Ingredients

• 3 dozen fresh oysters, shucked with their liquor reserved
• 4 tablespoons unsalted butter
• 1 medium onion, finely chopped
• 2 cloves garlic, minced
• 3 tablespoons all-purpose flour
• 1 ½ cups whole milk
• ½ cup heavy cream
• 1 teaspoon salt
• ½ teaspoon freshly ground black pepper
• 1 teaspoon fresh thyme, chopped (or ½ teaspoon dried thyme)
• 1 cup shredded sharp cheddar cheese
• 1 cup crushed saltine crackers
• 2 tablespoons grated Parmesan cheese
• 2 tablespoons fresh parsley, chopped (optional garnish)

Equipment

• Large mixing bowl for combining ingredients
• Medium saucepan to make the sauce
• Baking dish (9×13-inch recommended)
• Wooden spoon or spatula for stirring
• Measuring cups and spoons
• Knife and cutting board for prepping vegetables and herbs
• Oven mitts for safe handling

Instructions

1. Preheat your oven to 350°F (175°C). Lightly butter or grease your 9×13-inch baking dish to prevent sticking.
2. Shuck the oysters carefully, reserving their liquor. Strain the oyster liquor through a fine sieve to remove any grit and set aside.
3. Melt the butter in a medium saucepan over medium heat. Add the finely chopped onion and sauté until translucent, about 4 minutes. Stir in the minced garlic and cook for another 1 minute until fragrant.
4. Whisk in the flour to make a roux. Cook for about 2 minutes, stirring constantly to avoid lumps and to remove the raw flour taste.
5. Gradually pour in the milk, cream, and reserved oyster liquor while whisking continuously. Bring the mixture to a gentle simmer, stirring often until the sauce thickens, about 5 minutes.
6. Season the sauce with salt, pepper, and thyme. Remove from heat and stir in the shredded cheddar cheese until melted and smooth.
7. In a large mixing bowl, combine the oysters with the cheese sauce. Gently fold to coat the oysters evenly.
8. Pour the oyster mixture into the prepared baking dish. Sprinkle the crushed saltine crackers evenly over the top, then dust with grated Parmesan cheese for extra flavor and crunch.
9. Bake uncovered for 30-35 minutes, or until the top is golden brown and bubbly around the edges.
10. Remove from the oven and let it cool for 5 minutes. Garnish with fresh parsley if desired and serve warm.

Tips & Variations

For the best flavor, use fresh, high-quality oysters. If fresh oysters aren’t available, canned oysters can be a convenient substitute, but reduce added salt accordingly.

You can customize this dish by adding a handful of cooked spinach or mushrooms to the sauce for extra earthiness. Some cooks like to mix in a splash of white wine or sherry in the sauce for a subtle depth of flavor.

If you prefer a lighter version, substitute half-and-half for the cream.

For a gluten-free option, use gluten-free flour blends and gluten-free crackers or crushed nuts for the topping. To add a spicy kick, sprinkle a pinch of cayenne pepper or hot sauce into the sauce mixture before baking.
