Blueberry baked oatmeal is my go-to brunch recipe when I need something delicious, nourishing, and crowdโ€‘friendly.

Let’s discuss the simple ingredients!

Ingredients For The Baked Oatmeal With Blueberries

Blueberries (fresh or frozen): They add bursts of juicy, tart sweetness and a boost of antioxidants. No blueberries? You can use raspberries, strawberries, or even diced apples instead.

Rolled oats or quick oats: Chewy, filling, and naturally gluten-free (just make sure the label confirms it). You can swap in regular old fashioned oats if gluten isn’t a concern. I use gluten-free sprouted oats.

Large Eggs: Essential for binding everything into a sliceable, cake-like bake. For an egg-free version, you could try flax eggs or your favorite egg replacer, though the texture may be a little softer.

Coconut or almond milk: Adds creaminess without any dairy. Either one works great, or feel free to use any non-dairy milk like oat milk, soy milk, cashew milk, or regular milk if youโ€™re not avoiding dairy.

Pure maple syrup: A natural sweetener thatโ€™s rich and mellow. Honey or brown sugar works too, or try date syrup or agave if you have it on hand.

Vanilla extract: A little splash goes a long way to round out the sweetness and deepen the flavor. No vanilla? Try almond extract for a twist (just use less, itโ€™s stronger!).

Baking powder, cinnamon, sea salt: Light lift from baking powder, cozy spice from cinnamon, and salt to enhance all the flavors. You can skip the cinnamon if youโ€™re not into spice.

Coconut flakes (optional): These add subtle sweetness, texture, and a bit of coconut flavor. Not a fan? Just leave them out, or try slivered almonds or chopped walnuts for a little crunch.

Now that we’ve covered the wholesome ingredients, let’s make this delicious blueberry oatmeal bake!

How to Make Blueberry Baked Oatmeal

Start by preheating your oven to 350ยฐF and lightly greasing an 8×8-inch square baking dish.

In a large mixing bowl, combine your dry ingredients: rolled oats, flaked coconut (if using), baking powder, cinnamon, and a pinch of sea salt. Give it a quick stir to evenly distribute everything.

Dry ingredients on top of wet ingredients in a large bowl to make cookies.

In a separate bowl, whisk together the eggs, coconut milk, maple syrup, and vanilla. 

Wet ingredients for banana oatmeal muffins in a mixing bowl.

Now pour the wet ingredients into the bowl of dry ingredients and stir until everything is well combined. Next, stir in the blueberries!

Transfer the mixture to your baking dish, smoothing the top. Bake for 55 to 65 minutes, or until the center is set and golden brown around the edges.

Oats, cinnamon and salt on top of the wet ingredients.

Let the oatmeal cool for 20 to 30 minutes before slicing – this helps it firm up so it doesnโ€™t fall apart. Then serve it warm, or store it in the fridge for easy grab-and-go breakfasts throughout the week.

Slice it into individual portions and use this easy breakfast as meal prep the next time you’re getting organized for the week.

Frequently Asked Questions

Can I use steel-cut oats instead of rolled oats?

Steel-cut oats wonโ€™t work well in this recipe without major adjustments. They take much longer to cook and need more liquid. Stick with old-fashioned rolled oats for the best texture.

Can I prep this the night before and bake in the morning?

You can! Mix everything up and store it in the fridge overnight, then bake it in the morning. Let the dish sit at room temperature while the oven preheats to prevent cracking.

How should I store leftovers?

Refrigerate in an airtight container for up to 5 days. Reheat slices in the microwave or oven until warm.

Can I freeze baked oatmeal?

Yes! Slice into portions, wrap individually, and freeze. Reheat in the microwave or oven straight from frozen for a quick breakfast.

Recipe Adaptations & Additions

  • Nutty boost – Stir in a handful of chopped walnuts or pecans for a satisfying crunch and extra healthy fats. They toast up beautifully in the oven and add great texture. Chia seeds of flax seeds are great additions too.
  • Chocolate twist – Fold in dark chocolate chips or cacao nibs before baking for a richer, slightly indulgent take thatโ€™s still wholesome enough for breakfast.
  • Zesty pop – Add lemon zest or orange zest to the batter for a bright citrusy note that complements the blueberries beautifully.
  • Spice it up – Want a warmer flavor? Mix in nutmeg, cardamom, or a little extra cinnamon into the dry ingredients.
  • Crunchy topping – Sprinkle the top with sliced almonds, sunflower seeds, or a little coconut sugar before baking for a sweet, crispy finish.
  • Berry swap โ€“ Use raspberries, blackberries, or a berry medley instead of blueberries. Keep the ratio about the same.
  • Individual servings – Bake the mixture in muffin tins for portable single-serve oatmeal cups. Great for busy mornings or packed lunches.

What to Serve With This Blueberry Oatmeal 

You can serve baked oatmeal warm with fresh fruit and a dollop of plain yogurt or coconut whipped cream to enhance the natural sweetness and add a creamy finish. For a brunch table, round things out with a mix of light, refreshing, and colorful pairings like:

Questions and Reviews

    1. Hi Nancy! You’d need to make some other changes to the recipe in order for it to work with steel cut oats. Specifically, the bake time will need to be longer although I’m not sure by how much as I haven’t tested it myself. If it were me, I’d google a baked oatmeal recipe that uses steel cut oats to be sure it turns out as expected. Let me know if you have any other questions!

  1. Ok, Iโ€™ve been looking at this recipe way too many times now! I am finally baking it today, so excited to get it out of the oven. Looks good and nutritious so I hope it will last for this weekend๐Ÿ˜‹๐Ÿ™ My boyfriend taught Iโ€™m making oat blueberry bars, so weโ€™ll see what comes out. Itโ€™s a long wait for me, which is why I am prep-ing it in advance for tomorrowโ€™s brunch๐Ÿคž๐Ÿ˜‹ thank you!

  2. AMAZING recipe. The lack of ingredients made me feel skeptical when I was in the process of making it, but wowowow it tastes like regular raisin milk bread I buy in stores. Thank you, Julia!

  3. It’s been a few months since I’ve become dairy-free so this delicious recipe is going to help me! ๐Ÿ™‚

    1. Hi Barbara,

      You can make it without egg for sure! I would try using flax eggs or chia eggs because they will help a bit better with binding than applesauce, but applesauce (or banana!) may work too! Let me know what you end up doing! xo

  4. I made this today and it’s great! My young boys and hubby loved it. I used steels cut oats and they softened just fine. I followed the recipe, and baked at 360 degrees for 60 minutes. I’ll definitely make this again. Thanks!

  5. do you think I could use steel cut oats? (bob’s red mill gf) that’s all I have left. made before it’s great! I have to sub almond milk this time for someone’s coconut allergy. TY!!

  6. I tried this recipe and am now making it for a second time– it’s *that* good! The only substitute I made was that I used unsweetened vanilla almond milk instead of coconut. It still had this delightful creaminess and just the right amount of sweetness.

    This was such a winner! ๐Ÿ™‚ Thank you for sharing it!

  7. I made this for a ladies brunch yesterday and it was a big hit! I used whole organic milk (because I had it) and dotted the top with a couple of Tbls of Kerrygold butter before baking. Everyone wrote down the recipe and your blog name. Thanks for another one that knocks our socks off. Bravo!

    1. I forgot to add that I plan to try this in individual ramekins. The extras can be frozen – if there are any extras….

    2. Sarah, I’m so thrilled to hear you and your brunch mates enjoyed the baked oatmeal! It’s seriously one of my favorite baked oatmeal recipes I’ve made to date! Many thanks for sharing my site with your friends! xo

  8. This is the perfect breakfast for Sunday or just any morning! Love my oatmeal loaded with cinnamon and blueberries! Pinned!

  9. I think I wouldn’t even be able to portion control this. JUST GIVE ME THE WHOLE TRAY AND NO ONE WILL GET HURT.
