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!

Spicy Zucchini Ricotta Lasagna with Oregano Breadcrumbs |

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. Made this tonight and it was WONDERFUL. My husband ate an embarrassing amount! Lol we will be making this again in the future! I’ve made zucchini lasagna many times and this is by far my favorite!

  2. 5 stars
    Incredible recipe! I made a few edits on the recipe to better suit a keto friendly meal – and what I had in the freezer. I did 1/2 lb ground venison and 1/2 lb spicy Italian pork sausage. Also omitted the red bell pepper and breadcrumbs but added the extra shredded provolone & some parm on top. Didn’t miss the pasta (and the bloat from pasta) one bit and enjoyed every bite! Thank you for the recipe!

    I’ve made this recipe three times now because my family and extended family loves it so much. It just gets better every time! 🙂

  4. Oh my this is SO good, and that’s coming from a self-avowed hater of all things zucchini/squash. My wife cut the sauce amount to about a third and completely eliminated the breadcrumbs, making this keto-friendly delicacy even more so. She also used ground turkey instead of chicken, as we prefer the taste of the former.

    So, using the ingredient listings of each item that went into the recipe, I calculated a 1/8th serving to be only 210 calories. That’s quite a bit different than the listed 382, even accounting for the reduced/eliminated ingredients already mentioned, so I may have to go back and check my math. But, if it’s correct, the carbs are only 4.2 grams (2g of sugar), with 12.6g of fat and 19.1g of protein.

    It also warms up very nicely too.

    THANK YOU for this fantastic recipe, it is a godsend for pasta lovers who are going the keto diet route.

    Finally got to make this one last night! Had to make a couple of cheese substitutions because my boyfriend doesn’t like ricotta (crazy I know) but it turned out amazing! I was extra cautious, drying the zucchini for a lot longer than the recipe said to and I’m glad I did. Was my first time using zucchini as a noodle alternative and we truly couldn’t stop eating this last night, very happy with it!

  6. I’m making this for a dinner party tonight! Quick question: when adding the spice mix to ground chicken, are you recommending adding the entire amount? Seems like a lot of spice for one lb of chicken! 🙂

    1. Hey there,
      Yes, I would use what the recipe calls for. I hope you love the dish, please let me know if you give it a try! xTieghan

    This was absolutely delicious!!! I will definitely be making it again soon. I was worried that it would get watery because of the zucchini, but I was careful to dry the zucchini out really well and had no issues. I used spicy italian pork and that worked perfectly. 10/10 recommend!

    Don’t leave out the breadcrumbs! Yum! I needed to dry out the squash and zucchini a bit more but as there was a little extra water otherwise turned out great 😊

    This recipe is soooo good! I used Italian sausage instead of chicken sausage just because that’s what I had on hand, but didn’t change anything else and it was absolutely delicious! My husband isn’t big on vegetables and even he couldn’t stop raving about it.

    This was delicious and so easy! I just sprinkled panko breadcrumbs on top as I didn’t have time to do the toasting with the oregano. I used ground chicken and it had great flavor. My kids loved it! I am loving all your recipes!

  12. I made the vegeterian version tonight and it was absolutely delicious! Loved the spice mix in the note. This is now one of our recipes and can’t wait to have again.

    This was really delicious and luxurious. And, unlike most lasagna-style recipes, the proportions worked out well (not too little/too much of one type of layering ingredient). I used the spice blend in the note for plain ground chicken (mixed recipe and used three teaspoons) and it was great. Thank you!

    1. Hey Andi,
      Wonderful! Thanks so much for making this dish, I am so glad to hear that it was enjoyed!! xTieghan

    This recipe was just as amazing as all the other ones I have tried! I used ground turkey and seasoned it like I would the chicken. It tasted just like Italian sausage and was so good. You’re right it made my whole house smell so good and I didn’t mind not having the noodles one bit. I never put egg in my ricotta cheese before and made it tastier than it already it to begin with. Will definitely make this again!
