Step-by-Step Instructions
1. Sear the Beef (Don’t Skip This)

Pat beef dry.
-
Season all sides with salt, pepper, garlic powder, onion powder, paprika, and herbs.
-
Heat olive oil in a skillet over medium-high.

Beef broth
-
Gravy or soup mix
-
Worcestershire

Soy sauce

Tomato paste

Sugar
Pour evenly over the beef.
4. Slow Cook to Perfection

5. Shred & Soak
-
Remove beef and shred using two forks.
-
Return shredded beef to the slow cooker.
-
Stir well so every strand is coated in gravy.

Cook an additional 20–30 minutes on LOW to soak up flavor.
