Like I mentioned above, we’re oatmeal people. If YKYKYK. Baked oatmeal is something I’ve been making since the early 2000’s and more recently, we tried the viral blended baked oatmeal and it just doesn’t get old! We first posted this recipe in 2019 and have since revised and rephotographed it!

This easy baked oatmeal recipe comes together with rolled oats, mashed banana, eggs, almond milk, a little maple syrup, and a pinch of cinnamon. Since we’re in our toddler era at home, we topped each quadrant with different toppings, which is so fun!

How to Make Baked Oatmeal (+ cups!)

Baked oatmeal is seriously so easy to make! The best part about this recipe is that everything is mixed together right in the casserole dish — no bowls required!

1. Mash banana & add wet ingredients: mash the banana on the bottom of the casserole dish and then add the wet ingredients. Mix to combine.
2. Add Dry Ingredients: add the dry ingredients and mix again.
3. Toppings: top your baked oatmeal with your favorite toppings.
4. Bake: Bake at 350ºF until fully cooked in the middle — about 30 minutes.

Turn Them in to Baked Oatmeal Cups!

Instead of a baking dish, line a muffin tin with liners. Give them a good spray with cooking spray and fill them 3/4 of the way full. Bake at 350ºF for 18-20 minutes.

Variations for Baked Oatmeal

Every baked oatmeal recipe deserves a few add-ins to really spice things up and make them unique. Here are some ideas:

• chocolate chips
• fresh or frozen fruit
• shredded coconut
• chopped nuts
• peanut butter

Can you use quick-cooking oats instead?

Yes! You can use both rolled oatmeal and quick cooking oatmeal in most baked oatmeal recipes.

Should baked oatmeal be refrigerated? 

While we suggest always refrigerating your baked oatmeal, it should be okay in the counter overnight. We do want to note that it will last much longer in the fridge than on the counter.

How to Store Baked Oatmeal

Once your baked oatmeal has fully cooled, we suggest slicing it into single servings and placing into a glass, airtight container. Same goes for the cups.

Store your baked oatmeal in the refrigerator for up to 5 days. While you can leave your baked oatmeal out overnight, they will last much longer in the fridge.
