Recipe Instructions
Step 1
Preheat the oven to 350 degrees F (175 degrees C). Fill a large bowl with ice and cold water.
Step 2
Place remaining 5 tablespoons butter in a 2-quart, microwave-safe bowl. Microwave on high power in 30 second intervals, until melted.
Step 3
Bake in the preheated oven until warm and bubbly, about 30 minutes. Top with crispy fried onions and return to the oven for 5 minutes.
Step 4
Bring a large pot of lightly salted water to a boil. Add green beans and cook, uncovered, until crisp-tender, about 6 minutes. Drain in a colander and immediately immerse in ice water for several minutes to stop the cooking process. Drain and transfer to a large bowl.
Step 5
Heat 3 tablespoons butter in a large skillet over medium-high heat. Add onions; sauté until translucent, about 5 minutes. Add mushrooms and garlic; sauté until mushrooms just cooked through, about 5 minutes. Stir into green beans.
Step 6
Whisk flour into melted butter until smooth; season with sea salt and black pepper. Add 1 cup milk; whisk until smooth and combined. Microwave for 2 minutes. Add 1 cup milk, whisking until smooth; microwave for 2 minutes. The roux mixture should thicken between additions, less so as each cup milk is added. Add remaining 1 cup of milk; microwave for 2 minutes more, then whisk until smooth.
Step 7
Transfer green bean mixture to a 9x13-inch baking pan; stir in thickened roux to combine. Season with salt and black pepper.
