Ingredients and Preparation

Key Ingredients and Their Roles

• Steak – Choose a tender cut like filet mignon, ribeye, or NY strip for the best flavor and texture.
• Havarti Cheese – A creamy, mild cheese that melts beautifully. Alternatives: Fontina, provolone, or Swiss.
• Slider Rolls – Soft, slightly sweet rolls like King’s Hawaiian work best. Regular dinner rolls or brioche buns also work.
• Butter – The base of the cowboy butter, adding richness and flavor.
• Garlic & Herbs – Fresh parsley, chives, and thyme provide aromatic depth.
• Lemon Zest & Juice – Adds brightness to balance the richness of the butter.
• Spices (Cayenne, Paprika, Red Pepper Flakes) – These bring just a touch of heat for a well-rounded flavor.
• Caramelized Onions – Add sweetness and depth to complement the savory steak.

Ingredient Substitutions

• No steak? Try chicken breast, portobello mushrooms (for a vegetarian option), or even grilled tofu.
• Dairy-free? Swap the butter for plant-based butter and use dairy-free cheese.
• Want extra spice? Add a dash of hot sauce to the cowboy butter for more heat.

Step-by-Step Instructions

Step 1: Prepare the Steak

Trim any excess fat and silver skin from the steak. Rub it with a little oil, then season generously with kosher salt and freshly cracked black pepper. If your steak is thick, season a bit more heavily. Wrap in plastic wrap and refrigerate for a couple of hours to enhance flavor.

Step 2: Make the Cowboy Butter

In a small saucepan over low heat, melt the butter while whisking constantly. Stir in lemon juice and zest, minced garlic, Dijon mustard, and dry seasonings. Remove from heat and fold in the chives and fresh parsley. Season with salt and pepper to taste. Set aside a few tablespoons for basting the steak, and reserve the rest for the buns.

Step 3: Cook the Steak

Remove the steak from the fridge and let it rest at room temperature for about 30 minutes. Preheat your grill (or cast iron skillet) to medium-high heat. Cook the steak for about 2-3 minutes per side over direct heat, brushing with cowboy butter as it cooks. If flare-ups happen, move the steak to an indirect heat zone. Cook until your desired doneness is reached, then remove the steak from heat and let it rest under tented foil for 10 minutes before slicing.

Step 4: Caramelize the Onions

While the steak rests, heat a cast iron skillet over medium heat. Add a few tablespoons of butter and toss in the sliced onions. Stir occasionally, letting them cook down until golden brown and caramelized, about 15 minutes.

Step 5: Assemble the Sliders

Preheat the oven to broil and line a baking sheet with parchment paper. Slice the slider buns in half and brush the insides with the remaining cowboy butter. Place a slice of havarti cheese on both the top and bottom buns. Layer the caramelized onions on the bottom buns, followed by sliced steak. Broil for 1-2 minutes until the cheese melts. Place the top buns over the steak, press gently, and serve.

Beginner Tips and Notes

• How to Tell If Your Steak is Done: Use a meat thermometer—125°F for rare, 135°F for medium-rare, 145°F for medium, and 160°F for well-done.
• Avoid Overcooking: If using a grill, keep an eye on flare-ups and move the steak to indirect heat when necessary.
• Make It Ahead: The cowboy butter can be made in advance and stored in the fridge for up to a week. Let it come to room temperature before using.
• Want Extra Juiciness? Let the steak rest before slicing—this keeps the juices inside.

Serving Suggestions

• Pair With: A simple arugula salad, crispy sweet potato fries, or classic coleslaw for a balanced meal.
• Dipping Sauce Idea: Serve with extra cowboy butter on the side for dipping.
• Beverage Pairing: Try these sliders with a cold beer, lemonade, or even a bold red wine like Cabernet Sauvignon.
• Leftover Storage: Store leftover sliders in an airtight container in the fridge for up to 3 days. Reheat in an oven at 300°F for 5-7 minutes.
