Instructions

Preheat the oven to 400°
Into a medium saucepan add the 2 cups half and half, 3 tablespoons fresh chopped sage, 1 tablespoon fresh chopped rosemary, 2 teaspoons fresh chopped thyme, 2 cloves garlic, ¼ teaspoon kosher salt and ¼ teaspoon freshly ground pepper. Bring to a simmer over medium-low heat, stirring occasionally. Simmer the mixture until reduced by about ¼. (Don’t boil the cream mixture.)
In a medium skillet, melt 2 teaspoons butter over medium heat and add the 1 large granny smith apple. Sprinkle with ¼ teaspoon ground nutmeg and cook until the apples are tender, but not soft, about 3-5 minutes. Set aside.
In a medium bowl, whisk 3 large eggs together, then, in a slow, steady stream, whisk in about ⅓ cup of the hot cream mixture. (This is to temper the eggs without scrambling them.) Once the first ⅓ cup is fully incorporated, whisk in the remaining cream and herb mix until well combined.
Spray a medium casserole dish with vegetable spray. Layer ⅓ of the 3 medium sweet potatoes in the bottom of the dish, overlapping them. Sprinkle half the apples over the sweet potatoes, followed by ⅓ of the ⅓ pound bacon,⅓ of the cheese and ⅓ of the cream mixture. Continue with a layer of sweet potatoes, apples, bacon, cheese and cream. Finish with a final layer of potatoes, bacon, cheese, and the cream mixture.
Cover tightly with tin foil and bake for 40 minutes or until potatoes are tender.
Remove the foil and continue baking for an additional 20-25 minutes, or until golden brown and bubbly. Let rest for ten minutes before serving to set.
