Grandma’s 4-Ingredient Onion Soup Pot Roast — The Most Tender Beef You’ll Ever Taste!

And when she says this is “the most tender beef she’s ever tasted,” you listen.

This 4-ingredient slow cooker pot roast is the ultimate Midwestern comfort classic: a chuck roast, onions, beef broth, and a packet of dry onion soup mix. That’s it. No searing. No fancy steps. Just set it and forget it—and come home to beef so tender it melts at the touch of a fork, bathed in a rich, savory gravy that tastes like it simmered for days.
