Zucchini Lasagna

Zucchini lasagna is a fresh take on a classic comfort food dish. It’s loaded with veggies, but still has the rich flavors and scrumptious texture of a traditional lasagna. Top it off with some grated parmesan cheese and basil leaves, and you’ll have the perfect weeknight meal for the whole family.

When it comes to making weeknight meals a little easier, casseroles can’t be beat. You may have already tried my Whole 30 Chicken Broccoli Casserole or Healthy Breakfast Casserole. But you can never go wrong with a good ol’ lasagna right? Especially a healthy one.

So with several zucchinis left in my fridge I thought, why not make a zucchini lasagna! Not only is this version gluten-free, low-carb, keto-friendly and packed with vegetables, but it’s still got that hearty, cheesy lasagna flavor. Albeit a little lighter and healthier (which is a definite win).

How To Cut Zucchini For Lasagna

You can use a mandoline, peeler or vegetable sheet cutter. But because many people don’t own a vegetable sheet cutter, I’m showing you how to cut your zucchini using a mandolin or a peeler today.

I prefer a mandolin because it allows me to control the thickness of my zucchini and I find it to be faster and easier than a peeler. But it’s up to you.

How To Make Zucchini Lasagna Less Watery

You may recall from my zucchini noodles post that zucchini is 95% water. That means when you cook it, it will naturally become watery. But if you’re looking to have a little less juice in your lasagna, I do have a few tips:

  • Slice your zucchini into thinner slices: thinner slices mean less zucchini, thus less water.
  • Salt your zucchini and let it sit for 15 minutes: salt draws the water out of the zucchini. Then, just blot it dry with a paper towel.
  • Grill it to reduce the moisture: grill the zucchini for 1-2 minutes on each side.

Personally, I don’t mind if my zucchini is a bit more watery. I just scoop it out with a spatula that has holes to allow any water to drain. But feel free to use the method that works best for you.

Lastly, note that this recipe also uses more zucchini than other zucchini lasagnas, as the slices are layered on top of each other. So it will come out a bit more watery than expected. I personally love biting into the chunks of zucchini, so my motto is the more the better!

What Other Veggies Can You Use In Lasagna?

The beauty of a lasagna is that you can pack it with any thin vegetables. Vegetables such as mushrooms, spinach, onions, or eggplant can be easily added as a layer. Or you can slice pumpkin or sweet potato into alternating slices with the zucchini. The possibilities are endless.

Zucchini Lasagna Ingredients

The ingredients for zucchini lasagna are pretty basic: zucchini, ground beef, pasta sauce, ricotta, parmesan, mozzarella, egg, basil and parsley. But there are a few small details to watch out for when it comes to the texture and consistency. Let’s take a look:

  • Small vs. large zucchini: Either size will work. Just make sure you have about 2 pounds of zucchini which is about 5 small zucchinis or 3 large zucchinis.
  • Part skim vs. whole milk ricotta: Whole milk ricotta has a richer, creamier texture while part skim will save you some calories and fat. Both work great, it’s up to you.
  • Mozzarella vs. parmesan: I suggest to use both! In this recipe I mix the ricotta and parmesan together and grate the mozzarella on top. I love the variety of cheeses.

How To Make Zucchini Lasagna

It’s easier than you think to make zucchini lasagna. It’s really all about layering. Watch the video below to see exactly how I do it, step-by-step.

  1. Slice your zucchini lengthwise into slices. If you’d like to make your lasagna less watery, use one of the tips above.
  2. Make your bolognese sauce in a large pan over medium high heat. Break down the ground beef into small pieces and cook until it’s browned. Then, stir in the pasta sauce.
  3. Make the ricotta mix by stirring together the ricotta cheese, parmesan, egg, and some salt and pepper.
  4. Spread 1/2 cup of pasta sauce onto the bottom of the casserole dish.
  5. Place your zucchini slices on top of the pasta sauce, then add 1/2 of the bolognese sauce and spread 1/2 of the ricotta mix evenly on top of that.
  6. Sprinkle 1/2 cup of the grated mozzarella, along with some chopped parsley and basil.
  7. Repeat these layers one more time! Feel free to press down on your zucchini in the second layer to get it nice and flat.
  8. Top the zucchini with a sprinkle of more herbs and 1/2 cup of grated mozzarella.
  9. Pop the lasagna in the oven and let it cook for about 40 minutes. Then let it broil for 5 minutes to get a nice golden brown top.
  10. Garnish with whole basil leaves and serve!

How To Store Zucchini Lasagna

Once the lasagna has slightly cooled, place it in a storage container. It can last for 3-5 days in the fridge or a couple months in the freezer. It’s tasty meal prep for sure!

Ingredients

  • 4 large zucchini
  • 2 pounds ground beef
  • 24 ounces pasta sauce
  • 15 oz ricotta cheese
  • 1 cup shredded parmesan regianno

  • salt and pepper
  • small handful fresh parsley and basil , chopped

Instructions 

  • Preheat the oven to 400 degrees fahrenheit (200 degrees celsius).
  • Slice the zucchini lengthwise into thin slices, as thin or thick as you'd like. Set aside.
  • Add the ground beef to a large pan over medium high heat. Finely break down the ground beef with a spatula and pan fry it until browned and no longer pink.
  • Pour the pasta sauce on top of the ground beef (remember to reserve 1/2 cup) and stir together, then remove from heat.

  • Spread 1/2 cup of pasta sauce onto the bottom of your 9x13-inch casserole dish.
  • Add your zucchini slices on top of the pasta sauce. They can overlap or you can place them side-by-side.
  • Top the zucchini with 1/2 of the bolognese sauce, and evenly spread 1/2 the ricotta mix on top of that.
  • Add 1/2 cup of grated mozzarella on top of the ricotta, along with a sprinkle of chopped parsley and basil.
  • Repeat these layers one more time.
  • Top the lasagna with a final layer of zucchini slices, a sprinkle of chopped parsley and basil, and 1/2 cup mozzarella cheese.
  • Place the lasagna in the oven and cook for 40-45 minutes. Broil for a couple of minutes to get a nice golden top.
  • Garnish with whole basil leaves and serve.

Lisa's Tips

  • I used store-bought pasta sauce (I love Rao's) but if you'd like to make your bolognese from scratch, you can follow my bolognese recipe.
  • This is the mandoline I love...and don't forget to use cut resistant gloves as well.  Your fingers will thank you! 
  • The casserole dish is 9x13 for those looking for exact measurements.

  1. Would it makes sense to leave out the egg? My son’s allergic.

  2. So delicious.  Best I’ve ever made.  One thing is it came out super watery.  What did I do wrong? Even still it was so delicious.  😋

    • Hi Janice – It will most likely be due to the zucchini not being dried out enough. One step you can do is to pan fry the zucchini a bit to remove the moisture.

  3. Delicious recipe!  This is the second time I made it.  Some of our family cannot eat dairy so I used kite hill almond milk ricotta and omitted the other cheese on half.  It was still very good.  Salted the zucchini and let it sit.  Worked perfectly.  Thank you for the recipe!5 stars

  4. This lasagna was amazing. My whole family loved it and had second helpings. This will definitely be a go to meal in my home from now on. Thank you!5 stars

  5. Your recipe was a lifesaver for my husband who loves lasagna but could no longer eat traditional lasagna because of the carbs. Followed your recipe, made sure to salt and squeeze the zucchini slices to get all the water out and it turned out great! Will be making again!5 stars

  6. This is second time making it. First time I did as instructed and it came out perfect.  This time I made it night before and will be baking it later. I suspect it might come out more watery, but will post result after. I love all your recipes!5 stars

  7. What a fabulous recipe!! I used two zucchini instead of four, and a slotted spoon is a must when serving, to help drain out any excess liquid. I was a little worried that the zucchini would water down the flavors but it didn’t at all! I was also afraid the zucchini would come out with a slimy or funny texture but it didn’t! I will be using this recipe again. 5 stars

  8. Unlike many recipes I find online- this one turned out perfectly and tasted absolutely as good as I wanted it to!!  Great job & thanks for sharing! 5 stars

  9. Awesome 👍5 stars

  10. Lisa, I just made this dish, as my husband says THIS IS A KEEPER!!!! This was delicious

    I had a package of mushrooms and browned them with ground turkey instead of beef.

    FYI, if anyone is reading this, you must try the following:

    Chicken Fajitas
    Lentil Soup
    Stuffed Peppers
    Overnight Oats

    Lisa, I can’t wait for your cookbook. If you need recipe tasters, my husband and I have our knives and forks ready.

    Thanks for ANOTHER DELICIOUS RECIPE5 stars

    • Yay, I’m so happy you both loved this recipe, Elayne! And you’re so sweet to list out the other recipes you’ve loved. It puts a big smile on my face to know you’ve enjoyed so many recipes. :) I sincerely appreciate your support and I can’t wait to share more about the cookbook in the future!

  11. You missed a whole step of putting the lasagna at the bottom. Thanks for helping me ruin my first lasagna. Never using you again thats for sure.

  12. I absolutely loved this dish! I’m not much of a cook, but this was really easy to make and it even tasted healthy. My husband really liked it too and he is not exactly health conscious. I will definitely make this one of my go to meals!5 stars

  13. This is a great recipe. I am making it tomorrow but wonder what I can do the day before?
    I can’t find the info in your blog post for this recipe.  Can I make the sauce ahead? Can I cut the zucchini the day before? Help!!!
    BTW I made this in the summer and it was amazing!!!!

    • For this recipe, I think it’s best to make it the day of. But, you can always make the whole recipe the day before and just store it in the fridge. Then warm it up in the oven the next day!

  14. I made this recipe last summer and it was amazingly delicious!5 stars

  15. This is by far my favorite recipe of zucchini lasagna. The cheese mix is awesome. The only thing is that if the zucchini are not cooked a bit in oil before putting them in the dish, it releases a lot of water and you end up with too much liquid in the lasagna.5 stars

  16. Great success!! An overrall nutritional & tasty recipe for the family.5 stars

  17. This an easy and tasty recipe which is now added to my ‘go to’ list of recipes when I need something I know will work. The only thing I did differently is that I used minced Quorn as my husband and I are trying to decrease the amount of red meat we eat, it still tasted great and even means a fewer calories. Thank you again, your recipes are always fool proof and taste great.5 stars

  18. I used my mandoline (which I asked for for Christmas) into very thin slices + or- 1/8 inch. But because we both dislike salt, I placed the slices on sheet pans lined with paper towels and placed them in a 225 F oven for about ten minutes to dry them and soften them. It is a bit of trouble, but really IS worth the bother; the results were wonderful!5 stars

  19. Hi,

    Not sure if this has been answered before, but can I swap out ground beef for ground turkey meat in this recipe?

  20. Could I make/assemble this a day before, put in the fridge and cook the next day?

    • Hi Christina – It’s best to cook it the day of because zucchini will become more watery as it sits.

  21. OMG…. Best Lasagna I have ever had!!!!!!

    I did change a few things. For one I used Hunts meat sauce in a can. I substituted Cottage Cheese for the ricotta cheese. Instead of using parmesan regianno cheese i used parmesan romano and asiago blend. I also used it as a topping with the mozzarella.
    Like I said it is the best I have ever had, My wife agreed also.5 stars

  22. I discovered this site accidentally when I was looking for a shakshuka recipe and I’m so glad I did! I have tried at least 6 of your recipes so far and they were all easy and delicious. I am not a fan of zucchini, but I absolutely loved this lasagna and it was so easy to make. Looking forward to trying even more of your recipes (:5 stars

  23. I don’t cook, but was able to follow this recipe and it turned out great. I used the mandolin to slice zucchini and a little bit of sweet potato, then heated zucchini slices on a pan until very slightly brown and set them on paper towels to blot. I parboiled the sweet potato slices and drained them. Instead of ricotta (couldn’t find), I used the low fat cottage cheese I could find at the store (1:1 ratio) and added another egg in case the cottage cheese would make it too watery. I added onion and garlic before browning the ground beef and added whatever spices I had in my cabinet, and it turned out amazing. Next time I would add more zucchini and less ground beef (just personal preference).5 stars

  24. I was looking for low carb recipes.  I just made this. It is so good!!  I added some spinach to it.  I was hoping the zucchini taste wasn’t gonna be dominant.  I like zucchini but don’t love it. Lol.  Will definitely make this often. Thank you so much.  I can’t wait to look at more of your recipes!!5 stars
