- 1 teaspoon Old Bay seasonings
- 2 cups milk

👩🍳 Instructions
Preheat the oven to 375 degrees F.
Follow the instructions on the package to cook the macaroni in a pot, then rinse under cold water.
Heat a skillet on the stove and add a tablespoon of butter.
Let it melt and then add the shrimp and Old Bay seasoning. Add Cajun seasoning too if liked. Cook for 3 minutes or until cooked through.
Add the crab and stir, then take the mixture off the heat.
Heat another skillet on the stove and melt 4 tablespoons of butter in there.
Whisk in the flour, bit by bit, to make a roux. When it’s combined, mix in the milk and cream.
Add half the cheese (plus the cream cheese if using) and keep stirring until most of it is melted.
Stir in salt, pepper and onion powder, then taste and adjust the seasonings if necessary.
Put the cooked pasta in the pot you cooked it in, drizzle the cheese sauce on top and stir.
Stir in the seafood as well as the butter sauce from the seafood and season again if necessary.
Grease a 13 x 9-inch baking pan with nonstick spray.
Add half the pasta and half the cheese on top, then repeat with the remaining pasta and remaining cheese.
Bake for about half an hour or until the cheese has melted and is bubbling.
Keep cooking or broil if you want a golden crust on top.
Cool for 15 minutes before serving.
