Delicious, juicy and tender pork tenderloin easily prepared in the oven. This pork tenderloin is rubbed with a flavorful mixture of Dijon mustard, brown sugar, and spices. All together, it will take only 30 minutes to prepare this wonderful main dish.
Preheat oven to 400°F and grease bottom of a roasting pan. It's best to use metal roasting pan because it's the best heat conductor.
Take out enough mustard from the jar and place it in a little bowl. (This will insure that you won't have to touch the main jar with dirty hands after touching raw pork.)
In a small bowl, combine brown sugar, garlic powder, onion powder, salt, and pepper. Mix well.
Take pork tenderloin out of the package and place it in the prepared roasting pan. Pat it dry and remove the silverskin if there is some left on the tenderloin.
Rub pork with Dijon mustard all over, even on the bottom and sides.
Sprinkle the seasoning all over the top of the pork and sides. Pat the seasoning down.
Place roasting pan in the oven and cook for 18-25 minutes. Time will depend on the size of the meat. Have a thermometer ready and start checking internal temperature after 18 minutes.
For juicy pork, it’s important not to overcook it. Cook pork until the internal temperature of the thickest side reads 145ºF.
Take it out and let it rest for about 5-10 minutes before cutting into it.
Expert tip: remember it's completely normal to see a slightly pink hue in the center of pork.
Notes
Silverskin: Silverskin is a white, shimmery connective tissue running along the outside of the tenderloin. To remove it, simply slide a sharp, thin knife under it and slide it across to separate from the meat. Try not to cut off any actual meat with it.
