Instructions

Short Description:
Baked Delaware Bay oysters topped with a buttery spinach-herb and breadcrumb mixture, served as a complete main course with roasted baby potatoes and sautéed greens. Rich, briny oysters and golden topping make a satisfying Mid-Atlantic centerpiece.

Regional Notes:
This Delaware Bay version uses locally harvested Delaware Bay oysters for their distinct sweet-briny flavor and pairs the classic spinach-herb breadcrumb Rockefeller topping with simple regional sides (roasted new potatoes and sautéed spinach) to create a full entrée. The topping emphasizes fresh parsley, chives, and breadcrumbs rather than heavy cream or excessive cheese, reflecting local shellfish traditions.

1. Preheat the oven to 450°F (230°C). Arrange a rimmed baking sheet for the potatoes and a separate shallow baking dish large enough for the oysters; reserve the coarse salt for the oyster bed.
2. Start the potatoes: toss the halved baby potatoes with 1 tbsp (15 ml) olive oil, 2 tbsp (28 g) melted butter, 1/2 tsp salt and 1/4 tsp pepper. Spread them cut-side down on the rimmed sheet and roast 20–25 minutes until fork-tender and golden, turning once midway.
3. Meanwhile, shuck the oysters over a bowl, reserving the liquor. Set oysters on half-shell on a tray on ice. Measure and reserve about 1/4 cup (60 ml) total oyster liquor (from shucked oysters); if short, supplement with 1–2 tbsp (15–30 ml) water.
4. Make the Rockefeller topping: in a medium skillet over medium heat, melt 4 tbsp (55 g) butter with 1 tbsp (15 ml) olive oil. Add the minced shallots and cook 2–3 minutes until softened. Add the minced garlic and cook 30 seconds more.
5. Add the 6 oz (170 g) baby spinach and cook, stirring, until fully wilted and most moisture has evaporated, 2–3 minutes. Stir in the Pernod or vermouth if using; let it reduce by half, 1 minute. Add reserved oyster liquor, Worcestershire, hot sauce, lemon zest and lemon juice; cook 30–60 seconds.
6. Remove skillet from heat. Stir in the breadcrumbs, grated Parmesan, chopped parsley, chives, thyme, and salt and pepper to taste. Add remaining 2 tbsp (28 g) cold butter, cut into small pieces, and stir until incorporated into a loose, spreadable mixture.
7. Prepare the oyster baking bed: spread 1–2 cups (240–480 g) coarse salt evenly in the shallow baking dish so shells will sit level. Place oysters, cupped side down, on the salt bed.
8. Spoon about 1 to 1 1/2 tbsp (15–22 ml) of the spinach-herb-breadcrumb mixture onto each oyster, pressing gently. Sprinkle a light additional pinch of breadcrumbs and a few flakes of butter on top of each for browning.
9. Bake oysters in the preheated 450°F (230°C) oven for 8–10 minutes, until topping is bubbly and golden (watch closely to avoid burning).
10. While oysters bake during their final 8–10 minutes, finish the potatoes if needed and sauté the greens: heat a large skillet over medium-high, add 1 tbsp (15 ml) butter, add 1 sliced garlic clove until fragrant 30 seconds, then add 8 oz (225 g) baby spinach or mixed greens; toss until just wilted, 1–2 minutes. Finish with 1 tbsp (15 ml) lemon juice, salt and pepper.
11. Remove oysters from oven. Plate by arranging roasted potatoes and sautéed greens on each plate and placing 6 oysters Rockefeller per person (for 4 servings) alongside. Garnish oysters and greens with fresh parsley and serve with lemon wedges.
12. Serve immediately with crusty bread if desired and enjoy the sweet-briny Delaware Bay oysters contrasted with the buttery spinach-herb topping and simple regional sides.
