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 dry with paper towels and season all sides with salt and pepper.
Step 2: Heat a large skillet over medium-high heat. 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. Top with the chopped yellow onion.
Step 4: In the skillet used for searing, reduce heat to medium and add beef broth. Scrape any browned bits from the pan with a wooden spoon, then turn off the heat.
Step 5: Stir in tomato paste, prepared horseradish, minced garlic, and Worcestershire sauce until combined. Pour this mixture over the roast in the slow cooker.

Step 6: Add fresh thyme sprigs to the slow cooker. Cover and cook on LOW for 9-10 hours or on HIGH for 6-8 hours until the roast is tender.
Step 7: About 45-60 minutes before the end of cooking, skim off any fat from the surface.
Step 8: Whisk together cornstarch and cold water to form a slurry, then stir it into the slow cooker to thicken the sauce.

Step 9: When the roast is fully tender and the sauce is thickened, remove and discard the thyme sprigs.
Step 10: Transfer the roast to a plate and cover with foil to keep warm. Whisk a little of the cooking liquid with sour cream until smooth, then stir it back into the slow cooker.
Step 11: Slice or shred the roast as desired, return it to the slow cooker, and serve with the horseradish sauce.

Tips & Variations

Adjust the amount of horseradish to suit your taste—start with less if you prefer a milder flavor.
For even more depth, add a splash of red wine to the broth mixture before cooking.
Serve over mashed potatoes or egg noodles to soak up the flavorful sauce.

Storage

Store leftover pot roast and sauce in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop or in the microwave, stirring occasionally to maintain a smooth sauce. The meat can also be frozen for up to 3 months; thaw overnight in the refrigerator before reheating.

How to Serve

A close-up top view of a pot filled with cooked beef in a rich brown sauce, showing two main layers: the beef itself and the sauce. The beef covers most of the pot, with one part whole and browned with visible texture and slight char, and another part shredded into fibrous pieces. The sauce is thick, glossy, and brown with some orange oil sheen, surrounding the beef and pooling at the edges. Small green herb leaves are scattered on top for garnish. A long metal fork with two prongs is stuck into the shredded beef, pulling it apart. The background inside the pot is dark, highlighting the colors and textures of the beef and sauce.

FAQs

Can I use dried thyme instead of fresh?

Yes, 1 teaspoon of dried thyme works well as a substitute for 3 sprigs of fresh thyme. Add it with the other ingredients before cooking.

How can I tell when the pot roast is done?

The pot roast is done when it is fork-tender and easily shredded or sliced. Cooking times may vary, so check for tenderness near the end of the slow cooking period.
