How to Make Baked Oatmeal

For the full recipe, scroll down to the recipe card for a list of ingredients and instructions.

Prepare rhubarb

Chop your rhubarb into bite-sized pieces and then transfer into a medium bowl. Drizzle on some honey and let that sit while you prepare the rest of the recipe. This will help take away some of the natural tartness of the rhubarb!

Mix together all ingredients

Mash your banana in a large bowl and then add the rest of the wet ingredients and stir. Then, slowly add all of the dry ingredients to the same bowl and whisk everything together.

Transfer into casserole dish

Transfer baked oatmeal batter into the prepared baking dish and spread out evenly. Then, decorate the top as you wish. We loved adding a few slices of strawberries because it makes your breakfast a piece of art!

Bake at 350ºF 

Bake at 350ºF for about 35 minutes or until the baked oatmeal has firmed up.
