Preheat oven to 400 degrees.
Rinse and pat dry tenderloin. Generously coat with Tucker’s Competition Rub. Be sure to rub the spice mixture into the meat. It is called a rub after all.
Cook tenderloin for 30 to 40 minutes depending on the size. Internal temperature should be around 150. 145 to 150 degrees is the sweet spot for tenderloins.
Remove tenderloin from pan and allow to rest for 10-15 minutes.
The best way to make a pan sauce for this dish is by cooking the tenderloin in a large cast iron skillet, still in the oven, but in a skillet.
1.Thinly slice green onion whites and set aside.
Add butter to pan and start scraping the pan with a wooden spoon as the butter melts. This will help release crispy bits that attached themselves to pan during cooking.
Turn on the heat to medium. Add flour and cook for 1-2 minutes, stirring continuously.
Add green onion whites and continue to stir while cooking for another 1-2 minutes.
Add balsamic vinegar. Continue to stir while scraping the bottom of the pan.

Slice Tenderloin into medallions. Serve with pan sauce over the top. Garnish with green onion tops. We like to also serve ours with yellow rice and a roasted vegetables.
