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.

Ingredients

Instructions

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!

Notes

    1. Don’t have bananas? You can sub the banana with ½ Cup of your favorite yogurt or 1 Cup Unsweetened Apple Sauce. Adjust the amount of honey/maple syrup to taste if needed.
    2. Any plant based protein powder works! If your protein powder is already sweetened, you may want to adjust the amount of honey to little or none at all (depending on how sweet you enjoy your foods). I DON'T recommend using whey protein powder because it can cause a chewy, almost crispy texture. I've had people use whey that love it still, but personally, I would avoid whey for these texture reasons.
    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.

    This sounds divine. I don’t use protein powders but used hemp seeds, also did use unsweetened soymilk (?this was 38 gm protein for the recipe). I choose soymilk as it has 9 gm protein per cup vs 1 gm in almond milk or 3 gm in oatmilk) my portion is larger as I usually eat 1/2 c oats for breakfast. Tons of protein options. Thanks again for this treat for breakfast. Oats have 5 gm protein per 1/2 cup. So I am swimming in at least 13 gm now excluding other add ins. Yeah!!!

    • Claire

      Laura, can’t wait for you to try it! Sounds like you will make it even more protein packed and I love that. Soy milk is a great option. That’s what i love about these baked oatmeal recipes, they’re so versatile. Let me know how it turns out when you use something other than protein powder because I have not tried that yet. Thank you again for your comment 🙂

    This is my new favorite summer/spring breakfast! Your lemon oatmeal bake with strawberries on top is AMAZING!

    For my recipe, I used steel cut oats in the same amount listed in the recipe. I only have vanilla plant protein powder so I used that in the same amount listed. I tripled the lemon zest (used 3 tbsp) because I LOVE lemon flavor, to compensate for the vanilla protein powder flavor and dense steel cut oats, and because my zest was previously frozen then thawed in my fridge (wasn’t sure how strong the zest would taste). I used the same amounts of lemon juice maple syrup listed. Next time, I might not add any maple syrup because my protein powder has stevia in it, so the end product was a bit too sweet for my taste.

    Overall, if I have lemons on hand, forget cookies, cakes and drinks! I’m making this oatmeal bake! It even tastes like it’s own dessert!

    Thanks for the recipe!

    • Claire

      Megan, that is awesome! I am so glad this is your new favorite! Love how you made it your own and added even more lemon! So yummy! And yes, sweetened protein powder definitely can replace the maple syrup or honey. Thank you so much for sharing and reviewing! Also, I am so impressed it worked with steel cut oats! I tried doing baked steel cut oats once and it DID NOT work for me haha. You’ll have to tell me your secret 🙂

  • Amy

    Super yummy!! One of my favorite baked oatmeal recipes!

    • Claire

      Amy! I am so glad you love this baked oatmeal flavor! Lemon is just the most refreshing flavor! Thank you so much for leaving such a nice comment 🙂 Happy Oatmeal Bakin’!

    This!!! I was skeptical at first; I love SHH baked oatmeal but I’m not a huge citrus person. Tried this topped with coconut mylk and blueberries and it is SO good! A light but filling breakfast I enjoyed. I usually use the Trader Joe’s protein powder, and it works great in this, but I tried brown rice protein powder once and it was good too (just less sweet).

    • Claire

      Yay!!! So glad you loved it even though you’re not a big citrus person. How fun is that! I also love how you’ve tried it with different protein powders 🙂
