Tips for success

For the most tender pork, always cook on LOW rather than HIGH. The longer, gentler heat breaks down collagen more effectively, resulting in shreds that melt in your mouth.

If you’re short on time, HIGH for 5 to 6 hours works, but the texture won’t be quite as silky. Also, let the pork rest in the gravy for 10 to 15 minutes after shredding—this allows the meat to absorb the sauce and become even more flavorful.

To get the best browning and flavor, use a rich, dark gravy—homemade or a high-quality jarred version. If you have time, you can sear the pork in a hot skillet before adding it to the slow cooker, but it’s not necessary.

The slow cooker will still produce a deeply savory dish. For a thicker gravy, whisk in a cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons cold water) during the last 30 minutes of cooking, then let it simmer until thickened.

Variations

Spicy Chipotle: Add 2 chipotle peppers in adobo sauce (minced) along with the garlic, and use a spicy brown gravy or add a teaspoon of smoked paprika. The heat will complement the rich pork and mushrooms.
Herb and Onion: Scatter 1 large sliced onion over the pork before adding the mushrooms, and stir in 2 teaspoons dried thyme or rosemary. This adds a sweet, aromatic layer that pairs beautifully with the gravy.
Red Wine Gravy: Replace 1/2 cup of the gravy with dry red wine (such as Merlot or Cabernet). The wine adds depth and a slight tang that cuts through the richness. Add it with the gravy and butter.
Mushroom Lover's: Use a mix of portobello, cremini, and shiitake mushrooms for a more complex earthy flavor. Increase the total mushroom amount to 12 ounces and slice them all thickly.

Storage and make-ahead

Fridge: Store in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stovetop or microwave, adding a splash of broth if needed.
Freezer: Freeze the cooled pork and gravy in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheat: Reheat gently in a saucepan over medium-low heat, stirring occasionally, until warmed through. Add a splash of broth or water if the gravy is too thick.

Store leftover pork and gravy in an airtight container in the refrigerator for up to 4 days. The flavors will meld and deepen overnight, making it even better the next day. To reheat, warm gently in a saucepan over medium-low heat, adding a splash of broth or water if the gravy has thickened too much. You can also reheat individual portions in the microwave.

This recipe is perfect for meal prep. Cook the pork up to 2 days ahead and store it in the refrigerator, then reheat gently on the stovetop or in the slow cooker on warm.

The pork also freezes beautifully—see the freezer note below. If you want to get ahead on the day of cooking, slice the mushrooms and mince the garlic a day in advance, and have the gravy measured and ready to pour.

Serving ideas

The most classic way to serve this pork is piled high on toasted brioche slider buns, with a spoonful of extra gravy ladled over the top. The soft, buttery buns soak up the sauce, and the tender meat makes each bite a messy, delicious experience.

You can also serve it over creamy mashed potatoes, egg noodles, or a bed of polenta. The gravy acts as a sauce, so choose a base that can absorb it well.

For a lighter option, serve the pork over a bed of greens or roasted vegetables. The rich gravy pairs beautifully with bitter greens like kale or broccoli rabe. If you have leftovers, use them to make tacos, quesadillas, or a hearty sandwich with melted cheese. The possibilities are endless, and the pork is just as good cold as it is hot—try it on a salad or in a wrap the next day.

Frequently asked questions

Can this recipe be made with a different cut of pork?

Yes, you can use pork butt or pork picnic, which are both the same cut. Avoid lean cuts like pork loin or tenderloin, as they will dry out during the long cooking time. Bone-in pork shoulder also works; just add about an hour to the cooking time and remove the bone before shredding.

How long does the pork need to cook?

Cook on LOW for 8 to 10 hours, or on HIGH for 5 to 6 hours. The pork is done when it reaches an internal temperature of at least 145°F (63°C), but for the most tender shreds, cook until it reaches 190°F to 200°F (88°C to 93°C). The longer cooking time breaks down the collagen, resulting in fall-apart meat.

Can this be frozen?

Yes, this recipe freezes well. Cool the pork and gravy completely, then transfer to a freezer-safe container. Freeze for up to 3 months. Thaw overnight in the refrigerator and reheat gently on the stovetop, adding a splash of broth if needed.

Why is the gravy thin?

The pork and mushrooms release liquid as they cook, which can thin out the gravy. To thicken it, remove the pork and mushrooms, then simmer the gravy on the stovetop with a cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons cold water) until thickened. Or, let the slow cooker cook uncovered for the last 30 minutes to reduce the liquid.

Can this recipe be made gluten-free?

Yes, if you use a gluten-free brown gravy or make your own with gluten-free flour or cornstarch. Check the labels on canned gravies, as many contain wheat flour. The rest of the ingredients—pork, mushrooms, garlic, and butter—are naturally gluten-free.

Slow-Cooker Portobello Brown Gravy Pork Shoulder

Prep 10 minCook 8 hTotal 8 h 10 minServes 8

Ingredients

4 lb boneless pork shoulder roast
8 oz portobello mushroom caps, thickly sliced
2 tbsp minced garlic
2 cups rich brown gravy (canned or homemade)
4 tbsp unsalted butter, cut into pats

Instructions

Place the pork shoulder roast in the center of a 6-quart slow cooker. Scatter the sliced portobello mushroom caps over and around the roast. Sprinkle the minced garlic evenly over the top.
Pour the brown gravy over the pork and mushrooms. Dot the top with the butter pats. The gravy should come about halfway up the roast; add a splash of water if needed.
Cover the slow cooker and cook on LOW for 8 to 10 hours, or on HIGH for 5 to 6 hours, until the pork is fork-tender and shreds easily. The mushrooms will be very soft and the gravy will have darkened. Let it rest for 3 minutes before slicing.
Turn off the slow cooker. Using two forks, shred the pork directly in the pot, mixing it with the mushrooms and gravy. Let it rest for at least 3 minutes before serving so the juices redistribute.
Spoon the shredded pork and mushrooms onto toasted brioche slider buns or over mashed potatoes. Drizzle with extra gravy from the pot. Serve hot.
