Vegan Green Bean Casserole Ingredients
For the Casserole
• Olive oil – Perfect for greasing the baking dish; feel free to substitute with non-stick spray for ease.
• Kosher salt – Elevates the dish’s flavor; sea salt can work well if you’re out of kosher.
• Green beans (1½ pounds) – The star of the dish; trim and cut them into 2-inch pieces; French beans can add a fun twist.
• Vegan butter (2 tablespoons) – Adds a creamy richness; for a different flavor, try coconut oil as a substitute.
• Mushrooms (1 pound, sliced) – Provide deep umami flavor and texture; baby bella or white button mushrooms both work beautifully.
• Shallots (2 small or 1 large, chopped) – Bring a touch of sweetness; in a pinch, you can use onions instead.
• Garlic cloves (2, minced) – Infuse the dish with aromatic goodness; if out of fresh garlic, garlic powder can stand in.
• All-purpose flour (2 tablespoons) – Acts as a thickening agent for the creamy sauce; cornstarch is a great gluten-free alternative.
• Non-dairy milk (2 cups, unsweetened soy/oat/almond) – Creates the rich, creamy base; choose one that suits your taste preferences.
• Black pepper – Adds just the right amount of seasoning; swap for white pepper for a gentler kick.
For the Topping
• Fried onions (1½ cups, store-bought) – Bring textural contrast with crispy deliciousness; check that they are vegan-certified for this Vegan Green Bean Casserole.

How to Make Vegan Green Bean Casserole
-
Preheat the oven to 350°F (175°C) and generously grease a 3-quart baking dish with olive oil. This step is essential to prevent sticking and ensure easy serving later.
-
Boil a large pot of water, adding 1 tablespoon of salt. Toss in the green beans and cook for 4 minutes until they are bright green but still crisp. Drain them and rinse under cold water; then, cut into 2-inch pieces.
-
Sauté the mushrooms and shallots in a medium skillet with melted vegan butter over medium heat. Cook for about 5 minutes, until the mushrooms shrink and release their delicious juices, filling your kitchen with an inviting aroma.
-
Add minced garlic to the skillet and cook for an additional 3 minutes, stirring occasionally. You want the garlic to be fragrant but not browned, which will keep its delightful pungency.
-
Mix flour with ¼ cup of non-dairy milk in a bowl to create a slurry. This will help thicken your casserole sauce and make it wonderfully creamy.
-
Combine the remaining 1¾ cups of non-dairy milk into the skillet along with the slurry, kosher salt, and black pepper. Bring this mixture to a gentle simmer, cooking on low for about 4-5 minutes until it thickens to a luscious consistency.
-
Combine the mushroom sauce with the prepared green beans in the greased baking dish. Gently stir until every piece of green bean is coated in that savory mushroom goodness.
-
Top with fried onions and cover the dish with foil. Bake for 20 minutes, then remove the foil and continue baking for another 10 minutes until the onions are golden brown and crispy.
-
Cool for 15 minutes before serving to allow the flavors to meld beautifully. Trust me, this short wait will make each bite even better!
Optional: Drizzle a touch of balsamic glaze on individual servings for a beautiful finish.

Vegan Green Bean Casserole Recipe FAQs
What type of green beans should I use for the casserole?
Absolutely! Fresh green beans are the star of this Vegan Green Bean Casserole. You want them to be vibrant and crisp, so look for ones that are firm to the touch with a bright green color. Avoid those with dark spots, wrinkles, or any sign of wilting. If you can’t find fresh, French beans are a delightful alternative!
How should I store my Vegan Green Bean Casserole leftovers?
For the best taste! Store any leftovers in an airtight container in the refrigerator for up to 3 days. This will keep the casserole flavorful and fresh for your next meal. When you’re ready to enjoy it again, I recommend reheating it in the oven at 350°F (175°C) for about 20-25 minutes for the best texture, covered with foil to maintain moisture.
Can I freeze Vegan Green Bean Casserole?
Yes, you can! If you’d like to prepare in advance, I recommend freezing the casserole before baking. Wrap it tightly in plastic wrap and then in aluminum foil to prevent freezer burn. This will keep it fresh for up to 2 months. When you’re ready to bake, simply thaw it in the fridge overnight and bake at 350°F (175°C) until heated through, about 30-35 minutes.
What can I do if my casserole turns out too soupy?
Very important to keep an eye on that sauce! If you find your casserole is too soupy, make sure to simmer the sauce longer to get it thick enough to coat the back of a spoon before mixing with the green beans. If it’s already combined, you can try adding a bit more flour mixed with a splash of non-dairy milk to thicken it up in the oven.
Are there any allergy considerations to keep in mind for this recipe?
Absolutely! This Vegan Green Bean Casserole is dairy-free, but always check labels on store-bought items like fried onions to ensure they are vegan-friendly. If you have allergies to nuts, be cautious with the non-dairy milk as options like almond milk may not be suitable. Opt for soy or oat milk instead. If cooking for pets, remember that onions and garlic can be harmful to them, so always serve them their own safe treats!
Can I make any substitutions if I don’t have the exact ingredients?
The more the merrier! You can easily adapt this Vegan Green Bean Casserole based on what you have at home. For example, if you don’t have shallots, regular yellow or even red onions can work well. Similarly, you can swap out non-dairy milk types based on your taste preference. Want a rich flavor? Try using cashew cream instead! And don’t hesitate to add in fresh herbs like thyme or rosemary for added flavor!
