I’ve been on the quest for the perfect keto lasagna for a few months now. I can assure you that this recipe is the ultimate keto lasagna recipe. It the absolute perfection and you won’t crave classic lasagna with noodles ever again.

The Best Zucchini Lasagna Ingredients

Zucchini is the perfect vegetable to use instead of lasagna noodles because it’s low in carbs and it doesn’t affect the taste or the texture. These delicious layers of zucchini are topped with super delicious beef tomato, all covered in lots of shredded cheese.

It’s interesting to figure out the veggies are incredible when paired with the right ingredients. Growing up, little did I know about how tasty veggie meals are, I just disliked eating them, and that was it! Just in that one night, my mother made this scrumptious lasagna with delicious meaty and cheesy layers. And that’s when my mother first tricked me into eating zucchini lasagna, and I didn’t even notice a difference. It is that delicious! What’s your favorite meal with hidden veggies?

How to Make Zucchini Lasagna?

The best zucchini lasagna starts with making a perfect low carb bolognese sauce.

What’s a bolognese sauce? It’s a meat-based sauce that has its origins in Bologna, Italy.

The onion and minced garlic infuse the sauce with flavor.

Dice your onion and garlic very fine because we don’t want a chunky sauce.

slice zucchini into thin slices using a mandoline

Prepare the zucchini lasagna noodles. The best way to get perfect zucchini slices is to use a mandoline. You can use a sharp knife cut thin zucchini slices, but that is more time and energy-consuming method.

One thing you need to know is that zucchini is 95% water, so an important step is to get as moisture out of them as possible. That can be easily done, by placing the zucchini slices over some clean paper towels, season with salt with then place another paper towel on top to get rid of the excess water.

Within minutes the paper towels will absorb tons of water. Another great way is to grill each zucchini slice for a few minutes.

Then make the cheese and bolognese lasagna sauce.

Assemble the lasagna: meat sauce, zucchini, cheese, meat sauce, zucchini. Repeat! Let it cool before serving and enjoy!

Tips for Perfect Zucchini Lasagna

  1. To make even thin slices of zucchini you’ll have to use a mandoline. While slicing the zucchini by hand with a knife also works well I love how fast and what perfect slices I get when using a mandoline. Be careful not to cut yourself.
  2. Zucchini absorbs flavors very well, so make sure to use little salt because we don’t want super salty zucchini “lasagna noodles”. I know it’s tempting to use more salt, but trust me it’s not a good option.
  3. To prevent a very watery lasagna you can grill the zucchini to help remove the moisture. This step also contributes to a better overall taste of the lasagna.
  4. Bake the zucchini lasagna uncovered for almost half of the time because it helps the liquid to dry more moisture resulting in a lasagna that holds well together.

Can I make Vegetarian Zucchini Lasagna?

Yes, it’s possible to make a vegetarian zucchini lasagna if you substitute the ground beef with 2 cups of your favorite sauteed vegetables such as mushrooms, red peppers or onions. Then continue assembling the lasagna.
