How to Make Roasted Zucchini Parmesan – Lightened! 

For this recipe, roasting slices of zucchini is a simple process.

1.  First, zucchini are simply sliced then toss into a roasting pan with olive oil and salt and roasted in the oven until golden.

Keep in mind, it looks like there is a lot of zucchini in the pan, but they shrink excessively when roasted.

2.  Then they are immediately transferred to a serving platter and topped with a layer of fresh tomato sauce, and a generous amount of grated Parmesan cheese with ribbons of fresh basil.

The zucchini will absorb the tomato sauce along with Parmesan cheese and infuse the aromatic fresh basil better this way.  This is the secret to its amazing flavors!

Plus, this dish is even better if you use a light tomato sauce like our Mom’s Quick Marinara Sauce.

Here’s a Quick Tip!

  • When I make a batch of her sauce, I keep it tightly sealed in a jar and in my fridge so I can use it for recipes like this one. 

  • Her sauce stays fresh for up to four days.

Roasted Zucchini Parmesan is extremely light and flavorful, you’ll be amazed what a wonderful side dish this is!

I used only 4 medium-size zucchini’s to make this as a quick side dish the other night, and it was enough for 3 people.  I do recommend you make more if you are serving more than 3 people. 

It’s so flavorful – you’ll want to eat this dish all by yourself.  It’s that good, and sort of irresistible in some way.

My family loved it!

Next time I think I will double the amount of zucchini’s so I can have leftovers for lunch the next day.

Roasted zucchini Parmesan is a gluten-free, low-calorie zucchini dish and one that will have everyone coming back for more! 

This recipe is adapted from our Mom’s version of zucchini parmigiana.  Only hers is similar to a lasagna, and it’s loaded with layers and layers and it’s weighed down with tons of cheeses including mozzarella. 

Don’t get me wrong, her zucchini parmesan is delicious too, but much heavier.
