  • 1 large onion sliced
  • 2–3 garlic cloves minced
  • 2 cups beef broth

  • 1 teaspoon salt adjust to taste
  • ½ teaspoon black pepper
  • For the Gravy:

  • 2 tablespoons water to make slurry

Instructions
 

  • Prepare the Beef:
  • Season beef with salt and pepper.
  • Place in slow cooker along with sliced onions, minced garlic, beef broth, Worcestershire sauce, and thyme.
  • Cook:
  • Cover and cook on low for 7–8 hours or high for 4–5 hours, until beef is tender and shreds easily.
  • Make the Gravy:
  • Remove beef from the slow cooker and set aside.
  • Mix cornstarch and water in a small bowl to form a slurry.
  • Whisk slurry into the hot cooking liquid and cook on high for 5–10 minutes, or until thickened.
  • Make Mashed Potatoes:
  • Boil chopped potatoes in salted water until fork-tender.
  • Drain, mash, and mix in butter, milk or cream, and salt to taste.
  • Assemble the Dish:
  • Plate a scoop of mashed potatoes.
  • Top with shredded beef and a generous ladle of gravy.
  • Serve hot and enjoy!

Notes

  • Beef Tip: Chuck roast is ideal for slow cooking thanks to its marbling—it becomes ultra-tender and flavorful.
  • Gravy Tip: Whisk the slurry well to prevent lumps and stir continuously while thickening.
  • Shortcut: Instant mashed potatoes can be used in a pinch, though homemade is best for texture and flavor.
  • Storage: Store leftovers in the fridge for up to 3 days, or freeze beef and gravy for up to 3 months.
