Step-by-Step Instructions for Vegan Broccoli Casserole

Steam or boil the broccoli: Steam or boil the broccoli florets until they’re just tender but still firm, avoiding any mushiness. Set aside.
Sauté the onion: In a medium skillet, sauté the diced onion with a splash of olive oil (or water for a WFPB version) until soft and translucent.
Add the mushrooms: Add the oyster mushrooms and a pinch of sea salt. Sauté until the mushrooms are tender.
Deglaze the pan: Pour in the white wine and fresh thyme, and cook until most of the liquid has evaporated.
Prepare the sauce: In a small bowl or blender, whisk together the cashew milk, whole wheat pastry flour, nutritional yeast, onion powder, garlic powder, and sea salt until smooth.
Combine the sauce: Add the cashew milk mixture to the pan with the mushrooms and stir well. Simmer for a few minutes until the sauce has thickened and become creamy.
Add the broccoli: Gently fold the steamed broccoli into the sauce mixture, making sure it’s well coated.
Transfer to a casserole dish: Pour the broccoli mixture into a greased casserole dish, topping with crispy onions, panko breadcrumbs, or crackers.
Broil: Place the casserole under the broiler for a few minutes, or until the topping is golden brown and crispy.
Serve: Serve hot and enjoy!
