Ingredients

2/3 c. low-sodium soy sauce, divided
Juice of 1/2 Lime
3 tbsp. packed brown sugar, divided
2 tbsp. cornstarch, divided
Kosher salt
Freshly ground black pepper
1 lb. Sirloin (or flatiron, skirt) steak, sliced thin against grain
2 tbsp. vegetable oil
3 cloves of garlic, minced
1/3 c. low-sodium beef (or chicken) broth
2 tsp Sriracha (optional)
1 head broccoli, cut into florets
Sesame seeds, for garnish

Directions

  1. In a medium bowl, whisk 1/3 cup soy sauce, lime juice, 1 tablespoon brown sugar, and 1 tablespoon cornstarch until combined. Add steak, season with salt and pepper, and toss until steak is coated. Marinate 20 minutes. 
  2. In a large skillet over medium-high heat, heat oil. Add steak in a single layer, working in batches if needed, and cook until seared, about 2 minutes per side. Remove steak and set aside. 
  3. Stir in garlic and cook until fragrant, about 1 minute. Stir in remaining 1 tablespoon cornstarch until garlic is coated, then stir in broth, remaining 2 tablespoons brown sugar, remaining 1/3 cup soy sauce, and Sriracha. Bring mixture to a simmer. Add broccoli and simmer until tender, about 5 minutes. Season sauce with salt and pepper (if necessary), then return steak to skillet.
