If you can melt butter, you can make this crawfish scampi, cher.
This is Louisiana's answer to shrimp scampi — same garlic butter luxury, but we use sweet little crawfish tails instead. It takes 10 minutes, one pan, and tastes like you spent all day.
I make it when I have a bag of crawfish tail meat in the freezer and PawPaw wants something fast over rice. No fancy wine sauce, no heavy cream. Just butter, garlic, green onions, and a squeeze of lemon with a little Tabasco kick. The trick is to NOT overcook the crawfish — they're already cooked, you're just warming them through.
Spoon it over white rice like we do down the bayou, toss it with pasta for date night, or pile it on toasted French bread for the best garlic bread you ever had.

Ingredients
1 pound pre-cooked, peeled crawfish tail meat, thawed if frozen, drained well
1/2 stick unsalted butter
3 cloves garlic, minced fine
1/4 cup chopped green onions, whites and greens
1 tablespoon parsley
1 teaspoon Cajun seasoning — Zatarain's or Tony's
1 teaspoon fresh lemon juice
Hot sauce, salt, and black pepper, to taste
Optional for serving: cooked white rice, linguine, or crusty garlic bread
Instructions
Step 1: Melt the butter. Place a large sauté pan over low to medium heat and melt the butter. Do not brown it — if it starts popping, turn it down.
Step 2: Sauté aromatics. Add the minced garlic — a garlic press gets it fine and even every time — and cook about 30 seconds until fragrant. You should smell it, but don't let it brown or it turns bitter. Toss in the green onions and stir.
Step 3: Add the crawfish. Gently fold the crawfish tails into the butter mixture. Cook 1–2 minutes just until hot through. Do not overcook, or the meat will get tough and rubbery — they'll curl a little, that's how you know they're done.
Step 4: Season. Remove the pan from the heat. Stir in the Cajun seasoning, parsley, lemon juice, hot sauce, salt, and pepper. Taste, and add more lemon or Tabasco if you like.
Step 5: Serve. Spoon the warm crawfish and all that garlic butter right over cooked white rice, pasta, or crusty garlic bread. Make sure you drizzle the pan sauce — that's the best part.
Nana's Kitchen Tips: Crawfish Scampi Rules
Drain them good. If using frozen tail meat, thaw it in the fridge overnight, then pour it in a colander and pat it bone-dry with paper towels. Wet crawfish makes watery scampi and the butter won't cling. If it smells a little river-y, give it a quick rinse and drain again.
Garlic is 30 seconds, not 3 minutes. Minced garlic burns fast in butter — 30 seconds till you smell it, then add your green onions. Burned garlic makes the whole pan bitter and you can't fix it.
Do not overcook, sha. This is the number one mistake. Crawfish tail meat from the bag is already cooked — you're just warming it in butter. 1 to 2 minutes max. If it shrinks, you cooked it too long.
Off the heat for seasoning. Take the pan off the burner before adding the Cajun seasoning, parsley, and lemon. The residual heat wakes up the spices without burning them, and the parsley stays bright green.
Butter, not margarine. Margarine separates and makes it greasy. Use real unsalted butter so you control the salt. If you only have salted butter, skip the extra salt until you taste it.
How to Serve & Store
Over rice: Classic Louisiana way — fluffy white rice soaks up the butter.
Over pasta: Toss with 8 oz linguine or angel hair. Add a splash of pasta water to make it silky.
As garlic bread: Spoon over toasted French bread slices for a quick appetizer — my favorite for game day.
To store: Cool completely, then store in an airtight container in the fridge up to 2 days. This does NOT freeze well — the butter sauce breaks and the crawfish get rubbery when you reheat.
To reheat: Warm gently in a skillet over low heat with a little extra butter. Do not microwave on high, or you'll get tough crawfish — 50% power, 30 seconds at a time.
Frequently Asked Questions
Can I use frozen crawfish tails?
Yes, cher, that's what most of us use outside of season. Thaw overnight in the fridge, drain very well, and pat dry. Look for Louisiana crawfish, not imported.
Can I use shrimp instead?
You can — use 1 lb small shrimp, peeled. If they're raw, cook 2–3 minutes until pink before adding the seasonings.
Is this spicy?
Not unless you make it. The Cajun seasoning has a little heat, and a few dashes of Tabasco go in at the end. Start with less, taste, then add more.
Can I add wine like regular scampi?
You can add 2 Tbsp white wine after the garlic, let it cook down 30 seconds, then add the butter. Nana likes it without — keeps it pure butter and garlic — but it's good both ways.
What if I don't have green onions?
Use 2 Tbsp minced shallot with the garlic, and add extra parsley at the end. Green onions are traditional, though.
How To Say It Like a Cajun: Crawfish!
If it pinches your fingers and steals your mudbugs, you're doing it Cajun, cher!
In my kitchen, it ain't ever "crayfish." That's what them Yankees call it. We say craw-fish — craw + fish, just like it looks.
Save this graphic and say it right next time you're at the boil!

This is the recipe I make when I want people to think I fussed all day, and really I just melted some butter. Ten minutes, one pan, and PawPaw thinks I'm a genius every time.
