Sprinkle both sides of the chops with kosher salt and ground black pepper and let sit for about 15 minutes. Combine the ingredients for the dredge.
Heat the vegetable oil in a Dutch oven over medium-high heat.
Dredge the pork chops in the dredge mix and shake off the excess.
When the oil is hot, sear the pork chops for about 4 minutes on each. Set aside. Do this in batches so you don't crowd the pan.
Make the Gravy
If there is excess oil left in the Dutch oven, wipe out with a paper towel.
Set the heat to medium over under the Dutch oven and add the butter.
When the butter is frothy add the AP flour and stir constantly to make a light roux. NOTE: The roux will be thin, but with the long cook, it will still serve to thicken the gravy.
Add the yellow onions and stir until starting to wilt about 8 to 10 minutes.
If using the mushroom, add them about halfway through (after about 4 minutes) sauteeing the onions.
When the onions are wilted, add the garlic and the Herb and Spice Blend. Saute, stirring constantly, until the garlic is aromatic, which will only take about 2-3 minutes.
Increase heat to medium-high.
Stir in the white wine and simmer until the wine has reduced by about half, about 5 minutes. Use the wine to deglaze the pan if necessary by scraping the bits of food off the bottom.
Add the stock, mix well. Bring the stock to a high simmer and continue for about 5 minutes.
Smother the pork chops
Add the pork chops along with the accumulated juices back to the Dutch oven. Stir and move them around so that they are all covered with the gravy.
Lower the heat to a low simmer, cover the Dutch oven and simmer for 1 hour. Stir the pot thoroughly every 15 minutes or so.
After 1 hour, continue to simmer with the pot partially covered for another 30 minutes to an hour or until the pork chops are very tender. Stir occasionally.
Check the pork chops for tenderness and continue to simmer until very tender. Taste the gravy for seasoning and add more if needed. Add more reserved stock if the gravy is too thick. Place the lid on completely or partially depending upon how thick you want the gravy.
Once the chops are tender and falling apart, let the pork chops rest for up to 10 minutes, then serve immediately over rice.
Notes
I developed this recipe using Le Bon Papa Creole Seasoning, a no-salt, no-MSG all-purpose Creole or Cajun Seasoning. Other sources of salt in this recipe are butter, stock, and the added kosher salt. Taste the gravy before adding more. Leftovers can be held in the fridge for 3 to 4 days in an airtight container. Reheat in a saucepan over medium heat or the microwave until heated.Leftovers can be frozen for 2 to 3 months in an airtight container. To defrost, set the pork chops in the fridge overnight, or reheat from frozen in a large pan, covered, and set over low heat until warmed. This recipe uses a light roux. Use 1 or 2 tablespoons of AP flour and do not cook the roux more than 3 minutes. For the best flavor, use bone-in pork chops, but you can substitute boneless if you want.
