Parsnip Gratin - a cheesy, comforting, delicious side dish

If a parsnip could talk, it would speak words of wisdom and read Robert Frost poems.

It would teach you about the past so that you could understand the present and youโ€™d silently absorb everything the little root had to say. Donโ€™t be surprised if parsnip wears a manacle and loafers as parsnips enjoy simple comforts.

Personifying the parsnip may be new to you but given its calm, oaky, knowing voice, youโ€™ll beckon parsnip to continue its intoxicating fables.

This creamy, cheesy parsnip gratin recipe is a confident, sophisticated dish with warm, earthy, herby flavor and an un-expecting ease. It does its own thing.

In case you are new to parsnips…

Parsnips have a naturally nutty, somewhat cinnamon flavor, which is not for everyone as it is certainly different from the neutral potato.

The Inspiration for This Recipe:

Out of a successful pinning session, I found a recipe for Parsnip Gratin with Gruyere and Thyme from Feasting at Home.

I was instantly intrigued and was excited to finally make it, although I did make some modifications to the recipe.

Parsnip Gratin

Parsnip Gratin Ingredients:

Fresh Cauliflower: The main ingredient for the gratin sauce. As opposed to using heavy cream, I blended up steamed cauliflower with 2% milk and an egg for extra nutrients and less fat.

While I am absolutely sure heavy cream would be delicious in the parsnip gratin, I did not feel as though it was the dish was lacking it.

Fresh Parsnips: The star of the show. We need 2.5 pounds of fresh parsnips. They are found next to the other root vegetables and look like large white carrots.

Cheese: I used aged white cheddar cheese instead of gruyere only because gruyere skipped town the day I went to the grocery store.

Eggs and Milk: Used in the cauliflower sauce for a creamy consistency.

How to Make Parsnip Gratin:

  1. Steam half a head of cauliflower until soft when poked with a fork (about 5 to 8 minutes). Drain the cauliflower and set aside to cool.
  2. Over medium heat, sautรฉ the sliced onion in a couple teaspoons of oil until fragrant and beginning to turn translucent, about 5 minutes.
  3. Once the cauliflower is cool, combine the steamed cauliflower, milk, flour, salt, nutmeg and thyme in a blender. Blend until combined
  4. Crack the egg into the cauliflower/milk mixture and blend just enough to combine. This should make just over 3 cups worth of mixture.
  5. Preheat the oven to 400 degrees.
  6. Cover the casserole dish with foil and bake for 50 minutes. Remove the casserole dish from the oven, discard the foil.
  7. Put the casserole dish back in the oven (uncovered) and bake an additional 15 to 20 minutes or until golden brown. Allow the dish to sit 10 minutes so before you serve.

This dish encourages you to slow down and slip into the fuzziest socks you own and enjoy the process of connecting with real ingredients.

It is happy to join you while the sun descends and wonโ€™t get bent out of shape if you share a bottle of wine and light hearted chatter with it over some calm tunes.

If you have not tried parsnips before, I would recommend starting with a simpler and less time intensive recipe before taking the plunge. If youโ€™re a seasoned root eater, youโ€™re welcome!

Questions and Reviews

  1. I highly suggest cutting the milk portion in half. The dish was delicious but, it was swimming in sauce and my family thought it was to runny.

  2. WHOA. You did NOT find a way to swap out the cream in a gratin! Ugh you’re so brilliant, I just love it. Almost as much as I love a good gratin. Maybe more. Ok, at least equal. ๐Ÿ˜‰
