Blueberry Baked Oatmeal Recipe

This easy & healthy Blueberry Baked Oatmeal recipe is a delicious make-ahead breakfast to feed a crowd! It's high-protein, gluten-free and refined sugar free, and very customizable!

This healthy Blueberry Baked Oatmeal recipe is the culmination of my quest to create a baked oatmeal recipe that is...

1. Healthy. Many baked oatmeal recipes use copious amounts of butter and sugar...which are not excellent sources of fuel for your body first thing in the morning.
2. Rich in protein. Oatmeal is great, but one cup only has 6 grams of protein. Eating more protein increases energy and helps you stay full longer. Win. Win.
3. Delicious. No need for an explanation here!

This Blueberry Oatmeal recipe truly the best! It is gluten-free and refined-sugar free.  The addition of almond meal and Greek yogurt make it high in protein.  The vanilla and cinnamon compliment the berries so well, and fill the house with a heavenly aroma as it bakes in the oven! Plus it's easily made ahead for busy mornings!

Blueberry Baked Oatmeal: Ingredients & Substitutions

Ok, now onto substitutions! This is a very versatile recipe so here are a few ways to tweak it if you wish, although I always recommend making the recipe exactly as it's written! 😉

• Old-fashioned oats: Quick-cooking oats can be used in place of old-fashioned, you will need to decrease your baking time by about 10 minutes though.
• Almond meal: I love the nutty flavor and boost of protein this adds, but if you need to omit almond meal simply add an extra ¼ cup oats or oat flour.
• Coconut Sugar: Any sweetener can be used here...granulated or liquid! I have used honey, coconut sugar, regular organic sugar and maple syrup, all with great results.
• Butter/Coconut oil: Either butter or coconut oil works beautifully in this recipe.
• Milk: Any dairy-full or dairy-free variety of milk works perfectly in this recipe. The richer the milk, the creamier and tastier the recipe will be.
• Greek Yogurt: Vanilla & Honey flavored Greek yogurt is my absolute favorite! If you use plain Greek yogurt might want to increase the sweetener by a tablespoon or two, or add a touch of honey.
• Blueberries: I know the title of this recipe is "Blueberry Baked Oatmeal" but you really can use any berry you like and it will taste amazing! I often use the frozen mixed berry medley from Costco! If you use fresh berries you will need to decrease your baking time, so watch it carefully.

How to make Blueberry Baked Oatmeal

This blueberry oatmeal is very easy to make, but we'll walk through the steps together to ensure your success! Don't forget to watch the video too!

Combine Dry Ingredients

Begin by combining the dry ingredients in a small bowl. By doing this first, you ensure that the dry ingredients are evenly distributed in the final product.

Whisk together wet ingredients

In a large bowl, whisk together eggs, Greek yogurt (or sour cream), and vanilla extract until the mixture is homogenous (uniform throughout). 

Whisk in Milk

Next, add the milk to the wet ingredients and whisk to combine. 

Combine Wet & Dry Ingredients

Add the dry ingredient mixture to the wet ingredients and use a spatula to stir to combine. 

Add Blueberries

Gently fold in the blueberries. If you smash them too much the baked oatmeal will become purple/gray in color! 

Note: Lots of Liquid

One thing to note about this berry baked oatmeal recipe is that it is very liquidy when you pour it into the pan to bake. Do not let that worry you, the oats will absorb the liquid as it bakes.

Bake & Cool

Bake the blueberry baked oatmeal until the edges are golden brown and the top is set. Let cool for at least 10 minutes, and serve warm! Note: Bake time varies depending on the type of oats you use. Be sure to watch it carefully.

To make ahead

Bake the night before & reheat.  I usually make this Blueberry Baked Oatmeal the night before, store it in the fridge, then just warm in the oven the next morning. It takes 5 minutes to throw together and 35 minutes to bake, plus it uses ingredients I almost always have on hand!
Make batter ahead of time and bake in the morning. You can also make the batter the night before - just leave out the blueberries-  and store it in an airtight container in the refrigerator. In the morning, fold in the blueberries, spread it into a baking dish and bake! 

Serve

I love serving this blueberry baked oatmeal with a glug of pure maple syrup! You can also add a dollop of homemade whipped cream, homemade peanut butter (for a PB&J vibe), homemade almond butter, or another favorite - slather it with this homemade cinnamon honey butter!

Store/freeze

Store any leftovers in an airtight container in the refrigerator for up to 5 days, or in the freezer for up to 2 months! To reheat, simply warm in the microwave or the oven (set to 300 degrees) until warmed through.
