Ideal for those who enjoy sweet breakfasts, but also like to keep it on the mindful end of the spectrum, this easy blueberry breakfast bake is here to bring both sweetness and balance. It is made with all whole food ingredients and zero excess flour!

It includes healthy fats, a decent dose of protein, and complex carbohydrates for an energizing way to start the day. Protein fiends like me, enjoy it alongside some Greek yogurt or cottage cheese for the ultimate filling breakfast.

Plus, it tastes great! Ripe bananas and fresh blueberries do most of the speaking, and a nutty oat undertone makes the whole thing swoon-worthy.

Make it as a meal prep recipe for grab-and-go breakfasts for busy mornings, or enjoy it over the weekend!

Ingredients for Blueberry Breakfast Bake

Rolled Oats: The base of the recipe is whole grain rolled oats. You can also use quick oats (or instant oats) if you prefer. For gluten-free breakfast bake, be sure to use certified gluten-free oats. I use gluten-free sprouted oats.

Ripe Bananas: Overripe bananas make up the majority of the sweetness and moisture. Be sure to pick bananas that have plenty of brown spots, as this signifies they are very sweet and moist, which generates the best results.

Fresh Blueberries: The main star here, blueberries bring little pops of sweet and tangy berry flavor. I recommend sticking with fresh blueberries, but you can use frozen blueberries too. Just note that frozen berries let out more liquid than fresh berries so the texture will be moister.

Almond Butter (or Nut Butter of Choice): Pick your favorite nut butter! It is here to bring richness and to add healthy fats and some protein to the recipe to balance it all out.

I use almond butter or cashew butter because their flavors get overshadowed by the banana and blueberries. Peanut butter also works too.

Large Eggs: A couple of eggs help our breakfast bake rise to a fluffy yet dense texture. You can replace them with two flax eggs for an egg-free version.

Milk or Cottage Cheese: Because oats absorb liquid, some form of milk or other liquid is needed to get the ratio of wet to dry right. I like using cottage cheese or Greek yogurt for extra protein, but any kind of milk works too.

Whole milk, almond milk, oat milk, coconut milk, and cashew milk are all fabulous options.

Pure Maple Syrup (optional): A touch of pure maple syrup levels up the sweetness to just the right amount. You can adjust the sweetener to your personal taste.

Ground Cinnamon: A generous amount of ground cinnamon adds warm flavor to our breakfast party.

Pure Vanilla Extract: A splash of vanilla essence adds a lovely warm nuance.

Sea Salt: Salt is a major flavor enhancer, so don’t leave it out or you’ll be leaving flavor on the table.

Ways to Customize

No Added Sugar: Omit the pure maple syrup for a no added sugar option that is only fruit-sweetened.
Nutty Crunch: Mix ⅔ cup of chopped pecans or walnuts into the oatmeal mixture if you love a little crunch.
Chocolate Infusion: Add in ½ cup to ⅔ cup of chocolate chips for little pockets of chocolate goo.
Swap the Fruit: Use fresh strawberries, raspberries, cherries, blackberries, peaches, or apples instead of blueberries. You can also add lemon zest for a citrus infusion.
Turn it Into Muffins: Make my Blueberry Banana Baked Oatmeal Cups to turn the recipe into individual servings.

How to Make Blueberry Breakfast Bake

Preheat the oven to 350 degrees Fahrenheit, and line a 9” x 9” baking pan with parchment paper.

Mash the ripe bananas in a large bowl until most of the chunks are out.

Add in the almond butter (or nut butter of choice), eggs, milk, pure maple syrup, and pure vanilla extract and mix well until everything is combined.

Bake on the center rack of the preheated oven for 25-28 minutes or until the breakfast bake has set up and is slightly golden brown on top.

Allow the breakfast bake to cool for at least 15 minutes before slicing and serving. The longer you allow the casserole to cool, the cleaner the slices will be.

Serve with your choice of protein, such as Greek yogurt or cottage cheese and fresh fruit!

Storage Options

Room Temperature: Cover the baking dish with plastic wrap and store on the counter for up to 2 days.
Refrigerator: Transfer leftovers to an airtight container and refrigerate for up to 5 days.
Freezer: Freeze in a freezer bag or a freezer-safe container for up to 2 months.

Recipe Tips

Be sure your nut butter is at room temperature or warmer so that it mixes in with the wet ingredients easier. If it has been sitting in the refrigerator, microwave it for 30 seconds, or until it stirs easily.
If you find the breakfast bake isn’t sweet enough for you, you can add a drizzle of maple syrup or honey, or sprinkle it with brown sugar.
Make Ahead Instructions: prepare the recipe the night before and bake it off the next morning.
