Ingredients

  • 3-4 pounds beef chuck roast
  • 4 medium potatoes, peeled and cubed
  • 3 large carrots, sliced
  • 1 large onion, diced
  • 4 cloves garlic, minced
  • 2 cups beef broth
  • 1 tablespoon fresh thyme or 1 teaspoon dried thyme
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 tablespoon Worcestershire sauce
  • 2 tablespoons cornstarch (optional, for thickening gravy)
  • 2 tablespoons water (optional, for thickening gravy)

How to Make Slow Cooker Beef Roast with Vegetables

  1. Start by seasoning the beef roast with salt and pepper on all sides.
  2. In a large skillet over medium-high heat, sear the roast for 3-4 minutes on each side until browned. This step adds depth of flavor but can be skipped if you’re short on time.
  3. Transfer the roast to the slow cooker and add the cubed potatoes, sliced carrots, diced onion, and minced garlic on top of the meat.
  4. Pour the beef broth and Worcestershire sauce over the vegetables and roast. Sprinkle the thyme evenly across the top.
  5. Cover and cook on low for 8-10 hours or on high for 4-6 hours, until the beef is tender and easily shreds with a fork.
  6. Once cooked, remove the roast and vegetables from the slow cooker, keeping them warm on a platter.
  7. For the gravy, strain the remaining liquid into a saucepan. If you’d like a thicker gravy, combine cornstarch and water in a small bowl to create a slurry, then whisk it into the strained liquid over medium heat until it thickens.
  8. Serve the tender beef roast with the mashed potatoes and top everything generously with the rich gravy.

Tips for the Best Results

  • Use a well-marbled cut of beef for maximum tenderness and flavor.
  • Searing the roast before slow cooking enhances the overall taste but isn’t mandatory.
  • Make sure to use a good-quality beef broth for a richer flavor.
  • Adjust seasoning to your taste; feel free to add more herbs or spices.

Easy Variations

  • Add other root vegetables like parsnips or turnips for extra flavor.
  • Swap beef for pork shoulder for a different twist on the classic roast.
  • For a creamy twist, mix sour cream or cream cheese into the mashed potatoes.

What to Serve With It

  • Freshly baked dinner rolls or crusty bread for soaking up the gravy.
  • A side salad for a refreshing contrast to the hearty roast.
  • Steamed green beans or sautéed Brussels sprouts for added color and crunch.

Storage and Reheating

Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, warm in the microwave or on the stovetop over low heat, adding a splash of beef broth to keep it moist.
