Wonton wrappers are key for quick homemade ravioli. Chill uncooked ravioli, wrapped, up to 1 day, or freeze in a single layer, then store in a zip-top bag, up to 1 month.
- Coarse salt and ground pepper
- 1 bunch kale (3/4 pound), tough stems and ribs removed
- 1 3/4 cups ricotta
- 1/3 cup grated Parmesan
- 1 garlic clove, minced
- 48 square wonton wrappers (from a 12-ounce package)
- 4 cups marinara sauce, warmed
In a large pot of boiling salted water, cook kale until tender, 4 minutes. With a slotted spoon, transfer kale to a colander. When cool enough to handle, squeeze out excess water and finely chop. In a medium bowl, mash together kale, ricotta, Parmesan, and garlic; season with salt and pepper.
Assemble ravioli: Arrange 6 wrappers on a work surface, keeping remaining wrappers covered with a damp towel. Spoon a scant tablespoon kale mixture in center of each wrapper. With a fingertip, moisten edges of wrapper with water, then fold over filling to form a triangle and press to seal (flatten area around filling to eliminate air pockets). Place ravioli on a parchment-lined baking sheet and cover with a kitchen towel. Repeat with remaining wrappers and filling.
Return salted water to a boil; reduce to a bare simmer. Drop half the ravioli into water, one at a time, stirring gently to prevent sticking. Cook until al dente, about 3 minutes. With a slotted spoon, transfer ravioli to a paper-towel-lined baking sheet, arrange in a single layer, and let drain briefly. Repeat with remaining ravioli. Serve topped with sauce.
