These Grilled Zucchini Pizza Slices have not only been hugely popular on the blog, but they’re perfect to make this time of year when those giant zucchinis seem to spring up overnight in the garden.  If you don’t have a huge zucchini to slice for the pizza base, use smaller zucchini sliced lengthwise.  This is a great way to fight that pizza craving, and it’s a pretty diet-friendly recipe for a dish that’s loaded with pepperoni and cheese. Use low-fat pepperoni if you prefer, or for Keto, use any pepperoni you wish!

The idea for grilled zucchini used as a base for pizza toppings in these Grilled Zucchini Pizza Slices is one of those cooking ideas that swirl around in my head, and sometimes I’m never sure if I thought of it or saw it somewhere else. I kept wondering how it would work to arrange a marriage between Grilled Zucchini and Val’s Kid-Friendly Broiled Zucchini Rounds with Mozzarella and Pepperoni, with the offspring having a little pizza personality, and when I saw Alea’s Eggplant Pizza Bites on $5 Dinners, it convinced me to try it.

Even so, 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. Admittedly, this is not a pizza in the truest sense of the word, but if you’d like pizza flavors with a “crust” that’s gluten-free, low-glycemic, and low-carb, this is an idea you may end up liking just as much as I did!

How to Make Grilled Zucchini Pizza Slices:

(Scroll down for complete printable recipe.)

  1. I used an over-sized 8-Ball zucchini to make my pizza, but any large zucchini could be used here. You may want to slice it lengthwise if it’s a long zucchini. (I wouldn’t use the enormous zucchinis that are mostly seeds inside.)
  2. I ‘m a fan of Rao’s Pizza Sauce (affiliate link) which only has 3 carbs in 1/4 cup, but I didn’t want to drive to Whole Foods, and the sauce from my neighborhood grocer was also pretty low in sugar.
  3. Cut slices of zucchini about 3/4 inch thick, then brush both sides lightly with olive oil.
  4. 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.
  5. I put about 1 T pizza sauce on the top of each zucchini slice, but the amount will depend on how big your slices of zucchini are. You can heat the sauce if you’d like, but next time I might not bother. (I think Basil Pesto or some type of white sauce would also taste great on this.)
  6. Then put other toppings as desired on top of the sauce. I added a pinch of Mozzarella cheese, a few 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.)
  7. 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.)
  8. Remove pizza from the grill and serve hot!

This 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 a few kids would like it.

Grilled Zucchini Pizza Slices

Grilled Zucchini Pizza Slices are a healthier option that just might satisfy that pizza craving.


  • large zucchini slices, cut 3/4 inch thick (see recipe directions)
  • olive oil, for lightly brushing both sides of pizza and oiling grill grate
  • pizza sauce of your choice (I used canned red sauce, but you could also use Basil Pesto or white sauce. Extra sauce can be frozen for later. Look for a sauce that’s low in carbs, without added sugar.)
  • grated Mozzarella cheese (you can use any cheese you’d enjoy on pizza.
  • pizza toppings of your choice (I used 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 like on pizza.)


  1. Oil the grill grates (I use a bit of oil on a paper towel), then preheat grill to medium-high. (If using a broiler, it should be reheated as well.)
  2. Cut zucchini into thick slices about 3/4 inch thick. (I used 8-Ball zucchini, which made lovely round slices, but you can cut the zucchini into round slices or lengthwise slices, depending on what shape the zucchini is. I wouldn’t use enormous zucchini with large seeds for this recipe.)
  3. Grill the zucchini 7-8 minutes, or until there are some grill marks and it’s starting to be tender.
  4. If the zucchini has a side that’s slightly larger, grill that first so it will be the “top.”
  5. If desired, you can heat the sauce while the zucchini grills. (I did, but next time I might not bother.)
  6. Remove zucchini from the grill, putting them grilled-side up on a cutting board you can use to take them to the kitchen.
  7. Add sauce, cheese, and other toppings as desired. (I spread each slice of zucchini with about 1 T red pizza sauce, then sprinkled each piece with a generous pinch of cheese, added 4-5 slices of  pepperoni, and sprinkled over a tiny bit more cheese.)
  8. Put loaded zucchini slices back on the grill and cook 7-8 minutes more with the grill lid closed. (Check them every few minutes to see when the cheese is melted and the toppings are lightly browned, especially if you’re using a broiler. If you have a gas grill where you can regulate the heat, I turned it to high when I put the pizza back on.)
  9. 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.)


This “recipe” is just a guideline, adjust amounts to make as many pizzas as you’d like.

I thought about using grilled zucchini as a base for pizza for a while, but Alea’s Eggplant Pizza Bites at $5 Dinners were what motivated me to try it.

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, but you still need to use toppings that aren’t too high in fat if you’re making this for the South Beach Diet. (I talk more about reduced-fat pizza toppings in the recipe for South Beach Diet Friendly Flatbread Pizza.)  For other low-carb diets, this would be a great choice, and most low-carb diets would prefer full-fat cheese and pepperoni.

  2. Great idea! They look sooo tasty too!

  3. Barbara, we will meet someday, I just know it. I really want to come to Australia.

    Joanne, it did the trick for me. I especially like using turkey pepperoni in this (love the turkey pepperoni!)

    Saee, they would be snack sized if you sliced a long zucchini into rounds. Mine were about the size of a piece of bread.

    Susan, thanks!

  4. They look perfect! They'd make great appetizers or cocktail snacks!

  5. Healthiest pizza slices ever! These are so cute and would work so well to satisfy pizza cravings without breaking the calorie bank. Love it.

  10. WC, thanks (I know just what you mean; I feel that way all the time when I see things people have come up with!)

    Princess Aioli, I'm having a hard time imagining this with acorn squash, since you can't eat the skin, but yellow squash and other types of summer squash would work for sure.

  11. What a smart idea! Do you think any other squash would work? Acorn squash came to mind…

  12. I love this idea. It's one of those perfectly simple dishes that make me wonder why I never thought of that.

  13. Thanks Dara! The new grill gets so hot, it makes good grill marks. I hope your kids like it if you try it.

  14. What a fun idea! I think that these would get my kids excited about zucchini. Those grill marks are perfect.

  15. Thanks Bron. I am enjoying the cooler weather here, but not ready for winter! Hope the girls like the zucchini pizza!

  16. Awesome Kalyn, they almost make me look forward to my zucchini glut 😉
    We're soooo ready for summer down here, let me tell you!
    My girls will love these, such a fantastic idea.

  17. Lydia, it was a good way to use those 8-Ball zucchinis that got a big larger than I wanted!

    Thanks Beth, it satisfied my pizza craving very well!

  18. Those are so cute!! What a fantastic idea 😀

  19. Those are absolutely adorable, and perfect for the eight ball zucchini. I'd substitute mushrooms for the pepperoni to make my own favorite "pizza" topping.
