JC’s note: you can absolutely make this ahead and refrigerate overnight. That said, it will turn out wonderful if you make it the day-of as well. Further, I call for Old Bay Seasoning in this recipe, which has a high salt content. As such, please use kosher salt sparingly in the egg mixture.

About Old Bay Seasoning: My Seasoning of Choice for Seafood

Old Bay Seasoning features a blend of celery salt, paprika, black pepper, crushed red pepper, and many more spices. Originally created in Baltimore, Old Bay Seasoning is named after the Old Bay Line, a passenger ship line that plied the waters of the Chesapeake Bay from Baltimore to Norfolk, Virginia, in the early 1900s. The seasoning is regionally popular across Maryland, the Mid-Atlantic States, the Southern States, the Gulf Coast, and parts of New England.

    I’m not quite certain you can call this a Crab Casserole with only 4 oz. of crab. I believe I would double or triple the crab.

      You can absolutely double or triple the crab to your liking! I find crab to be very potent and rich (though I love it); the first time I made this recipe, I used 8 oz. and I found it too overpowering. I cut it in half and liked it much more. Hope you love it!

    How would this be served at room temperature? Hoping to bake early in am due to heat and needing to cool down the kitchen?
