Ingredients
Beef chuck roast — 3.5 pounds, well-marbled for tenderness
Kosher salt — 1 teaspoon, to season the roast
Black pepper — 1 teaspoon, to season the roast
Olive oil — 2 tablespoons, for searing
Yellow onion — 1 large (about 2 cups), sliced thin for sweetness
Garlic — 4 cloves, minced for depth
Low-sodium beef broth — 2 cups, cooking liquid and gravy base
Worcestershire sauce — 2 tablespoons, savory tang
Dry red wine (optional) — 1/2 cup, added richness
Cornstarch — 3 tablespoons, thickens gravy
Cold water — 3 tablespoons, to make slurry
Russet potatoes — 3 pounds, peeled and cubed for mash
Unsalted butter — 4 tablespoons, for creamy potatoes
Milk (or half-and-half) — 1/2 cup, warmed for mash
Kosher salt (for potatoes) — 1 teaspoon, to taste
Thick-cut sandwich bread or Texas toast — 8 slices, toasted for serving
Fresh parsley (optional) — 2 tablespoons, chopped for garnish
Instructions
1. Pat the 3.5 lb chuck roast dry. Season all over with 1 tsp kosher salt and 1 tsp black pepper.
2. Heat 2 Tbsp olive oil in a large skillet over medium-high. Sear roast 3–4 minutes per side until deeply browned.
3. Add sliced onion and minced garlic to a 6‑quart slow cooker. Place seared roast on top.
4. Pour in 2 cups beef broth, 2 Tbsp Worcestershire, and (optional) 1/2 cup red wine.
5. Cover and cook on LOW for 8–9 hours (or HIGH 4–5) until the beef shreds easily with forks.
6. About 30 minutes before serving, transfer roast to a board and shred into large chunks; tent with foil.
7. Whisk 3 Tbsp cornstarch with 3 Tbsp cold water. Stir slurry into the slow cooker juices. Cover and cook on HIGH 10–15 minutes until thick and glossy. Season gravy to taste.
8. Make mashed potatoes: Boil 3 lb russets in salted water until tender (15–20 minutes). Drain well. Mash with 4 Tbsp butter and 1/2 cup warm milk; season with 1 tsp salt (or to taste).
9. Toast 8 slices thick-cut bread. For each serving, place toast on a plate, add a generous scoop of mashed potatoes, pile on shredded beef, and ladle hot gravy over the top.
10. Garnish with chopped parsley if using. Serve hot and enjoy that cozy, diner-style goodness.
Notes
Yield & portions: Makes about 8 hearty servings.
Beef swaps: Bottom round or brisket work, but chuck gives the most succulent shred.
Gravy tweak: For extra savoriness, add 1 teaspoon Dijon or a dash of soy sauce to the gravy.
Make-ahead: Cook the beef up to 3 days ahead; reheat in gravy with a splash of broth.
Gluten-friendly option: Serve over mashed potatoes or cauliflower mash and skip the toast; use gluten-free Worcestershire if needed.
Storage: Refrigerate leftovers up to 4 days or freeze (meat + gravy) up to 3 months.
Large family tip: Double the potatoes and toast for 10–12 plates without needing more meat.
