Step-By-Step Instructions
- 1
First things first, let's get that oven fired up and ready to rock! Preheat your oven to a piping hot 200°C (180°C fan/Gas Mark 6). Grab your biggest baking tray – we want everything to have plenty of space to roast and get beautifully golden. Now, let’s get those veggies prepped! Wash and chop your baby potatoes, red onion, bell peppers, and zucchini. Remember, we're going for rustic chunks here, nothing too dainty, so they can stand up to the heat and get lovely and tender with those gorgeous caramelised edges. Don't forget to mince your garlic and roughly chop your fresh herbs, too; these are going to infuse everything with incredible flavour.

In a super big mixing bowl, combine your chopped potatoes, red onion, bell peppers, zucchini, and whole cherry tomatoes. Drizzle generously with the olive oil, then sprinkle over the minced garlic, fresh rosemary, fresh thyme, dried oregano, chilli flakes (if you're using them for that cheeky little kick!), and a good pinch of salt and pepper. Now, get your hands in there and give everything a really good toss! You want every single piece of veg to be beautifully coated in that oily, herby goodness. This ensures maximum flavour and a brilliant roast, so don't be shy – get stuck in!

Tip all those perfectly coated veggies onto your large baking tray, spreading them out into a single, even layer. This is crucial for them to roast properly and not steam. Pop the tray into your preheated oven and let them do their thing for about 15 minutes. During this time, they’ll start to soften, release their delicious aromas, and begin to get those lovely, slightly caramelised edges that we all adore. Keep an eye on them; we're building up layers of flavour here, so give them a little shake halfway through if you like, just to ensure even cooking.

Now for the star of the show – your lovely cooked chicken! After the vegetables have had their initial 15 minutes, carefully pull the baking tray out of the oven. Scatter your shredded or diced cooked chicken evenly over the partly roasted vegetables. Next, sprinkle over the zest of half your lemon and squeeze the juice from that same half directly over the chicken and veggies. Finally, arrange the thinly sliced lemon rounds from the other half of your lemon amongst the ingredients on the tray. Give it all a gentle stir to combine the chicken and lemon with the warming veggies, making sure everything is nestled nicely together.

Return the tray to the oven for another 10-12 minutes. During this final stretch, the chicken will heat through beautifully, absorbing all those fantastic lemon and herb flavours. The lemon slices will slightly caramelise, releasing their incredible aroma, and the vegetables will become perfectly tender and golden-brown, with some lovely crispy bits. You’ll know it’s ready when the chicken is piping hot all the way through, the vegetables are tender with a vibrant colour, and your kitchen smells absolutely divine! This is where the magic happens, so enjoy that incredible smell as it fills your home.

Once everything is cooked to perfection, carefully remove the tray from the oven. If you like, scatter a handful of fresh chopped parsley over the top for a final flourish of colour and freshness – it really makes it pop! Serve this incredible Lemon & Herb Leftover Chicken Traybake straight from the tray, family-style, with a big smile and maybe a cheeky glass of something lovely. It’s a brilliant, fuss-free meal that proves leftovers can be truly spectacular and bursting with flavour. Enjoy every single zesty, herby bite, my friends!

Jamie's Kitchen Tips
Right, my lovely home cooks, let's get into some of my top tips and tricks to make this Lemon & Herb Leftover Chicken Traybake an absolute showstopper, Jamie Oliver style! First off, don't be afraid to get creative with your veggies. This recipe is wonderfully versatile, so if you've got some sweet potato, broccoli florets, or even some forgotten mushrooms lurking in the fridge, chuck 'em in! Just remember to cut denser veggies like sweet potato into smaller pieces so they cook at the same rate as everything else. For a different flavour profile, swap the rosemary and thyme for fresh dill and mint – it gives a wonderfully Mediterranean vibe, especially if you add some crumbled feta at the end. If you're feeling a bit cheeky and want more heat, a little extra pinch of red chilli flakes or even a finely diced fresh red chilli would be brilliant. Remember, cooking is all about tasting as you go and adjusting to your own palate! Now, about that chicken! While this recipe is designed for cooked leftover chicken, if you've only got raw chicken breasts or thighs, you can absolutely adapt it. Just dice them up and add them to the tray at the very beginning with the veggies, giving them a good 20-25 minutes to cook through before the final 10-minute blast. And don't forget the power of good seasoning! A generous hand with salt and pepper truly makes all the difference, enhancing all those fresh flavours. If your dish ever tastes a bit 'flat,' a final squeeze of fresh lemon juice or a tiny sprinkle of flaky sea salt right before serving can magically lift everything. This traybake is also fantastic for meal prep; cook a double batch, and you've got delicious lunches or dinners ready to go for a couple of days. Just ensure it's cooled quickly before storing. Happy cooking, you superstars!
Substitutions & Variations
- Cooked turkey or pork can be used instead of chicken.
- Any mix of seasonal vegetables like butternut squash, parsnips, or broccoli florets can replace or supplement the suggested vegetables.
- Dried herbs can be used in place of fresh (use 1/3 the amount, as dried herbs are more potent).
Serving Suggestions
- Serve with a side of crusty artisan bread to mop up all the delicious juices.
- Pair with a simple green salad dressed with a light vinaigrette for extra freshness.
- Enjoy alongside a spoonful of fluffy couscous or quinoa for a heartier meal.
Storage & Reheating
Store any leftover Lemon & Herb Leftover Chicken Traybake in an airtight container in the refrigerator for up to 3 days. To reheat, you can warm it gently in the microwave until piping hot, or for best results, spread it out on a baking tray and reheat in a preheated oven at 180°C (160°C fan/Gas Mark 4) for 10-15 minutes, or until thoroughly heated through and crisping up again.
