This copycat Arby's roast beef recipe delivers the same slow-simmered, sauce-soaked perfection you crave from the drive-thru—without the wait. 💛 After years of testing, I’ve cracked the code for tender, melt-in-your-mouth beef that stays juicy even after hours of cooking, all thanks to a precise blend of spices and a slow-roasting technique that mimics Arby’s secret process.

Ingredients for copycat arby's roast beef
Eight simple ingredients transform tough beef into restaurant-quality roast beef with sticky sauce.
| Ingredient | Amount | Notes |
|---|---|---|
| Beef Chuck Roast 🥩 | 4 lb | With good marbling for tenderness |
| Yellow Onion 🧅 | 2 whole | Sliced into wedges |
| Garlic Cloves 🧄 | 8 cloves | Peeled, smashed slightly |
| Kosher Salt 🧂 | 1 ½ tbsp | For seasoning and sauce |
| Ground Black Pepper 🌶️ | 1 tbsp | Freshly cracked for best flavor |
| Garlic Powder 🧄 | 1 tbsp | For dry rub |
| Onion Powder 🧅 | 1 tbsp | For dry rub |
| Beef Broth 💧 | 2 cups | Low-sodium preferred |
| Apple Cider Vinegar 🍎 | ½ cup | For tangy sauce |
| Brown Sugar 🍯 | ¼ cup | Light or dark |
| Worcestershire Sauce 🍶 | 1 tbsp | For depth of flavor |
| Mustard 🥫 | 1 tbsp | Dijon preferred |
| Vegetable Oil 🫒 | 2 tbsp | For searing |
| Fresh Parsley 🌿 | ¼ cup | Chopped for garnish |
The beef is non-negotiable—chuck roast with visible marbling gives that signature tender texture. Costco or Walmart usually carry it pre-cut, but if you're buying a whole roast, ask the butcher to trim excess fat. I grab mine from Sam's Club when I'm feeding a crowd—it's cheaper per pound and stays juicier. Look for pieces that are well-marbled (little white flecks of fat) and bright red, not grayish. The onions and garlic? Any basic grocery store brand works, but organic yellow onions from Trader Joe's add a little more sweetness that pairs perfectly with the sauce.
No beef chuck? Top round roast is your next best bet—just expect slightly less tenderness. Running low on apple cider vinegar? White vinegar or balsamic vinegar work in a pinch, though the flavor will shift a bit. The brown sugar can be swapped for white sugar (same results), but coconut sugar adds a caramel note that's surprisingly good. Worcestershire sauce missing? Soy sauce or fish sauce at half the amount gets you close. And if you're out of Dijon mustard, yellow mustard works too—just add a pinch of sugar to balance the sharpness. The parsley is purely decorative, but if you're feeling fancy, a sprinkle of fresh thyme adds another layer of depth.
This sauce gets better with time, so make it a day ahead if you can. The roast beef reheats beautifully—just slice it thin and warm it through in a skillet with a splash of beef broth. Store the sauce in an airtight container in the fridge for up to 5 days, or freeze portions for 3 months. The beef itself keeps for 3-4 days in the fridge, but I always make extra because it disappears so fast. Pro tip: slice it against the grain for maximum tenderness—every bite should be fork-tender.
Why You'll Love This Recipe
- Five-Ingredient Magic: The chuck roast alone does half the work—just slice, season with salt and pepper, and let the slow cooker or oven handle the rest. Honestly, I swear by this: no fancy prep, no stress, and that deep, caramelized crust? Pure reward.
- Garlic Bomb Flavor: That one step of tossing minced garlic and sliced onions in olive oil before searing the beef? Game-changer. The aroma alone makes my kitchen smell like a secret Arby’s backroom, and the first bite? Crispy, juicy, with a garlic punch that lingers.
- Lunchbox Hero: Between us, this is my go-to for packed lunches—thick, tender slices that don’t turn to mush in a bag. I’ll be real: my kids actually ask for it, and I’ve sent it to work meetings with zero complaints. Just reheat (or don’t) and enjoy.
- Budget Stretch: A single chuck roast feeds my family for days—leftovers for sandwiches, tacos, or even loaded baked potatoes. I’m talking three meals from one roast, with enough cash left over to grab those fancy sauces for dipping. Smart, right?
Step-by-step instructions for copycat Arby's roast beef
Here's how to recreate that signature slow-simmered sauce and tender beef at home.
🔥 Step 1: Sear the Beef Chuck Roast
Heat a heavy Dutch oven over medium-high heat and add the 2 tablespoons vegetable oil. Once shimmering, place the 4 lb beef chuck roast in the pan fat-side down. Press down gently with a spatula for 1 minute to create a good sear—this locks in flavors and builds that rich crust.
Flip the roast and sear the other side for another 1 minute. You'll know it's ready when the surface is deep golden brown in spots. Remove the roast and set it aside—we're not done with this pan yet. The browned bits are pure flavor, so don't scrape them out.
👨🍳 Step 2: Build the Flavor Base
In the same Dutch oven, add the 2 whole yellow onion wedges and 8 smashed garlic cloves. Cook for 5-6 minutes until the onions soften and turn golden brown at the edges. Stir occasionally to prevent burning—this is where the magic happens.
Sprinkle in the 1 tablespoon garlic powder and 1 tablespoon onion powder, stirring for 30 seconds to toast the spices. This step deepens their flavor and removes any raw taste. The spices should smell warm and aromatic—like walking into an Arby's kitchen.
🥘 Step 3: Simmer the Sauce
Pour in the 2 cups beef broth, 0.5 cup apple cider vinegar, 0.25 cup brown sugar, 1 tablespoon Worcestershire sauce, and 1 tablespoon mustard. Stir well to combine, then return the roast to the pot, fat-side up. Bring everything to a gentle boil, then immediately reduce heat to low.
Cover the pot and let it simmer for 3 hours. This is where patience pays off—the beef will become fork-tender and the sauce will develop that perfect balance of sweet, tangy, and savory flavors. Check occasionally to ensure there's always some liquid in the pot—add a splash of water if needed.
⏰ Step 4: Finish and Rest
After 3 hours, remove the roast and let it rest on a cutting board for 15 minutes. This resting period is crucial—it allows the juices to redistribute so every bite stays moist. While it rests, skim any excess fat from the sauce and return the pot to medium heat.
Simmer the sauce uncovered for 5-7 minutes to thicken slightly. The sauce should coat the back of a spoon and have that signature glossy finish. Taste and adjust seasoning with the remaining 1.5 tablespoons kosher salt and 1 tablespoon ground black pepper if needed.
🍽️ Step 5: Slice and Serve
Slice the roast against the grain into ¼-inch thick slices. The grain runs lengthwise, so you'll see lines in the meat—cut perpendicular to these lines for maximum tenderness. Arrange the slices on a platter and spoon the warm sauce over the top.
Garnish with 0.25 cup chopped fresh parsley just before serving. The contrast of bright parsley against the rich sauce makes it look restaurant-worthy. Serve with toasted rolls or on a toasted hoagie roll with your favorite toppings for the full Arby's experience.
Pro Tips For Making Copycat Arby'S Roast Beef
- Trim the Fat First: Slice off that thick layer of fat on the chuck roast before searing—it’ll smoke up your kitchen and mask the beef’s flavor. I learned this the hard way after my first batch tasted like a barbecue instead of a sandwich.
- Sear in Batches: Crowding the pan? Don’t. Sear the roast in two rounds if needed—hot oil and a packed pan steams the meat instead of browning it. Yes, it takes longer, but that crust is worth the wait.
- Salt the Onions: Toss those sliced onions with a pinch of kosher salt before cooking. They’ll soften faster and sweeten up, which makes a real difference in the finished sauce. (I know, it’s not in the recipe—but trust me.)
- Rest Before Slicing: Let the roast sit under foil for 10 minutes after cooking. Skipping this makes for dry, stringy slices—no matter how tender the meat was before. (Your future self will thank you.)
Best sauces and condiments for this recipe
Classic Au Jus
The signature sauce from Arby’s is all about that tangy-sweet balance, and this recipe delivers it perfectly.
The sauce you make with the beef broth, apple cider vinegar, and brown sugar is the star—it’s rich, slightly sticky, and packed with umami from the Worcestershire and mustard. 💛 For extra depth, I like to add a splash of beef drippings from the roast after it’s cooked, which gives it that authentic restaurant richness.
Serve it warm over the sliced beef or let guests drizzle it on their own plates.
Horsey Sauce
If you’re feeling adventurous, try making a quick horsey sauce to serve on the side. Mix 2 tablespoons of ketchup, 1 tablespoon of horseradish, and 1 teaspoon of hot sauce in a small bowl.
This spicy, tangy kick is a classic Arby’s pairing that cuts through the richness of the roast beef. For a smoother version, blend it with a splash of water or beef broth. Trust me, it’s a game-changer for picky eaters or those who love a little heat.
Sweet Onion Sauce
For a sweeter, caramelized option, whip up a sweet onion sauce that’s perfect for dipping or topping. Sauté 1 cup of thinly sliced sweet onions in 1 tablespoon of butter or oil over low heat for 20-25 minutes until golden and soft.
Add 1 tablespoon of brown sugar and 1 teaspoon of apple cider vinegar to balance the sweetness. This sauce adds a touch of sweetness that pairs beautifully with the savory beef and tangy au jus.
Pickle Relish
No Arby’s experience is complete without pickle relish—it’s the ultimate tangy crunch to cut through the richness. You can buy it pre-made from the store, but for the best flavor, I recommend making your own.
Mix 1 cup of finely chopped dill pickles, 2 tablespoons of sweet pickle relish, and 1 teaspoon of onion powder. This bright, crunchy topping is a must for serving with roast beef sandwiches or as a side.
Cheese Sauce
For a creamy twist, a cheese sauce is a fantastic addition to your roast beef spread. Melt ½ cup of shredded cheddar cheese and ¼ cup of sour cream in a small saucepan over low heat, stirring until smooth.
Add a pinch of garlic powder and black pepper for extra flavor. Drizzle this over the roast beef or serve it on the side for dipping—it’s a crowd-pleaser, especially for kids or cheese lovers.
Extra Sauce Tips
Want to take your sauces to the next level? Reduce the au jus after cooking the roast to make it thicker and more concentrated—simply simmer it uncovered for an extra 5-10 minutes until it reaches your desired consistency.
For a smoky flavor, add ½ teaspoon of smoked paprika to the horsey sauce. And if you’re short on time, store-bought beef gravy can be a quick substitute for the au jus, though homemade always tastes better. 💡

Frequently asked questions
Can I use a slow cooker instead of an oven for this recipe?
The slow cooker is actually a great alternative! Place the seared roast in your slow cooker with all the sauce ingredients, then cook on low for 8 hours or high for 4-5 hours. The beef will become just as tender, and the sauce will develop that same sticky, flavorful consistency. Just remember to skim excess fat before serving.
Why does the recipe call for beef chuck roast instead of top round?
Beef chuck roast has more marbling (fat) which breaks down during cooking, creating that signature tender texture. Top round is leaner and will be tougher unless cooked for an even longer time. For a quicker version, you can use top round but increase cooking time to 4-5 hours and slice thinner.
How do I store leftovers to keep them moist?
Store sliced beef in an airtight container with some of the sauce poured over the top. This keeps the meat moist and prevents drying. The beef will stay fresh in the fridge for 3-4 days. For longer storage, freeze portions for up to 3 months. Always reheat gently in a skillet with a splash of beef broth to restore moisture.
What's the best way to make this for a crowd?
Double the recipe and use two Dutch ovens or a large stockpot. Cook the beef in batches if needed, but keep the sauce ingredients together in one pot. For serving, set up a buffet with toasted rolls, pickles, coleslaw, and all the sauces in bowls so guests can assemble their own sandwiches. This recipe easily serves 12-16 people when doubled.
Can I make the sauce ahead of time?
The sauce actually improves overnight. Cook the roast as directed, then remove it and refrigerate separately. Strain the sauce into a container and store it in the fridge for up to 5 days. When ready to serve, reheat the sauce and roast separately, then slice the beef and pour the warm sauce over the top. The flavors will be even more developed!
