Cooking a delicious pork loin roast in a slow cooker is a great way to prepare a mouth-watering meal with minimal effort. The slow cooker allows for even cooking and tenderization of the meat, resulting in a juicy and flavorful dish. However, one of the most common questions people have when cooking a pork loin roast in a slow cooker is how long to cook it. In this article, we will provide you with a comprehensive guide on how to cook the perfect pork loin roast in a slow cooker, including cooking times, temperatures, and tips for achieving the best results.
Understanding Pork Loin Roast
Before we dive into the cooking times and temperatures, it’s essential to understand the characteristics of a pork loin roast. A pork loin roast is a lean cut of meat, which means it has less fat compared to other cuts of pork. This makes it prone to drying out if overcooked. However, with the right cooking techniques and times, a pork loin roast can be incredibly tender and juicy.
Factors Affecting Cooking Time
Several factors can affect the cooking time of a pork loin roast in a slow cooker, including:
- Size and weight of the roast
- Temperature of the slow cooker
- Type of slow cooker used (e.g., digital, analog, or Instant Pot)
- Level of doneness desired (e.g., medium-rare, medium, or well-done)
Size and Weight of the Roast
The size and weight of the roast are significant factors in determining the cooking time. A larger roast will take longer to cook than a smaller one. Here’s a general guideline for cooking times based on the size and weight of the roast:
| Weight of Roast | Cooking Time (Low) | Cooking Time (High) |
| — | — | — |
| 1-2 pounds | 6-8 hours | 3-4 hours |
| 2-3 pounds | 8-10 hours | 4-5 hours |
| 3-4 pounds | 10-12 hours | 5-6 hours |
Cooking Temperatures and Times
The cooking temperature and time will depend on the level of doneness desired. Here are some general guidelines for cooking temperatures and times:
- Low and Slow: Cooking the pork loin roast on low for 8-10 hours will result in a tender and juicy dish. This method is ideal for a busy day when you can’t monitor the cooking process.
- High and Fast: Cooking the pork loin roast on high for 4-6 hours will result in a slightly less tender dish, but it’s still delicious. This method is ideal when you’re short on time.
Internal Temperature
Regardless of the cooking time and temperature, it’s essential to check the internal temperature of the roast to ensure it reaches a safe minimum internal temperature of 145°F (63°C). Use a meat thermometer to check the internal temperature, especially when cooking a larger roast.
Resting Time
Once the pork loin roast is cooked, it’s essential to let it rest for 10-15 minutes before slicing. This allows the juices to redistribute, making the meat even more tender and juicy.
Tips for Achieving the Best Results
Here are some tips to help you achieve the best results when cooking a pork loin roast in a slow cooker:
- Brown the Roast: Browning the roast before cooking it in the slow cooker will add flavor and texture to the dish. Use a skillet to brown the roast on all sides before placing it in the slow cooker.
- Use Aromatics: Adding aromatics like onions, carrots, and celery to the slow cooker will add flavor to the dish. You can also add herbs and spices to the roast for extra flavor.
- Don’t Overcook: Pork loin roast can become dry and tough if overcooked. Use a meat thermometer to check the internal temperature, and avoid overcooking the roast.

What are the benefits of cooking a pork loin roast in a slow cooker?
Cooking a pork loin roast in a slow cooker offers several benefits. One of the main advantages is that it allows for even cooking and tenderization of the meat. The low heat and moisture in the slow cooker break down the connective tissues in the meat, resulting in a tender and juicy roast. Additionally, cooking a pork loin roast in a slow cooker is a convenient and hands-off process, as it can be left to cook for several hours without requiring constant monitoring.
Another benefit of cooking a pork loin roast in a slow cooker is that it helps to retain the moisture and flavor of the meat. The slow cooker’s lid helps to trap the juices and aromas, ensuring that the roast is infused with flavor and remains moist and tender. This is especially important for leaner cuts of meat like pork loin, which can quickly become dry and overcooked if not cooked properly.
What is the ideal size of pork loin roast for a slow cooker?
The ideal size of pork loin roast for a slow cooker depends on the size of the slow cooker and the number of people being served. A general rule of thumb is to choose a roast that is between 2-4 pounds in size. This size roast will fit comfortably in most standard-sized slow cookers and will cook evenly in 8-10 hours. If you have a larger or smaller slow cooker, you may need to adjust the size of the roast accordingly.
It’s also important to consider the shape of the roast when choosing a size. A longer, thinner roast will cook more evenly than a shorter, thicker one. Look for a roast that is roughly the same thickness throughout, and trim any excess fat or connective tissue to ensure even cooking.
How do I season a pork loin roast for slow cooking?
Seasoning a pork loin roast for slow cooking is a matter of personal preference, but there are a few general guidelines to follow. First, make sure to season the roast liberally with salt and pepper, as these will help to bring out the natural flavors of the meat. You can also add other aromatics like garlic, onion, and herbs to the roast for added flavor.
One of the best ways to season a pork loin roast is to create a spice rub. Mix together your desired spices and herbs, such as paprika, thyme, and rosemary, and rub them all over the roast. You can also add a bit of brown sugar or honey to balance out the flavors. Let the roast sit for 30 minutes to an hour before cooking to allow the seasonings to penetrate the meat.
What is the best cooking liquid to use for a slow-cooked pork loin roast?
The best cooking liquid to use for a slow-cooked pork loin roast depends on the desired flavor profile. Some popular options include chicken or pork broth, apple cider vinegar, and beer. You can also use a combination of liquids to create a rich and complex flavor.
When choosing a cooking liquid, consider the flavor profile you want to achieve. If you want a classic, comforting flavor, chicken or pork broth may be the way to go. If you want something a bit more adventurous, try using apple cider vinegar or beer. You can also add aromatics like onion, carrot, and celery to the cooking liquid for added flavor.
How long does it take to cook a pork loin roast in a slow cooker?
The cooking time for a pork loin roast in a slow cooker will depend on the size of the roast and the desired level of doneness. As a general rule, a 2-4 pound roast will take 8-10 hours to cook on low or 4-6 hours to cook on high. It’s always best to use a meat thermometer to ensure the roast has reached a safe internal temperature of 145°F.
It’s also important to let the roast rest for 10-15 minutes before slicing and serving. This will allow the juices to redistribute and the meat to relax, resulting in a tender and juicy roast. You can also use the cooking time to prepare any additional sides or sauces to serve with the roast.
Can I cook a pork loin roast from frozen in a slow cooker?
Yes, it is possible to cook a pork loin roast from frozen in a slow cooker. However, it’s essential to follow some guidelines to ensure food safety. First, make sure the roast is in a leak-proof package or freezer bag to prevent cross-contamination. Then, place the frozen roast in the slow cooker and add your desired cooking liquid and seasonings.
Cooking a frozen pork loin roast in a slow cooker will take longer than cooking a thawed roast. As a general rule, add 2-3 hours to the cooking time for a frozen roast. It’s also crucial to use a meat thermometer to ensure the roast has reached a safe internal temperature of 145°F. Always err on the side of caution when cooking frozen meat to avoid foodborne illness.
How do I store and reheat a slow-cooked pork loin roast?
Once the pork loin roast is cooked, it’s essential to store it properly to maintain its quality and safety. Let the roast cool completely, then wrap it tightly in plastic wrap or aluminum foil and refrigerate or freeze.
