Begin by patting your pork chops dry with paper towels. This helps achieve a nice sear. Season both sides generously with paprika, granulated onion, garlic powder, lemon black pepper, and salt.
In a large skillet, heat a tablespoon of olive oil over medium-high heat. Once the oil is shimmering, add the seasoned pork chops. Sear them for about 3-4 minutes on each side until golden brown. Remove the chops from the skillet and set them aside.
In the same skillet, add a bit more olive oil if needed. Toss in the sliced onion and minced garlic, sauté for about 5 minutes until the onions are soft and translucent.
Pour in the chicken broth, stirring to deglaze the pan and pick up any flavorful bits stuck to the bottom. Bring the mixture to a gentle simmer. Whisk in the Dijon mustard and sour cream until well combined.
Return the pork chops to the skillet, spooning some of the sauce over the top. Reduce the heat to low, cover the skillet, and let everything simmer for about 30-40 minutes.
Once the pork chops are cooked, taste the sauce and adjust the seasoning if necessary. For a finishing touch, garnish with fresh herbs like parsley or chives to add brightness and flavor.
Transfer the pork chops to plates and spoon the luscious mustard sauce over the top. This dish pairs wonderfully with a side of steamed vegetables, mashed potatoes, and fresh green salad.
