How to Make Lemon Blueberry Baked Oatmeal Recipe

Step 1: Prep Your Oven and Dish

Start by preheating your oven to 350ºF. Spray a 10-inch by 7-inch casserole dish with nonstick cooking spray to ensure the baked oatmeal comes out perfectly without sticking. This simple prep sets the stage for flawless baking.

Step 2: Make the Flax Eggs

In a small bowl, combine 2 tablespoons of ground flax seeds with 6 tablespoons of warm water. Stir well and let it rest for about 15 minutes until the mixture thickens into a gel-like consistency. This is the magic that replaces eggs, binding all ingredients beautifully.

Step 3: Create the Fruit Puree

Put the ripe banana, 1 cup pureed blueberries, maple syrup, vanilla extract, and almond milk into a blender or food processor. Blend until smooth and creamy, which adds both flavor and moisture to the oatmeal mix. Pureeing the fruit ensures every bite is bursting with fruity delight.

Step 4: Combine Dry and Wet Ingredients

Transfer the fruit puree into a large mixing bowl. Add rolled oats, white whole wheat flour, baking powder, and a pinch of salt. Stir everything gently to combine. Then fold in the flax eggs, mixing until the batter becomes uniformly thick. Finally, fold in the remaining whole blueberries and lemon zest to add pops of freshness and texture.

Step 5: Bake to Perfection

Pour the batter into your prepared casserole dish, spreading it out evenly with a spatula. Add a few extra blueberries on top for visual appeal and juicy bursts. Place in the oven and bake at 350ºF for 30 minutes or until the oatmeal is set and golden brown on top. The aroma will fill your kitchen with irresistible fruity and lemony scents.

Step 6: Let It Cool and Serve

Allow the baked oatmeal to cool slightly before slicing. This resting time helps it set perfectly for nice, clean servings. Now you’re ready to indulge in a warm, delicious bowl of comfort.

Freezing

You can freeze individual portions for up to 3 months. Simply wrap slices tightly in plastic wrap or place in freezer-safe containers. Thaw overnight in the fridge before reheating for an effortless future breakfast that feels homemade and nourishing.

Reheating

Reheat baked oatmeal slices in the microwave for about 1 to 2 minutes until warm. For a slight crisp on top, pop it in a 350ºF oven for 10 minutes. Add a touch of almond milk or yogurt on the side to refresh the texture and enhance the flavor.

FAQs

Can I use regular eggs instead of flax eggs?

Absolutely! Two large eggs can be used as a direct substitute for the flax eggs if you prefer. They will help bind the ingredients just as well and add a slightly richer texture.

Is this recipe gluten-free?

The recipe as written uses white whole wheat flour, which is not gluten-free. You can swap it with a gluten-free all-purpose flour blend to make the dish gluten-friendly while maintaining tenderness.

Can I substitute frozen blueberries?

Yes, frozen blueberries work fine. Just thaw and drain any excess liquid before pureeing or adding them to the batter to avoid making the oatmeal too watery.

How can I make this recipe vegan?

This recipe is easily vegan by using flax eggs, maple syrup instead of honey, and a plant-based milk like almond milk. It’s naturally free from dairy and eggs when these swaps are made.

Can I add other fruits or nuts?

Definitely! Feel free to incorporate chopped nuts like walnuts or pecans for crunch or swap blueberries for raspberries or blackberries. Just be mindful that baking times might vary slightly with different mix-ins.
