Cajun Chicken Traybake with Sweet Potato & Zucchini
One bowl of garlic, olive oil, lime, and four spices turns into two things: a chicken marinade and a vegetable glaze. Both go on the same sheet, both roast for 20 minutes, and both come out with that smoky, slightly charred edge that makes a traybake worth the oven preheat.
The sweet potato chunks caramelize where they touch the parchment. The bell pepper strips soften without going limp. The zucchini picks up color on the cut sides. And the chicken, rubbed with the same Cajun mix, finishes right alongside everything else. No staging, no sequence, no second pan.

Ingredients
- bell pepper 1
- zucchini 1
- sweet potato 0.5 pound
- red onion 0.25
- garlic 1 clove
- olive oil 2 tablespoons
- lime juice 1 squeeze
- paprika (ground spice) 1 teaspoon
- oregano, dried 1 teaspoon
- thyme, dried 1 teaspoon
- chili powder 1 pinch
- chicken breast 3 ounces
Method
-
Preheat the oven to 390°F (200°C).
-
Halve the bell pepper, remove the seeds and cut into strips. Slice the zucchini and then halve the slices. Wash the sweet potato well and pat dry with paper towels. Cut into large chunks. Cut the red onion into wedges. Press the garlic clove.
-
In a small bowl, mix the garlic, oil, lime juice, paprika powder, oregano, thyme, chili powder and some pepper and salt.
-
Mix half of the marinade with the chicken breast in a small bowl and rub it well into the chicken.
-
In another bowl, mix the bell pepper, zucchini, sweet potato and onion with the other half of the marinade.
-
Line a baking sheet with parchment paper. Place the chicken breast on the baking sheet and arrange the vegetables around it.
-
Place the baking sheet in the oven and roast everything for 20 minutes until cooked through.
-
Serve the traybake on a plate.
Make sure every sweet potato chunk gets a full coating of the olive oil marinade before it hits the sheet. Research found that cooking sweet potato with oil made the beta-carotene up to 20 times more available for absorption than cooking without fat.
Beta-carotene dissolves in fat, not water. Your body needs fat present during digestion to actually absorb it. A 2009 study tested heat-processed sweet potato with and without cooking oil. With oil, absorption jumped from about 1% to between 11 and 22%. The oven heat breaks down the cell walls of the sweet potato, releasing the beta-carotene that was locked inside. The olive oil gives it something to dissolve into so your gut can pick it up.
Why This Works
Behind this recipe
Can I use regular potatoes instead of sweet potato?
You can, and the recipe will still work. The macros will shift slightly (regular potatoes have less fiber and no beta-carotene), but the cooking method and timing stay the same. Sweet potato is used here partly for its beta-carotene content, which the olive oil and oven heat make significantly more available for absorption.
Can I make this spicier?
The recipe uses just a pinch of chili powder (1g). You can increase that to half a teaspoon or more, or add cayenne pepper to the spice mix. The other spices (paprika, oregano, thyme) balance the heat, so the Cajun flavor holds even if you go heavier on chili.
Is 3 ounces of chicken enough protein?
The full meal delivers 29g of protein from the chicken and the vegetables combined. If you want more protein per serving, you can scale the chicken up to 5 or 6 ounces without changing the roasting time or temperature.
