Delicious Crab and Shrimp Casserole for a Perfect Dinner (Print version)

A creamy baked seafood casserole with shrimp, crab, pasta, cheese sauce, and a crisp panko topping.

# Ingredients:

For the casserole

01 - 8 oz (225 g) small pasta shells
02 - 3 tablespoons unsalted butter
03 - 1/2 cup finely diced yellow onion
04 - 1/2 cup finely diced celery
05 - 1/2 cup finely diced red bell pepper
06 - 3 cloves garlic, minced
07 - 3 tablespoons all-purpose flour
08 - 1 1/2 cups (360 ml) whole milk
09 - 1/2 cup (120 ml) half-and-half
10 - 1 teaspoon Old Bay seasoning
11 - 1/2 teaspoon smoked paprika
12 - 1/2 teaspoon kosher salt, plus more for pasta water
13 - 1/4 teaspoon black pepper
14 - 1 1/2 cups (170 g) shredded Monterey Jack cheese
15 - 1 lb (450 g) raw medium shrimp, peeled, deveined, and patted dry
16 - 8 oz (225 g) lump crab meat, picked over for shells
17 - 1 tablespoon fresh lemon juice
18 - 2 tablespoons chopped fresh parsley

For the topping

19 - 3/4 cup (45 g) panko breadcrumbs
20 - 2 tablespoons unsalted butter, melted
21 - 1/4 cup (25 g) grated parmesan cheese
22 - 1 tablespoon chopped fresh parsley

# Instructions:

01 - Heat the oven to 350°F. Grease a 9x13-inch baking dish. Boil the pasta in salted water for 1 minute less than the package says for al dente, then drain.
02 - Melt 3 tablespoons butter in a large skillet over medium heat. Add onion, celery, and bell pepper. Cook for 4-5 minutes until softened, then stir in garlic for 30 seconds.
03 - Sprinkle flour over the vegetables and stir for 1 minute. Slowly whisk in the milk and half-and-half. Cook for 3-4 minutes until the sauce lightly coats a spoon.
04 - Stir in Old Bay, smoked paprika, salt, pepper, and Monterey Jack. Keep the heat low and stir until the cheese melts smoothly.
05 - Add the shrimp, crab, lemon juice, parsley, and drained pasta. Fold gently so the crab stays in tender pieces.
06 - Transfer the mixture to the baking dish. Mix panko, melted butter, parmesan, and parsley, then sprinkle over the top. Bake for 20-25 minutes until bubbling and golden.
07 - Let the casserole stand for 5 minutes before scooping. Serve hot with lemon wedges if desired.

# Good to know:

01 - Use lump crab for the best texture, but claw meat works well in a casserole.
02 - If using cooked shrimp, fold it in with the crab and check the casserole after 15-18 minutes.
03 - Resting the casserole for 5 minutes helps the sauce settle before serving.
