Step‑by‑Step Instructions for Oyster Rockefeller Casserole
Step 1: Prep Oysters
Start by rinsing your fresh oysters under cold water to ensure they’re clean. If you have whole oysters, use a towel and an oyster knife to shuck them safely. Aim for a smooth extraction and set the cleaned oysters aside, ready to nestle into your casserole dish later.
Step 2: Sauté Spinach
In a large skillet, melt 2 tablespoons of butter over medium heat. Add 3 minced garlic cloves, sautéing until fragrant, about 1 minute. Then, toss in 4 cups of fresh spinach, stirring until it wilts, which should take about 2 minutes. Remove from heat and let the mixture cool slightly before adding it to the casserole.
Step 3: Prepare Sauce
In a mixing bowl, whisk together 1 cup of heavy cream, 1 cup of grated Parmesan cheese, and a pinch of nutmeg, salt, and pepper to taste. Mix until the cheese has dissolved and the sauce is smooth. This rich and creamy concoction will be the flavorful base of your Oyster Rockefeller Casserole.
Step 4: Assemble Casserole
In a greased baking dish, arrange the oysters in a single layer, ensuring they fit snugly. Spoon the sautéed spinach mixture evenly over the oysters, followed by pouring the creamy cheese sauce over everything. Finally, sprinkle 1 cup of breadcrumbs on top for that irresistible crunchy finish.
Step 5: Bake
Preheat your oven to 375°F (190°C) and bake the assembled casserole for 20 to 25 minutes. You’ll know it’s done when the top is golden brown and the sauce is bubbly. Allow the casserole to rest for about 5 minutes after baking, which helps meld the flavors together beautifully before serving.
Make Ahead Options
These Oyster Rockefeller Casserole preps beautifully for busy nights! You can assemble the entire casserole up to 6 hours before baking. Simply follow the recipe instructions to layer the oysters, sautéed spinach, and creamy sauce, then cover it tightly with plastic wrap and refrigerate.

When you’re ready to serve, simply remove it from the fridge and bake at 375°F (190°C) for 20-25 minutes, until bubbling and golden.
