Recipe by: Bako Sweet

Prep time: 20-25 minutes | Cook time: 45-50 minutes | Yield: 8-10 servings

Ingredients

  • 3 lbs Bako Sweet® sweet potatoes, peeled and sliced ⅛” thick on mandoline

  • 1 cup (3.5 oz) grated gruyere

  • ½ cup (2 oz) grated sharp cheddar cheese

  • ½ cup (1.5 oz) grated parmesan cheese

  • 2 garlic cloves, minced

  • 4 sprigs fresh thyme, leaves removed from stems and finely chopped

  • 1 1/2 cups heavy cream

  • ½ tsp freshly grated nutmeg

 

Directions

  1. Preheat oven to 375 F.

  2. To a saucepan, add the cream, garlic, thyme, and nutmeg. Bring to a simmer and reduce for about 5 minutes. Do not let the cream boil. Add salt and pepper to taste. Remove from heat and stir in ½ cup of gruyere until melted and smooth.

  3. Grease a baking dish with butter. Place the sweet potato rounds, overlapping in concentric circles to make the first layer. Top with ⅓ of the cheese. Repeat creating two more layers of potatoes and cheese. Slowly pour the cream mixture over the potatoes and cheese. Top with some additional fresh thyme.

  4. Bake for 45-50 minutes or until the potatoes are tender. Let rest for 10-15 minutes before serving. Garnish with more fresh thyme if desired.

  5. Enjoy!
