How to Thicken Anything

 

Slurry

Cornstarch + cold water, usually 1 tablespoon to 1 tablespoon.

Whisk it in at the end once the sauce is hot. It thickens fast and gives you that smooth, glossy finish.

Flour

Works, but it needs time. If you’re adding it directly, cook it for a few minutes or it’ll taste raw.

This is why most people end up accidentally making a roux anyway.

Roux

Equal parts fat and flour. Cook it first, then add liquid.

This is what gives sauces structure, not just thickness.

Reduction

No starch, no shortcuts. You’re just cooking off water.

It takes longer, but the flavor gets more concentrated as it thickens.

Egg yolk

Needs to be tempered. If you add it straight to heat, it scrambles.

Great for silky sauces, but you have to control the temperature.

Cream

Just let it simmer. As water evaporates, it thickens naturally.

Higher fat means a richer, more stable result.

Most people focus on “how to make it thicker”

But the better question is:

what kind of texture are you actually trying to get?

Save this for the next time you’re standing over the stove trying to fix a sauce.
