The beef is everything here. Brisket flat cut delivers that signature tendernessāCostco or local butcher sections have the best quality. Look for good marbling and ask for 1-inch thick slices. If you can't find brisket, chuck roast works in a pinch, though it'll be slightly tougher. The marinade ingredients are all pantry staples, but Worcestershire sauce mattersāLea & Perrins is the gold standard. For the garlic and onion, fresh is ideal, but powders work if you're in a hurry. Just don't skip the apple cider vinegarāit's what gives that tangy depth.
No Worcestershire? Substitute with 1/4 cup soy sauce plus 1 tsp vinegar. Fresh garlic and onion unavailable? Double the powders, but toast them first in a dry pan for 30 seconds to deepen the flavor. The beef broth should be low-sodiumāSwanson or Pacific Foods are reliable, but homemade is even better. For the sauce, if you can't find classic horseradish sauce, mix 1 tbsp prepared horseradish with 1/4 cup mayo. The Dijon mustard adds richness, but yellow mustard in a pinch works too. The butter at the end is non-negotiableāit emulsifies the sauce and gives it that velvety finish.
Marinate the beef overnight for maximum flavorāseal in a gallon bag and refrigerate. The slow cooker does all the work, but 8 hours on low is ideal. If you're short on time, 6 hours on high works, but the texture won't be as tender. The sauce thickens as it cooks, so add a splash of water if needed. Leftovers reheat beautifullyājust add a little beef broth to loosen the sauce. Store in airtight containers for up to 5 days, or freeze for 3 months. I always make a double batchāit disappears fast around game day.

Step-by-step instructions for Arby's-style crock pot roast beef
This slow-cooked method delivers that signature Arby's flavor with tender brisket and rich, tangy sauce.
šØāš³ Step 1: Prep the Brisket and Seasoning Base
Place the 3 lb beef brisket in a large resealable bag and set aside. In a small bowl, whisk together the 0.5 cup Worcestershire sauce, 2 tbsp garlic powder, 2 tbsp onion powder, 1 tbsp black pepper, 1.5 tsp salt, 2 tbsp brown sugar, and 1 tbsp apple cider vinegar. Pour this marinade over the brisket, seal the bag, and massage it into the meat for 2 minutes to ensure even coating.
While the brisket marinates, finely mince the 6 cloves garlic and slice the 1 whole onion into thin half-moons. These will infuse the sauce with deep, aromatic flavors. Let the brisket sit at room temperature for 30 minutes before cookingāthis ensures even heat penetration during the slow cook.
š„ Step 2: Layer and Slow Cook the Brisket
Place the seasoned brisket in your 6-quart crock pot fat-side up. Arrange half of the sliced onions and minced garlic over the top, then pour in the 2 cups beef broth. The broth should come about halfway up the brisketāthis creates a flavorful bath that keeps the meat moist.
Cook on LOW for 8 hours or HIGH for 5-6 hours, until the brisket reaches an internal temperature of 195Ā°F and is fork-tender. The sauce should thicken and darken slightly as it simmers, creating that signature Arby's depth of flavor. Resist the urge to check it earlyāopening the lid releases heat and extends cook time.
š„ Step 3: Finish with Horseradish and Mustard
Once the brisket is tender, carefully remove it from the crock pot and place it on a cutting board. Skim any excess fat from the sauce (but leave about Ā¼ cup for richness) and stir in the 0.25 cup horseradish sauce and 1 tbsp Dijon mustard. The horseradish adds that signature kick while the mustard rounds out the sauce's complexity. Let the sauce simmer on LOW for 10 minutes to meld flavors.
While the sauce finishes, slice the brisket against the grain into Ā¼-inch thick slices. This ensures each bite is tender and easy to chew. Return the sliced brisket to the crock pot and toss gently to coat in the sauce. The residual heat will warm the meat through while it absorbs those final flavor layers.
ā° Step 4: Rest and Serve with Butter Finish
Let the brisket rest for 15 minutes before servingāthis allows the juices to redistribute, preventing dry slices. Just before serving, stir in the 2 tbsp butter and let it melt into the sauce, creating a glossy, velvety finish. The butter adds a subtle richness that balances the tangy horseradish and sweet broth.
Serve the roast beef on toasted sesame buns with pickles and your favorite toppings. The sauce should be thick enough to cling to the meat but still coat the back of a spoon. If it's too thick, whisk in 1-2 tablespoons of hot water to reach your desired consistency. This dish tastes even better the next day as the flavors deepen!
Pro Tips For Making Arby'S Roast Beef Recipe Crock Pot
- SEAR THE BRISKET FIRST: I learned this the hard wayāskipping the sear means flavor stuck in the pan instead of the meat. Hit that brisket with a hot skillet for 2-3 minutes per side before dumping it in the crock pot. The crust locks in juices and adds depth that Worcestershire alone canāt match.
- USE FULL-STRENGTH WORCESTER: That "reduced" or "low-sodium" Worcestershire is a trap. The real stuff has vinegar, molasses, and spices that cut through the beefās richness. Donāt water it downājust use 2-3 tablespoons straight from the bottle. Your sauce will taste like a proper marinade, not a sad afterthought.
- DONāT OVERFILL THE CROCK: Iāve seen people cram brisket in with onions until the liquid barely covers it. Thatās how you end up with tough, dry meat. Fill the pot only halfway with liquidāenough to come about 2 inches up the beef. The rest of the moisture will come from the brisket itself as it cooks.
- ADD A SPLASH OF BEER: Sounds weird, but it works: swap Ā¼ cup of the water for a light beer (lager or pale ale). The hops balance the beefās fat, and the carbonation tenderizes the meat without extra effort. Skip this, and youāre missing a chance to make the sauce richerāplus, itās an excuse to drink while you cook.

Frequently asked questions
Can I use chuck roast instead of brisket for this recipe?
Yes, but expect slightly different results! Chuck roast will be more tender but may have a slightly different texture since it's not as lean. For best results, increase the cooking time by 1-2 hours on low to ensure full tenderness. The flavor will still be delicious, though the meat might be a bit more robust than brisket's delicate texture.
How do I know when the beef is fully cooked?
Use a meat thermometer to check the internal temperatureāit should reach 195Ā°F for perfect tenderness. The beef will also pull away from the bone easily and be fork-tender. If you don't have a thermometer, cut into the thickest part: the juices should run clear, not pink.
Can I make this recipe without Worcestershire sauce?
Substitute with Ā¼ cup soy sauce plus 1 tsp vinegar for a similar umami depth. For extra flavor, add Ā½ tsp smoked paprika or 1 tsp liquid smoke to mimic Worcestershire's complexity. The dish will still taste amazingājust slightly different in profile.
Why did my sauce turn out too thin?
This usually happens if the beef didn't release enough juices during cooking. To fix it, remove the beef and simmer the sauce uncovered on medium-high heat for 5-10 minutes to reduce it. For next time, try adding 1 tbsp cornstarch mixed with 2 tbsp cold water at the end and stir until thickened.
How far ahead can I prep this for game day?
You can prep everything 2 days ahead! Cook the beef, let it cool, then refrigerate in the sauce. Reheat gently on low for 2-3 hours before serving. For extra convenience, slice the beef and store it separatelyājust toss it in the reheated sauce before serving. The flavors will actually deepen overnight!
