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.
• Almond meal: you can replace the almond meal with an extra ¼ cup oatmeal.
• Granulated Sugar: coconut sugar, light brown sugar, honey or maple syrup are all good substitutes for granulated sugar. 
• Salted butter. coconut oil or unsalted butter are good substitutes. 
• Milk: choose your favorite milk, whole milk, 2%, coconut milk, almond milk, etc. 
• Greek yogurt: Choose your favorite yogurt, if using plain, increase the sweetener by at least 2 Tablespoons.
• Blueberries:  choose your favorite berries, they all taste amazing. 

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!

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.

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

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

Next, add the dry ingredient mixture to the wet ingredients and use a spatula to stir to combine. 

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

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 Prepare in Advance

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.
