A whole roast chicken and a potato bake in the same dish. The potatoes go in the bottom with sliced onion and lemon and a creamy French onion sauce poured over them, then the chicken sits on top and cooks for an hour.
Everything that comes out of the chicken drips into the potatoes, which is the whole idea. You get roast chicken and the best potato bake you’ve had, without running two dishes.
It feeds four with one dish to wash, and it looks like you went to a lot more trouble than you did.
Why You’ll Love It
A whole chicken is one of the cheapest ways to feed four people, and this uses one dish for the lot. The French onion sachet and 300ml of cream make the potato sauce with nothing to whisk, and slicing the potatoes thin plus a 10-minute head start in the microwave is what makes an hour long enough. There’s no basting, no turning, no watching it.
The Shortcut That Makes It Work
Two shortcuts stacked. The potatoes go in the microwave with a splash of water for 10 minutes first, which means they’re already soft when they go in the oven, and the French onion soup sachet mixed with cream is the whole sauce. Butterflying the chicken flattens it so it cooks in an hour instead of the hour and a half a whole bird usually wants.
Handy Tips
Slice the potatoes thin, a mandolin is easiest but a knife is fine, because thick slices won’t be cooked when the chicken is. Make sure every potato slice is coated in the cream mixture or the top ones dry out. Butterfly the chicken, which just means cutting down the backbone and pressing it flat, and season the skin properly with salt and pepper. It goes in at 180°C fan-forced for about an hour, and you want the chicken golden and the potatoes soft before it comes out. Let it sit for a few minutes before you carve.
Make It Your Way
Swap the sweet potato for another regular potato if that suits your house better, or add sliced fennel or leek in with the onion. If you’d rather not deal with a whole bird, chicken thighs on top of the same potato base work well and cook faster.
What To Serve With It
Steamed broccoli is what the recipe suggests and it’s the right call, since the dish is already rich. Green beans, peas or a simple salad all do the same job.
Leftovers / How to Store It
Pull the chicken off the bones and keep it with the potatoes in an airtight container in the fridge for up to three days. Reheat it covered so the chicken doesn’t dry out. Any leftover chicken is good in sandwiches or through a salad the next day.

FAQs
What does butterflying the chicken mean?
Cutting out the backbone so the bird lies flat. It cooks faster and more evenly that way, and it means the whole underside sits against the potatoes. Any butcher will do it for you if you’d rather not.
Can I use chicken pieces instead of a whole chicken?
Yes. Thighs or drumsticks on top of the same potato base work well and cook faster than a whole bird, so keep an eye on it.
Do I have to precook the potatoes?
Yes, don’t skip it. The chicken is only in there for an hour, and raw sliced potato won’t be soft in that time even sliced thin.
Can I make the potato base ahead?
You can slice the potatoes and mix the cream sauce earlier in the day and keep both in the fridge. Assemble and bake when you’re ready, since sliced potato sitting in the sauce for too long starts to discolour.
Why is my potato dry on top?
The top layer wasn’t coated. Make sure the cream mixture gets right through the potatoes rather than just sitting on the surface, and the chicken above will do the rest.
