Can I make the blue cheese dressing ahead of time?
Yes. Store the dressing in an airtight container in the refrigerator for up to 4 days. Whisk or shake before serving if it separates.
How do I keep the lettuce crisp?
Wash and dry the iceberg lettuce thoroughly, then chill it for at least 30 minutes before serving. Dress the salad just before eating.
Can I substitute blue cheese?
Yes. Gorgonzola, Danish blue, or crumbled feta work as replacements, though they'll shift the flavor profile slightly.
What's the best way to cook the bacon?
Bake it in a 400°F oven for 15–20 minutes until crispy, or fry it in a skillet over medium heat, turning occasionally. Drain on paper towels before crumbling.
Can I scale this recipe?
Yes. Double or halve all ingredients proportionally. The dressing ratio of 1/2 cup mayo to 1/4 cup buttermilk holds across any batch size.
