Ingredient breakdown: key components
- Bell peppers: I love the sweet, smoky aroma they develop—slice them thick so they don’t burn too quickly, and toss in a little olive oil before skewering.
- Zucchini: Its tender, almost creamy texture when grilled makes it a star—cut into even chunks to prevent uneven cooking; a sprinkle of salt enhances that juicy bite.
- Red onion: The way they caramelize and turn ruby-red with a hint of char gets me every time—soak in a bit of lemon juice beforehand to tame the sharpness.
- Cherry tomatoes: Oozy and bursting with juice, they add a smoky pop—use the smallest ones to avoid sogginess, and skewer tightly for even cooking.
- Marinade: A quick mix of olive oil, smoked paprika, garlic, and lemon—brightens the veggies and imparts that smoky depth I crave; don’t skip the lemon zest for extra zing.
- Skewers: Metal or soaked wooden ones—metal heats evenly and crisps the veggies beautifully, while soaked wood prevents burning and adds a subtle smoky note.

Step-by-step guide to vegetable kababs
- Gather your vegetables: bell peppers, zucchini, red onion, cherry tomatoes. Cut bell peppers and zucchini into 2-inch chunks; slice onion into thick rings. Soak wooden skewers in water for 30 minutes to prevent burning.
- Prepare the marinade: in a bowl, whisk together 3 tbsp olive oil, 1 tsp smoked paprika, 2 minced garlic cloves, and the zest of 1 lemon. Toss the vegetables gently in the marinade, ensuring even coating. Let sit for 15-20 minutes while you preheat the grill.
- Preheat your grill to medium-high, about 200°C (390°F). Clean the grates well and oil lightly to prevent sticking.
- Thread the vegetables onto skewers, alternating colors and types for visual appeal. Leave a little space between pieces for heat circulation.
- Place the skewers on the grill. Cook for about 8-10 minutes total, turning every 2-3 minutes. Look for a slight char, fragrant smoky aroma, and vegetables that are tender but still crisp.
- Check for doneness: veggies should have deep grill marks, with some caramelization on the edges, and be easily pierced with a fork. The tomatoes should be soft and bursting, onions caramelized.
- Remove from grill and let rest for 2-3 minutes on a plate. Brush lightly with extra lemon juice if desired for brightness. Serve hot or at room temperature.
Let the kababs rest for a couple of minutes off heat, allowing flavors to settle. Serve immediately, paired with a fresh squeeze of lemon or your favorite dip for added brightness.

Preparation, storage, and reheating tips
- Prep vegetables: Cut bell peppers, zucchini, and onions into chunks a day ahead. Store in airtight containers in the fridge; they stay fresh for up to 24 hours and retain their vibrant color and crispness.
- Marinate early: Mix marinade ingredients and toss with vegetables at least 2 hours beforehand. Keep covered in the fridge; flavors deepen and vegetables absorb the smoky notes during this time.
- Skewer in advance: Thread vegetables onto skewers up to 4 hours before grilling. Keep covered in the fridge; this helps flavors meld and makes grilling quicker when ready to cook.
- Refrigerate cooked kababs: If making ahead, store grilled kababs in an airtight container for up to 1 day. Reheat on a grill or in a hot pan until warmed through—look for a slight shimmer and aroma of smoky spices to tell you they’re ready.
- Reheat with care: For best texture, reheat in a hot skillet or on the grill for 2–3 minutes, turning occasionally. The vegetables should be hot, slightly crispy on the edges, and fragrant with smoky spice.
