I’ve created an easy vegan gluten-free green bean casserole as part of Kin’s Ultimate Thanksgiving Menu collaboration! So there you go! No need to fret about cooking this years feast, as our fellow Kin creators got together to bring you lots of great recipe ideas. Check out our video below or keep scrolling for the full recipe!

This is a great way to get in your greens and enjoy it, too! Plus, those crispy onion strings are slightly addictive. Don’t say I didn’t warn you! I’ve also made a similar recipe with crispy pesto onions on top, using store-bought vegan pesto and alfredo sauces. Check that recipe out here.

crispy onion strings

  • 1 white onion
  • 1 1/2 C nondairy milk (soy or almond work best)
  • 1 tbsp apple cider vinegar
  • 1 1/2 C rice flour
  • 1 tsp smoked paprika
  • 1 tsp sea salt
  • 1/2 tsp ground black pepper
  • 3 C vegetable oil (for frying)

green bean casserole

  • 8 C fresh green beans (or thawed frozen green beans)
  • 1 C raw whole cashews, soaked for 20 minutes in hot water
  • 1 1/2 C water
  • 1 tbsp arrowroot flour or cornstarch
  • 1 tbsp coconut oil
  • 8 oz cremini mushrooms
  • 1 shallot, finely chopped
  • 2 garlic cloves, minced
  • 1 tsp onion powder
  • 1/2 tsp nutmeg
  • 1/2 tsp sea salt
  • 1/2 tsp ground black pepper
  • 2/3 cup low-sodium vegetable stock
  • 1 tbsp lemon juice


  1. Thinly slice the onion with a mandolin, or if you're great with a knife, try it out! They should be thin enough that you can see through them.

  2. Pour the nondairy milk into a bowl and whisk in the apple cider vinegar. Let the onions soak in this mixture for 10 to 15 minutes.

  3. In a separate mixing bowl, combine the flour with smoked paprika, sea salt, and ground black pepper.

  4. Heat your frying oil in large pot until it reaches 365°F.

  5. Using your hands, toss and coat all the onions with flour. Gently shake off any excess and set them aside in another bowl. Deep fry onions in small batches. They take approximately 2 minutes. Remove with tongs and lay out onto paper towel. Continue doing batches until all the onions are used up.

  6. If you have more onions than you need to top the one casserole, just bring the extras to the table as I'm sure people will be topping their entire plate of food with these delicious, crunchy onions!

  7. To make the sauce for the casserole, drain the cashews from the soaking water. Rinse them under fresh water and drain. Then add to a high-powered blender with fresh water and arrowroot flour. Blend until very smooth.

  8. Heat coconut oil in a large pan over medium heat, add mushrooms and sauté for 2 minutes.
  9. Add shallot and sauté for another 3 to 5 minutes.

  10. Add minced garlic and sauté for another minute. Then add nutmeg, onion powder, sea salt, and ground black pepper and sauté for 2 to 3 minutes.

  11. Stir in low-sodium vegetable stock and cashew cream in small portions, bit by bit, stirring constantly until smooth and well combined. Bring to a simmer.

  12. Once the sauce is simmering, add lemon juice and then green beans. Toss the beans in the sauce and cover the pan with a lid.

  13. Let this sit for 20 minutes stirring occasionally until the beans are cooked, but still bright green and slightly crisp.
  14. Remove the pan from the heat and either serve it in the pan or transfer beans and sauce to a casserole dish. Top with crispy onions. You can also put the whole casserole under the broiler for a few minutes to warm and crisp up the onion strings. Serve immediately!

    1. you could make the sauce with the mushrooms and everything, just leave out the beans. Then re-heat it just before. have the green beans blanched and sitting in the fridge to just stir in and cook a little more with the reheating sauce. But the onions are best when done just before so they’re crispy!

  1. My mom always made green bean casserole for Thanksgiving as her dish and I love that stuff. She used canned green beans though which give it a different flavor. Now that I’m vegan I’ve been looking for a way to recreate the cream of mushroom soup so that I can still eat my favorite food. Thank you 🙂

  2. I am having trouble finding arrow root flour. Is there another option you recommend? Also can I just use another GF four for the onion ornis rice the best?

  3. I made this for Thanksgiving this year and it was absolutely delicious! I love the sauce (particularly the nutmeg in it) so much that I plan to make it to serve on pasta sometimes. 🙂
