Ingredients

Scale

Dry Ingredients

  • 2 cups old fashioned rolled oats
  • 1 teaspoon baking powder
  • ½ teaspoon sea salt
  • 2 Tablespoons poppy seeds
  • 1 Tablespoon ground flaxseed

Wet Ingredients

  • 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 melted coconut oil
  • 1 teaspoon vanilla extract

Fruit

  • 1 ½ cups frozen or fresh blueberries (1 cup for mix-in and ½ cup for topping)

Other

  • Cooking spray for greasing
  • Toppings: extra blueberries, fresh lemon zest, yogurt, and/or maple syrup

Instructions

  1. Preheat and prepare the baking dish: Preheat your oven to 375° F (190° C). Spray an 8×8 inch square baking dish lightly with cooking spray to prevent sticking.
  2. Mix dry ingredients: In a large mixing bowl, combine the rolled oats, poppy seeds, baking powder, and sea salt. Stir these together to evenly distribute the ingredients.
  3. Add wet ingredients and blueberries: Pour in the plant-based milk, Greek or vegan yogurt, lemon juice, lemon zest, maple syrup, ground flaxseed, melted coconut oil, and vanilla extract. Add 1 cup of blueberries into the mixture. Stir everything well until all ingredients are fully incorporated.
  4. Transfer to baking dish: Carefully pour the oatmeal mixture into the prepared baking dish, spreading it evenly. Sprinkle the remaining ½ cup of blueberries over the top to create a fresh, vibrant topping.
  5. Bake: Place the baking dish in the preheated oven and bake for 40 to 50 minutes, or until the top is nicely golden and the oatmeal has set.
  6. Cool and serve: Remove from the oven and allow the baked oatmeal to cool for a few minutes. Slice into portions and serve warm. Add extra blueberries, fresh lemon zest, yogurt, and/or a drizzle of maple syrup on top for added flavor.

Notes

  • This recipe can be made with either fresh or frozen blueberries; no need to thaw frozen berries before adding.
  • For a vegan version, use plant-based yogurt instead of Greek yogurt.
  • Ground flaxseed helps to bind the oatmeal and adds extra nutrition. You can substitute with chia seeds if preferred.
  • Make sure to spray your baking dish well to prevent sticking or line it with parchment paper for easy removal.
  • Leftovers can be stored covered in the refrigerator for up to 4 days and reheated gently in the microwave.
