🧂 Ingredients
The Oysters:
-
12 fresh oysters (East Coast or West Coast depending on your flavor preference)
-
Crushed ice or rock salt, for serving
-
Lemon wedges, to serve
-
Fresh cracked black pepper, optional
Classic Mignonette:
-
¼ cup red wine vinegar
-
1 small shallot, very finely minced
-
1 tsp freshly ground black pepper
-
Pinch of salt (optional)
Optional Garnishes:
-
Fresh herbs (micro parsley or chervil)
-
Cucumber brunoise or a drop of Champagne for a luxe twist
Execution
1. Make the Mignonette
-
Combine red wine vinegar, minced shallot, and freshly ground black pepper in a small bowl.
-
Let it rest in the fridge for at least 30 minutes to mellow and infuse.
2. Shuck the Oysters
-
Carefully shuck the oysters using an oyster knife and a towel for grip and safety:
-
Insert the knife into the hinge.
-
Twist gently until the shell pops.
-
Slide the knife beneath the top shell to loosen and lift it off.
-
Gently separate the oyster from the bottom shell, taking care to preserve the liquor.
-
-
Place each oyster on a bed of crushed ice or rock salt to keep level.
3. Assemble & Serve
-
Spoon about ½ tsp of mignonette onto each oyster or serve it in a ramekin on the side.
-
Garnish with lemon wedges and optional herbs.
-
Serve immediately—ice cold.

Additional Tips
-
Always smell the oysters before serving. They should smell like the sea—never fishy or off.
-
Keep them ice cold—warm oysters lose their charm quickly. Use crushed ice or rock salt under the shells.
-
No oyster knife? Some seafood markets will shuck to order—just ask and serve immediately.
-
Prefer milder flavor? Substitute with Champagne vinegar or rice wine vinegar in the mignonette.
Q&A about Oysters on the Half Shell with Mignonette
Q: Which type of oysters work best for this recipe?
A: East Coast oysters (like Blue Points or Wellfleets) are saltier and firmer, while West Coast oysters (like Kumamoto or Kusshi) are creamier and sweeter. Pick what suits your palate!
Q: Do I need to rinse the oysters?
A: No—rinsing removes the natural brine (“liquor”) which adds flavor. Just scrub the shells before opening.
Q: Can I make mignonette in advance?
A: Absolutely. It gets better with time. Make it a day ahead and refrigerate.
Q: What drink pairs well with oysters?
A: Champagne, Chablis, Muscadet, or a crisp gin martini are classic oyster pairings.
Q: How long do oysters stay fresh?
A: Ideally, eat them within 1–2 days of purchase. Keep them cold and covered with a damp towel in the fridge.
