Zucchini Lasagna Recipe (Low Carb)

Summer of 2014 was a crazy zucchini year with 30 recipes we developed and we still have have 23 to share. Another zucchini recipe? Sure, why not. It’s such a versatile vegetable and it doesn’t hurt to add more veggies to our daily menu! A few months ago during lunch on-set everyone was talking about their favorite foods. It was a fun round of conversations because everyone had different favorites and of course, they all revolved around comfort foods. One of the food stylists mentioned that she “loves”, meaning all in caps “LOVES”, lasagna. We all had a moment of silence, followed by a unanimous “yes!”. It was quite a bonding moment when we all agreed (and almost forgot about), this favorite comfort food.

Replacing Pasta for Lasagna Slices

It was great that the topic of lasagnas came up because back on our 2014 zucchini project, we made this zucchini “no pasta” enchilada and it was a huge hit. What makes this less calorie and lower carb compared to traditional lasagna is that we didn’t use any lasagna pasta. Instead, we sliced the zucchini very thin length-wise and broiled them. Then we use those to replace the “pasta” in layering. Trust us, you really don’t miss all the pasta layers and will probably be glad to have some less carbs if you’re a double or triple-serving type of person. The only thing different with using the zucchini slices to replace the pasta in this zucchini lasagna is that you’ll have more water-release from the zucchini.

Make Ahead and Perfect for Leftovers

You can easily make a batch of this the night before and heat it up the next day before serving. We made this zucchini lasagna dish again the next day for the crew and everyone loved it. They couldn’t believe that there was no pasta and best of all, it was lower in carbs and just as satisfying. We were obsessed and also made a enchilada version of this using the zucchini instead of tortillas. We’ll be posting the zucchini enchilada recipe soon!

Adjust baking time a bit shorter so zucchini doesn’t become too mushy. Some moisture from zucchini will release but not as much as using raw zucchini. Overall textures of the zucchini will be slightly softer, so don’t over-bake.

Thanks to that awesome day in studio with all the stylists for reminding us how much we all love (but don’t eat often) lasagna. Now we need to make this zucchini lasagna again and serve beer on the side. Enjoy.

Three Cheese Zucchini Lasagna “No Pasta”

One of the main differences with using the zucchini slices to replace the pasta is that you’ll have more water-release from the zucchini. To help minimize moisture and water released from the zucchini after baking, you can pre-broil the zucchini slices first. Broiling will help release a substantial amount of moisture and give add flavor to the zucchini. Water will still be released when the zucchini is pre-broiled, but it’s not that bad. 
Also, the homemade tomato sauce is “thick” which reduces amount of water released. If you use canned sauce, drain out some of the moisture. We’ve tested both versions and both are great. 
But you need less lasagna cooking time if you pre-broiled the zucchini so you don’t end up with zucchini-mush. Usually the pre-broiled slice zucchini lasagna will be about 30 minutes, and the raw zucchini slice lasagna will be about 40 minutes, however every oven will vary so adjust accordingly to your own oven. Personally, we prefer using the raw zucchini because the texture has a little more of and “al dente” bite and zucchini isn’t too soft. But as mentioned above, it will have a bit more released water than the pre-broiled zucchini slices.

  • 1 ½ cups (370 g) ricotta (15oz or 425 grams)
  • 4 ounces (113 g) shredded Parmigiano Reggiano cheese (1 cup)
  • 1 large egg

  • 4 ounces (113 g) grated smoked gouda , cheddar, jack or any good melting cheese (1 cup)
  • optional garnish of minced parsley or fresh cracked black pepper

For the Broiled Zucchini slices (optional)


If you are using Broiled Zucchini Option: (If using Raw Zucchini – skip down to Make the Tomato Sauce)

  • Set the oven to broil at 500°F with the rack about 5-inches from the element (usually the second position down from the top).
  • Lay the zucchini slices into single layers on baking sheet pans. (Do not line the baking sheet pans with wax paper or parchment. They will burn.) Lightly brush the zucchini slices with olive oil and season with salt and pepper. Flip over the slices and repeat for the other side.
  • One baking sheet pan at a time, broil for 8 minutes, or until lightly brown. Remove from the oven and allow to cool slightly. Place the slices on paper towels to remove excess moisture. Repeat for remaining slices.

Make the Tomato Sauce

  • Heat a saucepan over medium heat, add olive oil and then add onions and garlic. Cook until translucent, about one minute.
  • Add tomato sauce, tomato paste, sugar, thyme, basil, Worcestershire sauce, salt and pepper. Simmer on low for about 15 minutes or until the sauce begins to thicken. Add additional salt or seasonings to taste. Remove from heat and allow to cool.

Assemble the Lasagna:

  • Pre-heat oven to 400° F  (205°C)
  • In a bowl, combine the ricotta, Parmigiana Reggiano cheese, egg, parsley, and black pepper. Mix until evenly combined and then set aside.
  • In a 3-quart baking dish (9-inch x 13-inch dish) add a very light layer of tomato sauce. Then layer ¼ of the zucchini slices into a single layer covering the base of the pan. Add 1/3 of the tomato sauce, 1/3 ricotta mixture, 1/3 mozzarella and 1/3 of your final cheese choice. Repeat with the layering, until you end with the last layer with zucchini and a little bit of cheese (you should have 4 zucchini layers, and 3 layers with the ricotta and tomato sauce combination).
  • Bake in oven for 30-40 minutes or until lasagna is baked through and cheese is melted. Allow to cool, then serve warm. *Note: If using raw zucchini slices, it will take a little longer to bake compared to the pre-broiled zucchini slices.
    If there is excess water release, you can soak it up with a paper towel. Top with optional garnish and serve warm.
