Heat olive oil in a Dutch oven or oven safe skillet on medium high heat on the stove-top. Preheat oven to 425 degrees.
Combine all spice. Add spices and pork loins to a seal-able bag and shake to coat. Use tongs to move coated pork loins to the hot pan to sear. Sear the pork loin on all 4 sides, approximately 2 minutes per side.
Once the pork loin is seared, move the oven safe pan to the oven to bake for 10-12 minutes. Or until the pork reaches 145 degrees. Remove the pork loin from the oven and let it rest for 10 minutes. Serve hot and enjoy!
