Classic Clams Casino

Classic clams casino contains bacon, breadcrumbs, bell pepper, clams, butter, and herbs and spices. This classic recipe can easily be varied to suit individual tastes or dietary restrictions as well. This recipe serves six.


  • 2 dozen large clams
  • 8 ounces hardwood smoked bacon, chopped and divided
  • 1 1/2 cups panko-style breadcrumbs
  • 1 teaspoon sea salt, divided
  • 1/4 teaspoon freshly ground black pepper, divided
  • 1/2 red onion or 2 shallots, finely minced
  • 4 garlic cloves, minced
  • 1/2 cup dry sherry
  • Pinch red pepper flakes
  • 1/4 teaspoon smoked paprika
  • 1/4 cup chopped Italian parsley
  • 2 cubes (1 cup) unsalted butter, softened


  1. Submerge the clams in a bucket of fresh, cold water for 30 minutes. Drain the water. Submerge again, repeating until there is no sand in the bottom of the bucket. With a brush, scrub the clams under running water.
  2. Preheat your oven to 450 degrees Fahrenheit.
  3. In a large skillet, cook 6 ounces of the bacon on medium-high until it is crisp, about five minutes. Remove the bacon from the fat in the pan with a slotted spoon and set it aside on paper towels to drain.
  4. Add the breadcrumbs to the fat in the pan and cook, stirring or tossing until golden, about 3 minutes. Transfer to the bowl with the bacon and season with 1/2 teaspoon of the sea salt and 1/8 teaspoon of the black pepper. Set aside.
  5. In a large pot, cook the remaining 2 ounces of bacon on medium-high until it is crisp, about five minutes.
  6. Add the onions or shallots and cook until they are soft, about five minutes.
  7. Add the garlic and cook, stirring constantly, for 30 seconds.
  8. Add the sherry, red pepper flakes, smoked paprika, and clams. Bring to a simmer. Cover and cook on medium-low until the clams open. As the clams open, remove them from the pot with tongs and cool them in a bowl.
  9. Remove the lid from the pot and turn the heat up to medium-high. Cook, stirring until the liquid evaporates. Be careful you don't burn the bacon and vegetables.
  10. When the liquid has evaporated, cool the bacon and the shallots.
  11. In a bowl, mix half of the cooled breadcrumbs, cooled shallots and bacon, parsley, and the remaining 1/2 teaspoon of salt and 1/8 teaspoon of black pepper. Mix well.
  12. Pry the top shells from the clams (a butter knife should work for this - wrap your hand holding the clams in a towel to protect it).
  13. Place the clams open side up on a rimmed baking sheet.
  14. Spoon the breadcrumb mixture into the clam shells on top of the cooked clams, packing it tightly and mounding it. Sprinkle the remaining breadcrumb mixture over each of the clams, pressing gently to set it.
  15. Bake in the preheated oven until the butter melts and the clams warm, three to five minutes. Serve immediately.

  • Turn up the heat by adding 1/2 teaspoon Sriracha to the liquid in step 9.
  • Add 1/2 teaspoon of grated orange or lemon zest to the cooking liquid when you add the clams.
  • Add 1 bell pepper of any color, finely chopped, when you add the shallots.
  • Replace the parsley with an equal amount of chopped fresh basil, chopped fresh thyme, or chopped fresh cilantro.
