- 1 teaspoon kosher salt, divided
- ½ teaspoon black pepper, divided

Instructions
1. Prepare the Oven
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
2. Prepare the Zucchini
Slice the zucchini into thin rounds. Sprinkle lightly with half of the salt and let rest for 10–15 minutes. Pat dry with paper towels to remove excess moisture.
3. Cook the Beef
Brown the ground beef in a large skillet over medium-high heat. Season with the remaining salt, pepper, and Italian seasoning. Cook until no longer pink, then drain excess fat.
4. Add the Sauce
Stir the marinara sauce into the cooked beef and simmer for 2–3 minutes until well combined.
5. Assemble the Casserole
Spread one-third of the beef mixture into the baking dish.
Layer with zucchini slices.
Sprinkle with mozzarella cheese.
Repeat the layers until all ingredients are used, finishing with a generous layer of mozzarella.
6. Bake
Cover loosely with foil and bake for 20 minutes.
Remove the foil and continue baking for 15–20 minutes, or until the cheese is golden and bubbly and the zucchini is tender.
7. Rest and Serve
Allow the casserole to rest for 10 minutes before slicing. Serve hot with salad, garlic bread, or roasted vegetables.
