Ingredients Needed

Old fashioned rolled oats – Quick oats work fine as well but will make the dish a bit denser.
Sugar – Readers have said they like swapping in brown sugar here.
Flaxseed – Why eat flaxseed?
Salt, baking powder, and cinnamon`
Nuts – Pecans, sunflower seeds, or walnuts are all great options.
Dried cranberries – You could use raisins instead.
Diced fresh fruit – Apples, pears, or peaches are my pick. But, banana, blueberries, or strawberries would work, too.
Coconut oil – Avocado oil is another healthy swap.
Eggs
Milk – I use whole milk, but a non-dairy version is totally fine.

How to Make Mixed Fruit Baked Oatmeal

Combine Dry Ingredients and Add Coconut Oil

In a large mixing bowl, combine the dry ingredients.

Drizzle the melted coconut oil over the dry ingredients and stir it around. This helps it get mixed into the batter without coagulating from the cold ingredients.

Add in the Fruit and Pecans

Gently stir in your fruit of choice. Just make sure it is diced up very small.

In this recipe, my favorites are apples, pears, or peaches.

Pecans are optional but add a little crunch and nutty flavor that goes well with all of the sweetness.

Serve warm in bowl with a little milk over the top.

How to Freeze Baked Oatmeal

We are big fan of freezer meals. In fact, we’ve worked hard to create valuable freezer meal resources for you–including two cookbooks, a library of 1 Hour Freezer Prep, and an index of tried and true freezer meal recipes.

Here’s the best way to freeze baked oatmeal:

Freeze For Later:

Assemble the baked oatmeal but don’t bake it. Tightly wrap the dish in a few layers of plastic wrap or foil (or a tight-fitting lid) and freeze.

Prepare From Frozen:

Thaw completely using one of these safe methods. Bake according to instructions.

FAQs

Can you prep Baked Oatmeal ahead of time?

Yes, you can prep baked oatmeal (unbaked) ahead of time and store it in the fridge for up to 5 days or in the freezer for up to 3-6 months. Thaw and bake per instructions.
You can also fully cook and cool the baked oatmeal ahead of time and store in the fridge for up to 5 days. Just rewarm individual portions in the microwave. Our readers have told us that they freeze fully cooked, individual portions of baked oatmeal in the freezer, as well, and rewarm in the microwave.

Can you use quick oats in baked oatmeal?

While you can use quick oats in baked oatmeal, it’s best to use rolled oats because they give the dish a heartier texture. Quick oats or instant oats can result in a denser, mushier result.

Baked oatmeal can be made gluten-free or dairy-free with these substitutions:
Dairy-Free Option: Use dairy-free milk in the recipe.
