Sweet potatoes make it special.
Slice up orange and white spuds and you’re on your way to this gratin (pronounce sort of like “baton,” which essentially means anything layered with tons of cheese and cream). You can do onion gratin, zucchini gratin, you get the idea…).
Ingredients
- 2¾ cups heavy cream
- 2 teaspoons kosher salt
- 1 teaspoon freshly ground black pepper
- 3 cloves garlic, finely minced
- 1 tablespoon chopped fresh thyme (or ½ tablespoon dried), plus more for garnish
- 1 teaspoon chopped fresh rosemary (or ½ tablespoon dried)
- 1 tablespoon chopped fresh sage (or ½ tablespoon dried)
- ¼ teaspoon finely grated nutmeg
- Dash of cayenne pepper
- 2 cups (4 ounces) shredded gruyère cheese
- 2 cups (2 ounces) finely grated Parmigiano Reggiano cheese
- 2 pounds sweet potatoes, scrubbed
- 1½ pounds Idaho or russet potatoes, scrubbed
Directions
1
Preheat the oven to 425°F. Whisk the cream, salt, pepper, garlic, thyme, rosemary, sage, nutmeg, and cayenne in a big bowl. Toss the gruyère and Parm in another bowl.
2
Peel both kinds of potatoes, then use a handheld mandoline slicer or a sharp knife to slice the potatoes into 1/8-inch-thick rounds.
3
Pour ½ cup of the cream mixture on the bottom of a 9-x-13-inch casserole dish, then layer one color of the potatoes in as nice of a shingled pattern as you can, overlapping them slightly. Drizzle ¾ cup of the cream mixture on top, then sprinkle 1 cup of the cheese mixture on top of that. Repeat with another 2 layers of cream, potatoes (alternating layers between types of potatoes), and cheese, then finish with a top layer of potatoes and sprinkle cheese on top of that. Garnish with fresh thyme.

Cover with foil and bake until bubbly, 30 minutes. Remove the foil, reduce heat to 400°F, and bake until the top is golden and bubbly, 30 minutes. If you want a browner top raise the hest to broil and broil, watching carefully, until the top is a deeper golden brown, 1-2 minutes. Remove from the oven and allow to cool slightly before serving.
Should the cooking times be flipped? The first bake is 45 minutes with foil on and the second is 15 with foil off?
Made this the other day from the recipe in Cravings “Hungry for More” page 123 says 30 minutes with foil and 30 mins without then broil for 1-2 mins. It turned out amazing. Hope that helps.
can you make this the day before and then just warm it back up?

I made this the other day for my husband and his friends and everyone was yelling “Thank You Chrissy Teigen!” after trying it. Absolute hit.
I want to shout it from the rooftops how much I love this dish! I made this for our Thanksgiving and will be making it again for years to come. This satisfied my tastebuds beyond measure and had me craving more for leftovers.
We made these for thanksgiving and they were delicious but a bit greasy. Has anyone tried reducing the cream? TIA.
