Ingredients You’ll Need
The magic of Cowboy Butter Steak Sliders Recipe really comes from combining classic ingredients that complement each other perfectly. When shopping, I always look for fresh, high-quality beef sirloin and brioche rolls with a soft, buttery texture to get the best results.

- Yellow onion: Thinly sliced for perfect caramelization that brings sweetness and richness.
- Jalapeño pepper: Adds a mild heat that balances the savory steak and buttery rolls.
- Sharp cheddar cheese: Melts just right and brings a tangy contrast to the richness.

How to Make Cowboy Butter Steak Sliders Recipe
Step 1: Season and Rest the Steak
Start by seasoning your beef sirloin generously with kosher salt and black pepper. I like to let the steak rest at room temperature for about 30 minutes before cooking—it helps the meat cook more evenly and keeps it juicy, which makes a big difference in the final slider.
Step 2: Caramelize the Onions
While the steak is resting, caramelize your onions in a skillet over medium-low heat with two tablespoons of butter. This takes patience—about 25 to 30 minutes—but those sweet, golden onions are a game changer. Remember to stir occasionally so they don’t burn, and you’ll be rewarded with deep flavor and beautiful color.
Step 3: Cook the Steak
Once your onions are done, crank the heat to medium-high and melt the last tablespoon of butter in the same skillet. Add the steak and cook for 4 to 5 minutes per side. I usually use a meat thermometer to check for my preferred doneness—medium-rare is my favorite for sliders. Spoon the melted butter over the steak while it cooks for extra richness.
Step 4: Slice the Steak Thinly
After cooking, let the steak rest for about 5 minutes—this locks in the juices. Then, slice it as thin as possible against the grain. Thin slices are key; they fit perfectly on each slider and make every bite tender and flavorful.
Step 5: Assemble and Bake the Sliders
Grab your brioche rolls and split them in half horizontally. Place the bottom halves in a sprayed baking dish and drizzle about a quarter cup of melted cowboy butter over them. Layer on the steak slices, jalapeño slices, shredded cheddar, and caramelized onions. Then top with the remaining roll halves, brush their tops generously with the remaining melted cowboy butter, cover with foil, and bake at 350°F for 15 minutes. Finish under the broiler for a few minutes until golden and bubbly.
Pro Tips for Making Cowboy Butter Steak Sliders Recipe
- Rest Your Meat: I learned the hard way that skipping the resting time makes the steak juices run out when sliced—give it a solid 5 minutes!
- Slice Against the Grain: This simple trick keeps every bite tender, especially important on a rich, buttery slider.
- Don’t Rush the Onions: Caramelizing is slow but essential; it adds sweetness that balances the spicy and savory elements perfectly.
- Butter Is Your Friend: Using plenty of cowboy butter throughout the process keeps these sliders moist and flavorful, so don’t skimp!
How to Serve Cowboy Butter Steak Sliders Recipe
Garnishes
I love topping these sliders with a few fresh sprigs of chopped parsley or a light sprinkle of smoked paprika for color and a hint of warmth. A little extra jalapeño on the side is a great option if you like things spicy!
Side Dishes
These sliders go beautifully with crispy oven fries, a fresh coleslaw, or even a simple green salad. For game day, I like to serve them alongside baked beans and pickles for a classic combo that everyone enjoys.
Creative Ways to Present
For a party, I arrange a platter with the sliders stacked like mini towers and a bowl of extra cowboy butter on the side for dipping. Wrapping each slider with a colorful toothpick adds a festive touch and makes grabbing them mess-free. I once even swapped the brioche for pretzel rolls for a fun twist during Oktoberfest!
Make Ahead and Storage
Storing Leftovers
If you have leftovers, I recommend wrapping the sliders tightly in foil or placing them in an airtight container in the fridge. They reheat beautifully within 2 days, and the flavors just deepen overnight.
Freezing
I’ve frozen fully assembled sliders before by wrapping them tightly and placing them in a freezer bag. When thawed, they heat up nicely, though I prefer freezing the components separately for the freshest texture.
Reheating
To reheat, I remove the foil and warm the sliders in the oven at 350°F for about 10-15 minutes until heated through and cheese is melty. Avoid microwaving to keep the brioche from getting soggy.
FAQs
-
Can I use a different cut of beef for Cowboy Butter Steak Sliders Recipe?
Absolutely! While sirloin is my go-to for its tenderness and flavor, ribeye or flank steak also work well—just adjust cooking times to prevent overcooking. Just make sure the steak is sliced thin against the grain for the best texture.
-
How spicy are these sliders with the jalapeño?
The jalapeños add a mild to medium heat that complements the rich flavors without overpowering them. If you want less spice, remove the seeds before slicing, or for more kick, add extra jalapeños or a dash of hot sauce in the cowboy butter.
-
What’s the best way to make the cowboy butter?
Cowboy butter is usually a mixture of melted butter, garlic, herbs like parsley, lemon juice, and a hint of spice. You can whisk it up quickly on the stove or find pre-made recipes online. I like making a double batch and keeping it refrigerated for other dishes too!
-
Can I prepare these sliders ahead of time?
Yes! You can slice and cook the steak, caramelize the onions, and prepare the cowboy butter in advance. Then, assemble and bake the sliders just before serving to keep everything fresh and warm.

Ingredients
Steak and Seasoning
- 2 pounds beef sirloin, trimmed of fat
- 2 teaspoons kosher salt
- 2 teaspoons black pepper
- 3 tablespoons unsalted butter, divided
Vegetables
- 1 large yellow onion, cut in half, thinly sliced into half-moon shapes
- 1 medium jalapeño pepper, sliced
Cheese and Bread
- 1 cup (113 g) sharp cheddar cheese, shredded
- 1 package (12-count) Brioche slider rolls
Cowboy Butter
- 1 recipe cowboy butter, melted, divided
Instructions
- Season the Steak: Season the 2 pounds of beef sirloin evenly with 2 teaspoons kosher salt and 2 teaspoons black pepper. Allow it to rest at room temperature for about 30 minutes to help it cook more evenly.
- Caramelize the Onions: In a large non-stick skillet over medium-low heat, melt 2 tablespoons of unsalted butter. Add the thinly sliced onions and sauté for 25-30 minutes, stirring occasionally until they become very tender and achieve a rich golden brown color. Remove from skillet and set aside.
- Preheat and Prepare Baking Dish: Preheat your oven to 350°F (175°C). Spray a 9×13-inch baking dish with nonstick cooking spray and set aside.
- Cook the Steak: Using the same skillet on medium-high heat, melt the remaining 1 tablespoon butter. Add the rested steak and cook for 4-5 minutes on each side until cooked to your desired doneness. Spoon the melted butter over the steak while cooking to keep it moist.
- Rest and Slice Steak: Remove the steak from the skillet and let it rest for about 5 minutes to allow juices to redistribute. Then slice the steak thinly against the grain for maximum tenderness.
- Assemble Sliders: Split the brioche slider rolls horizontally. Place the bottom halves into the prepared baking dish. Evenly pour about ¼ cup of the melted cowboy butter over the bottoms. Layer the sliced steak over the buttered rolls. Top with sliced jalapeños and shredded sharp cheddar cheese. Next, evenly distribute the caramelized onions over the cheese. Place the top halves of the rolls on the onions.
- Butter and Bake Sliders: Brush the tops of the rolls with approximately ¼ cup melted cowboy butter. Cover the baking dish with aluminum foil and bake for 15 minutes until the cheese is hot and bubbly.
- Brown the Tops: Remove the foil and bake uncovered for an additional 3-5 minutes or until the slider tops turn a golden brown.
- Final Butter Brush and Serve: Remove sliders from the oven and generously brush the remaining melted cowboy butter over them. Slice apart and serve warm.
Notes
- Steak Doneness Guide: Use a meat thermometer to check internal temperature: 125°F for Rare, 130-135°F for Medium Rare, 140°F for Medium, and 145°F for Medium-Well. Remember steak will continue cooking slightly after removal from heat.
- Caramelizing onions is essential for sweet richness—don’t rush this step.
- You can adjust jalapeño quantity based on preferred heat level.
- If cowboy butter recipe is unavailable, a mixture of melted butter, garlic, herbs, and spices can substitute.
