A one-pot Chicken recipe with British flavors, built for busy weeknights when you want real food without a sink full of dishes. Comes together in roughly 48 minutes, serves about 4, and uses ingredients you can find at any normal grocery store. The technique is simple: build a base in your pot, layer in the main ingredients, simmer until everything has had time to talk to each other, and serve straight from the pan. If you're cooking for picky eaters, this one tends to land — the flavors are recognizable, the texture is comforting, and there's nothing weird hiding in the ingredient list. Perfect for the kind of evening where you want dinner on the table by 7pm and the kitchen empty by 7:30.

Ingredients

Makes 4 servings · 43 min total

50g Butter
1 chopped Onion
100g Mushrooms
40g Plain Flour
1 Chicken Stock Cube
pinch Nutmeg
pinch Mustard Powder
250g Chicken
2 Handfuls Sweetcorn
2 large Potatoes
1 knob Butter

Step-by-step instructions

Heat oven to 200C/180C fan/gas 6. Put the butter in a medium-size saucepan and place over a medium heat. Add the onion and leave to cook for 5 mins, stirring occasionally. Add the mushrooms to the saucepan with the onions.
Once the onion and mushrooms are almost cooked, stir in the flour – this will make a thick paste called a roux. If you are using a stock cube, crumble the cube into the roux now and stir well. Put the roux over a low heat and stir continuously for 2 mins – this will cook the flour and stop the sauce from having a floury taste.
Take the roux off the heat. Slowly add the fresh stock, if using, or pour in 500ml water if you’ve used a stock cube, stirring all the time. Once all the liquid has been added, season with pepper, a pinch of nutmeg and mustard powder. Put the saucepan back onto a medium heat and slowly bring it to the boil, stirring all the time. Once the sauce has thickened, place on a very low heat. Add the cooked chicken and vegetables to the sauce and stir well. Grease a medium-size ovenproof pie dish with a little butter and pour in the chicken and mushroom filling.
Carefully lay the potatoes on top of the hot-pot filling, overlapping them slightly, almost like a pie top.
Brush the potatoes with a little melted butter and cook in the oven for about 35 mins. The hot-pot is ready once the potatoes are cooked and golden brown.

Why this works on a weeknight

Chicken & mushroom Hotpot lands at about 43 minutes total — a little longer than our 30-minute target, but most of that time is hands-off simmering, which is why it earned a spot in our Sheet-Pan Dinners collection. The technique is forgiving, the ingredient list is grocery-store standard, and the active cooking time is short enough that you can answer a text message in the middle without ruining dinner.

Cleanup notes

This is a single-pan recipe, so the cleanup is exactly one pan, one cutting board, and one knife. While the dish rests, fill the pan with hot soapy water — by the time you are done eating, the residue lifts off with a single pass of a sponge. Skip the steel wool on cast iron; a stiff brush and warm water are all you need to keep the seasoning intact.

Make-ahead and leftovers

Leftovers keep covered in the fridge for up to three days. Reheat in a dry pan over medium-low with a splash of water or stock to loosen the sauce. Chicken & mushroom Hotpot actually improves overnight as the flavors keep talking to each other, so doubling the recipe and packing tomorrow's lunch is a high-leverage weeknight move.
