Clams Casino

When summer rolls around, I like to fill my days with as much sand, surf and seafood as I can. I know it’s very possible to enjoy seafood all year long but ever since I was little I felt it was a true necessity to eat all the clams, crabs and lobster I possibly could every time we were at the shore.

I still have that urge….to round out every meal with a pile of shellfish and a big bowl of butter for dipping but one of my favorite things to eat ever all year long is Clams Casino. And trust me, I’ve had my fill of bad clams casino so it was important that I made the BEST Clams Casino recipe you would ever sink your teeth into.

What are Clams Casino?

Clams Casino are a “clams on the half shell” appetizer made of chopped clams, bread crumbs and bacon. Originating in Rhode Island, this New England style appetizer is popular all over the United States in various forms.

Many versions of Clams Casino are simply a stuffed clam with the same buttery stuffing baked on top but my version is even better because I tossed chopped clams in the stuffing so you don’t have that one chewy piece that sometimes can just be a bit too chewy. Like a big ball of never ending chewing gum.
