Begin by washing and peeling one large English cucumber. Thinly slice it into rounds or half-moons, ensuring uniformity for even texture. Pat the slices dry with paper towels to keep your Cucumber Caesar Salad fresh and crunchy.

In a mixing bowl, combine 1/2 cup of mayonnaise, 1 tablespoon of freshly squeezed lemon juice, and 1 teaspoon of Dijon mustard. Use a whisk to blend these ingredients together until the mixture is smooth and creamy.

Add 1 clove of minced garlic and 2 tablespoons of grated Parmesan cheese to the dressing mixture. Season it with 1/4 teaspoon of freshly ground black pepper and 1/8 teaspoon of salt. Whisk everything together until the dressing is well-blended.

In a large bowl, add the dried cucumber slices. Pour the creamy dressing over them and toss gently but thoroughly, ensuring every cucumber piece is well-coated. The vibrant colors and creamy texture will make your salad visually appealing.

Just before serving, stir in 1/4 cup of croutons gently to avoid making them soggy. This will add a delightful crunch to your salad.

Transfer the assembled salad to a serving dish. For an extra special touch, garnish with additional Parmesan cheese and sprinkle a little more black pepper on top just before serving.
