Preparation
Marinate the steak: In a bowl, mix melted butter, lime juice, lime zest, garlic, chopped cilantro, cumin, salt, and pepper. Rub the marinade into the steak and refrigerate for at least 30 minutes (up to 4 hours for more flavor).
Make the creamy lime sauce: In a small bowl, whisk together sour cream, avocado mayo, lime juice, zest, cilantro, garlic powder, salt, and pepper. Chill until ready to serve.
Grill or sear the steak: Preheat a grill or skillet over medium-high heat. Remove steak from the marinade and pat dry. Grill or sear the steak for 3–4 minutes per side, or until it reaches your preferred doneness (135°F/57°C for medium-rare). Let rest for 5 minutes, then slice against the grain.
Serve: Plate the sliced steak and drizzle or serve with the creamy lime sauce on the side. Garnish with extra cilantro and lime wedges if desired.
