Costco Broccoli Salad Recipe: Crunchy Sweetness With Bacon and Cheese

This broccoli salad delivers the same satisfying crunch and creamy sweetness you love from the warehouse favorite. The combination of fresh broccoli, crisp bacon, and sharp cheddar creates a texture that keeps everyone coming back for more.

What makes this version special is the balance between the creamy dressing and the salad’s signature crunch. The dressing comes together in minutes with simple pantry staples, while the vegetables stay crisp even after mixing.

The result is a dish that’s both hearty and refreshing, perfect for potlucks or as a side to grilled meats. It holds up well in the fridge, making it ideal for meal prep or make-ahead gatherings.

Best of all, it tastes even better after a few hours as the flavors meld together. Here’s how to make this crowd-pleasing classic at home.

Ingredients for Costco Broccoli Salad

Fresh veggies, crispy bacon, and a creamy dressing make this salad irresistibly crunchy and sweet.

The broccoli is the star here. Costco has great pre-cut florets, but a whole head from your local market works just as well—look for tight, dark green florets with no yellowing. For the cheddar, Tillamook or Cabot sharp cheddar blocks give that perfect bite. Skip the pre-shredded kind (it’s coated in anti-caking agents). The bacon? Thick-cut from Whole Foods or your butcher’s counter if you want it extra crispy.

No bacon? Try turkey bacon or smoked tempeh for a similar smoky crunch. Dried cranberries can be swapped for chopped dried apricots or golden raisins. If you’re avoiding dairy, use vegan cheddar shreds (like Daiya) and a dairy-free mayo. The sunflower seeds can be pumpkin seeds or chopped almonds—whatever you’ve got in the pantry.

This keeps beautifully for 3-4 days in the fridge (the flavors get better overnight). Store it in an airtight container and give it a quick stir before serving. Perfect for meal prep or bringing to potlucks—just keep it chilled until ready to eat.

Step-by-Step Instructions for Costco Broccoli Salad

This no-cook salad comes together quickly with just a few simple steps and a little chopping.

Step 1: Prep the Broccoli and Bacon

Start by cutting the 2 lb Fresh Broccoli into small, bite-sized florets. Don’t discard the stems—peel them and chop into small pieces for extra crunch. I’ve found that smaller pieces distribute the flavors better in every bite.

Crumble the 12 pieces Crispy Cooked Bacon into small bits. The bacon should already be cooked until crisp, so this step is just about breaking it into even, pea-sized pieces that won’t overwhelm the salad.

Step 2: Mix the Creamy Dressing

In a medium bowl, whisk together the 1 cup Mayonnaise, ½ cup Sour Cream, 2 tbsp White Vinegar, and 3 tbsp Granulated Sugar until smooth. The mixture should be creamy with a slight tang from the vinegar and a touch of sweetness.

Add ½ tsp Salt and ½ tsp Black Pepper, then whisk again to combine. Taste and adjust seasoning if needed, but remember the sharp cheddar cheese and bacon will add additional saltiness to the final dish.

Step 3: Combine All Ingredients

In a large bowl, combine the prepared broccoli, crumbled bacon, 1.5 cups Sharp Cheddar Cheese, ½ whole Red Onion (finely diced), ¾ cup Dried Cranberries, and ½ cup Sunflower Seeds. The red onion should be finely diced to mellow its sharpness.

Pour the dressing over the top and fold everything together gently but thoroughly. You want every piece coated without crushing the broccoli or turning the cranberries mushy.

Step 4: Chill and Let Flavors Meld

Cover the bowl and refrigerate for at least 1 hour. This resting time allows the flavors to meld together and the broccoli to soften slightly, absorbing the creamy dressing.

I always make this salad a few hours ahead if possible—the longer it sits, the better it tastes. Just give it a quick stir before serving to redistribute the dressing that may have settled at the bottom.

Essential Equipment for Perfect Results

Mixing Bowls

I always use a large stainless steel mixing bowl (like Winco’s 5-quart) for the salad itself—it’s durable, won’t absorb odors, and gives plenty of room to fold everything together without spilling. A medium bowl works perfectly for whisking the dressing. 🥗

Cutting Tools

A sharp chef’s knife (my 8-inch Wüsthof is my go-to) makes quick work of the broccoli stems and red onion. For the cheese, I prefer a box grater over pre-shredded—it melts better and has no anti-caking agents.

Measuring Essentials

Accurate measurements matter for the dressing balance. I use OXO’s Good Grips measuring cups and spoons—the magnetic set stays organized in my drawer. The 1 cup and tablespoon measures get the most use for this recipe.

Storage Solution

An airtight container with a secure lid is crucial for keeping the salad fresh. I love Rubbermaid Brilliance containers—they’re leakproof and the clear sides let me see when it’s time to stir before serving.

Prep Shortcuts

If you’re short on time, a food processor with the shredding disc can quickly chop the broccoli stems. For the bacon, I often use kitchen shears to snip it into even pieces right in the pan after cooking. ⚡

Serving Style

A large serving spoon (I prefer wooden or bamboo) makes it easy to dish out portions without crushing the ingredients. The natural material also looks great when serving at gatherings.
