Slow Cooker Pot Roast

Servings: 6
Prep Time 25 minutes
Cook Time 8 hours
Total Time 8 hours 25 minutes

Ingredients

  • 1 1/2 Tbsp olive oil, divided
  • 1 (3 lb) chuck roast*
  • Salt and freshly ground black pepper
  • 1 medium yellow onion, peeled, halved and cut into thick slices
  • 5 garlic cloves, minced (1 1/2 Tbsp)
  • 1 1/4 cups cup beef broth
  • 2 tsp Worcestershire sauce
  • 1 Tbsp minced fresh thyme
  • 1 Tbsp minced fresh rosemary
  • 2.5 lbs small yukon gold potatoes, left whole
  • 5 medium carrots (about 1 lb), peeled and cut into 1-inch pieces*
  • 2 1/2 Tbsp cornstarch mixed with 3 Tbsp beef broth, optional, for thickening gravy
  • 2 Tbsp chopped fresh parsley

Instructions

  1. Heat 1 Tbsp olive oil in a large pot over medium-high heat. Dab roast dry with paper towels, season all over with salt and pepper.

  2. Sear roast in pot until browned on both sides, about 4 - 5 minutes per side. Transfer roast to slow cooker. 

  3. Add remaining 1/2 Tbsp olive oil to pot. Add onion and saute 2 minutes, add garlic and saute 30 seconds longer. Pour onion mixture over roast in slow cooker. 

  4. Return pot to heat, pour in beef broth, Worcestershire, thyme and rosemary and cook about 15 seconds, just long enough to scrape up browned bits from the bottom of the pot. Remove from heat.

  5. Layer potatoes and carrots over onion layer in slow cooker, pour beef broth evenly over top then season with salt and pepper.

  6. Cover slow cooker and cook on low heat until roast and vegetables are tender, about 8 - 9 hours.

  7. Remove roast and vegetables, shred roast (discard fat) and cut potatoes if desired.

  8. If you'd like to thicken the broth and make a gravy, pour broth from slow cooker through a fine mesh strainer into a small saucepan**. Heat over medium-high heat. Whisk cornstarch with 3 Tbsp beef broth then pour into saucepan. Bring to a simmer, stirring constantly, let simmer 30 - 60 seconds. 

  9. Plate roast and vegetables, pour gravy over the top and sprinkle with parsley.

Recipe Notes

*Thicker carrots will work better here. They won't get too soft.

**I like to measure first to to see if I have the correct amount so I know if it will thicken properly, there should be 2 cups liquid, if you need more just stir in a little more beef broth to reach the correct amount. I also like to skim the extra fat from the top of the liquid. If you don't care to measure first you can always thin with a little broth if needed or thicken with a little extra cornstarch/broth mixture.
