Tips for success

For the most flavorful result, use full-fat cowboy butter and let it melt slowly over the roast. If you don't have cowboy butter, you can make a quick version by mixing softened butter with minced garlic, chopped parsley, and a pinch of salt.

The butter not only adds flavor but also helps create a silky gravy as it blends with the seasoning packets and pork juices.

To thicken the gravy, remove the roast and whisk 2 tablespoons of cornstarch with 2 tablespoons of cold water, then stir into the slow cooker juices and cook on high for 10-15 minutes until thickened.

Alternatively, serve the pork with a slotted spoon and use the juices as a light sauce. Leftover gravy can be refrigerated and used to moisten leftovers.

Variations

Spicy Kick: Add 1 teaspoon of red pepper flakes or a diced jalapeño to the seasoning mix for a spicy twist. The heat balances the richness of the butter and gravy. Serve with extra hot sauce on the side.
Beef Version: Swap the pork for a beef chuck roast. Cook on low for 8-10 hours until fork-tender. The seasoning packets work equally well with beef, creating a savory pot-roast-style dish. Serve over mashed potatoes.
Creamy Gravy: After shredding the pork, stir in 1/2 cup of heavy cream or sour cream to the gravy for a creamy, tangy sauce. This works especially well if you prefer a richer, more indulgent dish. Adjust seasoning with salt and pepper.
Vegetable Add-In: Add 2 cups of baby carrots and 2 chopped onions to the bottom of the slow cooker before placing the pork on top. The vegetables will cook in the juices and become tender, absorbing the flavors. Serve the vegetables alongside the pork.

Storage and make-ahead

Fridge: Store leftover pork and gravy in an airtight container in the refrigerator for up to 4 days.
Freezer: Freeze the cooked pork and gravy in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheat: Reheat gently on the stovetop over medium-low heat, adding a splash of broth or water if needed.

Store leftover pork and gravy in an airtight container in the refrigerator for up to 4 days. Keep the buttered noodles separate to prevent them from becoming soggy. Reheat gently on the stovetop or in the microwave, adding a splash of broth or water if the gravy has thickened too much.

This recipe is ideal for meal prep. Cook the pork up to 2 days ahead, shred it, and store it in the gravy in the refrigerator. Reheat gently on the stovetop or in the microwave.

The flavors meld and deepen overnight, making leftovers even more delicious. You can also freeze the cooked pork and gravy for up to 3 months.

Serving ideas

Serve the shredded pork over a generous bed of warm buttered egg noodles, spooning the rich gravy over the top. The noodles soak up the savory juices, making each bite comforting and satisfying.

For a lighter option, serve over cauliflower rice or alongside steamed green beans. A sprinkle of fresh parsley or chives adds a pop of color and freshness.

This dish also works well in sandwiches or tacos. Pile the pork onto soft rolls with a little gravy for a juicy pulled-pork sandwich, or serve in warm tortillas with pickled onions and a drizzle of the gravy. The leftovers are versatile and can be repurposed for lunches throughout the week.

Frequently asked questions

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

Yes, pork shoulder or pork butt are excellent alternatives. They have more fat and connective tissue, which makes them even more tender after slow cooking. Adjust the cooking time: shoulder may need 9-10 hours on low. Pork loin is leaner and may dry out, so it is not recommended.

What is cowboy butter and can it be substituted?

Cowboy butter is a compound butter made with garlic, herbs, and sometimes spices. It adds richness and flavor to the roast. If unavailable, use 4 tablespoons of salted butter mixed with 1 teaspoon garlic powder and 1 teaspoon dried parsley. This will still provide a similar buttery, herby flavor.

How can the gravy be thickened?

If the gravy is too thin, remove the pork and whisk 2 tablespoons of cornstarch with 2 tablespoons of cold water. Stir the slurry into the slow cooker juices and cook on high for 10-15 minutes until thickened. Alternatively, simmer the juices on the stovetop to reduce and concentrate the flavor.

Can this recipe be cooked on high instead of low?

Yes, the roast can be cooked on high for 4-5 hours instead of low for 8 hours. The result will be similar, but the meat may be slightly less tender. Always check for doneness by ensuring the pork reaches at least 145°F (63°C) and shreds easily.

What can be served with this pork besides noodles?

The pork pairs well with mashed potatoes, rice, polenta, or crusty bread to soak up the gravy. Steamed vegetables like green beans or broccoli add color and balance. For a low-carb option, serve over cauliflower rice or alongside a simple green salad.
