Ingredients

  • 2 tablespoons Argo cornstarch
  • 2 cups milk (whole or plant-based for vegan option)
  • 2 tablespoons butter (or vegan butter)
  • 1/2 teaspoon salt
  • 1/4 teaspoon white pepper (black pepper can be substituted)
  • 1/4 teaspoon garlic powder (optional for subtle flavor)
  • 1/4 teaspoon onion powder (optional)

Equipment

  • Medium saucepan
  • Whisk
  • Measuring spoons and cups
  • Wooden spoon or silicone spatula
  • Small bowl (for mixing cornstarch slurry)
  • Stove

Instructions

  1. Prepare the cornstarch slurry: In a small bowl, combine the 2 tablespoons of Argo cornstarch with 1/4 cup of milk. Whisk until completely smooth with no lumps. This slurry will help thicken your white sauce perfectly.
  2. Heat the butter and milk: In a medium saucepan over medium heat, melt the 2 tablespoons of butter. Once melted, pour in the remaining 1 3/4 cups of milk and warm it until it’s hot but not boiling, stirring occasionally.
  3. Add the slurry to the milk mixture: Slowly pour the cornstarch slurry into the hot milk while continuously whisking. This prevents lumps and ensures a smooth sauce.
  4. Cook and thicken: Continue heating the mixture over medium heat, whisking constantly. The sauce will start to thicken within a few minutes. Once it reaches a creamy consistency, remove the saucepan from heat.
  5. Season the sauce: Stir in the 1/2 teaspoon salt, 1/4 teaspoon white pepper, and if using, the garlic and onion powder. Taste and adjust the seasoning as desired.
  6. Serve or store: Your Argo White Sauce is now ready to use! Pour it over your favorite dishes or store it in an airtight container in the refrigerator for up to 3 days. Reheat gently before serving.

Tips & Variations

“For an even richer flavor, try substituting half the milk with cream or a plant-based alternative like cashew milk for a vegan twist.”

  • Vegan version: Use plant-based butter and almond, soy, or oat milk to make this sauce completely dairy-free.
  • Herb-infused: Add fresh herbs such as thyme, rosemary, or basil during the cooking process for an aromatic touch.
  • Cheesy white sauce: Stir in grated Parmesan or vegan cheese at the end to create a delicious cheese sauce perfect for pasta or vegetables.
  • Spicy kick: Add a pinch of cayenne pepper or smoked paprika to give the sauce some heat and depth.
  • Storage tip: If your sauce thickens too much after refrigeration, whisk in a little milk while reheating to restore its creamy texture.
