Prepare and cook 7.5 oz cornbread mix according to directions.
After cornbread is cooked, crumble cornbread into a large mixing bowl.
Add in the finely chopped 1 onion, 15 oz can evaporated milk, 1 sleeve saltine crackers crushed, 1 package Pepperidge Farms herbed stuffing mix, and 32 oz turkey or chicken broth. Mix well. It should be soupy.
Place dressing mix in a large 13x9 in greased baking dish.
Slice 1 stick of butter into several small pieces and evenly arrange slices of butter on top of dressing. (This keeps the top from drying out and creates a nice buttery taste.)
Bake uncovered at 350 for about 40 minutes. You do not want it to dry out.
Allow it to set for 10 minutes before serving.
Notes: ALWAYS use Herbed Seasoned Pepperidge Farm Stuffing Mix. You can use classic or cubed.
