Ingredients for Beef and Broccoli Lo Mein
- Spaghetti Noodles: I like to use spaghetti noodles in this recipe because I always have them on hand, but you can use Lo-Mein noodles as well.
- Broccoli: This recipe calls for fresh broccoli florets, but you can use frozen broccoli and place it in the microwave to steam.
- Olive Oil: Extra virgin olive oil is always my first choice, but vegetable or coconut oil works well.
- Flank Steak: Slice flank steak against the grain. I also like to use stir fry beef that is already sliced.
- Minced Garlic: I’ve said this before, minced garlic in a jar is so easy to use and you always have it on hand.
- Carrots: I like to use pre sliced carrots to save time, or you can shred one large carrot.
- Brown Sugar: Adds a little sweet flavor to this recipe.
- Soy Sauce: I always use low sodium soy sauce when cooking. The salt content is much lower than regular soy sauce.
- Hoisin Sauce: Can be found down the Asian isle of your grocery store.
- Sesame Oil: Is commonly used in Asian flavors and is good to have on hand when you are cooking different Asian dishes.
- Ground Ginger: I prefer to use ground ginger for the milder flavor in this recipe.
- Red Pepper Flakes: Use more or less depending how spicy you prefer.
- Sesame Seeds: Sesame seeds are optional.
How to make beef Lo Mein
- Prepare Sauce: In a small mixing bowl whisk together brown sugar, soy sauce, hoisin sauce, sesame oil, ground ginger, red pepper flakes, and sesame seeds. Set aside.
- Cook Pasta: Fill a large pot with water and bring to a boil over medium-high heat. Add spaghetti noodles and cook according to package.
- Cook Broccoli: Add broccoli florets to the boiling water of noodles the last 5 minutes and cook until tender. Drain noodles and broccoli.
- Cook Flank Steak: While the pasta is cooking, cook steak by adding olive oil to a medium-large skillet. Add steak and cook until it is done and no longer pink.
- Add Garlic And Carrots: Add minced garlic and sliced carrots to skillet and cook for an additional 2 minutes.
- Combine: Add cooked spaghetti noodles, broccoli, and sauce to the skillet. Toss to combine all ingredients well.
- Serve: Serve immediately with extra sesame seeds and sliced green onions for garnish
