Assemble and Bake:
- Layer Blueberries: Spread half of the blueberries evenly over the bottom of the prepared baking dish.
- Add Oats: Pour the dry oat mixture over the blueberries and spread it out evenly.
- Add Wet Mixture: Pour the wet mixture evenly over the oats, ensuring all oats are covered. Gently shake the dish to distribute the liquid.

Bake:
- Bake the Oatmeal: Place the dish in the preheated oven and bake for 30–35 minutes, or until the top is golden and the oatmeal is set.

How to Serve

- With Milk: Drizzle a splash of milk or cream over the top for added richness.
- With Yogurt: Pair with a dollop of Greek yogurt for extra protein.
- Sweet and Crunchy: Top with a drizzle of honey or a sprinkle of granola.

Additional Tips

- Try Other Fruits: Substitute the blueberries with raspberries, chopped apples, or diced peaches.
- Make It Vegan: Use a flaxseed egg (1 tablespoon flaxseed meal + 3 tablespoons water) and non-dairy milk.
- Storage Tips: Store leftovers in the refrigerator for up to 5 days.
Recipe Variations
- Berry Medley: Combine blueberries, raspberries, blackberries, and even strawberries for a vibrant, multi-fruit oatmeal.
- Chocolate Delight: Fold in dark chocolate chips for a rich, indulgent twist that adds sweetness and flavor to the oats.
- Banana Blueberry: Add slices of ripe banana to the blueberries for extra sweetness and a creamy texture that complements the fruit.
- Nut-Free Option: If you want to avoid nuts, substitute with chia seeds, sunflower seeds, or even hemp seeds for a boost of healthy fats and protein without the crunch of nuts.
- Spiced Oatmeal: Enhance the flavor of your oatmeal with warming spices like nutmeg, cardamom, or cloves for a fragrant, cozy breakfast.
- Apple-Cinnamon: Replace the blueberries with diced apples and boost the cinnamon flavor for a comforting, autumn-inspired variation.
- Coconut Cream Oatmeal: Use coconut milk as the base liquid for extra richness and finish with a sprinkle of toasted coconut for a tropical touch.

- Peanut Butter & Jelly: Stir in a spoonful of peanut butter for creaminess and top with a swirl of your favorite jam or preserves for a PB&J-inspired twist.
- Almond Joy Oatmeal: Add slivers of almonds, a drizzle of chocolate syrup, and a sprinkle of shredded coconut to capture the flavor profile of an Almond Joy bar.
- Chai Spice: For a spicy kick, mix in some chai spice blend (or cinnamon, ginger, cloves, cardamom, and black pepper) for a warm, aromatic oatmeal.
- Maple Pecan: Add chopped pecans and a drizzle of pure maple syrup for a sweet, nutty finish.
Freezing and Storage
- Freezing: After baking the oatmeal, allow it to cool completely. Slice the baked oatmeal into individual portions, wrap each piece tightly in plastic wrap, and place them in a freezer-safe container or bag. These portions can be stored in the freezer for up to 3 months. Freezing makes it easy to have a make-ahead breakfast on hand whenever you need it.
- Thawing: When ready to enjoy, remove the portion from the freezer and let it thaw in the refrigerator overnight for the best texture. If you’re in a rush, you can defrost in the microwave for 2–3 minutes on a low setting until soft.
- Reheating: To warm up your oatmeal, simply place individual servings in the microwave for 30 to 60 seconds, or heat in a preheated oven at 350°F (175°C) for about 10 minutes, until warmed through.
- Storage (Refrigerator): Store leftover baked oatmeal in an airtight container in the fridge for up to 5 days. Reheat in the microwave or oven as needed.
Special Equipment
- 9×9-Inch Baking Dish: This square dish provides the ideal surface area for baking the oatmeal evenly. It ensures that the oatmeal cooks uniformly and can be easily sliced into portions. If you don’t have a 9×9-inch dish, you can use a similar-sized baking dish as long as the proportions are similar.
- Mixing Bowls: Using separate bowls for your wet and dry ingredients allows for easier mixing and ensures your ingredients are properly incorporated. Choose bowls that are large enough to hold the combined ingredients without spilling, ideally one for dry ingredients and one for wet.
- Whisk and Spatula: A whisk is essential for mixing the dry ingredients and ensuring that the wet ingredients (like eggs, milk, and vanilla) are well-blended. After combining the ingredients, a spatula will help scrape down the sides of the bowl and ensure that all ingredients are mixed thoroughly, helping you get a smooth, consistent batter.

Yes, but the texture may be softer and less chewy. - Can I use steel-cut oats?
No, they require a longer cooking time and will not soften properly in this recipe. - How can I make this sugar-free?
Use an unsweetened sweetener substitute like stevia or monk fruit. - Can I add protein powder?
Yes, simply mix a scoop into the dry ingredients. - What’s the best way to reheat this?
Reheat portions in the microwave or oven until warmed through.
