Gather all ingredients.

Preheat the oven to 375 degrees F (190 degrees C).

Roll out crescent roll dough onto a 9x13-inch baking sheet, and pinch together edges to form the pizza crust.

Bake crust in the preheated oven for 12 minutes. Once finished cooking, remove crust from the oven and let cool for about 15 minutes without removing it from the baking sheet.

Combine cream cheese, mayonnaise, and dry Ranch dressing mix in a small mixing bowl. Spread the mixture over the cooled crust.

Arrange broccoli, tomatoes, bell pepper, cauliflower, shredded carrots, and Cheddar cheese over the cream cheese layer.

Chill for 1 hour, slice, and serve.
