When I was younger and learning how to cook, my main method of thickening soup was the one I learned from my grandma. Mix flour with water and add a bit of tomato sauce. Voila! Now, with time I’ve learned that whatever you add to the soup may change it’s flavor. Therefore, I’ve been experimenting with different methods over the years.

Then I’ve made a comprehensive list of all the methods I use in hopes it gives you some ideas too. These soup thickening methods work for stews (like beef stew), chili and all sorts of sauces (like tomato sauce, alfredo sauce, gravy, etc.).

Depending on the cooking method and ingredients used, you can add thickeners in the beginning, throughout or towards the end of cooking process. Personally I like to add mine in the beginning.

How to thicken all sorts of soups (stews, chili and sauces) – by Ingredient:

How to thicken soups, stews, chili and sauces with cornstarch (vegan):

  1. Mix equal parts cold water and cornstarch. Mix until fully blended. Stir in some more liquid (from soup or water) to make it more watery and easy to blend with the rest of the liquids. Then add to soup and continue cooking.

How to thicken soups, stews, chili and sauces with all-purpose-flour (vegan):

  1. Place a tbsp of olive oil (or any vegetable oil) in a sauce/soup pan, then add 1-2 tbsp of all-purpose-flour. Stir for a minute. Then add 1/2 cup of broth/water and mix. Then transfer to the meal and cook accordingly.
  2. Mix 1-3 tbsp all purpose flour with 1 cup hot meal liquid. Mix well to get rid of lumps ( I use a fork). Then add to remaining meal and stir well to combine.

TIP: Sometimes when (hot) liquid is mixed with flour it gets lumpy. You can avoid that by adding liquid slowly and stirring constantly. Or, by blending some of the meals liquid and flour with a hand mixer to get rid of the lumps.

The above methods work with oat flour too (or gluten free flour options).
