Full ingredient measurements are in the recipe card below!

Directions

Step 1: Preheat and Prepare the Baking Dish

Preheat your oven to 375°F (190°C). Grease a baking dish (8×8 or similar size works well) with butter or non-stick spray.

Step 2: Mix the Wet Ingredients

In a bowl, whisk together eggs, milk, maple syrup (or honey), vanilla extract, and a pinch of salt. Make sure everything is well combined.

Step 3: Combine the Dry Ingredients

In another bowl, mix the oats, baking powder, and cinnamon. Stir the dry ingredients into the wet mixture until everything is well combined.

Step 4: Add the Blueberries

Gently fold in the blueberries, whether they’re fresh or frozen. Be careful not to crush them too much.

Step 5: Bake the Oatmeal

Pour the oatmeal mixture into the prepared baking dish. Spread it out evenly and bake for 35-40 minutes, or until the top is golden and the oatmeal is set. You can test doneness by inserting a toothpick—it should come out clean when the oatmeal is cooked through.

Step 6: Let it Cool and Serve

Let the baked oatmeal cool for a few minutes before serving. Slice into squares and enjoy! Top with extra blueberries, a dollop of yogurt, or a drizzle of maple syrup for extra indulgence.

Expert Tips and Tricks

For Creamier Oatmeal: Use full-fat milk or a rich non-dairy milk like coconut or oat milk.
For Extra Crunch: Sprinkle chopped nuts (like walnuts or almonds) on top before baking.
Don’t Overmix: When folding in the blueberries, mix gently to keep them intact and preserve their burst of flavor.

Recipe Variations and Possible Substitutions

Different Fruits: Swap blueberries for other berries like strawberries, raspberries, or blackberries. You can also use diced apples or peaches.
Spices: Add a pinch of nutmeg or cardamom for a warm, spiced flavor.
Add-ins: Stir in chia seeds, flaxseeds, or coconut flakes for added texture and nutrition.

Serving and Pairing Suggestions

This baked oatmeal is delicious on its own, but you can serve it with a side of Greek yogurt, a handful of granola, or a splash of almond milk for extra creaminess. It pairs beautifully with a cup of coffee or freshly brewed tea.

Storage and Reheating Tips

Storage: Store leftover oatmeal in an airtight container in the fridge for up to 4 days.
Reheating: To reheat, microwave individual servings for 30-60 seconds or warm it up in the oven at 350°F for 10 minutes.
Freezing: Baked oatmeal can be frozen! Slice it into portions and wrap them tightly before freezing. Reheat directly from the freezer in the microwave or oven.

FAQs

1. Can I use steel-cut oats instead of rolled oats?
Steel-cut oats take longer to cook and may not work as well in this recipe, so it’s best to stick with rolled oats for the ideal texture.

2. Can I make this ahead of time?
Yes! You can assemble the oatmeal the night before, cover it, and refrigerate it overnight. In the morning, just pop it in the oven to bake.

3. Can I use frozen blueberries?
Absolutely! Frozen blueberries work just as well as fresh ones. Just add them directly to the mixture without thawing.

4. Can I add protein to this oatmeal?
For a protein boost, stir in a scoop of protein powder, Greek yogurt, or even some nut butter before baking.

Blueberry Baked Oatmeal is a comforting, nutritious, and easy-to-make breakfast that’s perfect for busy mornings or a leisurely weekend treat. With its soft, custard-like texture and burst of juicy blueberries, it’s sure to satisfy your cravings and fuel you for the day ahead.
