These lemon zucchini muffins are the kind you bake once and keep making on repeat. They’re soft, sunny with citrus, and just sweet enough to feel like a treat without being heavy. Zucchini melts right into the batter, giving you a fluffy crumb and extra moisture without a strong veggie taste.
The lemon zest and juice bring a clean, fresh finish that wakes up every bite. If you love light, bakery-style muffins with a bright twist, these are your new go-to.
What Makes This Recipe So Good
- Moist and tender: Grated zucchini adds natural moisture, so the muffins stay soft for days.
- Balanced flavor: Fresh lemon zest and juice bring zing without overpowering the vanilla and butter.
- Quick to make: One bowl for wet, one for dry, and you’re done in under an hour.
- Not too sweet: These work for breakfast, snacks, or an easy dessert.
- Foolproof texture: A little yogurt and oil keep them from drying out or getting dense.
What You’ll Need
- 1 3/4 cups (220g) all-purpose flour
- 3/4 cup (150g) granulated sugar
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon fine salt
- 1 tablespoon fresh lemon zest (from 1–2 lemons)
- 2 tablespoons fresh lemon juice
- 2 large eggs, room temperature
- 1/2 cup (120ml) neutral oil (canola, vegetable, or light olive oil)
- 1/2 cup (120g) plain Greek yogurt or sour cream
- 1 teaspoon vanilla extract
- 1 1/2 cups finely grated zucchini (about 1 medium; lightly packed)
- Optional: 1/2 cup mini white chocolate chips or blueberries
- Optional lemon glaze: 1/2 cup powdered sugar + 1–2 tablespoons lemon juice
Instructions
- Prep the pan and oven: Heat the oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or lightly grease.
- Grate the zucchini: Use the fine holes of a box grater.
Spread the grated zucchini on a clean towel and gently squeeze out excess moisture. You want it damp, not dripping.
- Mix dry ingredients: In a large bowl, whisk flour, sugar, baking powder, baking soda, and salt. Rub the lemon zest into the sugar with your fingers before whisking to release more citrus oils.
- Mix wet ingredients: In a separate bowl, whisk eggs, oil, yogurt, vanilla, and lemon juice until smooth.
- Combine: Pour the wet ingredients into the dry.
Stir with a spatula until just a few streaks of flour remain.
- Fold in zucchini: Add the grated zucchini (and chips or berries, if using). Fold gently until evenly distributed. Do not overmix.
- Fill the cups: Divide the batter evenly among the 12 muffin cups, filling each about 3/4 full.
- Bake: Bake 18–22 minutes, until the tops spring back and a toothpick inserted in the center comes out clean or with a few moist crumbs.
- Cool: Let muffins cool in the pan for 5 minutes, then transfer to a rack to cool completely.
- Optional glaze: Whisk powdered sugar with lemon juice to a pourable consistency.
Drizzle over cooled muffins for extra zing.
Keeping It Fresh
- Room temperature: Store in an airtight container for up to 3 days. Slip in a paper towel to absorb excess moisture.
- Refrigerator: Keeps 5–6 days. Bring to room temp or warm 10–15 seconds in the microwave before serving.
- Freezer: Wrap each muffin and freeze in a zip-top bag for up to 3 months.
Thaw at room temp or warm in a low oven.
- Glaze later: If freezing, glaze after thawing to keep the tops fresh.
Health Benefits
- Veggie boost: Zucchini adds fiber, potassium, and vitamin C with minimal calories.
- Lower sugar than cupcakes: These muffins satisfy a sweet craving without heavy frosting.
- Healthy fats: Using oil instead of all butter gives a tender crumb and can be easier on digestion.
- Protein option: Greek yogurt adds a bit of protein and helps with satiety.
- Natural brightness: Lemon adds flavor without extra fat, keeping things light and refreshing.
Pitfalls to Watch Out For
- Skipping the squeeze: Too-wet zucchini can make gummy centers. Gently squeeze before adding.
- Overmixing: Stir only until combined. Overmixing activates gluten and leads to tough muffins.
- Overbaking: Check at 18 minutes.
Dry edges or a dark top means they went too long.
- Too much lemon juice: More isn’t always better. Extra acid can affect rise and texture. Stick to the amounts listed.
- Large shreds: Finely grate the zucchini for even texture and better moisture distribution.
Recipe Variations
- Lemon Poppy Seed: Add 1 tablespoon poppy seeds and increase lemon zest by 1 teaspoon.
- Blueberry Lemon: Fold in 1 cup fresh blueberries tossed in 1 tablespoon flour to prevent sinking.
- Lemon Coconut: Add 1/2 cup shredded coconut and a pinch of coconut extract.
- Gluten-Free: Use a 1:1 gluten-free all-purpose blend with xanthan gum.
Watch the bake time closely.
- Dairy-Free: Swap yogurt for coconut yogurt and use a neutral oil. The texture stays moist and tender.
- Extra Lemon: Brush warm muffins with a quick lemon syrup (equal parts lemon juice and sugar, heated to dissolve) for a bright finish.
FAQ
Do I need to peel the zucchini?
No. Leave the skin on for color and nutrients.
It softens completely during baking and you won’t notice it.
Can I use bottled lemon juice?
Fresh is best for both flavor and aroma. Bottled juice can taste flat. If it’s all you have, use it in the batter but keep fresh zest.
How do I know the muffins are done?
Look for lightly golden tops that spring back when pressed.
A toothpick should come out clean or with moist crumbs, not wet batter.
Can I make these with whole wheat flour?
Yes, swap up to half the all-purpose flour with white whole wheat flour. The muffins will be a bit heartier but still moist.
What if my batter seems too thick?
It should be thick but scoopable. If it’s dry, add 1–2 tablespoons milk or an extra tablespoon lemon juice to loosen slightly.
Can I make mini muffins?
Absolutely.
Bake in a mini muffin pan for 10–12 minutes, checking early to avoid overbaking.
Why did my muffins sink?
Likely due to overmixing, old leaveners, or too much liquid from unsqueezed zucchini. Measure carefully and use fresh baking powder and soda.
How can I get a taller muffin top?
Fill cups 3/4 full, start at 400°F (200°C) for 5 minutes, then reduce to 350°F to finish baking. This jump-starts lift.
Watch closely to prevent overbrowning.
