Step 1: Prepare the Pork Chops

1. Season the Chops: Pat the pork chops dry with paper towels and season both sides generously with salt and pepper.
2. Heat Olive Oil: In a large skillet over medium-high heat, add the olive oil. Once hot, add the pork chops and sear for about 4-5 minutes on each side until they are golden brown. Remove the chops from the skillet and set aside.

Step 2: Sauté the Onions and Garlic

1. Cook Onions: In the same skillet, add the sliced onion and cook for about 3-4 minutes until softened.
2. Add Garlic: Stir in the minced garlic and cook for an additional 30 seconds until fragrant.

Step 3: Make the Apple Cider Glaze

1. Add Cider and Seasonings: Pour in the apple cider, Dijon mustard, apple cider vinegar, thyme, and rosemary. Stir to combine and bring to a simmer.
2. Return Pork Chops: Return the seared pork chops to the skillet, spooning some of the glaze over the top.

Step 4: Simmer and Finish Cooking

1. Cover and Cook: Reduce the heat to low, cover the skillet, and let the pork chops simmer in the glaze for about 10-15 minutes, or until they reach an internal temperature of 145°F (63°C).
2. Optional Butter Finish: If desired, stir in a tablespoon of butter at the end for added richness and shine in the glaze.

Step 5: Serve

1. Plate and Drizzle: Serve the pork chops on plates, spooning the apple cider glaze and onions over the top.
2. Enjoy: Pair with your favorite sides, such as mashed potatoes or green beans.
