The Only 4 Ingredients You Need

You read that right—just four ingredients. No complicated sauces, no long shopping list.

1. Chuck Roast (3–4 pounds)
This cut is ideal for slow cooking because its marbled fat melts into the meat, keeping it moist and tender.

2. One Packet of Ranch Seasoning Mix
Adds a tangy, herb-filled layer of flavor.

3. One Packet of Au Jus Gravy Mix
Deepens the richness and creates a savory base.

4. A Stick of Butter (½ cup)
Melts into the roast, enhancing tenderness and giving the dish a luxurious texture.

(Optional but popular: A handful of pepperoncini peppers for extra tang and subtle heat.)
