Homemade nacho cheese sauce is easy to make and absolutely delicious – once you try it, you’ll never buy it in again!

Make it fresh, eat it warm and enjoy however you like – with nachos, in burritos or tacos, over the top of a chilli.

Nacho cheese sauce needs just a handful of ingredients to make. I like to top mine with a handful of pickled jalapeños, but that’s completely optional. If you like jalapeños, though, you’ll love the combination.

I like to serve my nacho cheese sauce as either a starter or light meal surrounded by nachos, cucumber and red bell pepper for dipping. You can’t beat it!

Ingredients, Substitutions and Variations

  • Butter, flour and milk – these make the bechamel sauce base. You can use salted or unsalted butter. Use plain flour. Skimmed, semi-skimmed or whole milk all work.
  • Cheese – some people use American cheese slices in their nacho cheese sauce. You absolutely can – but I don’t think it gives anywhere near the same rich flavour as if you use cheddar. Cheddar melts wonderfully and is easy to get hold of too. Win, win.
  • Smoked paprika – this is the key ingredient (other than the cheese!) It lifts the whole sauce.
  • Jalapeños– optional, for topping.

Nacho Cheese Sauce Top Tips

  1. Get ahead

    You can make this cheese sauce and keep it in the fridge for a week before using. Reheat thoroughly before eating.

  2. Whisk, whisk, whisk

    When you’re making the sauce, make sure you whisk all of the time. If it goes lumpy, don’t worry – just keep whisking and it will smooth out.

  3. To serve

    You can serve hot or cold, but it is far, far better served hot and I would really recommend you eat it this way.
