Set a large skillet over medium heat and add the olive oil. Once the oil shimmers and begins to smoke lightly, it’s ready.
Add the minced garlic to the hot oil and sauté for about 30 seconds until fragrant and golden around the edges, filling the kitchen with a pungent aroma.
Gradually add the fresh spinach in batches, using tongs to toss and wilt the leaves. Continue until the greens are vibrant and just tender, about 2-3 minutes.
If the greens seem dry or start sticking, splash in a teaspoon of water or broth and continue tossing to help them wilt evenly.
Sprinkle the salt and red pepper flakes over the greens, tossing again to distribute evenly.
Squeeze the fresh lemon juice over the greens and toss once more, brightening the flavors and adding a fresh zing.
Remove the skillet from heat and transfer the garlic sautéed spinach to a serving dish, allowing the greens to glisten with the flavorful oil and aroma.
Serve immediately while still warm, enjoying the fragrant aroma and tender, glossy greens.
