garlic paste, Dijon mustard, smoked paprika, chopped parsley, minced thyme, prepared horseradish, crushed red pepper flakes, lemon juice, salt, and black pepper. Stir well until everything is evenly incorporated. This butter is what makes these sliders truly special and bursting with flavor.

Step 4: Slice the rested steak thinly against the grain to keep it tender. Then start assembling your sliders by layering cheddar cheese on the bottom half of each Hawaiian slider bun, followed by a generous layer of the caramelized onions, then the sliced steak. Top each with a few spoonfuls of cowboy butter spreading evenly over the steak. Place the top buns on and brush the outside of the buns with any remaining cowboy butter for extra richness.

Step 5: Finally, bake the assembled sliders in a preheated oven at 350°F for about 15 minutes. The goal here is to toast the buns lightly and melt the cheddar cheese throughout all the layers. When done, take them out, slice into individual sliders, and serve immediately while warm and melty.

Servings and Timing

This Ribeye Steak Sliders with Cowboy Butter Recipe yields about 6 hearty sliders, perfect for a small group or family meal. Preparation time is approximately 15 minutes if your onions are already sliced. The caramelizing of onions takes the longest—around 20 to 30 minutes—but this can be done ahead of time. Grilling the steak and assembling the sliders will take around 15 minutes combined. Baking the sliders to finish requires another 15 minutes. Altogether, expect about 45 minutes from start to finish, including a 10-minute resting time for the steak.

How to Serve This Ribeye Steak Sliders with Cowboy Butter Recipe

A tray of eight small sandwiches arranged in two rows on parchment paper inside an oven is shown. Each sandwich has three layers: a soft golden-brown round top bun with specks of herbs, a middle layer with thick slices of grilled meat showing a pinkish interior, and a bottom layer of melted orange cheese and caramelized onions on a lighter toasted bun. The warm lighting highlights the shiny surface of the buns and the melted cheese oozing slightly on the sides. The tray rests on a metal oven rack inside a dark oven with a white marbled texture visible beneath. Photo taken with an iphone --ar 4:5 --v 7

I love serving these sliders fresh and warm because the melted cheese and cowboy butter are at their most indulgent when hot. They pair beautifully with classic hearty sides—think crispy fries, onion rings, or a fresh green salad with a tangy vinaigrette to cut through the richness. For something a bit lighter, roasted vegetables or a slaw with a vinegar-based dressing add a lovely crunch and brightness.

When it comes to presentation, I like to garnish the sliders with a sprinkle of fresh parsley or thyme on top for a pop of color and a hint of herbaceous aroma. Serving them on a rustic wooden board alongside small bowls of extra cowboy butter for dipping adds a fun, informal vibe perfect for casual dinners or weekend gatherings.

For drinks, I highly recommend something that complements the smoky and creamy notes of the sliders. A medium-bodied red wine like a Malbec or Zinfandel works wonderfully, as does a well-balanced craft beer like an amber ale. If you prefer non-alcoholic options, a sparkling lemonade or iced tea with lemon really refreshes the palate. These sliders also shine at parties, game days, or even special holiday meals where you want a playful, crowd-pleasing main dish that everyone will rave about.

Variations

I often experiment with variations to keep this Ribeye Steak Sliders with Cowboy Butter Recipe fresh and exciting. For example, if you want to switch up the protein, flank steak or sirloin work well though the ribeye’s marbling really makes a difference in juiciness. For a slightly different flavor, swapping cheddar for pepper jack or a smoked gouda adds a little twist.

If you’re catering to dietary needs, you can make this recipe gluten-free by using gluten-free slider buns or even hearty lettuce wraps instead of bread. Vegan versions are a bit more challenging, but you could try a plant-based steak alternative with a vegan butter spread made from olive oil and vegan mayo combined with herbs and spices similar to the cowboy butter components.

For cooking methods, while I love grilling the ribeye for that signature smoky char, you can also sear it in a cast-iron skillet and finish it in the oven if grilling isn’t an option. Additionally, playing with the spice levels in the cowboy butter or adding a touch of honey can tailor the sliders to your exact taste preferences. This recipe is flexible, and I encourage you to make it your own!

Storage and Reheating

Storing Leftovers

Leftover sliders store wonderfully in an airtight container in the refrigerator for up to 3 days. I recommend storing the slider buns separately from the steak and toppings if possible to avoid sogginess. Otherwise, place the fully assembled sliders tightly wrapped in foil or plastic wrap. Using shallow containers helps maintain their shape and texture.

Freezing

If you want to freeze these sliders, it’s best to assemble them without the cowboy butter to prevent separation and texture changes. Wrap each slider individually in plastic wrap, then place them in a freezer-safe bag or container. They keep well for up to 2 months. When ready to enjoy, thaw them overnight in the refrigerator before reheating.

Reheating

To reheat leftover or thawed sliders, I prefer using the oven at 325°F for about 10-15 minutes to gently warm the meat and melt the cheese without drying them out. Microwaving is quicker but can make the buns soggy, so if you must microwave, do it in short bursts with a paper towel to absorb moisture. Adding a fresh spoonful of cowboy butter after reheating revitalizes the flavors beautifully.

FAQs

What is cowboy butter and why is it used in this recipe?

Cowboy butter is a flavorful compound butter made from softened butter mixed with garlic, herbs, spices, mustard, horseradish, and lemon juice. It’s used in this recipe to add a rich, tangy, and slightly spicy kick that enhances the natural flavor of the ribeye steak and balances the sweetness of the buns and onions perfectly.

Can I use a different cut of steak instead of ribeye?

Absolutely! While ribeye is my favorite due to its marbling and tenderness, you can substitute sirloin, flank steak, or even strip steak. Just be mindful that leaner cuts may cook faster and be less juicy, so adjust your cooking time and rest period accordingly to maintain tenderness.

Is it possible to make these sliders ahead of time?

You can definitely prepare some components ahead, especially the caramelized onions and cowboy butter, which can be stored in the fridge separately for several days. The steak is best cooked close to serving time to enjoy maximum freshness, but leftovers store well for quick reheating.

How spicy is the cowboy butter, and can I adjust it?

The cowboy butter has a mild to medium heat level thanks to the horseradish and crushed red pepper flakes. If you prefer less spice, simply reduce or omit the red pepper flakes and horseradish. For a bolder kick, add more according to your taste. It’s very customizable!

What sides pair well with these sliders for a complete meal?

I love pairing these sliders with crispy fries, onion rings, or a vibrant green salad to add freshness. Roasted vegetables or a tangy slaw also make excellent accompaniments. For drinks, a robust red wine, craft beer, or sparkling lemonade rounds out the meal wonderfully.
