Bring a large pot of water to a rolling boil. Add noodles and cook according to package instructions until just al dente, then drain and set aside.
While the noodles cook, peel and finely mince the garlic until it’s almost paste-like; this helps it release more aroma and flavor during sautéing.
Heat the oil in a large skillet or wok over medium heat until it shimmers and starts to crackle softly.
Add the minced garlic to the hot oil. Sauté for about 1-2 minutes, stirring constantly, until fragrant and golden at the edges. Be careful not to burn it—this will turn bitter and ruin the flavor.
In a small bowl, whisk together soy sauce, toasted sesame oil, and lemon juice to create a glossy, flavorful sauce.
Pour the sauce into the skillet with the garlic and cook for about 30 seconds, allowing the flavors to meld and the sauce to warm up.
Add the drained noodles to the skillet. Toss everything together vigorously using a spatula or tongs, ensuring the noodles are evenly coated in the fragrant garlic sauce.
Cook for another minute, stirring constantly, until the noodles glisten and absorb the sauce, with a slight toasted aroma filling the air.
Transfer the noodles to a serving dish. Garnish with sliced scallions for a fresh, crisp bite and vibrant color.
Serve immediately while warm, allowing the fragrant garlic aroma to fill your kitchen and delight your senses.
