Recipe At a Glance
Cuisine Inspiration: American
Primary Cooking Method: Oven
Dietary Info: Vegan and gluten-free (with certified GF oats)
Key Flavor: Slightly sweet
Skill Level: Beginner
Summary
- Hearty and filling: With fiber-filled and protein-rich ingredients like oats, flaxseed, and pecans, baked oats make a satiating breakfast.
- Healthy blueberries: Blueberries are a great source of vitamin C and other vitamins, antioxidants, and minerals.
- Plant-based: If you’re looking for a vegan baked oatmeal recipe, this one is entirely plant-based!
- Easy prep and clean-up: Mixing the ingredients right in the casserole dish means fewer dishes to wash–just the baking dish and the small bowl used for the wet ingredients.
Ingredients to Make Blueberry Baked Oatmeal
- Blueberries: You can use fresh or frozen blueberries. There’s no need to thaw the blueberries in advance. In fact, you’ll want to avoid that. Doing so may turn the whole dish to a purple color as the thawed blueberries mix with the liquid.
- Oats: Use old-fashioned rolled oats for this baked oatmeal. If you eat gluten-free, check to make sure your oats are gluten-free certified.
- Pecans: I like to add pecans for texture. Walnuts are another great addition or try candied walnuts for a sweet, crunchy bite.
- Cinnamon: A little cinnamon adds a nice sweetness and pairs well with the blueberries.
- Baking powder: This helps to lighten the oatmeal breakfast bake so that it is not too stodgy.
- Salt: Salt helps to balance the sweetness of the maple syrup and blueberries.
- Milk: I use unsweetened almond milk to keep this oatmeal breakfast bake dairy-free and vegan. You can make this with another plant-based milk or dairy milk if you prefer.
- Pure maple syrup: Sweetens the oatmeal naturally. You can also use honey, but keep in mind the recipe will no longer be vegan.
- Flaxseed: I like to add ground flaxseed to my oatmeal for some healthy omega-3s. It also helps to hold the baked oatmeal together.
- Coconut oil: To help bind the ingredients together.
- Vanilla extract: For vanilla flavor that pairs so well with the blueberries and cinnamon.
Popular Substitutions & Additions
This blueberry baked oatmeal recipe is so easy to adapt! Here are some ways to switch it up:
- Change the fruit: The blueberries can easily be swapped for other berries like strawberries, blackberries, or raspberries. Or use all the berries for a mixed berry oatmeal! Diced apples or peaches are great, too. You can even do half blueberries and half bananas if you’d like. Frozen fruit works too, and there’s no need to thaw it in advance.
- Change the nuts: Instead of pecans, try it with walnuts, almonds, hazelnuts, pistachios or cashews. It’s a good idea to chop the nuts, so they blend well with the other ingredients.
- Change or omit the sweetener: I only use a little maple syrup to offset the tartness of the blueberries, but you can swap it out for honey, agave syrup, brown sugar or stevia. If you’re using sweeter fruits like bananas or peaches, for example, you can leave out the sweetener all together.
How to make blueberry baked oatmeal
- Add the oats, pecans, cinnamon, baking powder, and salt to the baking dish and stir to combine.
- In a small bowl, whisk together the almond milk, maple syrup, flaxseed, coconut oil, and vanilla. Pour over the oats and mix.
- Add the blueberries, gently pressing them down to make sure they’re submerged.
- Bake until no longer jiggly and the top of the oatmeal is golden brown.
Tips for making the best blueberry baked oats
- Don’t use quick oats. Quick oats are chopped into finer pieces, so they cook faster and soak up more moisture than thicker old-fashioned rolled oats. This makes for a dry-baked oatmeal, so I don’t recommend them.
- Do not mix the oats with milk ahead of time. If you want to make these oats ahead of time, I recommend keeping the wet and dry ingredients separate, then combining them in the baking dish right before baking. Otherwise, the oats will soak up all of the liquid beforehand and the texture will be dry.
- Keep liquid ingredients at room temperature before combining. If the milk and maple syrup are cold, the melted coconut oil will solidify when it comes in contact with them. Having the ingredients at room temperature helps with the blending process. If the coconut oil still solidifies, just microwave the combined wet ingredients for 15-30 seconds until the coconut oil melts again.
- Double the recipe for a bigger crowd. Breakfast baked oatmeal is great for doubling to feed a big, hungry crowd! Just double the ingredient quantities, use a large baking dish, and add about 10 minutes to the baking time.
How to Store & Reheat Blueberry Baked Oatmeal
This baked oatmeal recipe is great for meal prepping. Store it in an airtight container in the refrigerator, then you can reheat individual portions in the microwave for 30-45 seconds before serving.
How Long Will Blueberry Baked Oatmeal Last in the Fridge?
It will last for up to 5 days in the refrigerator.
Can I Freeze Oatmeal Breakfast Bake?
Yes, blueberry baked oatmeal freezes really well! Allow it to cool completely, then store in individual portions in freezer-safe bags or containers. Reheat individual portions in the microwave for about one minute along with tablespoon of water or milk.
Frequently asked questions
Yes! I use an 8×11 baking dish, but you can use a pan as small as 8×8 or as large as 9×13. Note that a smaller pan may take longer to cook and will yield thicker slices, while a larger pan may take a shorter amount of time to bake and result in thinner slices.
Yes! The flax is used for added nutrition and to help bind the ingredients together; an egg will have the same effect.
Yes! If you prefer a sweeter baked oatmeal recipe, you can add more maple syrup to the ingredients, and/or drizzle maple syrup over the top of individual portions.
For a wholesome, delicious breakfast that is so easy to make and feeds a crowd, Blueberry Baked Oatmeal has you covered. It’s perfect for meal-prep, reheats easily, is packed full of nutrients, and tastes so good!
