Introduction

Slow Cooker Horseradish Beef Sandwiches are rich, tender, and packed with bold flavors. This easy recipe uses a slow cooker to transform a beef chuck roast into juicy, flavorful shredded beef perfectly complemented by a tangy horseradish sauce. It’s a delicious meal you can set and forget.

The image shows a slow cooker filled with shredded, cooked beef mixed with broth or cooking liquid, creating a shiny dark brown layer covering the entire inside surface. The beef pieces have visible stringy textures, some chunks appearing tender and moist. The slow cooker is white with a light green handle. Next to it on a white marbled surface are a white bowl with a creamy white sauce and spoon, a white basket with golden brown sandwich buns on a white napkin, metal tongs with white handles resting on a red and white checkered cloth, and salt and pepper shakers with a weathered look.

Ingredients

3-4 lbs. beef chuck roast
1 oz. Lipton onion soup mix
6 garlic cloves (peeled and left whole)
3 Tbsp. Worcestershire sauce
½ tsp. black pepper
15 oz. can beef broth
1 cup sour cream
1 Tbsp. milk (or buttermilk)
2 Tbsp. cream horseradish
½ tsp. salt
1 tsp. Worcestershire sauce

Instructions

Step 1: Add the chuck roast to the slow cooker.
Step 2: Sprinkle the onion soup mix evenly over the roast.
Step 3: Place the peeled garlic cloves on top of the roast.
Step 4: Pour the beef broth and Worcestershire sauce over the roast and season with black pepper.
Step 5: Cover and cook on LOW for 9 hours until the beef is tender and easy to shred.
Step 6: While the roast cooks, prepare the horseradish sauce by mixing sour cream, milk, cream horseradish, salt, and Worcestershire sauce in a small bowl. Refrigerate until ready to serve.
Step 7: When done, shred the beef using two forks, discarding any fat. You can shred the meat right in the slow cooker or transfer it to a plate.
Step 8: Toast sandwich buns if you like. Strain the beef to remove excess liquid, then pile the shredded meat onto the buns.
Step 9: Spoon the horseradish sauce over the beef, assemble the sandwiches, and serve immediately.

Tips & Variations

For extra flavor, add a splash of red wine or a few sprigs of fresh rosemary to the slow cooker.
Use marble rye or crusty rolls for a heartier sandwich experience.
Adjust the horseradish amount depending on how spicy you like your sandwiches.
Leftover shredded beef is great for tacos or topped on baked potatoes.

Storage

Store any leftover beef and horseradish sauce separately in airtight containers in the refrigerator for up to 3 days. Reheat the beef gently in a skillet or microwave, then add fresh horseradish sauce before serving to keep it creamy and bright.

How to Serve

A sandwich on a soft, golden-brown bun, placed on a white plate. The sandwich has two layers: the bottom layer is a thick, pulled dark brown shredded meat, and the top layer is a creamy white sauce sitting on the meat, just under the top bun. The bun is smooth and slightly shiny with some wrinkles on the top. The background shows a white marbled surface with a red and white checked cloth nearby. Photo taken with an iphone --ar 4:5 --v 7
