The only thing I need to say before you dive into the recipe is: BAKED OATMEAL IS EVERYTHING! I make baked oatmeal almost every Sunday as a part of my meal prep to prepare for the week. It is such a timesaver because I can toss all of the ingredients in a casserole dish, bake for about 45 minutes, and it’s finished! Now I have breakfast ready for throughout the week. I can easily rewarm a portion of the baked oats and enjoy breakfast without taking too much time wondering what I will eat or preparing a cumbersome meal!

This recipe is a spin-off of my popular Apple Cinnamon Baked Oats. The only difference is instead of using sliced apples, we are using blueberries in this recipe.

Ingredients You’ll Need To Make This Healthy Blueberry Baked Oatmeal Recipe

  • Rolled Oats: If you are gluten intolerant, be sure to use gluten-free oats.
  • Frozen or Fresh Blueberries: Use whichever you have on hand. I tend to use frozen organic blueberries for this recipe.
  • Ground Flaxseed: The flax seeds add extra protein and omega 3s, and helps to bind the ingredients! I like to use Viva Natural Flax Seeds | Amazon
  • Applesauce: The applesauce also helps to bind the ingredients and provides a subtle sweetness to the baked oatmeal.
  • Non-Dairy Milk: I prefer use unsweetened almond milk. You can use whichever non-dairy milk you prefer. If you’re up for it, you can make your own oat milk in 5 minutes using my Homemade Oat Milk Recipe!
  • Maple Syrup: The maple syrup provides the perfect amount of sweetness. You can also use honey or coconut sugar.
  • Seasonings and such: Cinnamon, vanilla extract, baking powder, sea salt
  • Nuts -This is optional. I like to add pecans, but you can also add sunflower seeds, pumpkin seeds, sliced almond, or keep it nut-free!
