Step 1

Preheat to 400°F.

Step 2

Mix first 5 ingredients in bowl. Then rub the garlic mixture all over pork.

Step 3

Add olive oil to a small casserole pan, place in the sliced onions and apples, toss them in the oil to lightly coat and spread out creating a "rack".

Step 4

Pour in one cup of the white wine, add the butter and place the pork on top of the onions and apples.

Step 5

Take a piece of parchment paper large enough to cover the pork, and scrunch it up then run it under cold water. Open it back up, and create a tent over the pork, tucking it carefully over the meat, onions and apples.

Step 6

Cook for 20 minutes, carefully uncover and add remaining wine, cover again and continue to cook for 30 - 40 minutes. Allow meat to rest for 10 - 15 minutes before slicing.

Step 7

Pour any juices from roasting pan into small saucepan; set over low heat to keep warm. Cut pork crosswise into desired thickness. Arrange pork slices as desired, top with the onions and apples, then pour pan juices over top. Garnish with rosemary sprigs, if desired.
