Blueberry Baked Oatmeal is my go-to breakfast for busy weekdays or cozy weekends—a healthy, one-dish morning treat that bakes into a golden, berry-studded delight.
Here’s the thing: this breakfast bake feels both nostalgic and fresh, landing somewhere between grandma’s kitchen and your modern meal-prep dreams. Packed with fiber-rich oats, antioxidant–loaded berries, and a touch of honey, it’s perfect for families, office potlucks, or that Sunday morning when you crave something warm and filling. Honestly, I started tinkering with this recipe in my 20s when my grocery budget was tighter than tight; now, as a fifty-year-old foodie, I still can’t resist that burst of sweet-tart blueberry in every forkful. Plus, each serving offers about 5 g of fiber—nearly 20% of your daily goal, according to USDA data.

Ingredients
- 2 cups rolled oats (old-fashioned; pick certified gluten-free if you need it)
- 1½ cups fresh or frozen blueberries (rinse fresh; if frozen, avoid over-thawing)
- 2 cups milk (whole, skim, or almond/oat milk)
- 2 large eggs (room temperature for even blending)
- ½ cup plain Greek yogurt (whole-milk style for extra creaminess)
- ¼ cup maple syrup or honey (local, raw honey adds floral notes)
- 1 teaspoon pure vanilla extract (for cozy aroma)
- 1 teaspoon baking powder (ensures a gentle rise)
- ½ teaspoon ground cinnamon (optional for warmth)
- Pinch of salt (to balance flavors)
- 2 tablespoons melted butter or coconut oil (for richness)
- Optional toppings: sliced almonds, extra berries, a drizzle of honey (for crunch and flair)
Directions
- Preheat the oven to 350°F (175°C) and grease a 9×9-inch baking dish with butter or nonstick spray—lining it with parchment makes cleanup a breeze.
- In a large bowl, whisk eggs, milk, Greek yogurt, maple syrup, vanilla, melted butter, cinnamon, and salt until smooth and frothy; taste and add a bit more sweetener if you crave it.
- Stir in oats and baking powder until every flake is moistened, then let the mixture rest for 5 minutes so the oats soften—trust me, it’s worth the wait.
- Gently fold in blueberries, saving a handful to scatter on top; frozen berries are fun but can tint the batter purple, so handle with care.
- Pour the batter into your prepared dish, use a spatula to level it, and sprinkle reserved berries or nuts for visual appeal.
- Bake for 35–40 minutes, until the edges are set and the center jiggles just slightly—a toothpick should come out with a few moist crumbs.
- Let the bake cool for 10 minutes on a wire rack; resting time firms up the center and makes slicing cleaner.
- Slice into 6–8 squares and serve warm, at room temperature, or chilled—add a splash of milk, yogurt, or even a scoop of vanilla ice cream for a decadent twist.

Storage & Reheating
- Store leftovers in an airtight container in the fridge for up to 4 days.

Notes
- Resting the oat mixture before baking cuts grittiness—5 minutes turns it silky.
- For a cakier texture, drop milk by 2 tablespoons; for a looser feel, add 2 more.
- Swapping one egg for an extra tablespoon of yogurt yields a moister crumb.
- Each serving delivers about 250 calories, 8 g protein, and 5 g fiber—tracked with USDA data.
FAQs
Q: Can I use steel-cut oats?
A: Yes, but they’ll need more liquid and 10–15 extra minutes in the oven—texture gets chewier.
Q: What if I don’t have Greek yogurt?
A: Swap sour cream or extra milk; texture shifts slightly but stays rich.
Q: How do I prevent sogginess?
A: Don’t skip the resting step, and respect bake time—cooling firms it up.
Q: Can I add protein powder?
A: Absolutely—stir in 1 scoop of vanilla or unflavored powder, then thin with a splash more milk.
Q: Are frozen berries okay?
A: For sure—use them frozen to minimize color bleed and keep bounty all year.

A: It is if you choose certified gluten-free oats—friendly for sensitive tummies.
