01 - Heat vegetable oil in a large skillet or Dutch oven over medium-high heat until shimmering.
02 - Add ground beef to the hot pan, breaking it apart with a wooden spoon. Cook for approximately 5 minutes until thoroughly browned. Drain excess fat if needed.
03 - Add chopped onion, celery, and green bell pepper to the beef. Sauté for 4 to 5 minutes until vegetables are softened and translucent.
04 - Stir in minced garlic and cook for 1 minute until fragrant, being careful not to burn it.
05 - Sprinkle Cajun seasoning, smoked paprika, dried thyme, dried oregano, salt, and black pepper over the meat and vegetables. Stir thoroughly to distribute spices evenly.
06 - Add uncooked rice to the skillet, stirring constantly for 2 minutes to lightly toast the grains and enhance flavor.
07 - Pour in chicken broth, using your spoon to scrape up any browned bits from the bottom of the pan. Bring the mixture to a rolling boil.
08 - Reduce heat to low, cover tightly, and simmer for 18 to 20 minutes until rice is tender and all liquid has been absorbed.
09 - Remove from heat and let stand, covered, for 5 minutes to allow rice to settle. Fluff gently with a fork before serving.
10 - Sprinkle with chopped fresh parsley and sliced spring onions. Serve hot as a main dish or alongside roasted meats and vegetables.
