Secrets to the perfect gratin dishes: Essential utensils and techniques

Any cheese lover perks up at the mention of the word “gratin.” And rightly so - how could you possibly remain indifferent to a dish freshly taken out of the oven, covered in a golden crust of melted cheese?

But did you know that you don't necessarily need cheese to make a gratin dish? In fact, many French cookbooks only list two ingredients for the crust of au gratin recipes: butter and breadcrumbs.

Find out in our article how to make a classic gratin and which dishes you can perfect with this culinary technique that anyone can master.

What is gratin and why is it important?

Secrets to Perfect Gratin: Essential Utensils and Techniques

"Au gratin" is a French culinary term that refers to a dish covered with a browned crust, usually made of cheese, cheese and cream, breadcrumbs, breadcrumbs and butter or other similar combinations. The term comes from the French word "gratter," which means "to grate."

Gratin dishes are sometimes covered in a velvety sauce made with cream or milk. The delicious crust on top prevents the dish from drying out in the oven and gives it a divine flavour and a stunning appearance.

Many gratin recipes are easy to prepare and can be made ahead of time. Just before serving, sprinkle with your favorite cheese mixed with crispy breadcrumbs on top and pop them in the oven. As the inside heats up, the outside develops an irresistible crust.

The best gratin dishes

Pasta au gratin is becoming increasily popular in kitchens because it is filling, easy to make and loved by children and adults alike.

After all, even vegetables suddenly become more appetizing when you top them with a mixture of sour cream and cheese. For vegetables gratins, we recommend using cauliflower, broccoli, sweet potatoes, Brussels sprouts or eggplant and zucchini stuffed with meat, vegetables or couscous.

However, the champions of vegetable gratins remain potatoes. A very popular recipe in Romania is French fries, so tasty and rich in cheese, cream and butter.

Moussaka is also loved throughout the country, whether you prepare it with sliced potatoes or mashed potatoes.

How to choose the right utensils for gratin?

As sophisticated and appetizing as gratin dishes may look, they are just as simple and accessible to make. Gratin techniques do not require any special tools – other than an appropiate baking dish.

What is the best cookware for making a gratin?

You can use a rectangular dish, like these roast pans. The roast pan does not have to be too deep and it is ideal if it has handles so you can easily take it out of the oven when it's hot, like this gratin dish.

You can also make gratin dishes in individual servings, using ramekins and small dishes for soufflés and gratins.

Cast iron and ceramic dishes are ideal for making a gratin as they retain heat and ensure even baking.

Another popular and suitable option for gratin puddings is Pyrex heat-resistant glass dishes.

Essential techniques for making a perfect gratin

Evenly slicing vegetables

For vegetables gratins, the slices should be approximately the same thickness to cook at the same time. We recommend using a mandolin, which can help you get very thin slices.

Proper layering

Use vegetables with similar cooking times. For example: potatoes with carrots or other root vegetables, broccoli with cauliflower, zucchini with bell peppers and eggplant.

Arrange the vegetable slices so that they partially overlap and are tilted at an angle of about 45°. This ensures that the cream sauce will seep through all the vegetables.

Using sauces

For a richer, creamier dish, use a sour cream sauce or a béchamel sauce that you pour over the vegetables while still warm. This will warm the ingredients and shorten the cooking time.

While heating the sauce, you can give it a more intense flavour by using garlic, nutmeg, thyme, sage, or bay leaves.

Temperature control and baking time

Generally, gratin dishes should not be baked at a temperature higher than 200°C, but it is best to follow the recipe's instructions.

Start by baking the dish without the cheese topping until the ingredients begin to soften. About 10-15 minutes before the dish is ready, sprinkle cheese or breadcrumbs with butter on top. This ensures you get a crispy crust without burning it.

5 secrets for getting a perfect crust

Choose cheese that melt nicely and brown well, such as Parmesan or Grana Padano, cheddar, hard cheese, Gruyere cheese.
Avoid pre-grated cheeses that may contain starch and grate fresh cheese yourself for a much finer and more flavorful crust.
For a crispier topping, mix breadcrumbs with melted butter or olive oil and sprinkle them over the grated cheese.
When the dish is ready, sprinkle parsley, green onions or chives on top for extra flavor and a perfect presentation.
Let the gratin dish rest for 10 minutes after taking it out of the oven, so that the topping sets and the dish can be easily cut without falling apart.

Now that you know the secrets to a perfect gratin, all that's left is to find the recipes that inspire you. Happy cooking!
