Root Vegetable Gratin Recipe

Root Vegetable Gratin Recipe

Written by Becky

I have a crush on a local chef. Victoria from the Pinon Market in Salt Lake City is a genius when it comes to healthy, seasonal recipes. She came up with this delicious root vegetable gratin recipe this weekend as we created several healthy Thanksgiving Side Dishes at Sunday’s SLCmixer.  All of her recipes from that evening were amazingly delicious, using seasonal vegetables, and healthy substitutes, but this one was a favorite.

If you haven’t been to the Pinon Market and you live in Salt Lake, you must check it out. They have a delicious brunch, as well as lunch and healthy dinners to go. Victoria has been serving her community delicious food for over 15 years now.  You can read more about her restaurant and our SLCmixer with Pinon Market on SLCfoodie blog.

As for the root vegetable gratin, the recipe is actually quite simple and the beauty of it is, you can use whatever root vegetables you have on hand. If you don’t have celery root or maybe your just a little uncomfortable with the large gnarly brown root, try the pretty purple and white root vegetable- rutabaga. Both are not often used but have similar texture and flavor and may be used interchangeably. Rutabagas are slightly more sweet, while celery root taste similar to celery but more mellow. Either way, this layered root vegetable dish was a crowd pleaser for our event and I’m sure it will be for Thanksgiving as well.

  1. My grandparents are coming over for dinner yesterday and this dish was the first thing that popped into my head to make. I cannot wait just going to lighten it a little by substituting coconut milk creamer for half and half. Hope I don’t ruin it but doing that!

  2. Curious, can this be made without half-and-half? We don’t have a need for it except with this recipe so I’d hate to waste the product. thanks!

    • That’s a great question. You could try whole milk, cream, or maybe even yogurt if you have any of those around. I usually substitute dairies all the time with whatever I have on hand though I haven’t tried it with this specific recipe. Let me know what you end up trying and how it works!
