Chicken and Sweet Potato Traybake

The smell of piri-piri hitting hot oil always takes me straight back to a Tuesday evening when I had absolutely nothing planned for dinner. I'd grabbed a jar of the seasoning on a whim weeks earlier, and there it sat, waiting for exactly this kind of moment. I tossed chicken and whatever vegetables looked decent onto one tray, slid it into the oven, and by the time I'd changed out of work clothes, my kitchen smelled like a Portuguese grill. That lazy decision became the meal I now make whenever I need something vibrant, filling, and completely unfussy.

I made this for friends once when they showed up earlier than expected, and I was still in my slippers with the tray half-assembled. We stood around the kitchen with wine glasses while it roasted, and by the time it came out golden and sizzling, they were convinced I'd been cooking all afternoon. The truth is, the oven did the work, and the piri-piri made it look impressive.

Ingredients

• Bone-in, skin-on chicken thighs: These stay moist and flavorful during roasting, and the skin crisps up beautifully against the hot tray.
• Piri-piri seasoning: This is your flavor foundation, a smoky, slightly spicy blend that transforms simple chicken into something memorable.
• Sweet potatoes: They caramelize at the edges and soak up all the savory juices from the chicken as everything roasts together.
• Red onion: Cut into thick wedges, they soften and sweeten in the oven, adding depth without disappearing into mush.
• Red and yellow bell peppers: These bring color, a hint of sweetness, and a satisfying bite that balances the richness of the chicken.
• Cherry tomatoes: Added toward the end, they burst and release their juices, creating a light, tangy sauce that pools around everything.
• Garlic: Thinly sliced so it crisps slightly and flavors the oil that coats the vegetables.
• Smoked paprika: Adds an extra layer of warmth and a subtle smokiness that complements the piri-piri perfectly.

Instructions

Preheat and Prep:

Set your oven to 200°C and give it time to reach full heat while you prep. A properly hot oven ensures the chicken skin crisps and the vegetables caramelize instead of steaming.

Season the Chicken:

In a large bowl, coat the chicken thighs thoroughly with piri-piri seasoning, olive oil, smoked paprika, salt, and pepper. Use your hands to massage it into the skin so every bite has that bold, smoky flavor.

Arrange the Vegetables:

Spread the sweet potatoes, onion, and peppers across a large baking tray in a single layer, then drizzle with olive oil and scatter over the garlic. Toss everything together so the oil coats evenly and the garlic nestles among the vegetables.

Nestle the Chicken:

Place the seasoned chicken thighs skin-side up among the vegetables, making sure they sit directly on the tray for maximum crisping. The juices will drip down and flavor everything as it roasts.

Roast Until Golden:

Slide the tray into the hot oven and roast for 30 minutes without touching it. The chicken will start to brown and the vegetables will soften and take on color at the edges.

Add the Tomatoes:

Scatter the halved cherry tomatoes over the tray and return it to the oven for another 10 minutes. The tomatoes will blister and burst, creating pockets of sweet, tangy juice.

Garnish and Serve:

Once the chicken is cooked through and the vegetables are tender, scatter over fresh coriander or parsley and serve with lemon wedges. Squeeze the lemon over everything just before eating for a bright, zesty finish.

One evening, I served this with nothing but a chunk of crusty bread and a simple green salad, and my partner looked up halfway through and said it tasted like we were on holiday. It wasnt fancy, but the colors, the heat, the way everything tasted like it belonged together, it felt like more than just dinner on a Wednesday.

Making It Your Own

If you want more heat, toss in a pinch of chili flakes or a sliced fresh chili with the vegetables before roasting. I sometimes swap the sweet potatoes for butternut squash when I have it, or use a mix of root vegetables like parsnips and carrots for a different sweetness. The beauty of this recipe is that it adapts to whatever looks good at the market or sits waiting in your fridge.

What to Serve Alongside

This dish is hearty enough to stand on its own, but a crisp green salad with a sharp vinaigrette cuts through the richness beautifully. Steamed green beans or tenderstem broccoli add a fresh, bright contrast, and if you want something more substantial, a bowl of couscous or warm flatbreads will soak up all those lovely pan juices. A chilled Sauvignon Blanc or a light lager is perfect for balancing the smoky, spicy flavors.

Storage and Reheating

Leftovers keep well in an airtight container in the fridge for up to three days, and they taste even better the next day once the flavors have mingled. Reheat gently in a low oven to keep the chicken skin from going soggy, or warm portions in a pan with a splash of water to bring everything back to life. I sometimes shred the leftover chicken and toss it with the vegetables and a handful of salad leaves for a quick lunch that feels completely different.

• Store chicken and vegetables together so the juices keep everything moist.
• Reheat in a 160°C oven for 15 minutes rather than using the microwave if you want to preserve texture.
• Freeze individual portions in freezer-safe containers for up to two months and defrost overnight in the fridge.
