A super quick and flavorful udon stir fry recipe that serves as a great base to use up any proteins or vegetables you have on hand. It really doesn't get easier than udon ready in less than 15 minutes!
Boil a pot of water and cook 2 packs of udon noodles according to package instructions. Pay attention to the cooking time! Frozen udon noodles cook very quickly.
While you are waiting for the water for the udon noodles to boil, start cooking your beef (or protein of choice). In a large skillet, heat the 2 tbsp oil on medium-high heat and saute the beef until all pieces are browned. Add in 2 tbsp soy sauce, 2 tbsp oyster sauce, 2 tsp brown sugar, and 2 tsp sriracha. Stir until everything is evenly combined.
Add in the onion, garlic, and bok choy to the beef sauce mixture at the same time you put the udon noodles into the boiling water. This way we won't overcook the vegetables while waiting for the noodles to cook.
Right when the udon is done boiling, add the cooked noodles to the sauce mixture. Toss to combine, stirring frequently until sauce has thickened and absorbed into the noodles (~1-2 minutes). Serve immediately.
