Gluten-Free Green Bean Casserole (Dairy-Free)
This Gluten-Free Green Bean Casserole is my dairy-free take on the classic fall side dish. No need for canned soups here! The creamy, base is made from scratch with coconut milk for creaminess and mushrooms for their fresh flavor. A crispy topping of fried onions completes this comforting dish with a satisfying crunch. Gluten-free, vegan.

Ingredients
- 16 oz (1 pound) frozen haricot vert green beans
- 2 tablespoons olive oil or avocado oil
- ½ medium yellow onion finely diced
- 2 cloves garlic minced
- 8 ounces baby bella mushrooms chopped
- 2 tablespoons arrowroot starch or tapioca starch
- 1 cup canned full-fat coconut milk creamy part only or dairy-free creamer (plain + unsweetened)
- 1 teaspoon dried thyme
- ½ teaspoon dried rosemary
- 1 teaspoon salt
- Black pepper to taste
- ½ teaspoon apple cider vinegar
- 1 cup vegetable broth
- 1 ½ cups crispy gluten-free fried onions
Instructions
- Preheat oven to 375°F. Lightly grease a 2-quart (or 8x8) baking dish. Run frozen green beans under cool water briefly in a colander to remove ice crystals and pat dry.
- Heat oil in a large skillet over medium heat. Add diced onion and sauté 4–5 minutes until softened. Add garlic and mushrooms and cook until mushrooms have released moisture, about 6–8 minutes.
- Sprinkle arrowroot over vegetables and stir to coat. Cook for 1 minute.
- Add coconut milk, thyme, rosemary, salt, pepper, and apple cider vinegar. Stir to combine. Pour in vegetable broth while stirring. Bring to a simmer and cook 3–4 minutes until thickened.
- Place green beans in the prepared baking dish. Transfer mushroom mixture into the baking dish and stir gently to combine.
- Bake for 20 minutes. Remove from the oven and top evenly with crispy fried onions.
- Return to the oven 3-4 minutes to warm the topping. Serve warm.
Notes
Tip: Thin sauce with a splash of broth if it becomes too thick before baking.
