Beef roast cooks low and slow in a flavor-packed liquid in your slow cooker until seriously tender. These Crock-Pot French Dip Sandwiches with Creamy Horseradish Spread are a delicious choice on even the busiest day.
Trim excess fat from the edges of the roast and place into the liquid in the slow cooker. Set slow cooker on LOW and cook for 7 to 9 hours, or to desired level of tenderness. Power off the slow cooker.
Use two forks to shred the beef to the desired consistency into the liquid in the slow cooker.
Combine the sour cream and creamed horseradish in a small bowl. Cover and refrigerate until ready to serve.
Preheat oven to 400 degrees F.
Split open the hoagies rolls but do not separate them. Spread them with the softened butter and place them on a baking sheet. Transfer the baking sheet to the oven and bake for 3 to 5 minutes or until lightly golden and toasted.
Spread the toasted rolls with some of the creamy horseradish spread and use tongs to fill them with the shredded beef. Spoon some of the au jus into small bowls and serve with the sandwiches for dipping.
