Ingredients for Costco Orzo Salad
Bright Mediterranean flavors start with orzo, feta, and crisp garden vegetables for this vibrant dish.
| Ingredient | Amount | Notes |
|---|---|---|
| Orzo Pasta 🍝 | 1 ½ cups | Dried, cooked al dente |
| Cucumber 🥒 | 1 whole | English or Persian, diced |
| Cherry Tomatoes 🍅 | 2 cups | Halved or quartered |
| Red Onion 🧅 | ½ whole | Thinly sliced, soaked in cold water |
| Kalata Olive Mix 🫒 | ¾ cup | Pitted, drained, chopped |
| Feta Cheese 🧀 | ¾ cup | Crumbled, full-fat preferred |
| Fresh Parsley 🌿 | ½ cup | Flat-leaf, finely chopped |
| Fresh Dill 🍃 | ¼ cup | Fresh, finely chopped |
| Extra-Virgin Olive Oil 🫒 | ½ cup | High-quality for dressing |
| Red Wine Vinegar 🍷 | 3 tbsp | Balances the richness |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed preferred |
| Dijon Mustard 🟡 | 1 tsp | For tangy dressing depth |
| Garlic Cloves 🧄 | 2 cloves | Minced for dressing |
| Dried Oregano 🌿 | 1 tsp | Mediterranean blend preferred |
| Salt 🧂 | 1 tsp | Diamond Crystal kosher salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
The orzo is the foundation—Costco’s bulk orzo is ideal for this scale, but any quality brand works. The feta must be full-fat and brined for authentic tang; Athens or President brands are reliable. For the olives, seek out Kalata olive mix at Mediterranean markets (or Costco’s own imported mix), which offers the perfect blend of briny, buttery, and peppery notes.
Substitutions are simple here. No English cucumber? A regular cucumber works, but seed and peel it first. Short on fresh herbs? Dried oregano at half the amount can pinch-hit, though fresh is ideal. For a nutty twist, add toasted pine nuts or slivered almonds. If avoiding dairy, swap feta for vegan feta—Violife melts and crumbles well.
This salad keeps beautifully—actually improves overnight as flavors meld. Store in an airtight container in the fridge for up to 5 days. The dressing may separate, so give it a stir before serving. Best served chilled or at room temperature.

Step-by-Step Instructions for Costco Orzo Salad
Master this Mediterranean-inspired dish with precise technique and layered flavors.
Step 1: Cook and Cool the Orzo Base
Bring a large pot of generously salted water to a rolling boil. Add the 1.5 cups orzo pasta and cook according to package instructions until al dente. This typically takes 8-9 minutes, but start testing at 7 minutes—you want the grains to retain a slight bite.
Drain the orzo immediately in a fine-mesh colander and rinse under cold water for 30 seconds to halt the cooking process. Shake off excess water, then transfer to a large bowl. The orzo should be room temperature before assembling the salad—this prevents wilting the fresh vegetables and maintains the dish’s vibrant texture.
Step 2: Prepare and Process Fresh Vegetables
Dice the 1 whole cucumber into uniform ¼-inch pieces. Halve or quarter the 2 cups cherry tomatoes depending on their size—aim for bite-sized portions. Thinly slice the 0.5 whole red onion, then soak the slices in cold water for 10 minutes to mellow their sharpness.
Finely chop the 0.5 cup fresh parsley and 0.25 cup fresh dill, stems removed. Drain the 0.75 cup Kalamata olive mix and chop the olives into rough ⅛-inch pieces. This size ensures every forkful contains a balanced distribution of flavors and textures. Pat all vegetables dry with paper towels to prevent watering down the dressing.
Step 3: Whisk the Mediterranean Dressing
In a medium bowl, combine the 0.5 cup extra-virgin olive oil, 3 tbsp red wine vinegar, 2 tbsp lemon juice, 1 tsp 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 for 45-60 seconds until the dressing emulsifies and thickens slightly. The mixture should appear creamy with no visible separation. Taste and adjust seasoning if needed—remember the feta cheese will add additional saltiness, so err on the side of under-seasoning at this stage.
Step 4: Assemble and Marinate the Salad
Add all prepared vegetables to the bowl with cooled orzo. Pour ¾ of the dressing over the mixture and toss gently with a silicone spatula. Sprinkle the 0.75 cup crumbled feta cheese over the top and fold in carefully to maintain visible feta chunks.
Drizzle the remaining dressing over the salad and toss once more. Cover the bowl with plastic wrap and refrigerate for at least 1 hour, or up to 4 hours for optimal flavor development. This resting period allows the orzo to absorb the dressing and the vegetables to soften slightly.
Pro Tips For Making Costco Orzo Salad
- Salt the Orzo Water: Use at least 1 tablespoon of salt per quart of water—this is your only chance to season the pasta itself, and under-salting leaves the dish flat. I learned this the hard way after making bland batch after bland batch.
- Seed the Cucumbers: Sounds tedious, but it works: scoop out the seeds before dicing to prevent a watery salad. After my first soggy attempt, I now do this every time.
- Shock the Orzo: Drain the orzo, then rinse it under cold water to stop the cooking and remove excess starch—this keeps the grains separate and the texture perfect. Yes, even if you’re impatient like me.
- Soak the Onions: Toss the diced red onion in cold water for 10 minutes to mellow the sharpness. My grandmother swore by this, and she was right: it makes the flavor way more balanced.
Storing and Reheating costco orzo salad
Refrigerator Storage
Let your salad cool completely before transferring to an airtight container. I use glass containers with locking lids to keep flavors fresh. Store in the fridge at 40°F or below for up to 5 days—the flavors actually improve as they meld together. ❄️
Freezer Storage
This dish doesn’t freeze well due to the fresh vegetables and dressing, which can become mushy and separate upon thawing. If you must freeze, portion into single-serving containers and consume within 1 month for best texture.
Reheating Not Needed
This salad is best served cold or at room temperature. Simply remove from the fridge 30 minutes before serving to take the chill off. If it’s been stored for several days, give it a good stir to redistribute the dressing.
Reviving Leftovers
If the salad seems dry after storage, drizzle with 1-2 tbsp extra-virgin olive oil and 1 tbsp red wine vinegar. Toss gently to refresh the flavors. I often add a squeeze of lemon juice for brightness. 💡
Storage Tips
Avoid adding feta cheese until ready to serve if storing longer than 2 days—this prevents it from absorbing too much dressing. Keep the red onion slices soaked in a small container of cold water in the fridge until assembly to maintain crispness.

Frequently Asked Questions
Can I make this salad ahead of time?
In fact, it tastes even better the next day. Prepare and refrigerate for up to 5 days in an airtight container. The flavors meld beautifully over time.
What can I substitute for Kalamata olives?
Green olives or black olives work well. For a different twist, try chopped sun-dried tomatoes or capers. Each adds a unique briny depth to the dish.
Why soak the red onion?
Soaking mellows the sharp bite and removes some of the pungency. This makes the onion more palatable while keeping its crisp texture. 10 minutes in cold water does the trick.
Can I use a different type of pasta?
Yes, small shapes like ditalini or acini di pepe work well. Avoid large pasta, as it won’t distribute evenly with the vegetables.
