This American classic is a staple for busy households. By layering hearty root vegetables like carrots and potatoes under the roast, they soak up all the juices from the beef and the rich onion broth, resulting in a complete one-pot meal that requires very little cleanup.

Ingredients

• Beef: 3 lbs (1.4 kg) chuck roast, trimmed
• Seasoning & Soup Mix: 1 packet (about 1 oz/28 g) onion soup mix, 1 tsp black pepper, 1 tsp dried thyme (optional)
• Vegetables: 1 lb (450 g) carrots (peeled and cut into 2-inch pieces), 1 lb (450 g) baby potatoes (halved), 3 celery stalks (cut into 2-inch pieces), 1 large onion (cut into wedges)
• Liquids: 2 cups (480 ml) beef broth, 2 tbsp tomato paste, 2 tbsp Worcestershire sauce
• For Gravy (optional): 2 tbsp cornstarch, 2 tbsp cold water

Instructions

Step 1

Pat the beef chuck roast dry with paper towels. Season with black pepper (and thyme, if using).

Step 2

Place carrots, potatoes, celery, and onion in the bottom of the slow cooker.

Step 3

Lay the roast on top of the vegetables.

Step 4

In a bowl, whisk together beef broth, onion soup mix, tomato paste, and Worcestershire sauce. Pour over the roast and vegetables.

Step 5

Cover and cook on LOW for 8 hours (or HIGH for 5-6 hours), until the roast is fork-tender and vegetables are cooked through.

Step 6

Remove the roast and vegetables to a serving platter.

Step 7

Optional: To thicken the sauce, mix cornstarch with cold water, then stir into the slow cooker. Cover and cook on HIGH for 5-10 minutes until thickened.

Step 8

Slice or shred the roast, serve with vegetables and spoon gravy over the top.

Zusatztipps für die Zubereitung

For extra flavor, sear the roast in a hot skillet with a little oil before adding it to the slow cooker. This step helps lock in juices and creates a richer color for the final gravy. Ensure you use a slow cooker that is at least 6-quart in size to allow for even heat distribution.

Varianten und Anpassungen

You can easily customize the vegetable mix by substituting parsnips or turnips for some of the potatoes. For those with dietary restrictions, ensure you use a gluten-free onion soup mix and a certified gluten-free Worcestershire sauce, as some brands may contain hidden gluten or soy.

Serviervorschläge

This pot roast is delicious when served with crusty bread or extra mashed potatoes to soak up the savory gravy. To elevate the meal, pair it with a robust red wine, such as a Cabernet Sauvignon, which complements the deep beefy flavors and onion-infused sauce.
