Lemon Blueberry Oatmeal Bake

This lemon blueberry oatmeal bake is light and cake-like, and the perfectly healthy breakfast or have as an afternoon snack. It's loaded with juicy blueberries and fresh lemon zest and juice, giving it the ultimate blueberry lemon flavor. I love pairing it with Greek yogurt to add some protein and sprinkling additional blueberries on top or fresh berries on the side to make it a balanced meal or snack!

Some of my other favorite breakfast recipes include carrot cake oatmeal bars, pumpkin baked oats with a coffee yogurt sauce, cinnamon granola with pecans, and banana nut protein muffins!

If lemon and blueberry are one of your favorite combinations, you definitely need to add this baked oatmeal recipe to your breakfast rotation. It's one of the best breakfast meal preps because you can easily separate out individual portions to make for a quick breakfast. You can even make a double batch and freeze for another time!

Equipment

• 8x8" baking dish - this is what you'll bake the oatmeal in. It's the ideal size to get 9 pieces!
• Small bowl - you want a small bowl to mix the dry ingredients in separately from the wet.
• Large bowl - a 3- or 5-quart bowl is ideal for mixing the wet ingredients in because you'll then add the dry ingredients and fold in the blueberries. So you want enough space!
• Whisk - this is ideal for mixing the dry ingredients as well as wet.
• Rubber spatula - I love using a rubber spatula to fold in the blueberries to the batter. This will prevent most of the blueberries from bursting!
• Parchment paper - lining the baking dish with parchment paper will prevent the lemon blueberry baked oatmeal from sticking to the pan. This parchment paper is great because it comes pre-cut and fits into this 8x8" baking dish perfectly if you cut it in half!

Ingredients

Full ingredients, measurements, and instructions can be found in the recipe card at the bottom of this post.

• Old-fashioned oats (or rolled oats) - these are a staple ingredient in this recipe! They're a good source of fiber as well as B vitamins. Since they're a complex carbohydrate, this lemon blueberry oatmeal bake will keep us full all morning long. Especially if you pair it with a high quality protein like Greek yogurt! Please note that steel cut oats or instant quick oats will not bake the same and yield a different texture. If you are gluten-free, be sure to look for certified gluten-free oats.
• Milk - any milk will work to add liquid to the recipe for the oats to soak up. You can use cow's milk, unsweetened almond milk, soy milk, oat milk, or any non-dairy milk of choice!
• Unsweetened applesauce - applesauce adds moisture to baked goods without a lot of the fat and calories that can come from oils and butter. Plus it adds a hint of natural sweetness!
• Pure maple syrup - I'm a big fan of using pure maple syrup as a natural sweetener in baking. While still an "added sugar," it's a lot less processed than granulated white sugar or brown sugar. Be sure to look for a maple syrup that just has "maple syrup" listed under the ingredients!
• Fresh lemon juice - to get the ultimate lemon flavor, I high recommend using fresh lemon juice in this recipe!
• Fresh lemon zest - lemon zest adds even more lemon flavor! Be sure to zest only the yellow part of the lemon. Once you get into the white rind, it can become bitter.
• Olive oil - oils like olive oil are a good source of unsaturated fat (LINK) and a healthier alternative to butter and coconut oil. I recommend using classic olive oil and not extra virgin.
• Eggs - eggs help to bind the oatmeal bake as well as add some protein!
• Almond extract - almond extract adds such a beautiful subtle flavor to this oatmeal recipe. You can substitute pure vanilla extract if you'd like!
• Baking powder - this will allow the blueberry lemon baked oatmeal to rise and give it a cake-like texture. Be sure to check the expiration date for optimal results!
• Table salt - this balances out the sweetness of the this lemon baked oats recipe!
• Blueberries - blueberries are a good source of fiber and antioxidants like anthocyanins, which help to fight inflammation! They're a powerhouse when it comes to nutrient and compliment the tart lemon flavor so well.

How to Make Lemon Blueberry Baked Oatmeal

Variations & Substitutions

• I haven't tried this but this recipe would be good made into oatmeal cups! These would be perfect for an easy grab-and-go snack or breakfast.
• I would not substitute steel cut oats or instant quick oats in lieu of old-fashioned rolled oats, as they're different and will yield a different result!
• White chocolate chips would be a great addition to this delicious baked oatmeal recipe!

Pro Tips

• When zesting lemons (and citrus in general), be sure to zest only the yellow part of the lemon. Once you get into the white rind, it can become bitter.
• Store-bought lemon juice will work but I highly recommend juicing fresh lemons!

Serving

I love serving this lemon blueberry oatmeal bake with low-fat Greek yogurt for extra protein (and some probiotics). You can also serve with a sprinkle of chia seeds, drizzle of nut butter, and fresh fruit!

Storage

• Store this lemon bluberry baked oatmeal in an airtight container in the refrigerator for up to 5 days.
• This recipe freezes really well too! I recommend wrapping individual portions in plastic wrap and then putting in an airtight container before freezing. It should freeze for up to 2 months!
