Recipe Box, Sweet Potato Gratin

in our quest for Thanksgiving recipes this year HHjr and I are trying out some recipes in the current Southern Living Magazine, Thanksgiving Made Southern.  I recently posted Green Beans Clementine which were adapted from “Warm & Rustic Texas Thanksgiving,”  Green Beans with Citrus and Pecans.

Next we decided to try [he cooks, I photo] the Sweet Potato Gratin from the “Fresh and Modern Alabama Thanksgiving” section.  We didn’t change a thing and it was a big hit in my book.

The sweet potatoes give the standard scalloped potato dish a real flavor boost and cut the richness of the cream and cheese in a very palatable way.


Scalloped or Au gratin potatoes have a reputation of being hard to make, but if you stay true to two things they will be perfect every time.  Tip 1: Slice your potatoes evenly and very thin.  This insures that they cook evenly and that they cook through.  I use an inexpensive Mandolin type slicer from the grocery store, but you can use your food processor or a knife, just go for thin, even slices.


You don’t have to peel!  There is so much texture and vitamin content in the peel, just scrub your potatoes thoroughly before slicing.  Once sliced toss them in a bowl with cream and salt.


Transfer potatoes into a lightly greased deep casserole dish.  You can layer by color if you want to drive yourself crazy but it’s really not necessary, just try to have them mixed up well.


Top with some cheese, then cream


and more cheese…Hey it’s Thanksgiving remember!


Now cover tightly with foil and refrigerate until you are ready to bake.  If you want to do this the day ahead, partially bake potatoes for 40 minutes, covered.  Cool and refrigerate overnight.  Before serving, bring to room temperature, then uncover and bake for 30-45 minutes until hot, golden and bubbly.

Tip #2: allow plenty of time for baking!  If potatoes are properly sliced you shouldn’t have any problems, but these need time! Bake ahead and reheat if necessary.  We had these leftover 2 nights later, reheated covered at 350 for 40 minutes in the oven and they were just as good as the first time!

Let the gratin set for 5-10 minutes then cut into squares like a lasagna. You can see the different colors of potatoes

Here’s the recipe:

SWEET POTATO GRATIN from Southern Living magazine, November 2013

for a printable version click here

2 large sweet potatoes

2 large russet potatoes

1 1/2 T salt

1 1/2 cups heavy cream, divided

6 oz Gruyere cheese, grated

Wash potatoes well, and do not peel.  Slice into even thin, 1/8″ slices with a mandoline or sharp knife.  Place slices into a large mixing bowl and pour in 3/4 cup cream and the salt.  Gently toss potato slices to coat with cream.  Transfer slices into a lightly greased 2 quart deep baking dish or gratin pan, spreading potato slices into flat even layers.  Sprinkle with 1 cup, 4 oz. of cheese. Pour the rest [3/4 cup] of cream over potatoes and top with the rest of the cheese.  Cover loosely with aluminum foil.  Bake at 400 for 40 minutes.  Uncover and bake 20 to 25 more minutes until potatoes are tender and golden.  Test doneness by inserting a sharp knife, it should slice easily through the potatoes.  Let set for 5-10 minutes and cut into squares to serve.  Makes 8 servings.

Make ahead.  If you want to make the day before, bake covered potatoes for 40 minutes at 400.  Remove, cool and refrigerate.  Before serving bring dish to room temperature and continue baking uncovered until potatoes are tender and golden for about 30-40 minutes.

Once baked, leftovers can be reheated, covered and baked at 350 for 30-45 minutes.

Thanks so much for stopping by!

  1. You have just reminded me to put a mandolin on my christmas wish list☺ Again another fabulous recipe.


  2. They sound great and I love the pretty colors! I made scalloped sweet potatoes one year and they were a big hit, the cheese can only make them better:@)


  3. I am so happy you are doing the recipe testing for me! I have been reading through all these, thinking that I am going to try some new things this year, too. This looks so good. For years I used Julia Child’s version, which has no sweet potatoes, but this looks even better. I need a mandolin, too.

    Jenna, You’re speaking my language~ potatoes and not peeling them! I made a sweet potato and Yukon gold potato gratin from SL a couple of years ago, Yours looks so much easier and just as delicious, I could eat every bite with that cheesy goodness on top!
