Ingredients 

• 3 pound beef roast – Chuck roast works perfectly, but any cut suited for slow cooking will do.

How to Make Slow Cooker Cranberry Roast Beef

1. Prepare the roast – Place the beef roast in the bottom of your slow cooker.

2. Mix the sauce – In a bowl, stir together the cranberry sauce and onion soup mix.

3. Add to the slow cooker – Pour the sauce over the roast, then top with butter.

4. Add cranberries – Sprinkle fresh or frozen cranberries around the roast.

5. Cook – Cover and cook on low 6 hours or high 4 hours, until the beef is fork-tender.

6. Shred & serve – Shred beef with two forks, stir to coat in sauce, and garnish with parsley.

Substitutions

• Beef Roast – Chuck roast, rump roast, or brisket all work.

• Cranberry Sauce – Whole berry gives extra texture, jellied for smoother sauce. Homemade cranberry sauce also works beautifully.

• Butter – Can swap for olive oil if you prefer.

• Fresh Cranberries – Optional, but can be swapped for dried cranberries in a pinch (just add at the end).

Variations

• Cranberry Orange Roast – Add a splash of orange juice or zest.

Tips & Tricks

• Thicken the sauce – Make a cornstarch slurry (1 Tbsp cornstarch + 1 Tbsp water) and stir into the slow cooker at the end if you prefer a thicker gravy.

• Don’t overcook – Check at the 4-hour mark on high or 6 on low. Once fork-tender, it’s ready.

• Shred in the pot – Shredding directly in the sauce coats every bite.

• Serve with sides – Mashed potatoes, rice, or even stuffing soak up that amazing sauce.
