Can a chicken dinner feel fresh and healthy without turning into a salad?

This lemon herb chicken does, especially with roasted peppers, courgette, red onion and juicy tomatoes all sharing the same plate. 

 

I could happily eat the roasted vegetables from this on their own.

The peppers soften and sweeten in the oven, the tomatoes get juicy around the edges, and the red onion catches a little colour without losing all of its bite.

Then the chicken goes on top, sliced thick and covered in lemon, herbs, garlic and all those good juices from cooking.

It’s a really simple plate, but there’s plenty going on once everything gets mixed together.

Some bites are sharp with lemon, some are sweeter from the peppers and tomatoes, and every now and then you get one of those browned pieces of courgette that has soaked up half the dressing.

I usually spoon whatever is left in the pan straight over the top before serving.

No complicated sauce needed.

 

What You’ll Need

For the chicken

• 4 boneless skinless chicken breasts
• 1 tablespoon olive oil
• 1 teaspoon dried oregano
• 1 teaspoon garlic powder
• 1/2 teaspoon dried thyme
• 1/2 teaspoon paprika
• 1 teaspoon salt
• 1/2 teaspoon black pepper

For the roasted vegetables

• 2 medium zucchini, sliced into thick rounds
• 2 red bell peppers, sliced into wide strips
• 250 g cherry tomatoes
• 1 large red onion, cut into wedges
• 2 tablespoons olive oil
• 1/2 teaspoon dried oregano
• Salt, to taste
• Black pepper, to taste

For the lemon olive oil dressing

• 3 tablespoons extra virgin olive oil
• 2 tablespoons fresh lemon juice
• 1 teaspoon finely grated lemon zest
• 1 garlic clove, finely grated
• 1 tablespoon chopped fresh parsley
• 1/2 teaspoon dried oregano
• Pinch of salt
• Black pepper, to taste

To finish

• 2 to 3 tablespoons chopped fresh parsley
• Lemon wedges, optional

The vegetables need space

I know it is tempting to put everything on one small tray because fewer dishes sounds attractive.

Then the vegetables steam in a pile and you wonder where all the lovely roasted edges went.

Use a large tray.

Two trays are even better if yours are small.

Zucchini especially needs room because it contains a lot of water.

You want the slices touching the hot tray rather than sitting underneath peppers and onions having a little sauna.

The tomatoes can stay whole.

They will blister and soften on their own, and a few may split open and release some juice.

That juice mixing with the olive oil is not a problem.

That is flavour.

How to Make It

Roast the vegetables

• Heat the oven to 220°C / 200°C fan / 425°F.
• Add the zucchini, red peppers, cherry tomatoes and red onion to a large roasting tray.
• Drizzle over the olive oil.
• Add the oregano, a good pinch of salt and black pepper.
• Toss everything well.
• Spread the vegetables into a fairly even layer.
• Roast for 20 to 25 minutes.
• Turn the vegetables once halfway through cooking.
• Remove them when the peppers and onions are soft, the zucchini has browned around the edges and the tomatoes are blistered.

Season the chicken

• Pat the chicken breasts dry with kitchen paper.
• In a small bowl, mix the oregano, garlic powder, thyme, paprika, salt and black pepper.
• Rub the chicken with the olive oil.
• Sprinkle the seasoning evenly over both sides.

Cook the chicken

• Heat a large frying pan over medium-high heat.
• Add the chicken breasts.
• Cook for about 5 to 7 minutes on the first side without constantly moving them.
• Turn and cook for another 5 to 7 minutes, depending on thickness.
• Reduce the heat slightly if the outside is browning too quickly.
• Cook until the centre reaches 75°C / 165°F.
• Transfer the chicken to a plate or board.
• Let it rest for 5 to 10 minutes before slicing.

Make the lemon dressing

• Add the olive oil, lemon juice, lemon zest, grated garlic, parsley, oregano, salt and black pepper to a small bowl.
• Whisk until combined.
• Taste it.
• Add another squeeze of lemon if you want it sharper.

Put everything together

• Arrange the roasted vegetables on a large serving plate or individual plates.
• Slice the rested chicken breast into thick pieces.
• Place the chicken over the vegetables.
• Spoon the lemon olive oil dressing generously over the chicken and vegetables.
• Scatter over the chopped parsley.
• Serve immediately.

 

 

Leave the chicken alone for a minute

There is a point during pan-frying chicken when people start poking it every eight seconds because nothing appears to be happening.

Something is happening.

Leave it there.

That uninterrupted contact with the pan is what gives the chicken those golden seared patches.

If you keep lifting it to inspect the underside, you interrupt the browning and usually make the cooking take longer.

Once the first side is properly golden, turn it.

Then do the same thing again.

Very little drama required.

Chicken breast does not need punishment

Dry chicken breast usually comes from fear.

Someone thinks it might not be cooked, so it gets another five minutes.

Then another two.

Then perhaps a final minute “just in case.”

By then the poor thing has given up.

A thermometer makes this much easier.

Once the thickest part reaches 75°C / 165°F, take it off the heat.

Then let it rest.

Resting is not pointless chef theatre.

It gives the juices a chance to settle back through the meat instead of pouring straight onto the chopping board when you slice it.

The zucchini should still look like zucchini

I do not want the zucchini dissolving into the tray.

Slice it fairly thickly.

Around 1 cm works well.

It will soften during roasting while still keeping its shape.

The browned edges are especially good because they give a little contrast to the softer centre.

If you cut the zucchini paper-thin, it tends to collapse before the peppers are ready.

Save that treatment for another recipe.

Red onion changes completely in the oven

Raw red onion is sharp.

Roasted red onion is almost sweet.

That is why it works so well here.

Cut it into wedges rather than tiny pieces.

The edges will darken while the thicker sections soften.

It also looks much better mixed through the zucchini, tomatoes and red peppers than a pile of finely diced onion would.

I like leaving some of the layers joined together during roasting.

They separate naturally once everything gets tossed.

Do not make the dressing too complicated

Lemon, olive oil, garlic, herbs.

That is enough.

It is supposed to taste fresh and sharp against the roasted vegetables and chicken.

I would not add cream, mayonnaise or anything heavy here.

The olive oil gives the dressing body, while the lemon cuts through the richness from the roasted vegetables and chicken juices.

The zest is useful because it adds lemon flavour without adding more acidity.

If your lemon is especially sour, start with slightly less juice.

You can always add more.

Cherry tomatoes are doing more than adding colour

Once they roast, they become softer and sweeter and start releasing their juices.

Those little pockets of tomato juice mix with the dressing beautifully.

I would not cut every tomato in half before roasting because they can collapse too much.

Leave most of them whole.

If a few are unusually large, halve those.

The goal is to have actual pieces of tomato left when everything reaches the plate.

What I would serve with this

You do not necessarily need anything else.

The chicken and vegetables make a full meal.

But if you want something more substantial, a few options work well:

• Fluffy white rice
• Couscous
• Roasted baby potatoes
• Crusty bread
• Quinoa
• A simple green salad

Rice is especially useful if you like plenty of lemon dressing because it catches everything at the bottom of the plate.

Bread performs the same service with considerably less dignity.

Both are valid.

Can you cook the chicken in the oven instead?

Yes.

If you want everything oven-based, place the seasoned chicken breasts on a separate tray and roast them at 200°C / 180°C fan / 400°F.

Depending on thickness, they will usually need around 18 to 25 minutes.

Again, use the internal temperature rather than blindly trusting the clock.

I prefer pan-searing because you get more colour on the chicken, but oven-roasting is convenient if you do not want another pan on the hob.

Leftovers are actually useful

This chicken is good cold too.

Slice leftover chicken and add it to a salad the following day with the roasted vegetables.

You can also put everything into a wrap with a little yogurt or hummus.

Or reheat it and serve with rice.

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

I would keep any extra dressing separate if possible.

When reheating chicken breast, go gently.

It is already cooked.

You are warming it, not giving it a second career.

Q&A

Can I use chicken thighs instead of chicken breast?

Yes.

Boneless skinless chicken thighs work very well and stay especially juicy.

They may need a few extra minutes depending on thickness.

Can I use yellow peppers instead?

Yes.

Yellow or orange peppers both work.

I like red peppers here because they become particularly sweet when roasted.

Can I add more vegetables?

Yes.

Aubergine, mushrooms or asparagus would all work.

Just keep the tray from becoming overcrowded.

Can I prepare the vegetables ahead?

Yes.

You can slice the zucchini, peppers and onion several hours ahead and keep them covered in the fridge.

Leave the tomatoes whole until you are ready to cook.

Can I make the lemon dressing ahead?

Yes.

Make it up to a day ahead and refrigerate it.

Bring it back toward room temperature and whisk again before serving because the olive oil may thicken in the fridge.

Why is my zucchini watery?

It was probably overcrowded or sliced too thinly.

Use a large tray, keep the pieces fairly thick and roast at a high temperature.

Can I use dried parsley?

I would use fresh parsley for finishing this dish.

Dried parsley does not give the same fresh flavour or appearance.

You can use dried herbs in the chicken seasoning, though.

Can I grill the chicken instead?

Absolutely.

Cook it over medium-high heat until nicely marked and cooked through.

The lemon dressing works especially well with grilled chicken.

Is this good for meal prep?

Yes.

Keep the chicken, vegetables and dressing in separate containers if possible.

That keeps the vegetables from becoming too soft.

Can I use bottled lemon juice?

Fresh is much better here.

The dressing is simple enough that the lemon flavour is noticeable, so fresh juice and zest make a real difference.
