Zucchini Bread Recipe: Moist and Easy

The best zucchini bread recipe uses lightly drained grated zucchini, a light-colored 9-by-5-inch metal loaf pan, and a moderate oven temperature so the center stays moist without collapsing. Drain only enough liquid to prevent a wet middle: squeeze the zucchini once in a clean towel, measure it afterward, and bake until the center reaches about 200–205°F (93–96°C).

This easy zucchini bread makes one substantial loaf with a tender crumb, mild spice, and enough moisture to stay fresh for several days. The most important choices are the zucchini’s final weight, the pan’s actual dimensions, and the doneness test—not simply the number of minutes on the timer.

Zucchini Bread Recipe at a Glance

Ingredients

• 2 cups finely grated zucchini, approximately 250–300 g before draining
• 1¾ cups (220 g) all-purpose flour
• ½ cup (100 g) granulated sugar
• ½ cup (100 g) packed light brown sugar
• 2 large eggs, about 100 g without shells
• ½ cup (120 ml) neutral oil, such as canola, sunflower, or vegetable oil
• 1 teaspoon vanilla extract
• 1½ teaspoons ground cinnamon
• ½ teaspoon ground nutmeg, optional
• 1 teaspoon baking soda
• ½ teaspoon baking powder
• ¾ teaspoon fine salt
• ½ cup (60–85 g) chopped walnuts, pecans, or chocolate chips, optional

The zucchini amount is measured before draining because different squash release different amounts of water. After draining, aim for approximately 1½ cups, or about 220–250 g. A very dry final weight can produce a less tender loaf, while a dripping-wet portion can leave the center gummy.

How to Drain Grated Zucchini Correctly

Grated zucchini should be lightly drained, not wrung completely dry. The goal is to remove free liquid that would thin the batter while keeping the water held inside the vegetable’s fine shreds.

• Grate the zucchini on the large holes of a box grater. There is no need to peel a young zucchini.
• Transfer the shreds to a clean kitchen towel, cheesecloth, or a fine-mesh strainer.
• Gather the towel and press or squeeze once over a bowl for about 10–15 seconds.
• Stop when the zucchini no longer releases a steady stream of liquid. Do not twist aggressively until the shreds are dry.
• Measure the drained zucchini and add it to the batter immediately.

If the zucchini is unusually watery, spread it on the towel and let it stand for five minutes before the light squeeze. If it is small, firm, and relatively dry, pressing it once may be enough. Do not salt the zucchini to draw out moisture; salt can make the bread taste overly seasoned and can remove more water than this recipe needs.

Method

1. Prepare the pan and oven

Heat the oven to 350°F (175°C), with a rack positioned in the lower-middle portion. Grease a 9-by-5-inch loaf pan and line the long sides and base with parchment, leaving an overhang for lifting the loaf out.

A true 9-by-5-inch pan has roughly 20% more surface area than an 8½-by-4½-inch pan. The smaller pan produces a taller loaf and usually needs an additional 8–15 minutes of baking. Fill either pan only about two-thirds to three-quarters full; excess batter can rise over the rim or remain underbaked in the middle.

2. Combine the dry ingredients

In a medium bowl, whisk together the flour, cinnamon, nutmeg if using, baking soda, baking powder, and salt. Mixing these ingredients first distributes the leaveners so the loaf rises evenly rather than developing dense or bitter pockets.

3. Mix the wet ingredients

In a large bowl, whisk the eggs, granulated sugar, brown sugar, oil, and vanilla until smooth. Add the lightly drained zucchini and stir until evenly distributed.

Oil gives zucchini bread a moist texture for several days because it remains liquid after cooling. Melted butter can be substituted for part or all of the oil, but the loaf will have a firmer texture when chilled and a more pronounced dairy flavor.

4. Fold the batter

Add the dry ingredients to the wet mixture and fold with a spatula just until no large streaks of flour remain. Fold in the nuts or chocolate chips if using. The batter should be thick, uneven, and spoonable; a few small lumps are preferable to overmixing.

Stirring too long develops gluten and can make the finished bread chewy or compact. Once the flour disappears, stop mixing.

5. Fill the pan and adjust for its size

Scrape the batter into the prepared pan and smooth the surface. For a 9-by-5-inch light metal pan, begin checking at 50 minutes. For an 8½-by-4½-inch pan, begin checking at 58 minutes. A glass or ceramic pan usually needs approximately 5–10 additional minutes at the same oven temperature, but it may brown more slowly at first and then retain heat after removal.

6. Check for a moist but baked center

Insert a wooden skewer or cake tester into the center, avoiding a walnut or chocolate chip. It should emerge with a few moist crumbs attached, but not with shiny liquid batter. If using an instant-read thermometer, check the center from the side; 200–205°F (93–96°C) indicates that the crumb has set.

If the top is brown but the center is still wet, loosely cover the loaf with foil and continue baking in 5-minute increments. Foil slows browning while allowing the interior to finish. Do not increase the oven temperature to hurry the process, because that can create a thick crust and an underbaked center.

7. Cool before slicing

Let the loaf cool in the pan for 15 minutes, then lift it onto a wire rack and cool for at least 60 minutes before slicing. The crumb continues to set as it cools. Cutting while hot releases steam and can make an otherwise properly baked loaf appear gummy or cause slices to collapse.

How to Keep the Center Moist Without Sinking

A sunken zucchini bread usually has too much liquid, too much leavening, an underbaked center, or a batter that was mixed too vigorously. Use the following checks:

• Drain consistently: after a light squeeze, use about 1½ cups of zucchini rather than adding every drop of liquid from the bowl.
• Weigh flour when possible: 220 g is more reliable than an unpacked or heavily packed cup. Too little flour leaves the structure weak.
• Do not overfill: batter should not rise above three-quarters of the pan’s height.
• Use fresh leaveners: baking soda and baking powder that have been open for many months may produce weak or uneven lift.
• Avoid opening the oven early: wait until at least 45 minutes have passed before checking a 9-by-5-inch loaf.
• Let the batter rest only briefly: bake soon after mixing so the chemical leaveners work in the oven rather than losing strength on the counter.

For a concrete example, suppose a recipe starts with 300 g grated zucchini. A light squeeze may remove 50–70 g of free liquid, leaving 230–250 g of zucchini. That is a useful range for this formula. If aggressive squeezing leaves only 170 g, the bread may be less tender; if nearly all 300 g goes into the bowl dripping wet, add 10–15 minutes to the baking time and expect a greater risk of sinking.

Variations That Keep the Recipe Balanced

Walnut zucchini bread

Add ½ cup chopped walnuts or pecans. Toasting the nuts for 6–8 minutes at 350°F before cooling them improves flavor, but cool them fully before folding them into the batter.

Chocolate-chip zucchini bread

Add ½ cup semisweet chocolate chips. Tossing the chips with one teaspoon of the measured flour can help them remain suspended, although a thick batter is the main factor that prevents sinking.

Less-sweet zucchini bread

Reduce the total sugar from 200 g to 160 g, but do not remove all of the brown sugar. Sugar contributes sweetness, tenderness, moisture retention, and browning, so a large reduction produces a drier, firmer loaf.

Storage and Ownership Realities

Once completely cool, wrap the loaf tightly or place it in an airtight container. It keeps at room temperature for up to three days, in the refrigerator for up to one week, or in the freezer for about three months. Refrigeration can make the crumb feel firmer, so bring slices to room temperature before serving.

For freezing, slice the loaf first and place parchment between slices. Individual pieces thaw at room temperature in about 30–60 minutes. The crust may soften after storage; reheating a slice for 10–15 seconds in a microwave can restore some of its tenderness, but avoid overheating because the zucchini can make the crumb rubbery.

The most common equipment issue is an inaccurate oven rather than a defective recipe. An inexpensive oven thermometer can reveal a temperature difference of 25°F or more. Also check that the loaf pan is not heavily scratched, warped, or much smaller than its stated size; dark, thin, or undersized pans are more likely to create a hard crust or a raw center.

Frequently Asked Questions

Do I have to peel the zucchini?

No. The skin of a young zucchini is thin and softens during baking, while the green flecks add color. Peel only a very large zucchini if its skin is tough or waxy, and remove the seeds if they are large and firm.

Can I use frozen grated zucchini?

Yes, but thaw it completely and drain it more thoroughly than fresh zucchini. Measure about 1½ cups, or 220–250 g, after thawing and squeezing. Frozen zucchini releases extra water as it defrosts, so adding it while still icy can make the loaf bake unevenly.

Why is my zucchini bread wet in the middle?

The usual causes are excess zucchini liquid, an undersized pan, or insufficient baking time. Return the loaf to a 350°F oven, loosely cover the top with foil, and bake in 5-minute increments until a tester shows moist crumbs rather than liquid batter. Let it cool fully before deciding whether the crumb is actually underbaked.

Can I bake this recipe in an 8-by-4-inch loaf pan?

Yes, but the pan may be too full for the entire batch. Fill it no more than three-quarters full and bake the remaining batter as muffins. Begin checking the loaf around 60 minutes, since its greater height makes the center take longer to set.

How do I know when zucchini bread is done without a thermometer?

Insert a skewer into the center of the loaf, avoiding any add-ins. It should come out with several moist crumbs but no streak of raw batter, and the top should spring back lightly when pressed. A visible crack along the top is normal and does not mean the loaf is dry.

Can I replace the oil with applesauce?

You can replace up to half of the oil with an equal volume of unsweetened applesauce, but the result will be less rich and slightly more cake-like. Replacing all the oil may make the loaf softer at first but can also make it gummy or less durable during storage. If using sweetened applesauce, reduce the granulated sugar by about two tablespoons.
