Brown the Sausage: Heat the olive oil in a large stockpot or Dutch oven over medium-high heat. Once the oil shimmers and smells fragrant, add the sliced turkey sausage in a single layer. Cook for 4-5 minutes, undisturbed, until the bottoms are a deep, golden-brown colour and you hear a satisfying sizzle. Flip the pieces and cook for another 3 minutes until the other side is equally browned. Transfer the browned sausage to a plate using a slotted spoon, leaving the rendered fat in the pot.

Sauté the Holy Trinity: Reduce the heat to medium. Add the diced onion, celery, and green bell pepper to the pot. Stir them through the hot fat; you'll hear a gentle hiss. Cook for 6-8 minutes, stirring occasionally, until the vegetables have softened significantly and the onion becomes translucent. The kitchen will fill with a sweet, savoury aroma. Add the minced garlic and cook for a further minute, until it becomes fragrant.

Bloom the Spices: Sprinkle the Cajun seasoning, smoked paprika, dried thyme, and cayenne pepper (if using) over the softened vegetables. Stir vigorously for 30-60 seconds. The mixture will look dry and smell intensely spicy and smoky. This blooming step is crucial—it wakes up the spices and deepens their flavour.

Build the Broth: Pour in the can of diced tomatoes with their juices and the chicken stock. Use a wooden spoon to scrape up any browned bits stuck to the bottom of the pot—this is where the intense flavour lives. Drop in the bay leaves. Bring the liquid to a full, rolling boil; you'll see large bubbles breaking the surface.

Simmer the Soup: Once boiling, stir in the uncooked rice and return the browned turkey sausage to the pot. Reduce the heat to low, cover the pot with a lid slightly ajar, and let it simmer gently. You want a soft, quiet bubbling, not a vigorous boil. Cook for 18-20 minutes, stirring once halfway through. The rice will absorb the liquid and swell, and the soup will visibly thicken. The aroma will be deeply savoury and rich.

Finish and Serve: After 20 minutes, check the rice: it should be tender but still have a slight bite (al dente). Remove the pot from the heat and discard the bay leaves. Taste the broth—it should be savoury and gently spicy. Adjust the seasoning with salt and pepper. The soup will look hearty and slightly creamy from the rice starch. Ladle into bowls, garnish generously with fresh parsley, and serve immediately.
