Costco Spinach Salad Recipe

I’ve always been a huge fan of the Costco Spinach Salad Recipe, but since I don’t live close to one, I decided to recreate it in my own kitchen.

After a few tries, I finally perfected the recipe, and my version is just as vibrant, crunchy, and satisfying as the original.

The combination of savory bacon, sweet cranberries, and a tangy poppy seed dressing makes it an absolute showstopper.

It has quickly become my go-to for a quick lunch or a light dinner that still feels incredibly special.

Ingredients

This section breaks down everything you need to create this delicious salad, from the fresh greens to the flavorful dressing.

  • 10 ounces Fresh Baby Spinach: Use fresh, pre-washed baby spinach for the best texture and flavor; avoid using frozen spinach as it will be wilted and watery.
  • 6 slices Bacon: Cooked until crispy and then crumbled, this adds a salty, savory crunch that is essential to the salad.
  • 1 cup Croutons: Homemade croutons are fantastic, but quality store-bought ones work well to add a necessary textural contrast.
  • ¾ cup Sliced Button Mushrooms: Make sure they are fresh and sliced thinly so they blend seamlessly with the other ingredients.
  • ½ cup Shredded Monterey Jack Cheese: Grating your own cheese from a block ensures a creamier melt and better flavor than pre-shredded options.
  • ¼ cup Dried Cranberries: These provide a chewy texture and a burst of tart sweetness to balance the savory elements.
  • ¼ cup Sliced Red Onions: Thinly sliced red onion adds a sharp, zesty bite that cuts through the richness of the dressing and bacon.
  • 3 Large Hard-Boiled Eggs: Sliced or roughly chopped, they add a creamy texture and a boost of protein.
  • ¾ cup Canola Oil: A neutral oil like canola is the base for the dressing, allowing other flavors to shine.
  • ½ cup White Vinegar: This provides the bright, acidic tang that defines the poppy seed dressing.
  • ¼ cup Granulated Sugar: Adds a touch of sweetness to balance the vinegar’s acidity in the dressing.
  • 1 Tablespoon Grated Yellow Onion: Grating the onion helps it dissolve into the dressing, infusing it with flavor without leaving large chunks.
  • 1 teaspoon Salt: Enhances all the flavors in both the salad and the dressing.
  • ¼ teaspoon Dry Mustard: Gives a subtle, tangy depth to the poppy seed dressing.
  • ½ Tablespoon Poppy Seeds: The star of the dressing, adding a mild nutty flavor and a distinctive look.

Note: This recipe makes enough for approximately 8 side-servings.

Variations

Feel free to get creative with these simple swaps to make the salad your own.

  • Add Protein: Make it a main course by adding grilled chicken, steak, or even some chickpeas for a plant-based option.
  • Cheese Please: Swap the Monterey Jack for crumbled goat cheese, feta, or sharp blue cheese for a different flavor profile.
  • Fruity Twist: Add sliced strawberries or mandarin oranges for a brighter, more summery feel that pairs wonderfully with the poppy seed dressing.
  • Nutty Crunch: Toss in some toasted pecans, candied walnuts, or slivered almonds for an extra layer of texture and nutty flavor.
  • Dressing Swaps: If you’re not a fan of poppy seed dressing, a warm bacon vinaigrette or a simple balsamic glaze would also be delicious.

How to Make Costco Spinach Salad Recipe?

Follow these simple steps to assemble a fresh, vibrant, and delicious salad that rivals the store-bought classic. From whisking the tangy dressing to layering the colorful ingredients, this recipe guides you through creating a perfect meal that’s packed with flavor and texture. It’s a straightforward process that yields impressive results every time.

Step 1: Prepare the Poppy Seed Dressing

Start by making the star of the show: the dressing. In a blender, combine the canola oil, white vinegar, granulated sugar, grated yellow onion, salt, and dry mustard. Blend these ingredients on high for about 30 to 60 seconds. You’re looking for the mixture to become fully emulsified, meaning it’s smooth and creamy. Once blended, add the poppy seeds and just pulse the blender a couple of times to distribute them evenly without grinding them up.

Step 2: Assemble the Salad Ingredients

Now it’s time to build the salad itself. In a large salad bowl, place your fresh baby spinach as the base layer. On top of the spinach, artfully arrange the crumbled bacon, croutons, sliced mushrooms, shredded Monterey Jack cheese, dried cranberries, sliced red onions, and the sliced hard-boiled eggs. Spreading the ingredients out ensures that every serving gets a little bit of everything.

Step 3: Toss and Serve

Just before you’re ready to eat, it’s time to bring everything together. Drizzle the desired amount of poppy seed dressing over the assembled salad. Use salad tongs to gently toss all the ingredients until the spinach leaves are lightly coated and everything is well-combined. Serve the salad immediately to ensure the spinach stays crisp and the croutons remain crunchy. It’s best to serve any extra dressing on the side.

Additional Tips for Making this Recipe Better

Over the times I’ve made this, I’ve picked up a few tricks to elevate it even more.

  • I find that toasting the nuts (if you add them) brings out their flavor immensely. A few minutes in a dry pan over medium heat does the trick.
  • To keep the salad from getting soggy, I always serve the dressing on the side, allowing everyone to add as much or as little as they like.
  • I prefer to cook the bacon in the oven on a wire rack. It makes it perfectly crispy and results in less mess than pan-frying.
  • For the best flavor, I let the dressing sit in the refrigerator for at least 30 minutes before serving. This allows the flavors to meld together beautifully.
  • I always wash and thoroughly dry my spinach, even if the bag says it’s pre-washed. A salad spinner is my best friend for this, as it prevents a watery salad.

If serving as a main course, pair it with a side of crusty bread to soak up any leftover dressing. It’s an excellent accompaniment to grilled chicken, steak, or a simple bowl of soup.
