Introduction
This slow cooker marinated beef recipe is a rich, savory, and incredibly tender dish that requires very little effort. Cubes of beef slowly cook in a bold marinade made with soy sauce, garlic, spices, and a touch of sweetness. As the meat simmers for hours, it absorbs all the deep flavors and becomes melt-in-your-mouth tender. It’s a perfect comfort meal for busy days because the slow cooker does all the work.
Ingredients
2 to 3 pounds beef chuck roast, cut into large cubes
1/2 cup soy sauce
1/4 cup olive oil
1/4 cup Worcestershire sauce
2 tablespoons brown sugar
2 tablespoons lemon juice
4 cloves garlic, minced
1 tablespoon Dijon mustard
1 teaspoon onion powder
1 teaspoon smoked paprika
1 teaspoon black pepper
1/2 teaspoon salt (optional depending on soy sauce)
1/2 teaspoon crushed red pepper flakes (optional for heat)
1 tablespoon cornstarch
2 tablespoons water
Instructions
Place the cubed beef into the slow cooker. Spread the pieces evenly so they cook uniformly.
In a medium bowl, combine soy sauce, olive oil, Worcestershire sauce, brown sugar, lemon juice, minced garlic, Dijon mustard, onion powder, smoked paprika, black pepper, salt, and red pepper flakes. Whisk everything together until the marinade is well blended.
Pour the marinade evenly over the beef cubes in the slow cooker. Toss gently to coat all the pieces with the sauce.
Cover the slow cooker with the lid and cook on low for 7 to 8 hours or on high for 4 to 5 hours. The beef will become extremely tender and flavorful as it slowly cooks.
About 20 minutes before serving, mix the cornstarch with water in a small bowl to make a slurry. Stir the slurry into the slow cooker to thicken the sauce slightly.
Cover again and allow the sauce to thicken for the remaining cooking time.
Method
Slow cooking allows the connective tissues in tougher cuts like chuck roast to break down gradually. This process creates incredibly tender meat while the marinade reduces into a rich, savory sauce. The combination of salty, sweet, tangy, and smoky flavors penetrates the beef deeply during the long cooking time.
