cheesy_root_vegetable_gratin Alright – we know you are probably seeing a million new Thanksgiving recipes you could try but we wanted to share another one with you. This is our Cheesy Root Vegetable Gratin. It is one of those dishes that is not only delicious but super super pretty. So that makes it really perfect for thanksgiving. Yes the cutting of the vegetables is a little time consuming but not if you have a mandolin! This side dish is packed with cheese and cream which makes everything taste better.

Cheesy Root Vegetable Gratin

Makes 1

1-2 long sweet potatoes (about 2 inches thick), peeled
4 large parsnips, ends trimmed and peeled
5 medium beets, peeled
2 1/2 cups heavy cream, divided (whole milk is fine, but mixture wont thicken as much or be as creamy)
4 ounces grated Parmesan, divided
1 tablespoon fresh minced thyme, divided, plus more for garnish
1 garlic clove, minced
2 ounces shredded gruyere
salt and pepper to taste

1. Preheat oven to 400˚F.
2. Slice sweet potato, parsnips and beets into very thin rounds (using a mandoline is easiest) and transfer each vegetable to its own bowl.
3. Pour 2/3 cup cream over each bowl of vegetables and top each with 1/2 ounce grated Parmesan and 1 teaspoon minced thyme. Season each bowl generously with salt and pepper and toss together until all vegetable slices are well coated.
4. Pour remaining cream into the bottom of a 2 quart (oval) baking dish and sprinkle with 1/2 ounce of Parmesan and minced garlic.
5. Grab a stack of sweet potatoes and line them standing up on a bias, at the top of the baking dish.
6. Follow the sweet potato with a row of parsnips, followed by a row of beets.
7. Repeat with the remaining sweet potatoes, parsnips and beets, creating 6 rows of root vegetables.
8. Season top of gratin with salt, pepper and sprinkle of remaining ounce of Parmesan.
9. Cover with foil and bake for 25 to 30 minutes or until vegetables are soft.
10. Remove from oven, uncover gratin and top with shredded gruyere.
11. Set oven to broil and broil gratin for 3 to 5 minutes or until browned and bubbling on top.
12. Finish with a sprinkle of fresh thyme leaves. Serve.

    Any tips for making sure that the colors don’t bleed and to ensure that all elements cook evenly?

    • loriann dyer Not Specified Not Specified

      Cut beets first, then soak your beets in cold water, drain and pat dry. Or grow or buy rainbow beets, they don’t bleed. You will be much happier with the results.

      • Kelley Not Specified Not Specified

        Actually, quite on accident I left the cut beets out and they dried a little bit and they did not bleed.

  2. DJ Not Specified Not Specified

    Personally, when I make this I will sub carrots for beets. Won’t be as colorful but it won’t suffer from beet bleed and I think I will like the flavors a bit more.

    Where did you get that pan?? It’s amazing, vintage?

  4. Sara Not Specified Not Specified

    Can’t this dish be made ahead and then frozen?

    • Jenny Park Not Specified Not Specified

      Hm, I’m not sure. I get weird about freezing things (trying to be better about it)…i worry the potatoes may get mushy, once you reheat…but maybe not! Perhaps others who freeze dishes more often may have better insight!

      • Barbara Not Specified Not Specified

        Potatoes don’t freeze well at all. Their structure breaks down & becomes soupy.

      • Arbancito Not Specified Not Specified

        Omit white potatoes only. Add rutabagas if desired. Cook completely, refrigerate until cold, cover with cling film, wrap with foil, and freeze. Thaw, remove cling film, replace foil, and heat. Bon ap!

    • loriann dyer Not Specified Not Specified

      Only par-bake this dish, it is better fresh but I did freeze it and finished the bake on the reheat.

    • Tim Not Specified Not Specified

      I got a similar pan as a gift – Mauviel from Williams Sonoma.

  5. Karen Not Specified Not Specified

    Can this made the day ahead of Thanksgiving and then just pop it in the oven?

  6. Candy Not Specified Not Specified

    This looks so delicious. Do you think the cream could be substituted with something other than dairy. My kids can’t have that much dairy, since there is also cheese in it. I would love to make this.

    • Jenny Park Not Specified Not Specified

      Hi! You can use a cow dairy alternative like almond milk or cashew milk. You may need to drain some of the excess liquid that gathers at the bottom of the dish, once you uncover the gratin, but should still work out just fine!

  7. Betty Not Specified Not Specified

    Will try this weekend. Any idea of calorie intake per portion? I know it shouldn’t really matter but I thought I’d ask

  8. Chelsea Not Specified Not Specified

    Did you (or anyone who has made this) have issues with beet bleed? Any advice for avoiding it?

    • Jenny Park Not Specified Not Specified

      I actually didn’t have any issues with beet bleeding. They bled a little bit, when they were tossed in a mixing bowl with cream, but not while assembling or baking :)

  9. Deb Not Specified Not Specified

    Looks beautiful. Can you substitute potatoes for the turnips and can you substitute broccoli crowns for the beets?

  10. Karen Not Specified Not Specified

    Some rutabaga sounds good.

  12. Tegan Not Specified Not Specified

    How many people do you think this would serve? It looks lovely!

  13. candace Not Specified Not Specified

    This recipe was SO delish and beautiful. We didn’t have Gruyere on hand so I subbed Raclette. This is one of my new fave recipes. Thank you.

  14. Nicole Massengale Not Specified Not Specified

    This looks delicious! Definitely going on my meal plan soon.

  15. Madara Not Specified Not Specified

    Do all the veggies cook evely soft during the given time? In my experience bertroots cook much longer than sweet potatoes, theough I haven’t tried to cook them sliced this fine, only whole in a foil..

  16. Marguarite Quinlan Not Specified Not Specified

    I made this for Christmas dinner in a lovely French oval baking dish my dad bought for my mom probably 30 years ago. It looked and tasted wonderful.

  17. Amber Not Specified Not Specified

    Hi! I made this and it didn’t cook through even spending twice the amount of time in the oven. The beets stayed hard. Sweet potatoes finally got soft. Did anyone else have this issue? The flavors were delicious, though.

  18. Judy Not Specified Not Specified

    Do you think it would be okay to leave the veg soaking in the cream mixture overnight?

    • Jenny Park Not Specified Not Specified

      I think that should be fine, but i would soak the vegetables separately to make sure the beets don’t bleed over everything!

  19. Noleen Herring Not Specified Not Specified

    This looks lovely but I was wondering if the parsnip might go off colour if i make it ahead of time. I thought the other vegetables would be ok.

  20. Ellsworth Not Specified Not Specified

    I made this for Valentine’s Day. I added golden beets as well. It turned out creamier then I thought but my honey loved it. Will definitely be making it again.

  21. Courtney Not Specified Not Specified

    I want to make this for Easter. Do you pour the leftover cream from each bowl back into the main serving dish with the other cream?

    • Jenny Park Not Specified Not Specified

      The cream that the vegetables are originally coated in are discarded to ensure the entire dish doesn’t become discolored (specifically from the beet infused cream)

  22. Robin King Not Specified Not Specified

    This recipe keeps coming to me every week. How do I break this loop?

  23. Kimberly Valdovinos Not Specified Not Specified

    I used a 2qt oval corningware ceramic dish as opposed to a Oval Baking Tray (because I didn’t have one on-hand)… Did not work as well as I thought for 2 reasons. One, because the extra depth meant that all the required cream pooled and left me with half-vegetable soup below the surface of the veggie rounds. Two, all the veggie rounds did not fit in the dish; I had to use another dish to make a mini version of this. I haven’t tried the mini yet, but I have a feeling it will be better than the large one because there was less of a cream pool at the bottom. Other than that, the dish was surprisingly satisfying.
