Add 2/3 of the vegetables to the bottom of the slow cooker (the potatoes, onions and carrots).
Add the roast on top of those veggies. I do not brown my roast in a skillet, but you can at this point if desired.
Add the remaining vegetables around the pot roast.
Whisk together soups and cornstarch in a medium bowl, pour over roast.
Place the lid on the slow cooker. Cover and cook on LOW for 9-10 hours. Do not open the lid during the cooking time. This can be done on high for 6 hours on high but I recommend low and slow.
When the cooking time is done, I like to degrease the top of the gravy before serving. I do this by taking paper towels and laying over the grease. Pull up quickly and just the grease will be on the paper towel.
Shred or slice the pot roast.
Add salt and pepper to the gravy to taste.
Serve the pot roast with the veggies and drizzle over the gravy. Enjoy!

Notes
Can I add red wine?If you desire to add red wine to this recipe, add a 1/2 cup. But also add 1 more tablespoon of cornstarch to the soup mixture.Can I sear my roast before adding it to the slow cooker?I chose not to brown my chuck roast before adding to the slow cooker for this recipe. This recipe has the caramelized onions in the French onion soup, which adds so much flavor. And I like easy for this recipe. You certainly can sear your roast in a skillet on the stove-top (in olive oil or canola oil) and follow the exact directions of this recipe. This is true for most slow cooker recipes; if you prefer to brown, do what makes you happy!Can I use something other than French onion soup?Yes, and I highly suggest you do if you have family members who don't love onions. Use one can of Campbell's Beef Consume, beef broth or an additional can of cream of mushroom. You can add a touch of onion powder or garlic powder to make up for the flavor of the French onion soup.Can I use Lipton Onion Soup Mix?Yes, use one packet of onion soup mix instead of the French onion soup. Add one cup of water as well.Why is my roast not tender?You most likely did not cook long enough, it's not because you overcooked it. Place the lid back on the slow cooker (and keep it on). And cook for an additional 2 hours or more.
