Hello everyone, I would like to say thank to you for all your good wishes to be better I received last post when I was talking about my sciatic nerve pain. The good news is I am almost 100% better. My husband helped me a lot with his massage and some yoga exercise too, which I am not going to give up anymore. Nothing in life is more important than your health. So, don’t stop exercising because it is essential for a healthy body, life and soul 😉

That being said, why not celebrate health with this delicious and skinny Spinach and Zucchini lasagna?!! This is one of my favorite lasagna recipes in the world. Why? Because it is flavorful, but it is not full of carbs and fat like the traditional lasagna recipe.

Instead of lasagna noodles I used zucchini noodles. I sliced the zucchini very thin using my Stainless Steel Mandoline Slicer. It is a very cool and useful kitchen gadget. I got this last Christmas from my mother-in-law and I love it because it makes exceptionally even slices.


It easy to clean but of course you have to be very careful since the blades are very sharp. I love to wear my cut resistant gloves when I am using my mandoline because it gives me more protection.   Spinach and Zucchini Lasagna

I also added spinach in the tomato sauce to load this winner lasagna recipe with more greens. I use skim ricotta and mozzarella cheese because I was trying to save some calories. Please, give this recipe a try. I am sure everybody in your home will love this vegetarian, low carb and gluten-free lasagna.

Did you make this recipe?


  • 1 tbsp extra-virgin olive oil
  • half onion, finely chopped
  • 4 garlic cloves, crushed

  2. Add onions and cook 4-5 minutes until they are soft and golden.

  13. Layer 5 or 6 zucchini slices to cover.
