It’s time to start narrowing down your Thanksgiving menu, right? For people who are keeping it as low-carb as possible, I’ve given you 25+ Low-Carb and Gluten-Free Holiday Side Dishes, Appetizers and Salads as well as The BEST Low-Carb and Gluten-Free Thanksgiving Side Dishes, so if sweet potatoes are too high in carbs for you, go check those out!

But I love savory sweet potatoes and for a special holiday meal I wouldn’t pass up a small serving of this Sweet Potato Gratin. When I tested this recipe twice, (once with Jake and once with Kara), we absolutely could not stop eating these creamy sweet potatoes!  And if I had to pick my one favorite sweet potato recipe on the blog, it would have to be this one!

Sweet Potato Gratin is a holiday treat, so it’s a little more indulgent than the usual things you find on this blog. I love the combination of cheese and cream (or half and half) that gives such creamy flavor here, but the recipe also has a lot of healthy low-glycemic sweet potatoes. And it’s also gluten-free for anyone who needs that! And this could be assembled earlier in the day (or even the day before) and then cooked when it’s dinner time.

How to Make Sweet Potato Gratin:

(This is just a summary; scroll down for printable recipe.)

  1. Try to find long thin orange-fleshed sweet potatoes for this recipe (called yams in many U.S. stores.)
  2. Peel the sweet potatoes and cut in thin slices, about 1/4 inch thick.
  3. Layer the slices in a glass baking dish and season well with salt and pepper.  (I used an oval 4-quart baking dish, but as you can see from the photos any 3-Quart Baking Dish (affiliate link) would have been big enough, so don’t worry if that’s the size you have.
  4. Whisk together the softened goat cheese, thyme, and half and half.
  5. Spread half the goat cheese mixture over the sweet potatoes.
  6. Top that with half the Parmesan.
  7. Make another layer of seasoned sweet potatoes, goat cheese mixture, and Parmesan.
  8. Bake covered with foil in a pre-heated 375F/190C oven.
  9. Then remove foil and bake 20-30 minutes more, or until the top is nicely browned and sweet potatoes are soft when you stick a fork in.
  10. When I shared this on Instagram people immediately starting asking for the recipe; enjoy!

Sweet Potato Gratin

Yield 8 servings
Prep Time 20 minutes
Cook Time 1 hour 30 minutes
Total Time 1 hour 50 minutes

This delicious Sweet Potato Gratin has goat cheese, Parmesan, and thyme, and it's perfect for people like me who love savory sweet potato recipes!


  • 3 pounds orange-fleshed sweet potatoes 
  • salt and fresh-ground black pepper to taste
  • 10 oz. log soft goat cheese
  • 1 cup half and half (see notes)
  • 2 tsp. dried thyme
  • 1 1/2 cups coarsely grated Parmesan


  1. Preheat oven to 375F/190C.  Take goat cheese out of the fridge and let it soften at room temperature.
  2. Spray a 3-4 quart glass casserole with with non-stick spray or olive oil. I used an oval 4-quart baking dish, but any 3-Quart Baking Dish (affiliate link) would have been big enough.
  3. Peel the sweet potatoes and cut into slices about 1/4 inch thick.  (Don't make them too thick or they will take longer to cook.)
  4. Put the softened goat cheese in a small bowl, add the half and half and the thyme, and whisk together until it's smooth.  (You can put the package of goat cheese in the microwave and heat in 10 second intervals until it's soft to make this easier to mix.)
  5. Layer half the sweet potatoes in the baking dish and season well with salt and fresh-ground black pepper.
  6. Spread half the goat cheese mixture over the sweet potatoes and sprinkle on half the grated Parmesan.
  7. Make another layer each of sweet potatoes seasoned with salt and pepper, goat cheese mixture, and Parmesan.
  8. Cover the dish tightly with foil and bake 1 hour (or until the sweet potatoes are quite soft when you stick a fork in them.)
  9. Remove foil and bake 20 minutes more, until the sweet potatoes are very soft and the top is nicely browned. Serve hot.
  10. This will stay good in the fridge for several days and may have reheated a little too well, if you know what I mean.
  11. I haven't tried it, but I'm sure the dish could be assembled in advance, refrigerated, then allowed to come to room temperature when it comes out of the fridge and baked later in the day, or possibly even the next day.


Use heavy cream if you prefer.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Sweet potatoes are probably too high in carbs to make this Sweet Potato Gratin suitable for strictly low-carb eating plans, and this is kind of a rich dish for the South Beach Diet. But this is so much lower in carbs than traditional holiday sweet potatoes, and I’d eat this in small amounts for a Thanksgiving indulgence.

  2. I have made this several times, and I always prepare the dish a day ahead. I bring it to room temperature the following day, pop it in the oven and it comes out great. It has become a Thanksgiving staple. Everyone loves it.

  3. For some reason, my family doesn’t love sweet potatoes, so I’m always looking for new ways to cook them that just might appeal to my picky eaters. I’m adding this recipe to my list!

    • Lydia, this is so good for anyone who likes the savory flavors of goat cheese and Parmesan. Maybe that will win them over?

  4. This sounds absolutely wonderful. And I’d probably veer away from my purple potatoes and purple sweet potatoes to make this (I can tell you that purple mashed potatoes are weird, even though they taste good). I’m not doing a fancy TG dinner, but am definitely saving this recipe.

  5. Do you think it would be good with Feta cheese instead of Goat? I usually prefer feta to goat.

  6. My wife made this just now. Taste good. But I think she put too much cheese in it.

  7. Made this last night for Easter. It was freaking FANTASTIC!! Thanks for all you do here.

  8. Can you make this ahead of time?

    • As I said in the recipe, I haven't tried assembling in advance and cooking later, but I'm guessing it would work. You could also probably cook partially and then heat when you serve it, but I haven't tried that either so I can only guess that it would work. I'm guessing that because it's really good reheated, but if you try it I'd love to hear how it works. And if you have the option of cooking right before you eat it, that's probably going to give the best results.

  9. Tyler I haven't tried it but I am guessing that if you like the tanginess of buttermilk it would be great in this. I'd use the same amount. I'd love to hear how it works if you try it.

  10. Has anyone tried substituting buttermilk for half and half? If so, how was it, and did you use the same amount?

  11. Alice, great idea to make it in an 8X8 dish for a smaller crowd. So glad you and your guests have enjoyed it!

  12. I have made this a few times now. It is always a surprise hit at parties, because people are not expecting the savory flavors. I usually make 1/2 recipe, which works well in an 8×8 glass dish. Thanks for the great recipes, Kalyn.

  13. I've always preferred savory sweet potatoes (they ARE a vegetable) but I never thought about goat cheese – I love goat cheese…. I'm doing this one soon (but not Thanksgiving)

  14. This was so amazing! Thanks for letting me have some. I ate the leftovers for dinner and they were amazing!

  15. I'd love to see a few gluten free and dairy free recipes. It's hard to find good recipes for Thanksgiving that don't involve either one.

    • My site is loaded with recipes that are both gluten-free and dairy free. Scroll through the Can Be Paleo category to find them.

  16. I really wasn't sure what to make for Thanksgiving this year…I was thinking sweet potato casserole and I love how this is savory instead of sweet! Definitely a contender.

  17. Looks fantastic! Will give it a try and report back:-) Thanks.

  18. I bet this is so good! These flavors are perfection!

  19. Is it no longer possible to save messages to a recipe box on your site? Did I lose all my saved ones?

    • I wrote a reply to you right away, but now I don't know why I don't see it here. Hope you were not worried. The recipes are still there; you can access them from the Recipe Box link in the right sidebar.

      Ziplist is closing down the recipe box feature (not me!) You should have received an e-mail at the e-mail address you signed up with explaining how to move your recipes. They will be available until December 10. You can read the message from Ziplist at that link if it's not in your e-mail.

      I have only heard from two people about this (counting you) so I don't know if I will post about it, but here's a post from my friend Lydia with some more suggestions.

      Hope that helps. I am sad that they shut down, but I can't do anything about it.

  20. Love the combination of sweet potatoes and cheeses! I'm not hosting Thanksgiving this year, but if someone asks me to bring a side dish, I'll make this one.
