Step 1

Preheat the oven to 350 degrees F. Spray a 9x13 casserole dish with nonstick cooking spray.

Step 2

Cook the pasta shells according to package directions but take them out 1 minute before they are finished. Drain and rinse with cold water. Set aside.

Step 3

While the pasta shells are boiling, in a large bowl combine the ricotta, blue cheese, mozzarella, green onion, ranch dressing seasoning mix, buffalo wing sauce and egg. Add the cooked chopped chicken and stir to combine evenly.

Step 4

Fill each shell with a tablespoonful of the chicken and ricotta mixture and place each in the prepared casserole dish. Sprinkle additional mozzarella, blue cheese, and buffalo wing sauce over the top.

Step 5

Bake at 350 degrees for about 20 to 25 minutes.

Step 6

Top with additional chopped green onions. Serve hot with extra buffalo wing sauce.
