Preheat oven to 325°F.

Melt butter and combine with Worcestershire sauce. Set aside.

Finely chop onion rings and mix with Parmesan cheese, chicken seasoning and parsley flakes.

Dip chicken in the butter mixture; then dredge in the onion mixture, generously coating each piece.

Place chicken on a baking sheet, and bake for 35 to 45 minutes. Cover loosely with foil during the last 15 to 20 minutes of baking to prevent over browning.
