Step 1: Cook the Bacon : Place the bacon in a cold skillet and cook over medium heat until crisp, flipping as needed. Drain on paper towels, then crumble once cooled.
Step 2: Prepare the Eggs : Place eggs in a saucepan and cover with cold water. Bring to a boil, then cover and remove from heat. Let sit for 10–12 minutes, then cool in ice water. Peel and chop the eggs.
Step 3: Prepare the Turkey : Use pre-cooked turkey breast or reheat leftover roasted turkey. Cut into cubes or shred into bite-sized pieces.
Step 4: Make the Ranch Dressing : In a bowl, whisk together mayonnaise, sour cream, buttermilk, mustard, and lemon juice until smooth. Add garlic, parsley, chives, dill, salt, and pepper. Mix well and chill for 15 minutes before serving for best flavor.
Step 5: Assemble the Salad : Arrange chopped lettuce on a large platter or in individual bowls. Line up ingredients neatly in rows: turkey, bacon, eggs, avocado, tomatoes, and cheese. Sprinkle lightly with salt and pepper.
Step 6: Dress and Serve : Drizzle with homemade ranch dressing just before serving. Alternatively, serve the dressing on the side so everyone can dress their own portion.
