Rinse broccoli under cold water and dry well using paper towels or a salad spinner.
In a large bowl, combine chopped broccoli, shredded cheddar, diced onion, and chopped bacon.
In a small bowl, whisk together the mayonnaise, apple cider vinegar, and sugar until smooth.
Pour the creamy dressing over the broccoli mixture and stir gently until fully coated.
Cover and refrigerate for at least 2 hours to let the flavors develop.
Stir again before serving and enjoy cold.
Notes
– This broccoli salad gets better after chilling, so make it a few hours ahead or even the night before. – For the best texture, chop broccoli into small, bite-sized florets. – Let the bacon cool completely before mixing to keep it crisp. – Red onion gives a stronger bite; sweet onion is a milder option. – Store leftovers in an airtight container in the fridge for up to 3 days. – Apple cider vinegar adds depth to the dressing, but white wine vinegar works too. – Use homemade mayo for the best flavor, or your favorite high-quality brand.
