Baked oatmeal is a traditional and comforting breakfast casserole.

Bonus: it can be made ahead of time and reheats beautifully. “FANTASTIC!! I sub peaches during the summer and add ginger and nutmeg. We cut into individual portions and top with Greek yogurt.” What You’ll Need To Make Baked Oatmeal Old-fashioned rolled oats: The base of the dish; don’t substitute instant oats—they won’t give you the same hearty texture. Chopped walnuts or pecans, raisins & apples: These add-ins lend crunch, a touch of chewiness and sweetness, and tart, fruity flavor. Light brown sugar, cinnamon & vanilla: A well-balanced mix that sweetens the oatmeal and adds warm spice and depth of flavor. Baking powder: Helps the dish rise slightly.
