  • Berries – This recipe uses either fresh or frozen strawberries. They can also be replaced with other berries, or a mix of berries of choice. A good option is raspberries or blackberries, also check out this Blueberry banana baked oatmeal. 
  • Sweetener – instead of maple syrup, other liquid sweetener like agave syrup or brown sugar can also be used. If you like a sweeter dish, add more sweetener to taste, or top the baked oatmeal with a drizzle of maple syrup.

Variations

  • Protein – For added protein, mix in 2 tablespoons of your favourite protein powder into the oatmeal. Some great flavours to use are vanilla or berry flavor.
  • Gluten-free – Although oats are naturally gluten-free, they may contain traces of gluten. To ensure that these baked oats are gluten-free, use only certified gluten-free oats. They can usually be found in the glute-free section of the grocery store.
  • Sweetener – This baked oatmeal is not overly sweet. Most of the sweetness comes from the very ripe bananas and just a little added maple syrup. If the rhubarb is very tart, add more sweetener to taste, or top the baked oatmeal with a drizzle of maple syrup. 
  • Vegan – for a vegan baked oatmeal recipe, use a plant based milk like almond milk, soy milk or oat milk. If topping with yoghurt, use a plant based kind.
  • Nuts – add some crunchy nots like walnuts, almonds or pecans. For an allergy friendly oatmeal, use sunflower or pumpkin seeds.
