Gather all your ingredients: minced garlic, fresh spinach, oil, salt, chili flakes (if using), soy sauce, and lemon juice. Preheat your wok or skillet over high heat until shimmering.
Add the oil to the hot pan, swirling it around to coat the surface evenly. Wait until it starts to shimmer—this signals it's ready for the garlic.
Add the minced garlic to the pan. Sauté for about 15-20 seconds, stirring constantly until fragrant and just turning golden. The aroma should be sharp and inviting, and you may hear a gentle sizzle.
If desired, sprinkle in chili flakes now for some heat. Cook for another 10 seconds, stirring to release their spicy aroma without burning the garlic.
Quickly add the fresh spinach in batches, using tongs or a spatula to toss and coat the leaves with garlic and oil. Continue tossing for 30-40 seconds until the spinach wilts and becomes vibrant green, with stems just tender.
Season with a pinch of salt and drizzle the soy sauce over the greens. Toss again to evenly distribute the flavors. The greens should be slightly glossy and tender but still retain their bright color.
Remove the pan from heat immediately. Squeeze fresh lemon juice over the greens and give everything a final toss. The bright aroma of lemon helps lift the flavors.
Serve the garlic spinach stir fry immediately while it’s still vibrant and crisp-tender. Enjoy the fragrant, colorful greens that came together in just minutes.
