Mushrooms and Green Beans Casserole Gluten Free

This casserole features brown (Chestnut) mushrooms and green beans in a deliciously creamy sauce, topped with crispy onions. Tastes amazing on it's own, or on a bed of quinoa. If you can get them, substitute the brown mushrooms for foraged wild mushrooms, such as Pheasant Back's mushrooms. For a quick family dinner, you can leave out the crispy onion topping.

  • Remove from heat. Whisk in the double cream, salt and pepper.
  • To assemble and bake the casserole:
  • Preheat oven to 200 C or 400 F.
  • Spread the fresh raw green beans or lightly thawed green beans evenly over the bottom of a shallow baking dish and pour the mushroom sauce over.
