Instructions

Season & Sear Roast:
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 minutes per side). Transfer to the slow cooker.
Add Vegetables:
Add onion, garlic, carrots, and celery around the roast in the slow cooker.
Prepare Cooking Liquid:
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.
Rest & 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 Guide

What cut of beef is best for this dish?

Beef chuck roast is ideal due to its marbling and connective tissue, which slow cooking transforms into tender, flavorful meat.

Can I prepare the mashed potatoes ahead of time?

Yes, mashed potatoes can be made in advance and gently reheated with a splash of milk or butter to restore creaminess.

How can I thicken the cooking juices into a gravy?

Remove some cooking liquid, whisk with cornstarch, then stir back into the pot and cook on high for 10 minutes until thickened.

Is it possible to substitute any ingredients for dietary needs?

Using gluten-free beef broth and Worcestershire sauce keeps this dish gluten-free, and dairy-free alternatives for butter and milk can be used in mashed potatoes.

What wine pairs well with this slow-cooked beef dish?

A bold red wine such as Cabernet Sauvignon complements the rich flavors and enhances the dining experience.
