How to Cook Pork Tenderloin in a Roaster

Pork tenderloin comes from the inside of a hog loin, which is the tissue along the top of the rib cage. It is one of the tenderest cuts of pork. The tenderloin's mild flavor lends itself to a variety of seasoning options, whether the seasoning comes in the form of a spice rub, marinate or flavorful sauce. Roasting is an easy and fairly quick way to prepare pork tenderloin, which usually weighs between 3/4 lb. and 1-1/2 lbs. Another advantage of roasting is that it allows fat to drip away from the meat while it cooks.

Step 1

Trim any fat from the pork tenderloin. Mix together 1/2 tsp. each dried oregano, thyme, coriander, cumin and curry powder in a small bowl. Add 1/4 tsp. salt to the spice mixture.

Step 2

Moisten the tenderloin and rub in the spices. Place the tenderloin in a shallow dish and refrigerate for up to eight hours.

Step 3

Heat oven to 450 degrees Fahrenheit. Place the pork on a rack inside the roaster. Roast the tenderloin for about 20 minutes or until it reaches an internal temperature of 155 degrees.

Step 4

Take the pork from the oven and loosely cover it with aluminum foil. Allow it to rest for five minutes so juices can set.

Step 5

Slice the pork tenderloin, garnish with parsley and serve. Makes about four servings.
