  3. Adjust oven rack to middle position and heat oven to 400 degrees. Combine 2 pounds green beans, trimmed and cut into 1-inch pieces, and ½ cup water in large bowl.

  4. Melt 3 tablespoons butter in 12-inch nonstick skillet over medium-high heat. Add 1 pound cremini mushrooms, sliced thin; 1 tablespoon minced thyme; 2 minced garlic cloves; 1½ teaspoons table salt; and ½ teaspoon pepper and cook until liquid is nearly evaporated, 6 to 8 minutes.

Why This Recipe Works

We jump-start the green beans in the microwave, which means one less thing that has to be cooked on the stovetop. For the sauce, we brown the mushrooms to drive off moisture (to avoid a watery sauce) and develop deep flavor. Adding panko bread crumbs to the traditional fried-onion topping gives it extra crunch and avoids one more pass in the oven to crisp the top, an especially handy thing when oven space is at a premium on Thanksgiving day.
