🛒 Ingredients

For the Beef & Vegetables

• 1½ lb (680 g) beef sirloin or tenderloin, cut into 1–1½-inch cubes
• 1 medium bell pepper, cut into chunks
• 1 small zucchini, sliced into thick rounds
• ½ medium red onion, cut into chunks
• 8–10 cherry tomatoes, optional
• Wooden or metal skewers

For the Keto Marinade

• 3 tbsp olive oil
• 2 tbsp soy sauce or coconut aminos
• 1 tbsp lemon juice
• 1 tbsp Worcestershire sauce
• 2 cloves garlic, minced
• 1 tsp smoked paprika
• 1 tsp Italian seasoning
• ½ tsp onion powder
• ½ tsp black pepper
• ¼ tsp salt, or to taste
• ¼ tsp red pepper flakes, optional

👩‍🍳 Instructions

1. Prepare the beef:
   Pat the beef cubes dry with paper towels and place them in a large bowl.
2. Make the marinade:
   Whisk together olive oil, soy sauce, lemon juice, Worcestershire sauce, garlic, smoked paprika, Italian seasoning, onion powder, black pepper, salt, and red pepper flakes.
3. Marinate:
   Pour the marinade over the beef and toss well to coat. Cover and refrigerate for at least 30 minutes, or up to 2 hours for more flavor.
4. Prepare the vegetables:
   Cut the peppers, zucchini, and onion into pieces similar in size to the beef.
5. Assemble the kabobs:
   Thread the beef and vegetables onto skewers, alternating between the ingredients.
6. Grill:
   Preheat the grill to medium-high heat. Lightly oil the grates. Grill the kabobs for about 3–4 minutes per side, turning regularly, until the beef reaches your preferred doneness.
7. Oven method:
   Preheat the oven to 425°F (220°C). Place the kabobs on a foil-lined baking sheet or wire rack. Bake for about 12–15 minutes, turning halfway through. For extra browning, broil for 1–2 minutes at the end while watching closely.
8. Rest & serve:
   Let the kabobs rest for 5 minutes before serving. Spoon any remaining cooked juices over the top.

💡 Keto Tips

• Use sirloin, ribeye, or tenderloin for tender kabobs.
• Keep vegetables keto-friendly such as zucchini, bell pepper, mushrooms, and onion in moderate amounts.
• For a creamy dipping sauce, serve with garlic Greek yogurt sauce or keto ranch.
• Avoid sweet BBQ sauces or sugary marinades to keep the recipe low-carb.

🔥 Tip: Don’t overcook the beef—kabobs cook quickly, and removing them from the heat when just done helps keep them juicy.
