Step-by-Step Instructions
Prepare Ingredients
Finely chop shallot, red bell pepper, green onions, and parsley. Mince garlic. Grate parmesan cheese. Bring a large pot of salted water to a boil.
Sauté Aromatics
Heat olive oil and butter in a large skillet over medium heat. Add shallot, red bell pepper, and half the green onions with a pinch of salt. Sauté 8 minutes until softened. Add minced garlic and cook 1 minute more.
Make the Sauce
Add crawfish tails, heavy cream, grated parmesan, parsley, and Cajun seasoning. Stir to combine. Bring to a simmer, then reduce heat to low. Simmer 10–15 minutes until sauce thickens.
Cook the Pasta
While sauce simmers, cook rotini to al dente according to package directions. Reserve ½ cup pasta water, then drain.
Combine and Finish
Add drained pasta to the sauce along with a splash of reserved pasta water and remaining green onions. Toss to coat and simmer 1–2 minutes. Taste and adjust seasoning with more Cajun seasoning, salt, or pepper.
Serve
Serve hot, ideally with garlic bread on the side.

Crawfish Tough – Avoid overcooking; add them gently and simmer carefully.
Why This Recipe Works
Sautéing the holy trinity-inspired aromatics in butter and oil builds a flavorful foundation, while the rendered fat from crawfish tails enriches the sauce naturally. Heavy cream and parmesan create a stable, velvety emulsion that clings to the pasta, and the reserved pasta water helps achieve the perfect silky texture. Cajun seasoning blooms during simmering, infusing the entire dish with signature Louisiana heat and depth. The result is a cohesive, comforting pasta with balanced richness and spice at approximately 926 calories per serving.
