Preheat your oven to 375°F (190°C) and grease a 9x13-inch baking dish.
Slice the zucchini into thin rounds, approximately 1/4-inch thick.
In a large skillet, heat the olive oil over medium heat. Add the diced onion and sauté for 3-4 minutes, until softened.
Add the minced garlic to the skillet and cook for an additional 1 minute, being careful not to burn the garlic.
In a large mixing bowl, whisk together the eggs, heavy cream, Italian seasoning, salt, and black pepper.
Stir in the shredded pepper jack cheese and cheddar cheese until well combined.
Layer half of the sliced zucchini in the prepared baking dish. Top with half of the sautéed onion and garlic mixture, then pour half of the cheese mixture evenly over the top.
Repeat the layering with the remaining zucchini, onion mixture, and cheese mixture.
In a small bowl, toss the panko breadcrumbs with the melted butter. Sprinkle the breadcrumb mixture evenly over the top of the casserole.
Bake in the preheated oven for 35-40 minutes, or until the casserole is bubbly and the topping is golden brown.
Remove from the oven and let cool for 5-10 minutes before serving. Garnish with fresh parsley, if desired.
