Place the shrimp in a plate or bowl. Season with salt, pepper, and Creole seasoning. Toss to coat evenly and set aside.
Heat a heavy pot (skillet, Dutch oven, or another oven-safe pot) over medium heat. Add about 2 tablespoons of oil to the skillet.
Add the sausage and brown for a few minutes when the oil is hot. Then remove the sausage and set it on a plate.
Add the shrimp to the same pan and brown for 2-3 minutes. Then remove them and place them on the plate with the sausage.
Add more oil to the pan, then add the onions, celery, and bell pepper. Sauté for about 2-3 minutes, and then add garlic, thyme, and bay leaf. Continue cooking for 4-5 minutes.
Next, stir in the rice, crushed tomatoes, hot pepper sauce, and Worcestershire, followed by shrimp stock. Add Creole seasoning, salt, and pepper to taste.
Return the sausage to the pot. Bring it all to a boil before reducing the heat to barely a simmer. Cover and cook for about 15 minutes.
Next, add the shrimp on top of the jambalaya and gently stir it in.
Cover the jambalaya with a lid and continue cooking while occasionally stirring until the shrimp is pink and cooked through. It will take 4-5 minutes, depending on the size and thickness of the shrimp you use.
Finally, remove the dish from the heat, sprinkle it with green onions and parsley, and serve warm.
