Step-by-Step Instructions
- Prepare Cheese Sauce:
- In a saucepan over low heat combine heavy whipping cream cream of chicken soup and cubed Velveeta cheese. Stir constantly until cheese is completely melted and mixture is smooth and glossy. This is your flavor-packed base so be patient with low heat to avoid scorching
- Season the Cheese Sauce:
- Add Kinder's Seafood Blend Cajun seasoning garlic powder Accent and black pepper to your melted cheese sauce. Stir well until all seasonings are completely dissolved. Taste and adjust salt or seasoning as desired. This infuses every bite with savory depth
- Cook Macaroni:
- Boil macaroni noodles in salted water until just al dente. Drain thoroughly so you do not water down the sauce. Transfer noodles into a large buttered baking dish to prevent sticking later
- Sauté the Crawfish:
- Melt butter in a skillet over medium heat then add crawfish tails and a sprinkling of your seafood seasoning. Sauté for about two to three minutes just to warm through and coat in butter. Overcooking makes crawfish tough so watch closely. Remove from the skillet and set aside
- Warm the Crab:
- Add a touch more butter to the same skillet and gently warm lump crab meat sprinkling lightly with seafood seasoning. Only heat for one or two minutes. Set aside so crab stays tender
- Cook Shrimp:
- Pat the shrimp dry and season with seafood blend. Sauté quickly in butter in your skillet or cook in an air fryer until opaque and just firm. Avoid overcooking for best juicy texture
- Assemble the Casserole:
- Pour half of your hot cheese sauce over the cooked macaroni in the baking dish. Scatter a portion of shredded Colby Jack cheese over the top and stir so everything is coated and cheesy
- Add the Seafood:
- Evenly distribute sautéed crawfish tails warmed crab meat and cooked shrimp over the mac and cheese mixture making sure every scoop has a bit of seafood
- Top with More Cheese Sauce and Cheese:
- Pour the remaining cheese sauce on top followed by the rest of the shredded Colby Jack cheese. Garnish with any extra crawfish tails and chopped fresh parsley for color
- Bake to Perfection:
- Place in a preheated oven at 177 C or 350 F. Bake for ten to fifteen minutes until the cheese is melty and the top is turning golden brown. Serve piping hot to enjoy at its creamiest

I love the combination of sweet crab and sharp Colby Jack in every bite. Once during a family reunion we doubled the recipe and barely saved a scoop for lunch the next day. True Southern comfort food magic
Storage Tips
This casserole stores beautifully. Cool leftovers quickly and wrap the baking dish tightly with foil or transfer to airtight containers. Refrigerate and enjoy within three days for best taste. Reheat in the oven covered at a low temperature to keep things creamy
Ingredient Substitutions
You can swap out seafood based on what is available. Lobster chunks work wonders if crab or crawfish are unavailable and scallops are an excellent addition too. Monterey Jack cheese can stand in for Colby Jack. For a lighter version use half and half in place of heavy cream though it will be less rich
Serving Suggestions
This bake is hearty enough to be the main attraction. I like to pair it with a crisp green salad and hot garlic bread to balance the richness. Add a side of roasted asparagus or sautéed green beans for festive dinners

Cultural and Historical Context
Seafood mac and cheese became popular in Gulf Coast states where shellfish is abundant and Southern families know how to turn a party casserole into an event. This version nods to classic Louisiana flavors with crawfish and Cajun spice
