Quick Answer
The best spiced zucchini bread uses 2 cups of grated zucchini left unsqueezed, a half and half blend of melted butter and neutral oil for richness and softness, and a mix of white and brown sugar for flavour and moisture.
Bake at 175 C / 350 F for 55 to 65 minutes in an 8.5 by 4.5 inch loaf pan lined with parchment. The loaf rises tall, the crumb stays moist for days, and the warm cinnamon and nutmeg make it taste like fall in any season.
Cool completely before slicing or the centre will gum up.
Do not squeeze the zucchini
Most online recipes tell you to wring the grated zucchini in cheesecloth before adding it. That works for a savoury fritter, but for a quick bread it removes the moisture that keeps the crumb tender.
This recipe is balanced around naturally hydrated, freshly grated zucchini. The water content is baked into the math. If you squeeze it dry, you end up with a heavy, slightly dry loaf that has nothing to do with the soft, moist zucchini bread you actually want.
Why oil and butter together
Oil based quick breads stay soft for days because oil remains liquid at room temperature. But pure oil tastes flat.
Butter delivers flavour and the toasty notes you expect from a baked good, but a loaf made with all butter goes dry within 24 hours.
By using half melted butter and half neutral oil, you get the best of both: rich flavour on day one and a moist crumb on day three.

Method
1. Heat the oven and prep the pan
Preheat the oven to 175 C / 350 F. Grease an 8.5 by 4.5 inch loaf pan, then line the bottom with a parchment sling so you can lift the loaf out cleanly.
2. Whisk the dry ingredients
In a large bowl, whisk together the flour, baking soda, baking powder, salt, cinnamon, and nutmeg until evenly distributed. This step matters because zucchini bread is mixed gently and you will not stir long enough to break up lumps later.
3. Mix the wet ingredients
In a second large bowl, whisk the melted butter and oil together with both sugars until smooth. Add the eggs one at a time, then the vanilla, whisking until the mixture looks slightly lighter in colour. Stir the grated unsqueezed zucchini in last.
4. Fold and pour
Pour the wet mixture over the dry. Use a rubber spatula to fold gently just until the flour streaks disappear. If you are using nuts, fold them in now. Stop the moment the batter looks combined. Overmixing develops gluten and makes the bread tough and rubbery.
5. Bake
Pour the thick batter into the prepared pan and smooth the top. Bake 55 to 65 minutes. Start checking at 55. The loaf is done when a wooden skewer in the centre comes out clean or with a few moist crumbs.
6. Cool fully
Rest the loaf in the pan for 10 minutes, then lift it out by the parchment sling and cool completely on a wire rack. Slicing while warm will smear the soft centre. Wait at least an hour.
Storage
Wrap the cooled loaf tightly in plastic and store at room temperature for 3 days, or in the fridge for a week. It freezes beautifully. Slice first, wrap each slice, and freeze. Thaw on the counter or microwave 20 seconds.
Variations
- Chocolate chip: Fold in 1 cup of chocolate chips. The bitterness pairs with the warm spices.
- Cream cheese swirl: Whisk 4 oz cream cheese with 3 tbsp sugar and 1 egg yolk, spoon onto the batter, and swirl gently with a knife before baking.
- Carrot zucchini: Replace 1 cup of zucchini with grated carrot for a hybrid spiced loaf.
- Gluten free: Swap the all purpose flour 1:1 with a good gluten free baking blend that contains xanthan gum.
Troubleshooting
- Loaf sinks in the middle. Underbaked, or too much zucchini. Use a kitchen scale and check doneness with a skewer.
- Tough rubbery crumb. Overmixed. Fold gently until just combined.
- Dense and heavy. The leaveners were old. Replace baking soda and baking powder every 6 months.
- Top cracks too much. Normal for quick breads. The crack is a sign of a strong rise, not a failure.
Frequently asked questions
Do I peel the zucchini?
No. The skin is thin and disappears into the loaf. The flecks of green also look pretty in the slice.
Can I use frozen grated zucchini?
Yes, but thaw it and drain only the obvious pooled liquid. Do not wring it dry. Frozen zucchini releases more water than fresh, so dab off any excess that pools in the bowl.
Why both baking soda and baking powder?
Baking soda neutralises the acid in brown sugar and helps browning. Baking powder provides the main lift. Together they create a tall, evenly risen loaf.
Choosing the right zucchini
Small to medium zucchini (6 to 8 inches long) is what you want. The skin is tender, the seeds are small, and the flesh is dense. Giant late season zucchini bigger than a forearm is woody, watery, and full of large seeds that turn slimy when grated. If you only have large zucchini, scoop out the spongy seed cavity with a spoon before grating.
One medium zucchini yields roughly 2 cups of grated flesh, exactly what this recipe needs. If you have extra, freeze it in 2 cup portions for future loaves. Frozen grated zucchini bakes almost identically to fresh, with one small adjustment: dab off any obvious pooled liquid after thawing without squeezing.
Make it your own
Once you have the base recipe dialled in, treat it as a platform. Swap half the oil for melted coconut oil for a tropical note. Add 1 teaspoon of cardamom and a tablespoon of fresh grated ginger for a chai version. Stir in a cup of grated apple alongside the zucchini for extra moisture and a hint of orchard flavour. The chemistry is forgiving as long as you keep the total liquid and fat amounts roughly the same.
The takeaway
Skip the squeeze, weigh your flour, blend butter with oil, and treat the batter gently. That formula bakes a zucchini bread that rises tall, slices clean, stays moist for days, and tastes like the best version of every coffee shop quick bread you have ever had.
