Best Cornstarch Substitutes for Home Cooks: Expert Swaps for Sauces and Baking

Wheat Flour: Your Go-To Cornstarch Alternative

Wheat flour is the most convenient substitute for cornstarch (also known as cornflour) in savory dishes, and it's a staple in nearly every kitchen. While cornstarch often steps in for flour, you can reverse the roles effectively by sifting the flour first. For optimal results, use two parts wheat flour to one part cornstarch.

Instant Thickeners: Effortless, Gluten-Free Options

Modern instant thickeners, available at most stores, are ideal if you're gluten-intolerant. Complete with measuring spoons or dosing charts, just a small amount thickens sauces without added fat. Choose from a variety of flavors to suit your needs.

Tapioca Starch: Perfect for Sweet Recipes

For desserts like creams, tapioca starch—derived from cassava root—is an excellent natural thickener that also works in place of potato starch. Use it in a 1:1 ratio with cornstarch.

Roux: A Classic Thickening Technique

To replace cornstarch and add richness to cakes or sauces, make a roux with oil, flour, and unsalted butter. Here's how:

  1. Brown the oil and butter in a saucepan, gradually whisking in an equal amount of flour.
  2. Once it turns yellowish, thin with milk or broth to a smooth, thick consistency.

Kneaded Butter (Beurre Manié): Superior Binding Power

Kneaded butter, made from soft butter and flour, excels at thickening runny sauces just like cornstarch.

  1. Knead 30g soft butter with 30g flour into a smooth paste, form a ball, and chill for 20 minutes.
  2. Dissolve small pieces into your off-heat sauce, stirring vigorously.

Rice Starch: Ideal for Gluten-Free Baking

Rice starch shines in gluten-free baked goods, lightening dough without cornstarch while providing elasticity for tender, flavorful bread. Find it at organic stores; it's a reliable thickener and binder.
