Why did my cheese sauce turn grainy?
Usually it’s one of two things: the heat was too high, or the cheese went in too fast. Keep the burner on low once the milk is warm, and add the cheese by handfuls, whisking until each addition melts before adding more. If the pot feels too hot, pull it off the heat for 30 seconds and keep whisking.
Can I use pre-shredded cheese?
You can, but it’s not ideal. Pre-shredded cheese is often coated with anti-caking agents that can make sauces less smooth. For the best melt, buy a block of cheddar and shred it yourself.
How do I make it spicier?
Add pickled jalapeño brine (1 teaspoon at a time), a pinch of cayenne, or finely diced jalapeños. If you want smoky heat, chipotle powder is also great.
How do I make it thinner or thicker?
For thinner sauce, whisk in more warm milk a tablespoon at a time. For thicker sauce, let it simmer gently for 30 to 60 seconds, whisking, until it tightens up.
Can I make it without flour?
Flour is what gives this sauce its reliable, scoopable body. If you’re avoiding flour, you can try a cornstarch slurry, but the texture will be glossier and a bit less “homestyle.”
How do I keep it smooth for a party?
Keep it on the lowest heat and whisk in a splash of milk if it thickens as it sits. If you’re serving it for a while, a small slow cooker or warming pot on low works great. Just don’t let it bubble hard, that’s when cheddar sauces can split.
Can I make it extra smooth like classic concession-stand nacho cheese?
Yep. This recipe is all about real cheddar and a homestyle texture, but if you want that ultra-silky, “perfect every time” melt, add a small handful of American cheese or a pinch of sodium citrate. It’s optional, not required, but it does make the sauce more heat-proof.
