Wholesome Ingredients for This Vegan Green Bean Casserole

Every ingredient in this homemade plant-based green bean casserole serves a purpose: flavor, texture, or nutrition. Here’s a closer look at the key components:

• Fresh mushrooms: These add natural umami and earthy richness. For the best flavor, sauté them until golden and dry to concentrate their flavors.
• Dairy-free sour cream: Creates a creamy texture without the dairy. Use a high-quality brand made from cashews or coconut for rich, tangy results.
• Frozen green beans: Convenient and packed with nutrients. Thaw and pat them dry to ensure they don’t release too much water during baking.
• French-fried onions: A must for that signature crunch on top. Opt for gluten-free varieties if needed.

How to Make Vegan Green Bean Casserole

1. Preheat your oven to 350°F (175°C). Lightly grease a 13×9-inch baking dish and set aside.
2. In a large skillet, heat olive oil over medium heat. Sauté the mushrooms and onions until softened and slightly golden, about 7-10 minutes.
3. Add the minced garlic to the skillet, stirring continuously for 1 minute until aromatic.
4. Stir in the dairy-free sour cream, browning sauce (if using), salt, and pepper. Cook for 2 minutes, then remove from heat.
5. In a large bowl, combine the thawed green beans and shredded dairy-free cheese. Pour the sour cream mixture over the top and stir until coated.
6. Transfer the green bean mixture to the prepared baking dish and spread out evenly.
7. In a small bowl, melt the dairy-free buttery spread. Add the crushed crackers and chopped french-fried onions; mix until evenly coated.
8. Sprinkle the cracker mixture over the casserole, covering it completely.
9. Bake for 25-30 minutes or until the top is golden brown and the casserole is bubbly. Serve hot!
