→ Slider Assembly

18 - 8 slider buns
19 - 1 cup arugula or baby spinach
20 - 1 small red onion, thinly sliced
21 - 1-2 tbsp olive oil for toasting buns

# How-to Steps:

01 - Rub the steak thoroughly with olive oil, kosher salt, and black pepper. Allow the meat to rest at room temperature for 15 minutes to ensure even cooking.
02 - In a mixing bowl, combine softened butter, minced garlic, lemon juice and zest, Dijon mustard, Worcestershire sauce, smoked paprika, cayenne pepper, chopped parsley, chives, dill, red pepper flakes, and salt. Mix until completely smooth and uniform. Set aside at room temperature for spreading.
03 - Heat a grill pan or cast-iron skillet over high heat until smoking hot. Sear the steak for 3 to 4 minutes per side for medium-rare doneness, adjusting time for preferred doneness. Remove from heat and let rest for 5 minutes before slicing thinly against the grain.
04 - Lightly brush the cut sides of slider buns with olive oil. Place in a warm skillet for 1 to 2 minutes until golden brown and crisp.
05 - Generously spread cowboy butter on both halves of each toasted bun. Layer the bottom buns with arugula, sliced steak, and red onion rings. Crown with the bun tops and press gently to adhere.
06 - Arrange sliders on a platter and serve immediately while warm. Cowboy butter can be passed separately for additional serving.
