Instructions
- Prepare the Cheese Sauce:
- In a heavy saucepan over low heat combine heavy cream cream of chicken soup and cubed Velveeta cheese. Stir constantly as the cheese melts and transforms into a thick smooth sauce. Be patient and do not rush or the sauce can scorch. Scrape the bottom often.
- Season the Sauce:
- Once melty and cohesive whisk in the Kinder's Seafood Blend Cajun seasoning garlic powder Accent and ground black pepper. Keep whisking so seasonings dissolve and perfume the sauce deeply. Taste as you go and add more seasonings if you love extra boldness.
- Cook the Pasta:
- Bring a large pot of salted water to a rolling boil and add the macaroni noodles. Stir once or twice to keep pasta from sticking. Boil until just al dente the noodles will finish cooking in the oven. Drain very well and transfer to an extra-large baking dish spreading out gently.
- Sauté the Crawfish:
- Melt unsalted butter over medium heat in a nonstick skillet. Add the thawed crawfish tails. Sprinkle a little of the seafood blend over them. Sauté for two to three minutes until just heated through and fragrant being careful not to overcook.
- Warm the Crab:
- Add a dab of butter to the same skillet and gently warm the drained lump crab meat over low heat. A short toss is plenty to bring out its sweetness. Sprinkle with a touch of seafood seasoning if desired.
- Cook the Shrimp:
- Lightly season the peeled shrimp with seafood blend. Cook them in a skillet over medium heat with a dab of butter until they turn pink and opaque or air fry at 190 C for about five minutes. Avoid overcooking or the texture toughens.
- Combine Pasta and Sauce:
- Pour half of the finished cheese sauce over the drained macaroni in the baking dish. Add a generous handful of shredded Colby Jack cheese. Stir gently to ensure every noodle is coated and no dry patches remain.
- Layer in the Seafood:
- Arrange the crawfish tails lump crab and shrimp evenly across the cheesy macaroni base. Press some seafood deeper into the pasta so each scoop grabs a bit of everything.
- Top and Garnish:
- Pour the remaining cheese sauce over the whole dish then add the rest of the shredded Colby Jack cheese for a golden bubbly crust. Tuck in extra crawfish and a good pinch of fresh parsley.
- Bake Until Bubbling:
- Slide the baking dish into a preheated 177 C oven. Bake for ten to fifteen minutes just until the cheese is melted and the top begins to turn gold at the edges. Let rest a few minutes before serving for easier scooping.

I always look forward to adding crawfish as it is a nostalgic taste of summers with my cousins in Louisiana. Watching the cheese bubble and the aroma fill the house turns dinnertime into an event.
Storage Tips
Store leftovers in an airtight container in the fridge for up to three days. For best results reheat gently in the oven covered with foil to prevent drying. Add a splash of cream if the pasta feels stiff.
Ingredient Substitutions
If you cannot find crawfish tails substitute extra shrimp or scallops both pair beautifully with the cheese sauce. For less spice swap the Cajun blend with Old Bay or lemon pepper seasoning. You can use Monterey Jack or sharp Cheddar instead of Colby Jack.
