Cook techniques
Mise en Place
Prepare all your ingredients beforehand. This means crushing the Ritz crackers and measuring out the Panko breadcrumbs, butter, spices, and liquids. Having everything ready will enable a smoother cooking process.
Layering
When assembling the casserole, layer ingredients carefully. Start with the cracker mixture at the bottom, followed by oysters, and repeat these layers to ensure even distribution of flavors and textures throughout the dish.
Butter Melting
Melt the butter before mixing it with the cracker and breadcrumb mixture. This allows for a more even coating and helps the crumbs achieve a crispy texture when baked.
Baking
Ensure your oven is preheated to 375°F before placing the dish inside. This step is crucial for even cooking and achieving that golden brown top crust that is desirable in casseroles.
Serving
After baking, let the casserole sit for a few minutes before serving. This allows the layers to settle and makes it easier to cut and serve. Garnish with fresh parsley and lemon wedges for added brightness and flavor.
