What Are Au Gratin Potatoes?
The potatoes used in au gratin are thinly cut potatoes that have been layered with cream, cheese and sometimes a little garlic or onion. They are then baked until they become tender and golden brown. Au gratin potatoes are richer than scalloped potato, which is usually made with cream. They also have a crispy top.
This dish is a staple of many kitchens all over the world. It originated in French cuisine, where gratin means simply a browned surface.
Ingredients You’ll Need
To make perfect au gratin potatoes, you’ll need to use whole, fresh ingredients. Here’s the list of ingredients you’ll need.
- Yukon gold or russet potatoes, 2 lbs.
- Two cups of half-and-half or heavy cream
- 2 cups shredded cheddar, Gruyere, or a cheese blend
- 2 tablespoons of unsalted butter
- 2 cloves garlic, minced
- Finely chop one small onion (optional, but recommended).
- Taste salt and pepper
- Fresh thyme (optional) or parsley for garnish
Step-By-Step Instructions
1. Prep and Preheat
Preheat your oven to 375°F. A medium-sized dish may be oiled with cooking spray or butter.
Peel and cut the potatoes into rounds that are about 1/8 inch thick. The mandoline is great for uniformly slicing the potatoes, which will ensure even cooking.
2. Creamy Base
Use a medium saucepan set over medium heat to melt the butter. Sauté the chopped onion and garlic for two to three minutes, or until they are aromatic and transparent. After adding the cream, come to a simmer. Season with salt and pepper to taste. Add about 1 1/2 cups and stir until the cheese melts. Take off the heat.
3. Layering the Potatoes
Spread half the potatoes evenly in the baking dish. Spread half of the sauce evenly over the potatoes. Repeat the process with the rest of your potatoes and cheese sauce. Add the remaining 1/2 cup of cheese to the final layer for a delicious crust.
4. Bake To Perfection
After lightly covering the dish with foil, bake it for forty minutes. After taking off the foil, bake the dish for a further twenty to twenty-five minutes, or until the top is bubbling and brown. Make sure the potatoes are fork-tender.
Allow the sauce to settle and thicken for at least 5-10 minutes prior to serving.
Tips To Make Perfect Au Gratin Potatoes
- Starchy Potatoes: Yukon Gold and Russet potatoes are the best for baking because they absorb cream well. They also bake up soft without becoming mushy.
- The Cheese You Choose Matters: Gruyere has a delicious nuttiness and melts well, while cheddar is tangy. Combining different cheeses creates a complex flavor.
- Do not skip the resting time: Resting the dish before serving will help it to firm up and slice cleanly.
- Optional crunch: For an added texture, sprinkle breadcrumbs mixed with melted butter and herb mixture over the top of the final baked product.
Serving Suggestions
The potatoes are a great accompaniment to roasted meats such as chicken, ham or beef tenderloin. Also, they complement vegetarian mains such as mushroom Wellingtons or grilled Portobello Steaks. To balance this, add a steamed or fresh green vegetable salad.
Why Boxed Beats Homemade
Even though pre-made or boxed au gratin mixes can be quick, the taste and texture are not as good as homemade. Making au gratin potatoes allows you to control all the flavor elements, from the velvety sauce to the crispy cheese topping. Impress your family or guests with your culinary abilities.
You can also easily customize this recipe. Add cooked bacon to add a smoky flavor, use plant-based cream instead of dairy for a dairy free version, or spice up the dish with cayenne pepper or smoked-paprika.
