Well, now that Halloween is over, get ready for all things Thanksgiving! Stuffing, turkey, cranberries, and of course ,sweet potatoes!

You all know the classic Thanksgiving sweet potato casserole topped with marshmallows? This is nothing like that. Not that I have anything against that iconic dish.

These scalloped sweet potatoes are sort of sweet potato casserole’s sophisticated older sister. They are rich and decadent, with so much flavor, thanks to bacon and shredded Gruyère cheese.

To increase the flavor profile even more, I take it one step further and roast the potatoes with a little maple syrup. You could boil them if you wanted to….but why? I’m clearly biased towards roasted vegetables (more than 40 recipes!) but roasting the sweet potatoes really does make a difference to this recipe. It’s a pretty simple step to do while you’re preparing the sauce, shredding the cheese, cooking the bacon, etc.

Today, I used a shallot instead of onion in these sweet potatoes, partly because Ben doesn’t like a really strong onion flavor, but mostly because I didn’t have any onions. What kind of food blogger runs out of onions? The kind of food blogger with two toddlers, that’s what kind. My point is, shallots are awesome but onions are great too. Use about a half of a small yellow onion — a 1/4 cup to a 1/2 cup would be perfect.

Decadent scalloped sweet potatoes will be an unforgettable side dish on your Thanksgiving table. Full of rich Gruyère cheese and flavorful bacon, they are sure to be a hit!

Ingredients

  • 3-4 sweet potatoes (about 3 lbs), peeled and sliced into ¼-inch rounds (cut rounds in half if very large)
  • 2 tablespoons olive oil
  • 1 tablespoon maple syrup
  • 1 teaspoon kosher salt, divided
  • ½ teaspoon coarse black pepper, divided
  • 3 strips thick sliced or center-cut bacon, cut into ½ iinch pieces
  • 1 large shallot, thinly sliced
  • ¼ cup all-purpose flour
  • 2 ½ cups 2% or whole milk
  • 1 ½ cups heavy cream
  • ½ teaspoon dried thyme
  • ⅛ teaspoon grated nutmeg
  • 6 oz. Gruyère cheese, shredded

Instructions

  • Preheat oven to 425ºF. Mix sliced sweet potatoes with oil, maple syrup, [1/2 teaspoon] salt and [1/4 teaspoon] pepper. Arrange on large rimmed baking sheet (sheet pan). Roast for 25 minutes.
  • Meanwhile, fry bacon in a large skillet over medium-high heat until almost crisp. With a slotted spoon, remove bacon from pan and set aside on a paper towel-lined plate.
  • Reduce heat to medium, add sliced shallot, [1/2 teaspoon] salt and [1/4 teaspoon] pepper to bacon drippings and cook until tender. Stir in flour, cooking and stirring about 1 minute. Add milk, cream, thyme and nutmeg slowly while whisking, increase heat to medium, and cook until mixture thickens slightly, about 5 minutes. Remove from heat and stir in all but 1/2 cup of the Gruyère cheese.
  • Arrange half of sweet potatoes in greased 9x13 inch baking dish. Cover with half of the sauce and sprinkle with half the bacon.
  • Arrange remaining sweet potatoes on top, cover with remaining sauce, and sprinkle with bacon.
  • Bake at 325ºF for 20 minutes, serve immediately.

Verdict: These are amazing! 
Husband’s take: Heard no complaints from him!
Changes I would make: None are necessary, but if you want to bulk this up a little to increase the servings, you could easily add another sweet potato. There is plenty of sauce and cheese to go around.
Difficulty: Easy to moderate.

    sweet potatoes > all other potatoes.
    this sounds sooooo delish! I wasn’t going to make a thanksgiving dinner this year, I was thinking of going totally non-traditional, since itll just be the four of us, but this one single dish is trying really hard to change my mind. LOVE.

    Oh forget the marshmallows! I never cared for my sweet potato casserole with them….plus the gruyere is amazing! I make something real similar. But I am loving your scalloped version!

    Move aside marshmallows, because there is a new goodness in town and it’s name is Gruyere and bacon!
    I love scalloped potatoes, but I have never tried then with sweet potatoes. And then you add Gruyere and bacon and I died. Pinned!
