Cheese Herb Potato Gratin is the impressive side dish you’ll want for the holidays, but can eat all year long. Impossibly thin leaves of potatoes stack sideways in a skillet with herbs and cheese for a deeply satisfying, comforting dish.

I’m all about the side dishes for holiday and special dinners. I could fill up my plate with all the sides, and I might forget to hit the main dish. Are you like that, too?

Bring on the stuffing, vegetables, grains, pilafs, chutneys, sauces and most of all, bring on the potatoes! White, gold, sweet, purple — we like them all, and they all find a home at our dinners. 

Today’s dish cleverly combines both gold potatoes and sweet potatoes, for the best of both worlds, full of herbs — both dried and fresh — and flavorful cheese. It’s a marvel of lacy delicacy that looks far more complex than it is. In fact, putting this together is far faster than you imagine when you look at it. Trust me, you will be done and say to yourself, “That wasn’t as hard as I thought it would be!”

Want to wow your family for Thanksgiving of a fall or winter holiday dinner? Cheese Herb Potato Gratin is it.   

How to make Cheese Herb Potato Gratin

Ingredients for Cheese Herb Potato GratinFirst, assemble your ingredients. The recipe called for dried parsley and rosemary, but I had fresh versions of both, so used fresh. The rule of thumb is twice-t0-three-times as much of the fresh as you use of the dried. Go with your gut on that, and don’t overplay the thyme.

Slice the potatoes with a mandolinSlice the potatoes — both Yukon Gold and sweet potatoes — very thinly. A mandolin really helps do that quickly.

Sliced potatoes on a cutting boardYou can do it with a knife of course, but it will take a lot longer. It’s a lot of spuds!

Potatoes layered in a big stainless steel mixing bowl with herbsSeparate the potato slices from each other and add them to a very large mixing bowl, layering them with the herbs and spices, cheese and onion. It helps to layer them as you go, so they mix up nicely.

Hand scraping up all the leftover filling from the big metal mixing bowlIf there are any little snibbies of stuff left at the bottom of the mixing bowl when all the potatoes are in the skillet, just add the leftover stuff to the top of the dish. No waste!

Hand sprinkling reserved cheese over Cheese Herb Potato GratinSprinkle with a bit of cheese you have reserved.

Once baked and out of the oven, remove foil and allow to rest for a couple of minutes. It’s OK if there is a little liquid at the bottom. The potatoes will not be dry.

Prep Time: 30 minutes

Total Time: 1 hour, 45 minutes

Yield: Serves 8-10

Cheese and Herb Potato Gratin

Cheese Herb Potato Gratin is the impressive side dish you'll want for the holidays, but can eat all year long. Impossibly thin leaves of potatoes stack sideways in a skillet with herbs and cheese for a deeply satisfying, comforting dish.


  • 1 tablespoon olive oil
  • 3 medium sweet potatoes
  • 6 small Yukon gold potatoes
  • 1 teaspoon kosher salt
  • 1/4 teaspoon ground black pepper
  • 3/4 teaspoon garlic powder
  • 1/2 teaspoon dried thyme
  • 1/2 teaspoon ground sage
  • 1 1/2 teaspoons dried parsley (or 1-2 tablespoons fresh chopped parsley)
  • 1/2 teaspoon dried rosemary (or 2 teaspoons fresh rosemary finely minced)
  • 8 ounces Gruyère or sharp white cheddar, grated (2 cups)
  • 1/2 cup thinly sliced yellow onion, chopped
  • 1/2 cup whole milk or half-and-half
  • 1/2 cup low-sodium chicken broth


  1. Heat oven to 375ºF. Brush inside of a 10-inch cast-iron skillet with olive oil and set aside.
  2. Peel potatoes, and, using a mandolin or vegetable slicer, cut into very thin slices. In a large bowl and using your hands, gently toss potatoes with salt, pepper, garlic powder, thyme, sage, parsley, rosemary, cheese (reserve a little bit for the top), and onion, until everything is evenly mixed. Be careful not to break the thin potato slices.
  3. Working with a small handful of potatoes at a time, gently line up coated slices in prepared skillet or 2-quart baking dish. Sprinkle with reserved cheese. Pour milk and broth over potatoes. Cover pan with foil and seal around edges.
  4. Bake 50 minutes and remove foil. Continue to bake until potatoes are tender and top is golden, 15-20 minutes more. You can test the potatoes with a knife to see if they are tender throughout. Cool slightly and serve hot.
  5. Serves 8-10.

About the cookbook

LiveLifeDeliciously cookbook coverThis recipe came from “Live Life Deliciously: Recipes for Busy Weekdays and Leisurely Weekends,” by Tara Bench / aka Tara Teaspoon (2020; Shadow Mountain publishing) affiliate link. It’s a great book, and worthy of a spot in the home cookbook library. Tara helps you elevate your easy weeknight meals and take a shot at some more elegant party-type dishes for weekends when you might have additional time to cook. This gratin is a good example of both…if you can stack a deck of cards, you can make this with far less fuss than you imagine, AND it is showy enough to be the centerpiece for your holiday dinner. I have my eye on her Salmon, Veggie and Carrot-Ginger Rice Bowl, her Dill and Feta Orzo Salad, and her Pepperoni Pizza Pasta with Ricotta. That might be dinner tonight!
