🧾 Ingredients (Serves 4–6)
For the Steak:
- 1½ lbs (680 g) sirloin, ribeye, or New York strip steak
- Salt and freshly cracked black pepper, to taste
- 1 tablespoon olive oil or neutral cooking oil
For the Cowboy Butter:
- ½ cup (1 stick) unsalted butter
- 3 garlic cloves, minced
- 1 tablespoon Dijon mustard
- 1 tablespoon lemon juice
- 1 tablespoon Worcestershire sauce
- ½ teaspoon crushed red pepper flakes
- 1 teaspoon smoked paprika
- 1 tablespoon fresh chopped parsley
- ½ teaspoon dried thyme or rosemary (optional)
- Salt & pepper to taste
For the Sliders:
- 12 slider buns or Hawaiian rolls
- 6 slices provolone, mozzarella, or cheddar cheese (halved)
- Optional: pickled onions, arugula, caramelized onions, or horseradish mayo
👩🍳 Instructions
- Prepare the steak:
Pat steak dry and season generously with salt and pepper. Cut into small bite-sized pieces or strips for easy serving on sliders. - Sear the steak:
Heat oil in a large skillet over high heat. Add steak in a single layer and sear 2–3 minutes per side until browned and medium-rare to medium. Transfer to a plate and tent with foil. - Make the cowboy butter:
In a saucepan, melt butter over medium heat. Add garlic and cook for 30 seconds. Stir in mustard, lemon juice, Worcestershire, pepper flakes, paprika, herbs, salt, and pepper. Simmer 1–2 minutes, then remove from heat. - Toss the steak in cowboy butter:
Pour most of the cowboy butter over the cooked steak and toss to coat. - Assemble the sliders:
Slice buns, place a spoonful of steak on each bottom half, top with cheese, and any extras (like arugula or onions). Add the top bun. - Bake to melt the cheese (optional):
Place sliders in a baking dish, cover loosely with foil, and bake at 350°F (175°C) for 8–10 minutes, or until cheese is melty. - Brush with remaining cowboy butter:
Before serving, brush the tops of the buns with remaining butter for an extra pop of flavor.
💡 Tips
- Use thinly sliced steak or even leftover grilled steak to speed things up.
- Don’t overcook the steak—it’s best when tender and juicy.
- Cowboy butter can be made in advance and stored in the fridge for 5–7 days.
- Slice buns carefully to avoid tearing—especially soft Hawaiian rolls.
🔁 Variations & Substitutions
- Swap steak with chicken, pulled pork, or even portobello mushrooms.
- Add a kick of heat with jalapeños or pepper jack cheese.
- Serve open-faced on Texas toast or thick-cut baguette slices.
- Make mini versions using King’s Hawaiian rolls sliced as one large batch and baked pull-apart style.
❓ FAQs
What is cowboy butter?
Cowboy butter is a compound butter made with garlic, herbs, lemon, and spices—rich, zesty, and full of flavor.
Can I grill the steak instead of pan-searing?
Yes! Grilling adds a smoky layer of flavor that’s amazing for sliders.
Can I make this ahead?
You can cook the steak and butter in advance, then reheat gently and assemble just before serving.
Can I freeze these?
They’re best fresh, but the steak and cowboy butter freeze well separately.
