Penne Overview

Penne is a tubular wheat-based pasta commonly used in baked pasta dishes, creamy sauces, and meat-based ragù. Traditional penne is high in carbohydrates and is not suitable for low-carb, keto, or diabetic-friendly eating in standard portions. Lower-carb alternatives include vegetable noodles, shirataki noodles, or hearts of palm pasta.
