Wash, scrub, and dry the Russet potatoes thoroughly. Using a fork, poke small holes all over each potato to allow venting during cooking to prevent bursting.
02 -
Either wrap potatoes in foil and bake at 400°F for 40-50 minutes, or wrap individually in paper towels and microwave using the potato setting until tender.
03 -
Carefully cut a slit down the center of each potato without cutting through the bottom skin. Scoop out the insides into a bowl while reserving the skins intact.

Combine the potato flesh with softened cream cheese, chives or green onions, garlic powder, salt, and pepper. Mix well, then cover and keep warm.

In a bowl, toss shrimp and crawfish with 1 tablespoon each of Cajun seasoning, onion powder, and liquid crab boil. Set aside.

In a saucepan, melt 4 tablespoons of butter and sauté minced garlic for 30 seconds. Add the seasoned shrimp and crawfish and cook until shrimp turn opaque, around 4-5 minutes. Remove seafood and reserve the liquid left in the pan.
07 -
In the same saucepan, melt remaining butter, then whisk in flour until no lumps remain, about 1 minute. Gradually pour in reserved seafood liquid, then whisk in half and half. Bring to a low simmer.
08 -
Stir in remaining 1 tablespoon each of Cajun seasoning and onion powder. When the sauce begins to thicken, add all remaining cheeses and stir until melted.

Return cooked shrimp and crawfish to the sauce and stir to combine. Heat through and remove from heat.
