Ingredients:
- 1 1/2 pounds boneless steak such as ribeye (filet, sirloin)
- Neutral oil (as needed)
- Kosher salt (to taste)
- Freshly cracked black pepper (to taste)
- 3 sweet onions (thinly sliced)
- 9 slider buns
- 3/4 pound sliced havarti cheese
- 1 stick unsalted butter (at room temperature)
- 4 garlic cloves (minced)
- 1/2 lemon (zested and juiced)
- 1 tablespoon dijon mustard
- 1 teaspoon paprika
- 1/2 teaspoon cayenne
- 1/2 teaspoon dried thyme
- 1 teaspoon red pepper flakes
Cooking Instructions
Let’s get started on these incredible sliders! The process is broken down into a few key phases, ensuring each component shines.
Phase 1: Preparing the Steak and Onions
First, we need to get our steak ready for searing. Pat the steak dry with paper towels. This is a crucial step for achieving a beautiful crust. Season generously on all sides with kosher salt and freshly cracked black pepper. Don’t be shy with the seasoning; it really makes a difference in the final flavor.
While the steak rests, let’s tackle the onions. Heat a tablespoon of neutral oil in a large skillet or cast-iron pan over medium heat. Add the thinly sliced sweet onions and a pinch of salt. We want to caramelize these onions slowly, drawing out their natural sweetness. This will take about 20-30 minutes, stirring occasionally. They should become soft, golden brown, and wonderfully jammy. Once they’re done, remove them from the pan and set them aside. You can add them back to the pan later if you want to keep them warm.
Now, back to the steak. Wipe out the skillet you used for the onions, or grab a fresh one. Add enough neutral oil to coat the bottom of the pan and heat it over medium-high heat until it’s shimmering and just starting to smoke. Carefully place the seasoned steak in the hot pan. Sear for about 3-5 minutes per side for medium-rare, depending on the thickness of your steak. You’re looking for a deep, golden-brown crust. Once seared, remove the steak from the pan and let it rest on a cutting board for at least 10 minutes. This resting period is essential for the juices to redistribute throughout the meat, ensuring a tender and moist steak.
Phase 2: Crafting the Cowboy Butter
This is where the magic truly happens! In a medium bowl, combine the softened unsalted butter, minced garlic, lemon zest, lemon juice, Dijon mustard, paprika, cayenne pepper, dried thyme, and red pepper flakes. Mix everything together until it’s well combined and forms a cohesive butter. You can taste it and adjust seasonings if you like – maybe a touch more lemon or a pinch more cayenne for extra heat. This cowboy butter is incredibly versatile and delicious on its own, but it’s the perfect complement to our steak. You can make this butter ahead of time and keep it in the refrigerator; just let it soften slightly before using.
Phase 3: Assembling the Sliders
Once your steak has rested, it’s time to slice it thinly against the grain. This ensures the steak is easy to chew and incredibly tender.
Lightly toast your slider buns. You can do this in the skillet you used for the steak (add a touch more butter or oil if needed) or in a toaster. A lightly toasted bun adds a nice textural contrast.
Now, let’s build these sliders! On the bottom half of each slider bun, layer a generous portion of the thinly sliced steak. Top the steak with a good amount of the caramelized onions. Next, place a slice of havarti cheese over the onions. If your steak and onions are still warm, the cheese will start to melt. For an extra cheesy melt, you can pop the assembled sliders under the broiler for a minute or two, watching them very carefully to prevent burning.
Finally, spread a generous dollop of your prepared cowboy butter on the top half of each slider bun. Place the top bun on each slider.
Serve these Cowboy Butter Steak Sliders immediately and watch them disappear! They are a fantastic way to enjoy the bold flavors of steak in a fun and convenient slider format. Enjoy every delicious bite!

Frequently Asked Questions:
Can I make the cowboy butter ahead of time?

Soft slider buns, brioche rolls, or even small Hawaiian sweet rolls are perfect choices. They offer a delicate texture that complements the rich steak and butter without overpowering it.

The standard cowboy butter recipe isn’t inherently spicy, but you can easily add a pinch of cayenne pepper or finely diced jalapeño to the butter mixture if you prefer a little heat. Adjust to your personal preference!
