Full Ingredients

Bread & Butter

• 1 lb day-old rustic white or country bread, cut into 3/4-inch cubes (about 10 cups)
• 7 Tbsp unsalted butter, divided (1 Tbsp for the dish, 3 Tbsp for sautéing, 3 Tbsp melted for drizzling)

Aromatics & Herbs

• 1 1/2 cups diced yellow onion (about 1 medium)
• 1 cup diced celery (2–3 ribs)
• 1/4 cup finely chopped flat-leaf parsley, plus more for garnish

Oysters & Custard

• 1 pint (16 fl oz) freshly shucked oysters, with their liquor
• 1 3/4 cups low-sodium chicken or seafood stock
• 2 large eggs
• 3/4 tsp kosher salt (adjust to taste)
• 1/2 tsp freshly ground black pepper

Optional Add-Ins

• Pinch of cayenne or Old Bay, to taste
• Extra chopped parsley or celery leaves for garnish

Step-by-Step Instructions

Step 1: Prep the oven and pan

Heat the oven to 350°F. Generously butter a 9×13-inch casserole dish with 1 tablespoon of the butter. If your bread isn’t quite dry, spread the cubes on a sheet pan and toast in the oven for 8–12 minutes, stirring once, until the edges feel slightly crisp but not deeply browned. Let cool slightly.

Step 2: Sauté the aromatics

Melt 3 tablespoons butter in a large skillet over medium heat. Add the diced onion and celery with a pinch of salt. Cook, stirring occasionally, until tender and translucent, 8–10 minutes. You want them soft and sweet, not browned. Remove from heat.

Step 3: Prep and strain the oysters

Pour the oysters through a fine-mesh strainer set over a bowl to catch the liquor; measure out 1/2 cup of liquor (top up with stock if you’re short). Check for any shell fragments. Chop the oysters into 1/2-inch pieces; keep them in the fridge while you mix the custard.

Step 4: Whisk the custard

In a large bowl, whisk together the eggs, stock, reserved 1/2 cup oyster liquor, kosher salt, and black pepper until well combined.

Step 5: Combine and soak

In a very large mixing bowl, add the bread cubes, sautéed onion and celery, chopped parsley, and the chopped oysters. Pour the custard over the top and gently fold until every piece of bread is moistened. Let the mixture stand for 10 minutes so the bread can absorb the liquid.

Step 6: Fill the dish and bake covered

Transfer the mixture to the prepared casserole and spread evenly without pressing it down. Melt the remaining 3 tablespoons butter and drizzle over the surface. Cover tightly with foil and bake for 30 minutes.

Step 7: Crisp the top and finish

Remove the foil and bake until the top is golden and crisp and the center is custardy but set, 12–15 minutes more. An instant-read thermometer inserted in the center should register at least 165°F. Rest 10 minutes before serving. Garnish with extra parsley or celery leaves, if desired.

Pro Tips

• Strain oyster liquor through a fine-mesh sieve to catch any grit; this keeps the custard silky.
• Let the mixture rest 10 minutes before baking so the bread hydrates evenly—this prevents dry pockets.
• Use day-old bread for best texture. If very soft, toast briefly to help it hold its shape.
• For extra crunch, broil the top for 1–2 minutes at the end, watching closely.
• Season cautiously—oysters and stock can be salty. Taste the custard before adding more salt.

Variations

• Cornbread Oyster Dressing: Use 50% cornbread cubes and 50% white bread; reduce added salt slightly.
• Herb & Lemon: Add 1 tsp chopped fresh thyme and 1 tsp lemon zest to the custard for a brighter profile.
• Smoky Sausage: Brown 6 oz diced andouille or smoked sausage; fold in with the vegetables.

Storage & Make-Ahead

Refrigerate leftovers, tightly covered, for up to 3 days. Reheat at 325°F, covered, until warmed through, then uncover to re-crisp. Make ahead (unbaked): Assemble through Step 6, cover, and refrigerate up to 12 hours; bake straight from the fridge, adding 5–10 minutes to the covered bake time. Freezer: Bake, cool completely, wrap well, and freeze up to 2 months. Reheat from thawed at 325°F until hot, then uncover to re-crisp. Note: Oysters are delicate; best quality is within the first 24–48 hours.
