📖 Instructions

1. Prepare the Chicken: First thing first, grab your chicken breasts. If they're thick (like, over an inch at the thickest part), you'll want to butterfly them or slice them horizontally through the middle to make two thinner cutlets. This helps them cook more evenly and quicker. Pat them super dry with paper towels—this is a secret for that beautiful golden-brown sear, don't skip it!
2. Season the Chicken: Lay your dry chicken breasts on a clean plate or cutting board. Sprinkle both sides generously with salt and freshly ground black pepper. Don't be shy here; proper seasoning makes all the difference!
3. Heat the Skillet: Place a large cast iron or heavy-bottomed skillet over medium-high heat. Add 1 tablespoon of olive oil. Let it get nice and hot; you want to see a slight shimmer on the oil before adding the chicken.
4. Sear the Chicken: Carefully place the seasoned chicken breasts into the hot skillet. Make sure not to overcrowd the pan—if you have more than two breasts, cook them in batches. Sear for 5-7 minutes on one side, until they develop a deep, golden-brown crust.
5. Flip and Finish: Flip the chicken breasts over and reduce the heat to medium. Cook for another 5-7 minutes on the second side, or until they're cooked through. The internal temperature should reach 165°F (74°C). If you don't have a thermometer, cut into the thickest part of one piece; the juices should run clear.
6. Remove Chicken and Deglaze: Once cooked, transfer the chicken to a clean plate, tent it loosely with foil, and let it rest while you make the sauce. Don't clean that pan just yet—all those browned bits at the bottom are pure flavor!
7. Start the Sauce: Reduce the heat to low-medium. Add the remaining 1 tablespoon of olive oil (if using 1X) and the minced garlic to the skillet. Sauté for about 30 seconds to 1 minute, just until the garlic is fragrant and lightly golden, being careful not to burn it.
8. Add Liquids: Pour in the chicken broth and fresh lemon juice. Use a wooden spoon or spatula to scrape up all those delicious brown bits from the bottom of the pan—that's called deglazing, and it's where much of the sauce's depth comes from.
9. Simmer and Thicken: Bring the sauce to a gentle simmer and let it reduce for 3-5 minutes, or until it has slightly thickened. You want it to coat the back of a spoon.
10. Finish the Sauce: Remove the skillet from the heat. Stir in the cold butter (if using) and lemon zest until the butter is melted and the sauce is smooth and glossy. Taste the sauce and adjust seasoning if needed – maybe a pinch more salt or a tiny squeeze of lemon.
11. Serve: Return the rested chicken breasts to the skillet, spooning that glorious lemon sauce all over them. Garnish with fresh chopped parsley. Serve immediately with your favorite sides and prepare for happy sighs!
