Baked Oatmeal Recipe: Ingredients & Substitutions 

This baked oats recipe is extremely versatile. You can tweak it to fit just about any dietary need and it still comes out amazing. 

• Old-fashioned oats. Quick-cooking oats also work well in this recipe, just decrease the amount by 1/4 cup (so use 2 1/4 cups quick-cooking oats). Note that the texture will be a little lighter and less chewy. 
• All-purpose flour. Gluten-free all-purpose flour can be used for a gluten-free variety. Whole wheat flour, spelt flour, etc. also taste great. 
• Butter. I love the buttery flavor of this baked oatmeal, however you can substitute coconut oil, ghee, vegan butter, etc. to make it dairy-free. 
• Applesauce. If you don’t have applesauce on hand you can substitute 1 cup of mashed banana. You can also try pumpkin, sweet potato, etc. however you may need to increase the sugar if you use an ingredient that isn’t naturally sweet. 
• Brown sugar. Any granulated sugar works well. I love the flavor of brown sugar but you can use white sugar, coconut sugar, etc. 
• Milk. Again, any milk can be used in this recipe. We use whole milk or almond milk, but 2%, coconut milk, etc. also work great. Just remember the higher the fat content of your milk variety, the richer and creamier the baked oatmeal will taste. 

How to make Baked Oatmeal

This baked oatmeal recipe is very easy to make, but as always we’ll walk through the process step-by-step. And don’t forget to watch the video!

Combine dry ingredients

The first step in this baked oatmeal recipe is to combine the dry ingredients. I prefer to do this for two reasons: 1) measuring dry ingredients first means you don’t have to wash the measuring cups/spoons after measuring the wet ingredients. 2) it ensures that the dry ingredients are evenly combined, and therefore will be evenly distributed in the baked oatmeal. 

Combine wet ingredients & sugar

Next, in a large bowl, whisk together eggs, melted butter, applesauce, vanilla and brown sugar until smooth. Make sure there are no lumps of brown sugar left in the mixture.  Then, add the milk and whisk to combine .

Combine dry & wet ingredients

Next, add the dry ingredients to the wet ingredients and stir until mixture is homogenous (uniform throughout). 

Bake

Once the batter is ready, pour it into an 8×8″ square baking dish and bake for about 30 minutes, or until the top is set and slightly puffed.  Then, let the baked oats cool on a wire rack for at least 20 minutes before serving. 

Serve

Once the baked oatmeal has cooled slightly, cut into squares and serve. For adult servings, cut it into 9 squares, for kid-sized servings 16 square is a great choice. 

We love eating this recipe with a drizzle of pure maple syrup and fresh berries! Other suggestions include:

• Enjoy it with a dollop of homemade whipped cream for an extra special treat. 
• Slather it with homemade peanut butter or vanilla almond butter for some extra protein and fat to keep you full even longer. 
• Spread some homemade cinnamon honey butter over your slice. 

To make the night before

You can make this recipe the night before in two ways:

1. Make the entire recipe and bake it the night before, then warm it in the morning by covering it with foil and heating it at 300 degrees F until warmed through.
2. Combine the wet ingredients in one bowl and the dry ingredients in another. Cover both bowls and store the wet ingredients in the refrigerator overnight. Combine them in the morning, pour into the baking dish and bake according to the recipe.

Store

Store leftover baked oatmeal in an airtight container in the refrigerator for up to 5 days. 

Freeze

This baked oatmeal recipe freezes beautifully. I recommend individually wrapping slices of the baked oatmeal in plastic wrap and storing them in an airtight container in the freezer. It will last for up to 2 months in the freezer. 

To reheat: 

You can reheat these baked oats in the microwave or in the oven set to 350 degrees F until the middle is warm. You can also remove a slice of baked oatmeal from the freezer and let it thaw in the refrigerator overnight.
