Add sweet potato gratin to your list of sides this Thanksgiving. A mixture of bacon, onion and garlic, along with Gouda cheese, makes this layered dish a welcome addition to your menu.

Sweet potatoes are rich in Vitamin A so, if you’re not planning to use them right away, store them in a cool, dark, well-ventilated place for up to ten days.

If you have a mandolin slicer you’ll want to use it instead of your food processor. The blade’s super sharp (be careful!) and cuts neater, thinner slices for more uniform cooking. Besides, it’s much easier to clean than a food processor.

  • Preheat oven to 375 degrees.
  • Cook bacon in a medium sauté pan until crispy then remove and crumble, reserving 1 Tbsp of the drippings in the pan.
  • Add onions to the pan with bacon drippings and sauté until translucent. Add garlic, stir then remove from heat. Toss with bacon crumbles and set aside.
  • Melt butter in a medium saucepan. Whisk in flour for 1 minute then slowly whisk in the cream until there are no lumps. Simmer for approximately 5 minutes until thickened.
  • Stir in salt, pepper and thyme then remove from heat. Spread a layer of sweet potato slices evenly in a 9" x 13" pan, overlapping slightly. Season with salt and pepper then spoon ⅓ of the bacon mixture over the potatoes. Pour ⅓ of the cream mixture on top and sprinkle with ⅓ of the cheese.
  • Repeat steps until the potatoes and bacon are gone. Finish with the cream mixture and cheese.
  • Bake 35–45 minutes, or until bubbly. Enjoy.
