We think our mom makes the best Zucchini Lasagna in the world!

And we have been eating hers for years, but since some of us are watching our waistline we decided to take her recipe down a notch, making it completely lighter in calories and fat, and much easier to make than hers.

So we’re excited to share this simple recipe and show you step-by-step this zucchini lasagna we think you will love!

For one thing, we lightened her recipe by roasting the zucchini instead of frying. 

Then we made a very quick and light tomato sauce using fresh ripe tomatoes and cooking them quickly on the stovetop with some olive oil, garlic, and red pepper.  

Plus, we reduced the amount of cheese she uses as well as using low-fat mozzarella cheese.

Also, this is a lasagna that doesn’t require a lot of sauce.  If you add too much sauce, it will give you a “soupy” effect, because it doesn’t contain pasta noodles, or any meat to absorb some of the sauce.  

So the saying goes, “less is more” is applied to this recipe, especially with this lasagna

This zucchini lasagna always turns out great every time we make it.  

It’s no wonder why there never seems to be leftovers when we make it.  It’s the perfect vegetable lasagna to serve as the main course, especially on those meatless weeknights!  

ENJOY!!

  2. What a fabulous idea, and what a great idea to roast the zucchini rather than to saute it. I bet you get a greater depth of flavor that way. This looks great! Bravissime!
