My husband is from the South and had mentioned these a few times already

Wash the zucchini thoroughly and slice it into 1/4-inch thick rounds to ensure even cooking and a tender interior.
Season both sides of the zucchini slices with salt and pepper to enhance their natural flavor.
Heat 2 tablespoons of olive oil in a large skillet over medium heat; this temperature allows the zucchini to brown nicely without burning.
Place the zucchini rounds in the hot oil in a single layer and cook for 2 to 3 minutes on each side until they develop a golden brown crust and become tender.
Reduce the heat to low to prevent the cheese from burning when added.
Sprinkle 1/2 cup shredded mozzarella and 1/4 cup grated Parmesan evenly over the zucchini slices.
Cover the skillet and cook for 1 to 2 minutes more, allowing the cheese to melt fully and become bubbly, which adds richness and texture.
Transfer the cooked zucchini rounds to a serving platter and garnish with 1 tablespoon of chopped fresh parsley for a fresh, herbaceous finish.
Serve immediately to enjoy the contrast of crispy zucchini and melted cheese.

Substitute mozzarella with sharp cheddar or pepper jack for a different cheese flavor profile.
Add a sprinkle of crushed red pepper flakes before cooking for a mild spicy kick.
Use olive oil infused with garlic to enhance the savory depth of the dish.
Top with fresh basil or oregano instead of parsley to vary the herb garnish.
Incorporate a light dusting of breadcrumbs before adding cheese to introduce extra crunch.
Mix grated pecorino Romano with Parmesan for a saltier, more robust cheese topping.

Store leftover cooked zucchini rounds in an airtight container in the refrigerator for up to 3 days.
Reheat leftovers in a skillet over medium heat to maintain crispiness rather than microwaving, which can make them soggy.
If preparing in advance, keep the cheese separate and add it just before serving to prevent the zucchini from becoming soggy.
Choosing medium-sized zucchini helps achieve consistent cooking and a pleasant texture.
For best browning results, avoid overcrowding the pan to allow proper heat circulation.
Using freshly grated Parmesan yields better melting and flavor compared to pre-grated varieties.
Adjust salt seasoning cautiously if using salted cheeses to avoid over-salting the dish.
