Creating delicious Cowboy Butter Steak Sliders is easy when you follow these simple steps:

1. Prepare the Cowboy Butter: In a bowl, mix softened butter, minced garlic, parsley, chives, smoked paprika, Worcestershire sauce, and lemon juice. Combine well and set aside.
2. Season the Steak: Rub olive oil on the flank steak and season it generously with salt and pepper on both sides.
3. Grill the Steak: Heat your grill over medium-high heat. Grill the steak for about 4-5 minutes per side, or until it reaches your desired level of doneness. Use a meat thermometer for accuracy (135°F for medium-rare).
4. Rest the Steak: Once cooked, remove the steak from the grill and let it rest for 5-10 minutes. This helps retain juices.
5. Slice the Steak: After resting, slice the steak against the grain into thin strips.
6. Toast the Buns: Lightly toast the slider buns on the grill or in a skillet for a few minutes until golden brown.
7. Assemble the Sliders: Spread a generous amount of cowboy butter on each bun. Place sliced steak on the bottom half of the bun and add any optional toppings such as jalapeños or arugula.
8. Top and Serve: Place the top half of the bun on the steak. Secure with a toothpick if desired.
9. Repeat: Continue assembling the rest of the sliders until all ingredients are used.
10. Serve Warm: Serve the sliders warm for the best flavor experience.

By following these straightforward steps, you will have crafted mouthwatering Cowboy Butter Steak Sliders in no time!
