Recipe Questions & Answers

How should I serve the cooked beef?

Shred the beef in the cooker and serve hot alongside mashed potatoes, rice, or fresh rolls for a hearty meal.

Is it possible to use a different seasoning mix?

You can substitute the au jus mix with onion soup mix, but the flavor profile will change accordingly.
