Instructions to Make Mary Berry Leek And Potato Gratin
Follow these instructions to make Mary Berry’s leek and potato gratin:
Step 1: Preheat the oven and prepare the potatoes
- Preheat the oven to 200°C (180°C fan, gas mark 6) and lightly grease the ovenproof dish with some butter.
- Cut the potatoes into thin slices, about 3 mm (1/8 inch) thick. You can use a sharp knife, a mandoline, or a food processor to do this. Try to make the slices as even as possible, so they cook evenly.
- Rinse the potato slices under cold water and drain them well. Pat them dry with a kitchen towel and set them aside.
Step 2: Cook the leeks
- Cut the leeks into thin slices, about 1 cm (1/2 inch) thick. Rinse them well under cold water and drain them well. Pat them dry with a kitchen towel and set them aside.
- Melt the butter in a large frying pan over medium-high heat. Add the leeks and cook, stirring occasionally, for about 15 minutes, or until they are soft and lightly browned. Season with salt and pepper to taste.
Step 3: Layer the potatoes and leeks
- Arrange a layer of potato slices on the bottom of the prepared dish, slightly overlapping them. Sprinkle some salt and pepper over them.
- Spoon half of the leek mixture over the potatoes, spreading it evenly.
- Repeat with another layer of potatoes, salt, pepper, and the remaining leek mixture.
- Finish with a final layer of potatoes, salt, and pepper.
Step 4: Pour the stock and cream
- In a measuring jug, combine the chicken stock and the double cream. Stir well and pour the mixture over the potato and leek layers, making sure to cover them completely.
- Sprinkle the grated cheese over the top, covering the whole surface.
Step 5: Bake the gratin
- Place the dish on a baking sheet and bake in the preheated oven for 25 to 30 minutes, or until the cheese is bubbling and golden, and the potatoes are tender when pierced with a knife.

FAQs
Can I make Mary Berry’s Leek and Potato Gratin ahead of time?
Yes, you can prepare this gratin ahead of time. Assemble the dish without baking and cover it with foil or plastic wrap, then refrigerate. When you’re ready to serve, bake it as directed, adding an extra 5-10 minutes to the cooking time since it will be starting from a colder temperature. It’s a great way to manage time for dinner parties or busy weekdays.
How do I make the potatoes and leeks thin and even?
You can use a sharp knife, a mandoline, or a food processor to slice the potatoes and leeks. Try to make them about 3 mm (1/8 inch) thick for the potatoes and 1 cm (1/2 inch) thick for the leeks. Rinse and dry them well before layering them in the dish.
How do I prevent the cheese from burning?
You can cover the dish with foil for the first 15 minutes of baking, then remove the foil and bake for another 25 to 30 minutes, or until the cheese is golden and bubbly. You can also use a cheese that melts well and doesn’t brown too quickly, such as cheddar, gruyere, or parmesan.
Can I add other vegetables or proteins to the gratin?
Absolutely! While the classic leek and potato gratin is delightful on its own, it’s also versatile. Consider adding slices of carrot for sweetness or zucchini for a lighter touch. For proteins, cooked, crumbled bacon or diced ham can be added between layers for a savory twist. Just make sure to cook and season any additional ingredients before layering them into the gratin.
How do I make the gratin more creamy or less runny?
The amount of liquid in the gratin depends on the type and size of the potatoes, the amount of cream and stock, and the baking time and temperature. To make the gratin more creamy, you can use waxy potatoes, such as Yukon Gold, Charlotte, or Desiree, as they hold their shape better and don’t release too much starch. You can also reduce the amount of stock and increase the amount of cream, or bake the gratin for longer until the sauce thickens. To make the gratin less runny, you can use starchy potatoes, such as Maris Piper, Rooster, or King Edward, as they absorb more liquid and make the sauce thicker. You can also increase the amount of stock and reduce the amount of cream, or bake the gratin for shorter until the potatoes are tender.
What can I substitute for cream in the gratin to make it lighter?
If you’re looking to lighten up the dish, you can substitute the double cream with a lighter version like single cream or half-and-half. For a non-dairy alternative, unsweetened almond milk or oat cream can work, though the gratin might be less rich. Adjust thickness and seasoning as these substitutes might alter the consistency and flavor slightly.
