Pro Tips for the Best Results

Frequently Asked Questions (FAQs)

Can I use steel-cut oats instead of rolled oats?
No, steel-cut oats require much longer cooking and won’t yield the same texture. Stick with rolled oats for best results.

Can I make this recipe gluten-free?
Yes! Use certified gluten-free oats to ensure the dish is safe for those with gluten sensitivities.

How can I make it less sweet?
Reduce the maple syrup by half or omit it entirely, letting the natural sweetness of the apples shine.

Can I bake this in muffin tins?
Absolutely! Portion the batter into a greased muffin tin and bake for 20-25 minutes for single-serving portions.

Why is my baked oatmeal dry?
Overbaking can dry it out. Check for doneness a few minutes early and cover with foil if the top browns too quickly.
