01 - Preheat your oven to 375°F (190°C). Lay each sheet of phyllo pastry on a baking tray, brushing lightly with olive oil or melted butter. Stack, oiling between layers. Cut into shards or strips, sprinkle with sesame seeds if using, and bake for 8–10 minutes, until golden and crisp. Allow to cool and then break into pieces for garnish.
02 - Cook the pasta in generously salted boiling water until al dente. Reserve approximately 1/2 cup of the pasta water before draining the pasta thoroughly.
03 - While the pasta is cooking, heat the olive oil in a large skillet over medium heat. Sauté the finely chopped onion until it becomes translucent, approximately 4 minutes. Add the minced garlic and cook for an additional 30 seconds until fragrant.
04 - Add the chopped fresh spinach to the skillet and cook until it wilts, or if using frozen, until warmed through, about 3–4 minutes. Stir in the thinly sliced green onions, chopped dill, chopped parsley, ground nutmeg, salt, and pepper. Remove the skillet from the heat.
05 - In a large mixing bowl, combine the crumbled feta cheese, ricotta cheese, milk, lemon zest, and lemon juice. Stir until the mixture is mostly smooth.
06 - Add the hot, drained pasta and the cooked spinach mixture to the bowl with the cheese sauce. Toss thoroughly to combine all ingredients. Gradually incorporate the reserved pasta water as needed to achieve a creamy sauce consistency. Adjust the seasoning to your preference.
07 - Plate the pasta and immediately top with the prepared phyllo crisps just before serving to ensure maximum crunch.
