Ingredients

• 500 grams Fresh green beans, trimmed
• 2 tablespoons Olive oil
• 1 medium Yellow onion, finely chopped
• 3 cloves Garlic, minced
• 3 tablespoons All-purpose flour
• 500 ml Vegetable broth
• 250 ml Unsweetened almond milk (or any non-dairy milk)
• 1 tablespoon Soy sauce
• 2 tablespoons Nutritional yeast
• 1 teaspoon Salt
• 0.5 teaspoons Black pepper
• 100 grams Store-bought crispy fried onions (or homemade)

Directions

Step 1

Preheat your oven to 190°C (375°F).

Step 2

Bring a large pot of water to a boil and season it with a generous pinch of salt. Blanch the green beans for 5 minutes, then drain and immediately transfer them to a bowl of ice water. This stops the cooking process and keeps the beans vibrant green.

Step 3

In a large skillet, heat the olive oil over medium heat. Add the chopped onion and cook until softened and lightly golden, about 5-7 minutes.

Step 4

Add the minced garlic to the skillet and sauté for another 1-2 minutes, stirring frequently.

Step 5

Sprinkle the flour over the onions and garlic, stirring constantly, to form a paste. Cook for 1-2 minutes to eliminate the raw flour taste.

Step 6

Gradually pour in the vegetable broth, whisking continuously to avoid lumps. Then, add the almond milk and stir until the mixture thickens, about 4-5 minutes.

Step 7

Add the soy sauce, nutritional yeast, salt, and black pepper to the gravy. Stir to combine, then remove the skillet from the heat.

Step 8

In a large mixing bowl, combine the blanched green beans with the onion gravy. Mix until the beans are well-coated.

Step 9

Transfer the green bean mixture into a lightly greased 9x13-inch casserole dish. Spread it out evenly.

Step 10

Sprinkle the crispy fried onions evenly over the top of the casserole.

Step 11

Bake for 15-20 minutes, or until the casserole is bubbly and the fried onions are golden brown. Keep an eye on the onions to make sure they don’t burn.

Step 12

Remove from the oven and let cool for 5 minutes before serving. Enjoy your delicious Vegan Green Bean Casserole!
