Healthy Baked Oatmeal

Baked Oatmeal

I am so excited about this healthy baked oatmeal recipe! Who doesn’t love the combination of peanut butter, banana, and chocolate chips baked into an ooey-gooey fiber rich breakfast bake? It’s a super simple one-bowl recipe and can easily be made ahead of time, though we do think it is SO TASTY straight from the oven too.

This oatmeal bake is based off of our popular Oatmeal Cups recipe so it has the perfect almond milk (or milk of choice) to oats ratio.Baked Oatmeal

I’ve been using Enjoy Life Foods chocolate for YEARS! All their products are specially made to be free from gluten and the 14 most common food allergens – wheat, peanuts, tree nuts, dairy, casein, soy, egg, sesame, sulfites, lupin, mustard, fish, shellfish & crustaceans. They even make all of products in a special allergy friendly facility, which is pretty great. Plus, the chocolate is delicious! I love the dark chocolate chips and the mini chocolate chips for all of our baking, especially this oatmeal!

How do you make baked oatmeal

  • Pour into your greased, or lined with parchment paper, baking dish.
  • Bake!

What Oats Should You Use

  • Use rolled oats, not quick cooking oats. If gluten-free, make sure you buy gluten-free rolled oats.
  • Can you bake instant oatmeal? The short answer is not really! Instant oatmeal is different than regular oatmeal because it is thinly cut, processed and flavored. They don’t lend the same structure to baked goods as regular oats or quick oats!
  • P.S. You can sub out for your favorite nut butter here, or to make it nut-free use sun butter.

Meal Prepping Your Baked Oatmeal

Bake it and eat some immediately and then pack the rest away for later. Store in the refrigerator in an airtight container for up to 4 days.

Can You Freeze Baked Oatmeal?

Yes! Once it is fully cooled, store in an airtight container for up to 3 months.

Reheating Instructions

Either defrost overnight in the refrigerator or give it a quick pass in the toaster oven or microwave to heat up!

Whole Tray: To reheat the of tray baked oatmeal, cover and bake at 350°F for about 20 minutes.

Individual Pieces: Bake in your oven or toaster oven at 350°F for 5-10 minutes until warmed to your liking, or reheat in the microwave for about 1 minute.

  1. Love these recipes Lexi. I have recently been diagnosed with CKD and would be grateful if you have any recipes for this condition. I know I have to be careful with potassium and phosphorous and particularly with sodium/salt.
    I feel like I am surviving on salads, fruit and veg—the plus side is the weight loss 😉
    Kind regards,

    1. Sorry to hear, Jan! you can find many recipes on the site that are likely friendly to CKD. You can always reduce / not sure salts to help with sodium in our recipes as well as reducing nuts and increasing potassium friendly foods.

  2. I made this last night and I’m already planning the pumpkin version next! I omitted the maple syrup and used cacao nibs instead of chocolate chips. Oh, and I used Ground Up Cinnamon Snickerdoodle almond & cashew butter. It’s really great texture, comes together so easily!

  3. This is my favorite baked oatmeal and I make it very often!
    Recently told I can’t have eggs. How can I make this without eggs???

    Due to a nut allergy, I swapped the peanut butter and almond milk for sunflower seed butter and regular milk. These were delicious!! My husband has even said how much he loves the taste. Such an easy, quick breakfast.

    Thank you so much for the recipe. My family loves this baked oatmeal. I followed the directions and it came out perfect.

  6. 5 stars
    Great! Easy to make, already have ingredients. I’ve tried other oatmeal bakes from other sites and they tend to come out dry or just not the right texture. This one was exactly what I was hoping for! Great flavor and texture. My daughter loved it too!

  7. 5 stars
    This dish is sooo yummy. It’s a bit more moist than I thought so it didn’t work as bars but I was very happy with the flavour and texture. We had it warm with some vanilla ice cream.
    I’m just not sure if it should be refrigerated or not

  8. 5 stars
    I make this weekly. I have had different combos and it always turns out great; almond butter/peanut butter, honey/maple syrup. It’s always delicious. 🙂 reheats great from frozen, too. Thanks for introducing me to oatmeal bakes.

  9. 5 stars
    This already has a ton of reviews, but I always comment on all of the LCK recipes I make 🙂 Worth repeating that it’s simple and quick to make, and yummy for the whole fam. I omitted chocolate chips and it was still great!

  10. 5 stars
    This was so delicious the first time i made it (and disappeared so quickly), I went ahead and doubled the recipe the second time around 🙂

      1. Glad you love it! You’ll see in the post it says to store in the refrigerator in an airtight container for up to 4 days.

    She did it again! Another delicious recipe! Super easy to throw together this morning for me and my kids. They loved it, too, which is of course a huge plus! Thanks, Lexi!
