Grilled Oysters with Garlic Herb Butter and Chili Flakes Recipe
Introduction
Grilled oysters bring a smoky, buttery flavor to the natural brininess of fresh shellfish. This simple recipe combines a garlicky, spicy sauce with the unique charm of outdoor grilling, making it perfect for a summer gathering or special treat.

Ingredients
- 16 whole live oysters
- 2 cloves garlic, finely minced
- 3 tablespoons extra virgin olive oil
- 3 tablespoons unsalted butter
- 1 teaspoon lemon juice
- 1/2 teaspoon chili pepper flakes (or substitute with dashes of Tabasco)
- 1/4 teaspoon salt
- Freshly ground black pepper, to taste
- 1 tablespoon finely minced parsley
Instructions
- Step 1: Prepare the sauce by heating a small saucepan over medium-low heat. Add the olive oil and butter. Once melted, add the minced garlic and sauté until fragrant, about 30 seconds. Remove from heat and stir in lemon juice, chili pepper flakes, salt, black pepper, and parsley.
- Step 2: If you can shuck oysters, carefully open them, spoon a small amount of sauce onto each oyster, then place them on a very hot, preheated grill. Cover and cook for 5 to 6 minutes until the oyster edges curl slightly.
- Step 3: If you cannot shuck, place the oysters cup side up on the hot grill and cover for 1 minute until they start to open. Remove carefully and use an oven mitt and a shucking knife or clean screwdriver to pry open the oysters.
- Step 4: Spoon sauce into each opened oyster and return them to the grill. Cover and cook for an additional 4 to 5 minutes. Serve hot and enjoy.
Tips & Variations

- For an extra touch, add a sprinkle of grated Parmesan or breadcrumbs before grilling.
- If you prefer, finish the grilled oysters with a squeeze of fresh lemon juice for added brightness.
Storage
Grilled oysters are best enjoyed immediately. If you must store leftovers, place them in an airtight container in the refrigerator and consume within 1 to 2 days. Reheat gently on the grill or under a broiler just until warmed through to avoid overcooking.

FAQs
Can I prepare the sauce ahead of time?
Yes, the garlic butter sauce can be made up to a day ahead and stored in the refrigerator. Reheat gently before spooning onto the oysters.
How do I know if oysters are fresh and safe to eat?
Fresh oysters should smell like the ocean—briny and clean, not fishy or off. Always buy from a reputable source and keep them cold until cooking.

Ingredients
Oysters
- 16 whole live oysters
Sauce
- 2 cloves garlic, finely minced
- 3 tablespoons extra virgin olive oil
- 3 tablespoons unsalted butter
- 1 teaspoon lemon juice
- 1/2 teaspoon chili pepper flakes (or substitute with dashes of Tabasco)
- 1/4 teaspoon salt
- Freshly ground black pepper, to taste
- 1 tablespoon finely minced parsley
Instructions
- Make the sauce: Heat a small saucepan over medium-low heat. When hot, add the olive oil and butter. Add the finely minced garlic and sauté for about 30 seconds until fragrant. Then stir in lemon juice, chili pepper flakes, salt, freshly ground black pepper, and parsley. Remove from heat and set aside.
- Shuck and prepare oysters (if shucking before grilling): Carefully shuck the oysters by opening the shells and detaching the oysters while keeping them on the half shell. Spoon a small amount of the prepared sauce onto each oyster.
- Grill oysters (if pre-shucked): Place sauced oysters directly on a very hot, preheated grill. Cover and cook for 5 to 6 minutes until the oyster edges curl slightly.
- Grill oysters (if not shucked initially): Arrange oysters cup side up on the very hot grill. Cover and grill for 1 minute until they begin to slightly open. Remove oysters from the grill promptly.
- Shuck oysters after partial grilling (if not shucked initially): Holding the oyster with an oven mitt, use a shucking knife or clean screwdriver to carefully pry open each oyster. Spoon the prepared sauce into each oyster shell.
- Finish grilling: Return the sauced oysters to the grill, cover, and cook for an additional 4 to 5 minutes until the oysters are cooked through and sauce bubbly.
Notes
- Be sure to use very hot, preheated grill for the best smoky flavor and proper cooking.
- If you are not comfortable shucking oysters, partially grilling them unopened makes shucking easier.
- Use fresh live oysters for optimal flavor and safety.
- You can adjust the heat level by varying the amount of chili flakes or Tabasco.
- Wear protective gloves or use an oven mitt when shucking to avoid injury.
