Start by peeling and finely mincing your garlic cloves. This helps release their aroma quickly when they hit the hot oil.
Heat the olive oil in a large skillet over medium heat until it shimmers gently, signaling it's ready for the garlic.
Add the minced garlic to the hot oil and cook, stirring constantly, until fragrant and just golden, about 30 seconds. The garlic should smell warm and nutty, and you’ll hear a gentle crackle.
Quickly add the washed spinach to the skillet, a handful at a time if needed. Use tongs or a spatula to toss and coat the leaves in the fragrant garlic oil, allowing them to wilt slightly.
Cook the spinach for about 2-3 minutes, stirring gently, until the leaves are tender, glossy, and wilted but still vibrant green. You’ll notice the volume decrease as the leaves soften.
Squeeze fresh lemon juice over the greens, then season generously with salt and freshly cracked black pepper. Add a pinch of red pepper flakes if you like a bit of heat.
Toss everything together for a few seconds to evenly distribute the seasonings and flavors. The spinach should look shiny and feel tender to the touch.
Remove from heat and transfer the garlic sautéed spinach to a serving dish. Serve immediately while warm, enjoying the rich garlic aroma and tender texture.
