Things You'll Need:
- Oven
- Roasting pan
- Salt, pepper and seasonings
- Olive oil
- Meat baster
- Meat thermometer
- Carving knife
-
Step 1
Preheat your oven to 325 degrees F.
-
Step 2
Place your frozen pork roast in a roasting pan and rub the surface with 2 tsp. of olive oil. Season the outside of the roast with salt, pepper and any seasonings you desire. Thyme, oregano or garlic are good choices for pork roasts.
-
Step 3
Place the roast, uncovered, in the preheated oven.
-
Step 4
Determine the cooking time. Find the cooking time for your type of roast and add 50 percent for a frozen roast. A frozen crown or leg roast will require 30 minutes per pound and a frozen shoulder roast will need 45 minutes per pound.
-
Step 5
Baste the roast with the juices in the bottom of the pan at least two or three times while it cooks.
-
Step 6
Check your roast after the cooking time has ended. Pierce the middle of the pork roast with a meat thermometer, making sure the thermometer is not near a bone. Remove the roast from the oven when the thermometer reads 155 degrees F.
-
Step 7
Leave the roast in the pan until the meat thermometer reads 160 degrees F, which usually takes about 15 minutes.
-
Step 8
Slice the roast thinly and serve while warm. Mashed potatoes, roasted vegetables and dinner rolls are good accompaniments to pork roasts.
