Ingredients

- Oats - rolled or old-fashioned oats will work best.
- Apple - Any variety will work! Our favorites are fuji and honey crisp (perfect apples for homemade applesauce). If you are using a tart apple, you will need to add banana or maple syrup to help balance the tartness.
- Chia seeds - For a boost of protein, fiber, and omega 3 fatty acids. Will also help thicken the oatmeal, like in this chia pudding.
- Milk - can use any milk of choice. My personal favorite is canned, full fat coconut milk.
- Cinnamon
- Banana, maple syrup, walnuts (optional): I wanted to keep the recipe as simple as possible, but you may certainly add these in if you desire a sweet oatmeal. See below for tips.
Step-by-Step Instructions

Grease the baking dish. First add the applesauce followed by the rest of the ingredients (minus the chopped apples). Stir to combine. Top with apples and walnuts, if using. Bake!
It's seriously as easy as that!
Tips for Success

Lightly grease the bottom and sides of the baking dish with oil to prevent sticking.
Add maple syrup for sweetness. The basic recipe with applesauce is not very sweet, and this is intentional as you can easily top with additional fruit and/or a drizzle of maple syrup. If looking for a no added sugar alternative, try this date syrup!
Babies also have a preference for sweets so it's great to use this "window of opportunity" for them to learn to appreciate other flavors.
But if you prefer a sweeter oatmeal, use a ripe banana instead of applesauce (not both) or maple syrup.
How to serve this oatmeal bake

Baked oatmeal can be enjoyed warm or cold.
For babies

Add finely chopped or grated instead of diced apples for safety.
Once baked, slice into strips or bite-sized pieces depending on their age. You can also break it up with a splash of milk and serve in a bowl, porridge-style.
Top with yogurt or thinned out peanut, nut, or seed butter.

Frequently Asked Questions
You can use quick oats but the oatmeal will be much softer. Steel cut oats will not work for this recipe.
I suggest leaving it on as it's where the majority of the nutrients are found.
Transfer to an airtight container and keep in the refrigerator for 4-5 days.
To freeze, cut into individual slices, wrap in plastic wrap, and place in a freezer-safe bag. It will be good for up to 3 months.

Love all your recipes! I'm excited to try this one but don't have a square pan - would a bread/loaf pan or silicone muffin cups work too?
Min says
Sure! Will just need to adjust the cooking time
Emily says
Love that this recipe is vegan…my baby is sensitive to egg & dairy so I’m always adapting recipes, but didn’t have to change this one at all! It’s a nice neutral tasting oatmeal, so sometimes I add peanut butter for a protein boost. Nice to have an easy, make ahead breakfast!
Min says
I'm so glad you enjoyed this recipe. For all my recipes, you can substitute with dairy-free alternatives and I will try to provide egg-free alternatives whenever I can!

Tina says
Hey Min, thank you for your wonderful and simple recipes! I've made several for my baby and they're always a hit! Iade the strawberry oatmeal and would love to make this one next. I am going on a trip for a few days and was wondering whether any of the muffin or oatmeal bake recipes might work without access to refrigeration? If not, do you have any suggestions of bakes that could work if stored at room temperature? Thanks!
Min says
Hi Tina, Will you be able to take a cooler? If so the muffins and this oatmeal will be great to take. I also have a post that may be helpful - search for "travel food" on my site!
Jacqueline says
Really easy to make and tastes pretty good!
How quickly do I need to refridgerate it? I made it late last night and forgot to put it in the fridge…
Min says
Hi! It should be fine although not sure what it's like texturally..
