What is baked oatmeal?

Baked oatmeal is essentially oats that are mixed with an almost custard like mixture, often referred to as amish baked oatmeal, and gives you the most incredible soft and fluffy breakfast bake. The texture is nothing like the microwave packets we’ve all grown to love, but more like a spongy cake.

Best topped with a splash of milk or cream and your favorite berries, this recipe is sure to become a family favorite. AND you can even make it ahead of time!

Baked Oatmeal Breakfast

So, what exactly goes into a baked oatmeal breakfast? The answer might surprise you, as most are pantry staples you already have on hand! You could have this breakfast ready in no time!

  • Quick cooking oats- Rolled oats won’t soak up as much of the egg and milk mixture, leaving you with a slightly tougher finish.
  • Brown sugar- Optionally, you can substitute this with maple syrup. We prefer the traditional brown sugar oatmeal flavor.
  • Baking powder and salt- Be sure to double check the expiration date of the baking powder. Using fresh ingredients will make a difference.
  • Cinnamon- Just a dash goes a long way in boosting the flavor.
  • Eggs- Large eggs.
  • Milk – 2% is our go-to, however you could always substitute this for your favorite milk variety.
  • Butter- Another optional, but extremely tasty addition.
  • Blueberries (or other fruit)- Bake the fruit right in to the oats or offer them as a topping. We like to do the latter, since we all prefer different fruits in our breakfast.

Can you use non-dairy milk in baked oats?

Yes, you can use a non dairy milk like almond, oat, coconut, or rice milk in this recipe.

Tips and FAQs:

What type of oats should you use in baked oatmeal?

Quick oats work best in this recipe. We have made this recipe a few different times, testing both rolled and quick, and find that quick oats give a better texture to the finished oatmeal.

Can you freeze cooked oatmeal?

Another bonus to this dish is that you can FREEZE it. Can I get a hallelujah?
This is a huge time savor in the mornings. When you need a quick, filling, and somewhat healthy dish… All you need to do is stick this in the microwave and you are ready to chow!
1. Spoon your cooked oatmeal into freezer safe bags. Squeeze as much air as possible out and seal shut.
2. Label with the recipe name and date. Frozen oatmeal will stay fresh up to 6 months in the freezer.
3. When you are ready to eat your oatmeal – Transfer to a microwave safe bowl. Heat in 30 second intervals until warm.

How long does baked oatmeal keep?

Baked oatmeal will keep for up to 3 days when stored, covered, in the refrigerator.

Is baked oatmeal healthy?

It can be, yes. It all depends on your add-in options and substitutions.

Can you make this recipe the night before?

Absolutely, however I suggest adding just a 1/4 cup more milk to the mixture. Mix as directed and pour into the prepared pan. Cover and refrigerate overnight. Bake as directed.

Made this for breakfast this morning. I was VERY happy with how it turned out! We substituted strawberries for blueberries because that is what I had on hand. Will try it out with blueberries next time for sure!
