Ingredients

Scale
  • 3–4 pounds beef chuck roast (well-marbled for tenderness and rich flavor)
  • 2 tablespoons olive oil (for searing the beef)
  • 1 large yellow onion, sliced
  • 3 medium carrots, peeled and cut into chunks
  • 2 celery stalks, chopped
  • 4 cloves garlic, minced
  • 2 cups beef broth (480 ml)
  • 1 cup Guinness stout (240 ml) – optional, can substitute with more beef broth
  • 2 tablespoons tomato paste
  • 1 teaspoon dried thyme
  • 1 teaspoon dried rosemary
  • 2 bay leaves
  • Salt and freshly ground black pepper, to taste
  • About 2 pounds potatoes (Yukon Gold or Russet) for mashed potatoes
  • 4 tablespoons butter, softened
  • 1/2 cup milk or cream, warmed (120 ml) – use dairy-free alternative if needed
  • Fresh parsley, chopped (for garnish)

Instructions

  1. Prep your ingredients (10 minutes): Slice the onion, peel and chop carrots and celery, mince garlic, and peel potatoes for mashing. Trim any excess fat from the beef chuck roast.
  2. Sear the beef (8-10 minutes): Heat olive oil in a skillet over medium-high heat. Season the beef generously with salt and pepper, then brown on all sides until a deep crust forms, about 4 minutes per side.
  3. Layer the slow cooker (5 minutes): Place onions, carrots, celery, and garlic in the bottom of the slow cooker. Lay the seared beef on top of the vegetables.
  4. Make the sauce (3 minutes): Whisk together beef broth, Guinness (if using), and tomato paste until smooth. Pour over the beef and vegetables. Sprinkle thyme, rosemary, and add bay leaves. Stir gently to combine.
  5. Cook low and slow (7-8 hours): Cover and set the slow cooker to low. Cook until beef is tender and falls apart easily.
  6. Prepare the mashed potatoes (while beef cooks, about 30-40 minutes): Cut potatoes into chunks, cover with cold salted water, and boil until tender, about 15-20 minutes. Drain well.
  7. Mash potatoes (10 minutes): Return potatoes to pot or bowl. Add softened butter and warm milk or cream. Mash until smooth and creamy. Season with salt and pepper to taste.
  8. Finish the beef (5 minutes): Remove beef from slow cooker and let rest. Remove bay leaves from sauce. If sauce is too thin, simmer in a skillet until thickened to desired consistency.
  9. Slice and serve: Slice beef against the grain into thick pieces. Plate with mashed potatoes and spoon over gravy. Garnish with chopped fresh parsley.

Notes

Searing the beef is essential for deep flavor. Cook on low heat for tender, fall-apart beef. Add vegetables halfway through cooking if you prefer them less soft. Check tenderness at 6.5 hours if your slow cooker runs hot. For thicker gravy, reduce sauce on stovetop. Use gluten-free broth and avoid flour thickeners for gluten-free version. Substitute mashed potatoes with mashed cauliflower for lower carbs.
