1 tbsp soy sauce
1 tbsp brown sugar
1 tsp garlic powder
1 tsp onion powder
½ tsp black pepper
½ tsp smoked paprika
1 small onion, thinly sliced
For the Cheddar Sauce:
2 tbsp butter
2 tbsp all-purpose flour
1 cup whole milk
1 ½ cups shredded sharp cheddar cheese
¼ tsp salt
¼ tsp ground mustard (optional)
For Serving:
6–8 sandwich buns (brioche, hamburger, or hoagie rolls)
Pickles, caramelized onions, or jalapeños (optional)
Tools You’ll Need
Slow cooker
Medium saucepan (for cheese sauce)
Mixing spoon or whisk
Shredder or forks (for pulling beef)
Toaster or oven (for toasting buns)
Step-by-Step Instructions
Step 1: Prep the Beef
Place the sliced onions in the bottom of the slow cooker.
Add the beef roast on top.
In a small bowl, mix the beef broth, Worcestershire, soy sauce, brown sugar, and seasonings.
Pour the mixture over the beef. Cover and cook on low for 8 hours or high for 4–5 hours, until the meat is fork-tender.
Step 2: Shred the Beef
Once cooked, remove the beef from the slow cooker and shred using two forks.
Return the shredded beef to the slow cooker and stir to coat in the juices. Keep warm until ready to serve.
Step 3: Make the Cheddar Sauce
In a saucepan over medium heat, melt the butter.
Whisk in the flour and cook for 1 minute to form a roux.
Gradually whisk in the milk until smooth.
Reduce heat and stir in the shredded cheddar cheese, salt, and mustard (if using).
Continue stirring until the cheese is melted and the sauce is thick and creamy.
Step 4: Assemble the Sandwiches
Toast sandwich buns if desired.
Pile the shredded beef onto the bottom half of each bun.
Drizzle with warm cheddar cheese sauce.
Top with pickles, onions, or jalapeños if desired, and place the top bun.

Tips for the Best Sandwiches
Use a Well-Marbled Cut – Chuck roast becomes ultra-tender when slow cooked.
Toast the Buns – Helps hold the sandwich together and adds texture.
Add Extras – Try coleslaw, crispy onions, or BBQ sauce for a twist.
Double the Sauce – It’s so good, you’ll want extra for dipping!
Make It Ahead – The beef can be cooked a day in advance and reheated.
Serving Suggestions
With Fries – Classic pairing with sweet potato or curly fries.
Potato Salad or Slaw – Great contrast to the rich beef and cheese.
Pickles or Peppers – Add zing and crunch to balance the richness.
On a Platter – Serve open-faced for a casual dinner spread.
Mini Sliders – Use dinner rolls for a fun party option.
How to Store & Reheat
Storing:
Refrigerate beef and cheese sauce separately in airtight containers for up to 4 days.
Reheating:
Stovetop: Warm the beef in a skillet with a bit of its juices.
Microwave: Reheat portions of beef and sauce separately until hot.
Oven: Wrap sandwiches in foil and bake at 350°F for 10–15 minutes.
Frequently Asked Questions
- Can I use a different cut of beef?
Yes, brisket or bottom round can work well too—just adjust cooking time as needed. - Can I make it dairy-free?
Use a dairy-free cheese sauce alternative or skip the cheese and top with BBQ slaw. - What’s the best bun for this sandwich?
Brioche or hoagie rolls hold up well and add a nice texture. - Can I freeze the beef?
Absolutely. Freeze in a sealed container for up to 3 months. Thaw and reheat when needed. - Is the cheese sauce spicy?
Not at all, but feel free to add a pinch of cayenne or jalapeños for heat.
