Preheat your oven to 350°F. Lightly spray a 9x13" baking dish with oil.
You can buy store bought cornbread and cube it or use my delicious recipe linked above. Toast the cubes in your oven, on a baking sheet, for 30 minutes (or until crunchy and golden brown).
In a large deep skillet, heat 3 tbs butter over medium high. Add the onion, pepper and celery and cook for 3 minutes. Season with Old Bay and dried herbs.
Season your shrimp with salt to taste. Add it to the pan and cook for one minute, tossing them around. Transfer this mixture to an extra large bowl. Toss it with the crabmeat and cornbread cubes. Mix in the eggs and broth to coat all. Transfer this mixture to your prepared baking dish and top with remaining butter tabs. Bake for 30-45 minutes. or until golden brown on top.
Notes
You can definitely skip the extra tabs of butter that i add on the top of the stuffing. It will still taste incredible.*Instead of cornbread, you can also chop up a loaf of day old Italian bread into cubes and toast them in the oven.
