  • 14 oz Box Lo-Mein Noodles
  • 2 lbs Beef Sirloin Cut Thin
  • 2 Cups Broccoli
  • 1 Carrot
  • ¼ Cup Green Onions
  • 3 Cloves Garlic
  • ½ Cup Soy Sauce
  • ½ Cup Rice Vinegar
  • 2 Tbsp Oyster Sauce
  • 2 Tbsp Brown Sugar
  • 2 Tbsp Cornstarch
  • 2 Tbsp Sesame Oil
  • Sesame Seeds (optional)
  • ½ Cup Water


  • Preheat the oven to 400°. Line a sheet pan with foil and then parchment.
  • Bring a pot of water up to a boil. When water is at a full boil. Cook Lo-Mein noodles per the box instructions. Drain and lay on the lined pan.
  • Place the stir-fry beef pieces into a bowl or food storage bag.
  • In a small bowl mix together soy sauce, rice vinegar, brown sugar, cornstarch, and pressed/minced garlic.
  • Pour half of the beef and broccoli sauce into the bowl or bag with the meat. Coat the beef with sauce and let sit.
  • Wash and chop broccoli into 1” pieces. Wash and peel carrot. Using the peeler, shave the carrot into long thin strips. Wash green onions. Remove the bottoms and cut into 1” pieces. Place vegetables on top of the noodles.
  • Pour the remaining stir fry sauce over the noodles and vegetables and toss to coat.
  • Add the marinated beef to the pan. Make sure to separate the beef pieces so they will cook evenly.
  • Add ½ cup of water to the bottom of the tray.
  • Cook at 400° for 20-25 minutes on the middle rack. Stir halfway through. When the broccoli beef is fully cooked, turn the broiler on high for 5 minutes to add a little crisp to the beef and noodles.
  • Finish with a sprinkle of sesame seeds, and serve.


Dissolve the cornstarch completely in sauce before using it. Cornstarch will not dissolve in hot liquids.
First, coat all of your ingredients the beef an broccoli stir fry sauce. Add the water to the bottom of the pan right before you put it in the oven. The water will create steam in the oven, and help soften the broccoli and keep the noodles from burning. It will ultimately evaporate and you will be left with an amazing Broccoli Beef Lo Mein.
