Goat Cheese Sweet Potato Gratin Recipe with text

I cam up with this recipe years ago when I stumbled upon a blogger Improv challenge. Basically a theme was given which was two assigned ingredients. Then it is up to the bloggers to let the creative juices flow, and see what they could come up with. On the third Thursday of the month, we published our new recipes based on the theme.

This recipe truly started out as improv. I had a sweet potato and some white potatoes laying around, and I was really in the mood for goat cheese. So after digging around for some sort of scalloped, au gratin potato recipe idea for inspiration, I found Gratin Dauphinois (Scalloped Potatoes with Cheese) from Cooking Light. I did a little tweaking, and this is what I came up with.

Easy Sweet Potato Side Dish Recipe

This Goat Cheese Sweet Potato Gratin was yummy – a little sweet, a little salty, creamy, tangy. In fact, combining potatoes and sweet potatoes was the best of both worlds. It had the perfect hint of sweetness that tastes amazing with the tangy goat cheese and the hint of thyme. But the white potatoes tone down the level of sweet, and add more of a starchy, chewy texture versus the softer sweet potatoes. We all ate the leftovers with dinner the next night, and I had the last little bit the following day for lunch.

How do you make sweet potato gratin?

  • Preheat your oven to 450°F. Coat a glass pie plate with olive oil or cooking spray and rub with a cut clove of garlic.
  • Thinly slice your potatoes and sweet potatoes. I highly recommend a mandolin for this as it makes it quicker and ensure even slices.
  • While slicing the potatoes, gently heat the milk, some of the goat cheese, and fresh thyme.
  • Layer the ingredients, starting with potatoes, the milk mixture, sweet potatoes, more of the milk mixture, the rest of the potatoes, and the remaining milk mixture. Note that you can use all white potatoes, all sweet potatoes, or eve a slightly different ratio of each depending on what you have on hand.
  • Cover with foil and bake. Uncover, top with crumbled goat cheese, then continue baking until the top is browned and the potatoes are tender.
  • Let cool slightly, slice, and enjoy.

Is Goat Cheese Sweet Potato Gratin gluten free?

Potatoes and sweet potatoes are perfect options for gluten free side dishes. Since gluten in a protein found in some grains, and potatoes and sweet potatoes are starchy vegetables, not grains, they are definitely gluten free. Goat cheese is, as well. In fact many people who are highly sensitive and must avoid blue cheese ca use goat cheese as an alternative for that tangy flavor.

The only other ingredients in this recipe are olive oil, garlic, milk, and fresh thyme, all of which are naturally gluten free.

MANDOLINE SLICER – I highly recommend using a mandolin to slice the potatoes. It is much quicker and ensures the slices are the same thickness so they cook evenly. I have the older version of the OXO Chef’s Mandoline, but as you can see above, they are available in different styles and price points, with different blades and features. You do have to be very careful when using a mandoline, but it’s a helpful kitchen tool to have in your arsenal.

Goat Cheese Sweet Potato Gratin Recipe

The perfect blend of sweet and savory, the addition of goat cheese and white potatoes to this sweet potato side dish recipe truly make it amazing. The potatoes form a more firm, crisp layer around the tender sweet potatoes. And the thyme-infused goat cheese sauce and browned goat cheese on top make it irresistible. The whole family will love this easy recipe.

Goat Cheese Sweet Potato Gratin

A simple but sophisticated side dish with layers of thinly sliced potatoes and sweet potatoes baked until tender, creamy, and golden. 


  • 1 garlic clove, halved
  • 4 ounces goat cheese
  • 1 cup milk
  • 3-4 sprigs fresh thyme
  • 3/4 pound white potatoes, sliced 1/8 inch thick (see note)
  • 1 pound sweet potatoes, sliced 1/8 inch thick (see note)
  • 1 1/2 Tablespoons olive oil
  • 3/4 teaspoon kosher salt
  • black pepper


  • Preheat your oven to 450°F. Spray a 9 inch round glass pie plate with olive oil or cooking spray. Rub with the cut sides of the garlic. Discard the garlic.
  • In a pan, combine 2 oz. of the goat cheese, the milk and the thyme, and bring just to a simmer. Remove from heat and remove the thyme stems.
  • While the milk is heating, layer half of the potato slices in the pie plate, drizzle with 1/2 Tablespoon olive oil, 1/4 teaspoon salt, and black pepper. Repeat with one layer of sweet potatoes, then another layer of white potatoes.
  • Pour the milk mixture over the top of the potatoes, and lay the thyme sprigs on top.
  • Cover with aluminum foil and bake for 20 minutes.
  • Uncover, crumble the remaining 2 oz. of goat cheese and sprinkle on the top.
  • Bake uncovered for another 20-25 minutes, or until the potatoes are tender and the cheese starts to brown.


You can use all white or all sweet potatoes or a different amount of each for a total of about 1 1/2-1 3/4 lbs total.

  4. Brianne! What a beautiful gratin! I love how you described it all, sweet, creamy, tangy. And I love that you used both regular and sweet potatoes. The best of both worlds! So glad you are a part of Improv….Kristen is wonderful and it’s a great group of people!
