Introduction

Blueberry Lemon Baked Oatmeal is a bright and comforting breakfast that’s both nourishing and flavorful. Packed with fresh blueberries and zesty lemon, this dish is perfect for a cozy morning or meal prep throughout the week.

A white bowl on a white marbled surface holds a serving of blueberry oatmeal bake. The first layer is a textured mix of baked oats and scattered dark purple blueberries, forming an uneven square base. On top, a smooth dollop of white yogurt spreads across the center. Thin, pale yellow strips of ginger zest are neatly placed over the yogurt. A silver spoon rests inside the bowl, positioned on the left side, partially on the oats. A glass of orange juice and a folded rust-red cloth are placed to the right of the bowl. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

2 cups old fashioned rolled oats
1 teaspoon baking powder
½ teaspoon sea salt
2 cups plant-based milk
¼ cup lemon juice
Zest from 1 lemon
⅓ cup maple syrup
2 tablespoons plain Greek yogurt or vegan yogurt
1 tablespoon ground flaxseed
1 tablespoon melted coconut oil
1 teaspoon vanilla
2 tablespoons poppy seeds
1 ½ cups frozen or fresh blueberries (1 cup for mix-in and ½ cup for topping)
Cooking spray
Toppings: extra blueberries, fresh lemon zest, yogurt, and/or maple syrup

Instructions

Step 1: Preheat the oven to 375°F (190°C) and spray an 8×8 inch square baking dish with cooking spray.
Step 2: In a large bowl, combine the rolled oats, poppy seeds, baking powder, and sea salt.
Step 3: Add the plant-based milk, yogurt, lemon juice, lemon zest, maple syrup, ground flaxseed, melted coconut oil, vanilla, and 1 cup of blueberries to the dry ingredients. Stir well to combine.
Step 4: Pour the oatmeal mixture carefully into the prepared baking dish, spreading it evenly.
Step 5: Scatter the remaining ½ cup blueberries on top of the mixture.
Step 6: Bake for 40 to 50 minutes, until the top is golden and the oatmeal is set.
Step 7: Remove from the oven and let cool for a few minutes before portioning. Serve with extra blueberries, fresh lemon zest, yogurt, and/or maple syrup as desired.

Tips & Variations

For a creamier texture, soak the oats in the milk overnight before baking.
Swap maple syrup for honey or agave syrup if preferred.
Add chopped nuts like almonds or walnuts for extra crunch.
Use fresh lemon zest to enhance the bright citrus flavor without adding bitterness.
Try substituting flaxseed with chia seeds for a different nutrient boost.

Storage

Store leftover baked oatmeal in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave for about 1 minute or until warm. You can also freeze portions for up to 2 months; thaw overnight in the fridge before reheating.

How to Serve

Two bowls on a white marbled surface each contain a baked oat square with visible dark purple blueberries mixed in. The oat squares have a rough, crumbly texture with a golden-brown crust. On top of each square is a thick dollop of white creamy yogurt, covered by thin, pale yellow strips of ginger. Next to the bowls, there is a white rectangular baking dish holding more oat squares with blueberries. Two shiny metal spoons rest on the left side, and there is an orange cloth on the right side near the bowls. Photo taken with an iphone --ar 4:5 --v 7
