Delicate spinach and ricotta ravioli in light butter and sage sauce define Ligurian simplicity. A vegetarian mediterranean pasta that's high protein and beloved as a healthy family dinner.
Combine the all-purpose flour and eggs in a mixing bowl; knead for 8–10 minutes until a smooth and elastic dough forms, then wrap and rest for 30 minutes.
Meanwhile, sauté baby spinach in 1 tbsp butter over medium-high heat just until wilted for 2–3 minutes. Chop finely and squeeze out excess moisture.
Mix ricotta, chopped spinach, grated parmesan, nutmeg, salt, and pepper in a bowl to make the filling. Chill the mixture while preparing the pasta.
Roll out the rested dough on a lightly floured surface to a thin sheet (about 1/16-inch). Arrange spoonfuls of filling 1 inch apart, fold dough over, and seal edges tightly; cut into individual ravioli.
Boil ravioli in salted water at a gentle simmer for 3–4 minutes until they float. Meanwhile, melt remaining butter in a skillet over medium heat and infuse sage leaves for 2–3 minutes without browning.
Drain ravioli carefully, then transfer to the skillet with sage butter. Toss gently to coat, serve immediately with extra parmesan, if desired.
