Season the chops with salt and pepper. Dredge them lightly in the flour, shaking off any excess. Heat the oil and 1 Tbs. of the butter in a large skillet over medium-high heat. Sear the chops, turning once, until just lightly browned, about 2 minutes per side; transfer to a plate. Add the remaining butter to the pan, along with the onion; cook, stirring, until the onion is barely tender and golden, 3 to 4 minutes.
Add the vermouth and 1/4 cup water. Simmer until the liquid is reduced to about 1/4 cup, about 3 minutes. Stir in the bouillon cube and capers. Return the chops to the pan, settling them into the onions. Reduce the heat to a gentle simmer and cover tightly with a lid or foil. After 1 minute, check to see that the liquid is at a slow simmer; adjust the heat as needed. Continue to cook for another 7 minutes, turn the chops, and cook until just barely pink inside and firm to the touch (145° to 155°F), another 4 to 5 minutes.
Transfer the chops to a plate and cover loosely. Turn the heat to high, bring the liquid to a boil, stir, and add the cream. Boil, stirring occasionally, until reduced by about half to a saucy consistency, 1 to 2 minutes. Taste for salt and pepper. Stir any accumulated pork juices into the sauce. Serve the chops topped with the sauce and sprinkled with the parsley.
Serve with buttered egg noodles.
