Instructions

First, cut the onion into fine strips or rings. Mix the remaining ingredients into a dough in a bowl, and add the panko bread crumbs in a second bowl. Dip the onion first in the dough and next in the bread crumbs.

Heat the oven to 350 F (175C) and place the onions on a baking tray lined with baking paper. Now bake the onions for about 7 minutes. Repeatedly check to see if they got a nice golden brown color. We do not want to burn them.

In the meantime you can cut mushrooms, onions and beans. You can now steam the green beans for 3 minutes on medium-high heat.

This helps you have a beautiful green bean casserole. Thanks to the steaming, the color will be preserved.

Now sauté the chopped onions and chopped mushrooms in a pan vigorously on medium heat. I always add a sip of water. Take the soaked cashews and blend them with , tapioca starch and nutritional yeast flakes.

If the onions have a nice brown color, you can deg laze them with some white wine or add later the vinegar.

Add the cashew cream and add soy sauce (coconut Aminos), salt and pepper to taste. Let it simmer for around 5 minutes to get a creamy mushroom sauce.

Assemble the classic green bean casserole

Put the blanched green beans in a casserole dish and pour the sauce over them.

You top the casserole with the crispy onions. Bake in the oven at 175 C for about 20 min. If the onions get too dark, cover the casserole

Bring extra flavor into your vegan green bean casserole with some foil.

Hint: If you do not like mushroom pieces in your sauce, you can blend the sauce with the mushrooms to get the cream of mushroom soup. You also want the sauce a little runnier than you used to it. It will thicken even more while baking thanks to the cashews. If it is too thick, you want to add some more non-dairy milk.

Substitution

  • Mushrooms: You can use your favorite mushrooms or a mushroom blend like shiitake mushrooms, cremini mushrooms. The easiest findings in the stores will be white button mushrooms or baby bella mushrooms. All of these will work very well in this version of vegan green bean casserole.
  • Dairy-free Milk: I usually use unsweetened almond milk, because that is what we have at home. You can also use soy milk or oat milk.
  • Cashews: If you do not want to use Cashews, you can also use pumpkin seeds, sunflower seeds. These make a creamy sauce as well. You can also use the Cashew cream with coconut milk.
  • Tahini Butter: We want some kind of fat in the marinade for the breaded onions. Because I do not use vegan butter, I use tahini. You can also use almond butter or cashew butter. You want something that is pretty neutral in taste.
  • Flour: I love to use whole wheat flour or spelt flour instead of all-purpose flour. But you can totally use your favorite gluten-free flour mixture.
  • Soy Sauce: As mentioned before, you can easily switch to tamari sauce for a gluten-free soy sauce alternative. If you want to have it soy free, use coconut aminos.

Variations

  • Smoky Flavor: If you want to add some smokiness to your healthy green bean casserole. You can add a few drops of liquid smoke or 1 teaspoon of smoked paprika powder.
  • Sweet Potatoes: You want to add some color and extra nutrition. What about adding some cubed sweet potatoes to make a healthy sweet potato casserole.

Equipment

You will need the following to make this delicious vegan green bean casserole:

Storage

You can easily prepare this traditional green bean casserole a day or two before you need it. Just top the onions right before you bake it.

  • Fridge: You can easily store leftovers in the fridge. I would store them in an airtight container.
  • Freezing: Do not top the casserole with onions, and freeze the casserole in a casserole dish with an airtight lid.

    Hi Jasmin.
    I made your casserole today and I must say that the recipe was not very clear to follow
    The mushrooms had no measurements so I used a mixture of portobello and white cup mushrooms to approx 150g.
    I didn’t have spelt flour so used whole meal (I’m in Australia) but even so the mixture was way too runny to stick to the onions.
    I did steam the beans prior to making the mushroom sauce which was very runny.
    The recipe didn’t specify so I added the cashews, aminos etc to the onion/ mushroom mixture then added the garlic which was listed in the ingredients but not in the method.
    I baked it all as instructed but the beans were still hard and the sauce way too runny.
    I’d love to get this right so please tell me what I should do.

      Kay, Thank you for your feedback. I do not know why yours where too runny. For the onions: Mine had a pancake dough like consistency. It stuck very well to the onions. Maybe add some more flour. For the casserole: Like in the recipe mentioned you should have blend the cashews, water, yeast flackes and tapioca starch together. And than add to the fried mushrooms. Let it boil, it should thicken. If not you could add some more tapioca starch if you want. I have noticed it was even thicker after baking. I wonder why your green beans are still hard and soft. When I cook / bake green beans they normally do not take longer to be soften than 15-20 min. Have you preheated your oven to 175C?
