Ingredients Equipment Method Notes

Ingredients
  

  • 2 cups rolled oats preferably old-fashioned
  • 1 cup milk dairy or plant-based
  • 1/4 cup brown sugar packed
  • 1 teaspoon ground cinnamon
  • 0.5 teaspoon vanilla extract
  • 1 large egg lightly beaten
  • 2 medium apples peeled, cored, sliced
  • 1/4 cup chopped nuts optional, like walnuts or pecans
  • 1 tablespoon unsalted butter melted, for greasing

Equipment

  • Mixing Bowl
  • Baking Dish
  • Wooden spoon or spatula
  • Measuring cups and spoons
  • Knife
  • Cutting board

Method
 

  1. Preheat your oven to 375°F (190°C) and grease a baking dish with melted butter for a non-stick surface.
  2. Slice the apples into thin, even pieces and set aside. These will add juicy sweetness and a tender texture to the baked oatmeal.
  3. In a large mixing bowl, whisk together the rolled oats, brown sugar, ground cinnamon, and a pinch of salt if desired. Stir until well combined, creating an aromatic base.
  4. Pour the milk into the dry mixture, then add the lightly beaten egg and vanilla extract. Fold everything together with a spatula until the mixture is creamy and slightly thickened.
  5. Add the sliced apples to the mixture, gently folding them in to distribute evenly. The apple slices will become tender and slightly caramelized during baking.
  6. Pour the batter into the prepared baking dish, spreading it out evenly with a spatula so the surface is smooth.
  7. If using nuts, sprinkle them evenly over the top for added crunch and flavor.
  8. Bake in the preheated oven for 30-35 minutes, or until the top is golden brown and the mixture is set around the edges with a slight puff in the center.
  9. Remove the baked oatmeal from the oven and let it cool slightly for about 5 minutes — it will be soft but hold its shape beautifully.
  10. Serve warm, perhaps with a drizzle of honey or a dollop of yogurt, to enjoy the crispy edges and tender apple-filled center together.

Notes

You can prepare this the night before for an even easier morning, just cover and refrigerate, then bake the next day.
