Crawfish Etouffée

This classic crawfish etouffée brings the rich, savoury flavours of Louisiana to your kitchen in a lighter, diabetes-friendly format. By using a simple cornflour slurry rather than a traditional heavy roux, this dish achieves a beautifully thick and glossy sauce while remaining mindful of nutritional balance. The combination of the 'holy trinity'—onions, peppers and celery—provides a fragrant, aromatic base that perfectly complements the delicate sweetness of the tender crawfish tails.

Ideal for a comforting mid-week supper or a relaxed weekend dinner with guests, this seafood dish is both nutritious and deeply satisfying. Serve it over a small portion of steamed basmati or brown rice to soak up the spiced gravy. Bursting with fresh parsley and spring onions, it offers a vibrant, homemade alternative to heavier stews, proving that heart-healthy cooking never needs to compromise on authentic flavour.

Ingredients for Crawfish Etouffée

  • 900g peeled crawfish tails

  • 1 stick (8 tablespoons ) butter

  • 450g chopped onions

  • 100g chopped green peppers

  • 120ml chopped celery

  • 1 tablespoon cornflour

  • 240ml water

  • Salt and cayenne pepper, to taste

  • 50g chopped spring onions

  • 1/4 cup chopped fresh parsley

How to make Crawfish Etouffée

Melt the butter in a large saucepan over medium heat. Add the onions, peppers, and celery and cook, stirring, until the vegetables are soft and golden, 8 to 10 minutes. Add the crawfish tails and cook, stirring occasionally, until they throw off some of their liquid, 6 to 8 minutes.

Dissolve the cornflour in the water and add to the crawfish mixture. Simmer, stirring occasionally, until the mixture thickens, 4 to 5 minutes. Season with salt and cayenne.

Serve immediately over steamed rice. Garnish with a sprinkling of spring onions and parsley.
