Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Heat a skillet over medium heat. Cook the ground beef, chopped onion and minced garlic, breaking up the beef, until no pink remains and the beef reaches 160°F (71°C), about 8 minutes. Drain off the fat and let cool.
In a bowl, mix the cooled beef mixture with the ricotta, Parmesan, parsley and egg. Season with salt and ground black pepper to taste.
Lay out the wonton wrappers. Place a spoonful of filling in the center of half the wrappers. Brush the edges of each with beaten egg yolk.
Top each filled wrapper with a second wrapper. Press out any air and seal the edges firmly, then crimp with a fork.
Bring a large pot of salted water to a boil, then reduce to a gentle simmer. Cook the ravioli in batches for 3 to 4 minutes, until the wrappers are tender and the filling reaches 165°F (74°C).
Lift the ravioli out with a slotted spoon and serve.
