Instructions

1. Prepare shrimp by tossing 2 pounds of peeled shrimp with 2 tablespoons olive oil, 1 tablespoon Cajun seasoning, salt, and pepper until evenly coated.

5. Combine cooked pasta with 2 pounds crab meat and ¼ cup basil in a large mixing bowl.

Notes

• Check shrimp carefully to ensure they cook evenly and don’t become rubbery by stirring constantly during the 4-6 minute cooking time.
• Use fresh crab meat if possible for the richest flavor, and drain it well to prevent excess moisture in the mac and cheese.
• Grate cheese fresh instead of using pre-shredded varieties for a smoother, more melted texture in the sauce.
• Let the mac and cheese rest after baking to allow the cheesy sauce to set and make serving easier, preventing a runny consistency.
