In the same skillet you cooked the chicken in, melt the butter over medium heat. You’ll want to use the leftover bits of chicken in the pan, as that adds flavor to your sauce. Add the minced garlic and sauté for about 1 minute until fragrant. Be careful not to burn it—you just want to release the lovely garlic aroma without overcooking it.
Now, add the lemon zest and lemon juice to the pan. The bright, fresh citrus scent will hit you immediately, and it’s just amazing! Stir everything together and let it cook for a minute or two, allowing the lemon flavor to infuse the oil and butter.
Next, pour in the chicken broth and let it simmer for about 3-4 minutes. This helps the sauce reduce and intensify in flavor. Stir in the heavy cream and bring the mixture to a gentle simmer. Season with salt and pepper to taste, and let it cook for another 2-3 minutes until the sauce thickens and becomes creamy.
