Pork. It can be SO SO good, or it can be SO SO meh. To cook a pork loin that isn’t dry, bland, and tough, you really do need a good recipe. Don’t believe me? I’ve cooked a lot of bland pork roasts and dry pork chops already.
Things have changed here in the Real Housemoms kitchen though – pork is no longer bland and boring. Pork is my favorite meat to cook with. My husband loves it, my kids beg for it, and I love how simple it really can be!.
This pork loin roast recipe is great because it’s simple and everyone will love it, even picky eaters. The flavor palate is simple – garlic, onion powder, salt, pepper, and olive oil. You wouldn’t believe how well those few ingredients could work together to make a delicious meal that the whole family would love. All it takes is a sprinkle of seasoning and a few hours in the oven.
Perfectly Moist Pork Loin is a family favorite for all seasons. In the fall, pork and apples go well together, so I’ll cook a pork loin and serve it with my famous baked apples.
During the winter, it goes great with warm, creamy mashed potatoes (you need to try these Instant Pot Mashed Potatoes).
I also serve pork loin roast with chilled pasta salads when the weather gets warmer in the spring and summer. This Pesto Pasta Salad is perfect for that!
Pork roast is a classic main dish that seems simple but can go wrong if you don’t know how long to cook it properly. Undercooked pork not only lacks flavor but poses a health risk. Yet overcooking leads to dry, stringy meat. So what is the ideal roast time to ensure your pork is perfectly cooked from the outside in? This guide covers everything you need to know for moist, tender pork roast every time.
Factors That Affect Pork Roast Cooking Time
Several key factors impact the cooking time needed for pork roasts:
-
Size and thickness – A 5 lb roast takes longer than a 3 lb one Thickness is more important than weight,
-
Bone-in or boneless—Bone takes longer to heat up, so roasts with bones need more time.
-
Type of cut – Shoulder loin, sirloin all have varying densities.
-
Cooking method – Oven, slow cooker, grill or smoker all require different times.
-
Temperature – Higher heat cooks faster (but can dry out meat).
-
Browning – Getting a nice sear on the outside adds extra cooking time.
So there is no universal formula. But understanding how these variables affect timing helps estimate roast time.
Approximate Cooking Times for Different Pork Roast Cuts
These are general guidelines for how long common pork roast cuts take to cook at 325°F in the oven:
-
Pork shoulder roast – 18-24 minutes per lb
-
Pork loin roast – 15-20 minutes per lb
-
Pork sirloin roast – 18-22 minutes per lb
-
Pork tenderloin roast – 15-18 minutes per lb
-
Bone-in rib roast – 25-30 minutes per lb
-
Fresh ham roast – 20 minutes per lb
For example, a 3 lb boneless pork loin roast will need 45-60 minutes in a 325°F oven. Bone-in or fattier cuts take longer. Always rely on a meat thermometer for doneness, not just cook times.
Step-By-Step Guide to Cooking a Pork Roast
Follow these simple steps for roast pork success:
-
Select your roast – Pork shoulder, loin, sirloin all work well. Get 3/4 to 1 lb per person.
-
Prep the meat – Trim excess fat and tie roast with kitchen string for even cooking.
-
Season the roast – Rub seasoning or herbs and spices all over. Let sit 30 minutes.
-
Preheat oven to 325°F – Low, steady heat prevents overcooking.
-
Sear pork on stovetop (optional) – Brown for flavor and texture.
-
Place pork in roasting pan, fat-side up.
-
Roast in oven until internal temp reaches 145°F.
-
Remove roast and tent with foil. Let rest 10-15 minutes.
-
Carve roast into slices and serve!
The resting period allows juices to redistribute for a moist and tender meal.
How to Tell When Pork Roast is Cooked Properly
It can be tricky knowing exactly when a pork roast is properly cooked, but here are some tips:
-
Use an instant-read thermometer to check internal temp in thickest part. 145°F is ideal for slight pinkness. 160°F for well-done.
-
Check for visual doneness. Meat should be lightly browned outside. Inside should have just a hint of pink.
-
The roast may start to pull back from the bone if bone-in.
-
Test for tenderness. Well-cooked meat should be fork-tender and easy to shred.
Let roast rest at least 10 minutes before carving so juices have time to redistribute. If unsure, it’s always safer to cook a bit longer to 165°F for well-done pork.
Adjusting Cook Times and Temps for Perfect Results
To fine tune your roast cook times, keep these tips in mind:
-
For a crispier exterior, finish roast at 400°F last 10-15 minutes.
-
For a smoky flavor, roast low and slow at 225-250°F. It will need more time.
-
Thicker roasts need more time than wider shallow pieces.
-
Bone-in cuts take 10-15 minutes longer than boneless.
-
Brining adds moisture and flavor allowing slightly longer cook time.
-
Always rely on a meat thermometer for doneness, not just set time.
Master your oven, and you’ll turn out tender, juicy pork roast every time!
Oven Roasting Tips and Techniques
Follow these oven roasting tips for best results:
-
Let roast sit out for 30 minutes before cooking to warm up slightly before oven.
-
Preheat oven fully before putting roast in so oven stays at set temp.
-
Leave space around roast in pan and don’t tightly cover for air circulation.
-
Baste bone-in roasts during cooking to prevent the bone from drying out.
-
Add aromatic veggies like onions, garlic, carrots around the pork for flavor.
-
Use a meat thermometer to check for doneness in the thickest part.
-
For golden brown exterior, tent foil over pork then remove for last 20 minutes.
-
Allow roast to rest 10-15 minutes before slicing for juicier meat.
Proper oven roasting along with accurate temperature monitoring results in tender, juicy pork loaded with flavor.
How Long to Cook Pork Roast in a Slow Cooker
Cooking pork roast in a slow cooker or Crock Pot allows the meat to become ultra-tender and succulent. Here are general slow cooker pork roast guidelines:
-
Pork shoulder – 8-10 hours on LOW or 5-6 hours on HIGH.
-
Pork loin or sirloin – 6-8 hours on LOW or 4-5 hours on HIGH.
-
Boneless roast – Use times at lower end of ranges.
-
Add liquids like broth to moisten and prevent drying out.
-
Shred pork with forks when done for pulled pork sandwiches.
Due to the long, slow cooking, pork roast literally falls apart when perfectly cooked in the Crock Pot or Instant Pot.
Mastering the Perfect Pork Roast Grill Time
Grilling pork roast over charcoal, wood, or gas infuses tons of smoky flavor. These tips help you ace grill timing:
-
Choose a boneless roast for easiest grilling.
-
Get even heat on medium heat. Sear over direct heat.
-
Roast over indirect heat with a drip pan to catch juices.
-
Plan on 30-40 minutes total grilling time for a 3 lb roast.
-
Turn roast every 10-15 minutes for even cooking.
-
Brush with a glaze the last 10 minutes for a caramelized crust.
-
Let rest 10 minutes before slicing.
Use a digital instant-read thermometer to test for doneness out of the grill. Remove roast between 145-160°F for ideal juicy results.
Roasting Time Guidelines for Different Roast Sizes
To estimate pork roast cooking times, here are guidelines for 3 common roast sizes:
- 3 lb roast – 45-60 minutes
- 5 lb roast – 75-100 minutes
- 8 lb roast – 120-150 minutes
The roast shape also affects time. Short wide roasts may cook faster than long narrow ones of equal weight. Bone-in roasts need more time than boneless.
When cooking any size roast, always rely on an instant-read thermometer to check for proper internal temperature doneness rather than just total cooking time.
Adjusting Seasoning and Ingredients to Enhance Flavor
Don’t be afraid to experiment with flavors when roasting pork:
-Classic herb mixes like rosemary, thyme and sage bring warming flavors. Rub on roast before cooking.
-For Asian flavors, coat pork in hoisin, ginger and sesame oil before roasting.
-Apple, cranberries and maple syrup give pork a sweet tangy kick.
-Rub Mexican dry spices like cumin, chili powder and oregano on roast.
-Stuff herbs under the skin of boneless roasts for bursts of flavor.
-Coat roast with spicy mustard, brown sugar or fruit preserves last 30 minutes.
Infuse that pork roast with your favorite savory, spicy or fruity flavors.
Troubleshooting Pork Roast Problems
Having issues getting perfect results? Here are some common problems and solutions:
Undercooked roast – Return to oven and cook longer, testing every 10 minutes until desired internal temp.
Overcooked dry roast – For next attempt, use lower temp (300°F), pull at just 145°F and tent to rest.
Not flavorful – Double up on aromatics like garlic, onions, peppers, herbs. Marinate or rub spices into meat before roasting.
Burnt exterior – Use lower temp (300-325°F). Tent foil over roast next try to prevent burning.
Takes too long to cook – For quicker cooking, choose a boneless loin roast which cooks faster than bone-in or shoulder.
Getting the ideal roast time just takes practice. Keep notes so you learn how your oven works for the perfect juicy pork roast.
FAQs
What is the best cut of pork for roasting?
The pork loin and pork sirloin offer the most tender, juicy roasted meat. Fattier shoulder roast takes longer to cook but gives succulent pulled pork.
Should you cover pork roast while cooking?
It’s not necessary to cover a pork roast, but tenting foil over it for part of the cooking time helps retain moisture. Just remove foil last 20 minutes for browning.
How long does a 5 lb pork roast take to cook?
A 5 lb pork loin or sirloin roast generally takes around 90 minutes to cook in a 325°F oven. Thicker cuts take closer to 2 hours. Always rely on a meat thermometer for doneness.
Can you tell if pork is cooked by color?
Color can indicate doneness but is not fully reliable. Use a thermometer to check internal temp, as pork needs to reach 145°F minimum for food safety. At this stage it will have just a hint of pink inside.
What is the best way to cook a pork roast?
Seasoned pork roast cooked low and slow in the oven gives the most flavorful, tender meat. Use 325°F for oven roasting and monitor temperature. Or try a slow cooker on low for 8-10 hours depending on size.
Mastering the perfect pork roast timing is simple with the guides above. In no time, you’ll be serving juicy, delicious pork roast to rave reviews for any occasion!
How to Cook Pork Loin
- Start by preheating your oven to 400 degrees F. Even though the oven temperature will go down in the end, you start it off hot to really seal in the moisture on the outside of the pork loin!
- Next, sprinkle the pork with the spices (onion powder, garlic powder, salt, pepper, and olive oil). Do this on all sides. Make a small bowl of dry rub and put it on yourself. You can also use them one at a time. I like it better when it’s all mixed together before I put it on the meat. That way I know it’s being rubbed all over the roast evenly!
- Put the pork loin in the roasting pan with the fat side facing up. Putting the fat on top lets it baste the roast as it cooks. This step keeps the pork from getting tough and dry!
- Put the pork loin in an oven set to 400 degrees for 10 minutes. It will help make a “crust” on the meat that will keep the juices inside.
- Next, turn down the oven heat to 350 degrees F and cook the roast for another 20 minutes per pound of meat. Yes, it takes some time. But believe me, it’s worth the wait!.
- After the pork loin has reached 145 degrees F on the inside, take it out of the oven. After roasting the pork loin, set it aside for about 10 minutes with a piece of foil over it. Another very important step to keep the juices inside the meat where you want them to stay!! Patience is a virtue
When I make this pork loin roast recipe, my family comes running into the kitchen, almost begging for dinner to be ready. Someone or something about the long roasting time makes the whole house smell like delicious pork. My oldest son always says that the last 10 minutes of “rest” time for the meat seem like they last forever!

When I went to the grocery store to buy meat, I felt a little lost because I had never cooked with pork before because I couldn’t make it taste good! There are SO MANY different cuts of pork. You can choose from pork chops, pork loin, and pork tenderloin (yes, they are different, who knew?). It can be hard to decide which cut to get.
For this recipe, you’ll want to purchase a pork LOIN. Not chops, not tenderloin. The pork loin is different from other meat cuts because it is wide enough to cut into big pieces and has a lot of fat on top.
During cooking, this layer of fat is very important because it helps keep the meat’s juices inside. That’s what makes it so moist!.
