Start by bringing a pot of salted water to a boil and adding the eggs. Boil for 10-12 minutes until fully hard-boiled, then immediately transfer to an ice bath to stop the cooking process and make peeling easier. While the eggs cook, cook the bacon in a skillet over medium-high heat until crisp, about 8-10 minutes, turning occasionally. Once cooked, transfer to a paper towel-lined plate to drain, then crumble into bite-sized pieces once cooled. This parallel cooking saves time and ensures both proteins are ready simultaneously.
While the proteins finish cooking, prepare your fresh ingredients to streamline final assembly. Cut the chicken into 3/4-inch cubes, halve the cherry tomatoes, crumble the blue cheese into bite-sized pieces, and finely chop the fresh chives. Peel the cooled hard-boiled eggs and cut them into quarters. I like to prepare the avocados last—slice them in half lengthwise, remove the pit, scoop out the flesh, and cut into chunks just before serving to prevent browning.
Pour the blue cheese dressing into a small bowl and stir in the heavy cream, a little at a time, until you reach your desired consistency. The dressing should be pourable but still coat the salad components well. Taste and adjust seasoning with freshly ground black pepper if needed. I prefer to keep the dressing on the thicker side initially and let guests thin it slightly with extra cream at the table.
Arrange all the prepared components—cubed chicken, crumbled bacon, tomato halves, blue cheese crumbles, egg quarters, and avocado chunks—on a serving platter or in a large bowl, grouping them by ingredient for visual appeal and classic cobb presentation. Sprinkle the fresh chives over the top for a bright garnish. Serve the dressing on the side, allowing diners to dress their portions to taste and keep the salad crisp.
