Recipe Notes
Oatmeal is very versatile, using your favorite fruit and nuts!
- Use whole old-fashioned oats for the best texture and optimal results.
- Blueberries can be fresh or frozen. If blueberries are not your thing, choose a different berry.
- Try a different nut! Swap out the almonds for pecans.
- The fat in whole milk helps hold the oatmeal together, but 2% works great, too!

Baked oatmeal is a really great go-to, especially if you have portions tucked away in the fridge for the busiest of mornings!

This sounds great. Can it be assembled the night before and baked in the morning?
Can’t see why not. Keep it cover tightly in the fridge and let it sit at room temperature for about 30 minutes before baking or you might need to increase the bake time by a few minutes.
Delicious! Super easy. I used almond milk, and it worked fine. Recipe is not too sweet, and I ate it plain. Great new way to eat oatmeal.
This was perfect! I used blackberries – whole family loved it.
