🛒 Ingredients

• 1 lb (450 g) ground beef
• 2 medium zucchinis, sliced into ¼-inch rounds
• 1 small onion, finely diced
• 1 small bell pepper, diced (optional)
• 2 cloves garlic, minced
• 1 tablespoon olive oil
• 1 teaspoon Italian seasoning
• ½ teaspoon paprika
• ½ teaspoon garlic powder
• Salt and black pepper, to taste
• 1½ cups shredded cheddar cheese
• ¼ cup grated Parmesan cheese
• 2 large eggs
• ½ cup heavy cream (or whole milk)
• 1 tablespoon chopped fresh parsley (optional)

👩‍🍳 Instructions

1. Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
2. Heat the olive oil in a large skillet over medium heat. Add the diced onion and bell pepper and cook for 4–5 minutes until softened. Stir in the minced garlic and cook for another 30 seconds.
3. Add the ground beef and cook until browned, breaking it apart with a spoon as it cooks. Drain any excess grease if necessary.
4. Season the beef mixture with Italian seasoning, paprika, garlic powder, salt, and black pepper. Stir well and cook for another minute.
5. In the same skillet, lightly cook the zucchini slices for 2–3 minutes. This helps remove excess moisture and prevents the casserole from becoming watery.
6. In a medium bowl, whisk together the eggs, heavy cream, and Parmesan cheese until smooth.
7. Arrange half of the zucchini slices in the prepared baking dish.
8. Spread half of the seasoned beef mixture over the zucchini.
9. Sprinkle half of the shredded cheddar cheese on top.
10. Repeat the layers with the remaining zucchini, beef, and cheddar cheese.
11. Pour the egg and cream mixture evenly over the casserole.
12. Cover loosely with foil and bake for 25 minutes.
13. Remove the foil and continue baking for 10–15 minutes, or until the cheese is melted, bubbly, and lightly golden.
14. For a crispier top, broil for 2–3 minutes, watching carefully.
15. Let the casserole rest for 10 minutes before slicing. Garnish with fresh parsley if desired and serve warm.

💡 Tips

• Use lean ground beef to reduce excess grease.
• Swap cheddar for mozzarella, Monterey Jack, or Colby cheese.
• Add mushrooms, spinach, or diced tomatoes for extra vegetables.
• Make it spicy with crushed red pepper flakes or diced jalapeños.
• Leftovers keep well in the refrigerator for up to 4 days and reheat beautifully.
