Baked Oats With Blueberries And Lemon
Baked oatmeal recipes are something we’ve been making for years and are one of our favorite breakfast recipes to share. If you’ve never tried baked oatmeal, think of it as a bowl of oatmeal, but baked into a more sturdy form, like a soft bar. We love to serve pieces of an oatmeal bake in bowls along with a dollop of yogurt or nut butter, or a drizzle of maple syrup or honey and some fresh fruit on top.
Highlights: Blueberry Lemon Baked Oatmeal
A few reasons we know you’ll love this baked oatmeal recipe:
- The combination of lemon and blueberries, along with the optional white chocolate chips, is a match made in flavor heaven
- It’s a lot like a mix between a lemon blueberry muffin and a bowl of delicious blueberry oatmeal
- This recipe doesn’t contain any egg, milk, yogurt, or butter (like many baked oatmeal recipes do), making it vegan and 100% plant based
- Get maximum nutrition out of your breakfast with healthful additions, such as flax seeds, chia seeds, rolled oats, applesauce, and blueberries
Ingredients To Make Blueberry Lemon Baked Oatmeal
Here are the ingredients (and substitutions) you’ll need to make this baked oats recipe:
- Flaxseed meal – if you don’t want vegan baked oats, you may use 1 large eggs instead, and omit the flaxseed meal and water
- Old-fashioned rolled oats – if gluten-free is needed, be sure to use certified gluten-free oats. For the best outcome, always use old-fashioned oats to make baked oatmeal, and not steel cut oats or quick oats, as they will not provide the best texture
- Chia seeds
- Baking powder
- Maple syrup – we prefer maple syrup, but you may use honey, if vegan oats are not needed
- Lemon – you’ll use both the zest and juice of a fresh lemon
- Unsweetened applesauce
- Non-dairy milk of choice – to keep this recipe dairy-free, use any favorite non-dairy milk such as unsweetened almond milk or oat milk; however if plant-based is not needed, you can substitute any preferred dairy milk
- Avocado oil – may substitute melted butter, olive oil, or coconut oil
- Blueberries – you can use frozen or fresh blueberries, or use another type of fresh berries or swap in frozen wild blueberries for extra nutrition and great taste
- White chocolate chips – these are optional, but they make a yummy addition
