One Tray. Big Flavor. Super Crispy.
Hey friends!
Tonight, I’m making something I know you’ll love One Tray Crispy Chicken and Potato Roast. This dish is a total weeknight winner. It’s cozy, crispy, and packed with flavor in every bite. The best part? Everything goes on one tray less mess, less stress! The secret to that golden crunch is using a shallow baking tray, not a deep one. That way, everything roasts up instead of steaming.
Let’s jump in and make dinner extra special tonight!
Method
Preheat the Oven
First things first, preheat your oven to 200°C fan or 220°C if you’re using a regular oven. Starting with a hot oven is important it helps the chicken skin and potatoes get that perfect golden crunch from the very beginning.
Mix the Flavor Coating
In a small mixing bowl, combine your 3 tablespoons of cornflour with 1 heaped teaspoon of sweet smoked paprika, 1 heaped teaspoon of pul biber (or chili flakes), 2 teaspoons of garlic granules, and 2 teaspoons of dried oregano. This dry mix will be the key to building a crisp, flavorful coating that sticks to everything once the oil is added later.
Load Up the Tray
Now grab your large shallow baking tray this part is important. A shallow tray helps the heat hit the ingredients directly, giving you crispy edges instead of soft, steamed results. Place your chicken thighs, chunky-cut potatoes, and quartered onions into the tray. Be sure the pieces are not on top of one another each bit should have room to roast properly.
Coat with Spice Mix
Sprinkle the spice and cornflour mixture over the chicken, potatoes, and onions right inside the tray. Using your clean hands, gently toss and turn the ingredients to coat them evenly in the dry mix. Try to make sure each surface is covered this helps with flavor and crispiness later.
Add the Olive Oil
Next, pour the 4 tablespoons of olive oil over everything in the tray. Again, use your hands to massage the oil into the coated ingredients. What you’re doing here is turning the dry mix into a kind of paste that sticks really well to the chicken skin and potato chunks. You’ll know it’s ready when you no longer see dry powder just a nice, glistening coating all over.
Final Touches Before Roasting
Wash your hands well after mixing, then sprinkle 1 teaspoon of sea salt flakes and ¾ teaspoon of coarse black pepper evenly across the tray. Finally, nestle in a few sprigs of fresh rosemary between the chicken and potatoes. The rosemary will infuse the whole dish with a warm, herby aroma while roasting.
Time to Roast
Place the tray on the middle shelf of your preheated oven. Let it roast for 30 minutes without touching anything. This is when the magic starts everything will begin to brown and sizzle.
Flip the Potatoes
After the first 30 minutes, carefully take the tray out. Use a spatula or tongs to flip only the potatoes to help them crisp evenly on all sides. Do not flip or move the chicken thighs leaving them undisturbed helps the skin stay perfectly crisp. Then return the tray to the oven for another 30 minutes.
Check for Crispiness
Once the full hour of cooking is done, check that the chicken is golden brown and crispy, and that the potatoes are soft in the middle with crispy edges. If everything looks just right, your dinner is ready to serve!

- Wash your hands, then sprinkle salt and pepper all over the tray. Tuck in your rosemary sprigs.

Notes
- Don’t overcrowd the tray. If the chicken and potatoes are too close, they’ll steam instead of roast.
- Don’t skip mixing with your hands. It’s the best way to coat everything evenly.
- Don’t flip the chicken. It crisps better when you leave it alone. Only flip the potatoes halfway through.
