The perfect potato recipe in one dish
Instead of using several pots and pans to cook everything separately, you can make this creamy and “cheesy” Vegan Potato Bake in just one dish! And the best is, that it’s prepared in only about 10 minutes, and even though you‘ll also have to add in baking time, fortunately, you don’t need to do anything to it while it’s baking in the oven. So you can spend the time doing anything else that has to be done in your household. This is also a reason why my mom loved to make it on busy days after work, by the way.
Easy Vegan Potato Bake
This Potatoes au Gratin is really very easy to make. There are basically two steps required for this recipe. You need only prepare the vegetables (Potatoes, Mushrooms, and Zucchini) and blend up the ingredients for the vegan cheese sauce in a blender, which takes less than 5 minutes. Then you just need to pour the sauce over the potatoes and veggies and put it in the oven for an hour. It couldn’t be easier!
Scalloped Potatoes with Plant-based Ingredients
If you make a traditional dish of Potatoes au Gratin, they usually contain ingredients that aren’t vegan or gluten-free. This healthier dish, however, is made with only plant-based ingredients, so it contains no heavy cream or dairy cheese. The sauce is made of cashews which make the consistency super thick and creamy. I kept the recipe very simple, however, it’s pretty similar to my Vegan Alfredo Sauce.
Vegan Potato Bake with Mushrooms and Zucchini
I love adding healthy vegetables to my meals, so I also added mushrooms zucchini in this Vegan Potato Bake Recipe because they’re perfect for layering with the Potatoes. Also, I like adding pumpkin, tomatoes, spinach, carrots or sweet potatoes. However, you can add any vegetables because it’s a very versatile recipe, so feel free to mix and match to your wish.
This Potatoes au Gratin is:
- Easy to prepare

Vegan Potato Bake (Potatoes au Gratin)
For the Potatoes & Veggies:
- 2 lbs Potatoes (750 g) peeled
- 1 Zucchini (200 g) or sub more potatoes or other veggies
- 7 oz Mushrooms (200 g) optional
- 1 tbsp olive oil
- 1 onion sliced
- 3 garlic cloves minced
Creamy Cashew Sauce:
- 4 tbsp Vegan Cheese optional
- fresh chives optional
- pine nuts optional
- Preheat oven to 355°F (180°C) and grease a baking dish* with a little oil.
Prepare the Veggies:
- Thinly slice zucchini and very thinly slice potatoes. (Zucchini should be sliced a bit thicker than potatoes.) *
- Heat the oil in a large pan. Add onion and mushrooms and fry for about 4-5 minutes, until lightly browned. Add the garlic and cook for another minute while stirring, then set aside.
Make the Cashew sauce:
- Drain and rinse the cashews. Put them into a blender along with non-dairy milk, vegetable broth, salt, pepper, and nutritional yeast. Blend for a few minutes until smooth.
Assemble the Gratin and bake:
- Heat up the cashew sauce in a pot (optionally, to reduce the baking time).
- Spread half of the sliced potatoes and zucchini in the baking dish. Top evenly with half of the cashew sauce, then spread over the onions, garlic and mushrooms. Layer the rest of the potatoes and zucchini, then the rest of the mushrooms and sauce. (Make sure that the veggies are well covered with the sauce).
- Bake the potato bake for about 50 minutes or until the potatoes are fork-tender and soft. (If it gets too brown during baking, cover the dish with tin foil or baking paper. But note that the potatoes need more time to cook through when the dish is covered).
- Optionally, sprinkle vegan cheese over a few minutes before done and continue baking until melted, about 5-10 minutes.
- Garnish with chopped chives and toasted pine nuts or other toppings you like.
- I used a 10x7-inch baking dish and a mandolin slicer for slicing the potatoes and zucchini.
- The bake time may vary depending on how thick you sliced the potatoes or if you covered the dish during baking.
- If you don’t have a blender to blend the cashews, you can use cashew butter (or any other nut butter).
- If you’re allergic to nuts or don’t have any on hand, you can sub coconut cream (the thick part of coconut milk after chilling a can for 24 hours).
