Zucchini Carrot Muffins are soft, warmly spiced muffins filled with finely shredded vegetables and lightly sweetened with brown sugar. Carrots add gentle sweetness and color, while zucchini contributes moisture without giving the muffins a strong vegetable flavor.
The zucchini is squeezed before mixing so the batter stays moist without becoming wet or gummy. These muffins require no electric mixer and can be refrigerated or frozen for convenient breakfasts and snacks.

Why You'll Love This Recipe
- Squeezing excess liquid from the zucchini prevents wet centers while preserving enough moisture for a tender crumb.
- Finely shredded carrots soften during baking and distribute evenly without leaving firm pieces.
- Brown sugar contributes moisture and a mild caramel flavor that complements the cinnamon and nutmeg.
- Greek yogurt adds tenderness and acidity without making the batter too thin.
- A moderate oven temperature allows the vegetable-filled centers to bake through before the tops become too dark.

How to Make Zucchini Carrot Muffins
Prepare the Oven and Pan
Preheat the oven to 375°F (190°C). Line all 12 cups of a standard muffin pan with paper liners. Lightly grease the liners if they are not labeled nonstick. This step ensures that the muffins do not stick to the liners, making for easier removal once they are baked.
Shred the Vegetables
Finely shred the zucchini and carrots using the small or medium holes of a box grater. Avoid large shreds, which may remain firm or create uneven pockets in the muffins. The finer the shreds, the better they will incorporate into the batter, resulting in a uniform texture.
Remove Excess Zucchini Moisture
Place the shredded zucchini in a clean kitchen towel and squeeze firmly over the sink. Remove the excess liquid without drying the zucchini completely. Measure 1 1/2 cups loosely packed (180 g) after squeezing. This step is crucial for preventing soggy muffins, as excess moisture can lead to a dense texture.
Combine the Dry Ingredients
In a medium bowl, whisk together the flour, baking soda, cinnamon, nutmeg, and salt. Break up any compacted flour and make sure the spices and baking soda are evenly distributed. Properly mixing the dry ingredients ensures that the muffins rise evenly and have a consistent flavor throughout.
Mix the Wet Ingredients
In a large bowl, whisk the eggs and brown sugar until smooth and evenly blended. Add the oil, Greek yogurt, and vanilla, then whisk until the mixture looks glossy and no streaks of yogurt remain. This mixture should be well combined to ensure that the muffins have a uniform sweetness and moisture.
Add the Vegetables
Stir the squeezed zucchini and shredded carrots into the wet mixture. Separate any clumps so the vegetables are evenly distributed. This step helps to ensure that every muffin has a good balance of vegetables, enhancing both flavor and texture.
Make the Batter
Add the dry ingredients to the vegetable mixture. Fold gently with a flexible spatula until only a few small flour streaks remain. Fold in the optional walnuts or pecans, if using, and stop mixing as soon as the batter is uniform. It should be thick, moist, and scoopable. Overmixing can lead to tough muffins, so be careful to mix just until combined.
Fill the Muffin Cups
Divide the batter evenly among the 12 prepared muffin cups. Each cup should be about three-quarters full. Smooth any tall peaks lightly with the back of the scoop. This helps the muffins rise evenly and prevents them from forming large domes.
Bake the Muffins
Bake on the center rack for 20 to 24 minutes. The muffins are done when the tops are lightly golden, the centers spring back when gently pressed, and a toothpick inserted in the middle comes out clean or with a few moist crumbs. Baking them at the right temperature is essential for achieving the perfect texture.
Check for Doneness
If wet batter clings to the toothpick, continue baking for 2 minutes before checking again. If the tops are browning too quickly, place a loose sheet of aluminum foil over the pan. This step helps to prevent over-baking the tops while ensuring the centers are fully cooked.
Cool in the Pan
Place the muffin pan on a wire rack and let the muffins cool for 10 minutes. They will be delicate while hot, so removing them immediately may cause the sides to break. Allowing them to cool slightly helps them set and makes them easier to handle.
Finish Cooling
Transfer the muffins to the wire rack and cool for at least 10 more minutes before serving. The crumb will continue to set as the muffins cool. This final cooling step is important for achieving the desired texture and flavor.
Tips for Success
- Measure the zucchini after squeezing because its weight and volume change substantially when excess water is removed.
- Grate the carrots finely so they soften during the relatively short baking time.
- Do not overmix the batter. Excess mixing can create tough muffins with tunnels through the crumb.
- Use fresh baking soda. Old leavening can leave the muffins short, dense, or gummy.
- Check the muffins near the lower end of the baking range, especially when using a dark metal pan.
- Let the muffins cool before peeling away the liners, as the moist crumb releases more cleanly once it has set.
Storage, Freezing, and Make-Ahead Instructions
Let the Zucchini Carrot Muffins cool completely before storing them. Place them in an airtight container lined with a dry paper towel and keep them at room temperature for up to 2 days. For longer storage, refrigerate the muffins in an airtight container for up to 5 days. Let a refrigerated muffin stand at room temperature for 15 to 20 minutes before serving, or microwave it for about 10 seconds.
To freeze, wrap each completely cooled muffin individually and place the wrapped muffins in a freezer-safe bag or container. Freeze for up to 3 months. Thaw at room temperature for 1 to 2 hours or overnight in the refrigerator. The zucchini and carrots can be shredded up to 1 day in advance and refrigerated separately in airtight containers. Squeeze the zucchini and mix the batter shortly before baking. Fully mixed batter should not be stored because the baking soda begins reacting once it contacts the wet ingredients.
FAQ
Can I make Zucchini Carrot Muffins ahead of time?
Yes. Bake the muffins up to 1 day before serving and store them after they have cooled completely. They can also be frozen for up to 3 months.
Do I need to peel the zucchini?
No. The skin is thin and softens during baking. Leave it on for color and to avoid unnecessary preparation.
Why are my muffins soggy in the center?
The zucchini may not have been squeezed thoroughly, the batter may have contained too many vegetables, or the muffins may be underbaked. Measure the vegetables carefully and bake until a toothpick no longer shows wet batter.
Can I add raisins?
Yes. Fold in up to 1/2 cup (75 g) of raisins instead of the optional nuts. Raisins will make the muffins sweeter and add chewy pockets throughout the crumb.
Can I make mini zucchini carrot muffins?
Yes. Divide the batter among lined or greased mini muffin cups and bake at 350°F (175°C) for approximately 11 to 14 minutes. Begin checking early because mini muffins bake quickly.
