Pork roast is a classic main dish that’s delicious, satisfying, and surprisingly easy to make. But to achieve tender, juicy results, it’s crucial to know how long to roast your pork properly.
Cooking times can vary based on the size, cut, and preparation method. This guide covers everything you need to know about cooking pork roast so it turns out mouthwateringly perfect every time.
Overview of Pork Roasts
Let’s start with an overview of the most common pork roasts
-
Pork loin roast – This lean, tender cut comes from the loin primal. It has little fat and dries out easily if overcooked
-
Pork shoulder roast – Also called a Boston butt or pork butt roast. It comes from the upper shoulder and contains more fat and collagen for added moisture and flavor.
-
Pork tenderloin roast – A small cylindrical roast with very lean meat. Cooks quickly and needs extra care not to overcook.
-
Fresh ham roast – From the rear leg, it’s leaner than a smoked ham roast. Has great flavor when properly cooked.
-
Cured or smoked ham roast – Offered bone-in or boneless. Wet curing and smoking add flavor, saltiness, and tenderness.
The cut you select affects the recommended roasting time, so let’s look at how long each takes.
How Long to Cook Pork Loin Roast
A boneless pork loin roast typically requires:
-
Oven temperature: 325°F
-
Cooking time: About 20 minutes per pound
-
Minimum internal temperature: 145°F before resting
As a leaner cut, pork loin can dry out if cooked too long. Use a meat thermometer to check for doneness instead of relying solely on roasting times.
How Long to Cook Pork Shoulder Roast
Pork shoulder or Boston butt roasts contain more fat and collagen. For optimal tenderness, cook low and slow:
-
Oven temperature: 250°F to 300°F
-
Cooking time: Estimate 30 minutes per pound
-
Internal temperature: 190°F-205°F for shredding
The collagen breaks down at higher temperatures to yield incredibly tender meat. Cook times vary greatly for shoulder roasts based on size and temperature.
How Long to Cook Pork Tenderloin Roast
The small, lean tenderloin roast requires less time:
-
Oven temperature: 425°F
-
Cooking time: About 20 minutes per pound
-
Minimum internal temperature: 145°F
Roast at a higher temperature since this cut cooks faster. Rely on a meat thermometer for accuracy.
How Long to Cook Fresh Ham Roast
For an uncooked fresh ham roast:
-
Oven temperature: 325°F
-
Cooking time: 20-25 minutes per pound
-
Minimum internal temperature: 145°F before resting
Fresh ham comes from the leg so it contains a bit more fat and collagen than loin. Monitor temperature to prevent drying out.
How Long to Cook Smoked Ham Roast
Fully cooked smoked ham roasts simply need reheating:
-
Oven temperature: 325°F
-
Cooking time: 10-15 minutes per pound
-
Internal temperature: 140°F
A cured smoked ham is safe when reheated to 140°F. Never eat cold or raw ham.
Roasting Tips for Perfect Results
Follow these tips regardless of the pork roast cut you choose:
-
Bring roasts to room temperature before cooking.
-
Tie roasts with butcher’s twine to maintain shape.
-
Sear all sides in a hot pan before roasting for caramelized flavor.
-
Use a meat thermometer to check internal temperature.
-
Let rest 10-15 minutes before slicing to allow juices to redistribute.
Proper roasting along with monitoring temperature delivers incredibly juicy, tender pork roast.
Common Roasting Problems and Solutions
Having trouble getting your pork roast just right? Here are some common roasting issues and how to fix them:
Dry, tough meat – This happens when pork is overcooked. Use a thermometer and don’t exceed the recommended internal temperature.
Takes too long to cook – Very large roasts over 5 pounds will require additional roasting time. Calculate 30-35 minutes per pound for extra large cuts.
Burned outside, undercooked inside – Reduce the oven temperature and roast for longer to cook through without burning.
Uneven cooking – Position roasts away from heat sources, rotate pans, and cover ends with foil if cooking unevenly.
Lacks flavor – Enhance taste by brining before roasting. Apply rubs, marinades, or glazes to add lots of flavor.
With the proper roasting guidelines and techniques, you can achieve perfect results every time. Never guess—use a meat thermometer!
Frequently Asked Questions
What if my pork roast is thicker on one end?
Cover the thicker end with foil to prevent overcooking. Remove it halfway through roasting to brown and crisp up.
Can I slow roast a pork loin or tenderloin roast?
You can slow roast smaller lean roasts, but extend cooking times. Cook at 225-250°F and use a thermometer to avoid drying out the meat.
Is it better to roast bone-in or boneless pork roasts?
Bone-in roasts take slightly longer to cook but add extra flavor. Boneless cuts roast more evenly. Choose based on your recipe and preferences.
Should I flip a pork roast while roasting?
Flipping is not necessary. Placing fattier side up allows the fat to baste the meat. Rotate the pan halfway through if desired.
Can I roast a fresh ham roast cooked like a smoked ham?
Fresh ham requires cooking to 145°F since it’s raw. Smoked ham simply needs reheating to 140°F since it’s fully cooked. Don’t roast fresh ham like a smoked ham.
