This simple 3-ingredient cheese sauce is a versatile vegetarian staple that delivers a rich, velvety texture in minutes. By using evaporated milk and a touch of cornflour, you can achieve a stable, professional finish that won't split or become oily. It is the perfect speedy solution for those seeking a comforting dip without the faff of making a traditional flour-based roux on the hob.

Ideal for casual entertaining or a quick midweek treat, this homemade sauce can be customised with a kick of chilli for a classic Tex-Mex flavour. Serve it warm alongside crunchy tortilla chips, or pour it generously over steamed cauliflower for a quick and cheesy side dish. This reliable recipe is a must-have for anyone looking for maximum flavour with minimal effort.

Toss cheese and cornflour in a medium heatproof bowl. Pour evaporated milk over and cook in microwave on high 1 minute. Whisk and continue to cook in 30-second increments, whisking in between, until melted and smooth (about 2 minutes total).
