This dish is perfect for busy weeknights, lazy Sundays, or meal prepping for the week. The crockpot does all the heavy lifting, slowly infusing your pork loin with spices, herbs, and moisture. And the best part? It’s one of the most forgiving recipes out there—even beginners in the kitchen can nail it on the first try.
So, whether you’re cooking for your family, prepping for the holidays, or just craving a home-cooked meal that hits all the right notes, this step-by-step guide has you covered.
What is Pork Loin?
Before diving into the recipe, let’s clear up what pork loin really is—because it often gets confused with pork tenderloin. Pork loin is a larger, wider cut of meat that comes from the back of the pig. It’s lean, yet flavorful, with just enough fat to stay juicy when cooked properly.
Unlike the tenderloin, which is long and narrow and cooks quickly, pork loin is thick and suited to slower cooking methods—like roasting or, of course, slow cooking in a crockpot. That makes it ideal for soaking up all the seasonings and liquids you’re going to throw in.
You can buy pork loin bone-in or boneless, and both work well for slow cooking. The boneless version is easier to slice and serve, but the bone-in one can offer slightly more flavor. Either way, it’s a cut that gives you maximum flavor with minimal effort.
Why Cook Pork Loin in a Crockpot?
Here’s the thing: pork loin can dry out pretty quickly if you cook it too fast or too hot. That’s where the magic of the crockpot comes in. Cooking it low and slow gives the meat time to break down gently, resulting in a tender, juicy roast that falls apart with a fork.
Using a crockpot also means you don’t have to babysit your stove or oven. You can go about your day, run errands, work from home, or binge-watch your favorite series while dinner basically cooks itself.
Beyond convenience, the crockpot helps the pork soak up all the spices, aromatics, and liquids you toss in. The result? Every bite is infused with flavor, not just the surface. It’s like marinating and roasting in one process.
Still wondering if you need a crockpot in your life? Try this pork loin recipe once, and you’ll have your answer.
List of Ingredients You’ll Need
To make the perfect crockpot pork loin, here’s your go-to shopping list:
Main Ingredients:
- 1 (3–4 lb) pork loin (boneless or bone-in)
- 2 tablespoons olive oil (for searing)
- 1 tablespoon salt
- 1 teaspoon black pepper
- 1 tablespoon garlic powder
- 1 tablespoon onion powder
- 1 tablespoon smoked paprika
- 1 teaspoon dried thyme
- 1 teaspoon rosemary (dried or fresh)
- 2–3 garlic cloves, minced
- 1 onion, sliced
- 1 cup chicken broth or beef broth
- 2 tablespoons soy sauce or Worcestershire sauce
- 2 tablespoons brown sugar (optional, for a hint of sweetness)
Optional Add-Ons:
- 2 apples, sliced (for a hint of sweetness)
- 3–4 carrots, peeled and chopped
- 2–3 potatoes, quartered
- A splash of apple cider or balsamic vinegar
- BBQ sauce or honey mustard for serving
Substitutions:
- No olive oil? Use avocado oil or butter.
- Out of thyme? Italian seasoning works great.
- No broth? Use water plus a bouillon cube.
Keep in mind, this recipe is flexible. You can adjust spices based on your preferences. Don’t have brown sugar? Skip it. Want it spicy? Add some chili flakes or cayenne.
Choosing the Right Pork Loin
Not all pork loins are created equal, and picking the right cut can make a big difference in how your final dish turns out. When you’re at the butcher or grocery store, look for a pork loin that’s about 3 to 4 pounds for a standard crockpot meal. This size is perfect for feeding 4 to 6 people, and you’ll likely have leftovers too (which is always a win!).
Bone-In vs. Boneless:
- Boneless Pork Loin is easier to handle, slice, and cook evenly. It’s a popular choice for crockpot recipes because you don’t have to work around the bone.
- Bone-In Pork Loin tends to have more flavor thanks to the bone marrow and connective tissue. However, it may take a bit longer to cook and can be a little messier when slicing.
Fat Cap – Trim or Leave It?
You might notice a thick layer of fat on one side of the loin. That’s called the fat cap. Some cooks prefer to trim it down a bit, leaving only about ¼ inch. Others leave it on to baste the meat during cooking. Either option is fine; it just depends on how rich you want your meat.
Color and Texture:
Look for a loin that is pale pink with a fine grain. Avoid any cuts that are overly dark or have a grayish hue—they’re past their prime. Also, it should feel firm to the touch and have a slight marbling of fat throughout for added juiciness.
Choosing the right cut sets the stage for everything else. Take the time to inspect your meat, and you’ll taste the difference in every bite.
Equipment You’ll Need
One of the best things about crockpot recipes is that you don’t need fancy gadgets—just a few kitchen basics and you’re all set. But having the right tools on hand can make the cooking process smoother and the final result more delicious.
Must-Have Tools:
- Crockpot / Slow Cooker: Opt for a 6-quart model if you’re cooking a 3–4 lb pork loin. Make sure it has a “Low” and “High” setting, and ideally a “Keep Warm” mode.
- Tongs: To flip or transfer the pork without piercing it too much, which can let juices escape.
- Meat Thermometer: This is non-negotiable if you want to ensure perfect doneness. A digital, instant-read thermometer is best.
- Cutting Board + Sharp Knife: For slicing after it rests. A good, sharp chef’s knife will glide through the meat like butter.
- Searing Pan (optional): If you choose to sear your pork loin before slow cooking, a cast iron skillet or heavy-bottomed pan works great.
- Gravy Separator (optional): If you’re planning to make gravy from the juices, this tool helps separate the fat from the liquid gold.
With this simple lineup, you’ll be more than ready to conquer this pork loin recipe like a pro.
How to Season Pork Loin for Crockpot
Seasoning is everything when it comes to pork loin. This lean cut benefits massively from a flavorful rub or marinade. Think of it like giving the meat a personality before it even starts cooking.
Dry Rubs:
A dry rub is the go-to method for seasoning a pork loin going into the crockpot. Here’s a quick rub that hits all the right notes:
- 1 tbsp salt
- 1 tsp black pepper
- 1 tbsp garlic powder
- 1 tbsp smoked paprika
- 1 tsp thyme
- 1 tsp rosemary
- 1 tsp onion powder
Mix all of these in a small bowl and rub generously all over the pork loin—don’t be shy, really massage it in.
Optional Additions:
- Brown Sugar – Adds a subtle sweetness and helps create a crust if you sear first.
- Cayenne or Chili Powder – If you want a little kick.
- Mustard or Honey – Brush over the loin before adding spices for extra depth.
Marinades:
If you’ve got the time, marinate the pork loin overnight in a mix of olive oil, vinegar, garlic, and herbs. While not necessary, it deepens the flavor even more.
Whichever route you go—rub or marinade—just remember: seasoning is not optional. It’s what turns a plain piece of pork into a dinner worth remembering.
Step-by-Step Guide to Making Crockpot Pork Loin
Now for the moment you’ve been waiting for—let’s cook!
Step 1: Prep the Pork
Pat the pork loin dry with paper towels. This helps the seasoning stick better. Trim off any excess fat if desired, but leave a little for flavor. Apply your dry rub evenly across the entire surface.
Step 2: (Optional) Sear for Flavor
Heat a pan over medium-high heat and add a little olive oil. Sear the pork loin for 2–3 minutes per side, until browned. This step adds a caramelized crust that’s loaded with flavor, but you can skip it if you’re in a rush.
Step 3: Add Ingredients to the Crockpot
Layer the bottom of your crockpot with sliced onions and garlic. Place the pork loin on top. Pour in your broth, soy sauce, and any optional ingredients like carrots, apples, or potatoes.
Suggested Layering Order:
- Onions & garlic (base layer)
- Pork loin (centerpiece)
- Carrots/apples/potatoes (around the edges)
- Liquid over everything
Step 4: Choose Your Cooking Setting
- Low: Cook for 6–8 hours
- High: Cook for 3.5–4.5 hours
Remember, low and slow usually gives the most tender results.
Step 5: Rest and Slice
Once the pork reaches an internal temp of 145°F (63°C), remove it and let it rest for 10–15 minutes before slicing. This helps the juices redistribute so they don’t all spill out when you cut it.
The end result? Juicy, fork-tender pork that practically melts in your mouth.
What Liquids to Use in the Crockpot
The choice of liquid you use in your crockpot makes a huge difference. It not only keeps the pork loin moist during the slow cook but also becomes the base for a flavorful sauce or gravy. Think of the liquid as a flavor bath—your pork is soaking up all those delicious tastes for hours.
Best Liquid Options:
- Chicken or Beef Broth: These are the most common choices and offer a savory, rich base. Opt for low-sodium broth so you can control the salt level.
- Apple Juice or Apple Cider: Great for adding a sweet, slightly tangy flavor that pairs perfectly with pork.
- White Wine or Red Wine: Adds depth and complexity to the dish. Use a dry wine that you’d actually drink.
- Balsamic Vinegar + Honey: This combo creates a slightly sweet and tangy glaze that’s irresistible.
- BBQ Sauce or Mustard-Based Sauces: For a Southern twist, pour a cup of your favorite BBQ sauce right over the pork. Adds flavor and a ready-to-go sauce.
How Much Liquid Do You Need?
Less than you might think. Pork loin naturally releases juices while cooking, so you only need:
- 1 to 1.5 cups of liquid total (broth, juice, or sauce combo).
Too much liquid can cause the meat to boil instead of slow-cook and braise, which may leave it soggy or rubbery. Keep it minimal, just enough to create steam and moisture.
Remember, this liquid isn’t just for cooking—it’s for flavor. Choose wisely, and you’ll be amazed at how rich and delicious your pork turns out.
How Long to Cook Pork Loin in a Crockpot
This is one of the most frequently asked questions—and for good reason. Pork loin is lean, so overcooking it will turn that juicy roast into a dry, chewy disappointment.
Here’s a breakdown to get it just right:
General Cook Times:
- Low Setting: 6–8 hours
- High Setting: 3.5–4.5 hours
Per Pound Rule of Thumb:
- About 1.5 to 2 hours per pound on LOW
- About 40 to 60 minutes per pound on HIGH
Key Cooking Tips:
- Don’t lift the lid! Every time you open it, heat escapes and cooking slows down.
- Use a meat thermometer to check doneness.
- Aim for an internal temperature of 145°F (63°C) for juicy, safe-to-eat pork.
- After reaching the desired temp, let it rest for 10–15 minutes before slicing.
If you cook it too long, even on low, it can still dry out. So set a timer, use your thermometer, and don’t just “set it and forget it” until you’re familiar with your slow cooker’s quirks.
Temperature and Doneness Guide
Nothing ruins a pork loin faster than guessing whether it’s done. Here’s how to ensure it’s perfectly cooked—not underdone, not dried out—just right.
Safe Pork Internal Temperatures:
- Medium (Juicy & Slightly Pink): 145°F (63°C)
- Medium-Well (Less Pink): 150–155°F (65–68°C)
- Well Done (Fully Cooked, No Pink): 160°F+ (71°C+)
According to USDA guidelines, pork is safe to eat at 145°F, followed by a 3-minute rest. Don’t panic if it’s a little pink inside—that’s normal and totally safe when it hits the right temp.
Best Practices for Measuring Temp:
- Use a digital instant-read thermometer.
- Insert it into the thickest part of the pork loin, avoiding any bones or fat.
- Take the temperature at the end of cooking, just before you remove it.
Why Resting Matters:
When you pull the pork loin from the crockpot, the internal juices are still circulating. If you slice it too soon, they’ll run out and leave the meat dry. Letting it rest allows those juices to redistribute—so every bite is juicy and tender.
Temperature and timing are the make-or-break factors. Nail them, and you’ll have a pork loin that’s worthy of seconds (and thirds).
How to Make a Gravy or Sauce from the Juices
You’ve done the hard part—now let’s elevate your pork loin even further. The juices left in your crockpot are liquid gold, packed with flavor and just begging to be turned into a silky gravy or rich sauce.
Simple Gravy Recipe:
- Strain the Juices: Remove any solid bits like onions or garlic. You can leave them in if you like a chunkier texture.
- Skim the Fat (optional): Use a spoon or fat separator if the juices are too greasy.
- Make a Slurry:
Mix 2 tablespoons cornstarch (or flour) with ¼ cup cold water. - Simmer and Whisk:
Pour the juices into a saucepan over medium heat. Add the slurry slowly while whisking. - Add Flavor Boosters (optional):
A splash of balsamic vinegar, a teaspoon of mustard, or a bit of cream can level things up.
Simmer until thickened to your liking. Season with salt and pepper to taste. Boom—restaurant-quality gravy in under 10 minutes.
Not into gravy? Just serve the pork sliced with the au jus (natural juices) straight from the crockpot for a more rustic presentation.

- In the Refrigerator: Let the pork loin cool completely, then transfer it to an airtight container. Store it in the fridge for up to 4 days.
- In the Freezer: Slice or shred the pork and freeze in portions with a bit of the cooking liquid to keep it moist. Use freezer-safe bags or containers, and label with the date. It’ll stay good for up to 3 months.
Reheating Tips:
- Microwave: Place slices in a microwave-safe dish with a splash of broth or water. Cover and heat in 30-second intervals until warmed through.
- Oven: Wrap in foil with some juices and warm at 300°F (150°C) for about 15–20 minutes.

Leftovers don’t have to be boring. A little imagination, and you’ve got several more meals out of one slow-cooked roast.
Common Mistakes to Avoid
Even though crockpot pork loin is fairly foolproof, there are a few mistakes that can mess things up. Avoiding these will help you nail the recipe every time.
1. Overcooking the Pork
Yes, you can overcook pork even in a crockpot. If it’s dry or stringy, it probably cooked too long or at too high a temperature. Always use a meat thermometer and check for 145°F internal temp.
2. Using Too Much Liquid
Your pork loin doesn’t need to swim. Slow cookers don’t evaporate liquid like ovens, so a little goes a long way. Too much, and you end up boiling the meat, which affects texture and flavor.
3. Not Searing First (Optional but Important)
Searing isn’t mandatory, but it adds a caramelized crust and extra depth. If you have time, do it—you won’t regret it.
4. Skipping the Rest Time
Cutting into the pork right after cooking causes all the juices to run out. Let it rest for 10–15 minutes to keep it juicy.
5. Using Pork Tenderloin Instead of Loin
They are not the same cut! Tenderloin is smaller, thinner, and cooks much faster. If you use it in place of pork loin, it’ll likely overcook.
Avoid these common pitfalls and you’re pretty much guaranteed a pork loin that’s flavorful, juicy, and downright crave-worthy.

FAQs about Crockpot Pork Loin Recipe
1. Can I cook a frozen pork loin in the crockpot?
Technically yes, but it’s not recommended. Slow cookers take a long time to reach safe temperatures, so starting with frozen meat could keep it in the “danger zone” too long. Always thaw your pork loin in the fridge overnight first.
2. What’s the difference between pork loin and pork roast?
“Pork roast” is a general term for larger cuts of pork used for roasting—this includes pork loin and shoulder. Pork loin is lean and tender, while pork shoulder is fattier and better suited for pulled pork.
3. How can I make this recipe keto-friendly?
Easy—skip the brown sugar and use low-carb sides like cauliflower mash or roasted veggies. Double-check that your broth and sauces have no added sugars.
4. Can I use BBQ sauce instead of broth?
Absolutely. A cup of BBQ sauce can be used as your main liquid. Just know it’ll create a much sweeter, tangier dish—great for sandwiches or a Southern-style dinner.
5. Should I flip the pork loin while it cooks?
No need. The crockpot’s slow, even heat cooks the pork from all sides. Flipping can actually disrupt the cooking process and cause moisture loss when you lift the lid.
