How did a reader improve the Parmesan Encrusted Zucchini?

This zucchini parmesan recipe originally came from Vegetables Every Day by Jack Bishop (affiliate link), a very old book that I still use to look for ideas for cooking vegetables. But my preferred version of the recipe and the one I’m sharing here is actually simpler than the one in the cookbook, because years ago a reader told me they cooked the zucchini completely under the broiler, and that’s the way I’ve been doing it ever since.

What kind of Parmesan should you use for Parmesan Crusted Zucchini ?

Of course freshly-grated Parmesan would be great for this recipe. But if you don’t have a block of Parmigiano Reggiano, this recipe will work perfectly well with the coarsely-grated Parmesan that’s widely available. I wouldn’t use the finely grated Parmesan in the green jar for this; that won’t melt and cover the zucchini in the way that makes this parmesan crusted zucchini recipe so good!

How to make Parmesan Crusted Zucchini:

(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. Trim the ends and cut each zucchini in quarters lengthwise, cut into strips about 3 inches long and then cut away the inner seedy part of each piece. 
  2. Cover baking sheet with foil and lay the zucchini on the baking sheet in rows.
  3. Then brush or mist the zucchini with a tiny bit of olive oil (I used my Misto Olive Oil Sprayer (affiliate link) and sprinkle with Italian Herb Seasoning (affiliate link) or your favorite seasoning.
  4. Put in a pre-heated broiler for 6-8 minutes, or until the zucchini is starting to get barely tender. (Remember the zucchini will cook longer when you’re melting the cheese.)
  5. While the zucchini cooks, melt the butter (or use a combination of butter and olive oil, or all olive oil) and measure about 3/4 cup of Parmesan cheese. (I recommend coarsely grated Parmesan that comes in a plastic jar or grate it yourself, but powdery pre-grated Parmesan won’t work well for this.)
  6. When zucchini is nearly as tender as you’d like it, remove from oven, brush with butter, sprinkle the zucchini generously with Parmesan, and put back under the broiler for 4-5 minutes, or until it’s melted and starting to brown. Watch carefully towards the end!
  7. Serve hot and wait for compliments! And there will not be leftovers!

Low-Carb and Gluten-Free Parmesan Crusted Zucchini is the perfect way to cook zucchini and this is an extra-easy recipe the whole family will love! In fact, I bet this zucchini plus parmesan recipe is something you'll make over and over during zucchini season.


  • 4 medium zucchini
  • 1 T olive oil, for misting zucchini
  • 1 tsp. Italian Herb Blend (or your favorite seasoning blend)
  • 1/4 C butter, melted (see notes)
  • 3/4 cup coarsely grated Parmesan cheese (more or less to taste)


  1. Preheat the broiler and adjust the rack so your pan will be about 6 inches away from the heat.
  2. Cover a large baking sheet with foil (or spray with non-stick spray if you prefer).
  3. Wash zucchini skins and pat dry, cut off stem and blossom end of each zucchini, and cut zucchini into four lengthwise strips and cut the zucchini pieces into strips about 3 inches long. Then cut away the inner seedy part of each piece.
  4. Arrange zucchini on broiler pan in rows, close together, skin side down.
  5. Mist or brush the zucchini with olive oil and season the zucchini with the Italian Herb Seasoning (affiliate link) or your favorite seasoning blend.
  6. Broil zucchini about 6-8 minutes, or until it’s starting to feel barely tender when you pierce it with a fork.  (If your broiler is powerful I’d start checking after about 4-5 minutes.  Remember the zucchini will cook more when you melt the cheese.)
  7. When the zucchini is barely tender, remove the pan from under the broiler, brush zucchini with melted butter (or whatever combination of butter and olive oil you’re using), and sprinkle Parmesan cheese over the zucchini, trying to get most of the zucchini covered.
  8. Put zucchini under broiler and cook until cheese is completely melted and well-browned, about 4-5 minutes, or a little more or less, depending on how hot your broiler is and how close the pan is to the heat source.
  9. Serve hot or warm. There won’t be any leftovers, so you don’t need to worry about whether this will keep in the refrigerator.


You can use a combination of butter and olive oil or all olive oil for brushing the zucchini if you prefer, but the butter adds a nice flavor.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
This Parmesan Crusted Zucchini is a great recipe for low-carb and Keto eating plans. It would probably be considered a “once in a while treat” for any phase of the original South Beach Diet, due to the amount of saturated fat in the cheese (and butter if you’re using it), although zucchini is very low in calories, carbs, and fat.
