Do I need to marinate the steak before grilling?
No marinating is required—the steak seasoning and chimichurri provide plenty of flavor. However, you can marinate the cubed steak in olive oil and seasonings for 2–4 hours for extra tenderness.
What's the best doneness for steak kabobs?
Medium-rare (130–135°F internal temp) keeps the beef juicy. Grill 2–3 minutes per side for 1-inch cubes over medium-high heat, turning every 90 seconds for even cooking.
Can I make chimichurri ahead of time?
Yes. Chimichurri keeps in an airtight container in the fridge for up to 5 days. Make it 1–2 hours before serving so flavors meld.
What can I use instead of sirloin steak?
Ribeye, New York strip, or filet mignon all work well. Avoid very lean cuts like tenderloin, which can dry out quickly on the grill.
Do I need wooden or metal skewers?
Either works. Soak wooden skewers in water for 30 minutes before grilling to prevent charring. Metal skewers require no prep and conduct heat for even cooking.
