FAQs
Can I use steel-cut oats instead of rolled oats?
Steel-cut oats have a chewier texture and require longer cooking times, so they’re not ideal for this baked oatmeal. Stick to old-fashioned rolled oats for the best results.
Can I make this recipe vegan?
Yes! This recipe is naturally vegan if you use plant-based milk like almond or oat milk and ensure your maple syrup is pure. No eggs or dairy are involved here.
