Preheat the oven to 375°F. Spray a 9x13-inch baking dish with non-stick cooking spray. Set aside.
In a medium shallow bowl or pie plate, mix together the egg and the milk. Set aside.
In another pie plate or shallow bowl, gently whisk together the cracker crumbs, garlic powder, onion powder, salt, ground black pepper, and poultry seasoning.
One at a time, dip the chicken pieces into the egg mixture, dredge them in the crumb mixture, making sure to thoroughly coat each piece, then place them in the prepared baking dish.
Drizzle the melted butter over the top of the chicken. Bake for 40 minutes, until the chicken is no longer pink inside, and a meat thermometer reads 165°F.
Notes
To crush the Ritz crackers quickly and easily, put them in a large ziplock bag and use a rolling pin to turn them into cracker crumbs.
You can mix it up by using different spices in the crumb mixture. Italian seasoning works very well.
After putting the chicken into the baking dish you can sprinkle a little more of the crumb mixture on top before drizzling the butter over it if you want a thicker crumb coating.
