Creamy Chicken with Mashed Potatoes

Mash the boiled potatoes with the butter, cream, salt, and black pepper, mixing well until smooth and evenly combined with no visible lumps.

Season the chicken breasts with the onion powder, garlic powder, paprika, Cajun seasoning, salt, black pepper, lemon juice, and olive oil, tossing until evenly coated.

Heat the olive oil and butter in a large skillet over medium-high heat, then arrange the seasoned chicken in a single layer without overcrowding the pan.

Sear the chicken over medium-high heat, turning it once the underside is golden, until both sides are evenly browned.

Add the rosemary and garlic to the skillet over medium heat, stirring them through the hot fat around the chicken until fragrant but not burned.

Cover the skillet and cook the chicken with the herbs and garlic over medium-low heat until cooked through yet still tender and juicy.

Transfer the cooked chicken to a plate, leaving the fat and browned juices in the skillet to create a flavorful base for the sauce.

Add the mushrooms to the same skillet and sauté over medium-high heat until softened, most of their liquid has evaporated, and they begin to brown.

Add the minced garlic to the mushrooms over medium heat and sauté until fragrant without letting it brown or burn.

Add the all-purpose flour to the mushroom mixture over medium heat and stir well until lightly toasted with no raw flour remaining.

Pour in the chicken broth over medium heat, stirring and scraping the bottom of the skillet to release the browned bits, until the mixture is smooth.

Add the cream, salt, and black pepper over medium-low heat, stirring until fully combined and the sauce is smooth.

Let the mushroom sauce simmer over medium-low heat, stirring, until slightly thickened and able to coat the back of a spoon.

Return the chicken to the sauce and add the lemon juice and basil, then gently turn the chicken until coated in the sauce and heated through.

Spoon the mashed potatoes onto serving plates, place the chicken alongside them, and pour the creamy mushroom sauce over the chicken. Serve hot.
