Baked Oatmeal Recipe
I love old-fashioned rolled oats! They are so versatile for anyone looking for a gluten-free breakfast. Rolled oats can be eaten as morning oatmeal, or used in a variety of recipes.
- DELICIOUS - I love the simple flavors of baked blueberries, cinnamon and applesauce!
- EASY - Just dump the easy ingredients into a large bowl, mix together and bake!
- HEALTHY - This recipe uses the goodness of oatmeal and turns it into an easy breakfast cake. Honey and applesauce are both natural sweeteners used in this recipe.
I love to serve my baked oats with plain greek yogurt. Especially when it's warm from the oven. It's sooo good and tastes like you're eating dessert for breakfast.
Recipe Ingredients
This baked oatmeal comes together easily. Everything can be prepped with a few simple ingredients. Here's an overview of what you'll need with full details in the recipe card at the bottom of this post:
- ROLLED OATS - Choose old-fashioned rolled oats for the perfect texture and consistency. This will give a hearty flavor. You can also use quick oats but avoid using flavored quick oats because this will change the recipe's taste. Steel-cut oats will not work.
- BLUEBERRIES - You can use fresh or frozen blueberries. Frozen blueberries tend to bleed so you can sprinkle them into the baking dish to prevent the batter from turning a purple color (see recipe card for details).
- APPLESAUCE - Applesauce will add moisture and will sweeten the oatmeal bake.
- HONEY - I used honey for this recipe. You can also use maple syrup.
- Milk - You can use regular milk, dairy-free milk (almond milk, hemp milk, coconut milk, etc) or even water if you are out of milk.
- CINNAMON - Cinnamon tastes delicious with any oat recipe. This recipe uses 1 tsp of cinnamon, you can use more or less depending on preference.
- VEGETABLE OIL - A bit of oil helps the oats to stay together and bake. You can swap for canola oil, coconut oil, avocado oil, melted butter or vegan butter.
- EGGS - You'll need two large eggs
- OTHER – You'll also need baking powder, salt and vanilla extract.
Helpful Tip: I used my favorite sprouted gluten-free rolled oats and just love 'em! This is my favorite brand to use in all of my gluten-free oats recipes and baking!
Variations
Feel free to add extra ingredients to the batter for more flavor and nutrition! Nuts, seeds, fruit, and spices can really change the flavor. Here are a few ideas:
- CHIA SEEDS - These can be added straight to the batter.
- FLAXSEED - Add ground flax seed for additional fiber.
- LEMON ZEST - Blueberries and lemon zest taste so lovely together. Add a bit of zest straight to the batter for a more citrus taste.
- MIXED BERRIES - Swap the blueberries with frozen mixed berries.
- NUTS AND SEEDS - Add ½ cup of chopped nuts or pumpkin seeds for added crunch and protein.
- SPICES - Change the flavor of spices by adding nutmeg, ground cloves, or pumpkin pie spice like I did in our pumpkin spiced baked oatmeal.
How To Make Blueberry Baked Oatmeal
This recipe is incredibly easy to make. Just dump ingredients into a bowl, mix together, pour and bake! Here's an overview with full instructions in the recipe card at the bottom of this post:
- DRY INGREDIENTS - Add rolled oats, cinnamon, baking powder and salt to a medium mixing bowl. Stir together then set aside.
- WET INGREDIENTS - Add the milk, applesauce, honey, eggs, vegetable oil, and vanilla extract to a large mixing bowl and stir together.
- COMBINE - Pour the dry ingredients into the wet ingredients and mix together until it forms a batter. Let this oatmeal mixture sit for 20-30 minutes so that the oats can absorb the liquid.
- ADD TO BAKING DISH – Add half of the batter to a greased baking dish. Sprinkle the top with half of the blueberries. Add the last half of the batter, followed by the last half of the blueberries. Sprinkle the top with cinnamon if desired. Bake for 40-45 minutes, or until golden brown and a toothpick come out clean.
Helpful Tip: Sprinkling the blueberries on top of the oat batter will avoid that greyish-purplish color that happens when you add frozen blueberries to the batter.
How To Store Baked Oatmeal
Easily store these baked oats for a later day when you want to enjoy them. They hold their moisture incredibly well and taste just as good as the day you made them.
- TO STORE – Store in an airtight container in the fridge or at room temperature for up to 3 days.
- FREEZE – An easy trick to prevent serving slices from sticking together is to flash-freeze them on a baking sheet lined with parchment paper for 2 hours. After that, place them in a large freezer bag and remove as much air as possible. These can be frozen for up to 3 months for the best freshness.
- REHEAT – To reheat, place in the microwave for 30 seconds wrapped in a paper towel.
What To Serve With
This blueberry baked oatmeal can be served for breakfast, brunch, afternoon snack, or dessert. It tastes incredible on its own, but here are some options for sides and toppings.
- CLASSIC TOPPINGS – Drizzle on maple syrup, or honey, or sprinkle powdered sugar
- BACON & EGGS – Served on the side with a classic breakfast of bacon and eggs.
- FRESH FRUIT – Top with more blueberries, strawberries, raspberries, or sliced bananas
- CHOPPED NUTS – Use as a garnish and as an added flavor. I like sliced almonds lightly toasted in a dry pan.

- ICE CREAM – For a special treat, add a scoop of vanilla ice cream.
Frequently Asked Questions
Yes! The flavor and texture of blueberries pair nicely with any style of oatmeal, including baked oats. Fresh blueberries will hold their shape a little better, while frozen blueberries have more moisture and can produce a mushier consistency. Both will taste great!
Make sure to bake your oats for 40 minutes. This will confirm that they are cooked underneath and aren’t mushy inside. Too much moisture can also produce mushy oats, so use the proper measurements of applesauce and milk to ensure that the oats have had enough time to soak up some of that moisture.
Yes, rolled oats are high in fiber and can be a great way to start your day. You can also add nutritious ingredients like blueberries, applesauce, greek yogurt, nuts and seeds that can also provide energy to start the day.
