FAQs

Can I use quick oats instead of old-fashioned?
Old-fashioned oats give the best texture. Quick oats will make it mushy.

How long does baked oatmeal last?
Store covered in the refrigerator for up to 5 days. Reheat individual portions.

Can I freeze baked oatmeal?
Yes! Cut into squares, wrap individually, and freeze for up to 3 months.

Is this recipe gluten-free?
Use certified gluten-free oats to make it gluten-free.

Can I make this dairy-free?
Yes! Use your favorite plant-based milk and oil instead of butter.

Can I reduce the sweetener?
Yes, you can reduce the maple syrup to ¼ cup. The blueberries add natural sweetness.

What size baking dish should I use?
8x8 or 9x9 inch square dish works best. A 9-inch round pie dish also works.
