  • 3 tablespoons soy sauce

  • 2 ½ tablespoons white sugar

  • 2 tablespoons sesame oil

  • 2 teaspoons minced garlic

Stir Fry Ingredients:

  • 8 ounces sweet potato noodles

  • 4 ounces lean beef, cut into 2-inch long strips

  • 6 ounces fresh spinach

  • salt and ground black pepper to taste

  • 1 tablespoon vegetable oil, divided

  • 1 small sweet onion, thinly sliced

  • 4 mushrooms, stemmed and sliced

  • 1 small carrot, cut into matchsticks


  1. Whisk soy sauce, sugar, sesame oil, and garlic in a bowl until sugar is dissolved into sauce.

  2. Bring a large pot of lightly salted water to a boil. Cook sweet potato noodles in the boiling water, stirring occasionally until cooked through but firm to the bite, 6 to 7 minutes. Rinse noodles under cold water and drain. Transfer noodles to a bowl, add 2 tablespoons sauce, and toss to coat.

  3. Squeeze beef under running water until juices run clear. Mix beef and 1 tablespoon sauce together in a bowl.

  4. Bring a pot of water to a boil. Cook spinach in the boiling water until just wilted, about 1 minute. Drain quickly and transfer spinach to a bowl of cold water to stop the cooking process. Squeeze excess water from spinach, place spinach in a large bowl, and season with salt and pepper.

  5. Heat 1 teaspoon oil in a large skillet over medium-high heat; cook onion until fragrant but crisp, 1 to 2 minutes. Transfer onion to the bowl with spinach. Heat another 1 teaspoon oil in the same skillet. Cook mushrooms in the hot oil until lightly browned but still firm, 1 to 2 minutes; add to onion mixture. Heat remaining 1 teaspoon oil in the same skillet. Cook carrot in the hot oil until lightly browned but still crisp, 1 to 2 minutes; add to onion mixture.

  6. Cook and stir beef in the same skillet until browned, 1 to 2 minutes; add to onion mixture. Cook and stir noodles in the same skillet until heated through, 1 to 2 minutes; add to beef-onion mixture. Add remaining sauce to beef-noodles mixture and toss to coat using your hands.
