Sweet Chilli Chicken Traybake

Sweet Chilli Chicken Traybake

There are nights when you want a proper dinner, something bold, sticky, savoury and satisfying, but you absolutely do not want to stand at the hob juggling three pans. That is exactly where this Sweet Chilli Chicken Traybake earns its place.

This is fuss free cooking that still delivers serious flavour. Juicy chicken thigh fillets roasted in a sweet chilli and soy marinade, fresh garlic and ginger baked until fragrant, and tender greens soaking up all those glossy, sticky tray juices. It is the kind of easy chicken traybake recipe that tastes like you’ve made an effort, even though the oven has done most of the work.

Sweet chilli chicken is one of those flavours that just works. It hits sweet, salty, slightly spicy and deeply savoury all at once. The soy sauce adds umami depth, the ginger keeps it fresh, the garlic rounds it out, and the sesame oil drizzled over the vegetables at the end adds that unmistakable nutty finish.

If you’re looking for a simple weeknight chicken dinner, an easy traybake with chicken thighs, or a sweet chilli chicken recipe that actually has flavour, this one does the job properly.

Why this sweet chilli chicken traybake works so well

Traybakes are popular for a reason. They’re practical. Everything cooks together. There’s minimal washing up. But the key to a good traybake is balance. You need flavour, texture and enough moisture so nothing dries out.

Chicken thighs are the right choice here. Unlike chicken breast, thighs stay juicy under high heat. They absorb marinade beautifully and give you that slightly sticky, caramelised exterior when roasted.

The sweet chilli sauce provides sweetness and gentle heat. It also helps create that glossy finish once it reduces in the oven.

Soy sauce seasons the chicken deeply and adds saltiness without needing loads of extra seasoning.

Garlic and ginger bring warmth and complexity. Together, they give this traybake its Asian-inspired edge.

Adding the pak choi and tenderstem broccoli halfway through cooking is important. It keeps them vibrant and tender, not overcooked and soggy. The vegetables absorb the tray juices and sesame oil, turning them into something far more interesting than plain steamed greens.

The result is a balanced chicken traybake with sticky edges, tender meat and properly flavoured vegetables.

A quick history of traybake dinners

Traybake cooking, sometimes called sheet pan cooking in the US, became popular in British home kitchens as a practical solution to busy evenings. The idea is simple: everything goes onto one tray and into the oven.

While traditional British traybakes often include sausages, root vegetables and gravy flavours, modern versions borrow heavily from global cuisines. Sweet chilli chicken is a perfect example of that evolution, combining Asian-inspired flavours with a classic British cooking method.

This dish sits comfortably between cultures. It is familiar enough for a weeknight family dinner but bold enough in flavour to feel interesting.

Ingredients

6 chicken thigh fillets
4 cloves of garlic, chopped
20 g fresh ginger, chopped
4 tbsp soy sauce
6 tbsp sweet chilli sauce
2 pak choi, cut in half
150 g tenderstem broccoli
1 tbsp sesame oil

Salt and black pepper if needed
Sticky rice, to serve

How to make sweet chilli chicken traybake

Preheat your oven to 200C fan.

Place the chicken thigh fillets into a bowl. Add the chopped garlic, chopped ginger, soy sauce and sweet chilli sauce. Mix thoroughly so the chicken is completely coated.

Lay the chicken into an ovenproof dish or tray in a single layer. Pour over any remaining marinade from the bowl.

Bake for 20 minutes.

Remove the tray from the oven. Arrange the halved pak choi and tenderstem broccoli around the chicken. Drizzle the vegetables with sesame oil.

Return the tray to the oven and bake for a further 10 minutes, or until the chicken is cooked through and the vegetables are tender but still vibrant.

Serve with sticky rice and spoon over the tray juices.

Tips for the best sweet chilli chicken traybake

Use skinless boneless chicken thighs for maximum juiciness.

Do not overcrowd the tray. Space allows proper caramelisation.

If you want extra colour, switch the oven to grill for the final 2 to 3 minutes.

Always check the internal temperature of the chicken reaches 75C.

If your sweet chilli sauce is very mild, add a pinch of chilli flakes.

Variations and substitutions

Swap chicken thighs for drumsticks if preferred, adjusting cooking time.

Use broccolini, green beans or sugar snap peas instead of tenderstem broccoli.

Add sliced red peppers or red onion for extra sweetness.

Stir a teaspoon of honey into the marinade if you want it stickier.

Make it gluten free by using tamari instead of regular soy sauce.

For a lower sugar version, use reduced sugar sweet chilli sauce.

What to serve with sweet chilli chicken

Sticky jasmine rice is ideal because it soaks up the juices.

Egg fried rice works brilliantly if you want something heartier.

You could also serve it with noodles tossed in a little sesame oil.

If you like this kind of fuss free traybake, you might also enjoy Korean Fried Chicken or Sweet & Spicy Chicken Tenders for similar flavour profiles.

Storage and leftovers

Store leftovers in an airtight container in the fridge for up to 3 days.

Reheat in the oven at 180C until warmed through, or microwave gently.

This traybake is excellent for meal prep. Portion with rice and greens for ready-made lunches.

Freezing is possible for the chicken, though the vegetables are best eaten fresh.

FAQs

Can I use chicken breast instead of thighs?
Yes, but reduce the cooking time slightly and watch carefully to avoid drying it out.

Is this sweet chilli chicken spicy?
It is mildly spicy. The heat level depends on your sweet chilli sauce. Add fresh chilli if you prefer more heat.

Can I marinate the chicken in advance?
Absolutely. Marinate for up to 24 hours in the fridge for deeper flavour.

Do I need to cover the tray?
No. Roasting uncovered helps caramelise the sauce and create those sticky edges.

Can I cook this in an air fryer?
Yes. Cook the chicken at 190C for around 15 to 18 minutes, adding vegetables halfway through.

How do I know the chicken is cooked?
The juices should run clear and the internal temperature should reach 75C.
