Ingredients
  

For the roast
  • 2 lb chuck roast Trim excess fat if desired.
  • 2 cups red or yellow onion, thinly sliced
  • 3 cloves garlic, minced
  • 1 tbsp white wine vinegar
  • 1 tbsp Worcestershire sauce
  • 1/4 cup tomato sauce
  • 1 cup beef broth Use low-sodium if preferred.
  • 1 tsp salt
  • 1 tsp black pepper
  • 1/2 tsp fresh thyme, chopped Or 1/4 tsp dried.
  • 2 tsp fresh parsley, chopped For garnish.
  • 1–2 tbsp all-purpose flour or cornstarch For thickening.

Method
 

Preparation
  1. Whisk together the tomato sauce, beef broth, minced garlic, chopped thyme, Worcestershire sauce, and white wine vinegar in a small bowl. Set aside.
  2. Trim any excess fat from the chuck roast and season all sides with salt and black pepper. (Optional: sear in a hot skillet for 1–2 minutes per side for extra flavor.)
  3. Place half of the sliced onions at the bottom of the slow cooker. Pour half of the prepared sauce over the onions.
  4. Place the seasoned roast on top of the onion layer. Scatter the remaining onions over the roast, then pour the rest of the sauce evenly on top.
Cooking
  1. Cover and cook on HIGH for 4 hours or LOW for 7 hours until the roast is fork-tender.
  2. Remove the roast to a cutting board and tent with foil to rest. Skim fat from the surface of the cooking juices if necessary.
Gravy Preparation
  1. For each cup of leftover sauce in the slow cooker, whisk 1 tablespoon of flour or cornstarch with an equal amount of cold water to make a slurry. Stir the slurry into the sauce and heat on low until thickened. Adjust seasoning to taste.
Serving
  1. Slice or shred the roast, spoon gravy over the meat, and garnish with chopped parsley. Serve over mashed potatoes or your preferred side.
