Summer harvests always leave me with an abundance of zucchini and blueberries, and this blueberry zucchini bread with lemon glaze has become my favorite way to bring them together. It is tender, moist, and packed with bright flavors that feel both comforting and refreshing. Whether for breakfast, an afternoon treat, or a gift for friends, this bread never disappoints.
I first baked this bread to use up a pile of zucchini from my garden and a basket of blueberries from the market. Now it is a seasonal tradition my family looks forward to every summer.

One of my favorite parts of this recipe is how the lemon glaze ties everything together. It reminds me of summer mornings when I shared warm slices with my grandmother who loved adding extra zest to the glaze for even more brightness.
Storage Tips
Wrap the bread tightly in plastic wrap or store in an airtight container at room temperature for up to 3 days. Refrigerate during warm months to keep the glaze firm. For longer storage freeze unglazed bread up to 3 months and glaze after thawing.
Ingredient Substitutions
