Ingredient Notes
- Oats: Rolled oats are generally best to use for baked oatmeal. They have the perfect soft and chewy texture. In a pinch, you can use quick oats but it’s best to avoid steel cut oats as their texture is too tough and chewy. Use gluten-free certified oats if you have an intolerance.
- Baking powder: A little baking powder helps to lighten the oats so that they’re not so dense in texture.
- Milk: You can use dairy or any plant-based milk alternative.
- Unsweetened apple sauce and maple syrup: To sweeten the baked oats without the use of refined sugar. You can also sub in honey if desired.
- Eggs: To bind the ingredients together. You can also try using a chia or flax egg if you want to make this recipe vegan.
- Almond butter: Provides additional moisture to the baked oatmeal, along with some healthy fats and protein. You can sub in another nut or seed butter if preferred.
- Blueberries: I love the addition of blueberries in this oatmeal. They provide a subtle burst of flavour and natural sweetness that we can’t get enough of! I typically use fresh but you can also use frozen.
Step by Step Instructions for this Blueberry Oatmeal Bake
This recipe takes literally no time at all to prepare which is one of the reasons why I love it so much.
- First, you’ll need to preheat the oven to 350 degrees F. Grease a 7×11 inch rectangular baking dish.
- Next, mix all of the dry ingredients in a large bowl.
- Add the wet ingredients to the bowl and stir to combine.
- Add the blueberries and fold into the mixture.
- Pour the oatmeal mixture into the greased baking dish.
- Bake for 35-40 minutes or until inserted toothpick comes out clean.
- Allow to cool for several minutes before serving.
- Top with desired toppings.
Recipe Tips for the best Baked Oats
- Allow the baked oatmeal to cool for at least 15-20 minute before cutting it and removing it from the pan to give it a chance to firm up.
- If using frozen blueberries, add them from a frozen state (not a thawed state) to prevent them from releasing too much moisture into the baked oatmeal.
- If you wish to make this recipe with no added sugar, don’t add the quarter cup of maple syrup, and instead add one cup total unsweetened applesauce. This is especially recommended if serving to babies under the age of one.
- If serving to babies or toddlers, I recommend not adding the sliced almonds on top of the baked oatmeal as they may be a choking hazard.
Recipe FAQs
How to store
You can store this baked oatmeal in the fridge for up to a week in the baking pan covered with saran wrap or store the individual pieces in an air-tight container. Let it cool fully before storing to keep it nice and fresh.
Can I freeze baked oatmeal?
These baked oats are freezer-friendly and will keep well for up to 3 months. Cover it with foil or plastic wrap before placing it into a freezer safe container or bag to prevent freezer burn.
Defrost overnight in the fridge to enjoy the next morning, or warm it up in the microwave from frozen.
How to reheat
You can enjoy this baked oatmeal cold, but I much prefer to serve it warm.
To reheat, use one of the following methods:
Oven: You can reheat it in the oven at 350 degrees F, covering the top with foil, for around 20 minutes or until warmed through.
Microwave: You can warm individual squares in the microwave on full power for one minute. Perfect for a busy morning!
Should I use fresh or frozen blueberries?
It’s totally up to you! Both fresh or frozen blueberries work for this recipe.
I often find that frozen are more convenient since we always have some on hand, but both work great. If you are using frozen, don’t thaw them as their juices and colour can leak into the other ingredients, and release too much moisture. Instead, add them to the mixture straight from the freezer.
Is this baked oats recipe a healthy option?
Definitely! Let’s take a closer look at some of the key ingredients!
- Rolled oats – Oats contain both soluble and insoluble fibre which can help lower cholesterol and stabilize blood sugar levels, while also keeping you feeling full for longer. Not to mention, they can also improve your digestive health and keep you regular!
- Blueberries – Are jam-packed with antioxidants and phytochemicals that may help prevent and slow the progression of chronic disease and aging. Sign me up!
- Almond Butter – Contains healthy fats which can help lower cholesterol and improve overall heart health. The extra dose of protein and fat also keeps you feeling full for longer!
- Applesauce – Acts as a natural sweetener so less added sugar is required. If you wish to avoid the added sugar in this recipe altogether, don’t add the quarter cup of maple syrup, and instead add one cup total unsweetened applesauce.
Seriously, can you go wrong with all of that goodness?!
I think not!
Serving Suggestions
You can bake the oatmeal up and serve it as is OR you can add some additional toppings to spruce it up even further!
Some of my favourite toppings are:
- Fresh blueberries (or sub in other berries)
- A drizzle of almond butter
- A sprinkle of sliced almonds
Those would be my top three picks but feel free to get creative and add whatever you prefer!
Recipe variations
- To make nut-free: Sub in pumpkin seed or sunflower seed butter for almond butter. You could also try using melted coconut oil too. Leave off the sliced almonds.
- To make dairy-free: Use a plant-based milk alternative such as almond milk or soy milk.
- To make it no-added sugar: Sub in 1/4 cup additional unsweetened applesauce (for a total of one cup applesauce) for the maple syrup.
- To make it vegan: Try subbing in chia or flax eggs for the eggs.
- Switch up the berries: You could also try adding raspberries, strawberries or blackberries.
