Lemon Poppy Seed Zucchini Bread Recipe tastes bright, moist, and tender with a soft crumb, crunchy poppy seeds, and a sunny lemon glaze on top. It works perfectly for busy home bakers who want a snack or breakfast loaf in about 1 hour from start to finish. I tested this on a sleepy Sunday morning in my tiny kitchen while my kid asked every five minutes if it was done yet, so you know it passed the family test.

Ingredients You’ll Need

Dry ingredients

2 cups all-purpose flour
- Use unbleached if you have it; King Arthur or Gold Medal both work great.
1 cup granulated sugar
- You can swap in ¾ cup coconut sugar for a slightly deeper flavor.
2 tablespoons poppy seeds
1 teaspoon baking powder
½ teaspoon baking soda
½ teaspoon fine sea salt

Wet ingredients

2 large eggs, room temperature
½ cup neutral oil
- Canola, vegetable, or light olive oil all work; avoid strong extra-virgin olive oil.
½ cup plain Greek yogurt or sour cream
- I like full-fat for the best texture, but low-fat still works.
2 teaspoons pure vanilla extract
2 tablespoons fresh lemon zest
- About 2 medium lemons; avoid bottled zest products, they taste dull.
¼ cup fresh lemon juice
- Squeeze it yourself; bottled juice tastes flat in this loaf.

Zucchini

1½ cups grated zucchini, lightly packed
- About 1 medium zucchini; no need to peel.
- If your zucchini feels very watery, pat it once with a paper towel, but do not wring it dry.

Lemon glaze (optional but highly recommended)

1 cup powdered sugar, sifted
2–3 tablespoons fresh lemon juice
½ teaspoon lemon zest, very finely grated

Equipment

1 standard 9 x 5 inch loaf pan
Parchment paper for easy removal
Two medium mixing bowls
Whisk and rubber spatula
Box grater or food processor with grating disc for the zucchini
Microplane or fine grater for the lemon zest
Cooling rack

Tips & Tricks

Measure flour by spooning it into the cup and leveling it so the bread stays soft and not dense.
Use room temperature eggs and yogurt so the batter mixes smoothly and bakes evenly.
Zest the lemons before you juice them, since whole lemons feel easier to handle.
Stir the batter gently and stop as soon as the flour disappears to avoid a tough loaf.
Line the loaf pan with a parchment sling so you can lift the bread out without breaking it.
Check the bread at 45 minutes and tent loosely with foil if the top browns too quickly.
Let the bread cool at least 20 minutes before glazing so the glaze sets instead of sliding off.
Slice with a serrated knife once the loaf cools to keep the crumb neat and tender.

How to Make Lemon Poppy Seed Zucchini Bread Recipe

Step 1: Prep the pan and oven

Preheat your oven to 350°F. Lightly grease a 9 x 5 inch loaf pan, then line it with a strip of parchment that hangs over the long sides. Grease the parchment as well so the bread releases easily.

Step 2: Grate the zucchini

Wash and dry the zucchini. Trim the ends and grate it on the medium holes of a box grater. Lightly fluff it with your fingers and measure 1½ cups without pressing it down hard.

If the zucchini looks extremely wet with liquid pooling at the bottom of the bowl, gently pat it once with a paper towel. Do not squeeze it dry, since the recipe uses that moisture for a tender crumb. Set the zucchini aside.

Step 3: Mix the dry ingredients

In a medium bowl, whisk together the flour, sugar, poppy seeds, baking powder, baking soda, and salt. Break up any sugar clumps with the whisk. Set this bowl aside.

Step 4: Mix the wet ingredients

In a separate large bowl, add the eggs and whisk until they look smooth and slightly frothy. Add the oil, Greek yogurt or sour cream, vanilla, lemon zest, and lemon juice. Whisk until the mixture looks creamy and fully combined.

Step 5: Add the zucchini

Stir the grated zucchini into the wet mixture with a spatula. Fold until the zucchini spreads evenly throughout the bowl. The mixture will look loose and slightly speckled with green and yellow.

Step 6: Combine wet and dry

Pour the dry ingredients into the wet ingredients. Use a spatula to fold the batter together with slow, gentle strokes. Scrape the sides and bottom of the bowl so no dry pockets hide, and stop mixing as soon as no streaks of flour remain.

The batter will look thick but scoopable. If you see a few tiny lumps, leave them, since they smooth out during baking.

Step 7: Fill the pan

Scrape the batter into the prepared loaf pan. Smooth the top with the spatula so it spreads into the corners. Tap the pan once on the counter to release any large air bubbles.

Step 8: Bake

Place the pan on the middle rack of the oven. Bake for 50 to 60 minutes, depending on your oven. Start checking at 45 minutes by inserting a toothpick into the center; it should come out with a few moist crumbs but no wet batter.

If the top browns faster than the center cooks, tent a piece of foil over the pan for the last 10 to 15 minutes. The loaf should feel springy in the center when you press it lightly.

Step 9: Cool the bread

Set the pan on a cooling rack and let the bread cool in the pan for 10 to 15 minutes. Use the parchment sling to lift the loaf out of the pan. Place it directly on the rack and let it cool until just slightly warm before glazing.

Step 10: Mix the lemon glaze

In a small bowl, whisk the powdered sugar with 2 tablespoons of lemon juice. Add more lemon juice a few drops at a time until the glaze reaches a thick, pourable consistency. Stir in the extra lemon zest.

You want the glaze to slowly ribbon off the whisk, not run like water. If it gets too thin, add a spoonful of powdered sugar and whisk again.

Step 11: Glaze and slice

Drizzle the lemon glaze over the cooled zucchini bread, letting it drip down the sides. Give it 10 to 15 minutes so the glaze sets. Slice the loaf with a serrated knife into thick slices for breakfast or thinner slices for snacks.

Serve slightly warm or at room temperature. The lemon poppy seed flavor shines even more the next day.

What to Serve with Lemon Poppy Seed Zucchini Bread Recipe

This lemon poppy seed zucchini bread recipe pairs beautifully with hot coffee, black tea, or a cozy mug of herbal tea. Kids love it with cold milk or a vanilla yogurt cup on the side. You can serve it as part of a brunch spread with scrambled eggs, fresh berries, and a simple fruit salad.

It also works as an afternoon snack with sliced apples or grapes. I like to toast a slice and add a thin swipe of butter or cream cheese when I want it to feel like dessert.
