Shredded Chicken and Vegetable Pie with Dijon Mustard Roux Recipe

 

Shredded‑chicken pie with seasonal veg and a flaky pastry lid - perfect for the first cold nights.

Chicken Pie for the First Cold Nights

There’s a moment each year when the evenings cool and the light fades earlier, and the kitchen becomes the place we drift back to. It’s the season for simple, thrifty comfort - the kind of cooking that stretches a single chicken breast into something generous. A pie like this fits right in: the last of seasonal summer New Zealand vegetables in a creamy white sauce Dijon mustard roux filling you can make ahead, and a flaky pastry top that turns golden in the oven while the house fills with warm, comforting aromas.

Making chicken go further

Starting with a chicken breast is both economical and practical as there's no waste. A gentle poach for a few minutes with bay leaves gives you tender meat and a light poaching liquid to use in the roux and freeze the remainder for another dish. Once it has cooled, the chicken pulls apart easily with two forks. Shredding it means every strand gets coated in sauce later, and the meat goes much further (see short tutorial below for technique).

This is also the moment to use whatever vegetables are in season or lingering in the crisper. Carrots, leeks, waxy potatoes, spinach, courgette (zucchini) mushrooms - they all soften into the filling and bring their own quiet sweetness.

A Dijon roux that brings it together

Sprinkling the flour and instant chicken stock over the vegetables and mixing gently means the butter absorbs it, helping the roux come together smoothly without lumps.

The base of the pie is a simple thick white sauce roux: butter melted until it smells warm and nutty, finely chopped onion and crushed garlic sautéed, then the shredded chicken and vegetables folded into cook gently. Sprinkling the flour and instant chicken stock over the vegetables and mixing gently means the butter absorbs it, helping the roux come together smoothly without lumps. Next comes a splash of milk and some of the poaching water, along with the Dijon mustard to give the sauce a gentle lift — not sharp, just enough to deepen the roux. A little cream rounds it out if you have some open.

Under a flaky pastry lid (or a potato alternative)

A pie like this doesn’t need much more than a good flaky pastry top. Homemade or store‑bought both work; the magic is in the contrast between the crisp lid and the thick, cosy yet creamy filling underneath. As it bakes, the pastry puffs and browns, and the kitchen fills with the smell of butter, vegetables, and slow‑cooked chicken. If pastry isn’t on hand, mashed potato or thick slices of cooked potato make a hearty alternative and turn it into more of a cottage‑style pie.

It’s the sort of dinner that fogs the windows slightly and has people drifting into the kitchen to ask how long until it’s ready. A proper comfort dish for the first cold nights — warm, thrifty, and deeply satisfying.

Making it ahead for an easy week-night bake

Once the filling is made, it keeps well in the fridge, which makes this pie even easier on a busy evening. Having it ready to go means all you need to do is spoon it into a dish, lay the pastry over the top, and slide it into the oven. The heat does the rest — the pastry rises, the edges bubble, and before long the kitchen smells like you’ve been cooking for hours. It’s the kind of make‑ahead comfort that suits these first cold nights perfectly.





Ingredients:

(serves 2, double for 4)

  • 250-300 gm boneless chicken breast
  • 1-2 bay leaves
  • Water
  • 1 onion, peeled and finely chopped
  • 1 tsp crushed garlic
  • 50gm butter
  • 1/2 - 3/4 cup milk
  • 1-2 medium courgette (zucchini)
  • 3-4 florets of broccoli, broken into small pieces
  • 2 medium carrots, peeled and cut into small chunks
  • 2 waxy potatoes, cubed (peeled or unpeeled)
  • Handful of green beans cut into small pieces
  • 2-3 tablespoons plain flour
  • 1 generous tsp French Dijon Mustard
  • Ground salt and black pepper

Method:

Poach the chicken breast with the bay leaves in a small pot, using just enough water to cover the meat. Simmer gently for 10–15 minutes. While it cooks, prepare the rest of the ingredients.

Set your flaky pastry sheet on the bench to defrost.

Sauté the onion and garlic in a large pot over low heat. Add the potato, carrot, and courgette and cook for a few minutes.

Sprinkle over the flour and instant chicken stock, stirring so the vegetables are coated.

Remove the bay leaves from the poaching liquid, lift the chicken onto a board, and shred it with two forks (see the tutorial video above for a quick 'how‑to'). Reserve the poaching liquid.

Add the remaining vegetables and the shredded chicken to the pot, along with a few grinds of salt and pepper, the Dijon mustard, milk, and a splash of the chicken poaching liquid. Stir gently for a few minutes until the roux thickens and coats everything. The vegetables should still be firm and colourful and the mixture thick rather than runny; if it’s too loose, a little cornflour will bring it together.

Place your baking dish upside down on the pastry sheet and trace around it, leaving a couple of centimetres extra so you can create a decorative edge.

Spoon the filling into the baking dish, lay the pastry on top, and fold or crimp the edges - even a simple fold-over pressed with a fork looks lovely.

Brush with an egg or milk wash for a golden crust.

Bake at 200°C for 30–45 minutes, until the pastry is golden.

Et voilà.
