👩‍🍳 How to Make Blueberry Baked Oatmeal (Step-by-Step)

This baked oatmeal comes together in under 30 minutes—no fancy tools or skills required.

1. Preheat & Prep

• Preheat your oven to 350°F (180°C).
• Line an 8×8-inch baking dish with parchment paper or lightly grease it.

2. Mix the Base

• In a large mixing bowl, mash your bananas.
• Stir in the oats, almond butter, and sweetener if using.
• Fold in half the blueberries gently with a rubber spatula.
• If the batter looks too thick, add a splash of milk. Too runny? Add an extra sprinkle of oats.

3. Bake It

• Pour the batter into your prepared baking dish.
• Sprinkle the top with the remaining blueberries and optional mix-ins like walnuts.
• Bake for 15–20 minutes, or until the edges are golden and the center is just set.

4. Cool and Slice

• Let the baked oatmeal cool in the pan for 15 minutes.
• Carefully transfer it to a wire rack or cutting board to cool fully.

🧠 Tips for Perfect Protein Baked Oats

I’ve made this recipe dozens of times (it’s my Sunday meal prep staple), and here’s what I’ve learned:

• Use super ripe bananas – the riper, the sweeter.
• For extra protein, mix in a scoop of your favorite vanilla or unflavored protein powder.
• Want it sweeter without sugar? Add a few chopped Medjool dates to the mix.
• Try apple chunks, raspberries, or even grated carrots to mix it up.
• Store leftovers in an airtight container in the fridge for up to 5 days or freeze slices individually for grab-and-go mornings.

❓ Blueberry Baked Oatmeal FAQs

What makes baked oats high in protein?

The almond butter adds healthy fats and protein. You can also boost it with chia seeds or a scoop of protein powder.

Why are my baked oats gummy?

This usually happens if they’re underbaked or if too much liquid is added. Use a toothpick to check doneness!

Can I make this without banana?

Yes! Try unsweetened applesauce or Greek yogurt as a substitute.

Can I use steel-cut oats?

Nope, they don’t work well here. Stick with rolled oats for the right texture.

Is baked oatmeal good cold?

Absolutely! My kids actually prefer theirs chilled from the fridge with a drizzle of almond milk.

🥄 What to Serve with Baked Oatmeal

• A dollop of Greek yogurt
• A drizzle of nut butter
• Fresh berries or sliced banana
• Hot coffee or iced matcha on the side
