🥘Ingredients
- 1 lb beef flank steak (about 1-inch thick)
- 2 tbsp olive oil
- 2 tbsp balsamic vinegar
- 1 tsp smoked paprika
- 1 tsp garlic powder
- 1 tsp onion powder
- 1 tsp salt
- 1 tsp black pepper
- 1 cup beef broth
- 1 cup tomato sauce
- 3 cloves garlic, minced
- 1 tbsp Worcestershire sauce
- 1 tbsp soy sauce
- 1 tbsp Dijon mustard
- 1 tsp dried thyme
- 1 tsp dried rosemary
- 1/2 cup beef fat or olive oil (for basting)
👨🍳Directions
-
1
Pat the beef flank steak dry with paper towels. In a bowl, whisk together olive oil, balsamic vinegar, smoked paprika, garlic powder, onion powder, salt, and black pepper. Rub the mixture evenly over the beef, coating it thoroughly. -
2
Place the beef in the slow cooker. Pour the beef broth into the bottom of the cooker, leaving a little space at the top to prevent splashing. -
3
In a separate bowl, combine tomato sauce, Worcestershire sauce, soy sauce, Dijon mustard, thyme, and rosemary. Stir in minced garlic and mix well. -
4
Pour the sauce mixture over the beef in the slow cooker. Add beef fat or olive oil to the top of the sauce. Cover and cook on low for 6 hours or until the beef is fork-tender and easily shreds with minimal effort. -
5
Remove the beef from the slow cooker and let it rest for 5 minutes before shredding with two forks. Discard any excess fat from the sauce if needed. Stir in the reserved beef fat or oil for extra richness.

❓ Frequently Asked Questions About Slow Cooker Beef Flank Steak with Garlic-Herb Sauce
How long should I cook the beef flank steak in the slow cooker?
Cook the beef flank steak on low for 4–5 hours or on high for 2–3 hours until tender. The internal temperature should reach 145°F (63°C) for medium-rare doneness. Stir the meat occasionally to prevent sticking.
Can I add any seasonings or marinades to the beef before slow cooking?
Absolutely. For extra flavor, marinate the beef flank steak in a mixture of 1 cup olive oil, 1/2 cup soy sauce, 1/4 cup Worcestershire sauce, 2 cloves minced garlic, 1 tsp black pepper, and 1 tsp smoked paprika for at least 1 hour before slow cooking. Alternatively, sprinkle with coarse salt and pepper before adding to the pot.
What should I serve with beef flank steak?
Beef flank steak pairs well with classic slow-cooker sides like mashed potatoes, roasted carrots, or a simple green salad. For a heartier meal, try cornbread or a creamy polenta. The tender texture makes it versatile for tacos, burritos, or even a simple stir-fry if you prefer.
How do I prevent the beef from drying out in the slow cooker?
To keep the beef moist, avoid overcooking—pull it out just before it reaches the target temperature. If the liquid evaporates, add a splash of beef broth or water. For extra tenderness, let the meat rest for 10–15 minutes before slicing.
