Vegan green bean casserole is a great-tasting makeover of the traditional version of this classic Thanksgiving side dish recipe. Everyone will love the crisp green beans, homemade mushroom sauce, and baked crispy onions in this dairy-free green bean casserole when you serve it up for dinner this year.
Slice the onions into thin rings, about ⅛ inch or thinner. Separate the rings and place in a bowl. Add almond milk and mix around to coat completely.
1 large sweet onion, ½ cup soy or almond milk
In a large bowl mix together flour, panko, smoked paprika, salt and pepper. Stir well until all the ingredients are fully combined. Transfer the onions from the liquid to the flour mixture one handful at a time. Use your hands to toss the onions coating all the pieces entirely.
¼ cup all-purpose flour, 2 tablespoons panko breadcrumbs, ¼ teaspoon smoked paprika, ½ teaspoon salt, ¼ teaspoon black pepper
Lay the onions in a single layer on a baking sheet lined with parchment. Place into a 425 degree oven and bake for 15-20 minutes or until browned and crunchy. Move and turn onions at five minute intervals so that all the sides of the onion get browned.
Make mushroom sauce
Heat grapeseed oil in a medium saucepan over medium-high heat. When hot, add the garlic and cook for 60 seconds. Stir in the flour until a well-mixed paste is formed.
Add mushroom broth and coconut milk, continue stirring with a whisk. Add the miso and stir it in well. Add mushrooms and thyme, reduce heat to low and cook until sauce thickens, stirring occasionally.
½ cup coconut milk, 1 ½ cup mushroom broth, 2 cups fresh mushrooms, 2 teaspoons fresh thyme, 1 tablespoon white miso, Salt and black pepper
If the sauce isnt thick enough you can mix cornstarch with a bit of water and add it to the sauce. Cook for a bit longer to give it time to thicken.
1-2 tablespoons cornstarch
Steam green beans
Fill a large pot with water halfway and place over medium high heat. When the water boils, crop the beans into the water and cook for 1-2 minutes. Immediately drain and place beans in cold water to cool them.
1 pound fresh green beans
Assemble dish
Add the green beans to an oven safe bowl or casserole dish and top with sauce. Finish off the dish with the crispy onions. Bake in the oven at 350° F for 15-20 minutes or until heated through.
Notes
Be sure to check out the full post above for more tips about the ingredients, serving tips, how to store, and much more.
Don’t cook the green beans too long when blanching them. They should be crisp and tender since they will cook more in the oven.
Slice the onions evenly. This will ensure they cook in the same amount of time in the oven.
Want a thicker sauce? Add cornstarch to the sauce if you prefer a thicker mushroom sauce. Mix 1 tablespoon at a time with a bit of water and then stir into the pot. Let it cook for a few minutes to see if it thickens. Repeat as needed until desired consistency is reached.
Use canned coconut milk for the best results when making the creamy mushroom sauce. Other non-dairy milk s simply have the same result.
