Costco Broccoli Salad Recipe: Sweet Crunch With Creamy Dressing

This salad delivers the creamy texture and sweet crunch you love from the store version. My approach keeps it simple while maximizing flavor and texture contrast.

Fresh broccoli florets, crisp bacon bits, and a tangy dressing come together for a side dish that’s always a crowd-pleaser. The balance of sweet, savory, and crunch makes it irresistible.

The broccoli is the star here—Costco’s pre-cut florets save time and are consistently fresh (just give them a good rinse). For the cheese, sharp cheddar with vegetarian rennet is key for that tangy bite. I grab mine from Whole Foods if I’m being picky, but most grocery stores carry it now. The dried cranberries add sweetness, but look for ones without added oils at Trader Joe’s.

No vegetarian bacon bits? Crumbled tempeh bacon works great—just pan-fry it until crispy. Swap sunflower seeds for sliced almonds or pecans if you prefer. The dressing can handle substitutions too—Greek yogurt at half the amount replaces the sour cream. For a lighter version, low-fat mayo works, but the full-fat gives that classic creamy texture.

This salad holds up well, actually tastes better after 24 hours as flavors meld. Store in an airtight container in the fridge for up to 3 days. The sunflower seeds might soften a bit, but that’s the only trade-off. Perfect for make-ahead potlucks or lunches.

Step-by-Step Instructions for Costco Broccoli Salad

Here’s how I make this creamy, crunchy crowd-pleaser every single time.

Step 1: Prepare the Fresh Ingredients

Start by cutting the 8 cups broccoli florets into uniform, bite-sized pieces. I prefer florets that are about 1-inch across so each bite has a satisfying crunch. Don’t discard the stems—peel and slice them thinly for extra texture.

Finely chop the 0.5 whole red onion—this creates a mild, even flavor without overpowering the salad. To reduce the sharpness, soak the chopped onion in cold water for 5 minutes, then drain and pat dry. Cube the 8 oz sharp cheddar cheese into ¼-inch pieces so they distribute evenly throughout the salad.

Step 2: Whisk Together the Creamy Dressing

In a medium bowl, combine the 1 cup mayonnaise, 0.5 cup sour cream, 2 tbsp apple cider vinegar, 3 tbsp granulated sugar, 1 tbsp Dijon mustard, 0.5 tsp salt, and 0.5 tsp black pepper. Whisk until the mixture is completely smooth and slightly thickened.

Taste and adjust the seasoning if needed. The dressing should be tangy from the vinegar and mustard, slightly sweet from the sugar, and creamy from the mayonnaise and sour cream. If it’s too thick, you can thin it with a splash of water, but I find this consistency perfect for coating the broccoli without making it soggy.

Step 3: Combine All Ingredients and Chill

In a large bowl, combine the prepared broccoli, red onion, sharp cheddar cheese, 0.75 cup dried cranberries, 0.5 cup sunflower seeds, and 0.5 cup crispy vegetarian bacon bits. Pour the dressing over the top and fold everything together gently until evenly coated.

Cover the bowl with plastic wrap and refrigerate for at least 1 hour (though I prefer 2 hours if you have the time). This chilling step allows the flavors to meld together and the broccoli to soften slightly while maintaining its crunch. It also gives the dressing time to thicken and cling better to the ingredients.

Step 4: Serve and Enjoy

Give the salad a good stir before serving to redistribute the dressing and toppings. Each serving should have a generous mix of broccoli, cheese, cranberries, and sunflower seeds, with the creamy dressing tying everything together.

This dish tastes even better the next day, as the flavors continue to develop. Store leftovers in an airtight container in the refrigerator for up to 3 days. Just give it a stir before serving to refresh the texture.

Pro Cooking Tips for This Dish

Chopping Techniques

For consistent texture, cut broccoli florets into uniform 1-inch pieces. I use a chef’s knife with a rocking motion for efficiency. Don’t waste the stems—peel and slice them thinly for extra crunch.

Onion Prep Hack

Finely chop the red onion for even distribution. To mellow its bite, soak chopped pieces in cold water for 5 minutes, then drain and pat dry. This simple step makes a big difference in flavor balance.

Dressing Perfection

Whisk the dressing vigorously until completely smooth. I use a wire whisk and a deep bowl to prevent splashing. The apple cider vinegar and Dijon mustard need to fully emulsify with the mayonnaise and sour cream. 💡

Mixing Method

Fold the dressing into the salad gently using a spatula. This prevents breaking the broccoli while ensuring every piece gets coated. I start with half the dressing, mix, then add more as needed.

Chilling Time

Let the salad chill for at least 1 hour before serving. For best results, I recommend 2 hours. This allows the flavors to meld and the broccoli to soften slightly while keeping its crunch.

Serving Tip

Always stir the salad before serving to redistribute the dressing. The sunflower seeds and dried cranberries tend to settle at the bottom during chilling. A quick toss ensures every bite is perfect. 🥗
