Why You’ll Love This Recipe

Key Ingredients & Substitutions

  • Zucchini: Fresh medium zucchini works best; yellow squash can be used in a pinch.
  • Cheese: Mozzarella or a mozzarella-cheddar blend melts beautifully; use your favorite melting cheese.
  • Cream cheese: Softened for easy spreading; Greek yogurt mixed with a little mayo works as a lighter option.
  • Tuna: Canned tuna in water or oil, well drained; leftover cooked fish can substitute.
  • Avocado: Ripe but firm for clean slices; omit if preferred and add extra lemon.

Quick Expert Tips

  • Slice the zucchini evenly so it cooks at the same rate and crisps properly.
  • Bake on a wire rack for better airflow and golden edges.
  • Drain the tuna thoroughly to keep the filling from becoming watery.

Recipe Card

  • Prep Time: 10 mins | Cook Time: 20 mins | Total Time: 30 mins | Servings: 2–3 | Calories: 380
  • Ingredients:
    • 2 medium zucchini
    • 100–120 g shredded mozzarella or melting cheese
    • 80–100 g cream cheese, softened
    • 1 can (160–180 g) tuna, drained
    • Juice of ½ lemon
    • 1 ripe avocado, sliced
    • Red pepper flakes, to taste
    • Salt and black pepper to taste
    • Olive oil spray or light oil for the tray
  • Equipment:
    • Sharp knife
    • Baking sheet with wire rack
    • Spatula
    • Mixing bowl
  • Instructions:
    1. Preheat the oven to 200°C (400°F). Slice the zucchini into thin, even rounds about 5 mm thick.
    2. Lightly oil a wire rack set over a baking sheet. Arrange the zucchini rounds in a single overlapping layer to form a roughly rectangular base. Sprinkle evenly with the shredded cheese.
    3. Bake for 15–18 minutes until the cheese is bubbly and golden and the zucchini edges are lightly crisp. Remove from the oven and let cool for a couple of minutes.
    4. Carefully transfer the baked zucchini cheese base to a clean surface or parchment. Spread a generous layer of softened cream cheese over one half.
    5. Flake the drained tuna over the cream cheese. Squeeze fresh lemon juice over the tuna and season lightly with salt and pepper.
    6. Top with sliced avocado and a sprinkle of red pepper flakes. Fold the other half of the zucchini base over the filling to form a melt. Slice and serve warm.

Storage & Reheating

  • Refrigerator: Best eaten fresh. Store leftover components separately in airtight containers for up to 1 day.
  • Freezer: Not recommended, as the zucchini becomes watery when thawed.
  • Reheating: Warm the zucchini base in a 180°C oven for 5 minutes to restore crispness before assembling.
