How to Make Vegan Green Bean Casserole
-
Preheat the oven to 375°F (190°C). This temperature will ensure your casserole bakes evenly and develops that golden-brown top everyone loves.
-
Chop the mushrooms into small bite-sized pieces. Sauté them in canola oil over medium heat, stirring until they soften and release their savory liquid.
-
Sprinkle 1 1/4 teaspoons of salt over the sautéed mushrooms. Cook until they darken in color, about 5-7 minutes—this will enhance their rich flavor and create a delicious base for your casserole.
-
Add 3 cups of plain flavored plant-based milk, ½ teaspoon of garlic powder, ¼ teaspoon of paprika, and ¼ teaspoon of black pepper to the pan. Stir and heat until the mixture just begins to bubble, then reduce the heat to low.
-
Mix 5 tablespoons of potato starch (or corn starch) with 1 1/2 cups of cold water in a separate container, stirring until fully dissolved. This will be your thickening agent, creating a creamy texture in the sauce.
-
Pour the cornstarch mixture into the hot soup, stirring constantly. Keep stirring until it bubbles and thickens, about 3-5 minutes, then turn off the heat.
-
Layer 32 oz. of green beans in the bottom of a casserole dish. Pour the thickened creamy sauce over the beans and mix well to ensure everything is evenly coated.
-
Sprinkle 1 1/2 cups of fried onions atop the casserole for that irresistible crunch. These will crisp up beautifully in the oven!
-
Bake your casserole for 35-45 minutes, until it’s bubbly and the fried onions are golden brown on top. Your kitchen will smell heavenly during this time!
-
Cool the casserole for about 10 minutes before serving. This helps the layers set and firm up, allowing for easy serving.
Optional: Garnish with fresh herbs for a pop of color and flavor.

Choose Fresh Beans: Opt for fresh green beans when possible. They deliver the best texture and flavor, making your casserole truly shine.

Vegan Green Bean Casserole Recipe FAQs
How do I select the best mushrooms for the Vegan Green Bean Casserole?
Absolutely! When choosing mushrooms, look for firm, plump ones with a smooth surface, free from dark spots or blemishes. Avoid any that feel slimy or look dried out, as these may not deliver the best flavor.
What is the best way to store leftover Vegan Green Bean Casserole?
To store, place your casserole in an airtight container and keep it in the fridge for up to 3 days. Make sure it is covered to maintain its moisture and flavor. If you’d rather prepare it ahead of time, freezing is a great option too!
