Chicken and Sweet Potato Traybake

The smell of piri-piri hitting hot chicken skin is what hooked me on this dish. I'd been staring at a bag of sweet potatoes that had been sitting too long in my pantry, feeling uninspired by the same old mash routine. Then I remembered a meal I'd had at a tiny Portuguese cafe, where everything came out sizzling on one tray, charred at the edges and bursting with color. I threw it all together that evening without measuring much, and the kitchen filled with this smoky, garlicky warmth that made my flatmate wander in asking what smelled so good.

I made this for friends once after a long Saturday hike, when everyone was starving and too tired to wait for anything fancy. We sat around the kitchen table with the tray in the middle, pulling chicken off the bone and scooping up the caramelized sweet potato chunks with our forks. Someone squeezed lemon over everything at the last second, and the brightness just lifted the whole dish. It became the kind of meal people texted me about weeks later, asking for the recipe.

Ingredients

• Bone-in, skin-on chicken thighs: The skin crisps up beautifully in the oven and protects the meat from drying out, while the bone adds deeper flavor as everything roasts together.
• Piri-piri seasoning: This is your flavor engine, bringing smoky heat and a bit of tanginess that seeps into every corner of the tray.
• Sweet potatoes: They hold their shape when roasted and develop these sticky, caramelized edges that contrast perfectly with the spice.
• Red onion: Cut into thick wedges, they soften and sweeten in the oven, soaking up all the chicken juices and spices.
• Bell peppers: Use both red and yellow for color and a slight sweetness that balances the heat.
• Garlic: Sliced thin so it crisps slightly and scatters its flavor without burning.
• Cherry tomatoes: Added halfway through so they burst and release their juices without turning to mush.
• Fresh coriander or parsley: A handful of green at the end makes everything taste brighter and more alive.
• Lemon wedges: Essential for squeezing over just before eating, the acidity cuts through the richness and wakes up all the flavors.

Instructions

Preheat and Prep:

Set your oven to 200°C (180°C fan) and let it heat fully while you get everything ready. This ensures the chicken skin starts crisping the moment it hits the tray.

Season the Chicken:

In a large bowl, coat the chicken thighs with piri-piri seasoning, olive oil, smoked paprika, salt, and pepper, rubbing it into the skin and underneath if you can reach. The more you massage it in, the more flavor you lock into every bite.

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 top. Toss everything with your hands to coat evenly, then spread it out so nothing overlaps too much.

Nestle the Chicken:

Place the seasoned chicken thighs among the vegetables, skin-side up, pressing them gently into the mix. This lets the chicken juices drip down and flavor everything as it roasts.

First Roast:

Slide the tray into the oven and roast for 30 minutes without opening the door. The vegetables will start to soften and the chicken skin will begin to turn golden and crisp.

Add Tomatoes and Finish:

Scatter the halved cherry tomatoes across the tray and return it to the oven for another 10 minutes, until the chicken is cooked through and the tomatoes have burst. The juices should run clear when you pierce the thickest part of a thigh.

Garnish and Serve:

Pull the tray from the oven and let it rest for a minute, then scatter over fresh coriander or parsley and serve with lemon wedges on the side. Squeeze the lemon over everything just before eating for that bright, zingy finish.

There was one evening when I pulled this out of the oven just as the sun was setting, and the golden light caught the edges of the crispy chicken skin and the shiny peppers. My partner looked up from setting the table and said it looked like something from a magazine. We ate it straight from the tray with a bottle of cold white wine, and it felt less like dinner and more like a small celebration of nothing in particular.

Making It Your Own

If you like more heat, toss in some chili flakes or a sliced fresh chili with the vegetables before roasting. I've swapped the sweet potatoes for butternut squash when I had it on hand, and it worked just as well, going soft and sweet at the edges. You can also use chicken drumsticks or a mix of thighs and drumsticks if that's what you prefer, just check they're cooked through before pulling the tray out.

Serving Suggestions

This is hearty enough to eat on its own, but a crisp green salad with a sharp vinaigrette or some steamed green beans on the side adds freshness that balances the richness. I've also served it with warm flatbreads for mopping up the juices, and with couscous when I needed to stretch it for extra guests. A chilled Sauvignon Blanc or a light lager works beautifully alongside, cutting through the spice and complementing the sweetness of the vegetables.

Storage and Reheating

Leftovers keep well in the fridge for up to three days in an airtight container. I like to reheat individual portions in a hot oven or under the grill to crisp the chicken skin back up, though the microwave works in a pinch if you're just after a quick lunch. The flavors deepen overnight, so sometimes the next day's portion tastes even better.

• Let everything cool completely before storing to avoid condensation making the chicken soggy.
• You can freeze cooked portions for up to two months, just thaw overnight in the fridge before reheating.
• If reheating in the oven, add a splash of water to the tray and cover with foil to keep the chicken moist.

This dish has become my answer to those nights when I want something comforting but don't have the energy for complicated cooking. It's reliable, forgiving, and always fills the kitchen with the kind of smell that makes everyone hungry before it's even on the table.

Recipe Questions

→ Can I use chicken breasts instead of thighs?

Yes, boneless chicken breasts work well, though they may cook faster. Check for doneness after 25 minutes to prevent drying out. Thighs remain juicier due to their higher fat content.

→ What can I substitute for piri-piri seasoning?

Use a combination of smoked paprika, cayenne pepper, garlic powder, and lemon zest. Alternatively, try harissa paste or your favorite spicy rub for similar heat and flavor.

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

Insert a knife into the thickest part of the thigh; juices should run clear, not pink. Alternatively, use a meat thermometer - chicken is safe at 75°C (165°F) internal temperature.

→ Can I prepare this traybake ahead of time?

Yes, marinate the chicken and chop the vegetables up to 24 hours in advance. Store separately in the refrigerator, then assemble and roast when ready to cook.

→ What vegetables can I add or substitute?

Courgettes, aubergines, butternut squash, or parsnips all work beautifully. Just ensure vegetables are cut to similar sizes for even cooking. Add quicker-cooking options like courgettes halfway through.

→ How should I store leftovers?

Cool completely, then store 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.
