High Protein Mongolian Beef Noodles

Ingredients You’ll Need
For this recipe, you’ll need simple pantry staples along with fresh ingredients that are easy to find:
For the Beef Marinade:
- 300g lean beef, thinly sliced
- 2 tbsp light soy sauce
- 1 tsp garlic powder
- 1/2 tsp black pepper
- 1/4 tsp baking soda
- 1 tbsp olive oil
- 1 tbsp cornstarch
For the Stir-fry:
- 3 cloves garlic, minced
- 3 green onions, chopped
- 1 small red onion, thinly sliced
- 2 tbsp soy sauce
- 1 tbsp oyster sauce
- 1/4 cup water
- 1 tsp cornstarch (mixed with 1 tbsp water)
- 200g cooked noodles (any variety, like rice noodles or soba)
- Chili flakes and sesame seeds for garnish
Step-by-Step Instructions
1. Marinate the Beef
Start by thinly slicing the beef. In a large bowl, combine light soy sauce, garlic powder, black pepper, baking soda, olive oil, and cornstarch. Mix the beef into the marinade, ensuring each strip is coated evenly. Let it marinate for at least 15-20 minutes. The baking soda helps tenderize the beef, giving it that restaurant-quality softness.

2. Cook the Beef
Heat a non-stick skillet over high heat. Once the pan is hot, add the marinated beef strips, being careful not to overcrowd the pan. Cook the beef for about 3 minutes on each side until golden and crispy. The high heat will create a nice sear on the outside while keeping the beef tender inside. Once cooked, set the beef aside on a plate.

3. Prepare the Stir-fry Base
In the same skillet, add a little more olive oil if needed, and toss in the minced garlic, chopped green onions, and sliced red onion. Stir-fry on medium heat for about 2-3 minutes until the garlic is fragrant and the onions are slightly caramelized.

4. Make the Sauce
Add soy sauce, oyster sauce, and water to the skillet, stirring everything together. Bring the mixture to a gentle simmer, then stir in the cornstarch slurry (cornstarch mixed with water). Allow the sauce to thicken for about 2 minutes. The result should be a rich, glossy sauce that coats the back of a spoon.
5. Combine the Ingredients
Once the sauce is ready, add the cooked beef back into the skillet, along with the cooked noodles. Toss everything together, ensuring that the noodles and beef are evenly coated with the sauce. This is the step where all the flavors meld together, creating a perfect harmony of savory goodness.

6. Garnish and Serve
To finish, garnish with chili flakes for a bit of heat and sesame seeds for a nutty crunch. Divide the dish into four equal servings, making it an ideal meal for prepping or serving family-style.
