Warm and comforting, this blueberry baked oatmeal is a wholesome and nutritious breakfast! It will quickly become your go-to baked oatmeal recipe.
Baked oatmeal is one of those breakfasts that feels like a cozy hug in bowl form — warm, satisfying, and easy to prepare ahead. I still love it years after first making it. While it does need time in the oven, it’s perfect for quiet weekend mornings or when you want a comforting start to the day. This version uses fresh blueberries that burst and become syrupy as they bake, adding a lovely sweet-tart contrast to the hearty oats.
What is baked oatmeal?
Baked oatmeal is exactly what it sounds like: oats combined with liquid, an egg to bind (or a substitute for vegan versions), a sweetener, and flavorings, then baked until set. The texture is somewhere between a firm porridge and a soft cake — chewy, tender, and easy to slice and serve. It’s ideal for feeding a family or for meal-prepping breakfasts that reheat well during the week.
What do you need to make blueberry baked oatmeal?
This recipe relies mainly on pantry staples and fresh fruit. Fresh blueberries are best because they retain a bright flavor and texture after baking, but frozen berries can be used as well. You’ll need the following:
- 2 cups large flake rolled oats
- 1 tsp baking powder
- 1/2 tsp ground cinnamon
- 1/2 tsp salt
- 1/3 cup honey (or maple syrup as an alternative)
- 1 egg (or a flax egg for vegan)
- 2 tbsp melted butter (or coconut oil for vegan)
- 1 1/2 cups almond milk (or any milk of choice)
- 1 tsp pure vanilla extract
- 1 cup fresh blueberries (or frozen, added straight from the freezer)
- Optional: whipped cream or yogurt for topping
How do you make this blueberry baked oatmeal?
- Preheat the oven to 350°F (175°C). Lightly grease an 8 x 8-inch baking dish with nonstick spray or a little melted butter.
- In a large bowl, whisk together the oats, baking powder, cinnamon, and salt.
- In a separate bowl, whisk the honey, egg, almond milk, melted butter, and vanilla until combined.
- Pour the dry ingredients into the wet ingredients and stir just until combined. Fold in the blueberries gently so they don’t burst too much while mixing.
- Transfer the mixture to the prepared baking dish and spread it into an even layer. Bake for 25–30 minutes, or until the center is set and the top is slightly golden. A gentle shake of the dish should show very little jiggle.
- Remove from the oven and let cool for 5–10 minutes before slicing. Serve warm with a dollop of whipped cream, yogurt, or a drizzle of maple syrup if desired.
Can this recipe be made vegan?
Yes. Swap melted butter for coconut oil and replace the egg with a flaxseed “egg” (1 tbsp ground flaxseed mixed with 3 tbsp water, set for a few minutes to thicken). Use maple syrup instead of honey, and any plant-based milk works in place of almond milk. The texture will be slightly different but still delicious and satisfying.
Storage and make-ahead tips
Leftovers keep well. Once the baked oatmeal has cooled to room temperature, store it in an airtight container in the refrigerator for 3–4 days. Reheat individual portions in the microwave for about 30–60 seconds or warm gently on the stovetop with a splash of milk to loosen the texture.
You can also freeze portions for longer storage. Cut into squares, place in an airtight container or freezer bag, and freeze for up to 2 months. Thaw overnight in the fridge before reheating, or warm directly from frozen in a low oven or microwave.
Variations, tips, and serving ideas
- Swap blueberries for other berries, chopped apples, diced pears, or sliced bananas for different flavor profiles.
- Add a handful of chopped nuts or a sprinkle of seeds on top for extra crunch and nutrition.
- Stir in a spoonful of peanut butter, almond butter, or dark chocolate chips before baking for a richer treat.
- If you prefer a sweeter bake, increase the honey or maple syrup by a tablespoon or two, or add a touch of brown sugar.
- To make smaller or larger batches, multiply ingredient quantities and bake in a larger dish; baking time may vary slightly.

Final notes
If using frozen blueberries, fold them in directly from frozen so they keep their shape better during mixing. Let the baked oatmeal rest a few minutes after it comes out of the oven — it firms up as it cools, making it easier to slice. This recipe is versatile, wholesome, and ideal for busy mornings when you want a warm, nourishing breakfast ready to enjoy.
