Gradually add the milk, cook over medium heat, stirring constantly, until thickened and bubbly.
Stir in the salt, pepper, and onion powder. Taste to check the flavor and adjust the seasonings as you see fit.
Add the pork chops back into pan, including the juices to gravy; covering the chops with gravy.
Cover and simmer the pork chops about 45 minutes to 60 minutes (depending on thickness of meat). Occasionally, turn chops and stir the gravy to keep it from scorching. At this time, you can add more milk to thin out the gravy as you desire.
When done cooking, the meat should be very tender. At this time you can add browning sauce, if you desire. Stir it in and simmer another 5 minutes.
