Ingredients
  

  • 3 lb sirloin steak cut into 1-inch bite-sized pieces
  • 2 teaspoons kosher salt
  • 1 teaspoon black pepper
  • 2 tablespoons vegetable oil
  • 1 small sweet onion thinly sliced
  • 3 cloves garlic thinly sliced
  • 1 cup unsalted beef stock
  • 1 oz au jus gravy mix 1 packet
  • 4 tablespoons unsalted butter thinly sliced
  • fresh parsley chopped, for garnish (optional)

Equipment

  • large bowl
  • skillet
  • Crockpot or slow cooker
  • Tongs

Method
 

  1. Season the steak cubes generously with salt and pepper in a large bowl, tossing to coat evenly.
  2. Heat 1 tablespoon of vegetable oil in a skillet over medium-high heat until shimmering. Sear the steak in batches for 2-3 minutes, browning on all sides without overcrowding the pan. Transfer seared steak to the crockpot.
  3. Add the sliced onion and garlic to the crockpot, gently tossing with the steak to distribute evenly.
  4. Pour the beef stock over the meat, then sprinkle the au jus gravy mix across the top.
  5. Arrange the butter slices over the surface of the meat and liquid.
  6. Cover and cook on High for 3-4 hours or Low for 6-8 hours, stirring occasionally if possible.
  7. Test a piece of steak for tenderness at the minimum cooking time. If not fork-tender, continue cooking in 30-minute increments until desired tenderness is reached.
  8. Garnish with fresh chopped parsley if desired and serve warm over mashed potatoes or egg noodles.

Notes

Searing is recommended for deeper flavor but can be skipped for a true dump-and-go version. Round steak, stew meat, or chuck roast can be substituted for sirloin. For keto version, omit au jus mix and add extra butter and fresh herbs. Add seared mushrooms just before serving for extra depth.
