Make caramelized onions if desired: Place the 2 teaspoons of olive oil into a large oven proof braising Dutch oven over medium heat. Add the sliced onions and cook, stirring often, for 20-30 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.
Heat a braising Dutch oven that is coated in cooking spray and 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. Cover with a tin foil tent.
Add the butter and the last teaspoon of oil to the Dutch oven and add the onions. Cook, stirring occasionally, for 5-6 minutes or until tender and golden brown; add the chili powder; cook stirring constantly for 1 minutes. Add the vinegar, maple syrup, water, Worcestershire sauce, and sea salt and freshly cracked pepper to taste. Stir well then add the pork chops back into the Dutch oven uncovered and place into the oven. Bake for 5-7 minutes or until the pork is cooked through. Remove from the oven.
Place the pork on a serving plate with a tin foil tent and let the meat rest for 5 minutes. If you prefer a thicker sauce, heat the sauce over medium high heat then whisk in the flour until well combined and thick. Drizzle the sauce over the pork chops then serve with the caramelized onions on the side. Enjoy.
