Now, Let’s Get Cooking
- Preheat & Prepare: Start by preheating your oven to 375 degrees Fahrenheit and melt the butter in the microwave (set aside to cool). Then, lightly grease a 9 x 9 baking dish to ensure the oatmeal doesn’t stick (because it surely will).


- Mix: In a large bowl, combine all of the ingredients listed above. Mix until the ingredients are even and well incorporated. Don’t be shy – you’ve really got to get in there and give it an aggressive stir. *I photographed this in steps for the visual, but you can just add it all to the bowl at once.


- Bake: Once your oat mixture is ready, pour it into the prepared baking dish and smooth out the top. If you’re feeling fancy (which I hope you are!), press a few extra blueberries and pecans into the top. Then pop it into the oven and bake it for about 30 minutes or until the center is set and the top is a light golden brown.


- Rest: Let the baked oatmeal sit for about 10 minutes to cool slightly and set up before serving.
- Serve: Using a sharp knife or a large spoon slice or scoop the oatmeal into 9 equal servings. Then top it with a dollop of whipped cream, a spoonful of Greek yogurt, and/or or a generous drizzle of maple syrup or honey, and devour!

Substitutions and Variations
One of the things I love most about this recipe is its adaptability. And here are a few simple ways you can switch things up.
- Nut-Free: If you have a nut allergy or simply prefer to go without nuts, feel free to omit the pecans or substitute them with seeds like pumpkin or sunflower seeds for a similar crunch.
- Swap Nuts: If pecans aren’t your jam, experiment with different nuts such as almonds (I think sliced almonds would really make it next level), walnuts, or even hazelnuts.
- Swap Fruits: You can easily switch the blueberries out for other fruits like raspberries, strawberries, or even diced apples, peaches or pears for a seasonal twist. Really, anything goes.
- Spice it Up: Don’t be afraid to play around with the spices too. Add a pinch of ginger or cardamom for some extra warmth and flavor.
And if you LOVE blueberries as much as I do, try these Starbucks Blueberry Scones—they’re easy and delicious.
Tip
If you’re only feeding a couple of people, you can make a small-batch of this baked oatmeal. Just halve the recipe and bake it in a loaf pan instead. It makes 3-4 servings when prepared this way.

Tips for Storing & Meal Prepping Baked Oatmeal
Now, let’s talk about how to make the most of your blueberry pecan baked oatmeal.
- Storage: If you somehow manage to have leftovers (which is rare in my household), don’t worry. Simply store the baked oatmeal in an airtight container in the refrigerator. It should stay fresh for 3-5 days. Just reheat individual portions in the microwave or oven when you’re ready to enjoy it again.
- Meal Prepping: Want to make your mornings a breeze? Whip up a batch of this baked oatmeal on a Sunday afternoon and portion it out for the week ahead. Store the individual servings in individual containers or wrap them up in foil for a grab-and-go breakfast. Easy peasy.

This blueberry pecan baked oatmeal is a warm and comforting breakfast that’s as nutritious as it is delicious. With its quick prep, minimal dishes, and super cozy flavors, it’s sure to brighten your day and fuel you up for whatever comes your way. There’s really no better way get the day going, if you ask me. Happy baking, my friends.
