These Grilled Zucchini Pizza Slices have not only been hugely popular on the blog, but they’re perfect to make when those giant zucchinis start to show up overnight in the garden. This zucchini pizza is a great way to fight that pizza craving, and it can be loaded with pepperoni and cheese without the carbs.
The idea for grilled zucchini as a base for this Grilled Zucchini Pizza is one of those cooking ideas that just start swirling around in my head, and sometimes I’m never sure if I thought of it or saw it somewhere else. But when I decided to arrange a marriage between Grilled Zucchini and my sister Val’s Broiled Zucchini with Mozzarella and Pepperoni, I loved this result, with the offspring having some serious pizza personality.
I cut big slices of zucchini that were nearly 4 inches across and about 3/4 inch thick, but if you don’t have a huge zucchini to slice for the pizza base, use smaller zucchini sliced lengthwise. And if pepperoni is not your jam, use any toppings you prefer on the zucchini pizza you make!
What ingredients do you need for this recipe?
- large zucchini slices
- olive oil
- Rao’s Pizza Sauce (affiliate link)
- Mozzarella cheese
What other toppings can you use on zucchini pizza?
This is only a recipe in the very loosest sense of the word, because anything you like on pizza could be cooked on top of a thick slice of grilled or broiled zucchini. I’m a pepperoni girl, so of course I had to have that, but the topping options are endless here. Things like mushrooms, peppers, or sausage would need to be precooked. You could use roasted red pepper, olives, or Canadian Bacon right out of the package.
What if you don’t have an outdoor grill?
If you don’t have an outdoor grill to make the grilled zucchini pizza or it’s too cold to grill outside, you can definitely make this zucchini pizza on a Stovetop Grill Pan (affiliate link).

How to Make Grilled Zucchini Pizza:
(Scroll down for complete printable recipe.)
- I ‘m a fan of Rao’s Pizza Sauce (affiliate link) which only has 3 carbs in 1/4 cup, but I found another sauce from my neighborhood grocer that was also pretty low in sugar. You’re only using one tablespoon of sauce on each zucchini slice. (I think Basil Pesto or some type of white sauce would also taste great on this.)
- I used an over-sized 8-Ball zucchini to make my pizza the first time, but now I’m a fan of making this with those overly-large zucchinis that show up in the fall. (I wouldn’t use the enormous zucchinis that are mostly seeds inside.) If you don’t have a zucchini that can make large enough slices, I would cut it lengthwise.
- Cut slices of zucchini that are 3-4 inches across and about 3/4 inch thick, then brush both sides lightly with olive oil.
- Grill the zucchini slices on one side for about 7-8 minutes, or until there are some grill marks and the zucchini is starting to get tender. (If the slice has one side that’s larger, grill that side first so it’s the top of the pizza.) If you don’t have a grill, this could definitely be cooked under the broiler.
- I put 1 T pizza sauce on the top of each zucchini slice, but you might want a tiny bit more, depend on how big your slices of zucchini are. You can heat the sauce if you’d like, but next time I wouldn’t bother.
- Then put other toppings as desired on top of the sauce. I added one tablespoon of Mozzarella cheese, about 4 slices of pepperoni, and then a slight sprinkle of additional cheese. (You can see there was no food stylist for this shot. Sorry about the messy photo, but you get the idea.)
- Then put the topped pizzas back on the grill (or under the broiler) and cook for 7-8 minutes more (or probably less time for broiling.)
- Remove pizza from the grill and serve hot!
- These photos show four pizzas that I made to take photos, but the recipe is for eight Zucchini Pizza Slices. I am considering two slices to be a serving.
The zucchini pizza will be a hit with zucchini-loving adults who like pizza. I’m not sure if kids who were real picky about veggies would eat this, but I’m guessing quite some kids will like it.

Grilled Zucchini Pizza Slices
Grilled Zucchini Pizza Slices are a healthier way to satisfy that pizza craving, and this zucchini pizza is perfect to make with overly-large zucchini that shows up in the fall.
- 8 large round zucchini slices (about 3-4 inches across and 3/4 inch thick)
- 3 T olive oil
- 8 T Rao's Pizza Sauce
- 12 T grated Mozzarella cheese
- 32 slices pepperoni (see notes)
- Oil the grill grates (I use a bit of oil on a paper towel), then preheat grill to medium-high.
- Cut a large zucchini into thick slices about 3/4 inch thick. (I first used 8-Ball zucchini, which made lovely round slices, but now I've made this many times with large late-season zucchini that makes slices about 4 inches across. If you don't have a zucchini that makes large round slices, you can cut the zucchini into lengthwise slices. I wouldn’t use enormous zucchini with large seeds for this recipe.)
- Grill the zucchini slices 7 minutes total, or until there are some grill marks on the bottom side and it’s starting to be tender. (The second side will get cooked after you add the toppings.)
- If the zucchini has a side that’s slightly larger, grill that first so it will be the “top.”
- If desired, you can heat the sauce while the zucchini grills. (I did, but next time I wouldn't bother.)
- Remove zucchini from the grill, putting them grilled-side up on a cutting board you can use to take them to the kitchen.
- Add 1 tablespoon sauce to each zucchini slices.
- Then top with one tablespoon Mozzarella cheese cheese
- Put 4 slices pepperoni over the cheese (or other toppings as desired.)
- Put a tiny bit more cheese over the pepperoni.
- Put loaded zucchini slices back on the grill and cook 7 minutes on the second side with the grill lid closed. (Check them every few minutes to see when the cheese is melted and the toppings are lightly browned.)
- Remove zucchini pizzas from grill and serve hot.
- I doubt this would reheat that well, but if anyone has leftovers and tries reheating it I’d love to hear how it works.
You can use any pizza toppings of your choice. I love pepperoni, but you can also use sauteed mushrooms, Canadian bacon, cooked sausage, caramelized onions, sliced olives, anchovies, sauteed bell peppers, or any other toppings you’d enjoy on pizza.
I thought about using grilled zucchini as a base for pizza for a while, and this recipe was the happy result.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Using grilled zucchini instead of a crust makes Grilled Zucchini Pizza Slices a low-carb pizza option, and this should work for low-carb and Keto diets, especially with full-fat cheese and pepperoni. You need to use toppings that aren’t too high in fat if you’re making this for the original South Beach Diet.

Julia Child does a similar “pizza” with eggplant so I figured someone would have tried it with zucchini and found your zucchini recipe. I was so glad to know I could do something with the huge zucchini my neighbour gave me without taking out the seeds. I did half with salmon and smoked gouda cheese, and half with pepperoni and parmesan. I bbq’d it for longer than 6 minutes but it was a lovely light dinner. I wont ever be picking out the seeds again. Thank you for posting your ideas and recipes
Glad you liked it! I do have a recipe on the site for Julia Child’s Eggplant Pizza too if you use the search bar (slightly adapted from her recipe.)
These are so good! Honestly they cured my pizza cravings!
Yaay, so glad you enjoyed them!
I make these as a quick lunch all the time. I skip the grill though and use my air fryer for them. Just layer the sauce, cheese and toppings and air fry for 6-10 min depending on how brown you like your cheese. Delicious! Easy peasy.
So brilliant, I MUST try this in the air fryer! Thanks for sharing that!

Absolutely NO NEED to leave a rude comment if a recipe doesn't appeal to you. Just move on to the next blog.
Thanks for the recipe! Made this and blogged about it here:
So glad you enjoyed the recipe!
June Baby, hope you enjoy!
Those look fabulous! Such a great way to use zucchini, and tasty looking too! 🙂
Soccer Mom, so glad most of you enjoyed it. And not a surprise that those who don't like zucchini won't be fans of this.
I made this last night with the abundance of zucchini I had from my garden! Results? 4 out of 6 loved them! My husband and I, my 22 year old daughter, and my 18 month old grandson all thought they were delicious. My 19 year old ate 1, then joined her 14 year old sister (who wouldn't even try it) in making bagel pizzas. I used sharp cheddar cheese on half of them and mozzarella on the other half. Both were delicious! Will make it again (and provide an alternative for those who don't care for that much zucchini!)
Shari my goal is to make it lower in carbs, so potatoes won't work for that. But if you don't care about that it might taste good.
What an amazing idea! I bet you can make this on potato slices, as well.
Alicia, seems obvious to me that if you don't like zucchini you're not going to like this. Sorry you were disappointed.
