Make this easy gluten-free orange zucchini bread with orange glaze for a sweet, nutritious bread perfect for breakfast or snacks!


Units Scale
  • 1 cup grated zucchini (see notes)
  • 3 cups (335-340 grams) blanched almond flour
  • 1/4 cup (30-35 grams) gluten-free oat flour (see notes for substitute)
  • 1 Tablespoon ground flaxseed
  • 1 1/2 teaspoons baking powder
  • 1 teaspoon baking soda
  • 1/4 teaspoon kosher salt
  • 3 large eggs, room temperature
  • 1 teaspoon vanilla
  • 1/2 cup maple syrup or agave
  • 1/3 cup orange juice + 1 Tablespoon orange zest
  • Optional: orange extract
  • Optional Garnish: orange slices to top

Optional Orange Glaze (enhances orange flavor)

  • 1 1/3 cup powdered sugar (or sugar-free alternative)
  • 1/4 cup orange juice
  • 2 Tablespoons melted butter or refined coconut oil
  • Optional: 1/4 teaspoon ground ginger
  • Dash orange zest or orange peel


Optional Glaze


Substitutes –  2 to 3 Tablespoons coconut flour (equivalent grams) may be substituted for oat flour, but note the inside texture and baking time will vary.

Zucchini Tips – Do not grate zucchini too finely. Some moisture/water is okay to leave from the grated zucchini. There is no need to squeeze any water out of the zucchini.

Baking Tips – An 8×4 pan will create a taller loaf but the center will take longer to bake. Use foil to cover if the top is starting to brown. Metal loaf pans bake bread the quickest in comparison to glass pans or ceramic. I prefer to use metal pans for baking bread.
