Heat the olive oil in a large pot over medium heat. Once hot, add the sliced Andouille sausage and sauté for about 5-7 minutes, or until browned. Remove the sausage from the pot and set aside.
In the same pot, add the chopped onion, diced bell pepper, and diced celery. Sauté for approximately 5 minutes until the vegetables soften and the onions become translucent.
Add the minced garlic to the pot and cook for an additional minute, stirring frequently until the garlic is fragrant but not browned.
Pour in the diced tomatoes (including the juices), chicken broth, and sprinkle in the Cajun seasoning, thyme, and oregano. Stir well to combine all the ingredients thoroughly.
Increase the heat and bring the mixture to a rolling boil. Once boiling, add the rinsed rice and return the browned sausage to the pot. Stir gently, reduce the heat to low, cover the pot, and let it simmer for 20-25 minutes until the rice is tender and has absorbed most of the liquid.
While the rice cooks, season the shrimp with salt and pepper. In a separate skillet over medium-high heat, sauté the shrimp for 3-4 minutes until they turn opaque and pink. Remove from the heat promptly to avoid overcooking.
Once the rice is cooked, gently fold the sautéed shrimp into the jambalaya, ensuring an even distribution throughout the mixture. Cover the pot again and let it sit for 5 minutes to allow the flavors to meld beautifully.
Finally, use a fork to fluff the jambalaya gently before serving. Finish with a generous garnish of fresh chopped parsley.
