One important thing to remember: pork tenderloin and pork loin are not the same cut.
Pork tenderloin is a long, narrow, very lean cut that cooks relatively quickly. Pork loin is larger and thicker and needs different cooking times.
For this recipe, use pork tenderloin.
If your package contains two smaller tenderloins, that's perfectly fine. You can cook them together as long as they fit comfortably in your slow cooker.
Ingredient Additions and Substitutions
This recipe is wonderfully flexible.
Use Different Herbs
Try Italian seasoning instead of the individual thyme and rosemary.
Fresh rosemary and thyme can also be used. Just remember that fresh herbs are generally more potent than dried.
Add Vegetables
You can add:
- Carrots
- Baby potatoes
- Mushrooms
- Celery
- Green beans
- Bell peppers
Keep in mind that adding lots of vegetables can change the amount of liquid and cooking time.
Swap the Sweetener
Honey can be replaced with:
- Brown sugar
- Maple syrup
- Apple jelly
- Apricot preserves
The sweetness helps balance the savory sauce.
Make It Creamy
For a creamy version, stir a little heavy cream or sour cream into the finished sauce after the pork is cooked.
Don't add sour cream at the beginning of a long slow-cooking process, as it can separate.
Add Apple
For a fall-inspired version, add sliced apples during the final portion of cooking. Pork and apples are such a classic combination for a reason!
How to Make Slow Cooker Pork Tenderloin
Step 1: Prepare the Pork
Pat the pork tenderloin dry with paper towels.
This helps the seasonings stick and gives you a better surface for browning if you choose to sear the pork first.
Trim away any excess silver skin if necessary.
Step 2: Season Generously
Combine the salt, pepper, garlic powder, onion powder, thyme, rosemary, and paprika.
Rub the seasoning mixture all over the pork.
Don't be shy with the seasoning. Pork tenderloin is lean and mild, so this is where we build that wonderful flavor.
Step 3: Brown the Pork
This step is optional, but I highly recommend it!
Heat the olive oil in a skillet over medium-high heat. Brown the pork for about 2 minutes per side, just until the outside develops a golden-brown crust.
You aren't trying to cook it through.
You're simply building another layer of flavor.
Step 4: Prepare the Slow Cooker
Place the sliced onion and minced garlic in the bottom of the slow cooker.
Set the seasoned pork tenderloin on top.
Step 5: Make the Sauce
In a small bowl, whisk together:
- Chicken broth
- Worcestershire sauce
- Dijon mustard
- Honey
- Tomato paste
- Thyme
- Black pepper
Pour the mixture around the pork.
Step 6: Slow Cook
Cover and cook on LOW for about 3–4 hours, depending on the size of your tenderloin and your slow cooker.
You can also cook it on HIGH for approximately 1½–2½ hours, but the low setting is preferable when you have the time.
Because pork tenderloin is lean, don't simply cook it all day like a pork shoulder. Overcooking can make this particular cut dry.
Step 7: Check the Temperature
Use an instant-read thermometer to check the thickest part of the tenderloin.
Cook pork to a safe internal temperature of 145°F (63°C), followed by a short rest.
Step 8: Let the Pork Rest
Transfer the pork to a cutting board and let it rest for about 5–10 minutes before slicing.
This gives the juices time to redistribute.
I know it's tempting to slice immediately, especially when the kitchen smells amazing, but give it those few minutes!
Step 9: Make the Gravy
If you'd like a thicker sauce, pour the cooking liquid into a saucepan.
Whisk together the cornstarch and cold water to make a slurry.
Bring the cooking liquid to a gentle simmer and slowly whisk in the slurry. Cook for a few minutes until thickened.
Taste and adjust the seasoning if necessary.
Step 10: Slice and Serve
Slice the pork into medallions and arrange them on a serving platter.
Spoon the warm gravy over the top and sprinkle with fresh parsley.
Look at that!
Simple ingredients, beautiful presentation, and a dinner that looks like you worked much harder than you actually did. 😊

Tips for the Best Slow Cooker Pork Tenderloin
Don't Confuse Tenderloin With Pork Loin
This is probably the biggest thing to watch for. They are different cuts and aren't interchangeable without adjusting the recipe.
Don't Overcook It
Pork tenderloin is lean.
That's wonderful for a lighter dinner, but it also means it can become dry if cooked far beyond its ideal temperature.
Start checking early.
Pat the Pork Dry
A dry surface helps seasoning adhere and encourages better browning.
Searing Is Optional
If you're short on time, you can skip browning and put the seasoned pork directly into the slow cooker.
But if you have an extra few minutes, searing adds delicious flavor.
Don't Keep Opening the Lid
Every time you lift the slow cooker lid, heat escapes.
Keep that lid closed as much as possible.
Let It Rest
Those 5–10 minutes can make a noticeable difference in how juicy the pork feels when sliced.
Slice Against the Grain
Look at the direction of the muscle fibers and slice across them rather than parallel to them.
This makes each bite easier to chew.
Can You Make This Recipe Ahead?
Absolutely!
You can prepare the pork and sauce several hours ahead and keep everything refrigerated until you're ready to cook.
You can also cook the pork earlier in the day and gently reheat it before serving.
For the best texture, avoid repeatedly reheating the pork.
How to Store Leftovers
Place leftover pork in an airtight container and refrigerate within two hours.
It will generally keep for about 3–4 days in the refrigerator.
Store some of the sauce with the pork to help keep it moist when reheating.
How to Reheat
Reheat gently in the microwave in short intervals or in a covered skillet over low heat.
A splash of broth can help loosen the sauce.
Can You Freeze Pork Tenderloin?
Yes.
Cool the pork completely, slice it if desired, and place it in a freezer-safe container or bag with some of the sauce.
Freeze for up to about 2–3 months for best quality.
Thaw overnight in the refrigerator and reheat gently.

Frequently Asked Questions
Can I put raw pork tenderloin directly into the slow cooker?
Yes. You can season the pork and place it directly into the slow cooker.
Browning is optional and is primarily done for additional flavor and color.
Why is my pork tenderloin dry?
The most common reason is overcooking.
Pork tenderloin is very lean, so it doesn't benefit from extremely long cooking times in the same way that tougher cuts such as pork shoulder do.
Use a thermometer rather than relying only on the clock.
Can I use pork loin instead?
You can, but pork loin is a different cut and will require different cooking instructions.
For the recipe as written, stick with pork tenderloin.
Should I add the gravy at the beginning?
No.
The cornstarch slurry is best added after cooking so you can control the thickness of the sauce.
Can I cook vegetables with the pork?
Yes. Carrots, potatoes, onions, and mushrooms can all work beautifully.
Cut vegetables into appropriately sized pieces so they cook evenly.
Can I make this without Dijon mustard?
Absolutely.
You can leave it out or substitute a little yellow mustard. The flavor will be slightly different, but the recipe will still work.
Can I make this recipe gluten-free?
The ingredients themselves can be adapted for a gluten-free diet, but check the labels of your Worcestershire sauce, mustard, broth, and other packaged ingredients to make sure they meet your needs.
