Salt
  • 0.25 tsp salt to taste
Black pepper
  • 0.25 tsp black pepper to taste
Garlic powder
  • 0.5 tsp garlic powder to taste
Olive oil
  • 2 tbsp olive oil
Butter
  • 6 tbsp butter, cubed
Garlic
  • 6 cloves garlic, minced
Dried Italian seasoning
  • 1 tsp dried Italian seasoning
Onion powder
  • 1 tsp onion powder
Beef broth
  • 0.5 cup beef broth
Worcestershire sauce
  • 1 tbsp Worcestershire sauce
Soy sauce
  • 1 tbsp soy sauce
Fresh parsley
  • 0.25 cup fresh parsley for garnish
Mashed potatoes or egg noodles
  • 6 servings mashed potatoes or egg noodles for serving

Equipment

  • 1 cast iron skillet
  • 1 Dutch oven

Method
 

Season and sear the beef
  1. Season the beef generously with salt, pepper, and garlic powder. Visual cue: the cubes look evenly coated with a light seasoning layer.
  2. Heat olive oil in a hot skillet over high heat and sear the beef in batches for 2-3 minutes per side until deeply browned, then transfer to a slow cooker. Visual cue: browned edges with caramelized color before it goes in.
Slow cook in garlic butter sauce
  1. Add cubed butter, minced garlic, dried Italian seasoning, onion powder, beef broth, Worcestershire sauce, and soy sauce to the slow cooker. Visual cue: you see melted butter and an amber, fragrant sauce starting to form around the beef.
  2. Cover and cook on LOW for 6-7 hours or HIGH for 3-4 hours until the beef is fork-tender. Visual cue: the beef easily breaks apart when poked with a fork.
Coat, taste, and serve
  1. Stir gently to coat the beef in the garlic butter sauce, then taste and adjust seasoning. Visual cue: the sauce clings to the meat with a glossy look.
  2. Serve over mashed potatoes or egg noodles and garnish with fresh parsley. Visual cue: parsley flecks on top and sauce pooling slightly around the serving base.

Notes

Pro tip: don’t skip the hot skillet sear—those browned bits deepen the flavor of the garlic butter sauce. Refrigerate leftovers in an airtight container for up to 3-4 days; reheat gently on the stovetop or microwave with a splash of broth if needed. Freezing is yes—freeze in portions for up to 2-3 months and thaw overnight in the fridge. For a lighter option, swap some butter for additional beef broth and finish with a smaller amount of butter at serving to keep it rich without as much fat.
