How to Make Vegan Green Bean Casserole
-
Preheat your oven to 350°F (175°C). This ensures that your casserole bakes evenly and reaches that beautiful bubbly texture we all love!
-
Steam the green beans by placing them in a saucepan lined with a steamer basket. Steam for about 5-7 minutes until they’re fork-tender but still vibrant in color.
-
Melt the butter in a large skillet over medium-high heat. Add the chopped baby portobello mushrooms and cook for 5 minutes, stirring occasionally. This will make the mushrooms tender and fragrant.
-
Stir in the minced garlic and continue to cook for another minute until it’s aromatic. Then, sprinkle the flour evenly over the mushrooms, stirring to combine until no dry flour remains.
-
Pour in the non-dairy milk, vegetable broth, and soy sauce. Bring the mixture to a gentle simmer for 5 minutes or until it thickens slightly, creating a creamy sauce.
-
Fold in the steamed green beans and 1/3 cup of the French crispy fried onions. If needed, transfer to an 8×8 inch baking dish. Top with the remaining onions to create a crunchy layer.
-
Bake in the preheated oven for 11-15 minutes or until bubbly and golden brown on top. Let it cool for about 5 minutes before serving to allow the flavors to settle.
Optional: Garnish with freshly cracked black pepper for an extra touch of flavor!

How to Store and Freeze Vegan Green Bean Casserole
Fridge: Store any leftovers in an airtight container in the fridge for up to 3 days. Reheat gently in the microwave or oven, adding a splash of non-dairy milk to keep it creamy.

Reheating: When ready to enjoy, reheat in the oven at 350°F (175°C) for about 20-25 minutes, or in the microwave until heated through.
Shelf Life: Keep in mind that while storing, it’s best to keep the crispy fried onions separate until serving to maintain their crunch!
Expert Tips for Vegan Green Bean Casserole
-
Choose Fresh Beans: Select crisp, bright green beans for the best texture and flavor; avoid limp or yellowed beans to ensure a vibrant casserole.
-
Perfect Thickness: To achieve a creamy sauce, sprinkle the flour evenly and stir well. Stirring helps avoid clumps, giving your Vegan Green Bean Casserole a smooth consistency.
-
Cooking the Mushrooms: Be patient while sautéing the mushrooms. Allow them to brown slightly for a depth of flavor and aroma; rushing might leave them soggy.
-
Don’t Skip the Onions: French crispy fried onions bring an essential crunch to the dish. Ensure you top the casserole with an even layer for maximum texture and taste.
-
Let It Rest: Allow the casserole to cool for about 5 minutes after baking. This resting time helps the flavors meld beautifully and makes for easier serving.
Make Ahead Options
These Vegan Green Bean Casserole preparations are perfect for busy weeknights or holiday gatherings! You can steam the green beans and prepare the creamy mushroom sauce up to 24 hours in advance. Simply steam the beans and allow them to cool before refrigerating, and sauté the mushrooms, garlic, and sauce components, letting them cool before storing in an airtight container. To keep the crispy fried onions fresh, store them separately until ready to bake. When you’re ready to enjoy, combine everything in a baking dish and top with the onions, then bake it for about 11-15 minutes or until bubbly. This way, you’ll have a delightful, stress-free meal that tastes just as delicious as if made fresh!

How should I store leftover vegan green bean casserole?
Storing is easy! Place any leftovers in an airtight container and keep them in the fridge for up to 3 days. When reheating, I suggest adding a splash of non-dairy milk to help restore its creamy consistency—trust me, it makes all the difference!

Very! You can freeze your casserole for up to 3 months. Just make sure to let it cool completely, then transfer it to a freezer-safe container. To reheat, thaw it overnight in the fridge and then pop it in the oven at 350°F (175°C) for about 20-25 minutes until heated through.

To maintain that lovely texture, reheat your casserole in the oven rather than the microwave. Preheat the oven to 350°F (175°C) and cover the dish with foil for the first 15 minutes. Remove the foil for the last few minutes to let the top crisp up again!

Yes, definitely! If you are allergic to soy, you can use tamari or coconut aminos as an alternative to soy sauce.
