Baked oatmeal transforms everyday oats into a delicious, cake-like breakfast casserole that combines the nutritional benefits of traditional oatmeal with the convenience of meal prep. Unlike stovetop oatmeal, this baked version creates a satisfying texture with crispy edges and a tender center, making it appealing even to those who typically avoid hot cereal. Perfect for busy mornings, this versatile dish can be customized with endless flavor combinations and seasonal ingredients. Rich in fiber, protein, and complex carbohydrates, baked oatmeal provides sustained energy throughout the morning while offering a comforting, homestyle alternative to commercial breakfast options.
How to Prepare Baked Oatmeal
Ingredients:
- 2 cups old-fashioned rolled oats (not quick oats)
- ½ cup brown sugar, packed (or maple syrup/honey)
- 1 teaspoon baking powder
- 1½ teaspoons ground cinnamon
- ½ teaspoon salt
- 2 cups milk (dairy or plant-based)
- 2 large eggs
- 2 tablespoons melted butter or coconut oil, plus more for greasing
- 2 teaspoons vanilla extract
- 2 cups mixed berries (fresh or frozen)
- ½ cup chopped nuts (walnuts, pecans, or almonds)
- Optional add-ins: ¼ cup flaxseed, chia seeds, or shredded coconut
Instructions:
- Preheat and prepare: Heat oven to 350°F (175°C). Grease an 8×8 inch baking dish or 9-inch round cake pan.
- Mix dry ingredients: In a large bowl, combine oats, brown sugar, baking powder, cinnamon, and salt. Stir well.
- Combine wet ingredients: In a separate bowl, whisk together milk, eggs, melted butter, and vanilla extract until well blended.
- Combine and assemble: Pour the wet ingredients into the dry ingredients and mix until combined. Fold in half of the berries and nuts, reserving some for topping.
- Bake: Pour the mixture into the prepared baking dish. Top with remaining berries and nuts. Bake for 40-45 minutes until the edges are golden brown and the center is set but still slightly soft.
- Serve: Let cool for 5-10 minutes before serving. Enjoy warm with a drizzle of maple syrup, a dollop of yogurt, or a splash of milk.
How to Store Baked Oatmeal
Baked oatmeal is perfect for meal prep, with several storage options:
- Refrigeration: Cover the cooled baked oatmeal with plastic wrap or transfer to an airtight container. Store in the refrigerator for up to 5 days. Reheat individual portions in the microwave for 60-90 seconds with a splash of milk to refresh.
- Freezing: For longer storage, cut the cooled oatmeal into individual portions and wrap each piece in plastic wrap. Place wrapped portions in freezer bags or containers and freeze for up to 3 months. Thaw overnight in the refrigerator or reheat from frozen in the microwave for 2-3 minutes.
- Make-ahead option: Prepare the oatmeal mixture the night before, cover, and refrigerate overnight. Add 5 minutes to the baking time when cooking from cold.
- Individual portions: Bake in a muffin tin for 25-30 minutes for grab-and-go breakfast portions that are easier to store and reheat.
