- Try swapping blueberries for other fresh or frozen berries such as raspberries or blackberries.

Storage

FAQs
Can I use quick oats instead of rolled oats?
Quick oats can be used, but the texture will be softer and less chewy. Rolled oats give the best balance of heartiness and structure in baked oatmeal.
Can I prepare this recipe the night before?
Yes, you can assemble the ingredients in the baking dish and refrigerate overnight. Bake fresh in the morning, adding a few extra minutes to the baking time as needed.
