What Makes Costco Quinoa Salad So Good? 

Costco salad tastes just as amazing as it looks. Don’t let all the healthy ingredients fool you. This vegan-friendly blend of quinoa, red lentils, brown rice, and plenty of fresh veggies tossed with a tangy dressing tastes much better than most sides and perfectly complements a variety of meat-based and vegetarian main courses.

Whether you are already a fan of the Quinoa Salad Costco sells or are just looking for something new, you will love this dish! This refreshing summer salad is perfect for picnics, potlucks, and backyard BBQs.

Why You Should Try This Recipe 

Sure, you can pick up a package of this healthy salad at your local Costco if you are a member, but there is no need to make a special trip to the store when you can whip up a batch at home.

Feel free to tweak the ingredients to suit your taste, like adding diced red onion, mung beans, fresh herbs like parsley, feta cheese, or swapping fresh tomatoes for sundried ones. Shaved broccoli also makes a good replacement for kale.

Costco Quinoa Salad Ingredients

For the delicious lemon dressing, you’ll need:

  • Fresh lemon juice 
  • Kosher salt 
  • Freshly ground black pepper 
  • Ground cumin 
  • Apple cider vinegar 
  • Vegetable oil

For the salad, you’ll need:

  • Roma tomatoes

  • Kale
  • Cilantro
  • Tricolor quinoa, cooked
  • Brown rice, cooked 
  • Red lentils, cooked

Ingredient Notes

Roma tomatoes are ideal in this salad, but any plum or grape tomato will work well. 

Each of the three kinds of quinoa that make up a tricolor blend has a unique flavor and texture. The different types add variety to the salad, but if you prefer, you can always use just only favorite. 

To put this salad together quicker and for easier meal prep, you can buy precooked quinoa, brown rice, and red lentils, but cooking them yourself is cheaper and not too difficult. 

You can substitute extra virgin olive oil for vegetable oil but note it will solidify when refrigerated.

What to Serve This With 

Since this is a light, very flavorful salad, it goes well with summery dishes like grilled chicken or fish. You can also serve it with steak to bring a little extra acidity to help balance the richness of the meat.

To keep it vegan, serve the salad with roasted root veggies to bring out the dish’s earthiness, or add richness by topping it with sliced avocado.

How Long Does It Last 

Quinoa Salad will stay good in the fridge for up to three days, but it is better to consume it within 24 hours after making it.
