Tips for success

For the best flavor, sear the chuck roast in a hot skillet with a little oil until browned on all sides before adding it to the slow cooker.

This adds a rich crust and deepens the overall taste. If you're short on time, skip the searing — the slow cooker will still produce a delicious meal.

When shredding the beef, use two forks to pull it apart into bite-sized pieces. Remove any large pieces of fat or gristle as you go. If you have leftovers, store them with the gravy to keep the meat moist. The flavors continue to develop overnight, making it even better the next day.

Variations

Mushroom and Guinness: Add 8 oz sliced cremini mushrooms along with the onions. The mushrooms soak up the Guinness and add an earthy depth. Sauté them briefly before adding to the slow cooker for extra flavor.
Spicy Stout Roast: Add 1-2 chopped chipotle peppers in adobo sauce and a teaspoon of smoked paprika to the gravy. The smoky heat balances the malty stout and adds a kick.
Herb and Garlic: Add 4 cloves of smashed garlic and a few sprigs of fresh thyme or rosemary to the slow cooker. The herbs infuse the gravy with aromatic notes that complement the beef.
Onion Soup Mix: Replace the brown gravy with 1 packet of onion soup mix and 2 cups of beef broth. This adds a savory, salty flavor and thickens the sauce as it cooks.

Storage and make-ahead

Fridge: Store in an airtight container in the refrigerator for up to 4 days. Reheat gently with a little extra broth to keep moist.
Freezer: Freeze in an airtight container for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheat: Reheat gently on the stovetop or in the microwave, adding a splash of beef broth or water if needed to loosen the gravy.

Store any leftover shredded beef and gravy in an airtight container in the refrigerator for up to 4 days. Keep the beef and gravy together to prevent the meat from drying out.

Reheat gently on the stovetop or in the microwave, adding a splash of beef broth or water if needed to loosen the gravy.

This recipe is perfect for making ahead. Cook the roast up to 2 days in advance, then cool, cover, and refrigerate. When ready to serve, reheat the beef and gravy gently on the stovetop.

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

Serving ideas

Serve the shredded beef piled onto toasted brioche slider buns for a fun, handheld meal. The soft buns soak up the rich gravy, while the tender beef and sweet pearl onions are a perfect match. Add a side of crispy fries or a simple green salad to round out the meal.

For a more traditional presentation, serve the beef and gravy over mashed potatoes or egg noodles. The creamy starch soaks up the flavorful gravy, making every bite comforting.

Garnish with fresh parsley if desired, though the dish is delicious on its own. Extra gravy on the table is always welcome.

Frequently asked questions

Can this be made ahead of time?

Yes, this recipe is ideal for making ahead. Cook the roast as directed, then cool and refrigerate for up to 2 days. Reheat gently on the stovetop, adding a splash of broth if needed. The flavors meld and deepen, making it even more delicious the next day.

Can this be frozen?

Absolutely. The cooked beef and gravy freeze well for up to 3 months. Store in an airtight container or freezer bag, removing as much air as possible. Thaw in the refrigerator overnight before reheating. The texture remains tender and flavorful.

What can be used instead of Guinness?

Any dark stout or porter will work well. For a non-alcoholic version, use a non-alcoholic stout or replace the beer with beef broth. Keep in mind that the beer adds depth and a slight bitterness; using broth will result in a milder flavor.

Is it necessary to sear the beef first?

Searing is optional but recommended. It adds a rich brown crust and enhances the flavor of the final dish. If you're short on time, you can skip it — the slow cooker will still produce a tender and tasty roast, though the gravy may be slightly less complex.

How can the gravy be thickened?

If the gravy is too thin after cooking, remove the beef and onions, then whisk in a slurry of 1 tablespoon cornstarch mixed with 2 tablespoons cold water. Cook on high for 15-20 minutes until thickened. Alternatively, simmer the gravy on the stovetop to reduce it.

Guinness Onion Brown Gravy Chuck Roast

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

Ingredients

3 1/2 lb beef chuck roast
1 cup pearl onions, peeled
12 fl oz Guinness stout
2 cups rich brown gravy
4 tbsp unsalted butter
8 brioche slider buns, toasted

Instructions

Place the beef chuck roast in the center of the slow cooker. Scatter the pearl onions around the roast. Pour the Guinness stout over everything. Add the rich brown gravy, then dot the top with the butter.
Cover the slow cooker and cook on low for 8 to 10 hours, or on high for 4 to 5 hours, until the beef is fork-tender and easily shreds. Let it rest for 3 minutes before slicing.
Once the roast is tender, remove it to a cutting board. Let it rest for at least 3 minutes. Then shred the beef with two forks, discarding any large fat pieces.
Skim excess fat from the surface of the gravy in the slow cooker. Taste the gravy and adjust seasoning with salt and pepper if needed.
Toast the brioche slider buns in a toaster or under the broiler until golden and crisp.
Pile the shredded beef onto the bottom halves of the toasted buns. Spoon a generous amount of the Guinness onion gravy over the beef, then top with the other half of each bun.
