Step-by-Step Instructions for Vegan Broccoli Casserole

Making this vegan broccoli casserole is simple and straightforward. Follow these steps to create your new favorite dish:

  1. Prepare the Broccoli: Steam or boil the broccoli florets until just tender. They should remain firm, not mushy, so set them aside once they’re done.
  2. Sauté the Onions and Mushrooms: In a skillet, sauté the diced yellow onion until it turns translucent. Add the mushrooms, a pinch of sea salt, and cook until they start to wilt.
  3. Add White Wine and Thyme: Pour in the dry white wine and thyme. Allow the mixture to cook for a few minutes until most of the liquid has evaporated.
  4. Make the Creamy Sauce: In a separate bowl, whisk together the cashew milk, flour, nutritional yeast, onion powder, garlic powder, and sea salt until smooth. Add this mixture to the mushroom-onion pan and simmer until it thickens into a creamy sauce.
  5. Combine the Broccoli: Add the cooked broccoli to the sauce, stirring gently to coat the florets evenly.
  6. Transfer and Bake: Transfer the mixture to a casserole dish. Top with your favorite toppings like crispy onions or panko breadcrumbs. Broil the casserole for a few minutes until the top is golden brown and crispy.
  7. Serve and Enjoy: Serve this delicious casserole hot, and enjoy the comforting, creamy goodness.
