Can You Make Baked Oatmeal with Greek Yogurt?
Yes. Greek yogurt works well in baked oatmeal because it adds moisture, creaminess, and protein while the oats provide texture and fiber.

Frequently Asked Questions
Can I prepare Greek yogurt baked oatmeal the night before?
Yes. You can mix the ingredients in advance and refrigerate the unbaked mixture in a covered dish, then bake it the next morning. Stir gently if the oats have absorbed some liquid.
Can I make baked oatmeal without protein powder?
Yes, but protein powder contributes both protein and dry ingredients in this specific recipe. Omitting it may change the texture and baking time. A tested substitution is best rather than leaving it out without replacing it.
How should I store leftover baked oatmeal?
Cool it promptly, divide into airtight containers, and refrigerate. Reheat individual portions until hot throughout, and add a spoonful of Greek yogurt or berries when serving.
