These Grilled Zucchini Pizza Slices have been hugely popular on the blog, and they’re perfect to make if you end up with giant zucchinis in late summer, when it gets hard to keep up with the garden. This zucchini pizza recipe can fix that pizza craving, and pizza made from zucchini and topped with pepperoni and cheese is delicious without being high in carbs.

The idea for grilled zucchini as a base for low-carb Zucchini Pizza is one of those ideas that popped into my head, and I’m not sure if I thought of it or saw it somewhere. But this recipe was the happy result when I decided to combine the ideas behind Grilled Zucchini and my sister Val’s Broiled Zucchini with Mozzarella and Pepperoni.

This is one of my Recipes for Extra Large Zucchini, and I cut slices of zucchini that were nearly 4 inches across and about 3/4 inch thick. If you don’t have a huge zucchini like that, use smaller zucchini sliced lengthwise. And if pepperoni is not your jam, use any toppings you prefer on the  grilled zucchini pizza; hope you enjoy trying it!

What other toppings can you use on zucchini pizza?

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.

How low in carbs is this Zucchini Pizza?

This tasty pizza made on slices of grilled zucchini has about 7 net carbs and 11 grams of protein in a serving of two slices.

Can you make the Grilled Zucchini Pizza without an outdoor grill?

If you don’t have an outdoor grill or it’s too cold to grill outside, you can definitely make this zucchini pizza on a Stovetop Grill Pan (affiliate link).

Will kids eat this zucchini pizza?

The zucchini pizza will be a hit with zucchini-loving adults who like pizza. I’m not sure if kids who are picky about veggies will eat this, but there are some comments on the post from people reporting that it was a hit with their kids.

How to Make Grilled Zucchini Pizza Slices:

(This is only a summary of the steps for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

1. I ‘m a fan of Rao’s Pizza Sauce (affiliate link) which only has 3 carbs in 1/4 cup, but use any sauce that’s 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.)
2. I’m a fan of making this with those overly-large zucchinis that show up in the fall. (I wouldn’t use enormous zucchinis that are mostly seeds inside.) If you don’t have a large zucchini to make round slices, cut thick lengthwise slices.
3. Cut slices of zucchini that are 3-4 inches across and 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 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.
6. 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; 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!
9. This recipe is for eight Zucchini Pizza Slices, and I am considering two slices to be a serving.
