In a large plastic or glass container, stir water, salt, and brown sugar together until salt and sugar are dissolved. Add 15 sprigs thyme, 2 cloves garlic, and pork chops to liquid. Cover and refrigerate for 4 to 6 hours before cooking.
Remove pork chops from brine, and pat dry with a paper towel. Season evenly on both sides with pepper. Set aside.
Heat a large cast-iron skillet over medium-high heat. Add oil to skillet. Working in batches, cook pork chops until golden brown on both sides and a meat thermometer registers 140°, approximately 5 to 6 minutes per side.
During the last few minutes of cooking, add butter, remaining 10 sprigs thyme, and remaining 2 cloves garlic to skillet, continually basting chops.
Transfer cooked chops to a plate tented with aluminum foil. Let rest for at least 10 minutes before serving. Serve with Peach Chutney, if desired.
