Try using a mix of horseradish and Dijon mustard for a tangier sauce.
Serve with pickles or sautéed onions for added texture and taste.

Storage

Store leftover beef and horseradish sauce separately in airtight containers in the refrigerator for up to 3 days. Reheat the beef gently in the microwave or on the stove with a splash of beef broth to keep it moist. Add the sauce after reheating to maintain its creamy texture.

FAQs

Can I use a different cut of beef?

Yes, a beef brisket or round roast can be used, but cooking times may vary slightly depending on the cut.

Is it necessary to strain the meat before serving?

Straining helps remove excess liquid for less soggy sandwiches, but you can skip this step if you prefer a juicier filling.
