In a large saucepan over medium-high heat, bring the chicken broth to a boil.
Stir in the garlic powder and onion powder, mixing well to ensure the spices dissolve completely and distribute evenly throughout the broth.
In a separate small bowl, whisk together the cold water and corn starch until fully dissolved without any lumps.
Stir the corn starch mixture into the boiling broth and continue stirring until the mixture thickens to your desired consistency.
Add salt and pepper to taste, adjusting according to your preference. Serve immediately or store in the fridge.
Notes
Use quality broth for better flavor, adjust thickness by adding more broth or corn starch, taste before serving, and continually whisk to prevent lumps.
