How to Make Easy Vegan Green Bean Casserole
Follow these simple steps to prepare this creamy and delicious casserole.
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). Grease a medium-sized baking dish with a little olive oil or vegan butter.
Step 2: Cook the Green Beans
Bring a large pot of salted water to a boil. Add the trimmed green beans and cook them for 4–5 minutes until they are slightly tender but still bright green.
Drain the beans and place them in cold water for a moment to stop the cooking process. Set them aside.
Step 3: Make the Creamy Mushroom Sauce
Heat 1 tablespoon olive oil in a large skillet over medium heat.
Add the chopped onion and cook for about 3 minutes until it becomes soft. Then add the minced garlic and sliced mushrooms. Cook everything together for about 5 minutes until the mushrooms are tender.
Sprinkle the flour over the vegetables and stir well. Slowly add the plant-based milk while stirring continuously. This will help the sauce become smooth and creamy.
Add the soy sauce, garlic powder, onion powder, salt, and black pepper. Let the sauce cook for 3–4 minutes until it thickens.
If you want extra flavor, you can also add nutritional yeast or vegan cheese at this stage.
Step 4: Combine the Green Beans and Sauce
Place the cooked green beans into a large mixing bowl. Pour the creamy mushroom sauce over them and gently mix until everything is well coated.
Step 5: Assemble the Casserole
Transfer the mixture into the prepared baking dish. Spread it evenly using a spoon.
Top the casserole with half of the crispy fried onions.
Step 6: Bake the Casserole
Place the baking dish in the preheated oven and bake for 20 minutes.
After 20 minutes, remove the dish from the oven and add the remaining fried onions on top.
Bake for another 5–10 minutes until the onions become golden and crispy.
Step 7: Serve and Enjoy
Remove the casserole from the oven and let it cool for a few minutes before serving.
The result is a creamy, warm, and crispy vegan green bean casserole that smells amazing and tastes even better.
