Save The oven door was fogged with steam, and I could hear the cream bubbling through the cracks around the foil. I was making this pie on a Sunday afternoon when nothing else seemed to matter except getting the layers right and keeping the potatoes from browning too fast. The kitchen smelled like butter and nutmeg, and I remember thinking it was the kind of smell that makes you forget you were supposed to be doing something else. My flatmate walked in, looked at the dish, and said it smelled like a pub in the countryside. I took that as a compliment.
I made this for a group of friends who were tired of pasta bakes and wanted something that felt like effort but didnt actually require it. We ate it straight from the dish with a bowl of dressed leaves on the side, and someone said it tasted like a gratin had married a pie and decided to stay in Britain. The top was crisp and golden, the middle was molten, and I learned that night that you can never have too much cheese when youre feeding people who showed up on time.
Ingredients
- Floury potatoes: Maris Piper or Yukon Gold break down just enough to soak up the cream without turning to mush, and slicing them thin helps them cook evenly without drying out.
- Onions and garlic: Sweating them in butter until theyre soft and translucent brings out their natural sweetness and keeps them from tasting raw in the finished pie.
- Gruyère cheese: This adds a nutty, slightly sweet depth that cheddar alone cant quite deliver, and it melts beautifully without splitting.
- Mature cheddar: The sharpness cuts through the cream and balances the richness, plus it gives you that familiar comforting flavor.
- Double cream and whole milk: The cream makes it indulgent, and the milk thins it just enough so it seeps between the layers instead of sitting on top.
- Dijon mustard: A teaspoon might seem small, but it sharpens the whole dish and keeps the dairy from feeling too heavy.
- Nutmeg: Freshly grated nutmeg smells like winter and adds warmth without announcing itself.
- Butter: Used to cook the onions and grease the dish, it also adds a little extra richness to the base layer.
- Chives: Optional, but they add a fresh green note that makes the final dish look less beige and more alive.
Instructions
- Prepare your dish and oven:
- Preheat the oven to 190°C (375°F) and generously butter a 2-liter ovenproof dish so the bottom layer doesnt stick. This also helps the edges crisp up nicely.
- Cook the onions and garlic:
- Melt the butter in a large saucepan over medium heat, then add the onions and garlic and cook for 6 to 8 minutes until theyre soft and translucent but not browned. Remove from heat and set aside.
- Mix the cream base:
- In a bowl, whisk together the double cream, milk, Dijon mustard, nutmeg, salt, and pepper until smooth. This mixture will seep into every layer as it bakes.
- Build the first layer:
- Arrange half the potato slices in the bottom of the dish, overlapping them slightly, then scatter half the onion mixture on top and sprinkle with half the Gruyère and cheddar. Press down gently so everything settles.
- Add the second layer:
- Repeat with the remaining potatoes, onions, and cheeses, making sure the top layer of potatoes is as even as possible. Pour the cream mixture evenly over everything and press down gently with a spatula to compact the layers.
- Bake covered, then uncovered:
- Cover the dish tightly with foil and bake for 40 minutes, then remove the foil and bake for another 20 minutes until the top is golden and bubbling. The foil traps steam at first, which cooks the potatoes through without drying them out.
- Rest and serve:
- Let the pie rest for 10 minutes before serving so the layers settle and the cream thickens slightly. Garnish with chopped chives if you like a bit of color.
Save This pie became the thing I made when I wanted to feel like I knew what I was doing in the kitchen, even when I didnt. It impressed people without requiring technique I didnt have, and it tasted like something youd order in a cozy restaurant with candles on the tables. I served it to my parents once, and my mum asked for the recipe, which is how I knew it had earned a place in the rotation.
Choosing Your Potatoes
Floury potatoes like Maris Piper or Yukon Gold are essential here because they absorb the cream and break down just enough to create a tender, cohesive layer. Waxy potatoes stay too firm and the pie ends up feeling more like a salad than a bake. I learned this the hard way when I used new potatoes once and ended up with something that looked right but ate wrong. If youre unsure, go for a baking potato and youll be safe.
Making It Ahead
You can assemble the entire pie up to a day in advance, cover it tightly with cling film, and keep it in the fridge until youre ready to bake. Just add an extra 10 minutes to the covered baking time if youre putting it in cold. I do this often when I know Ill be busy later, and it takes all the stress out of timing. The flavors also meld together overnight, which some people swear makes it even better.
Serving and Pairing
This pie is rich enough to stand on its own, but it loves a crisp green salad dressed with something sharp like lemon or vinegar to cut through the cream. Ive also served it alongside roasted vegetables or steamed greens, and it works beautifully as part of a larger spread. Leftovers reheat well in the oven, though they rarely last long enough to find out.
- Let it cool completely before covering and refrigerating, or condensation will make the top soggy.
- Reheat individual portions in the oven at 180°C for 15 minutes rather than microwaving, which can make the texture rubbery.
- If youre serving this to guests, consider baking it in a pretty dish you can bring straight to the table.
Save This is the kind of pie that makes people lean back in their chairs and sigh, and thats exactly what you want from a dish that takes less than two hours from start to finish. Make it once, and youll understand why its worth keeping in your repertoire.
Recipe Help & Answers
- → Can I prepare this dish ahead of time?
Yes, you can assemble the pie completely, cover it with foil, and refrigerate for up to 24 hours before baking. Add an extra 10 minutes to the covered baking time if cooking from cold.
- → What type of potatoes work best?
Floury potatoes like Maris Piper, Yukon Gold, or Russets are ideal as they become tender and creamy during baking while absorbing the flavors of the cream and cheese.
- → Can I substitute the cheeses?
Absolutely. While Gruyère and cheddar create a wonderful flavor, you can use Emmental, Swiss, Comté, or even a strong Lancashire cheese for different taste profiles.
- → How do I know when the pie is fully cooked?
The potatoes should be completely tender when pierced with a knife, the top should be golden brown and bubbling, and the cream mixture should be mostly absorbed with a slight sauce remaining.
- → Can I make this dairy-free?
You can substitute with plant-based cream, milk, butter, and dairy-free cheese alternatives, though the texture and flavor will differ from the traditional version.
- → What can I serve alongside this pie?
A crisp green salad with a tangy vinaigrette, steamed green beans, roasted vegetables, or wilted spinach complement the richness beautifully and add freshness to the meal.
