Servings

Serves 6 (about 4 clams per person)

Step 1: Steam the Clams

Place the water and white wine in a large pot.

Bring to a gentle boil.

Add the cleaned clams.

Cover with a lid and steam for 5–7 minutes, just until the shells open.

Remove the clams immediately.

Discard any clams that remain closed.

Allow the clams to cool slightly.

Separate the top shell and discard it, leaving the clam attached to the bottom shell.

Arrange the clams on a baking tray lined with rock salt or crumpled foil to keep them level.

Step 2: Prepare the Casino Topping

Cook the bacon until crisp.

Drain on paper towels and finely chop.

In a skillet, melt the butter with the olive oil over medium heat.

Add the shallot and bell pepper.

Cook for about 4 minutes until softened.

Stir in the garlic and cook for 30 seconds.

Add:

  • Panko breadcrumbs
  • Parmesan cheese
  • Bacon
  • Parsley
  • Thyme
  • Paprika
  • Crushed red pepper flakes (optional)

Mix well until the breadcrumbs are lightly toasted.

Season lightly with salt and black pepper.

Step 3: Top the Clams

Preheat the oven to 450°F (230°C).

Spoon about one tablespoon of the breadcrumb mixture onto each clam.

Press gently so the topping stays in place.

Step 4: Bake

Bake for 10–12 minutes, or until the topping is golden brown and crispy.

For extra browning, switch to the broiler for the final 1–2 minutes, watching carefully to prevent burning.

Step 5: Serve

Transfer the baked clams to a serving platter.

Garnish with fresh parsley and lemon wedges.

Serve immediately while hot and crispy.

Expert Tips

  • Use fresh littleneck clams for the sweetest flavor and ideal size.
  • Don't oversteam the clams before baking, as they will continue cooking in the oven.
  • Keep the clams level on the baking tray by using rock salt or tightly crumpled foil.
  • Use panko breadcrumbs for the crispiest topping.
  • Serve immediately to enjoy the best texture and flavor.

Storage Instructions

Refrigerator

Store leftover baked clams in an airtight container for up to 2 days.

Freezer

Freezing is not recommended, as the clams can become rubbery and the topping may lose its crisp texture.

Reheating

Oven

Bake at 350°F (175°C) for 8–10 minutes until heated through and crisp.

Avoid microwaving, as it softens the breadcrumb topping.
