Ingredients

• 1 pound fresh green beans, trimmed and cut into 2-inch pieces
• 3 tablespoons unsalted butter
• 8 ounces baby bella mushrooms, finely chopped
• 1 medium yellow onion, finely diced
• 2 large garlic cloves, minced
• 3 tablespoons all-purpose flour
• 1.5 cups whole milk
• 1 cup chicken or vegetable broth
• 0.5 cups heavy cream
• 1.5 teaspoons salt
• 0.5 teaspoons black pepper
• 0.25 teaspoons ground nutmeg
• 1 cup sharp cheddar cheese, shredded
• 1.5 cups crispy fried onions

Directions

Step 1

Preheat your oven to 375°F (190°C) and grease a 9x13-inch baking dish lightly with cooking spray or butter.

Step 2

Bring a large pot of salted water to a boil. Add the green beans and blanch them for 3-4 minutes until tender-crisp. Drain and immediately transfer the green beans to an ice bath to stop the cooking process. Drain again and set aside.

Step 3

In a large skillet over medium heat, melt the butter. Add the mushrooms and onions and sauté for 6-8 minutes until softened and browned. Add minced garlic and cook for another minute until fragrant.

Step 4

Sprinkle the flour over the mushroom mixture and stir to coat. Cook for 1-2 minutes to remove the raw flour taste.

Step 5

Gradually pour in the milk, whisking constantly to prevent lumps. Add the chicken or vegetable broth and heavy cream, continuing to whisk and cook until the mixture thickens, about 3-5 minutes.

Step 6

Season the sauce with salt, black pepper, and ground nutmeg. Stir in the shredded cheddar cheese and mix until melted and fully incorporated.

Step 7

Add the blanched green beans to the skillet and toss them in the cream sauce to coat evenly.

Step 8

Transfer the green bean mixture to the prepared baking dish and spread it out evenly. Sprinkle the crispy fried onions across the top.

Step 9

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

Step 10

Remove from the oven, let sit for 5 minutes, and serve warm. Enjoy the best green bean casserole you’ve ever had!
