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
Preheat oven to 375 F.
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.
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.
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.
Enjoy!
