Prep time: 10 minutes
Cook time: 35 minutes
Total time: 45 minutes
Servings: 6 generous portions

Ingredients

  • 2 cups (180 g) old-fashioned rolled oats (gluten-free certified if needed)
  • 1/3 cup (35 g) sliced almonds, divided
  • 1 teaspoon ground cinnamon
  • 1 teaspoon baking powder
  • 1/4 teaspoon fine sea salt
  • 1/4 teaspoon ground nutmeg (optional)
  • 2 cups (480 ml) unsweetened almond milk (or milk of choice)
  • 2 large eggs, lightly beaten
  • 1/3 cup (80 ml) pure maple syrup or honey
  • 2 tablespoons (30 ml) melted coconut oil or unsalted butter, cooled slightly
  • 1 1/2 teaspoons pure vanilla extract
  • 1 1/2 cups (225 g) fresh or frozen blueberries (do not thaw if using frozen)

Instructions

  1. Preheat your oven to 375°F (190°C). Lightly grease an 8-inch or 9-inch square baking dish with coconut oil, butter, or cooking spray.
  2. In a large mixing bowl, combine the rolled oats, half of the sliced almonds, ground cinnamon, baking powder, sea salt, and ground nutmeg. Stir thoroughly to distribute the spices and leavening evenly.
  3. In a separate medium bowl, whisk together the milk, beaten eggs, maple syrup, melted coconut oil, and vanilla extract until completely blended.
  4. Scatter half of the blueberries evenly across the bottom of the prepared baking dish.
  5. Pour the dry oat mixture over the blueberries in an even layer.
  6. Slowly pour the wet mixture over the oats, ensuring all the dry spots are gently moistened. Lightly tap the baking dish on the counter so the liquid settles completely through the oats.
  7. Scatter the remaining blueberries and the remaining sliced almonds evenly over the top surface.
  8. Bake uncovered for 35 to 40 minutes, or until the top is golden brown and the center feels set when gently pressed.
  9. Remove from the oven and allow the oatmeal to rest in the dish for 10 minutes before slicing. Serve warm or at room temperature.

Tips for consistent results

  • Use old-fashioned rolled oats: Rolled oats provide the best chewy, tender crumb. Quick-cooking oats can turn gummy, while steel-cut oats will not soften adequately within this baking time.
  • Keep frozen berries frozen: If you are using frozen blueberries, fold them directly into the dish straight from the freezer. Thawing them beforehand releases excess moisture, which can tint the batter gray and make the texture overly soggy.
  • Let it rest before slicing: Giving the bake 10 minutes to cool allows the residual steam to settle and makes it easy to cut neat, clean squares that hold their shape.
  • Adjust sweetness to taste: If your blueberries are very sweet or you prefer to top your slice with a drizzle of maple syrup at the table, you can reduce the syrup in the batter to 1/4 cup without altering the texture.

Variations

  • Nut-Free Alternative: Substitute the sliced almonds with raw pumpkin seeds (pepitas) or sunflower seeds for a school-safe, allergy-friendly crunch.
  • Berry Medley: Swap half of the blueberries for chopped fresh strawberries, raspberries, or blackberries to add a pleasant tart contrast.
  • Warm Apple Walnut: Replace the blueberries with finely diced tart apples and substitute the sliced almonds with roughly chopped raw walnuts.
  • Dairy or Non-Dairy Flexibility: Any unsweetened milk works seamlessly here, including oat milk, soy milk, cashew milk, or traditional cow’s milk.

Storage and Meal Prep

  • Refrigeration: Allow the baked oatmeal to cool completely to room temperature. Slice into individual portions and store in an airtight container in the refrigerator for up to 5 days.
  • Freezing: Wrap individual cooled squares tightly in parchment paper and place them in a freezer-safe bag or container. Freeze for up to 3 months.
  • Reheating: Warm chilled portions in the microwave for 45 to 60 seconds, or heat in a 350°F (175°C) toaster oven for 8 to 10 minutes until heated through. Frozen squares can be thawed overnight in the fridge or warmed directly using the defrost setting on your microwave.

Frequently Asked Questions

Can I make this baked oatmeal vegan?

Yes. You can replace the two chicken eggs with two flax eggs (mix 2 tablespoons of ground flaxseed with 5 tablespoons of water and let sit for 5 minutes until gelled). The texture will be slightly softer but holds together well.

Can I assemble this the night before?

You can mix the dry ingredients and wet ingredients in separate bowls the night before. In the morning, combine them in the baking dish with the blueberries and bake as directed. Soaking the oats overnight in the liquid before baking can lead to a denser, more pudding-like texture, which some enjoy, but baking fresh produces the best crumb.

How should I serve baked oatmeal?

It is delicious served warm on its own, but you can also serve it in a shallow bowl with a splash of warm almond milk, a dollop of plain Greek yogurt for extra protein, or a light drizzle of almond butter or maple syrup.
