Quick dry brine pork chops: Season pork chops with salt and pepper on both sides. Let them rest for 20 minutes (or alternatively season overnight, refrigerated). Use about ½ teaspoon of Kosher salt and a few grinds of pepper per pork chop. Tip: In this step, we are “quick dry-brining” the pork with salt. This will keep it juicy and tender.
Cook pork chops: In a large skillet, heat olive oil over medium heat. Cook the pork for about 5 minutes per side, or until it's 150ºF in the center (it will finish cooking later). Remove from pan and set aside. Note 1: Bone-in pork chops may take an extra 2-3 minutes to cook, especially around the bone. Note 2: Pork is safe at 145ºF, but I prefer mine a little over; feel free to adjust to taste.
Cook onions: In the same skillet (do not wipe clean), melt 2 tablespoons of the butter over medium heat. Cook the onions, stirring occasionally until softened, about 12 to 15 minutes. Add a splash of broth as needed to deglaze any brown bits. Tip: Try not to stir too frequently so that the onions have a chance to turn golden.
Add aromatics: Then, add the minced garlic, rosemary and thyme. Cook for another 1-2 minutes, stirring, until fragrant.
Build the pan sauce: Stir in the remaining 1 tablespoon of butter, dijon mustard, chicken broth, and the apple cider until incorporated. Scrape the brown bits with a wooden spoon. Bring to a simmer.
Add the apples and simmer for about 5 to 7 minutes, until softened but still crisp. Season with more salt and pepper to taste. At this point, the sauce should slightly thicken, but still be relatively thin. If needed, more liquid (equal parts broth and cider) until desired consistency.
Return the pork chops to the pan, nesting them under the apples. Simmer for another 2-3 minutes over medium-low heat to finish cooking. Serve immediately. Enjoy!
