You may have noticed, we’ve got a thing for zucchini lately.

First, there was this super quick and easy no-cook Southwestern Zucchini Noodle Bowl. Then, we used the toaster oven to broil snackable zucchini rounds and bake cheesy zucchini and lemon ricotta flatbreads.

But the zucchini love doesn’t stop there because we’ve saved THE BEST zucchini recipe for last…Cornbread Zucchini Muffins!

They’re everything you want in a good corn muffin: Lightly sweetened. Tender middles. Crispy edges.

The gorgeous bright green shredded zucchini isn’t just for looks either. It (along with a little yogurt) make the muffins moist without being soggy.

Though my favorite ingredient has to be the whole corn kernels. When you bite into one, there’s an unexpected crunch and then the kernel bursts delivering even more delicious sweet corn flavor.

Best of all, the recipe couldn’t be easier. It uses simple pantry ingredients and just ONE BOWL!

Cornbread Zucchini Muffins

Yield: 6 Muffins
Prep Time: 15 minutes
Cook Time: 15 minutes
Total Time: 30 minutes

These tender muffins have a savory-sweet flavor that tastes great paired with butter and honey or a hearty bowl of vegetarian chili.


  • 1 medium Zucchini Squash, (6 to 7-inches long, about 7 ounces or 1 cup shredded)
  • 1/2 cup Yellow Cornmeal
  • 1/2 cup White Whole Wheat Flour
  • 1 tablespoon Granulated Sugar
  • 1 teaspoon Baking Powder
  • 1/8 teaspoon Baking Soda
  • 1/2 teaspoon Salt
  • 1 large Egg, beaten
  • 1/4 cup Whole Milk
  • 1/4 cup Plain Low Fat Yogurt
  • 2 tablespoons Unsalted Butter, melted and cooled
  • 1/4 cup Canned Corn, drained


  1. Adjust the toaster oven cooking rack to the middle position and preheat to 350°F. Grease a 6-cup muffin pan with cooking spray or oil.
  2. Slice ends off the zucchini and grate using a box grater. Gather shredded zucchini in a clean kitchen towel and twist to squeeze out excess water. You should have around 1 cup of shredded zucchini.
  3. In a large bowl, whisk together the cornmeal, flour, sugar, baking powder, baking soda, and salt. Stir in the egg, milk, yogurt, and butter. Add the zucchini and corn kernels, stir just until combined.
  4. Divide batter evenly among cups in the prepared muffin pan.
  5. Bake muffins until a toothpick inserted in the center come out clean, about 14 to 15 minutes.
  6. Allow muffins to cool in the pan for 2 to 3 minutes. Remove from pan and serve warm with salted butter and strawberry preserves.


For cornbread muffins with a heartier crumb omit the yogurt.

Quick Tips

 Muffins stacked on a plate on top of a blue paisley napkin.

Tip #1: Squeezing the water out of your shredded zucchini is A MUST. Otherwise, you’ll end up with a mushy soggy mess.

Tip #2: For the lightest and most tender muffins use a plain yogurt that has some fat in it.

Batter mixed in a glass bowl with a blue rubber spatula.

Tip #3: For a denser cornbread muffin, skip the yogurt. They’ll still be tender but with a heartier crumb.

Tip #4: Don’t be worried if the batter is a little on the thick side. It’s okay, you’re making corn muffins, not cupcakes!

Tip #5: The muffins won’t be browned when they are ready. Instead look for the tops to be springy and dry to the touch. A toothpick inserted in the center of one should come out clean or with a few crumbs attached.

If you see wet batter, keep baking.

Tip #6: After the first day, store leftover muffins in the fridge or freeze them for later.

Happy Baking!


  1. I wanted to have a savory snack, so I decided to make these muffins savory. These are the changes that I made:

    – I skipped the sugar.
    – Added grated fresh ginger, grated cheddar cheese, lemon juice, a sprinkle of red chilli powder, a chia egg and a sprinkle of coriander powder.
    I poured the mixture into a mini loaf pan. I sprinkled some grated cheese on the top of the batter and baked it.

    It was very delicious. I have made this recipe many times, alternating between muffins and a mini loaf. We put a few slices in the toaster and have a delicious snack. Heavenly. I hope you don’t mind me changing your recipe.

    1. That sounds delicious, Fareeda! Especially the chili powder and cumin, and of course the cheese 🙂

      I think it’s great that you’ve made this recipe “your own” and love the idea of baking it in a mini loaf.

      Thanks so much for taking the time to comment. Happy Baking!

  2. I would like to make these for a celiac guest of ours. Can I use all cornmeal? Or would another gluten free alternative work better in this recipe? I want to serve them with the Burrito Stuffed Spaghetti Squash. (As an aside: I would add into the stuffing, Trader Joe’s “Beefless Beef”–a soy product– which would amp up the protein and make the texture more “meaty” for my meat loving guests.

    1. Hi Michelle!

      I’m thinking all cornmeal would be super grainy. We haven’t tried making this recipe with anything but the flour. You might do okay substituting a gluten-free flour blend for it? If you give it a try I’d love to hear how it goes!

      Thanks for the great suggestion on the beefless crumbles for the burrito bowls , that sounds delicious 🙂

  3. Hi Brie, I haven’t tried these yet but the recipe looks great. Thank you for a recipe with low sugar and fat, so hard to find. Looking forward to checking out your other recipes.

    1. Thanks so much Diana! It’s great to hear that not everyone is looking for keto, lol. I hope you enjoy the recipes and if you’ve got a craving for something special that you don’t see, let me know we’re always looking for recipe suggestions 🙂

      1. Hi Brie, I did make them and they were wonderful. I used the regular oven as I stretched it out to make 12 muffins (just so my husband wouldn’t eat them so quick). Very tasty and easy to do. Maybe you could add in the ingredients the 1 cup of zucchini alternative. I wasn’t going to read the instructions and was trying to figure out how much zucchini to add. You know, think we know it all and don’t need to read. Always love finding recipes that are healthier and with lower fat and sugar. Can’t wait to check out your other recipes. thanks and well done, Diana

        1. I’m so glad you enjoyed the muffins, Diana! Sounds like you nailed it and I love your idea of making the recipe as 12 smaller muffins, Tim goes through them quickly too, lol 🙂

  4. I would love to try this recipe for cornbread zucchini muffins. Since this is supposed to be a savory muffin, Is the sugar necessary?


    1. Hi Fareeda,

      If you mean baking-wise, the sugar isn’t necessary. You can leave it out and the muffins will bake up fine though they might dry out faster as sugar adds moisture to baked goods.

      Flavorwise, it depends on your preference.

      I like a little sweetness in my corn muffins. It highlights the flavors of the other ingredients and is a nice balance to the salt.

      Without the sugar, you may find the muffins a bit bland and too salty. I’d recommend trying it with the sugar first.

      Also, we have made these successfully using a sugar-replacement called Swerve. If you’re trying to avoid regular sugar you might want to check it out.

      Thanks for stopping by and happy baking!
