How To Make Zucchini Lasagna

This recipe is made with only wholesome ingredients. The dish is made by alternating layers of zucchini noodles, meat in its sauce, and cheese sauce before adding cheese on top.


For the Zucchini Noodles:

  • Zucchini – zucchinis are a low-carb vegetable that can release quite a lot of water. After all, it’s made of 95% water! Read my tips on how to remove as much moisture as possible to have lasagna that aren’t watery.
  • Salt

For the meat sauce

  • Olive Oil – prefer an extra-virgin olive oil for better taste.
  • Diced Onion – fresh or frozen, pick what you prefer.
  • Green Pepper
  • Oregano
  • Italian Seasoning
  • Parsley – I like Italian parsley, but you can also add some fresh basil.
  • Garlic
  • Ground Beef – choose good quality grass-fed beef for the best taste.
  • Salt 
  • Marinara sauce – tomatoes are keto-friendly vegetables. However, some tomato sauces contain added sugar. So always check the ingredients list. You must see only tomatoes, salt, or preservatives but no added sugar.

For the Ricotta Cheese Sauce:

  • Ricotta Cheese – ricotta is a low-carb cheese, perfect to give a very creamy taste.
  • Parmesan Cheese
  • Egg – prefer free-range eggs to get a strong yellow yolk with more flavors.

Slicing The Zucchinis

Zucchini noodles are long, thin ribbons of zucchini that mimic the regular lasagna sheets in a zucchini lasagna.

To create perfect zucchini layers for your lasagna, you must follow 3 steps.

For this recipe, you will use about 3 large zucchinis of about 10.5 ounces (300g) each.

First, wash the zucchinis, pat them dry with paper towels, keep the skin on, and trim the ends.

Next, use a mandolin set on 1/8-inch (0.3mm) thickness, and slice the zucchini lengthwise to form long, thin zucchini noodles.

Finally, place all the zucchini ribbons into a colander.

Salting The Zucchini Noodles

You must extract all the water from the zucchini before using your zucchini noodles to avoid a watery lasagna.

To do so, sprinkle 1 teaspoon of sea salt all over the prepared noodles.

Then, toss with your hands to bring the salt in contact with all the entire zucchini. Set aside 20 minutes to let the zucchini sweat and extract their water.

After this time, the zucchini noodles will be thinner, softer, and look sweaty on the surface.

Drying The Noodles

The last step consists of removing the water from the surface of each zucchini noodle.

The more water you pat dry, the less watery your lasagna dish will be.

First, lay a large piece of absorbent paper onto your countertop, about 12 inches (30 cm).

Then, lay each zucchini side by side, but do not let them overlap if you can. Press another paper towel on top and gently extract all the water from the zucchinis.

Your noodles are now ready to be used, set aside on a plate.

Making The Ricotta Cheese Sauce

This lasagna recipe is perfect for people on a keto diet because it doesn’t use a regular white sauce that contains wheat flour, milk, and lots of carbs.

Instead, the white sauce is made with two cheese varieties: ricotta and parmesan.

Make the ricotta mixture by combining the cheese with the egg in a saucepan over medium high heat until it has melted and thickened.

Assembling Zucchini Lasagna

As for regular noodle lasagna, you will assemble layers of ingredients until you fill your 9-inch x 13-inch baking dish.

This recipe makes 3 layers of veggies, which means that for each layer, you will use about 1/3 of the total amount of each ingredient: meat sauce, white sauce, and zucchini noodles.

Since the shredded mozzarella cheese is also used on top of the dish, you will use only 1/4 of the total amount per layer.

Like any other lasagna dish, it doesn’t have to be overly precise.

Do your best to add a similar amount of each sauce between the zucchini pasta layers to make the dish balanced.

However, it would still taste good if you did not. If you want to reduce saturated fat in this dish, you can use some low-fat shredded mozzarella.

  • Add about 1/2 cup of meat sauce to the bottom of the baking dish.
  • Top with zucchini slices to fully cover the pan, don’t overlap the zucchini strips but place them side by side until you can’t see the bottom of the pan or the meat tomato sauce.
  • Sprinkle 1/4 of the amount of shredded mozzarella cheese on top of the zucchini layers.
  • Add more meat sauce (about 1/3 of the amount of the remaining sauce).
  • Add dollops of ricotta cheese sauce, about 1/3 of the amount.
  • Top with zucchini ribbons, as before don’t overlap, place them side by side until it fully hides the layer of meat/ricotta created under it.
  • Repeat these steps until the dish is full and finish with a layer of shredded mozzarella cheese.

Baking Zucchini Lasagna

Bake the dish at 400°F (200°C) for about 20 to 30 minutes.

You know it’s ready when bubbles form on the sides of the baking dish, and the baked zucchinis are soft but still tender if you insert a knife into the dish.

Cool Down To Avoid Watery Servings

Zucchini lasagna can look unappealing even though they are extremely tasty!

In fact, even if you successfully extracted all the water from the zucchini, the dish can still be slightly more watery than regular lasagna simply because it consists of mostly liquid layers.

However, the longer the dish cools down, the less watery/soupy the lasagna will be.

If you really want to serve beautiful zucchini lasagna, make the dish ahead, and store it in the fridge overnight. Slice them cold the next day and rewarm in the microwave or oven on a single-serve dish/plate.

Honestly, I care about taste more than presentation when it comes to lasagna, so I usually only cool the dish for 15 minutes at room temperature.

Zucchini lasagnas are juicy, and there is nothing better than a piece of keto bread to dip in the meat marinara sauce!

I recommend a piece of my keto garlic bread or keto bread rolls. It will pair really well with this low-carb keto lasagna dish.

Storage Instructions

This zucchini lasagna is even better the next day.

Store them in the fridge, directly in the pasta dish, covered with plastic wrapping to prevent the top of the dish from drying out.

Keep it there for up to 4 days or freeze the zucchini lasagna in individual containers.

Defrost the fridge the day before. Rewarm them in a saucepan or microwave.

  • Preheat the oven to 400°F (200°C). Grease a 9 x 13-inch baking dish with oil spray or olive oil. Set aside.

Prepare the zucchini ribbons

  • Trim zucchini ends, don't peel the skin off, then slice lengthwise into thin ribbons of about 1/4 inches (0.5 mm). It doesn't have to be precise. Just avoid too thin layers that will break into pieces. You can either use a mandolin or a knife to achieve this.
  • Place all the zucchini ribbons in a colander, sprinkle 1 teaspoon of salt over them and toss with your hands to bring the salt in contact with all the surface of the zucchini ribbons. Set aside 20 minutes to let the zucchini extract their water. Meanwhile, make the meat sauce.

Make the meat sauce

  • In a large saucepan or skillet, heat olive oil under medium heat.
  • Stir in diced onion and cook for 1-2 minutes until translucent and fragrant.
  • Stir in diced pepper and cook for 1 minute.
  • Add in ground beef, dried oregano, garlic powder, and Italian seasoning.
  • Cook and stir until the meat is no longer pink.
  • Add in marinara sauce, cover, bring to boil, then reduce heat to low and simmer for 10 minutes until sauce thickens slightly. Meanwhile, prepare the ricotta sauce.

Make the ricotta cheese sauce

  • In a medium-size mixing bowl, beat egg with Parmesan and ricotta cheese. Set aside.

Pat dry the zucchini noodles

  • To avoid watery zucchini lasagna, pat-dry each zucchini ribbon between pieces of absorbent paper. Lay a large piece of absorbent paper on your countertop, about 30 cm long. Arrange zucchini ribbons next to each other, don't overlap if you can, add the same size absorbent paper on top, and press gently to pat dry and remove excess water. Set side dried noodles on a plate.

Assemble the zucchini lasagna

  • You will form 3 layers of zucchinis with this recipe. Start by covering the bottom of the pan with 1/2 cup of meat sauce, then cover with zucchini ribbons. Place the zucchini noodle next to each other to fully cover the dish. Watch my video for technique.
  • Sprinkle 1/4 of the total amount of shredded mozzarella cheese all over the zucchini noodles, then spread the meat sauce (roughly 1/3 of the remaining volume of sauce).
  • Top up with dollops of ricotta cheese sauce, same roughly 1/3 of total volume. Repeat the layering process of adding zucchini ribbons, shredded mozzarella cheese, meat sauce, and ricotta dollops until 3 layers of zucchini are formed and no more sauce is left. To finish, top up with leftover grated mozzarella.
  • Bake uncovered for 20-30 minutes or until bubbles form on the side of the dish and the zucchinis are still tender if you insert a knife in the center of the dish. After this time, turn the oven to broil mode and broil cheese for 2-3 minutes if desired.


  • Zucchini lasagna always has a more watery aspect than regular lasagna when served. It is better served in a shallow bowl. To prevent it from becoming too watery, cool in the baking dish 15 minutes before cutting and serving. This recipe serves 12 portions.

Storage and freezing

  • This zucchini lasagna is even better the next day. Store in the fridge, directly in the pasta lasagna dish, covered with some wrap to prevent the top of the dish from drying out. Keep up to 4 days in the fridge or freeze in individual containers. Defrost the fridge the day before. Rewarm in a saucepan or microwave.
