Directions
Step 1: Place the Roast in the Slow Cooker
Place your beef roast directly into the bottom of the slow cooker. No need to sear it first — the slow cooker will handle everything. For the juiciest results, choose a chuck roast with good marbling. The fat runs throughout the meat and slowly melts as it cooks, essentially basting the roast from the inside out and keeping it incredibly moist.
Step 2: Mix and Pour the Sauce
In a medium bowl, combine the cranberry sauce and dry onion soup mix. Stir until the two are fully blended into a smooth, flavorful sauce. Pour the mixture evenly over the beef roast, making sure the top and sides are well coated. Place the butter on top of the roast — it will melt down over the meat as it cooks, enriching the gravy and keeping the beef beautifully moist throughout the long cook time.
