How to Make Vegan Green Bean Casserole
Step One: Cook the Green Beans
Bring a large pot of salted water to a boil and cook the green beans until they are crisp-tender. Drain and set aside.
Step Two: Bake the Shallots
Slice the shallots (or red onions) thinly and toss them with olive oil, salt, pepper and bread crumbs on a baking sheet lined with parchment paper. Bake until golden and crispy, stirring halfway through.
Step Three: Make the Mushroom Sauce
In a large skillet, sauté onion and mushrooms until they release their juices and start to brown. Add garlic, thyme, salt and pepper and cook for a few more minutes. Sprinkle with flour and stir well. Then add vegetable broth and miso paste and bring to a boil. Reduce the heat and simmer until thickened. Stir in your favorite plant-based milk for some creaminess.
Step Four: Assemble the Casserole
Spread the green beans in an even layer in a greased baking dish. Pour the mushroom sauce over them and smooth it out. Sprinkle the baked shallots on top.
Step Five: Bake the Casserole
Bake the casserole in a preheated oven at 350°F for 20 to 25 minutes, until bubbly and golden.
Tips and Variations
- You can use any kind of mushrooms you like, such as cremini, shiitake, or chanterelles.
- You can use any kind of plant-based milk you like, such as almond, soy, or oat.
- You can make this casserole ahead of time and refrigerate it without the shallots. Let it come to room temperature before baking and add the shallots just before putting it in the oven.
- You can also make this casserole in stages by cooking the green beans, baking the shallots, and making the mushroom sauce separately. Store them in separate containers in the fridge until ready to assemble and bake.
- You can add some chopped nuts, vegan cheese, or fresh herbs for extra flavor and texture.
