Ingredients for Blueberry Baked Oatmeal

- Ground cinnamon – get the best prices on spices and seasoning through Thrive Market!
- Ground nutmeg – adds a delicious and warm flavor. Feel free to omit if you don’t have it on hand or add ground ginger instead.
- Chia seeds – an optional ingredient that adds a boost of fiber. Feel free to omit.
- Maple syrup – may substitute honey.
- Ripe banana – a black-spotted banana works best in this recipe. You can also use applesauce.
- Eggs – To make this egg-free, mix 2 tablespoon flax meal + 6 tablespoons water in a small bowl. Let stand for 5-10 minutes before using in place of the eggs in this recipe.
- Milk of choice – any milk will get the job done. Organic cows milk, unsweetened almond milk, and even kefir works, too! For a non-dairy, nut-free milk use flax, oat, or hemp.
- Unsalted Butter – for dairy-free use coconut oil.
- Pure vanilla extract
- Almonds – Feel free to use any nuts of choice – we like to use sliced almonds but pecans also make for a very tasty addition. Omit for nut-free.

How to make Blueberry Baked Oatmeal
A one-bowl kind of a recipe makes for a quick clean up!
- Preheat the oven to 375℉. Spray a 9×9 or 8×8-inch baking dish with cooking oil spray or grease with butter or coconut oil.
- In a bowl, combine all of the ingredients and mix.
- Transfer to the baking dish. Top with a few additional frozen berries and sliced almonds, if desired.
- Bake for 30-35 minutes or until center is set.
- Let it sit for 10 minutes before serving.
- Top with whipped topping or plain yogurt and a drizzle of maple syrup if you please.
Can you freeze Baked Oatmeal?
Absolutely. Oatmeal bakes are perfect for freezing and enjoying as a future meal. We love to double the recipe and stash one away in the freezer. You can also make them into oatmeal cup muffins as we did in our Zucchini Banana Baked Oatmeal Cups.
How to Make this Baked Oatmeal Egg-Free
To make this baked oatmeal egg-free, simply replace the egg(s) with ‘flax eggs’ in the recipe and bake as directed.
To make a ‘flax egg’, combine 1 tablespoon ground flax meal and 3 tablespoons water in a small bowl. Stir well and let stand 5-10 minutes to thicken then add to the recipe in place of the eggs.
Double this if the recipe calls for 2 eggs.
Can fresh blueberries be used instead of frozen?
You sure can. We have tested this recipe with fresh blueberries and frozen blueberries and both work great. In fact, you can use any berries you like or have on hand. Strawberries, blackberries, raspberries, or a mix like we did in our Mixed Berry Baked Oatmeal recipe.
How to make Blueberry Baked Oatmeal nut-free and dairy-free
Simply omit the almonds for a nut-free option. For dairy-free, we like to use unsweetened almond milk and melted coconut oil in place of the butter.

Can you prep this the night before? If so, do you need to add more liquid to it with the oats soaking it up?
Stacie Hassing says
Hi Anne, we haven’t specifically experimented with that method so we can’t say for certain how it would turn out. This is a great meal prep, and it works well to make and then store in an airtight container in the fridge for up to 1 week or in the freezer for up to 3 months. To reheat – microwave for 30-60 seconds or in the oven at 300 degrees until warm.

This recipe is absolutely delicious!!! I used a half cup of brown sugar Splenda instead of honey. I also added walnuts rather than almonds. I will be making this again!!!!
Cassie P says
I greatly enjoyed this recipe for Healthy Blueberry Baked Oatmeal!
I included the chia seeds, substituted pumpkin pie spice for nutmeg, reduced maple syrup from 1/3 cup to 1/4 cup, used unsweetened soy milk & unsalted butter. Large 8″ banana came out to ~1/2 cup + 1 Tbsp mashed. Chopped almonds into fourths.
Batter was quite liquidy when poured into 8×8 pan. (It was helpful to watch the recipe video to see what textures were at different times.) At 30 mins, there were dime-sized pools of liquid atop batter so back in oven for 5 mins. At 35 mins, liquid was absorbed but there were wet bubbles popping on the surface. Baked for 3 more mins. Oatmeal was nicely browned as in website pictures; no wet bubbles. Checked with instant-read thermometer: all areas checked were 180 degrees F or higher. Let cool for 10+ mins.
Resulting baked oatmeal was delicious & moist like a bread pudding. Dark yellow banana was ripe & sweet but not yet speckled. I’m glad I reduced the maple syrup to 1/4 cup, that plus the banana resulted in a nice level of sweetness for me. Ingredients held together well, not crumbly nor gooey. I enjoyed the baked oatmeal as is without adding other toppings. Thank you for the recipe!

Great recipe! I’ve made it twice now for just my husband and I. Last week we went camping and I took it in individual servings that we reheated in a skillet on the camp stove! Delicious!

Thank you so much Deretta! We appreciate the 5-star review!
Paula says
Excellent not too sweet! I didn’t have enough blueberries so added blackberries. Walnuts added a great crunch!
