Zucchini alla parmigiana is the perfect excuse to use up all that beautiful zucchini growing in your garden.  Strips of roasted zucchini are layered with a simple marina sauce, copious amounts of melty mozzarella and Parmigiano Reggiano cheese, and fresh basil, then baked until golden and bubbly.  And because the zucchini are roasted instead of fried, this is truly the easiest parmigiana you will ever make.

Zucchini alla parmigiana may not be as widely known as its more famous cousin, eggplant parmigiana, aka parmigiana di melanzane, but it is every bit as delicious.

In fact, some may even prefer this dish to the eggplant, since zucchini tends to have a more neutral flavor than eggplant.  

I love both dishes, but I do find that zucchini parm is somewhat easier to make.   And easier is good, especially for weeknights when everything else is not easy!

 

The secrets to my zucchini parm success

Making zucchini parm is anything but hard, but I really want to share some tips that will ensure you wind up with a top-notch dish.

Salt your zucchini

Much like eggplants, zucchini do hold quite a bit of water.  For that reason, it is important that you salt and drain the zucchini prior to roasting.

This prevents the zucchini from releasing too much liquid when it is baking with the cheese and sauce.  No one wants to eat watery zucchini parmesan.

To salt the zucchini strips, you can layer them in a colander, sprinkling a bit of salt over each layer.  Allow them to sit for 30-45 minutes, then rinse with cold water and pat until completely dry.

The secret is in the sauce

Another tip to making successful zucchini parmigiana, is to use a slightly thicker marinara sauce.  

Since the zucchini tends to release a bit of water, even in spite of the salting, it will contribute to the viscosity of the sauce.  If you start with a thin sauce, it will wind up too watery.  If you start with a thicker sauce, it will likely end up with the perfect consistency.

Patience pays off

Lastly, as with any parmigiana or lasagna, you must let the dish settle before serving.

Give it a good 20 minutes to sit after it comes out of the oven.  It will allow the ingredients to congeal a bit.  Trust me, it will be worth the wait!

How to make zucchini alla parmigiana

Each number corresponds to the numbered written steps below.

  1. Slice 5 medium-sized zucchini into 1/4″ pieces.  
  2. Layer the zucchini strips in a colander, sprinkling salt over each layer.  Set aside for 30-45 minutes.

  1. Using a cheese grater, shred the mozzarella, and grate the Parmigiano Reggiano cheese.  If you are planning to make your own marinara sauce, now would also be the perfect time to start that.  
  2. After 45 minutes or so, the zucchini should have released a lot of water, as shown in the picture above.
  3. Remove the zucchini strips and rinse with cold water to remove the salt.  Then, pat with paper towels until completely dry.  NOTE: Rinsing and drying them will not reintroduce water to the zucchini.  They will still be less waterlogged than fresh cut zucchini.
  4. Place the zucchini strips on a baking sheet lined with parchment paper.  Coat the zucchini with olive oil, and season with 1/2 teaspoon of kosher salt, and 1/2 teaspoon of black pepper.  Roast the zucchini in the oven for 25 minutes at 375f.

  1. Spoon a thick layer of marinara sauce into a 9×13 baking dish.  
  2. Place one layer of the zucchini strips on top of the sauce.   
  3. Layer the mozzarella on top of the zucchini, sprinkle some Parmigiano Reggiano on top, as well as some torn basil leaves. 
  4. Begin your next layer by spooning more marinara on top.

  1. Repeat the layering process until your baking dish is full, and bake in the oven at 375f for 20-25 minutes.
  2. After 25 minutes, if you’d like to achieve a golden top, carefully broil the zucchini alla parmigiana for 1-2 minutes, taking care to watch it the entire time to prevent burning.  Let the parmigiana settle for 20 minutes prior to serving.  Enjoy!

Zucchini alla Parmigiana

4.86 from 7 votes
Prep: 15 minutes
Cook: 45 minutes
salting time: 45 minutes
Total: 1 hour 45 minutes
Servings: 4
Layers of roasted zucchini, mozzarella, Parmigiano Reggiano, and marinara are baked until golden and bubbly.

Ingredients 

  • 5 medium zucchini sliced into 1/4" pieces
  • 4 cups marinara sauce see notes below
  • 1 pound mozzarella shredded
  • 1/2 cup Parmigiano Reggiano cheese grated
  • 1/4 cup olive oil
  • 1/2 teaspoon Kosher salt to taste
  • 1/2 teaspoon black pepper
  • 3 tablespoons fresh basil

Instructions 

  • Slice zucchini into 1/4" strips.  Layer in a colander and sprinkle salt over each layer.  Let the zucchini sit for 30- 45 minutes to release water.  Before moving on to next step rinse the zucchini to remove the salt and pat completely dry.
  • Place zucchini strips on a baking sheet (parchment paper prevents sticking).  Coat the zucchini with olive oil and season with 1/2 teaspoon of Kosher salt and a 1/2 teaspoon of black pepper.  Roast zucchini in the oven for 25 minutes at 375f.
  • Spoon a thick layer of marinara sauce into a 9 by 13 baking dish.  Place roasted zucchini strips in one layer then the mozzarella (dividing equally between layers).  Grate some Parmigiano Reggiano on top as well.  Sprinkle some torn basil leaves and finally spoon more sauce onto the layer.  Repeat process for subsequent layers.
  • Bake in the oven for 20-25 minutes at 375f until bubbly.  If you want, carefully broil the parmigiana for 1-2 final minutes to make the top golden. Watch the whole time to prevent burning!
  • Wait 20 minutes before eating to let the parmigiana settle and solidify.  Enjoy!

Notes

  • Use this marinara sauce.  Or make your own or use a store-bought version.
  • A mandoline works great to get equal thickness zucchini slices.
  • Salting helps remove a lot of excess water from the zucchini.  If in a rush you can skip this step, but the parmigiana will be much more watery.
  • Leftover zucchini parmigiana can be refrigerated for up to 3 days.  Reheat in the oven at 350f until warm or in the microwave if in a rush.
  • Freeze for up to 6 months and reheat in the oven at 350f until hot.

    Hi James- i’m making your zucchini Parmesan recipe this afternoon for my company tomorrow. I have assembled it in the 9 x 11 pan and wondered should I bake it tonight and then reheat it tomorrow for the company?
    if I do that I could cover it with foil and put it in the refrigerator, or do you recommend baking it for the first time before company comes tomorrow afternoon?

    1. Hi Mary, you can really do either way and will get similar results. Be sure to remove from the fridge about an hour before baking or rewarming. Hope you enjoy.

    Yes, I make this all the time.. can even eliminate mozzarella and just use locatelli pecorino…. bake the same way and eat it cold.. make a sandwich on Italian bread… delish.. learned this from my dad 60 years ago 😂😂😂💕🤔

    A really good recipe… longer salting definitely needed, and I think I’d make my sauce extremely thick next time. But in our house it’s a keeper! Thanks, now looking for the next thing to try!

  4. This is one of those recipes where having a food dehydrator would be really useful in evaporating a lot of the water content before using in the dish. Even placing the slices of zucchini on a rack set over a tray in a very low oven for a couple hours could help. The flavor of the zucchini could even be amplified on its own. Thanks for the recipe – zucchini is really good to eat, and here’s to hoping I can afford a larger living space for the work room.

    1. I made it with a mixture of squash and zucchini and just a pinch or two of oregano and it was fantastic.

  5. I just made this. I love zucchini. I never knew zucchini parm was a thing. Never thought of it. It came out freakin’ brilliant! Perfect! With no frying, it’s also easy as hell. Thank you sir!
    p.s. even with the salting of the zucchini, it’s amazing how much water it STILL gave off. I just drained it though. This dish is officially part of my summer rotation.

    1. Thank you! Zucchini has a massive amount of water. Letting them salt even longer will help a bit more. Glad you enjoyed it!

      1. Hi Jim..I made the zucchini dish was really salty. Is there a difference with kosher salt and regular just wondering if this caused it being too salty

        1. Hey sorry it was salty. You do need to remove the salt by rinsing it all off and then patting the zucchini dry. The same amount of kosher salt will be less salty than the same amount of table salt due to the size of the granule. But, no matter which type you use, rinsing the zucchini should remove the majority of it. You can omit the salting process for this recipe, but the issue is zucchini holds so much water that it’s best to remove some of it before cooking. Hope this helps.
