Vegan Potato Bake (Potatoes au Gratin) not only makes a hearty main or side dish for your holiday dinner, but it is also great for your weeknight dinner. Besides, this satisfying dish is really easy to master. Furthermore, this recipe doesn’t contain fancy ingredients and is ready in about an hour.
Of all the ways to cook potatoes, au gratin is maybe my favorite. And if I am in the mood for healthier potatoes au gratin, then this recipe hits the spot perfectly. It is dairy-free, gluten-free, vegan and paleo-friendly. I use cashews, vegetable broth and non-dairy milk to create a rich sauce for this casserole. Sautéing mushrooms, onions, and garlic delivers a flavorful layer, in-between sliced potatoes, zucchini, and dairy-free vegan sauce. The bake is simple to make if you have a mandolin. But if you don’t, then slice the potatoes as thinly as you can with the help of a sharp chef’s knife. Also, make sure that you slice zucchini a bit thicker than potatoes.
To make the Vegan Potato Bake (Potatoes au Gratin), you will need the following ingredients:
Preheat the oven to 355 °F and grease a 10x7-inch baking dish.
In a pan, heat 1 tablespoon olive oil. Add 7 ounces sliced mushrooms and 1 sliced onion. Cook, stirring occasionally, for 4-5 minutes or until lightly browned.
Add 3 cloves minced garlic and cook, stirring, 1 more minute, then set aside.
Drain and rinse 1 cup soaked cashews. In a blender, combine cashews, 1 cup vegetable broth, 1 cup non-dairy milk or water, ½ teaspoon salt, freshly ground black pepper to taste, and 4 tablespoons nutritional yeast if using. Blend for 1-2 minutes until smooth. Pour into a small saucepan and heat through.
Layer half of the sliced potatoes and zucchini in the baking dish.
Top with half of the cashew sauce and spread evenly.
Spread over half of the mushroom-onion mixture.
Repeat the layers and make sure that all vegetables are covered with the sauce.
Bake for about 50 minutes or until the potatoes are tender and soft. You may want to cover the dish with a piece of aluminum foil or parchment paper if it gets too brown on top. Sprinkle vegan cheese on top if using about 5-10 minutes before the bake is done.
Serve garnished with chopped green onions if you wish.
