Penne with Roasted Cauliflower and Lemon Caper Piccata Sauce

This hearty pasta dish combines tender roasted cauliflower with a bright, tangy piccata sauce made from white wine, lemon juice, and capers. The cauliflower is roasted until golden and caramelized, adding depth and nutty flavors that pair beautifully with the sharp, acidic sauce. Served alongside a fresh mixed green salad with avocado and cherry tomatoes, this meal offers a perfect balance of comfort and freshness. The piccata sauce, enriched with butter and Dijon mustard, creates a silky coating that brings all the elements together into a satisfying weeknight dinner.

FAQ

Can I make this dish ahead of time?

The cauliflower can be roasted a day ahead and the sauce components prepared, but cook pasta fresh and assemble just before serving for best texture.

What if I don't have white wine?

Simply use additional stock in place of wine. The sauce will be less acidic but still flavorful with the lemon juice and capers providing brightness.

Can I freeze the leftovers?

The pasta dish can be frozen for up to 2 months, but the salad should not be frozen. Thaw pasta overnight and reheat gently on stovetop.
