This dairy free green bean casserole from scratch is one of the most delicious holiday classics. It features wild chanterelle mushrooms but it can be adapted with whatever mushrooms are in season: shiitakes, king oysters or baby bellas.
Heat a large skillet over medium low flame and add a drizzle of olive oil. Sautee the onion and a pinch of sea salt until translucent, about 5 minutes.
Whisk together the onion powder and flour with the cashew milk until combined and there are no lumps. Pour into the skillet with the mushrooms and stir.
Bring the sauce to a gentle simmer and cook for a few minutes until thickened up to your liking. Season to taste with sea salt, the nutritional yeast and if desired a fresh squeeze of lemon.
