Sweet butternut squash, amaretti, and mostarda fill these delicate Mantuan pasta parcels. A vegetarian mediterranean classic that balances sweet and savory for a memorable family dinner.
Roast the butternut squash at 375°F for 45 minutes until very soft and slightly caramelized; allow it to cool, then mash thoroughly.
Mix the mashed squash with crushed amaretti cookies, mostarda, Parmigiano Reggiano, 1 egg, nutmeg, salt, and pepper to form a smooth filling.
Make the pasta dough by combining all-purpose flour, 1 egg, a pinch of salt, and enough water to bring together. Knead for 8 minutes until elastic, then let rest for 20 minutes covered.
Roll out the dough on a floured surface until it is very thin (about 1/16 inch). Cut into 3-inch squares and place a teaspoon of filling in the center of each, moistening the edges to seal into tortelli shapes.
Cook the tortelli in gently boiling salted water for 3–4 minutes; drain carefully. Briefly sauté in melted butter, then serve topped with extra Parmigiano Reggiano.
