Costco's service deli jalapeño mac & cheese is a creamy, made-in-store prepared side dish sold by the pound. It combines tender elbow macaroni in a rich, cheesy sauce with diced jalapeños for a spicy kick, offering a convenient ready-to-eat or heat-and-serve option.

This deli-prepared dish is ideal as a hearty side for gatherings, potlucks, or weeknight meals. The jalapeño addition gives classic macaroni and cheese a bold, slightly spicy flavor profile without overwhelming the creamy base.
