Here’s the thing, our weather says winter, but my recipes are screaming summer!! Or at least very late spring. I think the more and more it snows here, the more I “rebel” and want springier recipes that are fit for the nicer, warmer days I wish we were having.

Although this recipe is great for spring and summer, it does have a touch of coziness as well. I mean, it might be a zucchini lasagna, but it’s still lasagna. And there’s always something warming and hearty about a lasagna, you know?

Anyway, my point is, regardless of the weather, I’m ready for summer, and my recipes are 100% reflecting that!

The idea for this lasagna really began when I realized that after eight and a half years of creating recipes, I have yet to share a zucchini lasagna. Sure I’ve shared variations, but never just a straight-up zucchini lasagna. The kind where the noodles are replaced with thinly sliced “zucchini noodles”.

Normally, I want ALL the carbs and would never leave the pasta out of a dish. But I love zucchini and this dish has an incredible sauce and lots of cheese. It doesn’t feel like it’s missing a thing, totally flavorful and filling!

So I went to work testing out this recipe. I knew after the very first round of testing that this was going to be a recipe worth sharing.

This zucchini lasagna is SO GOOD.

Here are the lasagna details..

This recipe requires a little prep work, but it’s all easy and pretty fun too.

I like to start with the zucchini. I like to use a mix of zucchini and yellow summer squash, but using all zucchini obviously works great too.

Start out by slicing the zucchini into thin ribbons. I find this easiest to do with a mandoline, but you can use a knife as well. You’ll want to lay the zucchini flat, sprinkle it with salt, and let it sit a few minutes. Doing this will draw out any excess water and make for a richer sauce.

While the zucchini sits, make the tomato sauce. I kept this very simple, using my favorite Rao’s Homemade Marinara Sauce, fresh oregano, and thyme. I did add a special ingredient, spicy Italian chicken sausage.

Of course, if you’re vegetarian or just going for a meatless Monday theme, you can easily omit the sausage from the sauce. I’d recommend adding my homemade blend of spices. I share the spice mix ingredients in the notes section of the recipe. This will keep the sauce hearty, flavorful, and on the spicy side…even without the meat.

With or without the sausage it’s going to be great, so do what works for you!

Then just mix fresh ricotta cheese with some provolone and an egg. Layer everything up just like you would a traditional lasagna. It looks all fancy, but it’s actually the easiest to do.

Finish it off with a layer of mozzarella and bake until the cheese is melted and the sauce is bubbly.

While the lasagna bakes…make the oregano breadcrumbs!

The breadcrumbs are simply Panko and fresh oregano cooked together with olive oil until crispy. Really simple, but they add a nice crunchy, delicious topping.

While everything is baking, your kitchen will smell incredible…like an Italian grandma’s kitchen, so perfect.

  • 1. Preheat the oven to 375° F. Lightly grease a 9x13 inch baking dish.
    2 Thinly slice the zucchini to about 1/8 inch thick. Lay the zucchini flat on a clean kitchen towel and sprinkle with salt. Let site 15 minutes to draw out excess moisture, then pat dry with a towel. Try and get as much water out of the zucchini as possible.
    3. Meanwhile, heat 1 tablespoon olive oil in a large pot over high heat. When the oil shimmers, add the chicken and brown all over, about 5 minutes. Reduce the heat to low, add the bell pepper, oregano, thyme, and a pinch each of salt, pepper, and red pepper flakes. Stir in the marinara sauce, then remove from the heat.
    4. In a bowl, combine the ricotta, provolone, and egg.
    5. To assemble, spread 1/2 cup of sauce in the bottom of the baking dish. Layer over the zucchini, then dollop over 1/2 cup of the ricotta cheese, and top with about 1/2 cup mozzarella. Repeat the layering until all ingredients have been used...don't stress about making it look perfect. Top with mozzarella. Cover with foil and bake 30 minutes. Uncover, and bake another 30 minutes, until the cheese is melted and the sauce is bubbly.
    6. Meanwhile, make the breadcrumbs. Heat 1 tablespoon olive oil, the breadcrumbs, and oregano over medium heat. Cook, until the breadcrumbs are toasted all over and the oregano is fried, about 4 minutes. Season with salt.
    7. Let the lasagna sit 10-15 minutes before serving. Top with breadcrumbs and fresh basil.


Ground Italian Chicken Sausage: I buy ground chicken sausage at Whole Foods. If you can’t find it, you can use spicy Italian pork sausage, or you can make your own by adding the following spice mix to ground chicken: 1 tablespoon each of fennel seed, dried thyme, dried basil, dried oregano, salt, and pepper; 2 teaspoons each of cayenne (or less, if you don’t want it too spicy), paprika, and garlic powder; and 1 teaspoon each of smoked paprika and crushed red pepper flakes. This spice mix is great on grilled meat and vegetables, too! It’ll keep in your pantry in an airtight container for a few months.

  1. We love this recipe! It has such great flavor! We are making it for a family gathering and are going to use regular lasagna noodles as we have some picky eaters, would you recommend cooking it any differently if not using vegetables?

  2. I’ve made this several times, and it’s always been a hit! I plan on making it for company one day ahead. How you would suggest making it one day before? Should I assemble everything and juts bake the next day?


  3. Hi Tieghan,
    Will this recipe freeze ok once it is all assembled before cooking?
    I wanted to make it a few days ahead of time.
    Thanks for your amazing recipes.

    I love this recipe! I omit the meat as my daughter is a vegetarian. I typically let it sit for a bit out of the oven before cutting to let it firm up a bit. I wonder if I am not drying my zucchini out enough. It really satisfies my lasagna cravings! I portion it out and freeze it for a quick dinner when I don’t have time to cook.

    Okay guys, so I completely forgot to dry out my zucchini beforehand, so I was apprehensive about how this would turn out, but it still tasted amazing. It was just a tad bit watery, not as bad as I expected. So that shows how forgiving this recipe is lol. I can only imagine how good it’ll be if I get it right in the future.

    1. Hey there,
      Happy Sunday! I am delighted to hear that this recipe was enjoyed, thanks so much for making it! xTieghan

    Wish I’d read the comments and worked harder at drying out my zucchini! Flavours were great but waaaay too saucy. However, had I made some garlic bread on the side, I wouldn’t have minded at all. Super smart to add an egg to the ricotta, it gave a great texture.

    1. Hey there,
      Thanks so much for giving this recipe a try, sorry for your troubles with the zucchini! Let me know if you give the recipe another try! xx

    I’ve made this recipe several times. I have found that it’s best to let the zucchini sit with the salt for at least 30-45 minutes. It really draws out more of the moisture. I also do more than pat dry the zucchini. I use a lot of paper towels to soak up the moisture and wipe off the salt.

    A 28 oz. jar of marinara seems to be ample. I’ve also made it with parmesan when I didn’t have provolone on hand.

    It’s a great light version of lasagna. It’s my preferred way to make it now.

    1. Hi Deborah,
      Thanks so much for making this recipe so often and sharing what works well for you! I am so glad to hear it is always enjoyed! Have a great day! xTieghan

  8. I’m prepping meals for my maternity leave and this looks perfect! Would you recommend freezing before or after baking?

    Made this week! I wish I had left zucchini out just a little longer to get more water out BUT it was still so good! I hand sliced my zucchini slowly because I just do t care for a mandoline. Light and flavor/spice right on. Simple ingredients and no fuss—straight forward. Can’t wait to try more Teigen!

    1. Hey Miranda,
