Step-by-Step Preparation of Cowboy Butter Steak Sliders
Prepare Your Steak
To kick things off, start with 2 pounds of trimmed beef sirloin. Season it generously with 2 teaspoons of kosher salt and 2 teaspoons of black pepper. These simple seasonings will elevate your steak’s flavor. It's essential to let the seasoned steak rest on the counter for about 30 minutes before cooking. This step allows the salt to penetrate the meat, making it juicy and tender. In the meantime, use this time to prepare your onions.
Caramelize the Onions
Next, let's bring out the magic of caramelized onions! Slice 1 large yellow onion into thin half-moon shapes. In a non-stick skillet over medium-low heat, melt 2 tablespoons of unsalted butter. Once melted, add the onions to the skillet. Allow them to sauté for 25-30 minutes, stirring occasionally. The goal is to achieve a rich golden brown color, which adds sweetness and depth to your Cowboy Butter Steak Sliders. Once they reach perfection, transfer them to a plate and set aside.
Cooking the Steak to Perfection
Now, let’s cook that steak! Preheat your oven to 350°F and prepare a 9x13-inch baking dish by spraying it with nonstick cooking spray. In the same skillet used for onions, melt the remaining 1 tablespoon of butter over medium-high heat. Add the steak, cooking it for 4-5 minutes on each side, or until it reaches your preferred doneness. Remember, the steak will continue to cook slightly once removed from the heat.
A helpful tip: Use a meat thermometer to check your steak's internal temperature (125°F for rare and up to 145°F for medium-well) to ensure it meets your flavor preferences.
Assemble the Sliders
With your steak and onions ready, it’s time to assemble your Cowboy Butter Steak Sliders! Split the brioche slider rolls in half horizontally and place the bottom halves in the baking dish. Drizzle about ¼ cup of melted cowboy butter over the bottoms. Layer the sliced steak, then add slices of a medium jalapeño pepper and 1 cup of shredded sharp cheddar cheese. Finally, distribute the caramelized onions over the top before placing the top halves of the rolls back on. For a finishing touch, brush the remaining ¼ cup of melted cowboy butter over the tops of the rolls.
Bake and Finish with Cowboy Butter
Cover the baking dish with aluminum foil and pop it into the preheated oven. Bake for 15 minutes, letting the cheese melt brilliantly. After that, remove the foil and bake for an additional 3-5 minutes to achieve a beautifully golden brown color on top. Once done, don’t forget to brush any remaining melted cowboy butter over the warm sliders for that extra flavor punch. Slice them up, serve warm, and prepare for some tempting bites that’ll make everyone want seconds!
By following these steps, you'll not only master the art of these Cowboy Butter Steak Sliders but also impress your friends and family with your culinary skills. Enjoy!

Cooking Tips and Notes for Cowboy Butter Steak Sliders
Best Techniques for Caramelizing Onions
Caramelizing onions is an art that can elevate your Cowboy Butter Steak Sliders to new heights. Start with a medium-low heat to prevent burning. Use two tablespoons of butter and let the onions gently sauté for about 25-30 minutes, stirring occasionally. Be patient! The longer you cook, the sweeter and more flavorful they will become. If you find the onions are browning too quickly, reduce the heat and consider adding a splash of water to deglaze the pan.
How to Ensure Your Steak is Juicy and Flavorful
To keep your steak succulent, always remember to season it generously with kosher salt and black pepper. Letting the steak rest for about 30 minutes before cooking allows the flavors to penetrate. When cooking, use high heat briefly to achieve a perfect sear, sealing in those tasty juices. Finally, cover the skillet while cooking to create some steam, helping the steak remain tender. Don’t forget to let it rest a few minutes before slicing—this simple step makes all the difference!
