Ingredients

  • 3 to 4 pounds chuck roast
  • 2 tablespoons olive oil
  • 1 teaspoon kosher salt
  • 1 teaspoon freshly ground black pepper
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon dried thyme
  • 1 teaspoon dried rosemary
  • 1 tablespoon Worcestershire sauce
  • 3 cups low-sodium beef broth
  • 1 tablespoon tomato paste
  • 1 medium yellow onion, thinly sliced
  • 1½ pounds baby Yukon Gold potatoes
  • 4 large carrots, peeled and cut into large chunks
  • 3 garlic cloves, minced
  • 2 tablespoons cornstarch
  • 2 tablespoons cold water
  • 2 tablespoons chopped fresh parsley for garnish

Step-by-Step Instructions

Step 1: Prepare the Roast

Begin by patting the chuck roast completely dry with paper towels. Drying the meat helps it brown properly during searing. Sprinkle the roast evenly with kosher salt, black pepper, garlic powder, onion powder, dried thyme, and rosemary, coating both sides thoroughly.

Step 2: Sear the Beef

Heat the olive oil in a large skillet over medium-high heat. Once the oil is hot, carefully place the seasoned roast into the pan. Sear each side for approximately 2 to 3 minutes until a rich golden-brown crust develops. This extra step adds tremendous depth of flavor to the finished dish.

Step 3: Prepare the Slow Cooker

Arrange the sliced onions across the bottom of the slow cooker. Add the baby potatoes, carrot chunks, and minced garlic around the onions to create a flavorful vegetable base.

Step 4: Add the Roast

Place the browned chuck roast directly on top of the vegetables.

Step 5: Make the Cooking Liquid

In a mixing bowl, combine the beef broth, Worcestershire sauce, and tomato paste. Whisk until the tomato paste is fully incorporated and the mixture is smooth.

Pour this flavorful broth around the roast rather than directly over the top so the seasoning remains intact.

Step 6: Slow Cook

Cover the slow cooker with its lid.

Cook using one of the following settings:

  • Low: 8 to 9 hours for the most tender results.
  • High: 5 to 6 hours if you’re short on time.

The roast is ready when it easily pulls apart with a fork.

Step 7: Remove the Meat and Vegetables

Carefully transfer the beef, potatoes, carrots, and onions to a serving platter. Cover loosely with foil to keep everything warm while preparing the gravy.

Step 8: Prepare the Gravy

Whisk together the cornstarch and cold water until completely smooth.

Pour the slurry into the cooking liquid remaining in the slow cooker and stir well.

Turn the cooker to HIGH and cook for another 10 to 15 minutes, stirring occasionally, until the gravy thickens into a smooth, rich sauce.

Step 9: Serve

Slice the roast against the grain or shred it into large pieces.

Arrange it alongside the potatoes and carrots, generously spoon the homemade gravy over everything, and finish with freshly chopped parsley for a burst of color and freshness.

Serve immediately while hot.


Helpful Tips

  • Chuck roast is the ideal cut because its marbling melts during slow cooking, creating juicy, tender meat.
  • Searing the roast before slow cooking isn’t required but significantly enhances flavor.
  • Leave baby potatoes whole if they’re small, or halve larger ones for even cooking.
  • Avoid opening the slow cooker frequently, as this releases heat and extends cooking time.
  • If you enjoy thicker gravy, add a little extra cornstarch slurry until you reach your preferred consistency.

Storage

Store leftovers in an airtight container in the refrigerator for up to 4 days.

For longer storage, freeze the roast, vegetables, and gravy together in freezer-safe containers for up to 3 months.

Reheat gently on the stovetop or in the microwave until thoroughly warmed.


Serving Suggestions

This hearty roast is delicious on its own, but it also pairs beautifully with:

  • Warm buttered dinner rolls
  • Homemade biscuits
  • Steamed green beans
  • Roasted Brussels sprouts
  • Garden salad
  • Creamy mashed cauliflower
  • Buttered peas
