  • 1 tsp black pepper
  • 2 tbsp olive oil
  • 1 large onion, sliced
  • 4 cloves garlic, minced
  • 4 large carrots, peeled and cut into 2-inch pieces
  • 3 celery stalks, cut into 2-inch pieces
  • 2 cups (480 ml) beef broth (gluten-free if needed)
  • 2 tbsp tomato paste
  • 1 tbsp Worcestershire sauce (gluten-free if needed)
  • 1 tsp dried thyme
  • 1 tsp dried rosemary
  • 2 bay leaves
  • For the Mashed Potatoes
  • 2 lbs (900 g) Yukon Gold or Russet potatoes, peeled and cut into chunks
  • 4 tbsp unsalted butter
  • ½ cup (120 ml) whole milk (plus more as needed)
  • 1 tsp salt
  • ½ tsp black pepper
  • Optional Garnish
  • Chopped fresh parsley

Instructions

1. Pat the beef chuck roast dry and season all sides with salt and pepper.
2. 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.
3. Add onion, garlic, carrots, and celery around the roast in the slow cooker.
4. In a bowl, whisk together beef broth, tomato paste, Worcestershire sauce, thyme, rosemary, and bay leaves. Pour over the roast and vegetables.
5. Cover and cook on low for 8 hours, or until the beef is fork-tender.
6. About 40 minutes before serving, prepare the mashed potatoes:
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.
7. Remove the roast from the slow cooker and let rest for 5 minutes. Discard bay leaves. Shred or slice the beef.
8. Serve pot roast and vegetables over a bed of mashed potatoes. Drizzle with pan juices and garnish with fresh parsley if desired.

Zusatztipps für die Zubereitung

To enhance the gravy's thickness, set aside half a cup of the cooking liquid near the end of cooking. Whisk it with a tablespoon of cornstarch and return to the slow cooker, then cook on high for an additional 10 minutes. This creates a luscious, velvety sauce that clings beautifully to the beef and vegetables.

Varianten und Anpassungen

For a richer flavor, substitute half a cup of beef broth with red wine. Yukon Gold potatoes provide particularly creamy and buttery mashed potatoes, but Russet potatoes are a suitable alternative. Adjust seasonings to your preference and experiment with adding fresh herbs like parsley for brightness.

Serviervorschläge

Serve your slow cooker pot roast plated over a generous scoop of mashed potatoes, spooning the savory pan juices over the top. Garnish with chopped fresh parsley for a burst of color and fresh flavor. Pair with a bold red wine, such as Cabernet Sauvignon, to complement the robust meat and herbaceous notes.
