Best Cut of Beef for Kabobs
Sirloin is a great choice for kabobs: flavorful, fairly lean, and budget-friendly. I cut a thick sirloin into roughly 1 1/2-inch pieces so the meat and vegetables cook evenly. Other tender cuts, such as filet mignon or strip steak, also work well if you prefer them.
Choose a thicker cut rather than thin slices so the steak and vegetables finish at similar times and you avoid overcooking the meat.
Marinating Time
Marinate based on your schedule. Fifteen minutes helps, but one to two hours is ideal for deeper flavor. This marinade is versatile and works well on other grilled proteins too.
Recipe Ingredients
For the Steak and Marinade

- Steak: 2 lb sirloin, cut into 1 1/2-inch pieces.
- Garlic: 2 cloves, minced.
- Olive oil: 3 tablespoons.
- Worcestershire sauce: 3 tablespoons.
- Balsamic vinegar: 2 tablespoons.
- Crushed red pepper: 1/2 teaspoon.
- Sea salt and cracked pepper: 1/2 teaspoon each, or to taste.
- Vegetables: 2 small zucchini, sliced 1/2-inch thick; 1 red onion, cut into 1-inch pieces.
For the Cilantro Chimichurri

- Cilantro: 1 cup, chopped (use fresh).
- Red pepper flakes: 1/4 teaspoon, adjust to taste.
- Olive oil: 1/3 cup.
- Red wine vinegar: 2 tablespoons.
- Lemon juice: 1/2 lemon, juiced.
- Oregano: 1 teaspoon dried or 1 tablespoon fresh.
- Garlic: 2 cloves, minced.
- Salt and pepper: 1/4 teaspoon each, or to taste.
Recipe Tips
- Don’t overcrowd the skewers. Leave small gaps so heat circulates and everything cooks evenly.
- Turn the kabobs regularly—rotate every 2–3 minutes—to avoid overcooking the steak.
- The chimichurri can be made two ways: pulse in a food processor for a smoother, slightly creamier sauce, or finely chop the cilantro and whisk ingredients together for a more traditional, oil-based chimichurri.
- I don’t marinate the vegetables; a light toss with olive oil, garlic powder, salt, and pepper keeps them crisp and nicely charred. If you prefer, you can add some marinade to them.

Kabobs and Marinade:
- 2 lb steak (sirloin), cut in 1 1/2 in. pieces
- 2 garlic cloves, minced
- 3 T olive oil
- 3 T Worcestershire sauce
- 2 T balsamic vinegar
- 1/2 tsp crushed red pepper
- 1/2 tsp fresh cracked pepper
- 1/2 tsp sea salt

Chimichurri
- 1 cup chopped cilantro
- 1/4 tsp red pepper flakes

- 1/4 tsp pepper
- 1/4 tsp salt

Instructions
- Whisk the marinade ingredients (olive oil, balsamic, Worcestershire, minced garlic, red pepper, sea salt, cracked pepper). Toss with the steak pieces and refrigerate in a bowl or zip-top bag for 15 minutes to several hours.
- Preheat the grill to medium-high heat when the meat has marinated.
- Thread the steak and vegetables onto skewers, leaving small gaps so they cook evenly. Grill the skewers, turning every 2–3 minutes, until the steak reaches desired doneness—about 10–12 minutes total depending on heat and thickness.
