It’s no secret that I am a big fan of anything that has to do with pasta, luscious red sauce, and CHEESE. I’m obsessed with Italian food, but I try to keep it balanced because Italian cuisine tends to be higher in carbs.

This week we enjoyed this delicious and savory lasagna made with zucchini noodles. Yes, I said zucchini. As in, no pasta noodles – just layers of sliced veggies, fresh basil, rich tomato sauce, and so.much.cheese!

Lower in carbs but still has all the cozy, cheesy lasagna feels. This recipe is soo delicious and satisfying that you won’t even miss using pasta! 

Ingredients Needed

You’ll need just a handful of Italian cheeses, fresh produce, and fresh herbs to make this recipe. Here’s the full list: Zucchini (yellow or green), Parmigiano Reggiano (fresh parmesan), mozzarella (low moisture), ricotta, garlic cloves, egg, fresh basil, fresh oregano, and marinara sauce.

Let’s Make Zucchini Lasagna – step by step

How to Make Zucchini Noodles Less Watery (3 steps)

  • Thinly slice zucchinis: Use a mandoline slicer, vegetable peeler, or carefully use a chef knife to slice zucchini into 1/8 inch thick slices. Thicker cuts will have more moisture and be difficult to dry out completely.
  • Sweat noodles: Lay noodles on paper towels and salt on both sides. Let “sweat” excess moisture for 10 minutes, then pat dry.
  • Pre-bake zucchini noodles: the final step in ensuring you get as much moisture out as possible is pre-baking the noodles before layering. Lay them on a sheet pan lined with parchment paper and bake for 10 minutes at 375F. Dry excess moisture with paper towels after baking.

Mix together ricotta filling ingredients in a bowl.

Then in the baking dish layer lasagna: a thin layer of marinara sauce, zucchini noodles, a thin layer of ricotta filling, marinara, mozzarella, parmesan cheese, and fresh basil & fresh oregano. Repeat until finished.

  • Top lasagna with sauce, mozzarella, and parmesan cheese. Bake uncovered at 375F for 40-45 minutes then broil for 1-2 minutes to brown cheese. 

How to Reheat

If refrigerated or frozen, the lasagna can be easily reheated.

For refrigerated lasagna: preheat oven to 350F and reheat for around 15 minutes until warm.
For frozen lasagna that is unbaked: let thaw and bake at 350F for 30 to 40 minutes until cheese is browned and bubbling. 

Tips For Success

Tip

Slice Vegetables Like a Pro

Mandoline Slicer

I love using this mandoline slicer to get consistent cuts of zucchini for this recipe – it makes my life so much easier! It's a safe and efficient way to slice all types of vegetables. A must-have for your kitchen.

  • Slice zucchini noodles: Use a mandoline slicer to get precise, thin noodle cuts with the zucchini. If you are experienced with a chef’s knife and feel comfortable, you can slice the zucchini noodles with a knife. Please be very careful doing this step. 
  • Use our favorite marinara (homemade or store-bought): For this recipe, you can use my family’s San Marzano Tomato Sauce or my family’s favorite store-bought marinara!
  • Tips for fresh flavor: I think fresh herbs make all the difference! I love layering lasagna with lots of chopped fresh basil and even fresh oregano too. Keep in mind, dried herbs do not give as much flavor as fresh herbs.
  • Don’t love ricotta? Ricotta can be a bit heavy and I know not everyone loves it. You can completely remove the ricotta filling from this recipe and layer with parmesan, mozzarella, marinara, and lots of fresh basil. It tastes just as delicious and is a little less heavy!

Serving Suggestions

We love serving this healthy lasagna with some chickpea pasta or gluten-free pasta noodles! If you’re looking for a veggie-forward side dish, you can also pair it with this Italian salad or our Tuscan artichoke salad. And a side of crusty french bread or sourdough for sauce dipping is always a must!

Ingredients

  • 4-5 medium-large zucchinis, sliced thin (1/8-inch cuts)
  • 1/2 cup parmesan cheese
  • 3 cups mozzarella, shredded
  • 3 cups tomato sauce
  • 2 teaspoon fresh oregano
  • 3 Tablespoons fresh basil

Ricotta filling

  • 3 garlic cloves, minced
  • 1 1/2 cups ricotta cheese (drained of liquids)
  • 1/4 cups parmesan cheese
  • 1 egg
  • pinch of salt
  • 1/4 teaspoon black pepper
  • 1/4 cup fresh basil, chopped (for dried basil use 2 Tablespoons)

Instructions

  1. Preheat oven to 375F.  

  2. Salt & pre-bake zucchini noodles: arrange zucchini slices on sheet pan lined with parchment paper. Sprinkle with course sea salt – let sit for 5-10 minutes so zucchini "sweats" any excess moisture. Use paper towels to press and dry zucchini noodles. Then bake noodles for 8-10 minutes – pat them dry when finished baking. Note: pre-baking the zucchini will help dry up even more moisture from the noodles.

  3. Ricotta filling: in a medium-sized bowl, mix all of ricotta filling ingredients together.

  4. Layer ingredients: In a 13×9 baking dish, layer lasagna: spread a thin layer of sauce on the bottom of the dish, add layer of cooked zucchini noodles, thin layer of ricotta filling, and mozzarella cheese & little parmesan, and generous sprinkle of freshly cut oregano & basil. Repeat each step until finished. On top layer with sauce, mozzarella cheese, and parmesan cheese. 

  5. Bake: Leave dish uncovered and bake for 40-45 minutes, then broil on HIGH for 1 to 2 minutes until cheese is browned. Sprinkle with chopped fresh basil. Slice and enjoy! 

Notes

Tips for properly cutting zucchini into noodles (two ways)

Use a mandoline slicer: mandoline slicer is a great option to get precise vegetables cut without using a chef knife.

Cut with a chef knife: If you are experienced with a chef’s knife and feel comfortable, you can slice the zucchini noodles with a sharp knife. Remove the top and bottom stems of the zucchini, stand upright and carefully slice from top to bottom into 1/4-inch thick slices. Please be very careful doing this step.

      Zucchini Lasagna
      I just started cooking with Zucchini, this month. I love this receipe! It’s my “goto dish”, anytime! I have made it twice. Once with turkey meat and once without it. Both dishes were delicious! I do have pictures. How do I share them.
      But, I am still not sure how to season the Zucchini. So, thank you.

      I made this for dinner last night. It was really good. No water from zucchini which was great. A little time consuming but with practice it might go faster.

    This recipe for zucchini lasagne is so yummy…a few notes for the next time I make it is to be sure to use a mandolin to slice the zucchini because some of my slices were a little on thicker side and needed more than 40 minutes to bake. I also would be sure to remove as much moisture from the zucchini’s prior because they do release a lot of moisture into the dish while baking. I also used a blend of Parmesan cheese and mozzarella which worked really well! Definitely would make again! Makes a great side dish if you’re vegetarian based or for your next gathering!

    • Awww so glad you liked it! And agreed. The sizing of zucchini thickness matters to help moisture release properly. 🙂 Thanks so much for your feedback!

  • Avatar for aas aas says:

    Hi I haven’t made this but I have a question. When you salt the zucchini and leave it for 10 minutes, do you just pat it dry and let the salt stay on the zucchini slices? Wouldn’t that make the dish overly salty?

    • You’ll only need to sprinkle a little salt over – and yes, by pressing the moisture out you absorb quite a bit of the salt. Results shouldn’t be salty 🙂

    Ok I made this for my mother in laws birthday. I did it my way along with the recipe. I used half noodles half zucchini. I made the sauce like was stated adding half hamburger half Italian sausage. It was such a huge huge hit, I have been requested to make it again. Thank you.

    Well I don’t have any eggs at the moment. is there anything I could sub?

    • The egg is just the binder, feel free to try it without it! 🙂 The ricotta may be a little harder to spread but it shouldn’t make a huge difference.

  • So sorry to hear that, Virginia! Sometimes they can have extra moisture.

    I made this last night. It came out really watery. I took as much moisture out of the zucchini as I could get. However, the flavor was great! I will make it and try draining the ricotta to see if that helps as far as it being watery…Thanks so much for the recipe!

    • Great idea with draining the ricotta! I will have to try that as well 🙂 Thanks sue!

    • Avatar for LISA LISA says:

      Sue, mine came out a little watery but I took some paper towel and soaked it up and then after chilling leftovers I cut into serving sizes and froze them so when I want it I just have to thaw it out and I usually microwave it.

  • I’m so sorry to hear that. Would love to hear what went wrong so I can maybe help!

    This was delicious! I added ground turkey to the sauce.

  • Avatar for Stacey Stacey says:

    Yum!! My boyfriend and I both thought this dish was delicious! Salted the zucchini leaving it to sit for about an hour before squeezing as much liquid out best I could, found I didn’t have too much of an issue with liquid especially after leaving it to sit for about 10 mins before serving. Added steamed sliced pumpkin as an additional layer, great addition of flavour. The fresh basil is a must! Thanks for a great recipe, will definitely make again.

    Absolutely delicious and a keeper. I changed it a bit according to what I had, so I used cream cheese instead of ricotta and also added meat, onions and garlic to the tomato sauce. Thank you.

  • Avatar for Sylvia Sylvia says:

    Delicious! I used chicken sausage which added a lot of flavor.

  • Avatar for Lisa Lisa says:

    What a disaster, a watery soupy mess even after using your advice to dry out the zucchini. Flavor was not bad but it was a mess, I won’t bother trying this one again.

    • I’m so sorry to hear that. Zucchini’s have lots of moisture, so they can be tricky. Even my lasagna’s vary in excess moisture, but I work with it. You can also bake them for 10 minutes after salting and patting dry to really make them work!

    • Avatar for Dawn Dawn says:

      Try putting the zucchini in the oven for a bit first to dry it out

    I made this tonight for dinner. It was DELICIOUS! I did make a couple of amendments. First, I added a huge pack of sliced mushrooms I got at Sam’s Club by cooking them and then adding a mushroom layer after each parmesan cheese layer. I ended up with three layers of mushrooms (the last layer being on top). The second thing that I did differently was used Great Value (Walmart brand) tomato, garlic, and basil pasta sauce because I didn’t have any tomato sauce on hand. It was so filling and I am definitely added this to my low-carb, but not keto meal plan.

    This is ABSOLUTELY FANTASTIC and DELICIOUS!!! I’ve made this twice now, and I can’t get enough of it! I use Rao’s jar marinara sauce, and that truly adds to the flavor. It tastes just like regular lasagna, minus the carbs.

    It’s a bit time consuming to prep, but oh-so-worth it in the end…😊Thanks for a fabulous recipe, it’s a keeper!!!!

    First, we liked this. We aren’t zucchini fans, so when they showed up in our produce box last week, I began my search to disguise them. This did that very well. A couple things I did differently…I don’t have a mandolin and chose t slice by hand. I did NOT slice vertically, though. I sliced one side off and then put the flat side down on the cutting board and sliced the rest. I also opted to mix my fresh herbs into the ricotta mixture instead of using them as a separate layer. Should I receive zucchini again, this will be a contender.

    • Thanks so much Kristen! I’m glad the slicing could work out the other way. AND that you guys could enjoy zucchini despite not being fans of it! 🙂

    This was absolutely delicious! I halfed the recipe ( only two of us) and added ground beef to my homemade marinara. I subbed cottage cheese for ricotta because I had that on hand. The flavors were devine!

  • Avatar for Laura Laura says:

    This recipe is excellent! I made it with our own garden produce and the fresh flavors just popped. Did not miss pasta at all. One thing I did add was mushrooms which I think helped to carry the flavors.

    I make a version much like this – I saute my zucchini after salting, but before putting in the pan to bake. I’ve never had watery zucchini (but this is very time consuming). I’m going to try baking it first. Just curious. Have you ever tried baking the noodles, then freezing (after sweating them of course). It would speed up making the meal ….

    • Avatar for Bethany Bethany says:

      Hi Mel, I’ve not tried freezing them after baking but you certainly can try that! Let me know if you do. I hope you enjoy the recipe!

  • Avatar for MowJoe MowJoe says:

    well, just placed in the oven. I did pre bake and waiting on results.
    Had some mushrooms that needed to be use so sautéed them and added some sliced roasted potatoes, may as well as use what’s in the fridg; makes me feel good 🙂 Did not use the ricotta cheese as thought it was to be too heavy like the recipe suggested

    • Avatar for Bethany Bethany says:

      So glad you were able to make some adjustments! I make my veggie lasagna and regular lasagna without ricotta nowadays and love it 🙂

    This came out good! Glad I soaked up as much liquid as possible from the zucchini before and after pre-baking. The herbs added a lot.
