Believe it or not, the star behind this 5-ingredient supper is overcooked broccoli! We over-steam it here to give the broccoli a delicate and creamy texture, making it perfect for mashing, mixing with pasta water and tossing with pasta.
Overcooking the broccoli is key here; aim for a very soft texture that's easy to mash into a creamy sauce. Ensure your pasta cooking water is well-salted as it contributes significantly to the overall flavor of the sauce. Don't be shy about adding more pasta water to achieve the desired consistency for the sauce – it helps emulsify the butter, oil, and broccoli puree. Consider adding a pinch of red pepper flakes with the garlic for a subtle warmth, or a squeeze of lemon juice at the end for brightness.
