This horseradish pot roast is pure comfort food with a flavorful twist. The beef cooks low and slow until fork-tender, soaking up a rich, savory sauce with just enough horseradish to add depth without being overwhelming.
Horseradish: I don’t love horseradish, but the flavor it gives this roast is incredible! Whether you love it or hate it, this recipe tastes amazing!
Well-balanced flavor: The sauce is rich and savory, thanks to the garlic, Worcestershire, and thyme, making every bite taste amazing.
Perfect with all the cozy sides: Serve it with mashed potatoes, buttered noodles, or roasted vegetables and 1-hour rolls to soak up every last bit of that delicious sauce.
Beef Options: While chuck roast works best, you can also use bottom round or eye of round.
Add Potatoes: For a heartier meal, toss in 1–2 lbs of baby potatoes (requires a 7–8 quart slow cooker).
Extra Veggies: Carrots, celery, or mushrooms can be added, stick to about 1 cup each (up to 3 cups total). If adding, pour in ¼–½ cup extra beef broth to keep the sauce flavorful.
Season to Taste: After whisking in the sour cream, taste the sauce and adjust with more salt and pepper if needed.
Swap the Liquid: Replace some or all of the beef broth with red wine or beer to change the flavor.
This pot roast recipe is easy to make and full of flavor, with just the right hint of horseradish that mellows as it cooks. For a little extra kick, stir 1–2 teaspoons of horseradish into the sour cream when finishing the sauce. Serve it over mashed potatoes or rice, or turn it into a cozy French Dip style sandwich
Sear: Pat the roast completely dry with paper towels and season all sides with salt and pepper. Heat a large skillet over medium-high heat. Sear the roast on all sides until a brown crust forms, about 3 minutes per side.
Add Onion: Place the roast in the bottom of a large slow cooker, then add the onion over the top.
Start the Sauce: Once the roast is removed from the skillet, reduce the heat to medium and add the beef broth. Use a wooden spoon to gently scrape up all the browned bits from the bottom of the skillet, then turn off the heat.
Combine: Add the tomato paste, horseradish, garlic, and Worcestershire, and stir until combined. Pour over the roast.
Slow Cook: Add the thyme to the slow cooker. Cover and cook on LOW for 9-10 hours, or on HIGH for 6-8 hours.
Add Slurry: In the final 45-60 minutes of cooking, skim off any fat, then whisk the cornstarch and cold water in a small bowl to make a slurry. Add it to the slow cooker.
Serve: Once the roast is tender and the sauce has thickened, discard the thyme. Remove the meat, cover with foil, and whisk some sauce into the sour cream until smooth, then stir it back into the slow cooker. Shred or slice the horseradish pot roast as desired and serve.
Dry Brine: After drying and seasoning the beef, refrigerate uncovered overnight (or up to 3 days). This enhances flavor and helps the beef sear beautifully.
Deglaze! Don’t skip the deglazing step after searing. The browned bits (fond) add an incredible caramelized flavor to your sauce.
