What’s In This Healthy Blueberry Oatmeal Bake?

Keeping it simple is the name of the game with this blueberry baked oatmeal recipe! You’ll love how simple it is to whip up this tasty breakfast using items you likely already have in your pantry. Here’s what you’ll need:

Blueberries – We use fresh berries, but frozen blueberries can be substituted. Just adjust the baking time as needed to allow the extra liquid to absorb.
Rolled Oats – Old-fashioned oats can be used as well. Both have a thick, chewy texture that absorbs the liquid well. We do not recommend using speedy oats as they tend to become mushy and don’t bake as well. If needed, look for oats that are certified as being gluten-free.
Cinnamon – Used to add extra warmth and enhance the sweetness of the berries.
Baking Powder – This helps the oats rise as they bake. For the finest results, make sure it’s fresh.
Sea Salt – Use as little or as much as preferred.
Maple Syrup – Helps sweeten the mixture. Honey can be substituted if preferred.
Unsalted Butter – The fat helps enhance the flavors and keep you satiated. Coconut oil works well, too.
Milk – We use unsweetened almond milk, but any milk you have on hand will work great.
Large Eggs – These help provide structure to the oat bake, helping it hold its shape after it has been cooked.

Both work! Warm it up for cozy vibes (maybe with a splash of milk), or eat it cold straight from the fridge for a speedy breakfast or snack.

Can I add other fruits?

Definitely! Blueberries play well with bananas, apples, raspberries, or peaches. Toss in whatever’s in season or hanging out in your fridge.
