Step 1

Bring a pot of salted water to a boil. Cook the ravioli according to the package directions, 4 to 6 minutes. Reserve some of the pasta water, then drain the ravioli and set aside.

Step 2

Put a large straight-sided skillet over medium-high heat and add the olive oil. When it begins to swirl, add the onions, a tiny pinch of salt and plenty of pepper and saute, stirring often, until the onions are golden on parts, about 5 minutes. Stir in the whipped cream cheese and mustard to combine, then slowly stir in the gravy. Bring to a simmer and cook, stirring occasionally, until the sauce is heated through and combined, about 5 minutes. Add some reserved pasta water if needed to reach the desired consistency.

Step 3

Stir half of the parsley into the sauce, then pour the sauce over the pasta and garnish with the remaining parsley.
