Crockpot Oniony Pork Chops with Creamy Mustard Sauce

This recipe is courtesy of recipezaar. It is wonderful and I highly recommend it. The sauce makes a lot, and I usually serve the sauce over mashed potatoes. So yummy.

1 Tbsp. vegetable oil
4-6 one-inch thick pork chops
2 onions, thinly sliced
4 cloves garlic, minced
1 tsp. dry mustard
1/2 tsp. salt
1 tsp. freshly ground black pepper
1 pinch cayenne pepper
2 Tbsp. all-purpose flour
1 Tbsp. cider vinegar
1/2 c. white wine
2 Tbsp. dijon mustard
1/2 c. whipping cream

Heat oil over medium-high heat in a skillet and brown pork chops on both sides. Place browned chops in the bottom of the slow cooker. In the same skillet, reduce heat to medium and saute onions until softened. Add the garlic, dry mustard, salt, pepper, and cayenne and cook for one minute. Add flour and cook, stirring for one minute. Add vinegar and wine and cook until thickened. Pour this mixture over pork chops and cook on low for 4-5 hours on low and 2-2.5 hours on high until the pork is tender. Remove pork chops from slow cooker and place on a warmed platter. Stir dijon mustard and whipping cream into the juices in slow cooker. When well combined, turn slow cooker off and pour the sauce over chops on platter and serve immediately.
