Tips for success

For the best flavor, use a good-quality beef consommé. If you can't find it, beef broth works, but you may want to add a splash of Worcestershire sauce for depth.

The Vidalia onions are key—they're sweet and mild, which balances the richness of the butter and pork. If you use yellow onions, consider adding a pinch of sugar to mimic the sweetness.

Don't be tempted to cut the cooking time short. The longer the pork cooks, the more tender it becomes. If you're short on time, you can cook on HIGH for 5-6 hours, but the result won't be quite as fall-apart tender.

Also, let the pork rest for at least 10 minutes after cooking before shredding—this keeps the juices in the meat.

Variations

Add Mushrooms: Add 8 oz sliced cremini mushrooms along with the onions for an earthy, savory twist. They'll cook down and absorb the buttery jus, adding extra depth.
Cheesy Finish: After shredding, stir in 1 cup shredded Gruyère or Swiss cheese until melted. This gives the dish a French onion soup vibe and adds a creamy, nutty flavor.
Herbed Version: Add 2 sprigs of fresh thyme and 1 bay leaf to the slow cooker with the onions. Remove them before shredding for a subtle herbal note.
Spicy Kick: Add 1-2 sliced jalapeños or a pinch of red pepper flakes along with the onions for a gentle heat that balances the richness.

Storage and make-ahead

Fridge: Store leftover pork in an airtight container in the refrigerator for up to 4 days. Reheat gently with a splash of broth or water to keep it moist.
Freezer: Freeze the pork in an airtight container or freezer bag for up to 3 months. Thaw overnight in the refrigerator and reheat gently on the stovetop or microwave.
Reheat: Reheat the pork gently in a saucepan over medium-low heat, adding a splash of broth or water to loosen the sauce.

Store any leftover pork in an airtight container in the refrigerator for up to 4 days. The pork will keep well and the flavors will continue to meld. Reheat gently in the microwave or on the stovetop, adding a splash of broth or water if needed to loosen the sauce.

This dish can be made up to 2 days ahead. Cook the pork, shred it, and store it in the refrigerator in its juices. Reheat gently on the stovetop or in the microwave until warmed through. The flavor actually improves as it sits, making it a great option for meal prep or entertaining.

Serving ideas

Serve the French Onion Butter Pork Shoulder over a bed of whipped Yukon Gold mashed potatoes to soak up the delicious jus.

The creamy potatoes contrast beautifully with the rich, savory pork and caramelized onions. For a lighter option, serve it over rice, polenta, or even crusty bread to mop up every last drop.

This dish also works well in sandwiches—pile the pork onto a toasted bun and top with the onions and jus for a French onion-inspired sandwich.

It's versatile enough to be the star of a hearty dinner or a casual lunch. Garnish with fresh thyme or parsley if desired, though the flavors are already complete.

Frequently asked questions

Can this recipe be made in a Dutch oven instead of a slow cooker?

Yes, this can be made in a Dutch oven. Sear the pork shoulder on all sides in a hot Dutch oven, then add the onions, consommé, and butter. Cover and cook in a 300°F (150°C) oven for 3-4 hours, or until the pork is fork-tender. Shred and serve as directed.

What can be used instead of beef consommé?

Beef broth is the easiest substitute, but you may want to add a teaspoon of Worcestershire sauce or a splash of soy sauce to mimic the deeper flavor of consommé. Alternatively, use a combination of beef broth and a little onion soup mix, though that will add sodium.

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 shreds easily with a fork and reaches an internal temperature of at least 145°F (63°C), but it will be more tender if cooked longer.

Can the pork be frozen after cooking?

Yes, the cooked and shredded pork freezes well. Store it in an airtight container or freezer bag for up to 3 months. Thaw overnight in the refrigerator and reheat gently on the stovetop or microwave.

What side dishes go well with this pork?

This pork is delicious over mashed potatoes, polenta, egg noodles, or crusty bread. It also pairs well with roasted vegetables like carrots or green beans. The rich jus is perfect for soaking up with bread or potatoes.

French Onion Butter Pork Shoulder: 5-Ingredient Slow Cooker

Prep 10 minCook 8 hRest 10 minTotal 8 h 20 minServes 8

Ingredients

4 lb boneless Boston butt pork shoulder roast
3 medium Vidalia onions, thinly sliced
2 cups beef consommé
1 stick salted butter

Instructions

Place the pork shoulder roast in the center of a 6-quart slow cooker. Pile the sliced Vidalia onions over and around the roast. Pour the beef consommé around the base of the roast, being careful not to rinse the onions off the top.
Unwrap the stick of salted butter and place it directly on top of the seasoned roast. It will melt and baste the meat as it cooks, creating a rich, silky sauce.
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 easily shreds. The onions will caramelize and the liquid will become a savory, buttery jus. Let it rest for 3 minutes before slicing.
Transfer the roast to a cutting board and let it rest for at least 10 minutes. Using two forks, shred the pork into bite-sized pieces, discarding any excess fat. Return the shredded pork to the slow cooker and stir it into the onion-butter jus.
Serve the French Onion Butter Pork Shoulder over whipped Yukon Gold mashed potatoes, spooning plenty of the caramelized onions and buttery jus over the top. Enjoy warm.
