Costco Orzo Salad Recipe: Mediterranean Freshness in Every Bite

This Mediterranean-inspired orzo salad captures the vibrant flavors of a Costco favorite with a homemade touch. The combination of tender orzo, crisp vegetables, and tangy feta creates a dish that’s as satisfying as it is refreshing.

I’ve refined this recipe to balance bold Mediterranean herbs with bright citrus notes, ensuring every bite is packed with flavor. The secret lies in letting the orzo cool completely before mixing, so it absorbs the dressing without turning mushy.

What you’ll love most is how this salad holds up—perfect for meal prep, picnics, or serving as a side at your next gathering. The textures stay crisp and the flavors deepen over time.

Ready in under 30 minutes, it’s a no-fuss dish that delivers on taste and convenience.

Ingredients for Costco Orzo Salad

A handful of fresh ingredients and pantry staples bring this Mediterranean favorite to life at home.

The orzo is key—De Cecco or Barilla hold their shape best after cooling. Grab the good feta (in brine, not pre-crumbled) from Costco or a Mediterranean market—it’s creamier. Cucumber and tomatoes should be firm and bright; if they’re mealy, skip ‘em. For the olives, Kalata are traditional but any briny black olive works (just avoid the canned ones).

No fresh dill? Dried at one-third the amount works, but fresh is worth it here. Out of red wine vinegar? Apple cider vinegar is a fine swap. The Dijon can be regular yellow mustard in a pinch, but you’ll lose some depth. If you’re not a fan of raw onion, soak the diced pieces in cold water for 10 minutes to mellow the bite.

This keeps like a dream—5 days in the fridge, and the flavors just get better. Best made a few hours ahead so the orzo soaks up the dressing. Doesn’t freeze well (the veggies go soggy), but it’s so easy you’ll want to make it fresh every time.

Step-by-Step Instructions for Costco Orzo Salad

This method delivers bright, fresh flavors with minimal effort—just like the original.

Step 1: Cook the Orzo to Al Dente

Bring a large pot of salted water to a rolling boil. Add the 12 oz Orzo Pasta and cook according to package instructions for al dente texture, usually about 8-9 minutes. Stir occasionally to prevent sticking.

Drain the orzo in a colander and rinse immediately under cold water. This stops the cooking process and prevents the pasta from becoming mushy. Shake off excess water and transfer to a large bowl to cool completely.

The orzo should be tender but still have a slight bite. If it’s too soft, it’ll turn to mush when mixed with the dressing later.

Step 2: Prep the Vegetables and Herbs

While the orzo cooks, halve the 1 cup Cherry Tomatoes and dice the 1 whole Cucumber into small, even pieces. Finely dice the 0.5 whole Red Onion—this ensures a subtle, even flavor without overpowering crunch.

Slice the 0.5 cup Kalata Olives in half if they’re whole, and crumble the 6 oz Feta Cheese into small chunks. Chop the 0.25 cup Fresh Parsley and the 2 tbsp Fresh Dill finely for even distribution.

Add all the prepped vegetables, olives, feta, parsley, and dill to the bowl with the cooled orzo. The colors should be vibrant and balanced—this is a salad that eats with the eyes first.

Step 3: Whisk Together the Dressing

In a small bowl or jar, combine the 0.5 cup Extra-Virgin Olive Oil, 3 tbsp Red Wine Vinegar, 2 tbsp Lemon Juice, 1 tbsp Dijon Mustard, and minced 2 cloves Garlic Cloves. Add the 1 tsp Dried Oregano, 1 tsp Salt, and 0.5 tsp Black Pepper.

Whisk vigorously until the dressing is fully emulsified. The mustard acts as a natural stabilizer, keeping the oil and vinegar from separating. Taste and adjust seasoning if needed—this is your chance to fine-tune the flavors.

Step 4: Combine and Let Flavors Meld

Pour the dressing over the orzo and vegetable mixture. Using a large spoon or spatula, gently fold everything together until evenly coated. Be thorough but gentle—you want every bite to have a little of each ingredient.

Cover the bowl and refrigerate for at least 30 minutes. This resting time allows the orzo to absorb the dressing and the flavors to develop. For the best results, let it chill for 2 hours if possible.

Give it one final stir before serving to redistribute the dressing. The salad should look glossy and fresh, with every ingredient shining.

Troubleshooting costco orzo salad

Orzo Too Mushy

If your orzo turns to mush, it likely overcooked. Drain it 1 minute early and rinse under cold water immediately. I use De Cecco brand—it holds shape better than generic. Next time, taste-test at 7 minutes for perfect al dente. 💡

Dressing Separates

The mustard in your dressing should stabilize it, but if it splits, whisk in 1 tsp warm water to re-emulsify. Always store dressed salad in an airtight container and give it a good stir before serving. This keeps the flavors balanced.

Vegetables Too Watery

Pat dry your diced cucumbers and tomatoes with a paper towel before adding. If using Costco’s pre-diced veggies, drain them in a colander for 10 minutes first. This prevents a soggy salad. Salt the veggies lightly and let sit for 5 minutes to draw out excess moisture.

Flavor Too Mild

If the salad tastes flat, add a pinch of salt or a splash of lemon juice. Let it sit for 30 minutes after adjusting—the orzo needs time to absorb the new flavors. I always taste before serving and tweak as needed.

Onion Overpowering

Soak diced red onion in cold water for 10 minutes to mellow its bite. For a subtler flavor, use green onions instead. The soaking trick works wonders and takes just minutes. 🥗

Cheese Clumping

Crumbled feta can stick together. Toss it with 1 tsp flour or cornstarch before adding to the salad. This keeps the pieces separate and evenly distributed. I learned this trick after too many clumpy salads.
