Ingredients You’ll Need

Step-by-Step Instructions
Step 1: Prepare Your Slow Cooker
Start by layering the sliced onions at the bottom of your slow cooker. This creates a flavorful bed for the roast to sit on while also infusing the meat with delicious onion flavor.
Step 2: Season the Roast
Place the beef chuck roast on top of the onions. Then, sprinkle the French onion soup mix evenly over the roast, ensuring it’s well coated.
Step 3: Add the Broth
Pour 1 cup of beef broth around the roast, making sure not to wash off the seasonings on top. If you’re using Worcestershire sauce or garlic, add them at this stage for extra depth of flavor.
Step 4: Cook Low and Slow
Cover your slow cooker with its lid and set it to low for 6-8 hours or high for 4-6 hours. The low-and-slow method results in the most tender, fall-apart meat.
Step 5: Shred and Serve
Once the roast is fully cooked, use two forks to shred the beef directly in the slow cooker. Mix it with the caramelized onions and juices for an ultra-flavorful dish. Serve warm with mashed potatoes, crusty bread, or roasted vegetables.
Tips for the Best French Onion Pot Roast
- Sear the meat first – For added flavor, sear the beef in a hot pan before adding it to the slow cooker.
- Use a good-quality beef broth – This makes a huge difference in the overall taste.
- Let the meat rest – After cooking, let it sit for 10 minutes before shredding to keep it juicy.
