📖 Instructions

1. First things first, let's get that chicken ready. Take your boneless, skinless chicken breasts and pat them really dry with paper towels. This helps ensure a beautiful sear on the grill. If your chicken breasts are super thick (more than about 3/4 inch), place them between two pieces of plastic wrap and gently pound them to an even thickness using a meat mallet or a rolling pin. This ensures they cook evenly and stay juicy. You don't want any dry spots!
2. Now for the seasoning: Sprinkle both sides of the chicken generously with salt, freshly ground black pepper, and a dash of garlic powder. Don't be shy here; flavor is your friend. Set the chicken aside while you make the star of the show – the herb butter.
3. For the glorious herb butter, grab a small mixing bowl. Add your softened unsalted butter. Then, finely chop your fresh parsley, chives, and thyme. Remember, fresh herbs make all the difference here, so try not to skip them! Mince your garlic clove really well. Add all these lovely herbs and garlic to the butter, along with a pinch more salt and pepper. Use a fork to mash everything together until it's perfectly combined. It should look vibrant and smell amazing. You can even do this a day ahead and keep it in the fridge; just let it come to room temp before using.
4. Time to fire up the grill! Preheat your gas grill to a medium-high heat, aiming for about 400-450°F (200-230°C). If you're using a charcoal grill, arrange the coals for direct heat. Once hot, give those grates a good cleaning with a grill brush, then lightly oil them to prevent sticking. A little oil on a paper towel held by tongs works wonders here.
5. Carefully place the seasoned chicken breasts on the hot grill grates. Close the lid and cook for about 5-7 minutes per side. The exact time depends on the thickness of your chicken and the heat of your grill. You're looking for nice grill marks and for the chicken to cook through. Do not rush this part, even if you are starving! Undercooked chicken is not fun.
6. Here’s where the magic happens. During the last 2-3 minutes of grilling, open the lid and generously spread the herb butter over the top of each chicken breast. It will start to melt and seep into the chicken, creating an irresistible aroma and adding so much flavor and moisture. Flip the chicken once more for another minute to ensure the butter melts fully and gets a little char.
7. To check for doneness, insert an instant-read meat thermometer into the thickest part of a chicken breast. You're aiming for an internal temperature of 160°F (71°C). Remember, the temperature will rise a bit as it rests. If it's not quite there, give it a few more minutes, checking again.
8. Once cooked, transfer the grilled chicken breasts to a clean cutting board. Cover them loosely with aluminum foil (this is called 'tenting'). Let them rest for 5-10 minutes. This resting period is SO important; it allows the juices to redistribute throughout the meat, resulting in incredibly moist and tender chicken. Seriously, don't skip the rest!
9. Finally, remove the foil, slice your beautifully grilled chicken breasts if you like, or serve them whole with any remaining melted herb butter drizzled over the top. It pairs wonderfully with a fresh green salad, roasted vegetables, or some fluffy rice. Enjoy your masterpiece!
