Cook the spaghetti according to package instructions until al dente. Drain and set aside.
In a large skillet over medium-high heat, brown the ground beef until fully cooked. Drain any excess grease.
Reduce the heat to medium and add the minced garlic, 1 tablespoon soy sauce, chopped celery, sliced red onion, matchstick carrots, salt, and sugar. Sauté until the vegetables are tender-crisp, about 3–4 minutes.
Add the cooked spaghetti to the skillet and toss to combine with the beef and vegetables.
In a small bowl, whisk together the sesame oil, rice cooking wine, and 1 tablespoon soy sauce. Pour the sauce over the spaghetti mixture and stir well to coat everything evenly.
Simmer for an additional minute to allow the flavors to meld.
Serve hot and enjoy!
Enjoy!
