- 1/4 teaspoon pepper – Introduces a mild heat and depth to the flavor profile.

The Process for Making Dairy Free Vegan Green Bean Casserole

Making this Dairy Free Vegan Green Bean Casserole is a rewarding experience that fills your kitchen with delicious aromas. Follow these steps to create a dish that will impress everyone!
- Preheat your oven to 350°F. This step is crucial as you want your casserole to bake perfectly without any cold spots.
- In a medium bowl, fill it with 1/2 cup of almond milk (the one you reserved from the fried onions) and add the thinly sliced onion. Make sure to separate all the rings so they soak up that creamy goodness while you prepare the rest of the casserole.
- In a large frying pan, heat 1 1/2 tablespoons of avocado oil over medium-high heat. You want it hot enough to sauté but not smoking. Add in the sliced mushrooms and diced onion, and cook them until they are lightly golden brown, which should take about 3 to 4 minutes.
- While those are cooking, fill a large pot with water, adding a pinch of salt, and bring it to a boil. Once boiling, add in the trimmed green beans and cook until they are fork-tender, which should take about 7 to 8 minutes. Drain the beans and place them on a paper towel-lined plate to absorb any excess water.
- Once your mushrooms and onions are golden, add in 1 cup of almond milk and 1 cup of coconut milk (make sure to reserve the rest for later), along with the sea salt and pepper. Stir until everything is well combined, letting those flavors meld together.
- Bring the mixture to a boil. While you’re waiting, whisk together 2 tablespoons of tapioca starch and the remaining 1 tablespoon of each milk in a small bowl until it’s nice and smooth.
- Once the sauce is boiling, stir in the tapioca and milk mixture, stirring constantly. Allow the milk mixture to boil for about 4 minutes while you stir to prevent it from sticking to the pan.
- Reduce the heat to medium and let the sauce simmer, stirring frequently, until it thickens and reduces by half. This should take about 10 to 11 minutes. You want it to be really thick for that perfect casserole consistency.
- After the sauce has thickened, gently fold in the green beans, making sure they are evenly coated with the creamy mixture.
- Pour the mixture into an 8Ă—8-inch baking dish, spreading it evenly. Bake in the preheated oven until the sides are bubbly and the sauce has thickened further, around 25 minutes.
- While the casserole is baking, it’s time to prepare the crispy onions. Heat 1/2 cup of avocado oil in a medium saucepan over medium-high heat, then reduce to medium. You want it hot enough that it sizzles when you add the onion, but not so hot that it burns.
- In a large Ziploc bag, combine 2 tablespoons of tapioca starch, 2 tablespoons of coconut flour, salt, and pepper. Drain the onions soaking in the almond milk, transfer them to the bag, and shake gently to coat each ring evenly.
- Carefully drop a few onion rings into the hot oil, ensuring not to overcrowd the pan. Fry until they are lightly golden brown and crispy, flipping as necessary. I usually do this in 4 batches to get them just right.
- Once cooked, transfer the crispy onions to a paper towel-lined plate to blot off any excess oil. Repeat this process until all the rings are done.
- When the casserole is finished baking, scatter the fried onions on top, pressing them lightly into the mixture. Bake for an additional 5 minutes, then serve and enjoy!
Things Worth Knowing
- Texture Matters: The key to a great casserole is the contrast in textures. The creamy sauce, tender green beans, and crispy onions create a delightful experience.
- Preparation is Key: To save time, prep your ingredients ahead of time. Slice the onions and mushrooms, and trim the green beans before you start cooking.
- Don’t Rush the Sauce: Allowing the sauce to thicken properly ensures the casserole won’t be watery. Patience is crucial here!
- Quality Ingredients: Use fresh ingredients for the best flavor. Fresh green beans will always outperform canned, both in taste and nutrition.
- Experiment with Toppings: Feel free to get creative with the topping. Try adding crushed nuts or seeds for an extra crunch!
