Ingredients You’ll Need

For the orzo salad

1 1/2 cups uncooked orzo pasta
1 teaspoon salt
1 red bell pepper, finely chopped
1 orange bell pepper, finely chopped
1 English cucumber, finely chopped
1 small red onion, finely chopped
1 cup corn (fresh or frozen)
1/3 cup fresh basil, chopped
1/4 cup fresh parsley, chopped

For the lemon herb dressing

1/4 cup olive oil
3 tablespoon red wine vinegar
2 tablespoon lemon juice (about half a lemon)
2 tablespoon Dijon mustard
2 cloves garlic, minced
1 teaspoon dried oregano
1 teaspoon kosher salt
1/2 teaspoon ground black pepper

How to Make Rainbow Orzo Salad

Step 1: Cook the orzo

Bring a medium pot of water to a boil. Add the 1 teaspoon salt, then stir in the orzo.

Cook according to the package directions until tender (usually about 8–10 minutes). Give it a stir once or twice so it doesn’t stick together like it’s forming a pasta union.

Step 2: Drain and cool

Drain the orzo in a colander. Rinse briefly with cool water to stop the cooking and bring it down to salad temperature.

Let it drain really well—extra water can water down that dreamy dressing.

Step 3: Chop the veggies and herbs

While the orzo cooks (multitasking queen!), finely chop:

red bell pepper
orange bell pepper
cucumber
red onion

Then chop the basil and parsley. Pro tip: stack the basil leaves, roll them like a tiny green burrito, and slice thinly. Instant “fancy chef” energy.

Step 4: Prep the corn

If you’re using frozen corn, thaw it (a quick rinse under warm water works). If you’re using fresh corn, slice it off the cob. Either way, it adds sweet little pops that make the whole salad feel lively.

Step 5: Whisk the lemon herb dressing

In a small bowl or jar, add:

olive oil
red wine vinegar
lemon juice
Dijon mustard
minced garlic
oregano
kosher salt
black pepper

Whisk until smooth and creamy-looking, or shake in a jar like you’re auditioning for a salad dressing commercial.

Step 6: Toss it all together

In a large bowl, combine the drained orzo with the chopped veggies, corn, basil, and parsley.

Pour the dressing over the top and toss until everything is glossy and coated. Taste and adjust—more salt? a squeeze more lemon? You’re the boss of this bowl.

Step 7: Chill (optional, but lovely)

You can serve right away, but if you have 20–30 minutes to chill it, the flavors mingle and get even better. Kind of like a group chat that finally stops being awkward.

Mounia’s Tips for the Best Bowl Ever

Don’t skip draining well: Wet orzo = diluted dressing = sadness. Let it drip like it’s got nowhere to be.
Want a softer onion bite? Soak chopped red onion in cold water for 5–10 minutes, then drain. It keeps the flavor but calms the “wow, that’s onion” moment.
Make it a meal: Add chickpeas, diced grilled chicken, or feta if you want something more filling. (Also… feta and lemon dressing are best friends.)
If the dressing looks thick: Don’t panic. Dijon mustard does that. Once it hits the warm-ish pasta, it loosens up and turns silky. Extra comfort waiting to happen.

FAQs About Rainbow Orzo Salad

Can I make Rainbow Orzo Salad ahead of time?

Absolutely. This Rainbow Orzo Salad is great for meal prep. Store it in the fridge and give it a quick toss before serving. If it seems a bit dry the next day, add a tiny splash of olive oil or a squeeze of lemon.

How long will it last in the fridge?

Usually 3–4 days in an airtight container. The veggies stay crisp, and the flavors get even more delicious.

Can I use a different pasta instead of orzo?

Yes! Small pastas like ditalini, small shells, or couscous-style pasta work well. Orzo just gives that perfect “bite” while still feeling light.

I don’t have fresh basil—what can I do?

You can use more parsley, or swap in another fresh herb you like (dill is amazing here). If you only have dried basil, use it sparingly—fresh is best, but we work with what we’ve got.

Can I use bottled lemon juice?

You can, but fresh lemon juice gives the dressing a brighter flavor. If your lemon looks sad and dry, roll it on the counter first—little trick, big payoff.
