Ingredients

• 450 grams fresh green beans, trimmed and halved
• 2 tablespoons olive oil
• 1 medium-sized yellow onion, finely chopped
• 3 cloves garlic, minced
• 230 grams white button mushrooms, chopped
• 2 tablespoons all-purpose flour
• 2 cups unsweetened almond milk (or other plant-based milk)
• 1 cup vegetable broth
• 1 tablespoon soy sauce (or tamari for gluten-free)
• 3 tablespoons nutritional yeast
• 1 teaspoon salt
• 0.5 teaspoons black pepper
• 1.5 cups crispy fried onions (store-bought or homemade, vegan-friendly)

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Bring a large pot of water to boil, then add the green beans. Blanch them for 5 minutes, then drain and transfer immediately to a bowl of ice water to stop the cooking process. Drain and set aside.

Step 3

In a large skillet, heat the olive oil over medium heat. Add the chopped onion and cook for 3-4 minutes until softened and translucent.

Step 4

Add the minced garlic and cook for 1 minute, stirring frequently, until fragrant.

Step 5

Add the chopped mushrooms to the skillet and cook for 7-9 minutes, stirring occasionally, until the mushrooms release their moisture and begin to brown.

Step 6

Sprinkle the flour over the mushroom mixture and stir to coat. Cook for 1-2 minutes, stirring constantly, to eliminate the raw flour taste.

Step 7

Slowly pour in the almond milk and vegetable broth, whisking constantly to prevent lumps. Add the soy sauce, nutritional yeast, salt, and black pepper. Simmer for 4-5 minutes, stirring occasionally, until the sauce thickens.

Step 8

Remove the skillet from the heat and stir in the blanched green beans, ensuring they're fully coated in the creamy mushroom sauce.

Step 9

Transfer the mixture to a 9-inch by 13-inch casserole dish and smooth it into an even layer.

Step 10

Sprinkle the crispy fried onions evenly over the top.

Step 11

Bake in the preheated oven for 20-25 minutes, or until the casserole is bubbly and the onions are golden brown.

Step 12

Allow the casserole to cool for 5 minutes before serving. Enjoy!
