Easy and delicious blueberry zucchini muffins, with a touch of lemon zest. A great morning muffin that can be made with fresh or frozen blueberries.

Zucchini makes a great addition to muffins, ensuring they are always moist and flavourful. These blueberry zucchini muffins have a bit of lemon zest added, for a bright flavour and a perfect combination with the plump blueberries.

These muffins are made without butter, sour cream or yogurt, so I never have to worry if I have all the ingredients on hand. These simple pantry muffins are also a great use for extra zucchini!

Ingredients and Substitutions

Zucchini – shred the zucchini with a box grater. No need to peel. Don’t squeeze or drain the zucchini before using.

Blueberries – you can use either fresh or frozen blueberries. If using frozen blueberries, no need to thaw. Use from frozen. Allow a few extra minutes of baking time for frozen blueberries.

Lemon Zest – I love the bright flavour lemon zest brings to these muffins, but it is completely optional and you can omit if you prefer or don’t have lemons on hand.

Step-by-Step Photos

  1. Mix together the wet ingredients and shredded zucchini.
  2. Whisk together the dry ingredients.
  3. Add the wet ingredients to the dry ingredients.
  4. Stir just until barely combined.
  5. Add the fresh or frozen blueberries to the batter. (Note: I made a 1/2X batch recipe here, which made 8 muffins. The 1X recipe will make about 16 muffins).

Recipe Tips

  • You don’t need to line the muffin cups with paper liners, but you can if you like.
  • If making a 1/2X batch of muffins (to make 8 muffins), you will end up with a 1/2 egg measurement. To get 1/2 egg, break an egg into a small cup, stir together and use 1/2 of it.
  • Be sure not to over-mix the batter after mixing together the wet and dry ingredients. Mix just until combined and no flour is visible.
  • The muffins are tender when hot, so be sure to let them sit in the muffin tin for 5-10 minutes before transferring to a cooling rack to cool completely.


Swap the lemon zest for orange zest or lime zest, for more great flavour combinations!
