This is a healthier, made from scratch version of the quintessential Thanksgiving casserole.  Made from fresh green beans and mushrooms and savory fried shallots.

Ingredients:
3 cups vegetable oil
6 large shallots, cut into very thin rounds, rings separated
1 1/2 cups all-purpose flour
Coarse salt and ground pepper
2 pounds green beans, trimmed and halved
1/4 cup (1/2 stick) unsalted butter
1 pound button or crimini mushrooms, trimmed and coarsely chopped
14.5 ounces chicken or vegetable broth
1 cup milk

Directions:
Preheat oven to 425 degrees.  In a large skillet, heat oil over medium.  Line a baking sheet with paper towels.  In a large bowl, toss together shallots and 1 1/4 cups flour until shallots are evenly coated.  In batches, shake off excess flour from shallots and fry until golden and crisp, about 5 minutes, adjusting heat if shallots are browning too quickly.  With a slotted spoon, transfer to sheet and season with salt.  Set aside.  (Store in an airtight container at room
temperature with a layer of paper towels underneath, up to 2 days.)

In a large pot of boiling salted water, cook green beans until crisp-tender, 6 minutes.  Drain and rinse with cold water to stop the cooking.  Pat dry.  (To
store, refrigerated in a resealable plastic bag, up to 1 day.)

In a large saucepan, melt butter over medium-high.  Add mushrooms and cook until liquid has evaporated, about 7 minutes.  Season with salt and pepper.  Add 1/4 cup flour and cook, stirring, until incorporated, about 1 minutes.  Whisking constantly, gradually add broth, then milk.  Bring to a simmer.  Cook, stirring occasionally, until sauce thickens, about 5 minutes.  Season with salt and pepper.  (To store, refrigerate with plastic wrap on surface, up to 2 days.
Reheat before using.)

Add green beans to mushroom sauce and toss to coat.  Transfer mixture to a 9-by-13-inch baking dish.  Bake until bubbling around edges, about 15 minutes. Serve topped with fried shallots.  Serves 8
