Heat a large skillet over medium-high heat and add 1–2 tablespoons of olive oil or butter. When the fat shimmers, add aromatics like 1–2 cloves minced garlic or a pinch of red pepper flakes and cook until fragrant (10–20 seconds). Add washed, mostly dry spinach in a single layer or in batches — it will quickly collapse.
Toss or stir continuously for 1–2 minutes until leaves are wilted but still bright green. Finish with a squeeze of lemon juice, a pinch of salt, and a grind of black pepper. For richness, stir in a splash of cream or a tablespoon of grated Parmesan.
