Cucumber salad can be thickened by adding some ingredients that will soak extra moisture and make the salad more creamy and thick. Here are a few possibilities:
Greek yogurt: Introducing Greek yogurt can help the cucumber salad become creamier and thicker. To achieve the ideal consistency, simply combine some Greek yogurt with the cucumber, herbs, and other ingredients.
Greek yogurt and sour cream are both ingredients that can be used to thicken and milk up a cucumber salad. Similar to how you would use Greek yogurt, use this.
Avocado: You can also thicken the salad and add some healthy fats by mashing up some ripe avocado and combining it with the cucumber and other vegetables.
Cornstarch: You can make a more conventional dressing for your cucumber salad by combining some cornstarch and water, stirring the combination until it is completely smooth, and then heating it in a saucepan until it thickens. Before combining it with the cucumber and other components, allow the mixture to cool.
Keep in mind to incorporate these components gradually and thoroughly combine the salad until you achieve the desired consistency.
