Ingredients

• 1 ½ pounds of flank steak, sliced thinly against the grain
• ¼ cup cornstarch
• ¾ cup low-sodium soy sauce
• ⅔ cup light brown sugar
• 4 cloves of minced garlic
• 1 tablespoon fresh ginger, minced
• ¼ cup water
• 2 large carrots, thinly sliced
• 3 stalks of green onions, sliced for garnish
• 2 teaspoons sesame oil
• 1 sheet fish gelatin, softened in water
• Optional: Red pepper flakes for a spicy kick

Ingredient Notes:

• Flank Steak: This cut is ideal because it’s flavorful and becomes tender during slow cooking. If you can’t find flank steak, sirloin or chuck roast works too.
• Soy Sauce: Low-sodium is preferred to control the saltiness, but feel free to use traditional soy sauce if you like a stronger flavor.
• Fish Gelatin: Enhances the sauce’s texture, making it luscious. If it’s hard to find, you can skip it, but I highly recommend it!
• Carrots: Besides adding color, they contribute sweetness. You can easily substitute with bell peppers or snap peas for a different twist.

Prep Note: Make sure the beef is at room temperature before cooking; this helps with even cooking.

Step-by-Step Instructions

1. Slice the steak

Thinly slice your flank steak against the grain. This is crucial for tenderness! Toss it with cornstarch in a large bowl until evenly coated.

2. Prepare the sauce

In your slow cooker, combine soy sauce, brown sugar, minced garlic, ginger, water, and sesame oil. Whisk it until the sugar dissolves—this step takes just about a minute.

3. Combine beef and veggies

Add the coated beef and sliced carrots into the slow cooker. Gently stir to ensure everything is well-coated in that delectable sauce.

4. Cooking time

Cover and set your slow cooker to low for 4-5 hours or high for 2-3 hours. You’ll know it’s ready when the beef is fork-tender.

5. Thicken the sauce

In the last 30 minutes of cooking, dissolve the softened gelatin sheet in a bit of warm water and stir it into the slow cooker. This will give the sauce that glossy finish!

6. Serve and enjoy

Once cooking is complete, stir everything and garnish with sliced green onions. Serve it over steaming rice or chewy noodles for an unforgettable experience.

Chef’s Tips:

• Browning the beef before adding it to the slow cooker can enhance its flavor, but it’s not necessary.
• If you’re rushed, use pre-sliced steak to cut down on prep time.

Expert Tips & Tricks
