Seafood Mac-n-Cheese - Amy

1 lb elbow macaroni
6 Tbsp butter
1/2 medium onion, finely chopped
1 garlic clove, minced
1/3 C flour
3 C whole milk
1/8 tsp ground nutmeg
Salt and pepper
1 lb chopped seafood (this can be anything, like lobster, crab, shrimp or crawfish)** 
4 C (1 lb) mixed grated cheeses such as Parmesan, cheddar, Swiss and fontina
1/2 C Panko Breadcrumbs
1/3 tsp Creole seasoning (I make my own, a combination of garlic powder, paprika and thyme)

Preheat oven to 400 degrees. In a large pot of boiling water, cook macaroni 2 minutes less than al dente. Drain; rinse with cold water. Set aside.
While pasta is cooking, melt butter over medium in a large saucepan. Transfer 2 tbsp melted butter to a medium bowl and reserve. Add onion and garlic to pan; cook until softened, 3 to 5 minutes.  Add flour; cook, stirring 1 minute. Add milk; whisk until smooth. Bring to a boil; reduce to a simmer, and cook until sauce has thickened, 2 to 3 minutes. Season with 3/4 tsp salt, 1/2 tsp pepper and nutmeg.

Remove pan from heat. Fold in seafood, macaroni, and cheese; transfer to a shallow 4 quart baking dish. Put reserved melted butter in a bowl, add breadcrumbs and Creole seasoning; toss, and scatter over macaroni mixture. Place baking dish on a rimmed baking sheet. Bake until topping is golden and sauce is bubbling, 15-20 minutes. Let cool 5 minutes before serving.

**I usually do crab or shrimp or a combo of both. Lobster is a little too pricey and fancy for my family, although it would be SO GOOD.
