Ingredients You’ll Need

• 800g beef sirloin or rump steak, cut into 3cm cubes
• 2 large red bell peppers, deseeded and cut into 3cm pieces
• 2 large yellow bell peppers, deseeded and cut into 3cm pieces
• 2 large red onions, cut into wedges and separated into layers
• 4 tablespoons olive oil
• 3 tablespoons plain yoghurt
• 2 tablespoons lemon juice
• 4 cloves garlic, minced
• 1 tablespoon ground cumin
• 1 tablespoon smoked paprika
• 1 teaspoon ground coriander
• 1 teaspoon black pepper
• 1½ teaspoons sea salt
• Wooden or metal skewers (if using wooden, soak in water for 30 minutes)

Tip: Choose beef that has a good amount of marbling — those thin streaks of fat running through the meat. This fat renders during cooking, basting the meat from the inside and ensuring the kebabs stay wonderfully moist.

How to Make Grilled Beef Kebabs with Peppers and Onions

1. Prepare the marinade: In a large bowl, whisk together the olive oil, yoghurt, lemon juice, minced garlic, cumin, smoked paprika, coriander, black pepper, and salt. The mixture should be a rich, brick-red colour with a sharp, tangy aroma from the yoghurt and lemon.
2. Marinate the beef: Add the cubed beef to the bowl and use your hands to toss everything together, ensuring every piece of meat is thoroughly coated. You want the marinade to cling to every surface. Cover the bowl with cling film and refrigerate for at least 2 hours, or up to 8 hours for a deeper flavour. The beef will darken slightly as it marinates.
3. Prepare the vegetables: While the beef marinates, prepare your peppers and onions. The pieces should be roughly the same size as the beef cubes — this ensures even cooking. Toss them in a separate bowl with a tablespoon of olive oil and a pinch of salt. They should be glossy and lightly seasoned.
4. Assemble the skewers: Thread the marinated beef, peppers, and onions onto the skewers, alternating the ingredients. Don’t pack them too tightly — leave a tiny gap between each piece so the hot air can circulate and char the surfaces evenly. You should get about 6–8 skewers depending on their length.
5. Preheat the grill: Heat your grill or grill pan to a medium-high heat — around 200°C. You want it hot enough to sear the meat, but not so hot that the outside burns before the inside is cooked. The grill bars should be visibly hot and shimmering.
6. Grill the kebabs: Place the skewers on the hot grill. You should hear a satisfying sizzle immediately. Cook for 4 minutes, then use tongs to turn them. Look for deep brown char marks on the underside — that’s the flavour. Cook for another 4 minutes, then turn again. For medium-rare beef, the internal temperature should reach 52°C – 54°C when checked with a meat thermometer. For medium, aim for 57°C – 60°C. The total cooking time will be 12–14 minutes. The aroma at this stage is incredible — smoky, earthy, and slightly sweet from the charring peppers.
7. Rest before serving: Remove the skewers from the grill and place them on a warm plate. Loosely tent with foil and let them rest for 5 minutes. This is a crucial step — it allows the juices to redistribute throughout the meat. The beef will look glossy and the vegetables will be beautifully softened with charred edges.

Tips From My Kitchen

• Don’t skip the yoghurt in the marinade: Yoghurt contains lactic acid, which gently tenderises the beef without making it mushy. It also helps the spices cling to the meat and promotes a beautiful, caramelised crust on the grill.
• Soak wooden skewers thoroughly: If you’re using wooden skewers, soak them in cold water for at least 30 minutes. I used to struggle with this dish until I discovered this technique — it stops the skewers from catching fire on the grill and keeps the kebabs stable.
• Cut ingredients to a uniform size: Take the time to cut your beef, peppers, and onions into roughly 3cm pieces. If some pieces are much smaller, they’ll cook faster and might burn before the larger pieces are done. Uniformity is the secret to even cooking.
• Let the grill get properly hot: A hot grill is non-negotiable. If you place the kebabs on a grill that isn’t hot enough, the meat will stick and start to steam rather than sear. You need that initial high heat to lock in the juices and create those desirable char marks.
• Keep a little space on the skewers: As mentioned, don’t cram the ingredients together. A small gap between each piece allows heat to circulate, ensuring the vegetables soften and the beef gets a good sear all the way around.

Equipment You’ll Need

• Grill or grill pan
• Meat thermometer
• Tongs
• Basting brush

Common Mistakes to Avoid

• Overcrowding the pan: If you’re using a grill pan indoors, don’t try to cook all the skewers at once if they don’t fit comfortably. Overcrowding traps steam, which prevents the meat from getting a good sear and leaves it grey rather than beautifully charred. Cook in batches if necessary, and keep the finished skewers warm in a low oven.
• Wrong temperature: A grill that’s too cool will cause the meat to stick and dry out before it develops any colour. A grill that’s too hot will burn the outside while leaving the inside raw. Stick to a medium-high heat (around 200°C) and always use a meat thermometer to check doneness rather than guessing.
• Skipping the rest time: After all that careful cooking, it’s tempting to dive straight in. But resting the skewers for 5 minutes is essential. Without this rest, the juices will run out onto the plate as soon as you cut into the meat, leaving the beef dry and less flavourful. Patience here pays off.

Delicious Variations to Try

• Spicy Version: Add 1–2 finely chopped red chillies to the marinade, or stir in a teaspoon of chilli flakes. For an extra kick, sprinkle a little cayenne pepper over the assembled skewers just before grilling.
• Vegetarian/Vegan Option: Replace the beef with large chunks of halloumi (for a vegetarian version) or firm tofu that has been pressed and marinated. Use the same marinade and follow the same grilling instructions — halloumi will need slightly less time, about 6–8 minutes total.
• Different Protein: This recipe works beautifully with chicken thigh fillets (cut into cubes) or lamb leg steaks. Adjust the cooking time accordingly — chicken needs to reach an internal temperature of 74°C, while lamb can be cooked to medium-rare at 54°C, similar to beef.

What to Serve With Grilled Beef Kebabs with Peppers and Onions

• Fluffy basmati rice or warm flatbreads to soak up the juices
• A crisp green salad with a lemony dressing
• A dollop of yoghurt mixed with chopped mint and a pinch of salt
• Grilled courgettes or aubergine for extra vegetables
• If you’re planning a bigger spread, this pairs wonderfully with the Cheesy Halal Chicken Enchilada Casserole for a truly indulgent meal.
