While this recipe has all the traditional mac ‘n’ cheese ingredients, it also got a few healthy additions. The roasted acorn squash is blended into a creamy cheese sauce—using strongly flavoured feta helps stretch the cheese flavour. We’ve also added in some cauliflower to replace some of the pasta. A sprinkling of buttery herb breadcrumbs and cheese adds a crisp topping that’s a welcome counterpoint to the vegetable-enhanced cheesy pasta mixture. When buying acorn squash, it should feel heavy for its size with smooth, dull skin and no soft spots. A lighter squash means its lost moisture and will be drier.
