4 Ingredient Balsamic Roasted Pork Loin

This sort of breaks the 4 Ingredient rule as you have to make the Spice Rub first.  But that only has four ingredients too so we thought the cheat was justified.

INGREDIENTS:
STEAK SEASONING RUB

• ¼ cup ground black pepper
• ¼ cup garlic powder
• ¼ cup onion powder
• 2 tablespoons sea salt

PORK LOIN

• 2 tablespoons steak seasoning rub
• ½ cup balsamic vinegar
• ½ cup olive oil
• 2 pounds/1 kilogram boneless pork loin roast

DIRECTIONS:
​STEAK SEASONING RUB

1. Measure spices out and place into a small bowl
2. Stir together to mix well
3. Use as a steak rub or mix into ground beef
4. Store in a glass jar with a well-sealed screw lid

​
PORK LOIN

1. Dissolve steak seasoning in balsamic vinegar, then stir in olive oil.
2. Place pork into a resealable plastic bag and pour marinade over top.
3. Squeeze out air and seal bag; marinate 2 hours to overnight.
4. Preheat oven to 350°F/180°C.
5. Place pork into a glass baking dish along with marinade.
6. Bake in preheated oven, basting occasionally until the pork reaches an internal temperature of 145 degrees Fahrenheit/65 C, about 1 hour.

Let the roast rest for 10 minutes before slicing and serving.
