The Essential Components: Achieving Perfection
While the recipe itself is straightforward, understanding the role of each component can elevate your open-faced roast beef sandwich from good to unforgettable. Let’s delve into the key elements:
The Roast Beef: Thin Slices, Big Flavor
The star of the show, of course, is the roast beef. For the best experience, aim to slice your leftover roast beef as thinly as possible. Thin slices not only make the meat more tender and easier to eat but also allow it to absorb the warm gravy more effectively, enhancing every bite. If your roast beef is cold, slicing it thinly might be easier. You can use a sharp chef’s knife or even an electric slicer for restaurant-quality thinness. Once sliced, the beef needs to be gently warmed through. You can do this by simmering it briefly in a small amount of beef broth or by lightly sautéing it in a pan until just heated, ensuring it doesn’t dry out.
The Bread: The Foundation of Comfort
The choice of bread might seem minor, but it’s crucial for the overall experience. Traditional open-faced sandwiches often feature classic white bread, which provides a soft, absorbent base for the gravy. However, feel free to experiment with other options. A hearty sourdough, a soft brioche, or even a robust rye bread can add different dimensions of flavor and texture. Toasting the bread lightly can prevent it from becoming too soggy under the gravy while adding a pleasant crunch. Some prefer a soft, untoasted slice for ultimate comfort, allowing it to become a delightful vehicle for the savory toppings. Consider what texture you prefer: a slight crispness or a melt-in-your-mouth softness.
The Gravy: The Unifying Element
Perhaps the most critical component after the beef itself is the gravy. A good gravy binds everything together, infusing the entire dish with moisture and flavor. If you’re lucky enough to have leftover gravy from your original roast, that’s undoubtedly the best choice, as it will perfectly complement the beef. Its rich, meaty essence will bring the dish full circle. However, if no homemade gravy is available, don’t despair! High-quality store-bought brown gravy can be an excellent substitute. Look for brands that offer a robust, savory flavor. Alternatively, you can whip up a quick pan gravy using beef broth, a roux (butter and flour), and seasonings. The key is to ensure the gravy is piping hot when served, warming the beef and bread to perfection.

Ingredients
- 1 lb leftover roast beef, thinly sliced
- 4 slices hearty bread (white, sourdough, or brioche work well)
- 1 cup brown gravy (homemade or good quality store-bought)
Instructions
-
Begin by preparing your leftover roast beef. Slice it as thinly as possible against the grain for maximum tenderness. Gently warm the sliced roast beef. You can do this in a microwave, in a skillet over low heat with a splash of beef broth, or by immersing it briefly in hot gravy. Be careful not to overcook or dry out the meat.
-
While the beef is warming, heat your gravy in a saucepan over medium heat until it’s simmering gently and thoroughly hot. If desired, lightly toast your bread slices.
-
To assemble, place a generous portion of the warmed roast beef slices on top of each slice of bread. Spoon a liberal amount of the hot gravy over the beef, ensuring every piece is well-coated. Serve immediately while hot and enjoy!

Serving Suggestions and Customizations
While a hot open-faced roast beef sandwich is a complete meal in itself, pairing it with classic side dishes can elevate the experience. Creamy mashed potatoes are a natural companion, perfect for soaking up any extra gravy. Steamed or roasted green vegetables like broccoli, asparagus, or green beans add a fresh counterpoint to the rich flavors. A simple side salad can also provide a refreshing crunch. For a heartier meal, consider serving with a side of crispy potato wedges or a warm corn casserole.
Feeling creative? Don’t hesitate to customize your sandwich!
- **Add Cheese:** A slice of provolone or Swiss cheese melted over the warm beef before adding gravy takes this sandwich to a new level of decadence.
- **Caramelized Onions:** Sweet, savory caramelized onions can add a depth of flavor that pairs beautifully with roast beef.
- **Horseradish Sauce:** For those who enjoy a little kick, a dollop of creamy horseradish sauce on the bread before the beef provides a delightful zing.
- **Different Herbs:** A sprinkle of fresh parsley or chives adds a touch of freshness and color.
- **Garlic Bread:** Instead of plain bread, use garlic bread for an extra layer of flavor.
These simple additions can transform the sandwich into a gourmet experience while still maintaining its comforting essence.
Storage and Reheating Tips
If you happen to have any leftover open-faced roast beef sandwiches (though it’s unlikely!), it’s best to store the components separately if possible. Keep the roast beef and gravy in airtight containers in the refrigerator for up to 3-4 days. The bread is best stored at room temperature or can be frozen separately. When ready to enjoy again, gently reheat the beef and gravy on the stovetop or in the microwave until thoroughly warm. Toast fresh bread and assemble just before serving for the best results.
Avoid assembling the sandwiches and then storing them, as the bread tends to get soggy and the texture won’t be as enjoyable upon reheating. By keeping the elements separate, you ensure that each component retains its optimal texture and flavor for a delightful second serving.
