Whip up some delicious horseradish beef sandwiches with just a few ingredients and the recipe to make your very own homemade creamy horseradish sauce. If you’re looking to please your family (or a crowd), these gourmet sandwiches are the perfect things to make.

There’s so much you can do with a chuck roast. Use it to make my Slow Cooker Coca Cola Pot Roast or Pot Roast with Blue Cheese Gravy.

Why this horseradish roast beef sandwich recipe works

For starters, these roast beef sandwiches are made from a nice sized chuck roast smothered in beef broth. The seasonings come from using Lipton onion soup mix, whole garlic cloves, black pepper, and Worcestershire sauce – that’s it! The iconic topping comes from combining sour cream with prepared horseradish, more Worcestershire sauce, milk, and kosher salt.

There’s so much you can do with these sandwiches. You’ll quickly see why they are a personal preference when I’m looking for a quick and easy main course meal to serve my friends and family. The prep time is short and the cooking time is nice and long to yield a tender, pull-apart roast beef.

Recipe Ingredients

• Chuck Roast: You’ll want to grab a chuck that’s on the larger side, about 3-4 pounds. Look for one with good marbling, which only enhances the flavors. We also use a chuck roast in my Slow Cooker Italian Beef Sandwiches.
• Lipton Onion Soup Mix: The primary seasonings in this mix are dehydrated onions, salt, onion powder, sugar, and soy sauce – all of which help take the guesswork out of how to season the meat. A touch of salt and pepper is also added for more flavor.
• Garlic: Whole, peeled garlic cloves will add so much flavor during the cooking process.
• Beef Broth: The roast beef will simmer in the broth and aid in adding both flavor and texture.
• Homemade Creamy Sauce Ingredients: Sour cream, horseradish cream, Worcestershire sauce, milk, and salt are combined to make a great sandwich.
• Buns: These are the go-to for making the sandwiches but you can use any bread of your choice.

Step-by-Step Directions

Step One – Add the chuck roast to the slow cooker.

Step Two – Sprinkle over the onion soup mix and add the garlic cloves on top of the roast.

Step Three – Pour over the beef broth and Worcestershire sauce. Cover and cook on LOW for 9 hours.

Step Four – While the roast is cooking, make the horseradish sauce by adding a simple combination of horseradish ingredients in a small bowl and mixing with a spoon. Refrigerate until ready to serve.

Step Five – When the cooking time is up, shred the meat with 2 forks and discard any fat. You can do this right in the slow cooker or on a plate.

Step Six – Assemble a beef sandwich by draining a nice helping of meat, placing it on a bun, and topping it with a generous spread of creamy horseradish sauce.

What to serve with this:

• These beef sandwiches can be served as mentioned above with just the prepared horseradish cream sauce. To capture the true flavors of the creamy horseradish sauce, put some on the bottom half and top half of the bun. Add a little crispiness to the buns by brushing them with butter and toasting them.
• You can also add additional toppings such as caramelized onions, red onions, jalapeno peppers, mayonnaise, lettuce, arugula, and a slice of provolone cheese.
• As for sides, you can’t go wrong with serving potato chips, homemade potato fries, or a fresh salad like potato salad or pasta salad.
