Grilled Clams

Clams are naturally sweet and salty, and cooking them over a hot fire adds a perfect layer of smoky flavor. Topping the open clams with slightly spicy and rich horseradish butter makes for a tantalizing appetizer or main dish.

These grilled clams make for a delicious and decadent dinner made even more complete when served with a batch of Grilled Garlic Bread. The bread is perfect for dipping in the luscious pan juices for a tasty meal.

How to Prepare Clams for Grilling

Make sure the clams are fresh and cleaned well before heading to the grill. Begin by scrubbing the shells thoroughly with a brush under cold water to remove any sand or particles from the external shell. You definitely don’t want to be eating any sand with your dinner!

Now, this next step may be optional, as many clams from the stores are already purged of sand. If you are not sure, ask the seller if the clams have been fully cleaned and purged. If you do need to rid your clams of sand and gunk, follow these instructions:

To help clams expel sand, cover them completely in 1/4 cup sea salt (make sure to use sea salt and not table salt) dissolved in 1 liter of water. Soak for 2-3 hours. When you are ready to grill the clams, rinse them again as you preheat your grill.

How to Cook Clams on the Grill

Whether you purchase clams from the store or collect them yourself, they’ll make a great meal this week. Here’s how to cook clams on the grill:

  1. Make the butter. Combine prepared horseradish, Tabasco sauce, melted butter, garlic, lemon juice, and Hey Grill Hey Fish & Veggie Rub in a bowl. Stir to combine and set aside.
  2. Prep the clams. Wash the shells fully and follow the instructions in the previous section to purge your clams of sand and grit as needed. Place the cleaned clams in a 12-inch cast iron skillet on the grill preheated to 400 degrees F.
  3. Grill. Pour a cup of white wine over the clams, close the lid of the grill, and grill for 8-10 minutes. Take care not to overcook the clams. They can become chewy if they are left in the heat too long.
  4. Season. Discard any clams that did not open while grilling. Pour the horseradish garlic butter over the remaining grilled clams and sprinkle chopped chives over the top for garnish.
  5. Serve immediately. These clams are ready to be enjoyed right after they come off the grill. Enjoy!

Tips for Grilling Clams

Hold up! Make sure and read these tips for making grilled clams before you dive into the recipe below!

  • Toss any clams that don’t open on the grill. The steam and cooking process will cause all of the good clams to open and the bad ones will stay sealed shut. If a clam does not open while cooking, it is dead and is not safe to eat. You’ll lose one or two clams, but it’s just a sacrifice you’ve gotta make.
  • Serve individually. For a plated dinner, form 3 open-top boats out of heavy-duty aluminum foil and arrange the clams in the boats. Grill as written in the recipe and serve each boat to your guests. Double the recipe for 6 individual servings.
  • Add carbs. These grilled clams are awesome served with Grilled Garlic Bread for sopping up the juices in the foil. These clams also taste delicious served over a bed of cooked linguine or rice pilaf.
