In a large bowl, combine the minced garlic, melted butter, soy sauce, Worcestershire sauce, dried thyme, black pepper, onion powder, and salt. Mix well until the ingredients are fully combined.
Add the beef cubes into the bowl, making sure each piece is coated evenly with the garlic butter mixture.
Transfer the coated beef cubes into the crockpot, spreading them out evenly.
Cover the crockpot with the lid and set it to low heat. Cook for 6-8 hours or until the beef is tender and flavorful.
Once cooked, give the beef bites a gentle stir to coat them in the buttery juices.
Serve hot, garnished with freshly chopped parsley for an added burst of color and flavor.
Notes
Adjust salt to taste and serve with fresh parsley for garnish.
