Oysters with Apple & Horseradish Dressing Recipe
Introduction
These oysters with apple and horseradish dressing make a refreshing and elegant starter that’s perfect for impressing guests. The sharp tartness of the apple combined with the spicy kick of horseradish complements the briny oysters beautifully. This dish is simple to prepare but feels truly special.

Ingredients
- 24 fresh oysters (3 oysters per person)
- Crushed ice or rock salt
- 3 tbsp white wine vinegar
- 2 tbsp finely chopped shallots
- 1 tsp honey
- 4 tbsp rapeseed oil
- 2 tbsp finely chopped apple flesh (a sharp-tasting variety is best)
- 1½ tbsp freshly grated horseradish
- 1 tsp roughly crushed white peppercorns
Instructions
- Step 1: Mix the white wine vinegar and shallots in a small bowl, cover, and let sit for about an hour to let the shallots infuse the vinegar. Then add the honey, rapeseed oil, chopped apple, grated horseradish, and white peppercorns. Stir well and transfer to a serving bowl.
- Step 2: Carefully shuck the oysters using an oyster knife. Rinse them under cold running water and discard any that are open and do not close when tapped. Place each oyster rounded-side up on a surface, grip it with a tea towel, and insert the knife tip at the hinge. Twist gently until the shell pops open, keeping the oyster level to retain its liquor.
- Step 3: Pry open the shell by wedging the knife tip around the hinge and twist to release it completely. Slide the knife under the oyster to detach it from the top shell, discarding the upper shell, then detach it from the bottom shell while keeping the oyster nestled inside. Discard any oysters with a strong sulfur smell.
- Step 4: Place each oyster in its bottom shell on a bed of crushed ice or rock salt to keep them level. Repeat with remaining oysters.
- Step 5: Serve immediately with the apple and horseradish dressing. Use about a quarter teaspoon of dressing per oyster, either adding it just before eating or dressing all oysters in advance with a dill sprig on top if desired.
Tips & Variations
- Use a sharp oyster knife and protective glove or tea towel to safely shuck oysters.
- Choose a crisp, tart apple like Granny Smith for the dressing to balance the oyster’s flavor.
- For a smoky twist, add a few drops of smoked paprika or a splash of smoky whisky to the dressing.
- If fresh horseradish is not available, substitute with prepared horseradish but reduce the quantity to taste.
Storage
Fresh oysters should be consumed the same day they are shucked for the best taste and safety. Store unshucked oysters in the refrigerator covered with a damp cloth for up to 2 days. The dressing can be refrigerated in an airtight container for up to 2 days but is best served fresh. Reheating oysters is not recommended as it changes their texture and flavor.

FAQs
Can I prepare the dressing ahead of time?
Yes, you can prepare the apple and horseradish dressing up to a day in advance. Letting the shallots infuse in vinegar for at least an hour improves the flavor. Keep it refrigerated until serving.
How do I know if an oyster is fresh and safe to eat?
Fresh oysters should be tightly closed before shucking or close when tapped. Discard any that remain open or have a strong, unpleasant smell after opening. The oyster liquor should be clear and salty, not cloudy or off-putting.

Oysters with Apple & Horseradish Dressing Recipe

- Yield: 8 servings (3 oysters per person) 1x
- Diet: Gluten Free
Description
A refreshing and elegant seafood appetizer featuring fresh oysters served on a bed of crushed ice with a vibrant apple and horseradish dressing, balancing sharp, tangy, and spicy flavors.
Ingredients
Oysters
- 24 fresh oysters (3 oysters each)
- Crushed ice or rock salt (for serving)
Dressing
- 3 tbsp white wine vinegar
- 2 tbsp finely chopped shallots
- 1 tsp honey
- 4 tbsp rapeseed oil
- 2 tbsp finely chopped apple flesh (a sharp-tasting variety is best)
- 1½ tbsp freshly grated horseradish
- 1 tsp roughly crushed white peppercorns
Instructions
- Prepare the dressing: In a small bowl, combine the white wine vinegar and finely chopped shallots. Cover and let it infuse for about an hour to allow the shallots to soften and flavor the vinegar deeply. Afterward, stir in the honey, rapeseed oil, chopped apple, freshly grated horseradish, and crushed white peppercorns until well mixed. Transfer the dressing to a serving bowl.
- Shuck the oysters: Using an oyster knife and a protective tea towel, rinse the oysters under cold running water. Discard any oysters that are open and fail to close when tapped. Place each oyster rounded-side up on a work surface, hold it firmly with the towel, and insert the knife between the shells near the hinge. Twist and wiggle gently until the shell pops open.
- Release the oyster: Carefully run the knife tip around the inside of the shell to detach the upper shell completely, taking care to keep the oyster level to retain its liquor. Then, cut the muscle attaching the oyster to the bottom shell and gently free the oyster while keeping it nestled in the bottom shell. Discard any oyster that emits a strong sulphurous smell.
- Serve the oysters: Arrange the shucked oysters on a bed of crushed ice or rock salt to keep them level and fresh. Either pre-dress each oyster with about ¼ tsp of the apple and horseradish dressing and garnish with a dill sprig, or allow guests to add the dressing themselves. Serve immediately for optimal freshness and flavor.
Notes
- Use an oyster knife specifically designed for shucking to avoid injury and damage to the oysters.
- Choose sharp, tart apples such as Granny Smith to complement the horseradish’s heat with acidity and sweetness.
- Keep oysters chilled on crushed ice or rock salt to preserve freshness and presentation.
- Discard any oysters that do not close when tapped or have an off-smell indicating they are no longer safe to eat.
- The dressing can be prepared in advance to allow flavors to meld beautifully.
- Handle oysters carefully to retain their briny liquor inside the shell for maximum flavor.
