Horseradish Pot Roast Recipe
Introduction
This Horseradish Pot Roast is a flavorful twist on a classic comfort meal. Slow-cooked to tender perfection and infused with the zing of horseradish, it makes a satisfying main dish for any gathering or cozy dinner.

Ingredients
- 3-4 pound boneless beef chuck roast
- 1 ½ teaspoons salt
- ½ teaspoon ground black pepper
- 1 chopped yellow onion (about 1 ½ cups)
- 1 cup beef broth
- 3 tablespoons tomato paste
- ⅓ cup prepared horseradish (more or less to taste)
- 2 tablespoons minced garlic (about 6 cloves)
- 1 tablespoon Worcestershire sauce
- 3 sprigs fresh thyme (or 1 teaspoon dried thyme)
- 3 tablespoons cornstarch (to thicken)
- 3 tablespoons cold water (to thicken)
- ¼ cup sour cream
Instructions
- Step 1: Pat the beef chuck roast completely dry with paper towels and season all sides evenly with salt and ground black pepper.
- Step 2: Heat a large skillet over medium-high heat and sear the roast on all sides until a brown crust forms, about 3 minutes per side.
- Step 3: Place the seared roast in the bottom of a large slow cooker and top with the chopped yellow onion.
- Step 4: In the same skillet, reduce heat to medium and add the beef broth. Scrape the browned bits from the bottom with a wooden spoon, then turn off the heat. Stir in the tomato paste, prepared horseradish, minced garlic, and Worcestershire sauce, mixing until combined.
- Step 5: Pour this mixture over the roast in the slow cooker, then add the fresh thyme sprigs.
- Step 6: Cover and cook on LOW for 9-10 hours or on HIGH for 6-8 hours, until the roast is tender.
- Step 7: During the last 45-60 minutes of cooking, skim off any fat from the surface. In a small bowl, whisk together cornstarch and cold water to make a slurry, then stir it into the slow cooker to thicken the sauce.
- Step 8: When the roast is tender and the sauce has thickened, remove and discard the thyme sprigs. Transfer the meat to a plate and cover with foil to keep warm.
- Step 9: Whisk a small amount of the roast liquid into the sour cream until smooth, then stir this mixture back into the slow cooker.
- Step 10: Slice or shred the roast as desired, return it to the slow cooker, and serve warm with the horseradish sauce.
Tips & Variations
- Adjust the horseradish quantity based on how spicy you like the dish; start with less and add more to taste.
- For a thicker gravy, allow the slurry to cook a bit longer before adding the sour cream.
- Fresh thyme adds brightness, but dried thyme works well if fresh isn’t available—just use less.
- This roast pairs beautifully with mashed potatoes or roasted root vegetables.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove or in the microwave to preserve tenderness and prevent the sour cream from curdling.

FAQs
Can I make this pot roast in the oven instead of a slow cooker?
Yes, you can braise the roast in a covered oven-safe pot at 325°F (163°C) for about 3 to 4 hours until tender, using the same liquid ingredients.
Is prepared horseradish the same as fresh horseradish root?
Prepared horseradish is grated fresh horseradish root mixed with vinegar and salt, ready to use. Fresh horseradish root can be used but needs to be peeled, grated, and mixed with an acid like vinegar to mimic prepared horseradish.

Ingredients
Beef and Seasonings
- 3–4 pound boneless beef chuck roast
- 1 ½ teaspoons salt
- ½ teaspoon ground black pepper
Vegetables and Aromatics
- 1 chopped yellow onion (about 1 ½ cups)
- 2 tablespoons minced garlic (about 6 cloves)
- 3 sprigs fresh thyme (or 1 teaspoon dried thyme)
Liquids and Sauces
- 1 cup beef broth
- 3 tablespoons tomato paste
- ⅓ cup prepared horseradish (more or less to taste)
- 1 tablespoon Worcestershire sauce
- ¼ cup sour cream
Thickening Agent
- 3 tablespoons cornstarch
- 3 tablespoons cold water
Instructions
- Sear the Beef: Pat the beef chuck roast completely dry using paper towels. Season all sides evenly with 1 ½ teaspoons salt and ½ teaspoon ground black pepper. Heat a large skillet over medium-high heat and sear the roast on all sides until a rich brown crust forms, about 3 minutes per side. This step locks in flavor and adds depth to the final dish.
- Add to Slow Cooker: Transfer the seared roast to the bottom of a large slow cooker. Spread the chopped yellow onion evenly over the top of the roast.
- Deglaze the Skillet and Prepare Sauce: With the heat reduced to medium, pour 1 cup of beef broth into the skillet used for searing. Use a wooden spoon to scrape up all the flavorful browned bits stuck to the bottom. Turn off the heat. Stir in 3 tablespoons tomato paste, ⅓ cup prepared horseradish, 2 tablespoons minced garlic, and 1 tablespoon Worcestershire sauce until fully combined.
- Pour Sauce Over Roast: Pour this horseradish-tomato mixture evenly over the roast and onions in the slow cooker. Add 3 sprigs of fresh thyme on top for aromatic flavor.
- Slow Cook: Cover the slow cooker and cook on LOW for 9-10 hours or on HIGH for 6-8 hours, until the roast is fork-tender and infused with flavors.
- Thicken the Sauce: In the last 45-60 minutes of cooking, skim off any fat from the surface of the slow cooker liquid. Whisk together 3 tablespoons cornstarch and 3 tablespoons cold water in a small bowl to create a slurry. Stir this slurry into the slow cooker to thicken the sauce.
- Remove Roast and Discard Thyme: Once the roast is tender and sauce thickened, remove the thyme sprigs and take the meat out to a plate. Cover it with aluminum foil to keep warm.
- Add Sour Cream to Sauce: In a small bowl, whisk some of the hot roast liquid into ¼ cup sour cream until it becomes smooth and slightly warmed. Stir this mixture back into the slow cooker to add richness and a creamy tang to the sauce.
- Serve: Shred or slice the pot roast as desired, return the meat to the slow cooker to coat in sauce, then serve hot with your favorite sides.
Notes
- For best results, pat the beef roast dry before searing to ensure a good crust forms.
- The prepared horseradish level can be adjusted based on your preference for heat and pungency.
- If you don’t have fresh thyme, dried thyme can be used but reduce quantity accordingly.
- Skimming fat before thickening ensures a cleaner sauce without excess grease.
- The sour cream added at the end tempers the sharpness of horseradish and adds a creamy finish; add gradually and taste.
- This recipe is ideal for a slow cooker but can be adapted for oven braising at 300°F for 3-4 hours covered.
