Crawfish Gravy

This aromatic crawfish gravy is a deep, savoury celebration of Cajun-inspired flavours. Building a rich base from a slow-cooked roux and smoky bacon fat, the dish combines the traditional 'holy trinity' of onions, peppers, and celery with a gentle heat from jalapeños. It is a wonderfully comforting seafood dish that delivers a complex depth of flavour without the need for dairy, making it an excellent choice for those seeking a satisfying yet inclusive meal.

Perfect for a hearty weekend lunch or a midweek treat, this versatile recipe works just as well with coarsely chopped prawns if crawfish tails are difficult to source. Serve it generously over steaming white rice or with crusty bread to soak up every drop of the thick, spiced sauce. This homemade classic is a fantastic way to bring a taste of Southern soul food into your British kitchen.

How to make Crawfish Gravy

Cook bacon in a cast-iron or other large heavy skillet over medium heat until fat is rendered and bacon is crisp, about 12 minutes. Using a slotted spoon, transfer to paper towels to drain. Pour drippings into a small bowl; return 90ml to the same skillet set over medium heat. Whisk flour into drippings, reduce heat to low, and cook, whisking constantly, until roux is one shade darker than peanut butter, about 10 minutes.

Add onion, pepper, celery, jalapeños, and garlic; cook, stirring frequently, until onion is soft, about 20 minutes. Increase heat to medium-high; stir in reserved bacon, spice mix, then broth. Simmer, stirring often, until thickened and flavours meld, 20-25 minutes.

Stir in crawfish. Simmer until the tails curl, about 3 minutes. Season with salt, pepper, and cayenne, if desired. Garnish with spring onions.
