01 - Toss steak cubes with olive oil, salt, black pepper, smoked paprika, and dried thyme in a large bowl. Allow to marinate at room temperature for a minimum of 15 minutes.
02 - Preheat grill or grill pan to medium-high heat. Soak wooden skewers in water for 20 minutes if using to prevent burning.
03 - Thread marinated steak cubes onto skewers, spacing pieces to ensure even cooking.
04 - Grill skewers for 2 to 3 minutes per side, turning once, until steak reaches desired doneness and is browned.
05 - Melt butter in a small saucepan over medium heat. Add minced garlic and sauté for 1 to 2 minutes until fragrant. Remove from heat and stir in parsley, lemon zest, and lemon juice.
06 - Brush hot garlic butter over grilled steak skewers immediately. Garnish with extra parsley and lemon wedges as desired.
