Why this cranberry-parsnip gratin recipe is so good
- This delicious parsnip gratin is dairy-free and Whole30 approved. We removed the cheese and cream for a healthy alternative. A cashew cream sauce gives this dish a creamy texture.
- Dried Cranberries add a nice pop of flavor! If dried fruit is not your cup of tea, this gratin is delicious without cranberries. I love the sweet and tart flavor cranberries bring to the table.
- Caramelized onions make everything taste better right. We slowly cook onions in ghee to bring out the natural sugars of the onions. What grows together goes together!

How to make cranberry parsnip gratin
Cranberry-Parsnip Gratin is so easy to make, here's how to make it:
- Peel and thinly slice parsnips on a mandoline. Slice the parsnips ⅛ inch thick. Tip - Be careful using a mandoline and toss away the inch of the parsnips. Cuts are common if you are not careful.
- In a medium-sized saute pan, heat 1 tablespoon of ghee. Throw in sliced onions and cook on medium-low heat for 15 minutes. This will bring out the sweetness of the onions. Cook until golden brown and caramelized.
- In a high-speed blender, combine almond milk and cashews. Blend on high speed for 1 minute or until thick and creamy.
- Grab your greased casserole pan and layer ⅓ of sliced parsnips.
- Top with ⅓ of cooked onions, cranberries, thyme, nutmeg, salt, and pepper.
- Drizzle with ⅓ of the cashew cream sauce. Go easy on the sauce.
- Repeat this process 2 more times. Top with reserved cashew cream, thyme, and nutmeg. Cover with aluminum foil and bake at 350 degrees for 1 hour.
- Uncover the casserole dish and bake for another 15 minutes or until golden brown.
Substitutions
Parsnips - Sweet potatoes and rutabagas make a great gratin as well.
Ghee - Butter, coconut oil, and avocado oil are great alternatives.
Herbs - Tarragon, thyme, chives, and parsley go well with parsnips.
Cashew Cream Sauce - Replace with 3 cups of full-fat coconut milk or heavy cream.
Dried Cranberries - Swap dried cherries out for cranberries or remove them from the recipe.
How to store and reheat gratin
How to Store: Cool gratin to room temperature, cover with plastic wrap and refrigerate for no more than five days. You can also transfer to an airtight container and refrigerate.
How to Freeze: Cool gratin to room temperature. Cut into individual portions and wrap with plastic wrap. Place into the freezer for no more than 2 weeks to preserve the texture.
How to Reheat: Place a portion of parsnip gratin uncovered into the microwave for 3 minutes or until hot.
Pro Tips
- Purchasing the right-sized parsnips. Go for the smaller-sized parsnip for better flavor. The larger ones have a woody and bitter flavor.
- Use a mandoline to slice parsnips. Every slice with be uniform in size and thin. I like to grip the end with a kitchen towel to prevent accidental cuts.
- Cook onions low and slow. The trick of caramelizing onions is to start on low heat. Allowing you to bring out the sugars gradually, resulting in the perfect golden brown onions.
- Season every layer. For a flavorful gratin, you need to season every layer. Use ⅓ of sauce, seasonings, and herbs for every layer.
