Gather your ingredients: thinly slice the garlic cloves and wash the fresh spinach thoroughly. Keep a small bowl nearby with the garlic slices ready to add.
Heat your wok or skillet over medium-high heat until hot, then add the oil and swirl to coat the surface evenly. Listen for a slight shimmer and a gentle sizzle.
Once the oil is shimmering and just starting to smoke lightly, add the thin slices of garlic. Stir constantly and cook for about 30 seconds to 1 minute until fragrant and golden around the edges. You’ll notice a rich aroma filling the kitchen.
Immediately add the fresh spinach to the pan. It will seem like a lot at first, but it wilts down quickly. Use your spatula or tongs to toss and stir vigorously, ensuring the garlic is evenly distributed among the greens.
Cook for 2-3 minutes, stirring occasionally, until the spinach is wilted, glossy, and tender. Look for crispy bits of garlic along the edges and a fragrant aroma. If the pan starts to dry out, add a small splash more oil or a teaspoon of water.
Season with a pinch of salt and crushed red pepper flakes, then remove from heat. Squeeze fresh lemon juice over the greens for a bright, zesty finish if desired.
Transfer the garlic spinach stir fry to a serving plate. Garnish with toasted sesame seeds and chopped scallions for extra crunch and flavor. Serve immediately while the garlic edges are crispy and the greens are tender.
