Scalloped Mutton and Tomatoes

The casserole can be assembled up to 4 hours ahead, covered tightly with plastic wrap, and refrigerated. Add 10-15 minutes to the baking time if starting from cold. Do not add the top layer of bread crumbs until just before baking to prevent sogginess.

Store leftovers covered in the refrigerator for up to 3 days. Reheat individual portions in a 350°F oven for 15-20 minutes, or microwave on 50% power to prevent the mutton from toughening. The bread crumb layers will soften upon storage and reheating.
