Marinate the Chicken: Rinse and pat the chicken thighs dry. In a blender, combine cilantro, lemon zest and juice, lime juice, olive oil, oregano, paprika, garlic powder, onion powder, black pepper, and Creole seasoning. Blend until smooth. Pour this marinade over the chicken, ensuring it slides under the skin for maximum flavor. Cover and refrigerate at least 3 hours (overnight is best).

Roast the Chicken: Preheat oven to 350°F (175°C). Let chicken rest at room temperature for 15–20 minutes before baking. Arrange pieces skin-side up on a greased roasting pan. Roast 40–50 minutes, until juices run clear and internal temperature reaches 165°F (74°C). During the last 20 minutes, baste with its pan juices. For crispy golden perfection, broil for 5 minutes.

Prepare the Mashed Potatoes: Place peeled potato chunks in salted water. Bring to a boil; cook 15–20 minutes until fork-tender. Drain thoroughly. Return potatoes to the pot; add butter, cream, and seasonings. Mash until smooth and creamy.

Make the Cream Gravy: In a saucepan, melt butter and olive oil over medium heat. Whisk in flour to form a light roux; cook 1 minute. Slowly whisk in broth to prevent lumps. Stir as the mixture thickens. Add heavy cream, seasonings, and a dash of hot sauce. Simmer gently 5–7 minutes until glossy.

Serve and Enjoy: Place a scoop of mashed potatoes in the center of each plate. Lay a golden-brown chicken thigh on top. Generously drizzle with warm cream gravy. Garnish with chopped cilantro or parsley.
