Autumn Herbed Vegan Potatoes Au Gratin


I got a mandolin slicer finally! So I wanted to make something fun for the holidays with Thanksgiving coming up. This dinner can be a big challenge to veggies and vegans and also people with food allergies (all my personal categories!). My guide on Mastering Vegan Baking is a place to start for Thanksgiving and other winter holidays but I hope you’ll also enjoy this  Autumn Herbed Vegan Potatoes Au Gratin recipe.

Autumn Herbed Vegan Potatoes Au Gratin

Just like other challenging plant-based recipes, traditional potatoes au gratin rely on cream and butter. When cooking vegan, there are a variety of substitutes but a already prepared vegan butter is one of the easiest subs. Often you’ll also get to use something nut-based and/or some nutritional yeast which has a nice savory/cheesy flavor. Using dried or fresh autumn herbs like thyme, oregano, rosemary and sage adds flavor and complexity to this vegan spin on a classic dish.
