01 - In a large skillet or Dutch oven, heat the vegetable oil over medium-high heat.
02 - Add the ground beef and cook until browned, breaking it up with a spoon (about 5 minutes). Drain excess fat if necessary.
03 - Add the chopped onion, celery, and green bell pepper. Sauté for 4–5 minutes until vegetables are softened.
04 - Stir in the minced garlic and cook for 1 minute until fragrant.
05 - Sprinkle in the Cajun seasoning, smoked paprika, thyme, oregano, salt, and pepper. Stir well to coat the mixture evenly.

07 - Pour in the chicken broth, scraping up any browned bits from the bottom. Bring to a boil.
08 - Reduce heat to low, cover, and simmer for 18–20 minutes, or until rice is tender and liquid is absorbed.
09 - Remove from heat and let sit, covered, for 5 minutes. Fluff with a fork.
10 - Garnish with chopped parsley and sliced spring onions before serving.
