Ingredients

• 1 pound orzo pasta
• 1 English cucumber, diced
• 1 pint cherry or grape tomatoes, halved
• 1 red bell pepper, finely diced
• 1 yellow bell pepper, finely diced
• 1/2 cup red onion, finely minced
• 1/2 cup crumbled feta cheese (optional)
• 1/4 cup chopped fresh parsley
• 1/4 cup fresh lemon juice (from about 2 lemons)
• 1/2 cup extra virgin olive oil
• 2 cloves garlic, minced
• 1 teaspoon dried oregano
• Salt and freshly ground black pepper to taste

Step-by-Step Instructions

1. Cook the orzo pasta according to package directions until al dente. Drain the pasta immediately and rinse thoroughly with cold water to stop the cooking process and remove excess starch. Set aside to drain completely.
2. While the pasta is cooking, prepare the vegetables. In a large mixing bowl, combine the diced cucumber, halved tomatoes, diced red and yellow bell peppers, and minced red onion.
3. In a small jar or bowl, whisk together the dressing ingredients: lemon juice, extra virgin olive oil, minced garlic, dried oregano, salt, and pepper. Taste and adjust seasoning as necessary—it should be quite zesty.
4. Add the cooled, drained orzo to the large bowl with the mixed vegetables.
5. Pour the lemon vinaigrette over the orzo and vegetables. Toss gently until everything is evenly coated.
6. Gently fold in the crumbled feta cheese (if using) and the fresh chopped parsley.
7. For the best flavor, cover the bowl and refrigerate for at least 30 minutes to allow the flavors to meld before serving.

Expert Tips / Pro Tips

To ensure your Rainbow Orzo Salad has the best texture, make sure you rinse the cooked orzo thoroughly in cold water. This prevents the pasta from becoming sticky. If you are packing this salad for a picnic, keep the feta cheese and parsley separate until just before serving to maintain their freshness and avoid wilting.

Always use freshly squeezed lemon juice for the dressing; bottled juice simply does not provide the same bright acidity needed for this refreshing salad.

When chopping your vegetables, aim for uniform, small dice so that every forkful gets a balanced bite of pasta and produce.

Variations & Substitutions

For added protein, consider adding 1 can (15 ounces) of rinsed and drained chickpeas or 1 cup of grilled, cubed chicken breast.

If you don’t have orzo, this recipe works wonderfully with acini de pepe, small pasta shells, or even farfalle (bow-tie pasta).

Swap out the feta cheese for goat cheese or dollops of fresh mozzarella pearls for a different creamy texture.

For a hint of sweetness, add 1/4 cup of dried cranberries or golden raisins to the mix.

Serving Suggestions

This hearty side dish pairs perfectly with grilled main courses, such as lemon herb salmon, grilled chicken skewers, or simple black bean burgers. It also makes an excellent, light lunch on its own, especially during warm weather.

Storage, Freezing & Reheating

Store leftover Rainbow Orzo Salad in an airtight container in the refrigerator. It tastes best within 3 days, as the vegetables will soften slightly over time. This salad is not recommended for freezing, as the creamy dressing and crisp vegetables do not freeze and thaw well.

FAQ

Can I make this salad ahead of time?

Yes, this salad is actually best made at least one hour ahead of time, or even the day before, to allow the orzo to fully absorb the delicious lemon dressing. Store it covered in the refrigerator.

My orzo is sticking together after chilling. How do I fix it?

Pasta tends to absorb residual dressing as it chills. To revive it, simply drizzle in an extra tablespoon of good olive oil and a small splash of fresh lemon juice, then toss well to separate the grains before serving.

Is this recipe gluten-free?

The standard recipe uses wheat-based orzo, so it is not gluten-free. To make it gluten-free, simply substitute the wheat orzo with a certified gluten-free orzo alternative, which is usually made from corn or rice blend.
