In a large saucepan, heat the canola oil and saute the chopped onions until softened. Season with salt, pepper and thyme. Transfer the onions to an oven proof casserole dish and spread evenly.
Season the pork chops with salt and pepper. In the same pan, sear them for 1-2 minutes per side, adding more oil if nec. Sear the sides as well.
Place the seared chops in the casserole dish on top of the onions. Take some of the onions and spread over the top of the chops. Drizzle the mixture with chicken broth.
Bake covered in a preheated oven at 350℉ for 1½-2 hrs. Baste once or twice throughout the cooking process with juices and onions from the pan. Be sure the pan doesn't dry out while cooking, simply add more chicken broth if required.
Notes
This is a delicious way of preparing pork tenderloin as well. Simply clean any fat and silver skin from the tenderloin and slice into medallions.
