  Add 2 Tbsp butter and 2 sprigs of thyme to the pan. Cook, tossing occasionally, until butter browns and mushrooms are dark brown and very tender, about 4 minutes longer. Season with salt and transfer to a plate. Repeat with 2 Tbsp butter, salt and remaining oil, mushrooms, and thyme.

  Melt remaining 2 Tbsp butter in a large saucepan over medium-low heat. Whisk in flour and cook, whisking occasionally until roux is golden brown and smells nutty, about 4 minutes. Whisk in milk and cream.

  Increase heat and bring to a simmer, whisking often, and cook until sauce is thick and bubbling, about 5 minutes. Remove from heat and whisk in garlic and parmesan. Season with salt and pepper.

  Arrange pulled pork, green beans, and mushrooms in a 2 quart baking dish. Pour sauce over.

  Cover tightly with foil and bake until sauce is bubbling, about 25-30 minutes. Uncover and continue to bake until casserole is lightly browned on top and around the edges, about 15-20 minutes longer.
