- ¼ teaspoon ground ginger
- ¼ teaspoon crushed red pepper flakes
- ¼ teaspoon pepper
- Green onion, for garnish

- In a medium skillet, heat olive oil over medium-high heat. Add the steak and cook until no longer pink.
- Add the garlic and shredded carrot to the skillet and cook for one additional minute until fragrant.
- In a small bowl, whisk together brown sugar, soy sauce, hoisin sauce, sesame oil, ground ginger, crushed red pepper flakes, and pepper until smooth.

Serving and Storage Tips
- Serve Immediately: This Garlic Beef and Broccoli Lo Mein tastes best served hot and fresh, right after tossing the noodles in the flavorful sauce.
- Garnish Before Serving: Sprinkle sesame seeds and chopped green onions just before serving for a restaurant-style finish.
- Storage: Store leftovers in an airtight container in the refrigerator for up to 3–4 days.
- Reheat Properly: Reheat in a skillet over medium heat with a splash of soy sauce or water to loosen the noodles. Avoid microwaving for too long, as it can make the noodles dry.
- Freezing: Freezing is not recommended because noodles and vegetables can lose their texture once thawed.
- Meal Prep Tip: Cook the noodles and sauce ahead of time and store separately. Toss them together before serving for the best flavor and consistency.
