No better way to make breakfast than to make one that lasts for days, and this mixed berry baked oatmeal does exactly that. Made with fresh or frozen berries, this mixed berry baked oatmeal is a great make-ahead breakfast for busy mornings.

If you like oatmeal but don’t have time to stand over a hot stove on busy weekday mornings, this mixed berry baked oatmeal recipe is perfect for you! One slice of baked oatmeal is the equivalent of one bowl of oatmeal, it’s just baked, making it a healthy and filling breakfast to ensure you’re fueled and full for the day ahead.
To ensure this berry baked oatmeal recipe is delicious and nutritious, I opted to sweeten it with natural sugars from a combination of berries, maple syrup, and a little cinnamon. For this reason, it’s not overly sweet, however, you can add a little extra flavor and sweetness once it is baked by serving it with milk or yogurt, a sprinkle of cinnamon, and/or an extra drizzle of maple syrup help to make it a sweet and delicious morning meal.

FAQs
Yes, baked oats are a healthy breakfast choice. Baked oats are made of oats, which are whole grains rich in fiber, vitamins, and minerals. When paired with fruit and a source of protein, baked oats can be a healthy and balanced meal.
Baked oatmeal is high in carbs given the primary ingredient is rolled oats, which is a source of carbohydrates. However, oats are a source of complex carbohydrates and are high in fiber, which helps to balance blood sugar, aid in digestion, and increase levels of satiety.
The most common reason for baked oats being mushy is undercooking. Fully cooked oatmeal should be brown on top and around the edges. To ensure your baked oats are not soggy or mushy, check for doneness by inserting a knife into the center of the baked oatmeal to see if has set. If the knife comes out clean, they’re done, if the knife comes out wet, it needs more time in the oven.
Absolutely. Baked oatmeal is a healthy snack on its own or paired with a source of protein and fruit for a healthy sweet snack.

Storage + Reheating
To Store: Allow the baked oatmeal to cool completely and then cover with aluminum foil or plastic wrap or transfer it to an airtight container and store in the fridge for up to 5 days.
To Freeze: Once cooled, baked oatmeal can be frozen for up to 3 months. To freeze whole, cover the baking dish with plastic wrap and/or aluminum foil and then place the entire baking dish in a freezer-safe bag. To freeze leftovers or individual portions, transfer the baked oatmeal to an airtight container and place it in the freezer.
To Reheat: To reheat the baked oatmeal whole, allow it to thaw completely, and then cover the baking dish with aluminum foil and warm it in the oven at 350°F for 10-15 minutes. To reheat individual portions, place a thawed portion in an oven-proof baking dish in the oven for 5-10 minutes or in the microwave in a microwave-safe dish for 1-2 minutes.

I love this baked oatmeal dish and make it regularly. It’s a really tasty, comforting and filling breakfast. That being said I’ve also eaten it for a pre/post workout snack too.
Delicious recipe. I mixed the berries in the oatmeal rather than on top. Yeah I’m a rebel.
I have started making a large pan of these for my family on a weekly basis. We all love it! I recommend it to everyone!! Even the 2 year old!
One thing I have a question about is if anyone had experience with doubling it and it taking on too much of an “egg” flavor because of it being 2 eggs instead of one. I’m wondering if I can just do one instead of two without it messing up the consistency.
I’m so happy you and the family enjoy it, thank you so much for sharing! Doubling the recipe shouldn’t alter the flavour as the ratios remain the same. 🙂
I love making this ahead & heating it in microwave . Very. Very tasty!
As it’s so hot now can I cook in the crockpot?
If so, your recommendations
So happy you like it! I have not tested it in the crockpot but I’m sure it can be done!
Yes, I doubled it when I made it for the first time tonight & it definitely had a very eggy flavor. I’ll see what the real critics think tomorrow morning 🤞
I have a milk allergy. How can I make these recipes accordingly?
The instructions to make the recipe dairy-free are noted in the post. 🙂 Specifically, use non-dairy milk such as almond milk or coconut milk and swap the butter for coconut oil.
Hy, I Will like to now if this meals are good for
People with diabetes.
I would recommend speaking with your doctor or dietician for personalized nutrition recommendations. 🙂
I made this with blueberries and raspberries. Added yogurt with a few slices of banana on top and sprinkled with chopped pecans. Tasted like dessert for breakfast. Very filling and delicious! Makes a generous 6 servings. Loved it!

Great snack and breakfast item especially when craving a little sweet without too much sugar. My eleven year old son loves them too!
Thank you for sharing, Karen!
This is my favorite breakfast now!!! It is so quick and easy to make and the flavors are amazing. It really fills me up too.
This recipe is an absolute gem! Tasty, comforting, filling…and easy to make! I love how I can make a week’s worth of breakfasts in one go as well. Sometimes it’s hard to believe it’s so healthy!
After storing this inthe refrigerator, do you eat it cold or do you reheat it in the microwave?
You can reheat it in the microwave or eat it cold, both options work!
I am eating a slice of this as I type. I am diabetic so to make the recipe lower in carbs, I substituted unsweetened almond mik and instead of regular maple syrup I used sugar free which brought the carb count down to 34 carbs instead of 49 per serving. The only disadvantage was that I also lowered Protein so I ate it with a generous dollop of unsweetened greek yogurt and cinnamon on top. It is pretty good and an easy fix for breakfasts as I usually don’t feel like making anything to eat in the am.I am refrigerating the remaining 5 servings to use for the coming week. I am eating it at room temp so I am curious as to whether It will taste good when cold. Thanks for this recipe.
I’m so happy you enjoyed it, Dolores! Thank you so much for your sharing your tips as well, they are much appreciated. 🙂
Been using the recipe for years now! We love it so much and change up the fruit depending on what we have in the house!
Thank you!
So happy to hear it, thank you for sharing, Tierza!
Easy and DELISH!!
It’s a 10/10 in my house.
