Step‑by‑Step Instructions for Vegan Green Bean Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This temperature is perfect for achieving that golden, bubbly finish on your Vegan Green Bean Casserole. While the oven warms up, gather your ingredients and prepare your baking dish for an easy transition once your casserole is ready to bake.

Step 2: Cook the Green Beans
In a large pot, bring enough water to a rolling boil. Carefully add your rinsed and cut fresh green beans and let them cook for about 7-10 minutes, until they are tender but still crisp. Once they are ready, drain the green beans, giving them a gentle shake to remove excess water, and set them aside to cool slightly.

Step 3: Sauté the Aromatics
Heat a generous amount of olive oil in a frying pan over medium heat. Once hot, add the diced onion and sauté for 2-3 minutes until it becomes translucent. Next, stir in the minced garlic and sliced mushrooms, continuing to cook this mixture for an additional 5 minutes until the mushrooms soften and everything becomes aromatic.

Step 4: Create the Sauce Base
Sprinkle the sautéed mixture with salt, pepper, and flour, stirring well to combine. Let this cook for about 2 minutes to ensure the flour is well incorporated and the mixture thickens slightly. This step is crucial for creating the creamy texture in your Vegan Green Bean Casserole.

Step 5: Whisk in Liquids
Gradually pour in the vegetable broth and unsweetened nut milk while whisking constantly. Continue to cook over medium heat, whisking until the sauce thickens, around 10 minutes. You should achieve a rich, creamy consistency that will envelop the green beans beautifully.

Step 6: Combine Ingredients
Once the sauce is thickened, gently fold in one cup of crispy fried onions and the previously cooked green beans. Stir until everything is well-coated in this luscious sauce, adjusting seasoning as necessary. This is where all the flavors come together in your delightful Vegan Green Bean Casserole.

Step 7: Transfer and Top
Pour the mixture into your prepared baking dish, evenly spreading the green bean mixture. Top it generously with the remaining crispy fried onions, which will give your casserole that perfect crunch when baked, enhancing both appearance and taste.

Step 8: Bake to Perfection
Place the baking dish in the preheated oven and bake for about 15-20 minutes, or until the casserole is bubbly and the top is golden brown. For mini casseroles, reduce the baking time to about 8-10 minutes. This final step brings everything together, leaving you with a stunning Vegan Green Bean Casserole.

Expert Tips for the Best Vegan Green Bean Casserole

Plan Ahead: Prepare the homemade condensed cream of mushroom soup a week in advance to save time on the day of serving.

Crispy Onions Note: If you’re making it ahead of time, skip adding the crispy fried onions until baking. This keeps them crunchy and fresh.

Prevent Overcooking: Blanch the green beans just until tender; this preserves their bright color and crisp texture in the Vegan Green Bean Casserole.

Whisking Technique: For a lump-free sauce, whisk constantly while adding the vegetable broth and nut milk to achieve that creamy consistency.

Serving Suggestions: Pair it with a zesty salad or your favorite vegan roast to create a festive, balanced meal that everyone will enjoy!

How to Store and Freeze Vegan Green Bean Casserole

Fridge: Store any leftovers in an airtight container for up to 3 days. Reheat in the oven at 350°F (175°C) until warmed through for best results.

Freezer: You can freeze the assembled casserole by wrapping it tightly in plastic wrap, then aluminum foil, for up to 2 months. Thaw in the fridge overnight before baking.

Reheating: For straight-from-the-fridge casseroles, bake at 375°F (190°C) for about 25-30 minutes, ensuring it’s heated through and the top is crispy again.

Preparation Tips: If preparing ahead, leave off the crispy fried onions until you’re ready to bake the Vegan Green Bean Casserole to maintain their crunch.

Make Ahead Options

These Vegan Green Bean Casseroles are perfect for busy cooks looking to streamline their holiday meal prep! You can prepare the entire casserole up to 24 hours in advance by assembling it without the crispy onions on top. Just cover and refrigerate until you’re ready to bake. This method keeps the green beans fresh and tender, ensuring they remain just as delicious when served. Then, when it’s time to feast, simply pop the casserole in the oven and bake as directed, adding the crispy onions during the last few minutes of baking for that perfect crunch. Enjoy the time-saving benefits and gather around the table with peace of mind!
