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.

  1. Dice your onion and garlic very fine because we don’t want a chunky sauce.
  2. Prepare the zucchini lasagna noodles. The best way to get perfect zucchini slices is to use a mandoline. You can use a sharp knife to cut thin zucchini slices, but that is more time and energy-consuming method.
  3. Make the bolognese sauce: saute the onion and the garlic for about 2 minutes until they are soft and golden.
  4. Add the ground beef and brown for 5-10 minutes until no longer pink. Drain the excess fat.
  5. Add the crushed tomatoes and seasonings.
  6. Stir to combine the ingredients. Simmer on low for 5 minutes until the sauce slightly thickens.
  7. Make the cheese layer:  mozzarella, ricotta, and parmesan
  8. Assemble the lasagna: Start with a layer of meat sauce, zucchini, cheese, meat sauce, zucchini. Repeat!
  9. Bake the zucchini in the preheated oven for about 50 minutes. Let it cool before serving and enjoy!

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 on 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.

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.
