Preparation
- Preheat the oven to 400˚F (200˚C).
- In a large pot of salted boiling water, blanch the green beans for 3 minutes, until tender and bright green. Drain and transfer to a 9x13-inch (23x33 cm) baking dish.
- Melt 4 tablespoons of butter in a large pan over high heat. Add the onions and cook for 8 minutes, until softened and translucent.
- Add the mushrooms and cook for 5 minutes, until browned. Add the garlic and cook just until fragrant, about 1 minute.
- Transfer the vegetable mixture to the casserole dish with the green beans. Wipe out the pan.
- Melt the remaining 4 tablespoons of butter in the same pan. Add the flour and stir to combine. Cook until a golden brown roux forms, for 5 minutes.
- Add the milk, heavy cream, salt, pepper, chicken broth, and Parmesan cheese, and stir to combine. Reduce the heat to medium-low and cook until the sauce is thickened, about 10 minutes.
- Pour the sauce evenly over the vegetables in the casserole dish and toss until everything is well coated. Cover with foil.
- Bake for 20 minutes, then remove the foil and bake for another 10 minutes.
- Top the casserole with the fried onions, then serve.
- Enjoy!
