Ingredients

Ingredients for making gluten-free vegan apple baked oatmeal.

Ingredient Notes

  • Apples – Choose crisp varieties like Honeycrisp or Granny Smith to keep pieces from turning mushy when baked. Gala or Pink Lady also work well.
  • Brown sugar – If you follow a vegan diet, verify the sugar is processed without bone char or substitute coconut sugar.
  • Oats – To ensure gluten-free results, use certified gluten-free or purity protocol oats. Rolled oats are best; avoid instant oats for this bake.
  • Applesauce – Unsweetened applesauce keeps the oatmeal moist and acts as an egg replacement in this vegan version.
  • Milk – Unsweetened almond milk keeps the bake dairy-free, but any unsweetened non-dairy milk (oat, soy, cashew, coconut) or regular cow’s milk can be used if preferred.

Tip: Select crisp apple varieties for baked dishes. They hold their shape and add pleasant texture; softer apples may break down during baking.

Expert tips

  • Leave apple skins on to save time and add texture, or peel if you prefer a softer bite.
  • Choose certified gluten-free oats (purity protocol) if you need a gluten-free recipe; conventional oats may be cross-contaminated.
  • Most milks work in this recipe: dairy, almond, oat, or coconut. Unsweetened versions are best so the added sugar can be controlled.
