Description
A dump-and-go slow cooker dinner featuring tender flank steak in a sweet, savory, and zesty sauce with lemon and ginger. This recipe requires minimal prep time and delivers restaurant-quality flavor with ease.
Ingredients
Scale
- 2 lbs flank steak, trimmed and cut into 1-inch cubes
- 1/2 cup soy sauce (or tamari for gluten-free)
- 1/2 cup packed brown sugar
- 2 tbsp fresh ginger, minced
- 4 cloves garlic, minced
- 2 tbsp rice vinegar
- 1 tsp lemon zest
- 4 stalks green onions, separated (white parts for cooking, green tops for garnish)
- 1 tbsp sesame oil
Instructions
- Pat the flank steak dry and cut it against the grain into 1-inch cubes. Place in a large bowl.
- In a separate medium bowl, whisk together soy sauce, brown sugar, rice vinegar, minced garlic, and minced ginger until the sugar is mostly dissolved.
- Pour the sauce over the beef cubes and toss to coat evenly.
- Transfer the beef and sauce to the slow cooker insert. Add the white parts of the green onions and stir gently.
- Cover and cook on LOW for 6-7 hours or HIGH for 3-4 hours, until the beef is fork-tender.
- Optional: For a thicker sauce, mix 1 tbsp cornstarch with 1 tbsp cold water and stir into the slow cooker during the last 30 minutes of cooking.
- Turn off the slow cooker. Stir in sesame oil and the green onion tops. Let sit for 5 minutes before serving.
Notes
For best results, cook on LOW to keep the beef juicy. If using HIGH heat, check after 3 hours to prevent drying out. Trim all hard fat from the flank steak before cubing. Cut beef into uniform sizes for even cooking. The sauce reduces naturally, so no extra water is needed. Serve over steamed jasmine or brown rice.
