This gluten-free and vegan green bean casserole makes for the perfect Thanksgiving vegetable side. Unlike most green bean casserole recipes, it’s healthy, thanks to the fresh ingredients, so you won’t be feeling guilty post-dinner. This standout dish will satisfy even the pickiest of eaters.
There’s no place for canned ingredients in this healthy green bean casserole recipe. Canned green beans not only contain BPA but also are lacking nutrients. Cooking fresh green beans is far healthier and worth the extra few minutes cook time.
We’ve also skipped the canned cream of mushroom soup that’s often used in green bean casserole recipes. Instead, this vegan green bean casserole recipe uses cashew cream. Cashew cream is a great substitute for heavy cream in vegan dishes. It’s far less heavy and won’t leave you with a stomach ache.
The key to making your green bean casserole extra tasty is in the topping. Crispy fried onions add a delicious crunch. In this recipe, the onions get mixed with gluten-free flour and arrowroot to create a crispy coating. Then, they are very lightly fried in safflower oil which makes them golden brown. Even though they are lightened up, they are just as tasty!
You may notice that this is lacking a very common green bean casserole ingredient: mushrooms. They are optional in case you have a mushroom-hater at your Thanksgiving table which is quite common given mushrooms tend to be a “love it or hate it” type of food. But if all of your guests are pro-mushrooms then feel free to add them.
Vegan Green Bean Casserole Recipe
- For the casserole:
- 1 pound of green beans, rinsed and trimmed
- ⅔ cup cashews, soaked for 8 hours and drained
- 1 cup unsweetened almond milk
- 1 teaspoon sea salt
- Optional: ½ cup chopped crimini mushrooms
- For the topping:
- 1 large yellow onion, sliced thinly into half-moon slices
- 1-2 cups unsweetened almond milk
- ½ cup gluten-free all purpose flour
- ¼ cup brown rice flour
- ⅓ cup safflower oil
- 2 teaspoons arrowroot powder
- 1 teaspoon sea salt
- Add the onions to a bowl and add enough almond milk to cover them. Let soak for 15 minutes and then drain.
- Heat the safflower oil in a deep skillet over medium heat.
- Add the gluten-free all-purpose flour, brown rice flour, arrowroot powder, and sea salt to a medium bowl. Whisk until well combined. Add the onions and stir until onions are completely coated.
- Add the coated onions to the skillet with minimal overlap. Let cook for about three minutes and then gently flip them. Cook for another three minutes, or until the onions are golden brown. Transfer to a paper towel.
- Preheat the oven to 350 degrees Fahrenheit. Lightly grease an 8x8 baking dish or cast iron skillet with olive oil. Bring a large pot of salted water to boil. Add the green beans and boil for five minutes. Drain into a colander and then transfer to a large bowl filled with ice water. Let sit for about one minute and then return to the colander to drain.
- Meanwhile, add the almond milk, sea salt, and cashews to a high-speed blender. Blend for about two minutes, until completely smooth.
- Add the green beans to the prepared baking dish. Pour the cashew cream over the green beans. Top with crispy onions then bake in the oven for about 20 minutes.
- Serve immediately and enjoy!
