Experience a taste of Buffalo, New York with this classic beef on weck recipe. This sandwich combines tender slices of roast beef with the unique flavor of kummelweck rolls, all brought together with a touch of horseradish and served with a side of beef au jus for dipping.
One ingredient you might not have on hand is kummelweck rolls. These are Kaiser rolls topped with caraway seeds and coarse salt, giving them a distinctive flavor and texture. If your local supermarket doesn't carry them, you can substitute with Kaiser rolls and add your own toppings.

Ingredients for Beef on Weck Recipe
Roast beef: Thinly sliced, this is the star of the sandwich, providing rich, savory flavor.
Kummelweck rolls: Special rolls topped with caraway seeds and coarse salt, essential for the authentic taste.
Beef au jus: A flavorful broth made from beef drippings, used to warm the roast beef and for dipping.
Horseradish: Adds a spicy kick to the sandwich, balancing the richness of the beef.
Technique Tip for This Recipe
To ensure your roast beef stays tender and juicy, avoid overcooking it when warming in the beef au jus. Keep the heat low and warm it just until heated through. This will help maintain the meat's natural moisture and flavor.

How To Reheat Leftovers
Preheat your oven to 300°F (150°C). Wrap each beef on weck sandwich in aluminum foil to keep the bread from drying out. Place the wrapped sandwiches on a baking sheet and heat for about 15-20 minutes, or until the roast beef is warmed through.
If you prefer using a microwave, place the roast beef slices in a microwave-safe dish and add a few tablespoons of beef au jus. Cover the dish with a microwave-safe lid or plastic wrap, leaving a small vent. Microwave on medium power for 1-2 minutes, checking and stirring halfway through to ensure even heating. Toast the kummelweck rolls separately in a toaster or under a broiler for a minute or two.
For a stovetop method, heat a skillet over medium heat. Add the roast beef slices along with a few tablespoons of beef au jus. Cover the skillet and let the roast beef steam for about 3-5 minutes, stirring occasionally, until heated through. Toast the kummelweck rolls in a separate pan or under a broiler.
If you have an air fryer, preheat it to 300°F (150°C). Wrap the beef on weck sandwiches in aluminum foil and place them in the air fryer basket. Heat for about 10-12 minutes, checking halfway through to ensure they are warming evenly.
