Add cheese
Put a slice of cheese over the beef, then add more sliced roast beef, about another 1.5 oz per sandwich, for 3 oz in total. Spoon over a generous 2–3 tbsp of gravy, press on the top half of the bun and serve straight away with potato chips, a fresh salad or another side.

Reheat and toast
To warm refrigerated sliced beef, heat it on a lightly greased griddle over medium heat just until hot, adding a slice of cheese on top so it melts. Toast the buns while the beef heats. Warm the gravy in a saucepan over low heat, stirring often, just until hot.
What is a roast beef sandwich?
A roast beef sandwich is a familiar American-style meal built around thinly sliced cooked beef in bread, often with cheese or gravy. This version makes it especially hearty by layering the beef around a slice of pepper Jack and spooning warm gravy over the filling.
The recipe works well with leftovers: the beef and gravy can be prepared ahead, then warmed while the buns are toasted.

The bun supplies most of the carbohydrates, while the roast beef contributes much of the protein. Cheese and gravy add fat, so pair the sandwich with a fresh salad or vegetables for a more balanced plate.
Choose the beef and cheese
Thin slices: roast beef that is sliced thinly is easier to fold into the bun and makes a more even stack. Fold the slices loosely rather than packing them tightly.
Pepper Jack: its gentle heat contrasts with the savoury beef and gravy. For a milder sandwich, use provolone, Havarti, smoked Gouda, cheddar or Swiss.
Warm the components gently
Beef: heat the slices on a lightly greased griddle over medium heat only until hot. Adding the cheese over the beef helps it melt without needing a separate step.
Gravy: warm it over low heat and stir often. Gentle heating keeps it ready to spoon over the sandwiches without scorching.
Build the layers
Bottom layer: start with about 1.5 oz of folded beef on each bun base, then add the cheese and the remaining beef. The cheese in the middle gives each bite a creamy layer.
Gravy finish: spoon 2–3 tbsp over the top beef layer, then press on the bun top gently. Serve promptly so the bun stays intact.
Toast the buns
Toasting adds a little crispness to the soft sesame seed buns and gives them more structure beneath the warm filling. The method calls for toasting the buns while the beef heats; use your preferred bun-toasting method.
Serve it with
Potato chips make an easy, crunchy side, while a fresh salad brings a crisp contrast to the rich gravy and cheese. Serve the sandwiches as soon as they are assembled.
Recipe notes & tips
- Fold the beef slices loosely to make a tall, easy-to-bite stack.
- Warm the gravy separately so you can control how much goes on each sandwich.
- Toast the buns while the beef heats to keep the assembly quick.
- Use medium heat for the beef and low heat for the gravy.
- Serve the sandwiches straight away after adding the gravy.
Variations
- Milder cheese: swap pepper Jack for provolone, Havarti, smoked Gouda, cheddar or Swiss.
- Extra crunch: serve with potato chips for a crisp contrast to the soft bun.
- Fresh side: add a simple salad alongside the sandwich.
- Leftover roast: use cooked roast beef you already have, sliced thinly for easy layering.
Common mistakes to avoid
- Overheating the beef: it can dry out, so warm it over medium heat only until hot.
- Boiling the gravy: it may catch on the pan, so keep it over low heat and stir often.
- Packing the beef tightly: the sandwich becomes harder to bite, so fold and stack the slices loosely.
- Adding too much gravy: the bun can become difficult to handle, so start with 2 tbsp and add more if wanted.
- Assembling too early: the bun can soften under the warm filling, so put the sandwiches together just before serving.
How to store
Keep prepared roast beef and gravy refrigerated in airtight containers until serving. Reheat the beef on a lightly greased griddle over medium heat and the gravy in a saucepan over low heat, stirring often; assemble the sandwiches just before eating.
