If you love classic roast beef sandwiches loaded with melted cheddar, this slow cooker version brings all the comfort of a takeout favorite right into your kitchen. The chuck roast cooks low and slow until it becomes incredibly tender, soaking up the savory sauce as it simmers for hours. Once shredded, the beef is piled onto soft onion rolls and draped with warm cheddar cheese sauce. It’s simple, satisfying, and makes the kind of meal everyone will want seconds of.
This recipe is inspired by the well-known sandwich that combines shredded beef, tangy sauce, and creamy cheese. But making it at home lets you control the flavor, adjust the seasoning, and create a fresher, richer version—all with minimal effort.
Why You’ll Love This Recipe
Because it’s made in the slow cooker, the chuck roast breaks down beautifully and absorbs every layer of seasoning. The meat turns juicy and fork-tender while the sauce builds a deep savory flavor. And when you top everything with warm cheddar sauce and serve it on toasted onion rolls, you get a sandwich that feels hearty, comforting, and completely stress-free to prepare.
It’s also a great option for game days, busy weeks, or casual family dinners. Once the roast is in the slow cooker, you can forget about it until serving time.
Ingredients
- 2–3 pound chuck roast
- 2 teaspoons dried minced onion
- 1 teaspoon Montreal steak seasoning
- 1 tablespoon Worcestershire sauce
- 1½ cups Arby-style sauce (plus extra for topping)
- 1 cup cheddar cheese sauce
- 6 onion rolls
How to Make Slow Cooker Beef and Cheddar Sandwiches
1. Add the Beef
Place the chuck roast into the bottom of a 6-quart slow cooker.
2. Season the Roast
Sprinkle dried minced onion and Montreal steak seasoning evenly across the top.
3. Add the Liquids
Pour the Worcestershire sauce over the roast, followed by the Arby-style sauce. These ingredients will create a flavorful base that the beef cooks in for hours.
4. Slow Cook
Cover and cook on LOW for 8 hours or HIGH for 4 hours. The roast should be tender enough to shred easily with two forks.
5. Shred the Beef
Once the beef is done, shred it directly in the slow cooker and mix it with the warm sauce. Switch the slow cooker to WARM so everything stays heated for serving.
6. Heat the Cheese Sauce
Warm the cheddar cheese sauce in the microwave or on the stovetop until smooth and pourable.
7. Assemble the Sandwiches
Load the shredded beef onto onion rolls, spoon the warm cheddar cheese sauce over the top, and finish with extra Arby-style sauce if you like.
Tips for the Best Beef and Cheddar Sandwiches
Toast the rolls: This gives structure and adds a bit of crunch.
Use fresh cheddar cheese sauce: You can also melt shredded cheddar if you prefer.
Add toppings: Tomato slices, lettuce, and a swipe of mayo give the sandwich a deluxe feel.
Go spicy: If you want extra heat, use a spicy BBQ sauce or add crushed red pepper into the meat mixture.
Make sliders: Swap the onion rolls for soft dinner rolls to create crowd-friendly mini sandwiches.

Frequently Asked Questions
Can I use a different cut of beef?
Chuck roast works best, but brisket or bottom round can also be used.
Can I cook it longer?
Yes—slow and low always improves tenderness. LOW for 10 hours works well for tougher roasts.
Can I make it ahead?
Absolutely. Store the shredded beef separately from the cheese sauce and assemble the sandwiches when ready to serve.
Can I skip the onion rolls?
You can use any bun—brioche, hamburger, sesame seed, or slider rolls all work well.
