Start by washing your spinach thoroughly and sautéing it lightly with garlic in a skillet. This removes excess water and intensifies the flavor. Once cooled, combine it with ricotta, Parmesan, lemon zest, and seasoning in a mixing bowl.
Lay out your phyllo sheets and brush each one lightly with olive oil. Stack three sheets per cup for extra crispiness. Gently press them into a muffin tin or small cup molds, then trim edges if needed.
Spoon the spinach and ricotta mixture into each phyllo cup, filling it generously but not overstuffing. Bake at 180°C (350°F) for 12–15 minutes until golden and crispy. Let them cool slightly before serving to keep the cups intact.
