Chicken Sweet Potato Traybake

The first time I made this traybake, my flatmate wandered into the kitchen saying something smelled like a Portuguese holiday. I had no reference point, but the mix of piri-piri spice hitting roasting sweet potatoes filled the entire apartment. We ended up eating straight from the tray, standing by the counter, because waiting to plate it seemed unnecessary.

Last summer, I made this for a friend who claimed to hate meal-prep containers. She took one bite of the leftover chicken the next day and texted me asking for the recipe immediately. The way the flavors deepen overnight actually makes it better, which I have confirmed through extensive lunch testing.

Ingredients

• Chicken thighs with bone and skin: The bone keeps the meat juicy and the skin crisps up beautifully while protecting the meat from drying out
• Piri-piri seasoning or paste: This African chile blend brings heat and complexity, though you can adjust the amount based on your spice tolerance
• Olive oil: Helps the spices coat everything evenly and encourages that gorgeous roasting color
• Smoked paprika: Adds a subtle smoky depth that complements the bright piri-piri flavors
• Sweet potatoes: Their natural sweetness balances the heat and they hold their shape well through roasting
• Red onion: Becomes sweet and mellow when roasted, adding color and depth to the dish
• Bell peppers: Use both red and yellow for visual appeal and slightly different sweet notes
• Garlic cloves: Slice them thinly so they roast alongside the vegetables without burning
• Cherry tomatoes: Added later in the cooking time so they burst rather than disintegrate completely
• Fresh herbs and lemon: These brighten the rich roasted flavors at the very end

Instructions

Preheat and prep:

Heat your oven to 200°C (180°C fan) while you gather your largest baking tray and mixing bowl

Season the chicken:

Toss the chicken thighs with piri-piri seasoning, olive oil, smoked paprika, salt, and pepper until every piece is evenly coated

Arrange the vegetables:

Spread the sweet potatoes, onion wedges, bell peppers, and sliced garlic on your baking tray, drizzle with a little oil, and toss to coat

Nestle in the chicken:

Place the seasoned chicken thighs among the vegetables, skin-side up, so the fat can render down over everything while roasting

First roast:

Cook for 30 minutes until the chicken skin is starting to crisp and the vegetables are beginning to soften

Add tomatoes:

Scatter the halved cherry tomatoes over the tray and return to the oven for another 10 minutes

Finish and serve:

The chicken is done when juices run clear and vegetables are golden, then scatter with fresh herbs and serve with lemon wedges

Pin It

My sister accidentally used butternut squash instead of sweet potatoes once and declared it an upgrade. Now I keep both on hand depending on what looks best at the market, but the sweetness of either vegetable against the spicy chicken is what makes this combination work so well.

Making It Your Own

Sometimes I add baby corn or courgette halves if I need to stretch the dish to feed more people. The vegetables that take longer to cook go in at the start, while quicker-cooking ones join the tray with the tomatoes.

Serving Suggestions

A crisp green salad with a sharp vinaigrette cuts through the richness perfectly. Steamed green beans work beautifully too and add another color to the plate.

Leftover Wisdom

This reheats exceptionally well for lunch the next day. The flavors meld together overnight and the chicken stays moist.

• Store in an airtight container for up to three days
• Reheat at 180°C until piping hot throughout
• The skin will not be as crisp after reheating, but the meat remains delicious

There is something deeply satisfying about a complete meal that requires nothing more than one pan and a hungry appetite.

Recipe Questions & Answers

→ Can I adjust the spice level of this dish?

Absolutely. For extra heat, you can add a pinch of chili flakes or finely sliced fresh chili along with the vegetables when roasting. If you prefer milder flavors, reduce the amount of piri-piri seasoning or use a mild variety.

→ What other vegetables work well in this traybake?

This dish is quite versatile. Instead of sweet potatoes, you could use butternut squash or mixed root vegetables like parsnips and carrots. Broccoli florets, zucchini, or even asparagus can be added during the last 15-20 minutes of cooking for variety.

→ Is this a good option for meal prepping?

Yes, it's excellent for meal prepping. The cooked chicken and vegetables store well in an airtight container in the refrigerator for up to 3-4 days. You can easily reheat portions in the microwave or oven.

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

The chicken is cooked through when its internal temperature reaches 74°C (165°F) at the thickest part. If you don't have a thermometer, pierce the thickest part of the thigh; the juices should run clear, with no pinkness remaining.

→ Can I use boneless, skinless chicken for this traybake?

You can, but cooking times will vary. Boneless, skinless chicken thighs will cook faster, likely needing around 20-25 minutes total. Ensure they are cooked through and the vegetables are tender, adjusting the timing as needed.

→ What are some good serving suggestions for this meal?

This dish is a complete meal on its own, but you can serve it with a crisp green salad or steamed green beans for added freshness. A side of couscous or quinoa would also complement the flavors and add more substance.
