Seafood au Gratin — When the Roux Keeps Turning and Louisiana Calls

Week 399. Year 8. Tommy is 41. Fall. Hunting season approaching. The gumbo cravings starting. LSU football on the TV with Rémy on the couch arguing plays. Colette (15) in high school, painting. The season turning, the roux darkening, the days getting shorter in a way that makes the kitchen brighter by contrast.

Made smothered pork chops this week — the kind of food that fills the house with the smell of Louisiana and the knowledge that whoever walks through the door is walking into a home where the stove is on and the food is ready and the welcome is unconditional. The meal was the day. The day was the meal. Both were good. The roux keeps turning.

That smell of Louisiana in the kitchen — the roux darkening, the days shortening, the house filling up with something that says you’re home — that’s the feeling I chase every fall. Smothered pork chops had the house right that night, but when I want to push deeper into that Southern comfort zone, into something that could sit next to a gumbo on the stove and not apologize for itself, I reach for this Seafood au Gratin. It’s the kind of dish Colette stops painting for and Rémy pauses the game to ask about. Rich, creamy, unmistakably Louisiana — the roux keeps turning, and so does this recipe.

Seafood au Gratin

Prep Time: 20 min | Cook Time: 30 min | Total Time: 50 min | Servings: 6

Ingredients

• 1 lb medium shrimp, peeled and deveined
• 1 lb lump crab meat, picked over for shells
• 1/2 lb bay scallops
• 4 tbsp unsalted butter
• 1/2 cup yellow onion, finely diced
• 1/2 cup green bell pepper, finely diced
• 3 cloves garlic, minced
• 3 tbsp all-purpose flour
• 1 cup whole milk
• 1/2 cup heavy cream
• 1/2 cup dry white wine
• 1 tsp Creole seasoning
• 1/2 tsp smoked paprika
• 1/4 tsp cayenne pepper
• Salt and black pepper to taste
• 1 1/2 cups shredded Gruyère cheese, divided
• 1/2 cup shredded sharp cheddar cheese
• 1/4 cup seasoned breadcrumbs
• 2 tbsp fresh parsley, chopped

Instructions

1. Preheat and prep. Preheat your oven to 375°F. Lightly butter a 9x13-inch baking dish or six individual gratin dishes and set aside.
2. Sauté the aromatics. In a large skillet over medium heat, melt the butter. Add the onion and bell pepper and cook for 4–5 minutes until softened. Add the garlic and cook 1 minute more until fragrant.
3. Build the roux. Sprinkle the flour over the vegetables and stir constantly for 1–2 minutes until the mixture turns lightly golden and smells nutty. This is your base — don’t rush it.
4. Make the cream sauce. Slowly whisk in the white wine, then the milk and heavy cream, a little at a time, until the sauce is smooth. Bring to a gentle simmer and cook 3–4 minutes until thickened. Season with Creole seasoning, paprika, cayenne, salt, and black pepper.
5. Add the seafood. Stir in the shrimp, crab meat, and scallops. Cook just 2–3 minutes — enough to barely opaque the shrimp. Remove from heat.
6. Incorporate the cheese. Stir in 1 cup of the Gruyère and all of the cheddar until melted and combined. Pour the mixture into the prepared baking dish.
7. Top and bake. Mix the remaining 1/2 cup Gruyère with the breadcrumbs and scatter evenly over the top. Bake uncovered for 20–25 minutes until bubbling at the edges and golden brown on top.
8. Rest and serve. Let rest 5 minutes before serving. Scatter fresh parsley over the top and bring to the table directly from the dish.
