Ingredients and Their Role

For the Pot Roast

  • 2-pound chuck roast: The star of the dish! Chuck roast is well-marbled and ideal for slow cooking, breaking down into melt-in-your-mouth tenderness.
  • 2 cloves garlic: Adds deep, aromatic flavor to the gravy and roast.
  • 8 oz baby carrots: Bring a subtle sweetness and vibrant color to balance the savory beef.
  • 16 oz gold potatoes (halved or quartered if large): These creamy, buttery potatoes hold their shape beautifully when cooked and pair perfectly with the rich gravy.
  • 1/2 cup red wine: Elevates the flavor of the gravy, adding depth and richness. (Substitute with additional beef broth if preferred.)
  • 1 tablespoon herb and garlic seasoning: The perfect blend to season the roast and enhance the flavor of the entire dish.
  • 1 tablespoon olive oil + 1 tablespoon butter: Used for searing the roast, which locks in flavor and creates a caramelized crust.
  • 1/2 sweet yellow onion: Provides a touch of natural sweetness to the broth and gravy.
  • 3 cups beef broth: Acts as the base of the gravy, keeping the meat moist and flavorful.
  • 1/4 cup tapioca pearls: A unique thickener that creates a luscious, silky gravy without altering the taste.
  • 1/4 cup cornstarch (for slurry): Thickens the gravy to the perfect consistency.
  • 2 tablespoons tomato paste: Adds a slight tanginess and deep umami flavor to the gravy.

Instructions for Slow Cooker Pot Roast with Gravy

1. Season the Chuck Roast

Rub the herb and garlic seasoning evenly over the chuck roast. This step ensures the meat absorbs maximum flavor as it cooks.

2. Sear the Roast

In a large skillet or multi-cooker, heat olive oil and butter over medium-high heat. Once hot, place the roast into the skillet and sear each side for about 2-3 minutes or until a golden-brown crust forms.

Pro Tip: Don’t skip browning the meat! This step adds incredible flavor to the dish and enhances the final result.

3. Transfer to Slow Cooker

Place the seared roast into your slow cooker. Add the baby carrots, halved gold potatoes, and sliced sweet yellow onion around the roast.

4. Prepare the Gravy Base

In a medium bowl, whisk together:

  • 1/4 cup cornstarch slurry (cornstarch mixed with 1/4 cup cold water)
  • 3 cups beef broth
  • 1/2 cup red wine
  • 2 tablespoons tomato paste

Mix until smooth and fully combined. Stir in the tapioca pearls for an extra silky texture.

5. Pour and Cook

Pour the gravy mixture over the roast and vegetables. Cover and set the slow cooker to low for 8-10 hours.

Note: Cooking on high heat is not recommended, as low and slow ensures the chuck roast becomes fork-tender and flavorful.

6. Serve

Once done, carefully remove the roast, carrots, and potatoes. Shred the beef if desired. Serve the pot roast over mashed potatoes, ladled generously with the thick, savory gravy.

Pro Tips for Perfecting This Dish

  1. Sear the Meat: While optional, browning the roast ensures maximum flavor. Don’t skip it!
  2. Red Wine Substitution: If you prefer not to use wine, replace it with additional beef broth.
  3. Don’t Overcook the Vegetables: Add the potatoes and carrots later (around the 4-hour mark) if you like them firmer.
  4. Thickness Control: If the gravy is too thick, stir in a bit of warm broth to thin it out.

Serving Suggestions

  • Serve the pot roast over creamy mashed potatoes, which soak up the gravy perfectly.
