Instructions

Season and Sear the Beef:
Pat the beef chuck roast dry and season all sides with salt and pepper. In a large skillet, heat olive oil over medium-high heat. Sear the roast on all sides until browned (about 3–4 minutes per side). Transfer to the slow cooker.
Add Vegetables and Liquid:
Add sliced onion, garlic, carrots, and celery around the roast in the slow cooker. In a bowl, whisk together beef broth, tomato paste, Worcestershire sauce, thyme, rosemary, and bay leaves. Pour over the roast and vegetables.
Slow Cook:
Cover and cook on low for 8 hours, or until the beef is fork-tender.
Make Mashed Potatoes:
About 40 minutes before serving, place potatoes in a large pot and cover with cold water. Add 1 tsp salt. Bring to a boil, reduce heat, and simmer until potatoes are very tender (15–20 minutes). Drain well and return potatoes to the pot. Add butter and milk; mash until smooth and creamy. Season with salt and pepper to taste. Add more milk if needed for desired consistency.
Finish and Serve:
Remove the roast from the slow cooker and let rest for 5 minutes. Discard bay leaves. Shred or slice the beef. Serve pot roast and vegetables over a bed of mashed potatoes. Drizzle with pan juices and garnish with fresh parsley if desired.

Recipe Questions & Answers

How do I achieve tender beef in this dish?

Slow cooking the beef chuck roast at a low temperature for 8 hours breaks down connective tissues, resulting in tender, flavorful meat.

Can I use different potatoes for the mashed side?

Yes, Yukon Gold or Russet potatoes work well. Yukon Gold yields creamier mashed potatoes, while Russets offer a fluffier texture.

How can I thicken the gravy from the cooking liquids?

Remove some cooking liquid, whisk it with cornstarch, then stir back into the slow cooker and cook on high for 10 minutes to thicken.

Is it necessary to sear the roast before slow cooking?

Searing the roast adds depth of flavor and helps lock in juices, but you can skip this step for convenience.

What herbs enhance the flavor of the roast?

Dried thyme, rosemary, and bay leaves infuse the roast with aromatic, earthy notes during slow cooking.

Can I substitute red wine for broth?

Yes, replacing half the broth with red wine like Cabernet Sauvignon adds richness and complexity to the dish.
