Costco Broccoli Salad Recipe: Crunchy Sweet and Creamy Bites

This broccoli salad delivers that signature Costco crunch with a perfectly balanced creamy dressing. The secret lies in the fresh, crisp vegetables and just the right amount of sweetness to complement the tangy mayo base.

Every bite offers satisfying texture contrast – tender florets, crisp bacon, and chewy dried cranberries all coated in that rich, velvety sauce. It’s the ideal side dish for potlucks or summer barbecues.

Ingredients for Costco Broccoli Salad

Fresh vegetables and a creamy dressing make this salad unforgettable for any gathering.

The broccoli must be ultra-fresh for that signature crunch. Costco carries pre-cut florets that work well, but whole crowns from your local farmers market are even better—look for tight, deep green heads. The cheddar should be sharp and block-cut (pre-shredded has anti-caking agents that dull flavor). For the bacon, opt for thick-cut for better texture, or turkey bacon if you prefer a lighter option.

No sour cream? Greek yogurt at the same amount keeps the tang. Dried cherries can swap for cranberries (same quantity). Sunflower seeds allergic? Pepitas or chopped almonds add similar crunch. The vinegar can be red wine or rice vinegar—all work. For a sweeter dressing, bump the sugar to one-third cup, but start small and adjust.

This salad keeps well for 3-4 days in the fridge, though the broccoli softens slightly. Store in an airtight container with a paper towel on top to absorb moisture. The dressing can be made 2 days ahead—flavors meld beautifully. Not suitable for freezing.

Step-by-Step Instructions for Costco Broccoli Salad

This method ensures maximum crunch, balanced sweetness, and a creamy dressing that ties everything together perfectly.

Step 1: Prepare the Vegetables and Add-Ins

Begin by cutting the 2 lb Broccoli Crowns into small, uniform florets. Discard any tough stems as they can be fibrous. The smaller the florets, the more surface area for the dressing to cling to, ensuring every bite is well-coated.

Finely dice the 0.5 whole Red Onion to achieve a sharp bite without overpowering the salad. Soak the diced onion in cold water for 10 minutes to mellow its harshness, then drain well. Chop the 0.75 cup Dried Cranberries if they are particularly large, and measure out the 0.5 cup Sunflower Seeds and 1 cup Sharp Cheddar Cheese.

Step 2: Cook and Crumble the Bacon

Cook the 8 slices Bacon in a skillet over medium heat until crispy. Transfer to a paper towel-lined plate to drain excess fat, then crumble into small pieces. The bacon should be cooked until deeply browned and brittle—this ensures it retains its crunch even after being mixed into the salad.

If using turkey bacon as a vegetarian alternative, follow the same process but monitor closely, as it can burn more easily. Allow the crumbled bacon to cool completely before adding it to the salad to prevent wilting the greens or melting the cheese prematurely.

Step 3: Whisk Together the Dressing

In a medium bowl, combine the 1 cup Mayonnaise, 0.5 cup Sour Cream, 0.25 cup Granulated Sugar, 2 tbsp White Vinegar, 0.5 tsp Salt, and 0.5 tsp Black Pepper. Whisk vigorously until the mixture is smooth and fully emulsified.

The sugar should dissolve completely, and the dressing should have a glossy, slightly thick consistency. Taste and adjust the seasoning if needed, though the saltiness of the bacon and cheese will enhance the overall flavor balance once combined.

Step 4: Combine All Ingredients

In a large mixing bowl, add the prepared broccoli, drained red onion, dried cranberries, sunflower seeds, sharp cheddar cheese, and crumbled bacon. Pour the dressing over the top and fold everything together gently but thoroughly, ensuring all components are evenly coated.

Avoid overmixing, as this can cause the broccoli to break down and release excess moisture, which may dilute the dressing. The final salad should glisten slightly, with each ingredient distinctly visible and well-distributed.

Step 5: Chill and Serve

Cover the bowl and refrigerate for at least 1 hour to allow the flavors to meld and the dressing to thicken slightly. This chilling step is essential for achieving the creamy texture promised—it lets the broccoli absorb some of the dressing without becoming soggy.

Give the salad a final toss before serving to redistribute the dressing. The ideal serving temperature is cold, with every bite delivering a harmonious mix of crunchy, sweet, and creamy elements.

Midwest Classic

In the Midwest, this salad shines at potlucks and church gatherings. I remember my aunt always adding ½ cup chopped red grapes for extra juicy sweetness. The key is keeping the broccoli florets large for that signature rustic look. 💛

West Coast Twist

California versions frequently include ½ cup shredded carrots and ¼ cup raisins for added color and texture. The dressing might use Greek yogurt instead of sour cream for a lighter, tangier profile.

Everything’s bigger in Texas—including the flavor. I’ve seen versions with 1 cup shredded cheddar and 12 bacon slices for extra richness. Some even add 1 diced jalapeño for a spicy contrast to the sweet dressing.
