    Why you'll love this recipe

    Secret Veggies. This zucchini bread oats recipe is a sneaky way to incorporate vegetables into your breakfast.

    Packed with Protein. Starting your day with protein is essential for staying energized. This protein zucchini oats is a great source of protein keeping you fuller for longer.

    Tastes Like Dessert. This breakfast meal prep recipe delivers the warm, comforting flavours of zucchini bread in a healthy and satisfying breakfast option.

    Meal Prep Friendly. Baked Zucchini Oatmeal is fantastic for meal prep! Prepare on the weekend and store for grab-and-go breakfast options throughout the week.

    Ingredients

    Rolled oats. These are the heart of the baked oatmeal. You could blend them if you don't like the oat texture, or use quick oats for a different texture.

    Flour. A small amount of all-purpose flour adds a cakey zucchini bread touch. You could omit (just add more rolled oats) or use a different type of flour.

    Banana and egg. Helps bind the zucchini bread baked oats together.

    Chia seeds. Adds extra protein, fibre and healthy fats. Skip if you don't want them.

    Protein Powder. Totally optional but I like to add extra protein to ensure I meet my protein goals for the day. I recommend a neutral or vanilla flavour for the zucchini oats.

    Maple syrup and spices. Adds a touch of natural sweetness to the baked zucchini oats. The spices make it really taste like a zucchini bread for breakfast. Feel free to adjust depending on your preferences.

    Zucchini. The main element of the zucchini oatmeal bars. No need to remove the moisture as it helps provide a great texture in the final zucchini oat bake.

    Please check the recipe card for full list of ingredients and quantity. See below for substitutions and variations.

    How to make zucchini baked oats

    1. Prepare

      Coat the bottom of an oven-safe pan with a small amount of oil or butter. I use an almost square pan for mine (link below), but you can use an oval or rectangular, you might just have to adjust the cooking time (tips in main recipe below).

    2. Add ingredients

      Add all ingredients except for the zucchini, sultanas and nuts. Mix well. No need to remove excess liquid from the zucchini as this helps the oatmeal with zucchini texture when baked.
       
      Add zucchini and sultanas, gently mix and then flatten the top. Add nuts if desired.

    3. Bake

      Bake for approx. 40 minutes @160C or until the top is golden brown. You can bake for less time (approx. 30 minutes) if you like a more gooey texture, or longer (approx. 40 minutes) if you like it really cakey.

    4. Serve

      Top with extra sultanas and walnuts, maybe a bit of almond butter. You could also add yoghurt, fresh fruit and cinnamon sugar as a couple of extra ideas for this breakfast meal prep.

    Top Tip

    Don't stress too much if you have more zucchini or less zucchini. I've done this with up to 2 cups of zucchini and as little as ½ cup and it's still worked out well. They're very subtle in flavour and don't have huge amounts of liquid which would impact the zoats.

    Substitutions and variations

    Sweetener. I used maple syrup in this recipe, but you could also substitute with another liquid sweetener such as honey, agave nectar. Adding a dried sweetener will be fine, but the texture of the zucchini baked oats will differ slightly.

    Milk. Substitute for any type of milk - Cow's or non-dairy.

    Protein powder. I recommend a neutral protein flavour such as vanilla or plain. If you want to omit, add the same amount of flour or oats.

    No Banana. Substitute with ¼ - ½ cup applesauce or yoghurt if you don't have a banana.

    Notes

    Note 1 - Banana
    You can substitute with approx. ½ cup applesauce or yoghurt, or another egg. 
    Note 2 - Egg
    For an egg-free option, use a flaxseed egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water and let sit for 10 minutes). Or replace with another banana. 
    Note 3 - Protein Powder
    I recommend a neutral or vanilla flavour. If not using, substitute with equal amounts flour.
    Note 4 - Milk
    Use milk of your preference. Nutrition information based off cows milk.
    Note 5 - Cooking Time
    Cooking time based on a Square medium casserole approx. 24x24cm. If using a larger one, decrease the amount of time. If using a smaller one, increase the amount of time. This will also vary depending on how "cakey" or "gooey" you want the baked oats. 30 minutes using the above casserole will make it really gooey, 50 minutes will make it more cakey. I like mine in between which is why I state 40 minutes if you like the texture in the pictures.
    Serve with
    Serve with a side of Greek yogurt and fresh berries. If looking for additional fibre and protein, add some homemade chia jam.
    Storing
    Allow to cool completely (no more than 2 hours at room temperature) then store in an airtight container for up to 5 days. 
    Reheating 
    You can eat this cold. If reheating, add individual pieces to the microwave and reheat for 30-60 seconds until warmed through. 
    Freezing
    Wrap individual portions in aluminium foil, plastic wrap or baking paper and store in the freezer for up to 3-6 months. See post for more freezing baked oats information.
