Sear the chuck roast then place in a slow cooker. Arrange the potatoes, carrots, onion, and garlic on top of the roast. Stir in the salt, Worcestershire sauce, pepper, thyme, and broth.
Cover and cook on low for 8-10 hours. Pot roast is done when it’s fork tender and shreds easily.
For a thick gravy, stir in a cornstarch slurry during the last hour of cooking. Simply whisk together 1 tablespoon of cornstarch with 1 tablespoon of water until smooth.
Notes
Store pot roast in an airtight container in the fridge for up to 5 days or freezer for up to 3 months. Let thaw in the fridge before reheating. Reheat in a saucepan or in the microwave until warmed through.
