Step-by-Step Directions

Step 01

In a saucepan over low heat, combine heavy cream, cream of chicken soup, and cubed Velveeta. Stir continuously for about 10 minutes until cheese is fully melted and the sauce becomes smooth and creamy.

Step 02

Incorporate seafood seasoning, Cajun spice, garlic powder, optional Accent, and freshly ground black pepper into the cheese sauce. Stir thoroughly to ensure even distribution of flavors.

Step 03

Boil macaroni in salted water according to package instructions until al dente. Drain well and transfer to a buttered baking dish to prevent sticking.

Step 04

Melt 1 tablespoon butter in a skillet over medium heat. Add crawfish tails and a pinch of seafood seasoning; sauté for 2–3 minutes until warmed through. Remove from heat and set aside.

Step 05

Add a small amount of butter to the same skillet and gently warm crab meat for approximately 1 minute, seasoning lightly. Remove from heat and reserve.

Step 06

Season shrimp with seafood seasoning blend. Sauté in a hot skillet with a pat of butter or cook in an air fryer until opaque and just cooked through, approximately 2–3 minutes. Avoid overcooking to maintain juiciness.

Step 07

Pour half of the cheese sauce over the macaroni in the baking dish. Add half of the shredded Colby Jack cheese and stir gently to evenly coat the pasta.

Step 08

Evenly distribute sautéed crawfish tails, warm crab meat, and cooked shrimp over the coated macaroni, spacing ingredients to allow even baking.

Step 09

Pour remaining cheese sauce evenly over the seafood layer. Sprinkle the remaining Colby Jack cheese on top. Optionally, add extra crawfish tails and chopped parsley for color and presentation.

Step 10

Bake in a preheated oven at 350°F (175°C) for 10–15 minutes, or until cheese is bubbly and golden at the edges. Serve immediately while hot.

Helpful Hints

  1. To ensure the creamiest texture, shred your own cheese rather than using pre-shredded. Avoid overcooking seafood by adding it just before baking. Taste the cheese sauce prior to baking to adjust seasoning as needed.
  2. Allow to cool completely before refrigerating leftovers. Store covered for up to three days and reheat in an oven covered with foil or in the microwave for quick individual servings.
