Hint: When we have leftover crawfish tails like this it's because we have had a crawfish boil and the tails are deliciously seasoned. If you're using store-bought crawfish it won't be as well seasoned. You'll need to adjust this recipe and add more seasoning accordingly.

Once the Cajun crawfish casserole has cooled completely, cover with plastic wrap or aluminum foil and store in the refrigerator for up to 3 days.
Reheating in the microwave will be the best way to heat back up again.
Expert Tip: When reheating in the microwave, don't use too big a piece of casserole or the middle will take too long to warm up and the outer edges will overcook.
It can differ, but you're looking at crawfish tails, cheese, rice (or potato), onions etc, and seasoning.
You can. However, this recipe has been developed using tails leftover from a Louisiana Cajun Crawfish Boil - in other words, they're incredibly seasoned. You'll likely need to add more seasoning to adjust.

We use crawfish tails leftover from our crawfish boil, which means they are well seasoned. It's what I used in this recipe. If you find yourself using store-bought frozen crawfish tails I recommend adjusting the seasoning accordingly. You'll probably need more.
