You definitely don’t need heavy cream, potatoes or grated cheese to make a creamy gratin. This dairy-free Vegetable Gratin is subtly sweet, rich and creamy, and everyone will love it. Layers of sweet parsnips are covered in an easy to make vegan white sauce, sprinkled with vegan parmesan and bread crumbs, then baked to perfection.

- Larger parsnips have a tough, woody core…but it will soften and sweeten in this parsnip gratin recipe, so you can buy any size.

Vegan Gratin Sauce Ingredients
- Cashews: Use raw cashews and soak them in boiling water for a minimum of 30 minutes.
- Nutritional yeast: You can find nutritional yeast at your local grocery store.
- Garlic: Mince garlic cloves or use a microplane zester.
- Olive oil: Helps emulsify this sauce, making it super creamy.For an oil free gratin, substitute with veggie broth.
- Salt and Pepper: Use coarse sea salt and either black pepper or white pepper.
Gratin Topping Ingredients
- Pine nuts: they’re soft and grind up with great texture.
- Hemp seeds: rich in protein, fiber and omega 3s.
- Nutritional yeast: imparts a cheese flavor
- Breadcrumbs: Easily make your own with your favorite bread that meets your dietary needs.
How to make Vegan Parsnip Gratin
Step 1: Make the dairy-free gratin sauce.
Soak cashews in boiling water for minimum of 30 minutes, or up to 4 hours.
Cook grated garlic in olive oil, sprinkled with salt and pepper, over medium heat for about 1 minute, until fragrant. Stir constantly so garlic doesn’t burn.
Drain cashews. Add to blender along with nutritional yeast, garlic mixture and water.
Blend until thick and creamy. It should be pourable. If too thick, add another ¼ cup water and blend again.
Step 2: Make the gratin topping
Add pine nuts, hemp seeds, nutritional yeast, garlic powder and salt to a spice grinder.
Pulse until crumbly. Mixture will resemble parmesan cheese.
Toast a piece of your favorite bread. Break into small pieces and pulse in the spice grinder or food processor until the texture of bread crumbs. Use the same small fry pan and heat one tablespoon olive oil. Add the breadcrumbs and cook, stirring until golden brown.
Step 3: Assemble Parsnip Gratin
Peel parsnips, then trim off the tops and bottoms.
Place sliced parsnips in a large bowl and pour over half the creamy sauce.
Use tongs to mix until all parsnips are coated with sauce.
Arrange half the coated parsnips into the bottom of a casserole dish. Make sure layers of parsnips are evenly dispersed. Drizzle on half the remaining cheese sauce.
Sprinkle with half the crumbly parmesan cheese mixture.
Now add the last layer of parsnip slices. There should be enough parsnips to fill the baking dish. You can take time to make nice looking overlapping rows, or not…it will taste great either way!
Pour on the remaining sauce and then sprinkle with the rest of the parmesan mixture.
Evenly spread the breadcrumbs over the top of the layered parsnips.
Bake in preheated 375 oven on the middle rack for 45-50 minutes. cooking times will vary depending on how thick you sliced the parsnips. The top of the gratin should be crisp and the inside layers should be tender.
Debra’s Pro Tips
- Don’t skip the breadcrumbs…that crisp topping is possibly the best part. It’s easy to make your own as directed, but there’s no shame in buying already made panko to sprinkle on top.
- Make it a parsnip potato gratin recipe by using just a pound of parsnips and the rest potatoes.
- You can add a little sprinkling of nutmeg into the sauce, to bring out all the earthy flavors.
How to Serve and Store
- Serve warm alongside your favorite holiday dishes or as a side dish anytime. I’ve been known to eat leftovers for breakfast as my main dish!
- Store tightly covered in the fridge for up to a week.
- Texture and flavor will suffer in the freezer, I don’t recommend freezing.
- Meal prep: Assemble gratin, but don’t bake. Cover tightly with foil , refrigerate and bake as directed later or the following day.
- Reheat: Cover with foil and heat in 350 oven for 15 minutes, then turn up to 450 for an additional 5 minutes to brown the topping.
