Are you a turnip lover?

Turnips aren’t one of those happy-go-lucky neutral vegetables, like green beans for example, that seem to get along with everyone.

No, turnips have a bit more “I dare you to eat me” attitude, that unfortunately ends up keeping too many people away from them.

Well, if you are a turnip lover, you should be drooling right now, just with the very concept of this turnip gratin, a casserole layered with thinly sliced, tender turnips, onions, bread, and bubbly browned Gruyere cheese.

You will not be disappointed (at least I hope you won’t).

Turnip Gratin

If you fall in the “uh, maybe not, no, no thank you” camp, if there is one recipe that could possibly change your mind, this is it. We have made it 4 times in the last 2 weeks and will likely find its way to our Thanksgiving table this year.

So, if you’re on the fence, give it a shot!

Turnip Gratin Recipe

  • Prep time: 15 minutes
  • Cook time: 35 minutes
  • Yield: Serves 4

This recipe serves four, but it can easily be doubled. If you double it, use a 9x13 casserole dish.

This recipe works best with young turnips with relatively high moisture. Large old turnips, or storage turnips, that are tougher and drier may need to be blanched for more than 3 minutes.


  • 2 medium sized young turnips (about 1/2 pound total), peeled, and sliced 1/8-1/4 inch thin
  • Extra virgin olive oil
  • 3-4 slices white bread (enough to make two single layers in the pan), crusts removed
  • A few slices of onion, very thinly sliced, enough to cover the pan in one layer
  • 4 ounces Gruyere cheese
  • Salt and pepper
  • 8x5 baking pan or casserole dish


1 Blanch raw turnip slices: Preheat oven to 325°F. Blanch the raw turnip slices in salted boiling water for 3 minutes. Remove from water and drain.

2 Layer bread, turnip slices, onions, cheese in casserole dish: Coat the inside of the casserole dish with olive oil. Place a layer of bread on the bottom of the casserole dish. Layer on half of the turnip slices in a single layer, season with salt and pepper.

Layer on all of the onions. Sprinkle with half of the cheese. Add another layer of bread, turnips, and cheese. Sprinkle again with salt and pepper.

3 Bake: Place casserole on top rack of oven. Bake at 325°F for 25 minutes. For the last few minutes, if you want, and you are using a pan (metal or ceramic) that can safely handle broiling temperatures, broil for a couple minutes to brown the top.

Remove from oven and let cool for 10 minutes before serving.

    I have made this dish several times with great success. I have used various white cheeses that are sharp, including Asiago, manchego, aged Gouda and my personal favorite, Prairy Breeze from Iowa. It has small calcium crystals in it and the tiny crunch is amazing. It is available online. Usually I only eat the greens and wondered what to do with the turnips themselves.
    If you are lucky enough to have leftovers, it is terrific reheated with a poached or fried runny egg. The most delicious brunch item ever and your veg friends will love you forever!

    Delish! Subbed provolone because that is what i had on hand. Thank you for sharing :)

    Just going to throw this together, with fingers crossed! Has anyone assembled this ahead of time then cooked it when the company arrives? I just blanched the turnips, cooked the onions in butter and brown sugar and thought I may pour a little cream over it at the last minute if it can be made ahead.

    My husband and i had this tonight and it tastes amazing. While its true it can be just a bit dry, esp the bread area at the bottom, we might dip the bread in cream or beaten eggs next time for added moisture. A must try! This will be a staple turnip meal in the household :D Thanks!

    I had the same problem with the items not bonding(lack of liquid) the first time I made this dish as well. After a day or two the items finally did bond and this dish was wonderful as leftovers. What I do now is chop all the ingredients rather than slicing (everything including bread is in bite size pieces), blanch the turnips about 5 minutes instead of 3 and it’s really a great dish now. I’ve even had two other family members ask me for the recipe.
