What is a Slurry?

A slurry is generally made with liquid (often water or broth) mixed with either cornstarch or flour and added to a hot liquid to thicken it

Because a slurry is a concentrated starchy liquid it will thicken sauces and gravy. It can be mixed into apple juice to make a quick apple pie filling, or added to pan drippings or broth from cooked meat for a flavorful sauce or gravy.

Slurry vs. Roux

I often make a roux instead of a slurry when making gravy.

A roux contains equal amounts of flour and fat (instead of being made with flour and liquid). A roux is generally browned or cooked and then the liquid is added to the roux to thicken it (as opposed to the other way around with a slurry).

How To Make A Slurry

Cornstarch or Flour?

You can use either cornstarch or flour in a slurry and what it really boils down to is a personal preference (and the recipe you're making).

Cornstarch will produce a more clear/translucent liquid while flour will produce an opaque result. I personally find it easier to get a smooth result with cornstarch.

With either one, you will need to create a slurry , this just means mixing the thickener with water/broth before adding to the liquid.

Cornstarch Slurry

This is my personal preference as it's less likely to get lumpy (and I use this in countless recipes from beef stew to teriyaki sauce.

Mix equal parts cornstarch and water or broth (depending on the recipe).
Whisk into boiling liquid a little bit at a time until you reach desired consistency.
Let boil for at least 1 minute.

Flour Slurry

If using flour/water as your slurry, place it in a jar and shake well. This will help make sure you don't get lumps in your gravy, stew, or soup!

Place 3-4 tablespoons flour and ½ cup water or broth into a jar, shake VERY well to eliminate lumps.
Whisk into boiling liquid until you reach desired consistency.
Let boil for at least 1 minute.

How Do I Remove Lumps from a Slurry?

To avoid a lumpy result, make sure your slurry is very smooth before adding to your liquid and whisk constantly while adding.

If you've accidentally added some lumps, the best way to remove lumps is to strain the slurry through a fine mesh sieve. Another easy method is to scoop out as much liquid from the pan and blend in a small blender or food processor until smooth.
