I am so excited to share today’s Lemon Blueberry Baked Oatmeal recipe with you guys today! I am completely obsessed with making baked oats. Baked oatmeal makes the perfect quick and easy dessert for breakfast recipe!

What Makes This Lemon Blueberry Baked Oatmeal Healthy?

This lemon blueberry baked oatmeal recipe is special, because it is super healthy. For me the ingredients that go into a recipe are one of the most important factors – especially when it comes to breakfast.

I have a giant sweet tooth, so I am always craving a sweet breakfast recipe. However I don’t want all the processed sugars and oils typically found in sweet breakfast recipes. This blueberry lemon baked oatmeal is free of all the bad stuff and filled with nutrient dense ingredients instead. This baked oats recipe is:


How To Make Single Serve Baked Oats:

I live alone, so I am a sucker for a good single serve recipe. I personally prefer single serve breakfast recipes, because I find that even if you are living in a full house, people are picky about breakfast. Therefore single serve recipes like this lemon blueberry oatmeal bake are perfect, because everyone can find something they like.

However making single serve recipes can be a bit tricky. It’s always hard to gage the proper proportions when you’re changing the measurements of an existing recipe. For example who can measure out 4/5 a cup of oat flour.

Luckily this lemon blueberry baked oatmeal recipe is right in the middle and can easily be made for a crowd, or single serve. The recipe is made for 2, but can easily be halved, or doubled to suit your needs.

How To Naturally Sweeten This Lemon Blueberry Oatmeal Bake:

This lemon blueberry oatmeal bake is the perfect healthy plant based breakfast, because it is made with whole foods plant based ingredients. For me it is super important that the first meal of the day is made up of really wholesome ingredients.

Growing up my breakfasts looks like a very standard American breakfast. Super processed cereals, greek yogurt loaded with sugar, or oatmeal that was full of sugar. Luckily this lemon blueberry baked oatmeal recipe is free of all refined sugars.

I used date sugar for these oats. Date sugar is one of my favorite go-to natural sweeteners, because it is super natural. It is made from dates! Unlike many other sweeteners out there it does not undergo lots of processing. Date sugar is simply just ground up dates.

Therefore all the fiber and nutrients stay in tact. This is great for breakfast recipes, because it won’t leave you feeling sluggish at all. Since date sugar also contains fiber, it will keep you full for much longer.

Why I Love This Blueberry Lemon Baked Oatmeal:

Lemon flavored desserts have to be one of my all-time favorite flavors. I especially love the sweet and tart combination of lemon and blueberry together. Needless to say I am obsessed with these lemon blueberry baked oats.

However my love for this lemon blueberry oatmeal bake goes beyond the flavor, or the healthiness. I love these blueberry lemon baked oats, because they are easy to make, can be prepped, and because it is super affordable!

Making this lemon blueberry baked oatmeal is as simple as combining the ingredients and baking for about 25 minutes. If you’re like me and you love quick breakfast recipes this may not be appealing to you. However this leads me to the second reason I love these oats: they can be prepped.

This lemon blueberry oatmeal bake can be made ahead of time and be prepped and ready to go. Prepping these baked oats is as simple as baking them and covering in the fridge. If you plan to store these oats in the fridge for more than one day, I would suggest making them in a large dish.

I would suggest making a much larger batch, baking in a 8×8 dish, and cutting into squares. I would then recommend placing in an air tight container. This will help the oatmeal to be moist and fresh!

Lastly, these lemon blueberry baked oats are very affordable to make. The only ingredient that is a bit pricy is the date sugar. However the date sugar is key to making this recipe healthy. Since this recipe does not require a lot of date sugar, it works out to not be expensive if you already have date sugar on hand.

I use date sugar all the time. I definitely recommend investing in some. It is so versatile!

Frequently Asked Questions:

How Long Does Baked Oatmeal Last?

You may think of baked oatmeal as one of those foods that can’t be meal prepped. However this Blueberry Lemon Baked Oatmeal recipe is actually perfect for healthy breakfast meal prep. If stored properly this baked oatmeal can last a whole week in the fridge.

To store these lemon blueberry baked oats properly, you need an air tight container and an 8×8 pan. If you’re planning to store this recipe I assume you want to make more than 2 servings. I would suggest tripling this recipe to make 6 servings. You can bake this in a 8×8 dish. You will need to bake the oatmeal slightly longer as well, I would suggest 40 minutes.

Once cooked, remove from the oven and allow to cool before cutting. Cut into squares and place in air tight containers. It’s that simple! These baked oats will be more like slices of dessert bread, but that sounds good to me!

Are Baked Oats Actually Healthy?

Typically, baked oats are made with eggs, sugar, oil, etc. However if you make any of my baked oatmeal recipes you can be assured that they are super healthy. None of my recipes contain refined sugar, and I never bake with oil (or eggs obviously).

When you avoid these unhealthy ingredients and replace them with whole foods plant based ingredients you are left with a much healthier and nutrient dense baked oatmeal.

These lemon blueberry baked oats are special as well, because they contain antioxidants from the blueberries and vitamin C from the lemon!

Why Are My Baked Oats Soggy?

Baked oats blew up thanks to Tiktok. However I see way too many soggy baked oats recipes. For me, a proper baked oatmeal recipe is one where the oats are fluffy and cake like. This lemon blueberry baked oatmeal recipe is exactly that.

The key to making fluffy baked oatmeal is actually cooking it for the right amount of time. You can honestly eyeball how much liquid you put in the batter. However you need to make sure that you bake it long enough.

You’ll know when the oats are done by patting them with you hand on top. If you can easily make an impression with your hand, then they are not done. However if you pat them and they feel slightly springy, then they are perfect!

Can I Make Baked Oats In The Air Fryer?

One of my favorite life hacks is making baked oats in the air fryer. I have a very small kitchen, so I am all about small space cooking gadgets like an air-fryer. You can make these lemon blueberry baked oats in an air-fryer easily.

To make this recipe in the air-fryer, all you need to do is make it as you would, and place in small oven friendly baking dishes. Since an air fryer heats up faster, you will not need to bake these oats for as long. I usually set mine for about 18 minutes. It’s that simple!
