Gluten-Free Zucchini Cheddar Muffins are savory muffins built on a measure-for-measure gluten-free flour blend, grated zucchini, and sharp cheddar folded straight into the batter. They bake up golden on top and tender inside, no gummy center if you follow one rule: squeeze the zucchini first.
I made a soggy batch early on. Skipped the squeeze, added the zucchini wet, and the middle stayed dense even after 25 minutes in the oven. Now I always wring it out in a clean towel first.
These muffins are savory, not sweet. Cheesy edges. A little crisp on top from the extra cheddar sprinkled on before baking. Soft and moist inside, held together by eggs and a flour blend that doesn’t taste like cardboard.
They work for breakfast, lunchboxes, or a snack next to soup, much like these banana walnut breakfast muffins. I keep a batch in the freezer most weeks for my kid’s lunch.
Why You’ll Love This Recipe
- Freezes well for fast weekday breakfasts
- Uses one bowl for wet, one for dry
- Sneaks a full cup of zucchini into a savory muffin
- No gums or xanthan to add, the flour blend has it built in
Ingredient Notes
- Gluten-free flour blend: Use a measure-for-measure blend like Bob’s Red Mill 1:1 that already contains xanthan gum, not a straight gluten-free flour.
- Zucchini: Grate on the large holes of a box grater, then squeeze in a clean towel until you’ve pressed out 2 to 3 tbsp of liquid.
- Sharp cheddar: Shred a block yourself if you can, pre-shredded cheese has an anti-caking coating that keeps it from melting into the batter.
- Olive oil: Melted butter works as a 1:1 swap and adds a slightly richer flavor.
- Whole milk: Oat milk works if you need to cut dairy from this part of the recipe, though the cheese keeps the muffins from being fully dairy-free.
Soft and Cheesy Gluten-Free Zucchini Cheddar Muffins
Ingredients
Method
- Heat the oven to 190 C / 375 F. Line a 12-cup muffin tin with paper liners or grease it well.
- Grate the zucchini on the large holes of a box grater. Wrap it in a clean kitchen towel and squeeze hard until you’ve pressed out 2 to 3 tbsp of liquid.
- Whisk the gluten-free flour, baking powder, baking soda, salt, garlic powder, and pepper together in a mixing bowl.
- In a second bowl, whisk the eggs, milk, and olive oil until smooth.
- Pour the wet ingredients into the dry and fold just until no dry streaks remain.
- Fold in the squeezed zucchini, 1 cup (115 g) of the cheddar, and the green onion. Stop mixing as soon as it’s combined, the batter goes dense if you overwork it.
- Divide the batter evenly between the 12 muffin cups, filling each about three-quarters full. Top each with the remaining cheddar.
- Bake for 20 to 24 minutes, until the tops are golden, a toothpick comes out clean, and the internal temp hits 200 F / 93 C.
- Cool the muffins in the tin for 5 minutes, then transfer to a wire rack to finish cooling.
Notes
- Squeeze zucchini hard, this is the step people skip and regret.
- Fold cheese in gently to keep pockets of melted cheddar instead of a uniform mix.
- Fill muffin cups three-quarters full, gluten-free batter doesn’t rise as much as wheat batter.
- Let muffins cool 5 minutes in the tin before moving them, they’re fragile straight from the oven.
Tips for Success
- Squeeze grated zucchini in a clean towel until you get 2 to 3 tbsp of liquid out, or the crumb turns gummy.
- Use freshly shredded cheddar off a block instead of pre-shredded, so it melts into the batter instead of clumping.
- Stop stirring the second wet and dry ingredients meet, gluten-free batter turns dense fast if you overmix.
- Save some cheddar back to top the muffins before baking, so the tops get a browned, crisp cap.
- Check doneness at 20 minutes, gluten-free batters can go from soft to dry within just a few extra minutes.
Variations
- Swap in shredded Monterey Jack or pepper jack cheese for a muffin with more kick.
- Add 3 slices of chopped cooked bacon to the batter for a heartier, savory breakfast muffin.
- Stir in 1/4 cup chopped fresh dill or basil along with the cheddar for a herby version.
Storage and Reheating
Gluten-Free Zucchini Cheddar Muffins keep at room temperature for up to 2 days in an airtight container, or in the fridge for 4 to 5 days since the zucchini adds moisture that speeds up spoilage compared to a plain muffin.
Freeze fully cooled muffins in a zip-top bag for up to 3 months, the same freezer trick that keeps flaxseed banana breakfast bread moist. Thaw at room temperature for a couple hours or microwave straight from frozen.
Reheat a muffin in the microwave for 20 to 25 seconds, or in a 300 F / 150 C oven for 8 to 10 minutes if you want the cheddar top crisp again.
Serving Suggestions
A warm muffin split and buttered goes well next to a bowl of tomato soup or a plate of scrambled eggs. The cheddar edge holds up fine even after it cools, so it’s an easy lunchbox add-on.
Pack one with cherry tomatoes and grapes for a school lunch alongside cottage cheese cucumber boats, or set a basket of them out next to chili for a weekend dinner.
A little hot sauce or a smear of cream cheese on top works if you want something with more bite.
FAQ
How do I know when zucchini cheddar muffins are fully baked?
They’re done when the tops turn golden and a toothpick inserted in the center comes out clean, usually at 20 to 24 minutes at 190 C / 375 F. The internal temp should read 200 F / 93 C on an instant-read thermometer. If the middle still looks wet, give it another 2 to 3 minutes.
Can I use almond flour instead of a gluten-free flour blend?
Not as a straight swap. Almond flour has no starch or gum to hold the crumb together, so the muffins turn dense and greasy. Stick with a measure-for-measure gluten-free blend that already has xanthan gum built in, like Bob’s Red Mill 1:1, for the rise and structure this recipe is built around.
Can I freeze gluten-free zucchini cheddar muffins after baking?
Yes, they freeze well for up to 3 months in a zip-top bag once fully cooled. Thaw at room temperature for a couple hours or microwave from frozen for about 40 seconds. Reheat in a 300 F / 150 C oven for 8 to 10 minutes if you want the cheddar top crisp again.
What pairs well with zucchini cheddar muffins in a lunchbox?
A cup of tomato soup or a scrambled egg turns one muffin into a full meal. For a lunchbox, pack a muffin with cherry tomatoes and grapes, the savory cheddar flavor holds up fine at room temperature by lunchtime. They also work split and buttered alongside chili.
Are gluten-free zucchini cheddar muffins dairy-free or keto-friendly?
No to both as written, since they use cheddar and whole milk and rely on a starch-based gluten-free flour blend for carbs. Swap the milk for oat milk and skip the cheese for a dairy-free version, though the flavor changes a lot. They aren’t low-carb enough to fit a keto diet.
Do I really need to squeeze the zucchini before baking?
Yes, this is the step that saves the recipe. Grated zucchini holds a surprising amount of water, and skipping the squeeze leaves the center of the muffins gummy even after a full bake. Press it in a clean towel until you’ve wrung out 2 to 3 tbsp of liquid before folding it in.
