I’ve always been a huge fan of the sweet kale salad kit from Costco, and I think the real star is the poppy seed dressing. After realizing I could make it at home, my salad game completely changed.

This recipe is my attempt to recreate that magic, and I think I’ve come pretty close. It has that perfect balance of tangy and sweet that makes any salad irresistible. Now, I can whip it up anytime I want, and it only takes a few minutes.

Ingredients

This simple dressing uses pantry staples to create a flavor that’s anything but basic. Here’s what you’ll need to bring this copycat recipe to life.

1/2 medium lemon – You will use both the zest and the juice for a bright, citrusy kick. Fresh is always best for flavor.
1/2 medium orange – The juice from a fresh orange adds a natural sweetness that balances the tanginess of the vinegar.
1 large egg yolk – This is the key to a creamy, emulsified dressing. It helps bind the oil and vinegar together.
1/4 cup vegetable oil – A neutral oil like vegetable oil allows the other flavors to shine through without overpowering them.
1 tablespoon apple cider vinegar – This provides the signature tangy flavor that cuts through the sweetness.
1 1/2 teaspoons poppy seeds – These add a subtle nutty flavor and a delightful texture with every bite.
1/2 teaspoon kosher salt – Kosher salt enhances all the flavors in the dressing. You can adjust this to your taste.
1/2 teaspoon honey – Just a little bit of honey adds a smooth sweetness that complements the citrus.
1/4 teaspoon onion powder – This gives a savory depth of flavor that you might not notice but would definitely miss.
1/4 teaspoon freshly ground black pepper – For a touch of mild spice to round out the dressing.

Note: This recipe makes approximately 1/2 cup of dressing, enough for about 4 servings.

Variations

One of the best things about making dressing at home is how easily you can customize it. Here are a few ideas to get you started.

Make it Egg-Free: If you want to omit the egg yolk, you can still achieve a creamy texture. Simply add 1/4 teaspoon of dry ground mustard to act as an emulsifier.
Switch Up the Oil: While vegetable oil is a great neutral choice, you can substitute it with other oils. Avocado oil or a light olive oil work well without adding too strong a flavor.
Adjust the Sweetness: If you prefer a less sweet dressing, you can reduce the amount of honey or substitute it with maple syrup for a different flavor profile.
Add Some Herbs: For an extra layer of flavor, consider adding finely chopped fresh herbs like chives or parsley.

Equipment You Need

You don’t need any fancy gadgets to make this dressing. Just a few basic kitchen tools will do the trick.

Jar with a Lid: The easiest way to mix the dressing is by shaking it vigorously in a sealed jar.
Measuring Spoons and Cups: For accurately measuring all the ingredients to get the perfect flavor balance.
Citrus Juicer and Zester: To get the most juice and zest from your lemon and orange.

Making this dressing is as simple as measuring and shaking. This method ensures all the ingredients emulsify into a perfectly creamy and delicious final product.

Prepare the Citrus

First, get your citrus ready. Finely grate the zest from half a medium lemon until you have about 1/2 teaspoon. Then, juice the same lemon half to get 1 teaspoon of juice. Next, juice half of a medium orange until you have 2 tablespoons of fresh juice.

Combine the Ingredients

Add the lemon zest, lemon juice, and orange juice to a jar or container with a tight-fitting lid. To this, add the large egg yolk, vegetable oil, apple cider vinegar, poppy seeds, kosher salt, honey, onion powder, and black pepper. Don’t worry about mixing them just yet; simply add them all to the jar.

Shake and Emulsify

Seal the jar or container tightly. Now for the fun part: shake it vigorously for about 30 seconds. You’ll see the ingredients transform from a separated mixture into a beautiful, creamy, and fully combined dressing. Give it a quick taste and add a little more salt if you think it needs it.

Additional Tips for Making this Recipe Better

Over time, I’ve found a few little tricks that make this already great recipe even better. I hope these personal tips help you perfect your own batch.

Let it Rest: I’ve noticed the flavor gets even better if you let the dressing sit in the fridge for at least 30 minutes before serving. This gives the ingredients time to meld together.
Use Room Temperature Ingredients: I find that using a room temperature egg yolk helps the dressing emulsify more easily and creates a creamier consistency.
Don’t Skip the Zest: I made this once without the lemon zest because I was in a hurry, and it just wasn’t the same. The zest adds a fragrant citrus note that really brightens the entire dressing.
Adjust to Your Liking: The first time I made this, I followed the recipe exactly. Now, I sometimes add a tiny bit more honey if my orange isn’t very sweet or an extra splash of vinegar if I want more tang. Don’t be afraid to make it your own!

How to Serve Costco Poppy Seed Dressing Recipe

This dressing is incredibly versatile and can be used in many ways beyond the classic kale slaw. For the best presentation, drizzle it evenly over your salad just before serving. A sprinkle of extra poppy seeds or some fresh herbs on top can add a nice visual touch and a little extra flavor.

It’s fantastic on a simple green salad, as a dip for fresh vegetables, or even drizzled over grilled chicken or fish. Its sweet and tangy profile pairs wonderfully with salads that include fruits like apples or cranberries and nuts like almonds or walnuts.

Make Ahead and Storage

This dressing is perfect for making ahead of time, so you always have a delicious, homemade option ready to go. Proper storage is key to keeping it fresh and tasty.

Store the dressing in an airtight container, like a mason jar, in the refrigerator. It will stay fresh for up to 3 days. The ingredients may separate a bit upon chilling, so just give it a good shake before each use to restore its creamy texture. I do not recommend freezing this dressing, as the emulsion will break upon thawing, resulting in a separated and undesirable texture.
