Preparation Method 🥪
Step 1: Prepare the Savory Broth
In a medium saucepan, combine:
- Beef broth
- Onion soup mix
Place over medium-high heat and bring to a gentle boil. Stir well until the soup mix fully dissolves.
This broth becomes the secret flavor booster for the roast beef.
Step 2: Warm the Roast Beef
Once the broth begins boiling:
- Remove the pot from the heat
- Add the sliced deli roast beef directly into the hot broth
Let the beef sit in the warm liquid for 3–5 minutes.
Important Tip:
Do not continue boiling the meat because deli roast beef can become tough if overheated. The residual heat gently warms the beef while keeping it tender and juicy.
Step 3: Toast the Buns
Slice the sandwich buns in half.
You can:
- Toast them in a skillet with butter
- Bake them lightly in the oven
- Use an air fryer for extra crispness
Toasting prevents the buns from becoming soggy once the sauces are added.
Step 4: Heat the Cheese Sauce
Warm the cheddar cheese sauce in a small saucepan or microwave until smooth and creamy.
For extra flavor, add:
- A pinch of garlic powder
- A splash of milk
- A little paprika
Step 5: Build the Sandwiches
Layer the sandwiches in this order:
- Bottom bun
- Warm roast beef
- Generous cheddar cheese sauce
- Drizzle of barbecue sauce
- Optional toppings
- Top bun
Serve immediately while hot and melty.
