Ingredients
Method
- Whisk together the soy sauce, Worcestershire sauce, olive oil, lemon juice, brown sugar, minced garlic, smoked paprika, onion powder, black pepper, and kosher salt until the sugar dissolves, about 1 minute.
- Add the sirloin cubes, red bell pepper, green bell pepper, and red onion to a large bag or bowl. Pour the marinade over everything, seal, and refrigerate for 2 to 8 hours.
- Soak wooden skewers in water for 30 minutes if using, then thread the beef and vegetables onto skewers, alternating proteins and vegetables with a small gap between each piece.
- Preheat the grill to 450°F (230°C), oil the grates, and grill the skewers for 10 to 12 minutes, turning every 3 to 4 minutes, until the beef reaches 145°F (63°C) internally.
- Slide the kabobs onto a platter, squeeze fresh lemon over the top, and garnish with fresh parsley before serving.
Notes
The marinade recipe makes enough for up to 2.5 lbs of protein, so you can scale up slightly without adjusting the quantities. If you're making this for a crowd, mix a double batch of marinade and use two separate bags so everything gets coated properly. The brown sugar is the part most likely to burn over high heat, so keep the grill lid open and watch the skewers during the last few minutes.
