Baked oatmeal is one of my favorite winter breakfasts. It’s mixed by hand in one bowl and you can prep the ingredients the night before.

I don’t like my breakfast to taste like dessert, so I use just enough maple syrup for a lightly sweet taste. An apple adds a little more sweetness and some moisture.

If you like your oatmeal sweeter you can add up to a 1/2 cup of white or brown sugar to the recipe.

Ingredient Notes

  • Rolled Oats– Old fashioned rolled oats give the oatmeal a nice chewy texture. Quick cooking oats can be used, but they will break down into smaller bits and the oatmeal will have a mushier texture.
  • Apple – Any type of apple will work for this recipe.
  • Milk – You can use any type of milk for this recipe; whole milk, lowfat milk, buttermilk or non-diary milk.
  • Walnuts – Are classic with apples, but you can use any nut or leave them out all together.
  • Maple Syrup -I add just enough for a lightly sweet flavor. If you like your oatmeal sweeter you can add up to a 1/2 cup of white or brown sugar to the recipe. You can also substitute honey for the syrup.
  • Butter – To make the recipe vegan, you can use non-dairy margarine or oil.
