Why this slow cooker pork loin recipe works
This Slow Cooker Pork Loin with Mushroom Sauce solves the common pitfalls of slow-cooked pork. It turns out tender, never dry, with a gravy that tastes like you spent all day on it. Three things make the difference.
Transforming an inexpensive cut
A pork loin is a large, lean roast that’s budget-friendly but can easily become tough. This recipe treats it right. You sear it first to build a flavorful crust, then let the slow cooker do a gentle, moist braise. Cooking it for 6 hours on Low brings it to the perfect internal temperature for shredding tenderness without overcooking. It’s different from a quick-cooking pork tenderloin (see the FAQ for details).
The luxurious mushroom gravy
The sauce is where the magic happens. Sliced mushrooms and onions cook down into a savory base. Adding sherry (not cooking wine) gives the gravy a depth of flavor that plain broth can’t match (see the FAQ for details). A little cornstarch slurry at the end transforms those juices into a rich, spoonable sauce. The result is deeply savory and clings to every bite of pork.
- Flavor built by searing the pork and sautéing aromatics
- Complexity from dry sherry, not just broth
- Perfect texture from a final thicken with cornstarch
Perfect for your monthly rotation
This recipe is designed for real life. With just 20 minutes of active prep, you get a hands-off meal that feeds a crowd or provides leftovers for days. It’s that reliable comfort food dinner you can set and forget. If you love easy pork recipes, you might also enjoy this honey garlic slow cooker pork tenderloin for another quick option.

Slow Cooker Pork Loin with Sherried Mushroom Gravy (So Tender!)
- Total Time: 380 min
- Yield: 8 servings 1x
Description
A pork loin roast gets seared, then slow-cooked for 6 hours with mushrooms, onions, and sherry until it’s fall-apart tender. The result is a rich, savory mushroom gravy that makes the whole meal.
Ingredients
For the pork:
1 (3-4 lb) boneless pork loin roast
1 tsp kosher salt
1/2 tsp black pepper
2 tbsp olive oil
For the mushroom gravy base:
4 slices thick-cut bacon, chopped
8 oz cremini or white mushrooms, sliced
1 medium yellow onion, sliced
4 cloves garlic, minced
1 tbsp fresh thyme leaves (or 1 tsp dried)
1/2 cup dry sherry
1 cup chicken broth
For the slurry:
2 tbsp cornstarch
2 tbsp water
Instructions
1. Pat the pork loin completely dry with paper towels, then season it all over with the salt and pepper.
2. Heat the olive oil in a large skillet over medium-high heat. Add the pork loin and sear for 3-4 minutes per side until deeply golden brown. Transfer the pork to your slow cooker.
3. In the same skillet, add the chopped bacon. Cook until crisp, about 5-7 minutes. Remove the bacon with a slotted spoon and add it to the slow cooker.
4. Add the sliced mushrooms and onion to the bacon fat in the skillet. Cook for 5-7 minutes, until softened and starting to brown.
5. Stir in the minced garlic and thyme until fragrant, about 30 seconds.
6. Pour in the dry sherry to deglaze the pan, scraping up all the browned bits from the bottom. Let it simmer for 1 minute.
7. Pour the entire mushroom and sherry mixture from the skillet over the pork loin in the slow cooker. Add the chicken broth.
8. Cover and cook on Low for 6 hours, until the pork reaches an internal temperature of at least 145°F and shreds easily with a fork.
9. Carefully transfer the pork loin to a cutting board and tent it with foil.
10. Turn the slow cooker to High. In a small bowl, whisk the cornstarch and water into a smooth slurry. Whisk the slurry into the hot mushroom gravy in the slow cooker. Cook for 15-20 minutes, until the gravy has thickened.
11. Slice or shred the pork and serve it smothered in the sherried mushroom gravy.
Notes
Store leftovers in the refrigerator for up to 5 days or freezer for up to 3 months. Reheat gently in a skillet over medium-low heat with a splash of water, or microwave in 30-second intervals.
Patting the pork dry before searing is essential for getting a good, brown crust.
Use dry sherry, not cooking wine, for the best flavor. If you don’t have sherry, use 1/2 cup extra broth mixed with 1 tbsp white wine vinegar.
If your gravy isn’t thick enough after adding the slurry, mix another 1 tbsp cornstarch with 1 tbsp water and whisk it in.
This recipe uses a pork loin roast, which is larger and wider than a skinny pork tenderloin. Using the correct cut is key.

Substitutions: No dry sherry? See the FAQ below for substitution options. For a different side, this chicken garlic mushroom pasta uses a similar savory flavor base.
Choosing the right pork cut
You need a pork loin, not a tenderloin (see the FAQ for the difference). Using the wrong cut will lead to dry, overcooked meat. Look for a roast that’s uniform in thickness so it cooks evenly in your slow cooker.
Pat it completely dry with paper towels before searing. This is key for a good brown crust.
The mushroom gravy base
The sliced mushrooms and onions break down over 6 hours, creating a deep, savory foundation for the gravy. Using dry sherry instead of cooking wine is non-negotiable (see the FAQ for why). The cornstarch slurry at the end turns all those flavorful juices into a rich, clingy sauce. For a thicker gravy, mix an extra tablespoon of cornstarch with water.
Essential seasonings & aromatics
Chopped bacon is your flavor starter. Rendering its fat first gives you oil to sear the pork and cook the vegetables, building layers of savory taste. Fresh thyme offers a subtle, earthy note that pairs perfectly with pork and mushrooms. If you only have dried, use one-third the amount. The garlic should be minced, not pressed, to prevent it from burning when you sauté it.
How to make slow cooker pork loin with mushroom sauce
This method is all about building layers of flavor. Follow these steps for a foolproof Slow Cooker Pork Loin with Mushroom Sauce.
Step 1: Browning for maximum flavor
- Pat the pork loin completely dry with paper towels, then season it generously with salt and pepper.
- Heat olive oil in a large skillet over medium-high heat. Add the pork loin and sear for 3-4 minutes per side until deeply golden brown.
Watch Out: Don’t crowd the skillet. If your roast is very large, brown it in two batches to get a proper sear instead of steaming it.
Step 2: Building the gravy in the skillet
- Transfer the seared pork to your slow cooker.
- In the same skillet, add the chopped bacon. Cook until crisp, then remove with a slotted spoon and add it to the crock pot.
- Add the sliced mushrooms and onion to the bacon fat. Cook for 5-7 minutes until softened and starting to brown.
- Stir in the garlic and thyme until fragrant, about 30 seconds.
- Pour in the sherry to deglaze, scraping up all the browned bits from the bottom of the pan.
Chef’s Note: Those browned bits are pure flavor gold for your gravy. Let the sherry simmer for a minute to cook off the alcohol.
Step 3: Slow cooking to perfection
- Pour the entire mushroom mixture from the skillet over the pork loin in the slow cooker.
- Add the chicken broth.
- Cover and cook on Low for 6 hours. The pork is done when it reaches an internal temperature of at least 145°F and shreds easily with a fork.
Step 4: Finishing & serving
- Carefully transfer the pork loin to a cutting board and tent it with foil.
- Make a slurry by whisking the cornstarch with water until smooth.
- Turn your slow cooker to High. Whisk the slurry into the hot mushroom gravy and cook for 15-20 minutes until thickened.
- Slice or shred the pork, then serve it smothered in the sherried mushroom gravy.
This rich gravy would also be fantastic tossed with a garlic mushroom pasta on another night.
Serving, storage & troubleshooting
Best ways to serve
The rich, savory gravy is the star here. Pour it generously over creamy mashed potatoes, which soak up every drop. For a lighter side, try buttered egg noodles or a simple green salad with a sharp vinaigrette to cut through the richness.
If you’re serving a crowd, shred the pork right in the slow cooker and keep it warm. Leftover gravy is fantastic on its own. I’ve tossed it with fried pork chops for a quick second meal.
Storing & reheating leftovers
Let the pork and gravy cool completely before storing them together in an airtight container. This keeps the meat moist.
| Storage Method | Duration | Notes |
|---|---|---|
| Refrigerator | Up to 5 days | Store in a single container. |
| Freezer | Up to 3 months | Freeze gravy and pork together in a sealed bag. |
Reheat gently to preserve texture. Use a skillet over medium-low heat with a splash of water or broth, covered, until steaming. In the microwave, use 30-second intervals, stirring between each.
Common issues & how to fix them
Even simple recipes can hit snags. Here’s how to solve the most common ones.
| Problem | Solution |
|---|---|
| Pork is dry or tough. | You likely overcooked it. Next time, check the internal temperature at 5 hours on Low. It should be 145°F and shred easily. |
| Gravy is too thin. | Make sure your slow cooker is on High when adding the cornstarch slurry. Let it bubble for a full 15-20 minutes to thicken properly. |
| The dish looks bland. | Don’t skip searing the pork or browning the mushrooms and onions. That brown crust builds the deep flavor base for your gravy. |
| Not enough sauce. | If your roast was very lean, you might have less juice. Add an extra 1/2 cup of broth at the start, or thin the finished gravy with a splash more broth. |
Your slow cooker pork loin with mushroom sauce questions, answered
What is the difference between a pork loin and a pork tenderloin?
A pork loin is a large, wide roast, usually 3-4 pounds. A pork tenderloin is a skinny strip, about 1 pound. For this recipe, you need the bigger roast. It braises perfectly over 6 hours, while a tenderloin would overcook and dry out in that time.
Do you have to use sherry in this recipe?
Yes, for the best flavor. Dry sherry adds a nutty, complex backbone to the mushroom gravy that broth alone can’t match. If you must skip it, use 1/2 cup extra broth with 1 tablespoon of white wine vinegar. Avoid “cooking wine,” which is too salty and won’t provide the same depth.
How do I cook a pork loin in a slow cooker?
Sear it first in a hot skillet for 3-4 minutes per side to build flavor. Place it in your crock pot with the sautéed mushrooms, onions, garlic, and bacon. Add sherry and broth, then cook on Low for 6 hours until the internal temperature reaches at least 145°F. See the troubleshooting section above for more details.
Make this slow cooker pork loin with mushroom sauce for Sunday dinner
This recipe is worth making for its flavor and texture. The sear creates a crust, the sherry builds the gravy, and the long braise gives you pork that shreds perfectly with a fork.
I always make a double batch of the gravy. It’s that good. You should try it this weekend.
