Homemade Lemon Yellow Squash Bread

If you ask me, quick breads are one of the best ways to use up summer squash.

This lemon yellow squash bread is a treat that combines tender shredded squash with bright citrus flavors. The grated squash keeps the bread moist while fresh lemon zest and candied lemon pieces add a nice zing in every bite.

It’s mixed together like a classic quick bread, with butter and sugar creamed until fluffy before adding eggs and yogurt. A simple glaze made with lemon juice and confectioners sugar gets drizzled on top once it’s cooled.

It’s the kind of recipe that works great for breakfast or an afternoon snack with coffee.

What Kind of Summer Squash Should I Use?

Yellow squash is the classic choice for this recipe, but you can honestly use any summer squash you have on hand. Zucchini works just as well and you probably won’t even notice a difference in taste, though it will give your bread a slightly greenish tint instead of that sunny yellow color. If you’re picking squash from the store or your garden, go for medium-sized ones rather than those giant ones – the smaller squash tend to have fewer seeds and a better texture. Make sure to squeeze out as much moisture as possible after grating, or your bread might end up too dense and wet.

Options for Substitutions

This recipe is pretty forgiving when it comes to swaps, so here are some options if you need them:

• Summer squash: Yellow squash and zucchini are basically interchangeable here. Both have similar moisture content and mild flavor, so use whichever you have on hand. Just make sure to squeeze out the excess water either way.
• Butter: You can replace the butter with an equal amount of vegetable oil or melted coconut oil. The texture will be slightly different but still moist and tasty.
• Greek yogurt: Regular yogurt, sour cream, or even mashed banana (about 1/2 cup) will work in place of Greek yogurt. Each brings a slightly different flavor, but all keep the bread nice and moist.
• Milk: Any milk works here – dairy, almond, oat, or soy. They’re all fine for this recipe.
• Fresh lemon: In a pinch, you can use bottled lemon juice (about 3 tablespoons total) and 1 tablespoon of lemon extract for the zest, though fresh lemon definitely gives better flavor.
• Candied lemon peel: This is totally optional anyway, but if you want to include it and don’t have any, try adding an extra teaspoon of lemon zest or some poppy seeds for texture instead.

Watch Out for These Mistakes While Baking

The biggest mistake you can make with this bread is skipping the step of squeezing out excess water from the grated squash, which will leave you with a dense, gummy loaf instead of a light and tender one – use a clean kitchen towel or cheesecloth and really wring it out until no more liquid comes out.

Another common error is overbaking, so start checking your bread at the 50-minute mark by inserting a toothpick into the center, and remember that it should come out with just a few moist crumbs, not completely clean like a cake.

Don’t glaze the bread while it’s still warm, as the heat will cause the glaze to run right off instead of setting into that perfect sweet coating – let it cool completely first, and if you want an extra glossy finish, apply two thin layers instead of one thick one.

What to Serve With Lemon Squash Bread?

This bread is perfect for breakfast or an afternoon snack with a hot cup of coffee or tea. I love slicing it up and serving it with a smear of cream cheese or butter, which balances out the bright lemon flavor. It also makes a great addition to a brunch spread alongside fresh fruit, scrambled eggs, and bacon. If you want to get fancy, serve it with a dollop of whipped cream or Greek yogurt and some fresh berries on the side.

Storage Instructions

Store: This lemon squash bread stays moist and delicious when wrapped tightly in plastic wrap or stored in an airtight container at room temperature for up to 3 days. If you want it to last longer, keep it in the fridge for up to a week, though I find it tastes best at room temperature.

Freeze: You can freeze this bread for up to 3 months, either as a whole loaf or in individual slices. Wrap it well in plastic wrap, then again in foil or a freezer bag to prevent freezer burn. Slicing it before freezing makes it easy to grab just what you need for breakfast or a snack.

Thaw: Let frozen slices sit at room temperature for about 30 minutes, or thaw the whole loaf overnight on the counter. If you’re in a hurry, you can microwave individual slices for about 20-30 seconds on low power.

• Calories: 1950-2100

• Carbohydrates: 335-360 g

Ingredients

For the bread:

• 1 1/4 cups yellow squash (finely grated and squeezed dry to prevent sogginess)
• 1/2 cup butter (I like Kerrygold unsalted butter for this)
• 1 cup sugar
• 2 eggs (room temperature, about 70°F)
• 1/2 cup yogurt
• 1/2 cup milk
• 2 lemons (freshly zested for the brightest citrus aroma)
• 2 cups flour (I always use King Arthur all-purpose flour)
• 2 tsp baking powder
• 1/2 tsp salt
• 1/4 cup candied lemon zest (finely chopped, about 1/8-inch pieces)
• 1 tsp vanilla extract
• 1/4 tsp ground ginger

For the glaze:

• 1 1/2 tbsp lemon juice
• 1 tbsp honey (I prefer Nature Nate’s for its consistency)
• 1/2 cup confectioners sugar (sifted to remove lumps)

Step 1: Prepare the Squash and Mise en Place

• 1 1/4 cups yellow squash
• 1 loaf pan, greased

Preheat your oven to 350°F and grease a 9×5 inch loaf pan or similar size.

While the oven heats, finely grate the yellow squash using the small holes of a box grater or a microplane.

This is crucial—transfer the grated squash to a clean kitchen towel or cheesecloth and squeeze it firmly over the sink to remove as much moisture as possible; this prevents a soggy loaf.

I like to squeeze it multiple times to get every last drop of water out.

Measure out all remaining ingredients and set them aside—this organized prep (mise en place) makes the mixing process smooth and ensures you won’t miss anything.

Step 2: Cream Butter and Sugar, Then Build the Wet Base

• 1/2 cup butter
• 1 cup sugar
• 2 eggs
• 1/2 cup yogurt
• 1/2 cup milk
• 2 lemons
• 1 tsp vanilla extract
• 1 tbsp honey
• 1 1/2 tbsp lemon juice

In a large mixing bowl, cream together the softened butter and sugar using an electric mixer on medium speed for about 2-3 minutes until the mixture is light, fluffy, and pale—this incorporates air and creates a tender crumb.

Add the room-temperature eggs one at a time, beating well after each addition to fully emulsify.

Pour in the yogurt and milk, then add the freshly zested lemon zest, lemon juice, vanilla extract, and honey.

Mix on medium speed until the wet mixture is smooth and fully combined, about 1 minute.

The dairy and citrus create brightness while the honey adds subtle sweetness and moisture.

Step 3: Combine Dry Ingredients and Fold Into Batter

• wet ingredient mixture from Step 2
• 2 cups flour
• 2 tsp baking powder
• 1/2 tsp salt
• 1/4 tsp ground ginger
• 1 1/4 cups squeezed yellow squash from Step 1
• 1/4 cup candied lemon zest

In a separate medium bowl, whisk together the flour, baking powder, salt, and ground ginger.

This pre-mixing ensures even distribution of the leavening agent and spice.

Pour the dry mixture into the wet ingredients from Step 2 and fold gently with a spatula until just combined—do not overmix, as this develops gluten and can make the bread tough.

Fold in the squeezed squash from Step 1 and the chopped candied lemon zest until evenly distributed.

The batter should be thick but pourable.

Step 4: Bake the Bread

• batter from Step 3

Pour the batter from Step 3 into your prepared loaf pan, smoothing the top gently with a spatula.

Place in the preheated 350°F oven and bake for 55-60 minutes until a toothpick inserted into the center comes out clean or with just a few moist crumbs.

The bread should be golden brown on top.

Remove from the oven and let the bread cool in the pan for 10-15 minutes, then turn it out onto a wire rack to cool completely.

I find letting it cool all the way down before glazing prevents the glaze from sliding off.

Step 5: Make the Lemon Glaze and Finish

• 1/2 cup confectioners sugar
• 1 1/2 tbsp lemon juice
• 1 tbsp honey
• cooled bread from Step 4

While the bread cools, prepare the glaze by whisking together the sifted confectioners sugar, lemon juice, and honey in a small bowl until smooth and pourable.

The sifting removes lumps that would make the glaze grainy.

Once the bread is completely cooled, drizzle the glaze generously over the top, letting it pool slightly and drip down the sides.

The glaze will set to a light, glossy finish that adds brightness and sweetness to complement the tender, citrus-forward bread.
