What is Potato Gratin?
Potato gratin, also known as gratin dauphinois, is a traditional French dish made by layering thinly sliced potatoes with cream, cheese, and seasonings, then baking it until golden and bubbling. In the UK, it’s a favourite comfort food served with hearty main dishes or as a rich vegetarian option.
Ingredients for Potato Gratin
To make potato gratin, you’ll need:
For the Dish:
- 1kg (2.2 lbs) of waxy potatoes (Maris Piper or Charlotte)
- 300ml double cream
- 300ml whole milk
- 2 garlic cloves, minced
- 1 tsp salt
- ½ tsp black pepper
- 1 tsp fresh thyme leaves (optional)
- 100g grated Gruyère cheese (or mature cheddar)
For Topping (Optional):
- 50g grated Parmesan
- 25g breadcrumbs
How to Make Potato Gratin
Step 1: Prepare the Potatoes
- Peel and Slice:
- Peel the potatoes and slice them thinly, about 3-4mm thick, using a mandoline or a sharp knife.
- Rinse and Dry:
- Rinse the potato slices under cold water to remove excess starch, then pat them dry with a clean towel.
Step 2: Prepare the Cream Mixture
- Heat the Cream and Milk:
- In a saucepan, combine double cream, milk, garlic, salt, pepper, and thyme. Heat gently until warm, but do not boil.
- Taste and Adjust:
- Adjust the seasoning to your preference.
Step 3: Layer the Potatoes
- Grease the Dish:
- Grease a medium-sized baking dish with butter or oil.
- Layer the Potatoes:
- Arrange a layer of potato slices in the dish, slightly overlapping. Pour a little cream mixture over the layer and sprinkle with grated Gruyère.
- Repeat:
- Continue layering until all potatoes and cream are used, finishing with a layer of cheese on top.
Step 4: Bake the Gratin
- Preheat the Oven:
- Preheat your oven to 180°C (160°C fan) or Gas Mark 4.
- Bake:
- Cover the dish with foil and bake for 45 minutes. Remove the foil and bake for an additional 20-25 minutes, or until the top is golden and the potatoes are tender when pierced with a knife.
Tips for the Perfect Potato Gratin
- Choose the Right Potatoes:
- Waxy varieties like Maris Piper or Charlotte hold their shape and create the best texture.
- Slice Evenly:
- Uniform slices ensure even cooking.
- Avoid Boiling Cream:
- Heating the cream mixture gently prevents it from curdling.
- Rest Before Serving:
- Let the gratin rest for 5-10 minutes after baking to set and intensify the flavours.
- Experiment with Cheese:
- Try combinations of Gruyère, cheddar, Parmesan, or blue cheese for different flavour profiles.
