Generously season your chuck roast on all sides with sea salt and ground black pepper.
Set the roast at the bottom of your slow cooker. Place thick-sliced yellow onions on top of the roast.
Cook on high for 4 hours.
After 4 hours, once the roast has released its juices, slide the onions into the liquid. Pour two cans (21 oz) of cream of mushroom soup over the roast and carefully mix with the juices without disturbing the roast.
Cook for another 2 hours on high. Check the roast for tenderness; it should fall apart easily with a fork.
If needed, cook for an additional hour. Once done, switch the slow cooker to warm to hold the roast until ready to serve.

Expert Tips
Wait to Add the Soup: Adding the cream of mushroom soup later in the cooking process ensures the roast develops color and doesn’t get boiled.
Sear the Roast First: If you have time, sear the roast in a cast iron skillet to create a caramelized crust for extra flavor.
Low and Slow is Best: If you have extra time, consider cooking the roast on low for 8 hours for even more tender results.
Storing Leftovers: Store any leftover roast and gravy in an airtight container for up to 4 days in the fridge. The flavors intensify as it sits, making for even better leftovers!
Freezing: This roast freezes beautifully. Just shred the meat, mix with the gravy, and freeze in individual portions for quick meals later on.
