The best way to use up a zucchini glut
If you grow zucchini, or courgettes, you will know the problem - for a few weeks in late summer they arrive faster than anyone can eat them and then there are only so many you can give away.
Zucchini banana bread is a great way to use up a glut and it freezes beautifully, so you can enjoy this delicious loaf for months to come.
You can also freeze the grated zucchini itself, packing it into measured portions, then it is ready to use straight from frozen whenever you fancy a loaf.
How to prepare the zucchini
No need to peel - the skin is where a lot of the nutrients and colour are, plus it will soften completely as the bread bakes. Just wash, dry and trim both ends.
Use a grater - use the coarse side of a box grater or a food processor for speed. Two medium zucchini give you roughly the two cups you need.
The question of draining (degorging) - zucchini is around 90% water and the moisture content is important to how the loaf bakes. This recipe deliberately keeps the moisture in because this is what makes the bread so soft and tender. The trade-off is that a wetter batter needs longer in the oven.
If your zucchini is very fresh and juicy, or you might prefer a shorter, more predictable bake, squeeze the grated zucchini in a clean tea towel or some kitchen paper first to remove the excess liquid. You will lose a little tenderness and gain a firmer crumb but you will have a more reliable bake time. Either approach works, it is just a matter of preference.
About the oven temperature
The baking temperature (325°F/165°C) is admittedly on the lower side for a quick bread and many banana and zucchini breads bake higher (350°F/175°C), but lower and slower is the way to go here. It gives a more even bake, a better crust and less risk of the outside setting before the wet middle cooks through. For a moist, undrained zucchini batter, this low temperature is correct as it gives the wet centre more time to cook without burning the outside.
The trade-off of a lower temperature for a wet batter means a longer bake time. Use a toothpick to check the loaf is cooked through. Turn up the heat to 350°F/175°C for a faster, more predictable bake, but you will get less of a crust (which is in my option, is the yummiest part).
How to tell when zucchini bread is done
If you have made zucchini bread before and found it took far longer than the recipe said, you are not doing anything wrong, it is the water content of the zucchini. The fresher the zucchini, the higher its water content.
Because this recipe keeps the moisture in the zucchini (rather than draining it), the batter will be wetter than a standard banana bread, taking longer to set. Depending on how juicy your zucchini is, your loaf may need anywhere from 15 to 30 minutes beyond the stated time. Ovens vary too and loaf tins hold heat differently.
So don't rely on the clock. Rely on these signs to check the bread is actually done:
- A skewer or toothpick pushed into the very centre comes out clean, with no wet batter clinging to it (a few moist crumbs are fine).
- The top is domed, firm to a light press and springs back rather than leaving a dent.
- The loaf has come away slightly from the sides of the tin.
If the top is browning too fast before the middle is cooked, lay a piece of foil loosely over it and keep baking. If in doubt, give it another ten minutes as an underbaked middle is the one thing you can't fix afterwards.
Ingredients
These are the ingredients you will need for zucchini banana bread.

- zucchini - gives flavour, a chewy texture and moisture.
- banana - adds flavour, sweetness and moisture
- brown sugar - add richness
- white sugar
- egg - use at room temperature for better mixing
- flour - plain all purpose flour
- baking powder
- baking soda - also known as soda bicarbonate
- cinnamon & vanilla - spiciness and flavour
- salt - enhances the flavours
See the recipe card below for quantities.
Instructions
Prepare the flour mixture.

In a separate bowl beat the egg, butter and vanilla with both sugars.

Wash two medium sized zucchini, pat dry and trim off both ends, then shred using a cheese grater or food processor.

Fold the sifted ingredients into the egg mixture till just combined then gently stir in bananas and zucchini.
Pour into the greased pan and bake for 60 minutes or till a toothpick inserted in the middle comes out clean.
Cooking time: as oven performance varies, insert a toothpick into the center of the bread and it should come out clean when it is done.
Leave the bread to cool in the pan before turning out.

Top tips
- The fresher the zucchini, the more moisture it contains, making your zucchini bread tender and delicious.
- A ripe banana reduces the need for any more butter or sugar
- Although some recipes call for extracting excess moisture from the zucchini before adding to the batter, we prefer not to do this as the moisture makes a more delicious soft and tender bread.
- There is no need to peel the zucchini before grating. There's a lot of good stuff in the skin!
- When combining the wet and dry ingredients, take care not to over mix the mixture or the bread will become tough and dense. Mix till the batter is just moistened.
- Insert a toothpick into the center of the bread and it should come out clean when it is done.
- Leave the bread to cool in the pan before turning out.

Substitutions
If you are running low on a certain ingredient or catering for any dietary requirements try these substitutions:
- Running low on zucchini? - no worries, just top it up with shredded apple or pumpkin.
- Make it sugar free - replace the white and brown sugars with the same quantity of maple syrup or honey.
Variations
Here are a few ways you can adjust the ingredients to suit your taste:
- Chocolate - mix in ½ cup chocolate chips when adding zucchini to the mixture.
- Nuts - stir in ½ cup crushed roasted walnuts or pecans when adding the zucchini to the mixture for crunchiness.
Turn it into muffins
This batter works beautifully as muffins and they bake much faster and more reliably than a loaf. This is handy if the variable loaf timing has caught you out before.
Spoon the batter into a lined or greased 12-hole muffin tin, filling each about three-quarters full, then bake at the same temperature (325°F / 165°C) for 20-25 minutes, till a toothpick comes out clean and the tops spring back. It makes around 12 muffins. They freeze well and are perfect for lunchboxes.
Equipment
How your zucchini bread turns out will depend on the type of loaf pan you use.
A loaf tin is easy to bake in and forms a great shape for easy slicing.
The shape - A good quality loaf pan should be narrow (not wide) with straight (not slanted) sides.
Material - Select a pan made from a heavy material so heat distributes evenly and the bread cooks uniformly. A non-stick metal pan would be ideal. I use a toughened, PFOA-free, non-stick pan by Le Creuset and my bread loaves cook evenly and are easy to remove. Glass containers may heat up too quickly causing the bread to burn on the outside and not cook properly inside.
Choose a non-stick pan and grease the sides and bottom so the bread doesn't stick when trying to get it out.
To release the bread - once the loaf has cooled, turn the tin upside down over a plate and tap the base of the tin gently to release the bread. Do not use a metal or sharp instrument as this will damage the non-stick quality of the tin.
Serving
Slice and serve when freshly baked for best results, or at room temperature.
To reheat toast a slice in a dry skillet on low heat, or place on a baking tray and reheat in a low oven.
Storing leftovers
Cover and store the bread in a cool part of the kitchen or in the fridge, it will keep for up to 3 days.
Wrap the zucchini bread and freeze in slices for convenience. Place the wrapped slices in a freezer bag and freeze for up to 2 months, then thaw at room temperature.
FAQs
Not for this recipe as the moisture is what makes the bread so soft and tender. But it does mean a longer, less predictable bake. If you would prefer a quicker, more reliable bake and a firmer crumb, squeeze the grated zucchini dry in a tea towel first.
This is almost always because the batter is still wet from the zucchini and it simply needed longer in the oven. Keep baking till a toothpick pushed into the centre comes out clean - cover the top with foil if it is browning too fast. It can take 15-30 minutes longer than stated depending on your zucchini and oven.
This is to do with the amount of moisture in the zucchini. Fresher, juicier zucchini holds more water, which extends the bake time. Go by the toothpick test rather than the clock, and don't be afraid to give it extra time.
No, skin on is best. It will soften as it bakes, adding nutrients and a bit of colour.
Yes, absolutely. Thaw the frozen zucchini, squeezing out the excess water (frozen zucchini releases more water than fresh), then use as normal. As you are draining it, the bake time will be more predictable.
Yes, and several readers have halved the sugar with great results. The banana keeps it sweet enough for most tastes, even with less added sugar.
Absolutely, see the muffin instructions above. They bake in 20-25 minutes, a more predictable bake time than the loaf.
Keep covered in a cool spot or the fridge for up to 3 days, or freeze in slices for up to 2 months then thaw at room temperature.

Susan says
This bread was delicious!!
However, I did encounter a concern with the moisture content of the zucchini causing a more extended bake time than stated on the recipe.
I will make this again but maybe let some moisture drain off first....
Nicole Shroff says
Hi Susan, Thank you and I have just updated the baking time.
Dorothy says
I cooked it for 40 minutes but if didn’t seem baked inside so I put it back in the oven for another 20 minutes!
Elaine says
I made this loaf too and practically had to double baking time.
Nicole Shroff says
Hi Elaine, I have just updated the baking time. As oven performance varies its always best check by inserting a toothpick into the centre till it comes out clean, I hope that helps.
Nicole Shroff says
Hi Dorothy, I have just updated the baking time, I hope this helps.
Don says
I will not be making this recipe due to the measurements being in grams. Other than that it sounds tasty!
Nicole Shroff says
Hi Don, measurements are also listed in cups next to the ingredients, I hope this helps.
Barb says
I put mine in at 325 as the recipie says but took much longer to cook,so I was wondering if that should be at 350 degrees??
Nicole Shroff says
Hi Barb, we find 325F cooks the inside perfectly and makes a delicious crispy crust, however as ovens to vary slightly it might take slightly longer.
Sher H. says
I made them in a muffin pan and cut the sugar in half (my family doesn't like things too sweet). Awesome recipe, I'll be making this again!
Nicole Shroff says
Thanks so much Sher!
Gail says
I did the recipe as is and it was delicious. I am questioning
one of the ingredients that called for 1/2 tsp baking flour
and I assumed it meant baking powder and that is what I
did. Was I correct?
Nicole Shroff says
Thanks Gail that's correct, I have corrected it now.
Laura Bates says
very good. Although it took amost hour and half to cook.
Nicole Shroff says
Thanks Laura, I have just updated the baking time.
