Herbed Sweet Potato Gratin

Today I’m exited to be a part of Anolon’s “Make It Yours” campaign where I get the chance to make a recipe my own by tweaking it to my little heart’s content. Now if I’m being honest, I do this in some way, shape or form everyday but this time it was fun to actually have a “mission” to take a classic recipe and give it a twist. And, what’s more of a classic than Julia Child’s recipe for Gratin Daphinois (Potato Gratin)? Alright, I know I’m messing with the queen here, but bear with me. The result is a decadent sweet potato gratin that is ridiculously good.

We’re starting with a pound each of russet and sweet potatoes that have been both scrubbed and peeled.

 Slice them up about an 1/8th of an inch thick and place in a bowl. If you’d like to slice the potatoes up ahead of time you can leave them in a bowl of cold water until you’re ready for them. Cut potatoes will brown if left for more 5-10 minutes in the open air.

Julia’s recipe is pretty simple: potatoes, cream, cheese, salt, and pepper. I decided to bring out some of the earthy-ness of the sweet potatoes by using some herbs. I used dried herbs for this, but if you have fresh use ‘em! It takes about 3 times the amount of fresh herbs as is needed for dry. So if you need 1/2 tsp of dried thyme, you’ll want 1 1/2 tsp if you’re using fresh thyme. Make sense? I like to put the salt, pepper, and herbs in a little bowl to make it easier to dump right into the cream when it’s time.

I’ve had the chance to try out several of Anolon’s Nouvelle Copper pans over the past several months and I’m in love! The one I’m using here is a 3 quart saute pan that comes with stainless steel lid. The pans are gorgeous and I’m loving how well they distribute the heat while cooking. I also love that the non-stick coating is metal utensil safe so I don’t have to be the silicone spatula nazi just to keep my pans looking nice. Keep reading for a chance to win one of your own!

Heat some cream, butter and garlic over medium heat and bring to a simmer.

 Remove from the heat and stir in the herbs, salt, pepper and cheese. I decided to go with sharp cheddar as opposed to Julia’s swiss cheese to offset some of the sweetness from the sweet potatoes. The cheese doesn’t have to be all the way melted, just stirred into the cream.

 If you’re smart you’ll take the spatula out of the pan before adding in the potatoes. Regardless, add the sliced potatoes to the pan…

 …and arrange them so that most of them potatoes are submerged in the cream mixture. Cover the pan with foil or a lid and bake for 3o minutes at 375 degrees.

 After 3o minutes they should look like these. The potatoes will be tender but there will still be a lot of liquid in the pan.

 Continue to cook uncovered until they are golden brown on top and crispy around the edges– about 20 minutes longer.

 What you’ll pull out of the oven can only be described as a big pan of splendor. It’s savory and creamy and slightly sweet and the perfect side dish for a holiday dinner party! I think Julia would approve.

    I might add a greater portion of sweet potatoes vs regular potatoes and/or figure a way to replace some of the cream with milk to keep the creaminess, but cut some of the fat.

  2. Tesuque says

    First, I want to stick to your recipe, but use fresh thyme from a windowsill planter. Next time, I may experiment with some chipotle, etc., for a Southwest flavor.

  3. Wild Child says

    These look so tasty! I’ve got some sweet potatoes just hanging out on my counter…guess I need to get some russets today and whip this up! Looks like a great recipe Heather – thanks

  4. Anne says

    I love the addition of herbs, but to make it my own, I might sprinkle the top with cheese toward the end of cooking, just long enough for it to melt and brown a little.

  5. Ray Langer says

    I would want to add a little more spice. Maybe pepperjack cheese and crushed flakes to give it a little kick.

  6. ANGELA REIMUS says

    To make this my own, I think I would trying adding sliced parsnips – I love the bit of sweetness they add to stews and roasts that I make, and I use potatoes/sweet potatoes in those, so I think it could work! Or maybe a small amount of sweet onions.
