Ingredients for making Vegan Potatoes au Gratin

Ingredients for vegan potatoes au gratin in bowls (potatoes, soy cream, vegan butter substitute, salt, pepper and nutmeg)
  • Potatoes
  • Vegan cream substitute (I used soy cream)
  • Vegan butter substitute
  • Nutmeg
  • Salt & pepper
  • Optional: A clove of garlic, nutritional yeast, or thyme

This recipe is as simple as it gets. It only needs five pantry-friendly ingredients. The star of the dish is the potato. I recommend using delicious hard-boiling potatoes. They will keep a nice texture when baking them. Yukon gold or Russet potatoes are fantastic choices for vegan gratin au potatoes. Regarding vegan cream, I opted for a full-fat soy cream for lots of flavor. For the vegan butter substitute, I used a version with a nice, mild flavor without that distinct margarine taste to it. I’d recommend going with any brand you’d otherwise like for cooking. Regarding spices, salt, pepper, and nutmeg are all this dish needs. You can use a clove of garlic to rub down the casserole form for some extra flavor.

While traditional gratin au potato features cheese, this recipe tastes perfectly without it. Optionally, you can add nutritional yeast for some extra cheesy notes or some thyme, but this recipe works perfectly as simple as it is. 🙂

How to make Vegan Potatoes au Gratin

Slicing potatoes with a mandoline slicer on a wooden cutting board

Making this dish is super easy. It only involves a little bit of preparation work. Using a mandoline makes the process of making this dish a whole lot easier! Firstly, let’s peel our potatoes. Next, slice the potatoes into thin, uniform slices. Having the slices even and thin is crucial for this dish to ensure the potatoes are becoming soft when baking. Next, take your casserole. Rub it down with a sliced clove of garlic and give it a good greasing with the vegan butter substitute. You can already preheat your oven to 180° C (355° F).

Layering the Potatoes and Cream:

Now, you can start with alternating one layer of potatoes before putting on a layer of vegan cream. The potatoes also can overlap a bit. Repeat this process until the casserole dish is filled to the top. Season with some salt. Optionally, you can sprinkle in some nutritional yeast for an extra cheesy kick. To give this dish a nice crust, we will add some flakes of the vegan butter substitute. Scrape off some vegan butter substitute using a fork or knife and sprinkle it over the final layer of potatoes. Season with nutmeg, salt & pepper.

You can allow the dish to set for about 15 minutes before digging in.

I love pairing this potato grating with some protein and veg. Last time, I served it with some simple braised red cabbage and this vegan lentil stew, to which I added some more winter spices and chestnuts. It was a perfect dinner!
