Cut the zucchinis into 1/2-inch thick slices. Grill or broil the zucchini slices until both sides are browned. Lay the zucchini slices in a single layer at the bottom of your baking dish.

Chop the mushrooms and sauté them in a skillet over medium heat with olive oil until they turn golden brown. Season with salt. Spread the cooked mushrooms over the zucchini layer.

Pour the Alfredo sauce evenly over the zucchini and mushrooms. Sprinkle the grated mozzarella cheese on top. Bake the dish in the oven at 350°F for around 15 minutes, or until the cheese is melted, golden, and bubbly.

Serve immediately while the cheese is still gooey and melted. Enjoy your meal!
