This vegan dauphinoise potatoes recipe with dairy-free cashew cream sauce is the perfect gluten-free side dish for the holiday season! Super creamy and flavourful, vegans and non-vegans alike will swoon over this classic recipe.
There’s something about the holiday season that makes me crave cheesy, creamy potatoes. I knew there had to be a way to satisfy this craving while sticking to my dairy-free diet. Thus, these vegan dauphinoise potatoes were born!
Vegans and non-vegans alike will love this healthy side dish. It’s bursting with flavour from the fresh thyme and dijon mustard. And it gets its creaminess from my secret ingredient — cashews.
Not vegan? These dauphinoise potatoes can easily be made with dairy-based ingredients!
- Cashews (raw, aka not roasted)
- Fresh thyme (can use dried in a pinch)
- Dijon mustard
- Dairy-free milk (I used unsweetened almond milk, but any milk will work.)
- Potatoes (Maris piper works best.)
- Grated cheese (I used vegan, but any mild or sharp cheese will work.)
See recipe card at the bottom of this page for quantities.
Start by measuring out all of the ingredients for the dairy-free cream sauce. Add the cashews, milk, thyme, and mustard to a blender, and blend until completely combined.
Next, prepare the maris piper potatoes. You can slice them with a knife like I did or use a mandolin. You just want them to be roughly the same size and thickness so they cook evenly.
Boil them in a small pot for 3 minutes to soften them before baking.
Next, assemble the vegan dauphinoise potatoes in a prepared casserole dish. Start by adding a layer of potatoes to the bottom of a large baking dish. Then, pour over some of the cashew sauce with a generous sprinkle of the grated cheese and more fresh thyme.
Repeat two more times. (I like to have three layers total, ending with the cheese and herbs.)
Bake at 200C (390F) for 30 minutes until the cheese is golden and the potatoes are cooked through. It should be bubbling around the edges.
Here are a few suggestions for how you can adapt or substitute ingredients:
- More herbs — Instead of or in addition to the fresh thyme, you could use fresh rosemary, parsley, or sage.
- Sweet potatoes — If you prefer sweet potatoes over maris pipers, then you can swap them in this recipe.
A primary reason I love this gluten-free dauphinoise potatoes recipe is because it’s so flexible. I use gluten-free, dairy-free and meat-free ingredients due to allergies and personal choices but you can easily use:
- Bacon — Top with some crispy, crumble bacon or pancetta before serving.
- Dairy — If you’re not vegan or lactose intolerant, then use standard dairy-based ingredients like cream and cheddar cheese.
You’ll need a high-speed blender to make the dairy-free cashew cream sauce, as well as a small pot to boil the potatoes and a casserole dish to bake the completed dish. A standard 9×13 should work well.
These vegan dauphinoise potatoes are a signature side dish that goes well with nearly any main, especially around the holidays. Here are some of my favourite dishes to serve alongside them:
- Easy Lentil Wellington
- Christmas Stuffed Squash
- Orange-Stuffed Trout with Mediterranean Veggies
- Plant-Based Sausage Tray Bake
- Summer Salmon Kebabs
- BBQ Salmon Burgers
If you have a portion of these dairy-free dauphinoise potatoes leftover, simply place in a sealed container in the fridge overnight. You can either reheat in the oven or microwave the next day for lunch or dinner.
Cooked potatoes don’t freeze that well, so eat within a few days of making.
Nope! I prefer fresh when I have them on-hand, but dried works just as well.
Potatoes with waxy peels don’t do well with this recipe. I prefer maris pipers or sweet potatoes so that the sliced potatoes are cooked fully and remain fluffy, even when coated in the dairy-free cheese sauce.
Absolutely! They probably wouldn’t even know this dauphinoise potatoes recipe was dairy-free if you didn’t tell them. It’s a crowd-pleaser!
Truthfully, cashews are the best nut to use in this vegan dauphinoise potatoes recipe’s dairy-free cream sauce. They’re full of delicious and healthy fats and truly come close to real cream in terms of texture and flavor when blended.
