This Blueberry Baked Oatmeal Recipe bakes oats, fresh or frozen blueberries, and milk together to give you a comforting and hearty breakfast or brunch. Vegan, Gluten-Free and Nut-Free Options.
Dry Ingredients: Add the rolled oats, quick oats, flax seed, cinnamon, cardamom, baking powder, and salt to a 9x13” baking dish and mix well.
Wet Ingredients: Add the milk, maple syrup, lemon juice, vanilla, and thawed blueberries and mix again. Top the oatmeal with additional fresh blueberries, if desired.
Bake: Bake for 30 to 35 minutes, until the top of the oatmeal is golden (Note: if you want to serve a runnier oatmeal, bake for only 20 to 25 minutes).
Serve & Store: Serve immediately for a softer oatmeal, or let the oatmeal cool in the baking dish, then slice and serve into bars. Serve as-is or with a drizzle of nut butter and/or milk. Store leftovers in the refrigerator for up to 5 days, or pre-portion the oatmeal and store in the freezer for up to 2 months.
Notes
Gluten-Free: Use gluten-free oats to make this recipe gluten-free.
Fresh vs Frozen Blueberries: This recipe tastes delicious with both fresh and frozen blueberries - frozen berries are usually more cost effective, so I tend to use those. If using frozen berries let them fully thaw in the bag and do not drain the liquid.
Maple Syrup: Swap the maple syrup for equal parts cane sugar, agave, or brown sugar. This recipe is not very sweet as-is, but feel free to add more or less sweetener to your personal preference.
Walnuts: Swap the walnuts for pecans, almonds, or pumpkin seeds for a nut-free option!
Protein Powder: Add 1-2 scoops of vanilla protein powder to this recipe for a protein boost! If doing this, increase the liquid to 3 cups and omit the sweetener.
