Ingredients

  • For the Pot Roast: 3 lbs (1.4 kg) beef chuck roast, 1 tbsp kosher salt, 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 achieve a thicker gravy, remove ½ cup of the cooking liquid from the slow cooker and whisk it with 1 tbsp cornstarch. Stir it back into the slow cooker and cook on high for an additional 10 minutes. For a richer depth of flavor, you can substitute ½ cup of the beef broth with red wine before cooking.

Varianten und Anpassungen

You can use either Yukon Gold or Russet potatoes for the mashed potatoes—Yukon Golds provide a creamier, buttery texture, while Russets yield a fluffier finish. To keep the dish gluten-free, ensure you select gluten-free Worcestershire sauce and beef broth. Feel free to garnish with fresh parsley for a pop of color and freshness.

Serviervorschläge

Directions

Phase 01

Season and Sear Beef: Pat chuck roast dry with paper towels and coat all sides evenly with kosher salt and black pepper.
