Make the caramelized onions by placing the 1 tablespoon of oil into a large ovenproof braising Dutch oven over medium heat. Add the sliced onions and cook, stirring often, for 25-30 minutes, or until caramelized and golden brown. Season with sea salt, to taste. Side Note: If the skillet gets dry, add a tablespoon of water or two.
Remove from the Dutch oven and set aside.
Preheat the oven to 400 degrees.
Sear the pork by heating the same braising Dutch oven with the remaining tablespoon of oil over medium heat. Add the seasoned pork chops to the HOT pan. Cook for 3-4 minutes or until golden brown then flip; cook for 1-2 minutes then remove from the Dutch oven to a plate. Sear the fat cap of each chop for a few minutes, if desired. Cover with a foil tent.
Make the sauce by adding the butter to the same braising Dutch oven. Add the onions and cook, stirring occasionally, for 5-6 minutes or until tender and golden brown; add the chili powder, and cook stirring constantly for 1 minute.
Add the vinegar, maple syrup, water, Worcestershire sauce, sea salt, and freshly cracked pepper to taste.
Stir well then place the pork chops back into the braising Dutch oven uncovered and place into the oven.
Bake the pork for 5-7 minutes or until the pork is cooked through. Remove from the oven.
Place the pork on a serving plate with a foil tent and let the meat rest for 5 minutes.
Serve the pork by drizzling the sauce over the pork chops and serve with the caramelized onions on the side. Enjoy.
