Preheat the oven to 375°F. Season both sides of the pork chops with salt, pepper and paprika. Cover with plastic wrap and place back in the refrigerator.
Heat up a large skillet and melt 2 tablespoons of the butter. Add in the onions and a pinch of salt and reduce the heat to low. Cook the onions down for about 30-35 minutes until they are a rich amber color and jammy in consistency. Add in the minced garlic in the last minute.
Add in the white wine and deglaze the skillet. Let this simmer for a couple of minutes.
Pour in the beef broth, thyme and Dijon mustard. Mix well and simmer for about 3-4 minutes. The sauce should thicken a little bit. Remove the onion mixture from the skillet and set aside.
In the same skillet, over medium-high heat, melt the remaining butter and sear the pork chops for about 1-2 minutes per side.
Place the onions back into the skillet around and over the pork chops. Add the Gruyère cheese over each chop and place in the oven for 8-10 minutes until the cheese has fully melted.
Serve the pork chops with more onions and spoon the delicious sauce over.
Notes
Caramelizing takes patience. Stir about every 5 minutes and make sure the burner is on low.
Check the internal temperature of the pork to make sure it reaches a safe 145°F.
