My Savory Twist on Two Classic Casseroles

Sweet Potato Lovers Unite!

Today I’m sharing the most luscious and velvety sweet potato casserole recipe you’ve ever tasted.

And you thought baked sweet potatoes with marshmallows were lavish…

Although I realize traditional marshmallow-topped Thanksgiving sweet potatoes are placed by many on a high pedestal, there are those of us who like to occasionally serve sweet potatoes without added sugar.

That’s not to say we (ok, I) don’t add a whole lot of naughtiness, other than sugar. But sometimes it’s nice to indulge in the more savory and cheesy side of sweet potato side dishes.

This Garlic Butter Scalloped Sweet Potato Casserole is LOADED with butter, cream, and Parmesan cheese, to combine the best of your two favorite seasonal side dishes – classic scalloped potatoes and baked sweet potatoes – into one perfectly delicious celebration of fall.

How To Make Garlic Butter Scalloped Sweet Potatoes

  1. Mix the Cream Topping – In a small saucepan over medium heat or in a microwave safe bowl, combine all the ingredients except the sweet potatoes and Parmesan cheese. Whisk well and often until the butter is just melted. This should be done first so you can quickly pour the mixture over each sweet potato as you slice and place into your baking dish, to ensure that the slices do not brown.
  2. Peel and Slice the Sweet Potatoes – Peel the sweet potatoes one by one. Take care to slice each potato into very thin rounds, to create a delicate texture after baking. Just like your classic scalloped potatoes recipe!
  3. Arrange and Coat – After thinly slicing each sweet potato, arrange the slices in a pretty pattern in the baking dish. The pattern you choose is entirely up to you. Pour a little of the melted garlic herb butter and cream mixture over each thin sweet potato slice, before slicing the next one, to slow oxidation.
  4. Bake Your Casserole – Bake in a 400 degree preheated oven for 30 minutes, until potatoes are soft. Then sprinkle with Parmesan cheese and bake for a few more minutes, until the cheese is melted and your scalloped sweet potatoes are golden brown.

Garlic Butter Scalloped Sweet Potatoes Q&A

Can this scalloped potato recipe be made with other varieties of potatoes?

Absolutely. Feel free to use white or purple sweet potatoes, as well as russets and new potatoes in this recipe. Cooking instructions for your scalloped potatoes will stay the same.

Is this Garlic Butter Scalloped Sweet Potatoes recipe gluten free?

Yes it is! Thankfully, sweet potatoes are naturally gluten free.

Is this recipe low carb or ketogenic?

No. Sweet potatoes are starchy, therefore they do contain ample carbs. However, if you remove the cornstarch and use arrowroot powder instead, this scalloped sweet potato recipe is grain-free.

Simple Garlic Butter Scalloped Potatoes Recipe #ASpicyPerspective #Thanksgiving

Can I make a dairy free variation?

Yes! For Vegan Garlic “Butter” Scalloped Sweet Potatoes you can substitute thick coconut milk for the cream, and vegan butter for regular butter. Then omit the Parmesan cheese.

P.S. – If you happen to make this as a vegan scalloped sweet potato casserole, and use arrowroot powder instead of cornstarch, then this becomes a paleo recipe!

Is there a low fat version of this recipe?

Hmmmm… You could omit the cream and butter. Then brush a little olive oil over the top of the sweet potatoes, and add the garlic and herbs. The scalloped potatoes will not have the same silky luxurious texture in the end. However, they will be soft and herbaceous.

Can I freeze this recipe?

Due to the cream and butter in the scalloped potatoes, I wouldn’t freeze.

Can I make this recipe ahead?

Yes. You can prep and bake these scalloped sweet potatoes up to 3 days in advance. Then reheat uncovered in a 350 degree oven for 20+ minutes.

Garlic Butter Scalloped Sweet Potatoes - A luxurious sweet potato casserole recipe rich with cream, butter, cheese, herbs, and garlic. Your family will love this fall twist on classic creamy scalloped potatoes. Recipe with video.
Servings: 12


  • 3 pounds sweet potatoes
  • 1 1/4 cup heavy cream
  • 1/2 cup butter
  • 6 cloves garlic, minced
  • 2 tablespoons fresh thyme, chopped
  • 1 teaspoon cornstarch
  • 1/3 cup Parmesan cheese
  • Salt and pepper


  • Preheat the oven to 400 degrees F. Pull the leaves off the thyme stems. Discard the stems and roughly chop the leaves.
  • Place the cream and cornstarch in a small bowl or pot. Whisk well. Add the butter, garlic, thyme, 1 1/4 teaspoon salt, and 1/2 teaspoon pepper. Heat over the stovetop, or in the microwave, just until the butter melts. Then turn off the heat and whisk again. 
  • Peel and slice each sweet potato one by one. Slice the potatoes into very thin rounds, 1/8-inch thick. Arrange each potato in a 9x13-inch baking dish, fanning it out in a pretty pattern. 
  • Before peeling and slicing the next sweet potato, pour a little of the cream mixture over the potato slices in the pan, so it does not brown while you work on the other potatoes. 
  • Repeat until all the sweet potatoes are sliced and arranged prettily in the baking dish. Then pour the remaining cream mixture over the top.
  • Bake for 30 minutes. Sprinkle Parmesan cheese over the sweet potatoes. Then bake another 10 minutes until the cheese is golden. Serve warm.

  1. Yum!!!!!!! It says it all!

  2. I made this for Thanksgiving and followed the directions exactly as written.  Something however, must have gone wrong.  The recipe states that it will serve 12, but somehow 4 of us nearly finished off the entire 9×13 pan!! 🤣.  TOO TOO GOOD!!

  3. Made this today for thanksgiving. Added some rosemary along with the thyme as I had some extra and it was a huge hit! Got many compliments on the dish and will make again! Such a fun way to change up the traditional sweet potato. 

  4. Pingback: Garlic Butter Scalloped Sweet Potatoes (Video) – A Spicy Perspective – My Blog

  5. I made this to recipe but added a small amount of sliced onions. It was swimming in butter.  My better half loved it.  I will make again with half the butter   

  6. I add pineapple juice a 1/4 cup. And I purée some pineapple and add to the cream mixture.  I also add some Asiago to the Parmesan these really give the dish a little extra pop !!! 

  7. Can I use cheddar instead of parmesan??

  8. Delicious ! But I would use half the butter and thyme next thyme! :) but sooooooo good!! 

  9. Made this for Thanksgiving with canned coconut milk and it was fantastic! All the garlic and herbs flavored it perfectly and it did not taste coconut-y at all. Definitely a keeper!

  10. Made this up last night and it was great… Thinking of making it for Christmas dinner with a different twist. Cotija: called the “Mexican Parmesan”, Cumin instead of the thyme and a can of diced green chilies. On second thought I might not wait until Christmas

  11. I have made these twice, doubling the recipe both times, and no matter how many or few people I am serving they are always GONE! Sweet potatoes + garlic + buttery cream = MAGIC. Traditionally I’ve made them near/on Thanksgiving, but they will definitely be going into the winter rotation as my whole family adores them.

  12. This was delicious! I added a little bit of sliced green onion and slightly increased the amount of Parmesan sprinkled on top. It was wonderfully savory, but still allowed the sweetness of the sweet potatoes to come through.

  13. I made it with sweet and red potatoes. I diced an onion to put in and I covered it with ham steak cut up. When it only had 10 minutes left I sprinkled the parmesan and cheddar on top. My house smelled awesome. It was really good.

  14. perfect, thank you! I added sliced potato as well, just sliced the potato about half the width of the sweet potato so that they would be ready at the same time. Also, I added cottage cheese to the cream cheese, to thicken it up a bit.

  15. Sweet Potatoes!  Yes!  What a fabulous idea!  Can’t wait to try them!

  16. WOW!! Such an incredible side dish!! My family would LOVE this!

  17. These look so good! I’m definitely adding these to our dinner menu next week!

  18. This is a perfect dish to add to any dinner!!! Sounds so delicious!

  19. I’m cooking this right now, but I’m not serving until 6:00 pm tomorrow. How do you recommend reheating this recipe?

  20. My family loves sweet potatoes! I am making this dish this weekend!

  21. These are exceptional. So delicious.

  22. Such a flavorful side dish! And easy to make.

  23. what a great way to enjoy sweet potatoes!! thanks!

  24. Absolutely LOVE this sweet potato twist on scalloped potatoes. Loving that garlic butter deliciousness! Thanks for including our sweet potatoes with marshmallows :)
