Dredge each chop in the flour; shake of the excess and reserve the remaining flour.
1/2 cup all-purpose flour
Heat olive oil and butter in a large skillet over medium heat.
1 tbsp unsalted butter
Fry the pork chops in a single layer on each side until golden brown, about 3-4 minutes per side or longer until the internal temperature reaches 150℉.
Remove the chops from the pan and tent with foil to keep warm.
For the Gravy
In the same pan, heat 1 tbsp butter over medium heat. Add in sliced onions with a pinch of salt. Cook while occasionally stirring until soft and caramelized, about 5 minutes.
1 tbsp unsalted butter, 1 large yellow onion, 1 pinch kosher salt
Add the garlic and thyme, sauté until fragrant. Add 2 tbsp of the reserved flour to the pan. Mix the flour into the onions and cook for about 2 minutes.
4 clove garlic, 1 tsp fresh thyme
Pour in the chicken stock, scraping up the browned bits from the bottom of the pan (the fond). Let the liquid reduce and thicken slightly, about 2 minutes. Whisk in the buttermilk and simmer until thickened.
1/2 cup chicken stock, 3/4 cup buttermilk
Return the pork chops to the pan. Coat them in the sauce and let simmer until the pork is completely cooked through, about 5 minutes.
Garnish with the chopped parsley and serve warm.
1 tbsp fresh flat-leaf parsley
Notes
Serve with mashed potatoes covered with gravy and corn or green beans for a traditional Southern 'brown meal'. Mmm good!
