Classic dauphinoise potatoes baked in a creamy garlic sauce and finished with Gruyere cheese. A rich and indulgent side dish that totally hits the spot!
I can totally eat this for dinner with nothing else.
Yes it makes a beautifully indulgent side dish with steak or salmon or roast lamb, but a double helping of this glorious dish, eaten whilst sat on the sofa in my PJs?
Heaven.
What are dauphinoise potatoes and how does this dish differ from potato gratin or boulangere potatoes?
Dauphinoise potatoes are thinly sliced potatoes cooked in the oven in a dish with cream and/or milk with a hint of garlic. It can be made with or without cheese. The potatoes are often layered in the dish raw. I prefer to pre-cook my potatoes in the milk and cream as this helps to thicken the sauce and prevent it from curdling.
Potato Gratin is often a term used interchangeably with dauphinoise potatoes. Any baked dish of thinly sliced vegetables cooked with cheese and butter is generally a gratin. Potato gratin can be made with a creamy sauce, sometimes with the inclusion of onions, garlic and/or breadcrumbs.
Boulangere potatoes are thinly sliced potatoes cooked in the oven in a dish with thinly sliced onions, stock, herbs (thyme, rosemary or sage) and butter.
What do we need?
Steps to make it
(Full ingredients and recipe instructions in recipe card below)
- Bring cream, milk and garlic to boil in a large saucepan,
- Peel and thinly slice potatoes (you can use a mandolin or the slicing attachment on a food processor). Add the potatoes to the heated cream mixture.
- Simmer for 6-7 mins, stirring occasionally until the potatoes are tender.
- Scoop half of the potatoes out of the pan and arrange them in the baking dish.Sprinkle over a little salt, pepper, nutmeg and grated Gruyere cheese.
- Spoon on the remaining potatoes, pour on some of the sauce, season once more and sprinkle on more Gruyere cheese.
- Place in the oven and bake for 40-45 minutes, until the cheese is golden.
Season with a little parsley before serving.
Why to I need to par-boil the potatoes first?
- Parboiling the potatoes helps to ensure the potatoes will be fully cooked and tender after 40-45 minutes in the oven. Using raw potatoes would increase the cooking time substantially, meaning the cheese could be too brown by the time the potatoes are tender.
- As the potatoes are parboiling in the cream and milk, they release starch into the sauce. This helps to:
- Thicken the sauce
- Ensure the sauce doesn’t curdle when the assembled dish is baked in the oven
Pro-tips:
- Peel the potatoes, then use the slicing attachment on a food processor to slice the potatoes thinly and quickly.
A mandolin is a good alternative to consistently slice the potatoes, although it will take longer. - When par-boiling the potatoes in the sauce, use a blunt knife to separate the layers of potato. The starch in the potatoes means the potato slices will try to stick together without having any sauce in between them. Stuck together potato slices is comparable to not slicing the potatoes at all, and it means the potatoes won’t cook evenly. Separate them out in the pan and ensure all of the slices get coated in the sauce and you’ll have perfectly tender, creamy potatoes.
- Don’t worry about arranging the potatoes neatly in the baking dish. So long as they’re fairly flat on top, they’ll cook evenly and you’ll still see those lovely layers when you cut into the dauphinoise.
What to serve with dauphinoise potatoes
Although very rich itself, I think dauphinoise potatoes works really well with rich meats such as roast lamb, steak or beef shortribs. However, it will also go perfectly with baked salmon (you could add a little lemon zest to the salmon to cut through the creaminess of the potatoes).
How about roast leg of lamb, slow-roast shoulder of lamb or rack of lamb.
You could also serve it as part of a roast pork, roast beef or roast chicken dinner
Serve along with:
- Green Beans with Garlic and Parmesan
- Simple Butter Pepper Carrotsor
- Baked Parmesan Sprouts with Bacon

Dauphinoise Potatoes
By Nicky Corbishley
Classic dauphinoise potatoes baked in a creamy garlic sauce and finished with Gruyere cheese. A rich and indulgent side dish.
Prep Time:
20 minutes mins
Cook Time:
50 minutes mins
Total Time:
1 hour hr 10 minutes mins
Servings: 8
Course: Dinner
Cuisine: French
Ingredients
- 480 ml (2 cups) double (heavy) cream
- 480 ml (2 cups) full-fat milk
- 3 garlic cloves peeled and lightly crushed (so they’re flatter, but stay in one piece)
- 1.25 kg (2.75 lbs) King Edward or Maris Piper potatoes use medium-sized potatoes
- ½ tsp salt
- ½ tsp black pepper
- pinch nutmeg
- ¼ tsp white pepper
- 150 g (1 1/2 cups) grated gruyere cheese
- 2 tbsp freshly chopped parsley
Instructions
Preheat the oven to 190C/375F (fan).
Lightly grease a large, shallow ovenproof dish. I use a 32cmx18cm dish (see *note 1 for conversion).
Place the cream, milk, and garlic into a large saucepan and bring to the boil, then turn down the heat.
480 ml (2 cups) double (heavy) cream, 480 ml (2 cups) full-fat milk, 3 garlic cloves
Peel the potatoes and slice thinly using the slicing attachment on your food processor or a mandolin. They need to be around 2mm thick.
1.25 kg (2.75 lbs) King Edward or Maris Piper potatoes
Add the potatoes to the cream and stir to coat.
Bring back to the boil, then simmer gently for 6-7 mins, stirring occasionally (to ensure the sauce doesn't catch on the bottom of the pan) until the potatoes are tender and just cooked. Don’t worry if they break apart a little.
While the potatoes are cooking, mix together the salt, black pepper, nutmeg, and white pepper in a small dish.
½ tsp salt, ½ tsp black pepper, pinch nutmeg, 1/4 tsp white pepper
Scoop half of the potatoes out of the pan and arrange them in the baking dish, being sure to separate any potatoes that have stuck together. Discard the garlic.
Sprinkle over half of the salt/pepper/nutmeg mixture and 1/3 of the gruyere cheese.
150 g (1 1/2 cups) grated gruyere cheese
Spoon on the remaining potatoes and pour over enough sauce so the potatoes are coated in sauce, but not drowning in it. The sauce should be quite thick, so there won't be much left in the pan anyway.
Sprinkle on the remaining seasoning and the remaining cheese.
Place in the oven and bake for 40-45 minutes, until the cheese is golden.
Top with fresh parsley before serving
2 tbsp freshly chopped parsley

Notes
Note 1
I use a 32cmx18cm (12.5"x 7") dish, but you could use a 24cmx24cm (9.4"x9.4") dish or 26cm/10" (ish) diameter round dish or even a cast iron skillet. Don't worry if your tin is a little smaller or a little bigger. Try to ensure it's at least 5cm (2.5") deep though.
Best potatoes for dauphinoise potatoes
Starchy/floury potatoes are the best option - as the starch in them helps to create a thicker sauce. Maris Piper, King Edwards, Rooster, Russets, Yukon golds and Desirée are all good options.
Can I make it ahead?
Yes, cook as per the recipe, but just place in the oven for 20 minutes rather than 40-45. Then you can cool, cover and refrigerate.
Remove from the refrigerator an hour before you want to reheat it (to take the chill off the centre) and cover in foil. Place in the oven at 190C/375F for 30-35 minutes, removing the foil for the last 15 minutes, until piping hot throughout.
Gruyere cheese
I like to use Gruyere cheese for dauphinoise for its delicate nutty flavour. You can swap it out for mozzarella or cheddar if you prefer.
