For the creamy mushroom sauce:
- 3 tablespoons vegan butter or coconut oil
- 8 ounces white button or baby bella mushrooms thinly sliced
- 4 cloves garlic minced

Cook the green beans
Preheat the oven to 375F. Spray a 9x13 inch casserole dish with nonstick cooking spray and set aside.
Bring a gallon of water and 1 tablespoon of salt to a boil then add the fresh green beans and cook for 2-3 minutes. Drain them right away to stop the cooking process and transfer them to the prepared casserole dish dish and set aside.
Make the french-fried onions
Heat or melt the olive oil or vegan butter in a medium skillet over medium heat. Add the sliced onion and cook until translucent, 2-3 minutes. Transfer the onion to a medium bowl.
Add the almond flour and salt to the same pan and reduce heat to medium-low. Stir constantly for 3-5 minutes to toast the almond flour. It should start to turn a golden-brown color. Be careful not to burn it. Toss the toasted almond flour to the bowl with the onions, toss gently then set aside.
Make the creamy mushroom sauce
Melt the vegan butter or coconut oil to the same pan over medium heat. Once hot, add the mushrooms and cook for 2-3 minutes to soften. Add the garlic and cook for another 1-2 minutes, until it becomes fragrant.
Add the flour or gluten free flour to the mushrooms and garlic and stir well. The flour will coat the mushroom mixture and they should become thick and somewhat clumpy. Add the chicken broth, stirring constantly, then pour in the dairy-free milk and bring the mixture to a simmer over medium-high heat. It should start to thicken well. If it's looking too thick, add a splash or two of milk until it thins out. Stir in the salt and pepper and remove it from the heat.
Assemble and bake
Pour the mushrooms sauce over the green beans and stir well to coat them evenly. Top evenly with the crispy onions.
Bake uncovered for 30-35 minutes or until the top is golden brown and heated all the way through.
