Tips for the Best Lemon Zucchini Muffins:
Don’t Over-Squeeze the Zucchini
Zucchini adds moisture, which keeps these muffins soft and tender. Lightly squeeze out excess liquid, but don’t wring it completely dry.
Use Fresh Lemon
Fresh lemon juice and zest give the muffins their bright citrus flavor. Bottled lemon juice won’t taste as fresh.
Don’t Overmix
Stir the batter just until combined. Overmixing can make muffins dense instead of soft and fluffy.
Let Muffins Cool Before Glazing
If the muffins are too warm, the glaze will melt right into them. For a pretty drizzle, wait until they are mostly cooled.
Chop Thyme Finely
Fresh thyme adds a lovely herbal note, but a little goes a long way. Finely chop it so the flavor is evenly distributed.
Easy Variations
Make Them Extra Lemon-y
Add more lemon zest to the batter or use lemon extract for a stronger citrus flavor.
Add Blueberries
Fold in ½ cup fresh or frozen blueberries for a lemon blueberry zucchini muffin.
Make Them Dairy-Free
Use dairy-free yogurt and plant-based milk.
Add Crunch
Sprinkle sliced almonds or coarse sugar on top before baking.
Skip the Glaze
For a lower-sugar muffin, skip the glaze and serve them plain or with a light spread of butter.
What to Serve with Lemon Zucchini Muffins
These muffins are delicious with:
- Greek yogurt
- scrambled eggs
- fresh fruit
- smoothies
- tea or coffee
- brunch boards
They’re also great for lunchboxes, after-school snacks, or make-ahead breakfasts.
Storage and Freezing
Store muffins in an airtight container at room temperature for up to 2 days or in the refrigerator for up to 5 days.
To freeze, skip the glaze and freeze muffins in a freezer-safe bag for up to 3 months. Thaw at room temperature, then drizzle with glaze before serving if desired.

Healthy Zucchini Lemon Muffins
Ingredients
- 1 cup shredded zucchini lightly squeezed of excess moisture
- 1 cup all-purpose flour
- 3/4 cup whole wheat flour or whole wheat pastry flour or additional all-purpose flour
- 1 tsp baking powder
- 1/2 tsp baking soda
- 1/2 tsp kosher salt
- 1 tbsp fresh lemon zest
- 1 tsp fresh thyme leaves finely chopped
- 2 large eggs
- 1/2 cup Greek yogurt
- 1/3 cup olive oil or avocado oil
- 1/3 cup honey or maple syrup
- 1/4 cup milk
- 2 tbsp fresh lemon juice
- 1 tsp 1 teaspoon vanilla extract
- 2 tbsp coarse sugar optional, for topping
Lemon Glaze
- 1/2 cup powdered sugar
- 1-2 tbsp fresh lemon juice
- 1/2 tsp lemon zest plus more for topping
Instructions
- Preheat oven to 350°F. Line a 12-cup muffin tin with paper liners or lightly grease with nonstick spray.
- Shred zucchini using a box grater. Lightly squeeze out excess moisture with a clean kitchen towel or paper towels. You don’t need to remove all the moisture—just enough so the muffins don’t become soggy.
- In a large bowl, whisk together flour, whole wheat flour, baking powder, baking soda, salt, lemon zest, and fresh thyme.
- In a separate bowl, whisk together eggs, Greek yogurt, oil, honey or maple syrup, milk, lemon juice, and vanilla extract until smooth.
- Pour the wet ingredients into the dry ingredients and gently stir until just combined. Fold in the shredded zucchini. Be careful not to overmix.
- Divide the batter evenly among the muffin cups, filling each about ¾ full. Sprinkle with coarse sugar if desired.
- Bake for 18–22 minutes, or until the tops spring back lightly and a toothpick inserted into the center comes out clean. Let muffins cool in the pan for 5 minutes, then transfer to a wire rack.
- In a small bowl, whisk together powdered sugar, lemon juice, and lemon zest until smooth. Add more lemon juice for a thinner glaze or more powdered sugar for a thicker drizzle.
- Drizzle glaze over cooled muffins and top with extra lemon zest. Let the glaze set slightly before serving.
