Step‑by‑Step Instructions for Classic Cod Au Gratin

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (180°C). While the oven warms up, take your fresh cod loins and cut them into 1-inch pieces. Arrange these pieces evenly in an 8×8-inch baking pan or divide them among several ramekins for individual servings. This preparation not only sets the stage for baking but allows the cod to cook perfectly throughout.

Step 2: Sauté the Aromatics
In a medium saucepan, melt 4 tablespoons of butter over medium heat. Once melted, add one finely chopped small onion and two pressed garlic cloves, sautéing for about 3-4 minutes. Cook until the onions are translucent and fragrant, stirring occasionally to ensure even cooking. This step forms the aromatic base of your Classic Cod Au Gratin, enhancing the flavor profile.

Step 3: Make the Cheese Sauce
Sprinkle 2 tablespoons of corn starch into the pan with the onion and garlic, stirring for 1 minute to create a roux. Then, gradually whisk in 2 tablespoons of Dijon mustard and ¼ cup of dry white wine until smooth. Slowly add 2 cups of whole milk, whisking continuously for about 5 minutes or until the sauce thickens to a creamy consistency. This cheese sauce will envelop the cod, creating a rich, comforting layer.

Step 4: Add Cheese and Seasoning
Once the sauce has thickened, stir in half of the ½ cup shredded Parmesan cheese and a small handful of 1 cup shredded cheddar cheese. Mix until melted and smooth, then season the sauce with dried summer savory, salt, and pepper to taste. This step enhances the depth of flavors in your Classic Cod Au Gratin, making it irresistibly delicious.

Step 5: Combine and Coat
Pour the creamy cheese sauce over the prepared cod pieces, ensuring they are evenly coated with this luxurious mixture. Use a spatula to gently distribute the sauce, ensuring every piece of fish is submerged. The combination of tender cod and rich sauce forms the heart of this Classic Cod Au Gratin, preparing it for a delightful topping.

Step 6: Prepare the Topping
Sprinkle the remaining shredded cheddar and Parmesan cheese evenly over the top of the cod and sauce mixture. Then, generously crumble a layer of plain potato chips over the cheese for that perfect crunch. This contrast between creamy and crispy will crown your Classic Cod Au Gratin, enticing everyone at the table.

Step 7: Bake to Perfection
Place the baking pan in the preheated oven and bake uncovered for 35-50 minutes. If you’re using ramekins, aim for around 35 minutes, while the baking pan may take up to 50 minutes. Keep an eye out for a bubbly golden crust and ensure the fish is cooked through, achieving the ideal texture before removing it from the oven.

Step 8: Serve and Enjoy
Once baked to perfection, allow your Classic Cod Au Gratin to cool for a few minutes before serving. Enjoy this hearty dish hot, with leftovers refrigerable for up to three days. This comforting meal pairs wonderfully with steamed green vegetables or creamy mashed potatoes, making every bite a celebration of flavor.
