Costco Grain and Celery Salad Recipe Copycat: Celery Crowns Crunch Over Nutty Rum Cream Cheese

This Costco Grain and Celery Salad recipe copycat delivers the same crunchy, nutty, rum-infused perfection you love from the store—without the price tag. 💛 The secret lies in perfectly toasted grains, crisp celery crowns, and a velvety cream cheese dressing that ties everything together.

I've recreated this dish exactly as it comes from Costco, down to the texture and flavor balance.

The foundation starts with a mix of toasted wheat berries and wild rice, giving that distinctive nutty crunch. Fresh celery crowns (not chopped!) provide the signature crunch, while a blend of pecans and dried cranberries adds sweetness and texture.

What makes this salad truly special is the rum-infused cream cheese dressing—tangy, slightly sweet, and perfectly balanced.

What you'll end up with is a crunchy, satisfying salad that's heartier than most—ideal for potlucks, office lunches, or a light dinner. The grains stay perfectly toasted, the celery remains crisp, and the dressing clings to every bite.

It's the kind of dish that disappears quickly, leaving everyone asking for the recipe.

Best of all, this version is easier to make at home than you'd expect. With a few simple steps and quality ingredients, you'll have a salad that rivals (and improves upon) the original. Let's get started—your taste buds will thank you.

Ingredients for costco grain and celery salad recipe copycat

Sixteen ingredients. One iconic salad. The crunchy, nutty, rum-kissed copycat you've been craving.

The grains are non-negotiable here. Bob's Red Mill wheat berries and Lundberg wild rice blend are my go-tos—they toast perfectly and hold their texture. If you can't find wheat berries, farro works in a pinch, but it's not identical. Toast them in olive oil until golden (about 15 minutes), then cook in water until tender. Costco often sells bulk grains at a great price, so check there first. For celery crowns, look for the thickest stalks—Trader Joe's has the best selection, and you'll want about 2 large crowns for this batch.

No dark rum? Spiced rum or even vanilla extract at half the amount works, but you'll lose that signature depth. The cream cheese needs to be full-fat—Philadelphia brand is foolproof. For a lighter dressing, swap half the mayo for Greek yogurt, but trust me on the full-fat version. If you're making this ahead, prep the dressing separately until serving time—it keeps best that way. The cranberries? Dried, not fresh, and chop them small so they distribute evenly. Pecans should be toasted until fragrant—350°F for 8-10 minutes in a dry pan.

This salad tastes even better the next day—3-4 days in the fridge, actually. Store the grains and toppings separately, then toss with dressing just before serving to keep everything crisp. The dressing alone keeps for 5 days in an airtight container. For potlucks, I double the batch and serve it in a glass bowl with a metal scoop—it looks as good as it tastes. Leftovers? Toss with a fried egg for breakfast or use as a hearty side for grilled chicken.

Step-by-step instructions for Costco grain and celery salad

This copycat recipe delivers that signature Costco crunch and creamy texture at home.

Heat the 1 tablespoon olive oil in a large skillet over medium heat. Add the 1 cup wheat berries and 0.5 cup wild rice blend and toast for 3-4 minutes, stirring constantly until you smell that nutty aroma and see the grains begin to darken slightly. This step builds depth of flavor that plain cooking won't achieve.

Transfer the grains to a medium saucepan and add the 2.5 cups water. Bring to a boil, then reduce heat to low, cover, and simmer for 45-50 minutes until the grains are tender and the water is fully absorbed. Here's the thing—don't peek! Lifting the lid releases steam and can make the grains cook unevenly. When done, they should be al dente with no hard centers.

While the grains cook, trim the 2 whole celery crowns by cutting off the leafy tops and the root ends. Cut each crown lengthwise into 6-8 wedges, leaving the core intact so they hold their shape. You want crisp, vibrant celery that adds fresh crunch to balance the rich cream cheese dressing.

In a dry skillet over medium heat, toast the 0.5 cup pecans for 3-4 minutes until fragrant and lightly golden. Watch them carefully—they burn quickly! Transfer to a plate to cool, then roughly chop. Set aside along with the 0.5 cup dried cranberries (chopped if they're large) for the final assembly.

In a medium bowl, combine the 8 oz cream cheese, 0.5 cup mayonnaise, 2 tbsp dark rum, 1 tbsp lemon juice, 1 tbsp granulated sugar, 0.5 tsp salt, and 0.25 tsp black pepper. Use a hand mixer or whisk until completely smooth and creamy—this is your flavor foundation.

Here's where it gets good: The rum adds warmth while the lemon brightens the richness. Taste as you go—you might want to adjust the sugar slightly depending on your rum's sweetness. The dressing should be thick but pourable, coating a spoon easily without being gluey.

Once the grains are cooked and cooled, spread them on a large platter. Drizzle the rum cream cheese dressing evenly over the grains, using about ¾ of the total amount. Gently fold everything together with a spatula until the dressing coats the grains evenly.

Arrange the celery crown wedges in an attractive pattern over the grain mixture, then sprinkle the toasted pecans and dried cranberries evenly on top. Reserve the remaining dressing for serving. Cover and refrigerate for at least 2 hours—this chilling time lets the flavors meld and the celery stay crisp.

Before serving, drizzle the reserved dressing over the top and gently toss everything together one last time. The celery crowns should still have that satisfying crunch, while the grains maintain their chewy texture. This salad tastes even better the next day as the flavors develop further.

Real talk: The celery crowns are the star here—keep them fresh and crisp by not overcrowding the platter. Serve with extra dressing on the side for those who love it extra creamy. This copycat version delivers that perfect balance of textures and flavors you remember from Costco!

Best sauces and condiments for this dish

Rum Cream Cheese Base

Start with 8 oz full-fat cream cheese softened to room temperature—I like Philadelphia brand for its consistent quality. Blend it with 0.5 cup high-quality mayonnaise (like Hellmann's) until completely smooth. This mayo-cream cheese combo forms the rich foundation of the dressing. 🧀

The magic happens with the 2 tbsp dark rum—I recommend Captain Morgan for its balanced sweetness and spice notes. Add it gradually while mixing to avoid overpowering. The rum's caramel and vanilla undertones complement the cream cheese beautifully, creating that signature Costco depth.

Brightening the Dressing

Balance the richness with 1 tbsp fresh lemon juice and 1 tbsp granulated sugar. The lemon prevents the dressing from tasting too heavy, while the sugar rounds out any tartness from the rum.

I always taste at this stage—sometimes I add an extra pinch of salt or a splash more lemon depending on my rum's sweetness.

For extra tang, I sometimes add 1 tsp Dijon mustard to the mix. It cuts through the creaminess and adds complexity that makes this dressing truly special. The mustard should be well incorporated so it doesn't create any graininess.

Texture and Flavor Boosters

Toasted pecans aren't just for topping—they're a flavor enhancer in the dressing too. I pulse 2 tbsp finely chopped toasted pecans in a food processor until they become a fine powder, then mix them into the dressing. This adds nutty depth that mimics the Costco version's complexity.

For a subtle crunch factor, I also fold in 2 tbsp dried cranberries that have been finely chopped. These add a tiny bit of tartness and prevent the dressing from becoming too heavy. The cranberries should be small enough to distribute evenly throughout the salad.

Storage and Shelf Life

This dressing keeps beautifully in an airtight container in the refrigerator for up to 5 days. I always make extra because it's perfect for other salads or as a dip for fresh veggies. The flavors actually improve over time as the rum mellows and the spices meld together.

For best results, store the dressing separately from the salad components until serving. This prevents the celery crowns from becoming soggy and keeps the grains perfectly toasted. When ready to serve, simply toss the dressing with the grains and toppings just before plating.
