Instructions

Preheat the oven to 375°F and prepare a pot of salted boiling water for blanching the green beans.
Blanch the green beans for about 3 minutes, drain, and cool them down.
Sauté the sliced crimini mushrooms until golden, then set aside.
Make the cream sauce by mixing melted butter with flour, then stirring in milk and cream until thickened. Add garlic and Parmesan.
Combine the green beans and mushrooms in a baking dish, pour over the cream sauce, cover with foil, and bake for 25-30 minutes.
Uncover, top with fried onions, and bake for an additional 3 minutes. Let sit before serving.

Notes

Avoid overcooking the green beans for optimal texture.
For a gluten-free option, use cornstarch in place of all-purpose flour.
This dish can be made a day ahead; just assemble it and refrigerate before baking.
