This is the kind of zucchini bread that makes you forget it’s low-carb. It’s tender, lightly sweet, and packed with warm spice. You get all the cozy flavors you expect, with none of the blood-sugar crash.
Whether you enjoy it for breakfast, a snack, or a quick dessert, it’s a simple recipe you’ll want on repeat. Plus, it uses basic keto pantry staples and comes together without fuss.
Ingredients
Method
-
Prep the oven and pan: Heat oven to 350°F (175°C). Line a 9×5-inch loaf pan with parchment and lightly grease the sides.
-
Grate the zucchini: Use the medium holes of a box grater. Measure 1½ cups loosely packed.
-
Drain the zucchini: Place the grated zucchini in a clean kitchen towel and squeeze out as much liquid as you can.
This step prevents a dense, soggy loaf.
-
Mix the dry ingredients: In a large bowl, whisk 2 cups almond flour, 2 tablespoons coconut flour, 1 cup keto sweetener, 2 teaspoons baking powder, 1½ teaspoons cinnamon, and ½ teaspoon salt until no lumps remain.
-
Whisk the wet ingredients: In another bowl, beat 4 large eggs. Whisk in 6 tablespoons melted butter (or coconut oil) and 2 teaspoons vanilla.
-
Combine the batters: Pour the wet mixture into the dry ingredients and stir until just combined. The batter will be thick but spreadable.
-
Fold in zucchini and add-ins: Gently fold in the drained zucchini and any optional nuts or chips.
Don’t overmix.
-
Fill the pan: Scrape the batter into the prepared loaf pan and smooth the top. If you like, sprinkle a few chopped nuts on top for crunch.
-
Bake: Bake 45–55 minutes, or until the top is golden and a toothpick comes out mostly clean (a few moist crumbs are fine). If the top browns too quickly, tent with foil for the last 10–15 minutes.
-
Cool: Let the loaf cool in the pan 15 minutes, then lift out with parchment and cool completely on a rack.
Slicing too early can cause crumbling.
-
Slice and enjoy: Cut into thick slices. Serve as-is, or warm gently and spread with butter or cream cheese.
What Makes This Recipe So Good
- Moist and tender: Grated zucchini keeps the loaf soft without making it soggy.
- Truly low-carb: Almond flour and a keto-friendly sweetener keep the carbs in check.
- Balanced sweetness: Not cloying, just gently sweet with cinnamon and vanilla.
- Easy to customize: Add nuts, sugar-free chocolate chips, or a touch of lemon zest.
- Meal-prep friendly: Freezes well and reheats beautifully.
What You’ll Need
- Almond flour: Finely ground, blanched almond flour gives a tender crumb.
- Coconut flour: A small amount adds structure and prevents sogginess.
- Granulated keto sweetener: Erythritol, allulose, or a monk fruit blend works well.
- Baking powder: For lift. Make sure it’s fresh.
- Ground cinnamon: Classic zucchini bread flavor.
- Salt: Enhances sweetness and overall flavor.
- Eggs: Bind the batter and add richness.
- Butter or coconut oil: Melted and cooled.
- Vanilla extract: Warm, familiar aroma.
- Zucchini: Grated and well-drained.
No need to peel.
- Optional add-ins: Chopped walnuts or pecans, sugar-free chocolate chips, a pinch of nutmeg, or lemon zest.

Keeping It Fresh
- Room temperature: Store in an airtight container for up to 2 days. Add a paper towel to absorb moisture.
- Refrigerator: Keeps 5–6 days.
Let slices come to room temp or warm briefly before serving.
- Freezer: Slice, wrap individually, and freeze up to 3 months. Thaw at room temp or reheat from frozen in a toaster oven.
Why This is Good for You
- Low in carbs, higher in fiber: Almond and coconut flours help keep net carbs down while adding fiber.
- Healthy fats: Almond flour and butter or coconut oil provide satisfying fats that help with fullness.
- Vegetable boost: Zucchini adds micronutrients and moisture without many calories.
- Stable energy: Using a keto sweetener helps reduce sugar spikes and crashes.
What Not to Do
- Don’t skip draining the zucchini: Extra water will make the loaf dense and gummy.
- Don’t pack the flours: Spoon and level them. Packed almond flour leads to a heavy loaf.
- Don’t overbake: Dryness happens fast with nut flours.
Start checking at 45 minutes.
- Don’t cut while hot: It needs time to set. Let it cool for a clean slice.
- Don’t swap sweeteners blindly: Some are sweeter than others. Adjust to taste and follow package conversion notes.
Alternatives
- Nut-free: Replace almond flour with finely ground sunflower seed meal by weight.
Note: it may green slightly due to a reaction with baking powder—still safe to eat.
- Dairy-free: Use coconut oil instead of butter. A splash of almond milk can loosen a too-thick batter.
- Spice variations: Add nutmeg, ginger, or a pinch of cardamom for a warmer profile.
- Lemon-blueberry: Fold in lemon zest and a handful of fresh blueberries (pat them dry). Use allulose to minimize crystallization.
- Chocolate version: Add 2 tablespoons cocoa powder and ⅓ cup sugar-free chocolate chips, reducing almond flour by 2 tablespoons to balance.
FAQ
How many carbs are in a slice?
Actual counts vary by brand and slice size, but a typical slice of this loaf is around 3–4g net carbs when using erythritol or allulose and slicing the loaf into 12 pieces.
Always calculate with your exact ingredients.
Can I make this into muffins?
Yes. Divide the batter among 12 lined muffin cups and bake at 350°F (175°C) for 18–22 minutes, or until a toothpick comes out mostly clean. Start checking at 16 minutes.
Do I have to use both almond and coconut flour?
Using both gives the best texture.
Almond flour provides richness, while coconut flour absorbs moisture and prevents sogginess. If you only use almond flour, the loaf may be wetter and more fragile.
Which sweetener works best?
A 1:1 granulated blend like erythritol and monk fruit works well. Allulose is great for moisture and no cooling aftertaste, but it browns faster, so watch the bake and tent with foil if needed.
Can I grate the zucchini ahead of time?
You can, but it releases water as it sits.
If prepping ahead, store it in a colander in the fridge and squeeze thoroughly before adding to the batter.
Why is my bread crumbly?
Common causes are slicing too soon, not enough moisture, or too much coconut flour. Measure carefully, let it cool fully, and ensure you didn’t overbake.
Can I add protein powder?
Yes, but use a small amount. Replace 2–3 tablespoons of almond flour with an unsweetened whey or egg white protein.
Too much can dry the loaf.
In Conclusion
Keto zucchini bread doesn’t have to be complicated to taste amazing. With well-drained zucchini, a smart blend of almond and coconut flours, and a gentle hand with spices, you get a moist, satisfying loaf that fits your goals. Keep a few slices in the freezer for busy mornings or late-night cravings.
It’s simple, reliable, and hits the spot every time.
