One square of this healthy Lemon Baked Oatmeal is only 133 calories and 2 grams of fat! It also gives you a whopping 6.9 grams of protein! Which means this breakfast will keep you full! Average baked oatmeal recipes have little to no protein content.

I absolutely love how it’s sweetened with banana and maple syrup. AND that you only need the baking dish to make it. No extra dishes! This will be your new go to for healthy meal prep breakfast recipes!

Gluten-free, Dairy-free, Vegan Baked Oatmeal!

Gluten-free: All of my baked oatmeal recipes are gluten-free! You would never guess it either, especially with my Chocolate Baked Oatmeal. This healthy lemon oatmeal recipe calls for gluten-free rolled oats. Bob’s Red Mill is a trusted gluten-free brand you can use!

Dairy-free: There’s also no dairy in this baked oatmeal! You can use any plant based milk. I use unsweetened almond milk.

Vegan: The protein powder we use is also plant based, making this the perfect vegan breakfast!

How to Make this Healthy Vegan Breakfast Recipe

Just like my Chocolate Chip Cookie Baked Oatmeal and Chunky Monkey Baked Oatmeal recipes, we only use the baking dish to whip this healthy, delicious breakfast up!

Here are the steps:

  1. Get out a 2-quart baking dish (here is the exact one I use).
  1. Using the back of a fork, mash the ripe bananas right in the baking dish.
  1. Add in all other ingredients and stir it up!
  1. Pop it in the oven at 350 F. for 40 minutes and serve with fresh bananas, berries, peanut butter and plant based milk!

You can take a peek at my other baked oatmeal recipe to see a quick video of these steps. I also have videos on Instagram of me making this baked oatmeal!

Easily Make this a Blueberry Lemon Baked Oatmeal!

You can easily make this baked oatmeal into a lemon blueberry flavor by adding about ½ Cup of fresh or frozen blueberries! If you leave the blueberries out, it will taste more like a lemon bar.

Prep Time 5 minutes
Cook Time 40 minutes
Total Time 45 minutes



1. Preheat the oven to 350 F.

2. In a 2 quart baking pan mash the banana with the back of a fork. Add all other ingredients into baking dish and stir until mixture is combined.

3. Place in the oven to bake at 350 F. for 35-40 minutes until golden brown.

4. Let cool for a few minutes or until set and serve with fresh berries, banana slices, nut butter, or your favorite milk! 

5. Store in the fridge for up to a week and enjoy a premade healthy breakfast all week long!


  1. Don’t have bananas? You can sub the banana with ½ Cup of your favorite yogurt. You will need to adjust the amount of honey used depending on how sweet or tart your yogurt is.
  2. Any protein powder works! If your protein powder is sweetened, adjust the amount of honey to your taste. 2 scoops of collagen also works!
  3. You can use any liquid of choice for this recipe. You can swap the milk for all water or do a combination that totals 2 cups.
  4. Most oats are gluten-free, just make sure by checking the packaging! I love this brand.
