Crab Casserole

• 12 cup unsalted butter
• 14 cup finely chopped sweet onion
• 12 lb sliced white mushroom
• 13 cup unbleached all-purpose flour
• 1 teaspoon Old Bay Seasoning
• 3 cups milk
• 1 tablespoon cream sherry
• 1 teaspoon Worcestershire sauce
• 1 12 cups finely shredded swiss cheese (Gruyere)
• 1 lb lump crabmeat, picked over for shells and cartilage
• salt
• fresh ground black pepper
• 2 cups cooked rice
• 1 cup crushed buttery cracker crumb (such as Ritz)
• 12 cup finely grated parmesan cheese
• 1 tablespoon finely chopped fresh flat-leaf parsley
• 2 tablespoons pure olive oil

1. Melt the butter in a medium saute pan over medium heat; add in onion; saute for 2 minutes, until onion is softened.
2. Add in mushrooms; saute until mushroom liquid is absorbed and the mushrooms begin to color, 5-7 minutes.
3. Sprinkle the flour and Old Bay seasoning over the vegetables; cook, stirring to cook the flour, for about 2 minutes.
4. Slowly add in the milk, scraping up any bits stuck to the bottom of the pan, and bring the sauce to a boil.
5. Add in the sherry and Worcestershire sauce; stir to blend.
6. Remove the pan from heat and add the cheese a little at a time, stirring until all the cheese is melted.
7. Fold in the crabmeat, being careful not to break up the lumps; season with salt and pepper.
8. Coat the bottom of a 2 quart casserole dish with nonstick cooking spray.
9. Stir about 1 cup of the crab mixture into the rice, and line the bottom of the casserole with the rice.
10. Top with the remaining crab mixture.
11. Preheat oven to 350; in a small bowl, stir together the cracker crumbs, Parmesan cheese, and parsley.
12. Toss with the oil until moist; sprinkle the crumbs over the casserole and bake for 25-30 minutes, until bubbling and the topping is golden; let rest for 5 minutes before serving hot.
