Oven-baking oatmeal is a great alternative to stovetop because it's hands-free. It's easy to add in as many extra flavorings (fruit, spices, nuts) as you want. Here, soft apples and cinnamon spice are natural additions to this easy fuss-free baked rendition.

Why this recipe works:

  • Oven baking is a no-fuss, hands-off way to cook oatmeal.
  • Pre-baking the apples ensures that they're cooked through.
  • Granny Smith apples provide tart contrast to the sweet oatmeal.

  • 1 pound Granny Smith apples (3 to 4), peeled, cored, chopped into 1/2-inch pieces
  • 1 1/2 cups rolled oats
  • 1/2 cup walnuts, chopped
  • 1/3 cup plus 3 tablespoons light brown sugar, divided, plus more for serving
  • 1/4 teaspoon salt
  • 1 teaspoon cinnamon
  • 1 large egg
  • 1 3/4 cups milk
  • 2 tablespoons (1 ounce) unsalted butter, melted, plus extra for greasing dish


  1. 1

Whisk 1/3 cup plus 2 tablespoons brown sugar, salt, cinnamon, egg, milk, and melted butter in medium bowl to combine. Pour into baking dish. Using a spoon, gently press and stir oats into milk mixture to moisten and distribute apples evenly.
