A Delightfully Cozy Breakfast Idea
Mornings are often rushed and routine. Make them better with a warm, nourishing breakfast that’s as simple as cereal but far more satisfying. This baked oatmeal is sweet, comforting, and easy to prepare ahead. Bake it once, store it in the fridge, and reheat portions throughout the week for quick, flavorful breakfasts.
What You’ll Need
This recipe is a flexible base you can adapt to taste. Swap ingredients to suit your preferences—see the variations section for ideas.
- Oats: Old-fashioned rolled oats work best as the base.
- Brown sugar: Light brown sugar adds sweetness; substitute maple syrup or honey if preferred.
- Pecans: Chopped pecans give texture; walnuts are a good alternative.
- Spices: Cinnamon and a pinch of nutmeg. Pumpkin pie or apple pie spice also work.
- Baking powder: Keeps the bake light (use baking powder, not baking soda).
- Salt
- Eggs: Two eggs help bind the mixture so it bakes up firm.
- Milk: Whole milk gives a creamier result; 2% or skim will also work.
- Vanilla: Pure vanilla extract for best flavor.
- Butter: Melted and mixed into the batter.
- Apples: Firm apples like Honeycrisp and Granny Smith are ideal.
- Blueberries: Use fresh or frozen.
How to Make Blueberry Apple Baked Oatmeal
Prep this on the weekend for easy breakfasts all week. It comes together quickly and bakes into a golden, comforting dish.
- Preheat and prepare: Preheat the oven to 375°F and grease a 9-inch baking dish with butter.
- Mix dry ingredients: In a bowl combine oats, brown sugar, pecans, cinnamon, baking powder, salt, and nutmeg. Whisk to combine.
- Mix wet ingredients: In another bowl whisk the eggs, then stir in the milk, vanilla, and melted butter.
- Combine and assemble: Add the wet mixture to the oats and stir until fully incorporated. Arrange the apples and blueberries in the bottom of the prepared dish, pour the oat mixture over the fruit, and smooth the top.
- Bake: Bake for about 40 minutes, until bubbly and golden. Remove from the oven and let rest for 20 minutes before serving.
Baked Oatmeal Variations
Customize this recipe easily—fruit, milk, and oats are all interchangeable depending on what you have on hand.
- Fruit swaps: Try strawberries, pears, or peeled chopped rhubarb. Avoid very acidic fruits that don’t bake as well.
- Dairy-free: Replace dairy milk with almond, cashew, or coconut milk for a dairy-free version.
- Different oats: Rolled oats are recommended, but steel-cut oats can be used with a longer bake (about 1 hour).
Serving Suggestions
A scoop of baked oatmeal is delicious on its own. For a fuller breakfast or brunch, pair it with simple sides:
- Eggs: Serve alongside a simple omelette or scrambled eggs for added protein.
- Bacon: Oven-baked bacon makes an easy savory side.
- Extra fruit sauce: Top with a spoonful of warm blueberry sauce or a drizzle of maple syrup.
How to Store and Reheat Leftovers
- Refrigerate: Store portions in airtight containers in the fridge for up to 5 days.
- Freeze: Freeze portions in airtight containers or freezer bags for up to 3 months.
- Reheat: Microwave in a microwave-safe bowl for 30-second intervals, stirring until heated through. Alternatively, reheat covered in a saucepan over low heat with a splash of milk or water if needed.
Can I Make Blueberry Apple Baked Oatmeal Ahead?
- Yes. You can bake it ahead and reheat portions, or assemble the casserole, cover it, and bake fresh the next morning.
