If the chicken breasts are unevenly thick, pound them down so they’re roughly all the same thickness.

Sprinkle both sides of each chicken breasts lightly with the salt and pepper. In a large ovenproof skillet, heat the oil over medium high heat. Add the chicken and cook for 7-8 minutes, turning once halfway. You want the chicken nice and browned on the outside, but not fully cooked in the centers because they will finish in the oven. Set chicken on a plate and cover tightly with foil until step 5.

Preheat oven to 375°F (190°C).

Remove skillet from the stove and add the broth, lemon juice, lemon zest, onion, garlic, and thyme. Return skillet to the stove over medium high heat. Cook and stir to scrape up the browned bits from the bottom of the skillet. Bring to a boil. Allow to boil, uncovered, for 10 minutes or until the liquid is reduced to around 1/2 cup (120ml). Stir in the cream and butter. Bring to simmer, stirring occasionally, and allow to simmer for 3-4 minutes.

Add chicken to the sauce and place the skillet in the preheated oven. Bake until the chicken is fully cooked through, about 10 minutes. (Chicken is considered done when an instant read thermometer reads the center of the thickest part as at least 165°F (74°C).)

Serve chicken with sauce spooned on top and any of the listed optional garnishes. Leftovers keep well in the refrigerator for a few days. Reheat to your liking.
