This mushroom gravy slow cooker pork butt is the perfect example of why you don't always have to make slow cooker pulled pork! Change up the flavor and how you serve this affordable cut of pork with a decadent mushroom gravy loaded with whole mushrooms! You can also make Instant Pot pork butt if you want a faster method to cook it.
Pork Butt in the Slow Cooker
To prepare this pork butt, begin by patting the pork roast dry with some paper towels to remove excess moisture. Once this is done, season both sides of the roast with salt and pepper.
You can skip this step if you want but browning it really does add flavor! However, if you are in a hurry, just put the roast in as-is.
Sear the roast in a frying pan with oil on both sides until brown, then place in the slow cooker. Place onions and mushrooms on top.
Whisk together the broth and the gravy until smooth then pour over top. If you can't find mushroom broth you can use pork broth or chicken. You can also customize the gravy packets to your favorite flavors as well!
Cook until the roast falls apart, around 8-10 hours on low all day. You have to cook it until the connective tissues dissolve and the fat renders out, or it will be tough. This cut of meat has to be cooked low and slow, or pressure cooked.
Serve over mashed potatoes, or just by itself (it's a great low carb option!). This reheats very well and can be frozen and reheated at a later date. Just make sure to freeze it in a freezer-safe container and eat it within 3 months.
