Chicken and Sweet Potato Traybake

The smell hit me first: smoky, sharp, and alive with heat. I'd tossed chicken thighs in piri-piri paste without much thought, scattered sweet potatoes around them, and shoved the whole tray into the oven. Forty minutes later, I had a dinner that looked like I'd planned it, tasted like I'd labored over it, and required exactly one pan to clean. That night, I learned that the best recipes aren't always the ones with the longest ingredient lists.

I made this on a Tuesday when I was too tired to think. My flatmate wandered into the kitchen, drawn by the smell, and ended up setting the table without being asked. We ate straight from the tray, squeezing lemon over everything and fighting over the crispy bits of sweet potato. It became our midweek ritual after that, the kind of meal that turns an ordinary evening into something you look forward to.

Ingredients

• Bone-in, skin-on chicken thighs: The skin crisps up beautifully in the oven and the bone keeps the meat moist, so don't be tempted to swap for breasts unless you want dry, sad chicken.
• Piri-piri seasoning: This is where the flavor lives; I use paste when I want it richer and powder when I'm feeling lazy, both work perfectly.
• Sweet potatoes: Cut them into equal chunks or they'll cook unevenly, with some pieces turning to mush while others stay hard.
• Red onion: Thick wedges hold their shape and caramelize at the edges, adding sweetness that balances the heat.
• Bell peppers: Use one red and one yellow for color, but honestly any combination works as long as they're chunky enough not to collapse.
• Cherry tomatoes: Add these halfway through so they burst and release their juices without turning to paste.
• Garlic: Sliced thin, it turns golden and sweet instead of burning, which is what happens when you mince it for roasting.
• Smoked paprika: A teaspoon deepens the smokiness without overpowering the piri-piri.
• Olive oil: Just enough to coat the vegetables and help the chicken skin crisp up.
• Fresh coriander or parsley: A handful of green at the end makes everything look intentional.
• Lemon wedges: Squeeze them over just before eating; the acid cuts through the richness and wakes up every flavor.

Instructions

Preheat and prep:

Get your oven to 200°C (180°C fan) so it's properly hot when the tray goes in. This ensures the chicken skin starts crisping immediately instead of steaming.

Coat the chicken:

In a large bowl, rub the chicken thighs all over with piri-piri seasoning, olive oil, smoked paprika, salt, and pepper until every inch is covered. The skin should look glossy and dark red.

Arrange the vegetables:

Spread the sweet potatoes, onion wedges, and both peppers across a large baking tray, then drizzle with olive oil and scatter the garlic slices over the top. Toss everything with your hands so it's lightly coated, then spread it out in a single layer so it roasts instead of steams.

Nestle the chicken:

Tuck the seasoned chicken thighs among the vegetables, skin-side up, making sure they're not crowded. The skin needs space to crisp.

First roast:

Slide the tray into the oven and roast for 30 minutes without opening the door. The kitchen will start to smell incredible around the 20-minute mark.

Add the tomatoes:

Scatter the halved cherry tomatoes over the tray and return it to the oven for another 10 minutes. The tomatoes will soften and release their juices, creating a light sauce at the bottom of the tray.

Finish and serve:

Pull the tray out when the chicken juices run clear and the vegetables are golden at the edges. Scatter fresh coriander or parsley over the top and serve with lemon wedges on the side.

One night, I added a handful of chili flakes because I wanted to impress someone who claimed they loved spicy food. They spent the entire meal fanning their mouth and laughing, and we've been together three years now. This traybake has been there for lazy Sundays, rushed weeknights, and dinners where I wanted to look like I tried without actually trying. It never lets me down.

Making It Your Own

I've swapped sweet potatoes for butternut squash when that's what I had, and once I used a mix of parsnips and carrots because my flatmate was on a no-nightshade kick. The method stays the same: chunky vegetables, bold seasoning, hot oven. If you want more heat, toss in fresh chili slices with the garlic or use extra piri-piri paste. If you want it milder, cut the seasoning in half and add a drizzle of honey before roasting.

What to Serve Alongside

This is a complete meal on its own, but sometimes I'll throw together a quick green salad with lemon juice and olive oil to cut through the richness. Steamed green beans work too, or a bowl of couscous if you want to stretch the servings. A chilled Sauvignon Blanc is my go-to drink, though a light lager works just as well if you're not in a wine mood.

Storage and Reheating

Leftovers keep in the fridge for up to three days in an airtight container. I reheat them in a hot oven for 10 minutes to crisp the chicken skin back up, though the microwave works if you're in a hurry and don't mind softer skin. The flavors deepen overnight, so day-two lunch is often better than the original dinner.

• Store the chicken and vegetables together so the juices keep everything moist.
• Reheat at 180°C for the best texture, or use the microwave on medium power for 2 minutes if you're short on time.
• Don't freeze this; the sweet potatoes turn grainy and the peppers go watery when thawed.

Recipe FAQ

→ Can I use chicken breasts instead of thighs?

Yes, you can use boneless chicken breasts, but reduce the cooking time to 25-30 minutes total to prevent them from drying out. Thighs remain juicier due to their higher fat content.

→ How do I know when the chicken is fully cooked?

The chicken is done when the internal temperature reaches 75°C (165°F) and the juices run clear when pierced with a knife at the thickest part. The skin should be golden and crispy.

→ Can I prepare this traybake ahead of time?

Yes, you can prep all the vegetables and marinate the chicken up to 24 hours in advance. Store covered in the refrigerator, then assemble on the tray and roast when ready to cook.

→ What can I substitute for piri-piri seasoning?

Use a combination of smoked paprika, cayenne pepper, garlic powder, and dried oregano. Alternatively, try harissa paste, jerk seasoning, or your favorite spicy rub for different flavor profiles.

→ How should I store leftovers?

Store cooled leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in a 180°C oven for 15-20 minutes until piping hot throughout, or microwave in portions.

→ Can I add other vegetables to this traybake?

Absolutely! Courgettes, aubergine, butternut squash, or carrots work beautifully. Just ensure all vegetables are cut to similar sizes for even cooking and adjust timing if needed.
