Keto Steak Kebabs

Kebabs are a summer grilling staple, but grill-pans (and broilers!) make them awesome year-round. Plus, they’re festive to serve, quick to cook, and easy to eat. For this kebab recipe, a rich, savory low-carb marinade tenderizes the sirloin and becomes a delicious glaze as it cooks. You can change up your kebabs by swapping in cherry or grape tomatoes or cubed eggplant for some of the other veggies, make sure to recalculate the macros if you do. By the way, if some pieces of the sirloin have thin or flat edges you can double them over when threading them on the skewers; this helps ensure the meat pieces are similar size and thickness so they cook evenly.

  • In a medium bowl, combine the olive oil, tamari sauce, Worcestershire sauce, red wine vinegar, Dijon mustard, garlic powder, sweetener, Italian herb blend, salt, and pepper and whisk together.
  • Place the steak and vegetables into a large plastic zip-top bag, then add the the marinade to the meat and vegetables. Seal the bag, then gently massage its contents to coat the meat with the marinade. Refrigerate for at least 1 hour, up to 6 hours.
  • Meanwhile, if you’re using wooden skewers, soak them in water.
  • Preheat your grill on high. Thread the kebabs: thread alternating pieces of marinated meat and vegetables until the skewers are filled, aiming for an even distribution on each skewer.
  • Place the kebabs on the grill directly over the heat and reduce heat to medium-high. Grill, flipping each kebab every 2 to 3 minutes, until the meat is cooked medium-rare to medium and the vegetables start to char just around the edges, 9 to 12 minutes total. Serve right away.
