Step‑by‑Step Instructions for Crock Pot French Onion Pot Roast
Step 1: Prepare the Onion Mixture
In a large bowl, combine thinly sliced onions, minced garlic, beefy onion soup mix, dried thyme, and dried rosemary. Toss gently to ensure even distribution. This aromatic blend will form the flavorful base for your Crock Pot French Onion Pot Roast. Set the mixture aside while you prepare the slow cooker.
Step 2: Set Up the Slow Cooker
Lightly coat the bottom of your slow cooker with cooking spray to prevent sticking. Spread half of the onion mixture evenly across the bottom, creating a fragrant layer. Pour one can of condensed French onion soup over the onions, allowing the flavors to begin mingling.
Step 3: Sear the Chuck Roast
Pat the chuck roast dry with paper towels and generously season it with salt and pepper on all sides. In a large skillet, heat vegetable oil over medium-high heat until shimmering. Carefully place the roast in the hot skillet and sear for about 5 minutes, turning to achieve a deep brown crust on all sides.
Step 4: Layer the Roast in the Cooker
Once the chuck roast is nicely browned, transfer it to the slow cooker, placing it on top of the onion mixture. Top the roast with the remaining onion mixture, ensuring an even spread. Pour the second can of condensed French onion soup over everything and add small pats of unsalted butter on top for added richness.
Step 5: Slow Cook the Roast
Cover the slow cooker with its lid and set it to cook on low heat for 6 to 8 hours. This low-and-slow method allows for tender meat and rich flavor development in your Crock Pot French Onion Pot Roast. Resist the temptation to lift the lid during cooking, as each peek releases steam and prolongs cooking time.
Step 6: Shred the Roast
After the cooking time is complete and the roast is fork-tender, carefully transfer it to a plate. Using two forks, shred the beef into bite-sized pieces. This step not only breaks apart the roast but also allows it to soak up the flavors from the gravy.
Step 7: Make the Gravy
Pour the cooking liquid from the slow cooker into a skillet over medium heat. Allow it to simmer gently, and if you’d like a thicker gravy, mix a cornstarch slurry and add it gradually until the desired consistency is reached. Return the shredded beef to the slow cooker and stir to mix with the gravy.
Step 8: Keep Warm Until Serving
Set your slow cooker to the ‘warm’ setting to keep the shredded beef and gravy hot until you’re ready to serve. Garnish the finished Crock Pot French Onion Pot Roast with freshly chopped parsley for a pop of color and an aromatic touch that will elevate the dish at your table.
