As you will notice while reading this recipe, I parboiled the potatoes. This process will help your potatoes cook faster and more evenly. You are not taking anything away from the flavor.
I have made and enjoyed this easy recipe for potato gratin with parboiled and raw potatoes. Although the latter took longer to cook, they both had the same fantastic flavor.

A few ingredients are needed to create this fantastic side dish.
Ingredients needed to make this recipe
This is a short introduction. The ingredient list is also brief. It includes essential items that you may already have in your pantry. Please read the recipe for complete instructions.
Potatoes – waxy potatoes are perfect for this dish. All the same size, so they will cook evenly. Peel and slice them into even rounds.
Gruyere cheese or mozzarella – gives that exceptional softness between layers of potatoes.
Heavy cream – once baked, the heavy cream turns into that amazing creamy sauce, tenderizing your potatoes.
Unsalted butter – always use unsalted butter. You want to have control of the seasoning, and salted butter will not only add too much salt to your dish but change its flavor.
Salt and black pepper – the seasoning that you will need. Be generous.

Step by step on how to make this delicious potato gratin
With all my recipes, please assemble all the ingredients before starting cooking and baking.
- Preheat the oven to 375 F.
- While the oven is warming, parboil your potatoes in a large pan covered with water and sea salt. Bring to a boil and check for doneness with the knife. You should have some resistance. Drain.
- Meanwhile, rub the butter all over the gratin dish, ensuring the whole surface is completely covered.
- Add half of your potatoes in the gratin dish,
- Sprinkle generously with salt and pepper and add the desired amount of cheese over it.
- Cover with the remainder of the potatoes, seasoning with salt and pepper.
- Distribute the heavy cream all over the top, place in the hot oven, and bake for around 30 minutes or until golden brown on the top.
Pro Tips
- Slice your potato slices evenly to ensure proper cooking.

Variations and Substitutions
You will find so many versions of this recipe, and those are the variations that I have made throughout the years:
- Crushed cloves of garlic rubbed on the casserole dish or gratin dish.
- I have also warmed up the heavy cream with the garlic cloves. I love it as the garlic oils enhance the cream flavor.
- Fresh thyme or bay leaf added to the cream mixture is another excellent combination.
- I do not recommend substituting the heavy cream. You do need that richness.

Storing and Reheating
Store: Cover tightly with plastic wrap or aluminum foil once your gratin is thoroughly cooled. Store in the refrigerator for up to two days.
Reheat: Bring your potatoes back to room temperature. Warm them in the oven at 350F for about 20 to 30 minutes. If they are dry, add more butter or cream.
