- ½ teaspoon salt
- 1 tablespoon olive oil
Protein Filling
- 1 lb (450 g) lean ground beef, 90–93% lean
- 1 small yellow onion, finely diced
- 3 cloves garlic, minced
- 1 teaspoon Italian seasoning
- ½ teaspoon smoked paprika
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ½ teaspoon red pepper flakes, optional
Creamy Protein Mixture
- 1½ cups (340 g) low-fat cottage cheese
- 2 large eggs
- ½ cup (50 g) grated Parmesan cheese
- ½ teaspoon garlic powder
- ¼ teaspoon black pepper
Cheese Topping
- 1 cup (100 g) shredded mozzarella cheese
- ½ cup (55 g) shredded cheddar cheese
- 2 tablespoons grated Parmesan cheese

Ingredient notes: Use lean ground beef to keep the casserole protein-focused without excessive grease. Ground turkey or chicken can be substituted. Small or medium zucchini generally contains less excess water than very large zucchini.
Directions
- Preheat the oven: Heat the oven to 375°F (190°C).
- Prepare the zucchini: Slice the zucchini into thin, even rounds or half-moons.
- Salt the zucchini: Place the slices in a colander and sprinkle with ½ teaspoon salt.
- Rest: Let the zucchini sit for 10–15 minutes. This draws out excess moisture.
- Pat dry: Blot the zucchini thoroughly with paper towels.
- Sauté zucchini: Heat 1 tablespoon olive oil in a large skillet over medium-high heat.
- Cook briefly: Add the zucchini and sauté for 3–4 minutes, just until slightly softened.
- Don’t fully cook: The zucchini should still have some structure because it will continue cooking in the oven.
- Brown the meat: In the same skillet, add the ground beef and cook over medium-high heat for 6–8 minutes, breaking it apart with a wooden spoon.
- Add onion: Stir in the diced onion and cook for another 3–4 minutes, until softened.
- Add garlic: Stir in the minced garlic and cook for 30–60 seconds, until fragrant.
- Season: Add Italian seasoning, smoked paprika, salt, black pepper, and red pepper flakes if using.
- Drain excess fat: If necessary, carefully drain any excess rendered fat from the skillet.
- Prepare the creamy mixture: In a large bowl, combine cottage cheese, eggs, Parmesan, garlic powder, and black pepper.
- Mix until smooth: Stir thoroughly until the mixture is evenly combined.
- Layer the zucchini: Arrange half of the zucchini in the bottom of a greased 9 × 13-inch baking dish.
- Add meat: Spread half of the seasoned ground beef over the zucchini.
- Add creamy mixture: Spoon half of the cottage cheese mixture over the meat and spread gently.
- Repeat: Add the remaining zucchini, ground beef, and cottage cheese mixture in layers.
- Add cheese: Sprinkle mozzarella, cheddar, and Parmesan evenly over the top.
- Bake covered: Cover loosely with foil and bake at 375°F (190°C) for 20 minutes.
- Remove foil: Carefully remove the foil.
- Finish baking: Continue baking uncovered for another 12–18 minutes.
- Check doneness: The center should be hot and set, while the cheese should be melted and lightly golden.
- Optional browning: For a more deeply browned topping, switch to broil for 1–2 minutes, watching closely.
- Rest: Remove the casserole from the oven and let it rest for 10 minutes.
- Garnish: Sprinkle with fresh parsley if desired.
- Serve: Cut into portions and serve warm.
