Easy baked oatmeal + all the best baked oatmeal recipes in one place, with a flavor for every season and occasion! Baked oatmeal is perfect for meal prep and so delicious.

I’ve been sharing one baked oatmeal recipe a month for over a year! I’ve had so much fun coming up with creative flavors and you love making them so it’s a win, win!

Why Baked Oatmeal?

I honestly LOVE all types of oatmeal (and I have a ton of oatmeal recipes here on EBF), but baked oatmeal is definitely one of my favorite ways to enjoy oatmeal. Here’s why:

  1. Topping the list is the fact that it’s the perfect meal prep recipe, but also fancy enough for a brunch. I love making baked oatmeal on the weekend and enjoying it for breakfast all week long.
  2. You only need one mixing bowl and one baking dish for these recipes. Minimal dishes? Score.
  3. The flavor combinations are endless! As you can tell, I’ve shared 14 flavor combinations so far and I don’t see myself slowing down anytime soon.
  4. While many of the baked oatmeal recipes sound indulgent, all of the ingredients in my baked oatmeal recipes are wholesome, nutritious ingredients.
  5. They can be allergen friendly. Sensitive to dairy? Use a dairy-free milk. Need to make vegan? Swap in a flaxseed egg in place of a traditional egg. Gluten-free? Check!

How to Store and Reheat Baked Oatmeal

You can store baked oatmeal in airtight containers in the refrigerator for 4-5 days or in the freezer for up to 3 months. When freezing, I recommend cutting the oatmeal into portions, wrap in plastic wrap and place the portions in a large freezer bag. The individual servings make it easier for reheating. 

To reheat the entire pan of baked oatmeal: cover with foil and reheat in the oven at 350ºF for about 20 minutes or until warm. For individual portions: set oven or toaster oven to 350ºF and bake for 5-10 minutes. You can also reheat in the microwave for 1 minute. Once warm, add your toppings and enjoy!

Do I Need to Use Baking Powder for Baked Oatmeal?

Baking powder is a rising agent and helps lighten the texture of the baked oatmeal. It prevents it from becoming too dense or heavy. That said, if you don’t have baking powder or simply want to skip it, you certainly can.

Notes and Substitutions

  • Egg – 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 – A lot of my baked oatmeal recipes call for melted coconut oil, but you can skip it or swap it with another oil, melted butter (or ghee) or even applesauce or mashed banana.
  • Bananas – Don’t love bananas? Try using applesauce, pumpkin or mashed sweet potato instead of the mashed bananas. 

Baked Oatmeal Turned Out Too Soggy?

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.

Can I Add Protein Powder To Baked Oatmeal

I’ve added a scoop of protein powder without adding in more liquid and it turned out just fine! If you’re adding more than one scoop of protein powder you might want to add more liquid.

Can You Swap Rolled Oats For Steel Cut Oats or Quick Oats?

You can use steel cut or quick/instant oats for baked oatmeal, but you need to follow a recipe that calls for those oats because the liquid ratio is different. I do have an apple cinnamon baked steel cut oatmeal recipe I would suggest if you’re looking for a recipe that calls for steel cut oats. 

The Perfect Ratio

Customize your own baked oatmeal but make sure you keep the ratio of liquid to oats the same. For most recipes you’ll use 1 part oats to 1 part liquid. I prefer to use unsweetened almond milk, oat milk or coconut milk but any milk works!

Can You Make Baked Oatmeal Ahead of Time?

Yes, you can totally make baked oatmeal ahead of time. There are a couple options that work really well.

Option 1: Bake and Then Reheat Before Serving

  1. Prepare baked oatmeal as the recipe suggests. Once baked, let the oatmeal cool, cover the baking dish and place in the fridge. You can do this 1-2 days in advance. When ready to serve, take oatmeal dish from fridge, cover with foil and reheat in a 350°F oven for about 20 minutes. For individual portions, set toaster oven to 350°F and bake for 5-10 minutes or reheat in the microwave for 1 minute.

Option 2: Prep as Much as You Can Without Baking

  1. Mix together your dry ingredients in a bowl, cover and let sit out on the counter until morning.
  2. Mix together all the wet ingredients in another bowl, cover and store in the fridge until morning.
  3. In the morning, simply mix the wet and dry ingredients together, pour oatmeal mixture into your prepared baking dish and bake as recipe suggests.

  1. Hi! Looking forward to trying this recipe, I’m allergic to coconut so wondering what would you recommend as a coconut oil substitute?

    1. Yay! I’m so glad you loved this recipe. Thanks for making it and for coming back to leave a comment + star rating. I so appreciate it!

  2. 5 stars
    Super yummy! My first time making baked oatmeal. I used walnuts and pecans, and left out the sugar, vanilla and cinnamon (I don’t normally sweeten my oatmeal) and it was delicious! An extra pat of butter and it was like oatmeal banana bread.

    1. YUM! Sounds so delicious, I am glad that you are enjoying this recipe, Andrea. Thank you for coming back and sharing your review & star rating, I really appreciate it.

  3. 5 stars
    Great post! I love how you included so many different flavor options for baked oatmeal. I especially can’t wait to try the Peach and Samoa flavors. I also appreciate the tips on how to store and reheat the oatmeal, as well as the substitution options for those with dietary restrictions. Thanks for sharing all your knowledge and expertise on this recipe, I can’t wait to make my first batch of baked oatmeal!

    1. Of course! I so glad that you found this post helpful. Let me know how you like these recipes and which one you try first. Enjoy!

  4. This recipe calls for 2 cups of milk. Is that meant to be 1/2 cup like the other recipes or is it actually 2 cups?

    1. Hi Rose-Mary – You will want to use 2 cups of milk for this recipe. I recommend using equal parts oats & milk. Hope this helps and you enjoy this recipe.

    1. Ah YAY! I am excited to hear that this recipe is a hit for the whole family, Andy! Thank you so much for sharing your review + star rating, I really appreciate it!

  5. 5 stars
    I have been eating this for months as my lunch. Super easy to make. I tend to use protein shakes as my milk substitute and I find when I add coconut or nuts I need to add more milk as it comes out a little drier. also tried with brown sugar instead of maple syrup when I ran out. That tastes good too. Thanks so much for coming up with this easy great meal.

    1. Aw yay, this means so much to me! I am excited to hear you’re loving this recipe. Thank you for coming back and sharing your review & star rating, I really appreciate it!
