Au Gratin Potatoes vs Scalloped Potatoes
For those who’re pondering, Wait, how are these au gratin potatoes completely different from scalloped potatoes?, it’s a very good query. The 2 dishes are each creamy potato casseroles, in spite of everything. Historically, the distinction comes right down to cheese. Au gratin potatoes all the time have cheese, whereas scalloped potatoes typically don’t.
Nevertheless, I do use cheese in my scalloped potatoes (a household custom!), so different variations set my recipes aside. These au gratin potatoes characteristic a richer sauce made with heavy cream and no roux, plus the next ratio of cheese to potato. I took some inspiration from the French dish potatoes dauphinoise in creating this recipe, utilizing the cream and Gruyère cheese for delectably wealthy taste. It’s a easy, but elevated, aspect dish for a vacation meal.
Finest Potatoes for Au Gratin
I feel russet potatoes are finest for potatoes au gratin. Their excessive starch content material helps thicken the sauce, and as they take up the cream within the oven, they turn into extremely tender. I like that tender texture with the creamy sauce and cheese right here. Slicing them thinly (I take advantage of a mandoline for this) helps them prepare dinner evenly and absolutely within the bake time.
How you can Make Au Gratin Potatoes
One factor I like about this au gratin potatoes recipe is how straightforward it’s to assemble. When you thinly slice the potatoes and onions and grate the cheese, it has 4 major steps:
1. Whisk collectively the cream sauce. No cooking required! Simply mix the cream, garlic, Dijon mustard, salt, and pepper in a bowl. Due to the cream’s fats content material, it doesn’t want a roux to thicken it.
2. Layer up the gratin. Prepare a 3rd of the potatoes in a greased 2-quart baking dish. High with half the onions, a 3rd of the cream combination, and a 3rd of the shredded cheddar and/or Gruyère cheese. Repeat these layers, then high with the remaining potatoes and cream. Cowl with foil.
3. Bake, lined, at 400°F till the potatoes are tender. This preliminary bake will take 1 hour to 1 hour and quarter-hour.
4. Add the remaining cheese and broil to brown the highest. The gratin is prepared when the cream is effervescent and the potatoes are browned across the edges.
Tip: Earlier than serving, let the potatoes stand at room temperature for 20 minutes. This may give the sauce time to arrange barely. (The potatoes are additionally blazing sizzling once they come out of the oven!)
How you can Retailer and Reheat
I discover that these potatoes are surprisingly good leftover. Retailer them in an hermetic container within the fridge for as much as 3 days. They’re barely much less creamy after sitting within the fridge, however the taste remains to be unbelievable. Reheat them within the microwave or in a lined dish in a 350°F oven.
I don’t suggest freezing them. The cheese and potatoes have a grainy texture once they thaw.
