Nothing says cozy mornings like a warm, fluffy pan of easy baked oatmeal!! Whether you’re feeding hungry kids, looking for a healthy breakfast, or prepping meals for the week, this baked oatmeal is the ultimate solution. It’s creamy, naturally sweetened, and packed with fiber to keep you full until lunch.

As a nutritionist, I love sharing breakfasts that are both nutritious and delicious, and this baked oatmeal hits the mark every time!! Even my kids, who usually prefer cereal or yogurt, beg for a slice. With just a few simple ingredients and endless flavor options, you’ll see why this recipe is one of my go-to breakfasts for busy mornings or lazy weekends alike.
Even though I usually start my mornings with eggs or smoothies like my protein-packed Instant Pot Egg Bites or my favorite smoothie, my kids often want something different. They love cereal, yogurt, or oatmeal, and this baked oatmeal hits the perfect balance between healthy and kid-approved!
This baked oatmeal has the best texture: rich, creamy, and fluffy, with a slightly firm top to hold it together. And the best part is it’s naturally sweetened without refined sugar.

Which Oats Are Best?
There are three main types of oats to choose from:
- Rolled Old Fashioned Oats: These are perfect for baked oatmeal! Steamed and flattened, they create a chewy, tender texture without getting mushy.
- Steel Cut Oats: Chopped oat groats with a steel blade, steel cut oats are hearty and nutty, but take longer to cook and stay firmer.
- Instant or Quick Oats: Pre-cooked and chopped, these oats cook fast but often end up mushy.
While steel cut oats have slightly more fiber and a lower glycemic index, rolled oats are still a nutritious and delicious choice for breakfast!

How to Make Easy Baked Oatmeal
Baked oatmeal could not be simpler! Here’s what you’ll need:
- Rolled Old Fashioned Oats – the best texture for baked oatmeal
- Milk – any dairy or non-dairy milk works
- Eggs – the glue that holds it together and gives it structure
- Sweetener – maple syrup, coconut sugar, or honey (I prefer maple syrup!)
- Ripe Bananas or Applesauce – adds natural sweetness and texture
- Vanilla Extract – for a hint of warmth and flavor
- Baking Powder – creates a light, fluffy texture
Simply mix all ingredients in a large bowl, fold in any flavor additions, and bake at 350°F in a 9×9 inch pan for about 35 minutes. That’s it!!

Flavor Ideas
While the base recipe is amazing on its own, here are some fun flavor variations to try:
- Banana Bread Baked Oatmeal: Add an extra ripe banana, cinnamon, nutmeg, and chopped pecans or walnuts.
- Blueberry Baked Oatmeal: Kids love this one! Use one banana and 1.5 cups frozen blueberries (no need to thaw). Add sliced almonds if you like.
- Apple Cinnamon Raisin: Swap bananas for applesauce, toss in diced apples, raisins, and cinnamon. You can also mix banana with applesauce for extra sweetness.
Feel free to get creative with other mix-ins like pumpkin puree, chocolate chips, or dried cranberries!


Storing and Reheating
Baked oatmeal is perfect for meal prep! Cut into squares after cooling. Wrap individually or store in an airtight container.
- Refrigerate: Heat in the microwave about one minute and serve with extra maple syrup.
- Freeze: Defrost in the microwave or at room temperature, then heat before serving.
This easy baked oatmeal will quickly become a breakfast favorite for the whole family!!!

Huge hit! When you substitute applesauce for the one banana on the apple raisin variety, how much applesauce? Had a banana so went w/ that & its delicious, but want to try applesauce next time.
1 cup of applesauce!
Amy, please tell me the nutrition information. Need a good keto oatmeal recipe!
Thanks so much! Best recipes ever!!
Hi Mary Beth! The nutrition information is in the bottom of the recipe card. This is not a keto friendly oatmeal. But I do have a few options you might like! Try my Savory N’Oatmeal bowls (https://www.wholesomelicious.com/savory-breakfast-noatmeal-paleo-whole30/) or my Blueberry Breakfast Bake without the banana (https://www.wholesomelicious.com/blueberry-breakfast-bake/)
Quick, easy, and delicious. I will definitely make again.
Great breakfast recipe . Love that you have 3 choices to choose from. I might even create a pumpkin spice one and add pecans.
Thank you, Susan! And I agree, a pumpkin would be delicious!
