Mary Berry Shepherd’s Pie Dauphinoise Recipe

If you love a classic shepherd’s pie but want something a little more special than mashed potato, this version with a dauphinoise topping is the one to try. You get a rich, savoury lamb filling underneath layers of thinly sliced potatoes baked in cream until tender, glossy, and beautifully golden on top. It is comfortably doable for a confident beginner, just take your time with the slicing and layering. Set aside about 1 hour 40 minutes from start to serving, including a short rest so it slices neatly

How to Make Mary Berry Shepherd’s Pie Dauphinoise Recipe

Prepare the oven: Preheat the oven to 200°C or 180°C fan. Place a shelf in the middle of the oven so the pie cooks evenly and the topping colours nicely.
Grease your dish: Lightly butter a deep baking dish (about 20 x 30cm, or similar). This helps with serving and stops any sticky edges.
Soften the vegetables: Heat the olive oil in a large frying pan over medium heat. Add the onion, carrots, and celery (if using) with a pinch of salt. Cook for 8 to 10 minutes until softened and starting to turn sweet.
Brown the lamb: Add the crushed garlic and cook for 30 seconds, then add the lamb mince. Turn the heat up slightly and cook for 6 to 8 minutes, breaking it up with a spoon, until no longer pink and lightly browned.
Build the gravy: Stir in the tomato purée and cook for 1 minute. Sprinkle over the flour and stir well so it coats the mince. Pour in the red wine (if using) and let it bubble for 1 to 2 minutes, scraping up any flavour from the bottom of the pan.
Simmer until rich: Add the hot stock, Worcestershire sauce, and rosemary. Bring to a gentle simmer and cook for 15 to 20 minutes, stirring now and then, until thick and spoonable. Stir in the peas for the final 2 minutes, then taste and season well with salt and pepper.
Spoon in the filling: Tip the lamb mixture into your prepared baking dish and level it out. Set aside while you prepare the topping.
Warm the cream mixture: In a saucepan, add the double cream, milk, butter, grated garlic, nutmeg (if using), and a good pinch of salt and pepper. Warm gently until the butter melts and the mixture is hot but not boiling.
Slice the potatoes: Slice the peeled potatoes thinly (about 2 to 3mm). A mandoline makes this quick, but a sharp knife works fine. Try to keep the slices even so they cook at the same speed.
Coat the potatoes: Add the potato slices to the warm cream mixture and gently stir so every slice is coated. This helps stop the potatoes from discolouring and starts the cooking process.
Layer the topping: Arrange the potato slices over the lamb filling in neat, overlapping layers. Pour over any remaining cream mixture from the pan, then scatter the grated cheese evenly over the top (add thyme leaves if using).
Bake (covered, then uncovered): Cover the dish with foil and bake for 35 minutes. Remove the foil and bake for a further 25 to 30 minutes, or until the potatoes are tender when pierced with a knife and the top is deep golden and bubbling at the edges.
Cool briefly, then serve: Rest the pie for 10 to 15 minutes before serving. This gives the filling time to settle so you can slice and lift out tidy portions.

Tips for Best Results

How do I stop the dauphinoise topping from staying firm in the middle?

Slice the potatoes evenly and thinly, then cover with foil for the first part of baking. If the top is browning but the middle still feels firm, pop the foil back on and give it another 10 minutes.

Why is my filling watery?

The filling should be thick before it goes into the dish. Simmer until it holds its shape on a spoon, and do not skip the flour. If you add extra stock, let it reduce properly before assembling.

Can I make it ahead without the potatoes going grey?

Yes. Keep the sliced potatoes submerged in the warm cream mixture so air cannot reach them. Assemble, cool, cover, and refrigerate. Bake the next day, adding 10 minutes covered if it is going in cold.

How do I get a properly golden top without drying the potatoes?

Cheese helps with colour, but the key is uncovering at the end and baking until bubbling. If you want extra colour, grill for 2 to 3 minutes at the very end, watching closely.

Serving Suggestions

Buttered cabbage or spring greens with a squeeze of lemon
Honey-glazed carrots or roasted parsnips
A simple green salad with a sharp mustard dressing
Extra gravy on the side for spooning over

Storage

Room temperature

Let the pie cool, then keep it out for up to 2 hours before refrigerating. Because it contains meat and dairy, it is not one to leave on the counter all afternoon.

Refrigerator

Store covered in the fridge for up to 3 days. Reheat in a 180°C (160°C fan) oven until piping hot throughout, about 25 to 35 minutes depending on portion size. Cover loosely with foil if the top is getting too dark.

Freezing

Freeze well-wrapped portions for up to 3 months. Thaw overnight in the fridge, then reheat in the oven until hot all the way through. The potatoes can soften slightly after freezing, but the flavour stays lovely.

FAQs

What is the best potato for a dauphinoise topping on shepherd’s pie?

Floury potatoes like Maris Piper or King Edward work beautifully here because they turn tender and creamy in the hot cream mixture. If you use a waxier potato, it can take longer to soften, so keep slices very thin and expect extra baking time.

Can I use beef mince instead of lamb?

Yes. If you use beef mince it becomes closer to a cottage pie, but the method stays the same. Beef stock works especially well, and a little extra Worcestershire sauce is lovely with beef.

Do I have to add cheese on top?

No, it is optional. Cheese gives a golden finish and a slightly savoury crust, but the dauphinoise will still brown without it. If skipping, brush the top lightly with melted butter for colour.

Can I assemble it the day before and bake later?

Yes. Assemble the pie fully, cool, cover, and refrigerate for up to 24 hours. Bake as directed, adding about 10 minutes to the covered baking time to make sure the centre heats through and the potatoes soften properly.

Why did my dauphinoise split and look oily?

This usually happens if the cream mixture boils hard. Warm it gently, keep the oven temperature as stated, and cover for the first part of baking. A steady bake gives a smoother, creamier finish.
