Here are several pan sauces, quick to make and easily adjusted to individual tastes. Normally one makes a pan sauce after searing or cooking the meat in the pan. We will use the accumulated juices in the foil your pork tenderloin comes in. Simply rinse the foil with either wine or chicken broth that is going into the pan sauce anyway.
*You can easily double or triple these recipes. They are for one Pork Tenderloin.
Red Wine Pan Sauce
1 lg Shallot, minced
¾ cup Red Wine
¾ cup Chicken Broth
1 T Brown Sugar, packed
2 T Butter, separated
1 t fresh Rosemary, minced
½ t Balsamic Vinegar
½ t Freshly Ground Pepper

Marsala and Porcini Pan Sauce

¼ oz dried Porcini Mushrooms (other varieties are fine)
Can substitute fresh mushrooms, about 2-3 ounces, diced
¾ cup Marsala
¾ cup Chicken Broth
2 T Butter
1 T Parsley
Salt and Pepper to taste
Microwave ½ cup broth with the dried mushrooms until hot then let sit covered until soft (~5 min). Drain, reserving liquid, then chop
Heat your pan, add oil then shallots, cook until soft *if using fresh mushrooms saute mushrooms first until they lose their liquid then add the shallots
Add Marsala and simmer until reduced by half
Add remaining chicken broth and mushroom soaking liquid, simmer until reduced by half

**If you like sauces a bit thicker either reduce the wine more or after chicken broth is reduced combine 1 t corn starch with 1 T water and whisk it into the sauce.
