High Protein Zucchini Lasagna Recipe High-Protein

Recipe by Pedro M. A. Neves

This Italian-inspired high protein zucchini lasagna swaps traditional pasta sheets for thin-sliced zucchini to create a nutrient-dense, lower-carb main course. Layered with lean ground turkey, cottage cheese, and mozzarella, it delivers over 30g of protein per serving while maintaining authentic lasagna flavors. Perfect for fitness-focused meals without sacrificing the comfort and satisfaction of a classic Italian dish.

Ingredients

• 4 medium zucchini (about 900g/2 lbs), sliced lengthwise into 1/8-inch strips
• 500g (1.1 lbs) lean ground turkey (93/7)
• 300g (1 cup) low-fat cottage cheese
• 200g (2 cups) shredded part-skim mozzarella cheese
• 50g (1/2 cup) grated Parmigiano-Reggiano cheese
• 400g (14 oz) crushed tomatoes (canned, no added sugar)
• 30ml (2 tablespoons) extra virgin olive oil
• 1 medium onion, finely diced
• 4 cloves garlic, minced
• 10g (2 teaspoons) dried Italian herbs
• 5ml (1 teaspoon) kosher salt
• 2.5ml (1/2 teaspoon) black pepper
• 1 large egg
• 5ml (1 teaspoon) fresh lemon juice

Instructions

1. Preheat oven to 190°C (375°F). Pat zucchini slices dry with paper towels and lightly brush both sides with 10ml (2 teaspoons) of olive oil. Arrange on two baking sheets in a single layer.

2. Roast zucchini for 12-15 minutes until softened but still holding shape. The edges should be lightly golden. Remove from oven and set aside to cool slightly.

3. Heat remaining 20ml (4 teaspoons) olive oil in a large skillet over medium-high heat. Add diced onion and cook for 3-4 minutes, stirring occasionally, until translucent.

4. Add minced garlic to the skillet and cook for 1 minute until fragrant. Add ground turkey and cook for 6-8 minutes, breaking it apart with a spoon, until fully browned with no pink remaining.

5. Stir in crushed tomatoes, dried Italian herbs, salt, and pepper. Simmer for 5 minutes to meld flavors. Remove from heat and add lemon juice. Let cool for 2 minutes.

6. In a bowl, combine cottage cheese, 1 cup (150g) of the mozzarella, Parmigiano-Reggiano, egg, salt, and pepper. Mix until well combined.

7. Spread a thin layer of turkey-tomato sauce (about 120ml/1/2 cup) on the bottom of a 9x13 inch (23x33cm) baking dish. Layer 4-5 zucchini strips over the sauce.

8. Spread half of the cottage cheese mixture over the zucchini layer, then add half of the remaining turkey sauce. Repeat with another layer of zucchini strips, remaining cottage cheese mixture, and remaining turkey sauce.

9. Top with final layer of remaining zucchini strips, then sprinkle remaining 1 cup (50g) shredded mozzarella evenly across the top.

10. Bake at 190°C (375°F) for 25-30 minutes until the cheese is bubbly and lightly golden on top. Let rest for 5 minutes before cutting into 8 equal portions.

Substitutions

• Replace ground turkey with 500g lean ground beef (90/10) for 28g protein per serving and slightly richer flavor.
• Substitute cottage cheese with 300g part-skim ricotta cheese for a slightly creamier texture (maintains 31g protein per serving).
• Use 300g cooked shredded chicken breast instead of ground turkey for 32g protein per serving with leaner profile.
• Replace crushed tomatoes with 400g tomato sauce plus 60ml (1/4 cup) beef or chicken broth for deeper umami flavor.

Tips

• Zucchini releases moisture when cooked; patting dry before roasting prevents a watery lasagna. Light roasting before assembly also helps zucchini hold its shape better during baking.
• Make this dish 1 day ahead: assemble completely, cover, refrigerate, then bake. This allows flavors to meld and actually makes it easier to slice cleanly.
• For meal prep, cool the lasagna completely before cutting. Individual portions can be wrapped and frozen for up to 3 months, then reheated at 160°C (320°F) for 20-25 minutes.
• Do not skip the 5-minute resting period after baking; it allows the structure to set, making portions hold together when served rather than falling apart.

Lasagna verde is traditionally from the Emilia-Romagna region of Italy, though this high-protein version draws inspiration from modern fitness adaptations of Italian classics while respecting the layered structure and cheese-forward tradition of authentic lasagna. The substitution of vegetables for pasta maintains the spirit of Italian cooking's emphasis on fresh, wholesome ingredients.
