Our favorite new side dish (or vegetarian main, if made with vegetable broth) is a colorful version of scalloped potatoes. For richest flavor and color, look for deep-orange-fleshed sweet potatoes with skin that's burnt orange to dark red. A food processor's shredding disc and 2-mm. slicing blade make quick work of the cheese, sweet potatoes, and shallot.

How to Make It

Step 1

Preheat oven to 375°. Evenly arrange half of sweet potatoes and shallot (including any uneven pieces) in a shallow 2 1/2- to 3-qt. baking dish. Combine chopped thyme, salt, and pepper in a small bowl, and gouda and 1 tbsp. flour in another bowl. Sprinkle sweet potatoes with half of thyme mixture and half of gouda mixture. Arrange remaining sweet potatoes in dish in overlapping rows. Scatter with remaining shallot and thyme mixture.

Step 2

In a small bowl, whisk remaining 3 tbsp. flour with 1/4 cup cream until smooth. Whisk in remaining cream and the broth. Pour evenly over sweet potatoes and top with remaining gouda mixture.

Step 3

Bake until gratin is bubbling and golden brown, 45 to 55 minutes, increasing the heat to 400° for the last 5 minutes or so. Let sit 10 minutes before serving. Set a thyme sprig on top and add more salt and pepper to taste.

Typo in the directions, otherwise delicious!

I tried making for thanksgiving, turned out delicious but I was worried it wouldn't. Following the recipe and there is a typo with the heavy cream in the directions. 3 tablespoons of flour and 1/4 cup of cream made a paste. I had to water down with another half a cup of cream as per listed at 3/4 cup in the ingredients list instead of 1/4 cup in the directions.

More better than you can imagine!

Easy to make (after you slice the sweet potato) plus it tastes even better the next day. Another benefit is that you don't get the full belly carb feeling after eating this like you would if it was made with regular potatoes.

Made for T-day, was perfect, not too heavy and very easy to make.  Made a perfect amount for 10 people with a bit leftover (that's with all the other t-day food - it went further).  Loved using the sweet taters vs. russets/golds as it just changes the flavor enough to make it special.  Making it for a pot-luck xmas party tomorrow night, will double as they're expecting around 20.  Oh, and this is a bit 'forgiving' since I actually didn't follow the recipe well and it still was wonderful.
