Cooking Time



For the Casserole:

  • 3/4 cup coconut milk
  • 1/2 cup nutritional yeast
  • 1 cauliflower
  • Salt and pepper, to taste
  • 14 ounces green beans, trimmed
  • 1 onion, diced

For the Topping:

  • 2 handful of gluten-free breadcrumbs
  • 3 garlic cloves
  • Olive oil
  • 1/4 cup nutritional yeast


To Make the Casserole:

  1. Cook cauliflower florets in a steamer in the microwave for around 8 minutes. Or just cook them on the stove, which might take a bit longer. Heat a skillet with a bit of oil or just with vegetable broth, that's up to you. Add onions and green beans and cook them.
  2. When the cauliflower is done, give it into a bowl of a blender or food processor, add coconut milk, nutritional yeast, and season with salt and pepper. Then blend until really creamy and smooth. Don’t worry if you don’t own a blender or food processor you can do it with a potato masher.
  3. Preheat oven to 405°F.

To Make the Topping:

  1. In a small bowl, combine the bread crumbs with a tablespoon of olive oil and one crushed clove of garlic.

To Assemble:

  1. Last, assembling is an easy play as always: start with the green bean mix, followed by the mashed cauliflower, and end with the topping. Bake for around 15 minutes.

  1. Great recipe, but that "405 degrees F" can\’t be right, can it? Since there is virtually no difference between 405 and 400 degrees, I\’m guessing that this is a typo and you actually meant the much more common 450 degrees F (?) Also what size baking dish? From the photo it looks like an 8 x 8 inch?? Thank you!
