Pimento Cheese Creamed Spinach is a delicious southern twist on creamed spinach. It's creamy and rich like a traditional creamed spinach, but with lots of cheddar cheese flavor plus the wonderful red specks of color from the diced pimentos.

Add garlic and cook another minute.
Add cream cheese and stir until melted.

Mix in the egg and then all but 1/2 cup of cheddar cheese.Mix in the salt and pepper.
Transfer mixture to prepared baking dish.
In a bowl, combine the melted butter, Panko crumbs and 1/2 cup cheddar cheese. Sprinkle over casserole.
