This hearty chicken and ham casserole is packed with tender vegetables, a savory cider-spiked broth, and fluffy mustard dumplings baked until golden. It is a comforting one-pan dinner that feels special enough for Sunday supper but is simple enough for a cozy weeknight meal.
Heat the sunflower oil and butter in a large ovenproof casserole over medium heat. Add the chopped onion, sliced leeks, chopped carrots, and a pinch of salt. Cook gently for about 10 minutes, stirring occasionally, until the vegetables are soft and translucent.
Add the chicken thighs and increase the heat slightly. Cook for 5 minutes, turning the pieces so they lightly brown on the outside. Pour in the cider and simmer for 3 minutes to cook off some of the alcohol.
Pour in the hot chicken stock and add the tied thyme. Bring the casserole to a gentle simmer, season with salt and pepper to taste, then cover and cook on low heat for 30 minutes, or until the chicken is tender.
Meanwhile, heat the oven to 180C/160C fan/gas 4. To make the dumplings, mix the self-raising flour, baking powder, mustard powder, suet or grated cold butter, chopped parsley, and 1/2 tsp salt in a bowl. Add 8-10 tbsp water a little at a time and bring the mixture together into a firm, slightly pliable dough. Divide into 8 equal pieces.
Remove and discard the thyme bundle from the casserole. Spoon a little of the hot cooking liquid into a small bowl, stir in the cornflour until smooth, then return the mixture to the pan. Stir in the shredded ham hock, peas, and mustard.
Arrange the dumplings on top of the casserole. Cover and bake for 30 minutes, then remove the lid and bake for 10 minutes more, until the dumplings are puffed and golden. Serve hot in deep bowls.
Dijon mustard gives a milder flavor, while English mustard makes the dumplings sharper and more robust. If ham hock is unavailable, use leftover cooked ham or gammon. The stew base can be cooled and frozen for up to 3 months; add freshly made dumplings when reheating for the best texture.
