Instructions

  1. Preheat your oven to 450° F.
  2. In a small bowl, combine the butter, oil, garlic, rosemary, salt and pepper, and mix until a paste forms.
  3. Pat the pork roast with a paper towel to remove excess moisture and then rub 2/3 of the seasoning mixture onto the roast, covering the top and sides.
  4. Place the roast in the bottom of a large roaster.
  5. Place desired vegetables around the roast. Dab the remaining seasoning mixture over the vegetables.
  6. Roast uncovered in the pre-heated oven for 15 minutes, then turn the oven temperature down to 300° F.  Do not open the oven! 
  7. Let the roast continue to roast for another 20-25 minutes per pound of meat, around 100 minutes or until the internal temperature reaches 140° F when a meat thermometer is inserted into the middle.  
  8. Remove the roast from the oven and cover it with foil. Let it rest 10 minutes, then slice and serve.

Notes

  • New USDA recommendations are that pork can now be safely cooked to 145 °F.
  • The vegetables should be cut as small as you see in my photo, my roast cooked for 90 minutes as it was almost 6 pounds.
  • Carrots should be no wider than 1/2 inch, potatoes should be cut around 1/2 inch thick to ensure that they are cooked by the end of the roasting time. Smaller  sized vegetables will cook better.
