In a bowl, whisk together soy sauce, brown sugar, and sesame oil.
Add 2 tablespoon of the sauce to a blender, along with pear, onion, garlic, and ginger. Blend until a paste forms and strain to separate the pulp from the liquid.
Add the liquid marinade to the beef, along with ¼ teaspoon salt and ¼ teaspoon pepper. Marinade for at least 30 minutes, up to overnight, stirring occasionally.
Stir Fry
Bring a pot of water to a boil. Have ready on the side while you start on the stir fry.
Pour 1 tablespoon cooking oil into a wok or large skillet and heat over high heat. When hot, add the beef in a single layer and don't move for 2-3 minutes to let sear. Flip, repeat, and transfer the cooked beef to a clean plate. Cook beef in batches if necessary. Then use a paper towel to clean out the pan.
Pour remaining oil into the pan and turn heat down to medium-high. Add onion and carrot, letting cook for 1-2 minutes. Meanwhile, drop the udon noodles into the boiling water and stir for 30 seconds to separate. Follow package instructions if using dry, shelf-stable noodles. Quickly drain.
Add the udon noodles into the pan with the vegetables along with the remaining soy sauce mixture. Stir-fry until noodles absorb the sauce, about 1-2 minutes.
Add beef and dark green onion segments in and keep stir-frying for an additional minute. Season to taste. Garnish with thinly sliced green onion and serve immediately.
Some cuts of beef, like flank or round steak, are tougher than others. Add ⅛ teaspoon of baking soda to the marinade to soften the meat.
Udon: Frozen udon noodles have a better texture, cook faster, and will hold up well in stir-fries. However, dry shelf-stable udon are easy to find and will work as well. Make sure to boil it slightly al dente so it doesn't become overcooked.
Substitutions:
Replace brown sugar with white sugar or honey.
If you can't find Korean pear, substitute it with any pear, apple, or kiwi.
