Onion Potato Gratin Recipe

By RoketJSquerl

My father discovered this potato gratin recipe in Bon Appetit magazine and it has since become a family favorite. With cream, cheese, onions, and potatoes, how can one go wrong? Unless of course you are on a diet, in which case you should probably stay away from this one. This recipe is easy to make, delicious, and filling.

Ingredients

• 1 1/2 pounds Yukon Gold potatoes, peeled, cut into 1/4 inch thick slices
• 3/4 pound onions, thinly sliced
• 1 cup (packed) grated Gruyere cheese (about 4 oz)
• 8 Tbsp (packed) freshly grated Parmesan cheese (about 2 oz)
• 2/3 cup whipping cream

Preparation

Step 1

Preheat oven to 400°F (unless preparing in advance). 1 Combine Yukon Gold potatoes and sliced onions in heavy large saucepan. Add enough water to cover. Bring water to boil. Reduce heat and simmer until potatoes are almost tender, about 3 minutes. Drain potato onion mixture well. 2 Arrange half of potato-onion mixture in 11x7 inch glass baking dish. Sprinkle with salt and pepper. Sprinkle mixture with 1/3 cup Gruyere cheese and then 2 Tbsp of Parmesan cheese. 3 Arrange remaining potato-onion mixture atop cheeses. Pour cream over. Sprinkle with salt and pepper. Sprinkle the remaining 2/3 cup of Gruyere and 6 Tbsp of Parmesan cheese. (Can be prepared 8 hours in advance. Cover and refrigerate.) 4 Bake gratin uncovered in 400°F oven until cream thickens, about 25 minutes. Remove from oven. Preheat broiler. Broil gratin until top is golden, about 2 minutes.
