Ingredient Notes

Turning zucchini into amazing lemon muffins is easy with a few simple ingredients.

  • Shredded zucchini – You can use freshly shredded zucchini or thawed frozen zucchini in these muffins.
  • Butter – Using melted butter results in a moist muffin with a delicate crumb.
  • Milk – I use skim milk. Whole milk or even nondairy milk will work too.
  • Lemons – These muffins use both the juice and zest in the batter. Get our tips on how to zest a lemon.
  • Lemon extract – The super concentrated lemon flavor gives the muffins an even more intense zesty taste.
  • Poppy seeds – The tiny black seeds lend a mild nutty flavor to the lemon muffins.

Easy Instructions

Lemon Zucchini Muffins are a breeze to make.

  1. Make the batter: Mix together the dry ingredients. Then mix in the zucchini and wet ingredients until combined. Fold in the poppy seeds last.
  2. Fill muffin tins: Divide the batter evenly into a greased muffin pan.
  3. Make the crumb topping: Use a fork to combine additional flour with melted butter and sugar. Sprinkle it over the tops of the unbaked muffins.
  4. For the lemon glaze: Combine the glaze ingredients in a small bowl. Drizzle it over the baked muffins before serving.

Tips and Tricks

  • Grate the zucchini with a box grater or other hand held grating tool. You want it finely shredded; not pureed.
  • Fill each cavity of the muffin tin about 2/3 of the way full. This leaves them room to rise while getting a slightly domed top.
  • Bake the muffins until lightly browned. They’re done baking when a toothpick inserted in the center comes out clean.
  • Let the muffins cool completely before adding the glaze. If the muffins are warm the glaze will melt and make a sticky (but still delicious) mess.
  • Store baked muffins in an airtight container at room temperature.

Recipe FAQs

What can I use in lemon muffins instead of poppy seeds?

Chia seeds can be used in place of the poppy seed muffins. They have a similar appearance and taste.
You can also simply omit the seeds altogether. The Lemon Zucchini Muffins are delicious even without poppy seeds.

Can I freeze these? With or without the glaze?

Yes, these muffins are perfect for freezing! After baking, transfer them to freezer bags and keep frozen for up to several months.

I recommend storing most muffins without glaze. It only takes a minute to whip up fresh glaze to drizzle over the muffins after they’ve thawed.

Do I have to squeeze out the water from the zucchini?

Squeezing out the water isn’t usually necessary. The natural liquid in shredded zucchini makes the muffins so moist!

I do find that zucchini that’s been frozen and thawed tends to be much more watery than freshly grated. If you use frozen zucchini in this recipe, I recommend giving it a squeeze in a strainer over the sink to remove the excess liquid.
