Make ahead breakfasts are just the best. Baked oatmeal is a regular on our breakfast table, because it’s just so easy and convenient!

Don’t worry if you didn’t plan ahead – you can either let these sit in the fridge overnight or bake them right away. Perfect for meal prep breakfasts, as they are great to make ahead and also freezer friendly.

My kids absolutely love these, and they’re great as a grab and go breakfast for busy school mornings!

Ingredient notes

Oats: I recommend regular rolled oats. If you want to use quick oats, you’ll need to add a couple of tablespoons extra and the oatmeal will be a little different in texture. Steel cut oats do not work.
Honey: A mild, runny honey works best here. You can also use maple syrup instead.
Brown sugar: If you want to make these refined sugar free, leave out the brown sugar and add an extra tablespoon of honey instead.
Milk: Any milk works – whole, skim, almond… Pick your favorite.
Oil: I like using melted coconut oil here, but you can also use a neutral vegetable oil or melted butter.
