Ingredient Breakdown
The key ingredients in this recipe are the potatoes, garlic, rosemary, and cheese. The potatoes should be high-starch potatoes, such as Russet or Idaho, as they will yield a creamy and tender texture. The garlic should be fresh and of high quality, as it will add a depth of flavor to the dish. The rosemary should be fresh and fragrant, as it will add a piney and herbaceous flavor to the dish. Finally, the cheese should be a combination of grated cheddar and Parmesan, as it will add a rich and creamy texture to the dish. When selecting these ingredients, be sure to choose the best quality you can find, as it will make a big difference in the final dish.
How to Make creamy garlic potato and rosemary gratin for cold winter nights
Preheat the oven to 375°F (190°C). This will ensure that the gratin cooks evenly and at the right temperature.
Peel and thinly slice the potatoes. This will help them cook evenly and quickly.
Melt the butter in a saucepan over medium heat. Add the garlic and cook until fragrant, about 1 minute. Then, add the flour and cook for 1 minute, stirring constantly. Finally, add the milk and cook until the sauce thickens, about 2-3 minutes.
In a greased 9x13-inch baking dish, create a layer of potatoes. Then, add a layer of garlic sauce, followed by a layer of cheese. Repeat this process until all the ingredients are used up, finishing with a layer of cheese on top.
Bake the gratin in the preheated oven for 45-50 minutes, or until the top is golden brown and the potatoes are tender.
Let the gratin rest for 10-15 minutes before serving. This will allow the flavors to meld together and the cheese to set.

- 1 large egg, beaten
Instructions
- Preheat the oven. Preheat the oven to 375°F (190°C). Grease a 9x13-inch baking dish with butter and set it aside.

- Assemble the gratin. In the prepared baking dish, create a layer of potatoes. Top with a layer of the sautéed onion and garlic mixture, followed by a sprinkle of the remaining cheddar cheese and parmesan cheese. Repeat this process until all ingredients are used, finishing with a layer of cheese on top.
- Make the cream sauce. In a small bowl, whisk together the heavy cream and beaten egg. Pour the cream sauce over the top layer of cheese.
- Bake the gratin. Cover the baking dish with aluminum foil and bake for 30 minutes. Remove the foil and continue baking for an additional 15-20 minutes, until the top is golden brown and the potatoes are tender.
