What is Baked Oatmeal?
Baked oatmeal is healthy breakfast dish made by combining oats with a liquid, some sweeteners and flavorings and baking the mixture in the oven until it becomes firm and golden. The texture is similar to bread pudding and it’s really tasty and a fun way to switch things up from traditional stovetop oatmeal or overnight oats. There are a couple popular variations including the style I’m sharing here with rolled oats and another viral version called blended baked oats that bakes up similar to a cake!Why You’ll Love This Recipe
I personally LOVE all types of oatmeal (see all the oatmeal recipes here on EBF), but baked oatmeal is definitely one of my favorite ways to enjoy oatmeal. Here’s why:- It’s the perfect meal prep recipe. Quickly whip up a batch during your weekend meal prep and reheat it for breakfast all week long.
- You only need one mixing bowl and one baking dish. Minimal dishes? Score!
- The flavor combinations are endless! As you can tell, I’ve shared 20+ different baked oatmeal recipes and counting. There are so many ways to switch things up so your baked oatmeal never gets boring.
- It’s lightly sweetened with maple syrup and made with healthy, nutritious ingredients, but doesn’t taste super duper healthy (aka like cardboard).
- It’s allergen friendly. Sensitive to dairy? You can use a dairy-free milk. Need to make it vegan? Swap in a flaxseed egg in place of a traditional egg. Gluten-free? Just be sure your oats are certified gluten-free.
Ingredients Needed
- old fashioned rolled oats – be sure to used rolled oats, not quick oats. I like using these certified gluten-free oats from Bob’s Red Mill.
- baking powder – a rising agent that helps lighten the texture of the baked oatmeal. It prevents it from becoming too dense or heavy.
- ground cinnamon – cinnamon is the perfect warming spice for oatmeal, but you can also add more spices if you’d love. Ginger and nutmeg would be nice additions.
- sea salt – to bring all of the flavors together.
- unsweetened almond milk – any dairy-free milk works, but I like to use unsweetened vanilla almond milk. Dairy based milk works too if that’s what you have on hand.
- maple syrup – pure maple syrup is the perfect natural sweetener to use in my opinion! Just be sure to use pure maple syrup, not the artificial kind labeled “pancake syrup” and made from corn syrup… NOT the same!
- egg or flaxseed – this helps bind everything together. You can use a regular egg or ground flaxseed. If you’re using the flaxseed, no need to make a flax egg with water, you can just mix the ground flaxseed directly in with the rest of your ingredients.
- coconut oil – to add moisture and richness to the recipe. Nutiva organic extra virgin coconut oil is my favorite. If you don’t want to use coconut oil, butter works too!
- pure vanilla extract – a nice flavor enhancer.
- ripe bananas – sliced ripe bananas will act as a binding agent while providing plenty of sweetness. You can also use 1/2 cup applesauce instead of the bananas if you prefer.
- pecans – I used chopped pecans as the mix-in and topping for this recipe, which adds healthy fats, texture and protein.
I used chopped pecans as a mix-in and topping for this version, but feel free to get creative and use whatever mix-ins and toppings you prefer!
Step-By-Step Process
While there is a bit of cook time, this baked oatmeal is so easy to whip up in one bowl. Here’s the process: Step 1: Preheat your oven to 375° F and spray an 8×8 inch square baking dish with cooking spray. Step 2: In a large bowl, mix together the oats, baking powder, cinnamon and salt. Add in the milk, maple syrup, egg, coconut oil, vanilla and bananas. Stir to combine. Step 3: Add in 1 cup of chopped pecans to the oat mixture and mix to combine. Carefully pour the oatmeal mixture into the prepared baking dish and scatter the remaining pecans on top. Step 4: Placed oatmeal in the oven and bake for 35-40 minutes, until the top is nicely golden and a toothpick comes out clean. Step 5: Remove from the oven and let cool for a few minutes. Portion into 6 slices and serve. I love serving it with fresh berries and a drizzle of nut butter, but you can also drizzle on a little maple syrup if you want it a bit sweeter.Notes and Substitutions
Need to change up the recipe based on your dietary preferences or what you have on hand? No problem. Here are some tips for doing so!- Milk – Feel free to use whatever milk you have on hand… cow’s milk, soy milk, oat milk, almond milk, coconut milk or cashew milk. Any of these will work.
- Egg – Almost all of my baked oatmeal recipes either call for an egg or a flaxseed to bind the dish together. Eggs also help make the oatmeal creamy. You could also use chia seeds or skip the binder all together. I’ve found that the baked oatmeal still turns just fine without using the egg or flaxseed.
- Oil – You can skip the oil or swap it with another oil, melted butter (or ghee) or even applesauce or mashed banana.
- Bananas – Don’t love bananas? Swap it with 1/2 cup of applesauce, pumpkin or mashed sweet potato instead.
- Maple syrup – Any liquid sweetener like honey, agave, brown sugar or monk fruit maple syrup will work instead of maple syrup.
- Baking powder – If you don’t have baking powder or simply want to skip it, you certainly can. I’ve made baked oatmeal before without baking powder and its turned out just fine.
- Pecans – Feel free to swap the nuts with your favorite mix-in of choice. Fresh fruit, dried fruit, chocolate chips and nuts are all great options. You can use one mix-in or a few… it’s totally up to you!

Baked Oatmeal FAQ’s
Yes, baked oatmeal is a healthy breakfast option. There is a great balance of macronutrients – healthy fats from the egg, coconut oil and nuts, fiber from the oats, and lean protein from the egg.
All of my baked oatmeal recipes are a bit soft, but shouldn’t be too soggy. If a recipe calls for mashed bananas, make sure the mashed bananas aren’t overly ripe or that could add extra liquid. If yours turns out gooey or soggy, you might need to cook it longer.
Yes! Since this recipe is moist it should be stored covered in the fridge or freezer. If you store it at room temperature bacteria can grow quickly and spoil your oats.
You can use steel cut or quick oats for baked oatmeal, but you need to follow a recipe that specially calls for those types of oats because the liquid ratio is different. I do have a baked steel cut oatmeal recipe.
Yes! I’ve added a scoop of protein powder to my recipes without needing to add more liquid! If you’re adding more than one scoop of protein powder you might want to add more liquid. I recommend following my protein baked oatmeal recipe.
