Notes
Here's my tips on How To Cook Perfect Steak Kabobs:- buy a great cut of meat. When you serve steak kabob style you don't need as much meat per person so I like to splurge on a better quality steak. I buy the Prime Sirloin or Tenderloin Steaks at Costco which are tender and lean, and a better price than at the grocery store. Since your guests will be eating kabobs without a knife and fork, you don't want stringy, tough to chew meat.- don't over cook it. You bought a great cut of meat, so serve it medium rare to medium. Kabobs cook quickly so don't wander off and get distracted.- have your grill piping hot. You want a nice char on the kabobs. It's the caramelization on the steak that adds that great barbecue flavor. Be sure and start with a clean grill. If you started with a hot grill, you'll know it's time to turn the kabobs when they release easily from the grill.- cut even size pieces so the kabobs cook at the same rate. Don't add vegetables to your steak kabobs. If you want grilled vegetables, make a separate veggie kabob.- season the steak kabobs well on all sides. If may seem like you're adding too much seasoning but you'll lose some on the grill and this is your only seasoning. I like to use lemon pepper, but if you don't have that use salt and lots of freshly ground black pepper. A simple seasoning really lets the flavor of your great steak shine.
