- 2 cups (480 ml) milk
- 1 cup (240 ml) heavy cream
- 2 teaspoons (10 g) salt
- 1/2 teaspoon black pepper
- 1 cup (100 g) grated Cheddar cheese
- 2-3 sprigs of fresh parsley for garnish
Ingredient Notes

Kitchen Tools Needed
- Baking dish (38×20 cm or similar)
- Peeler
- Sharp knife
- Cutting board
- Saucepan
- Whisk
- Measuring cups and spoons
Step-by-Step Instructions
- Preheat your oven to 220°C (425°F).
- Peel the potatoes and slice them into thin rounds, about 1/8 inch thick. Arrange the slices neatly in the baking dish.
- In a saucepan over medium heat, melt the butter. Stir in the flour and cook, stirring constantly, for 1-2 minutes until just golden.
- Gradually whisk in the milk, continuing to stir to avoid lumps. Once the mixture thickens, add in the cream, salt, and black pepper. Remove from heat after it’s smooth.
- Pour the béchamel sauce evenly over the arranged potatoes, making sure to cover them well.
- Cover the dish tightly with foil (you can line the foil with parchment paper to prevent sticking) and bake in the preheated oven for 45 minutes.
- After 45 minutes, take off the foil, sprinkle the grated Cheddar cheese on top, and return the dish to the oven for another 15 minutes or until the cheese is bubbling and golden.
- Once done, remove from the oven and let it cool slightly. Garnish with chopped parsley, slice, and serve hot. Enjoy every creamy bite!
Pro Tips
- For a deeper flavor, add minced garlic or thyme to the béchamel sauce.
- Ensure your potatoes are sliced evenly for uniform cooking.
- Let the gratin rest for a few minutes before serving; this will help it set and make slicing easier.
Common Mistakes
- Not overlapping the potato slices can lead to uneven cooking.
- Cooking the béchamel too long can create a lumpy texture.
- Skipping the resting time after baking might make the dish fall apart when slicing.
Variations
- Herb Gratin: Stir in fresh herbs like thyme or rosemary into the béchamel for added flavor.
- Mushroom Addition: Sauté sliced mushrooms and layer them with potatoes before pouring the sauce over.
- Spicy Kick: Add a pinch of cayenne pepper or some red pepper flakes to the béchamel for a bit of heat.
