Quick & Colorful California Pasta Salad
California pasta salad is the answer when you need a side that feels as sunny as the state itself. Crisp bell peppers, cherry tomatoes, cucumber, and creamy avocado mingle with rotini in a lemony oregano dressing.

It comes together in about 25 minutes, and the veggies stay crunchy even on day two. This is the one I bring to every potluck.
Why This Salad Stays in the Fridge All Summer
The dressing is sharp and herby, not heavy, so the vegetables shine instead of getting lost. Every bite has a different pop of color and texture.
I also love that it gets better as it sits. The pasta soaks up the tang while the peppers and cucumber keep their snap. It’s just as welcome next to grilled chicken as it is scooped up on its own.
Ingredients

- 1 lb (450g) rotini pasta: or any short pasta like fusilli or penne
- 1 cup halved cherry tomatoes: about 5 oz, any color you like
- 1 yellow bell pepper, diced: orange or red work well too
- 1 small cucumber, seeded and diced: English or Persian cucumber, no need to peel
- 1/2 cup sliced black olives: drained
- 1/4 cup finely chopped red onion: soak in cold water 10 minutes for a milder bite
- 1/2 cup crumbled feta cheese: use a block and crumble it yourself for the best texture
- 1 ripe avocado, diced: add right before serving so it stays green
- 1/3 cup extra virgin olive oil: for the dressing
- 3 tbsp red wine vinegar:
- 1 tbsp fresh lemon juice:
- 1 tsp Dijon mustard:
- 1 garlic clove, minced:
- 1 tsp dried oregano:
- 1/2 tsp salt, plus more to taste
- 1/4 tsp black pepper:
Variations / Substitutions
- Make it a meal: Add 1 cup canned chickpeas (drained) or 1 cup diced cooked chicken.
- Switch the cheese: Cubes of mozzarella or crumbled queso fresco both work.
- Fresh herbs: Stir in 1/4 cup chopped fresh basil or parsley just before serving.
- Dairy-free: Omit the feta or use a plant-based alternative.

How to Make California Pasta Salad
Step 1: Boil the Pasta

Bring a large pot of salted water to a boil and cook the 1 lb rotini until al dente according to package directions, about 8 minutes. Right when the timer goes off, drain it in a colander and rinse well with cold water. That stops the cooking and washes off excess starch so the salad doesn’t get gummy.
Step 2: Whisk the Dressing

While the pasta boils, grab a small bowl and whisk together the 1/3 cup olive oil, 3 tbsp red wine vinegar, 1 tbsp lemon juice, 1 tsp Dijon, the minced garlic, oregano, 1/2 tsp salt, and 1/4 tsp black pepper. Keep whisking for a minute until the mixture looks emulsified and a little thicker. That’s your bright, tangy base.
Step 3: Chop the Vegetables

Dice the yellow bell pepper, cucumber, and red onion; halve the cherry tomatoes; slice the olives; and cube the feta. Keep the avocado separate for now. You can do this while the water heats and the pasta cooks, so the whole thing moves along quickly. Aim for bite-size pieces that are roughly the same width as the rotini spirals. That way every forkful has a little of everything.
Step 4: Toss the Salad

In a large mixing bowl, combine the cooled pasta with all the chopped veggies, olives, and feta. Pour the dressing over the top and toss gently with two big spoons until every piece is coated. The dressing will look a little loose right now, but the pasta soaks it in after a short rest.
Step 5: Chill and Serve

Cover the bowl and let the salad hang out in the fridge for at least 20 minutes, or up to overnight. When you’re ready to eat, fold in the diced avocado and give it a final toss. Taste and add a pinch more salt or a squeeze of lemon if it needs a lift, then pile it into a wide bowl or onto a platter. The colors look their best right then.
Tips for a Better Pasta Salad
- Rotini’s spirals grab dressing better than smooth pasta, so it’s worth using if you have it. Farfalle or penne still taste great though.
- If the salad seems dry after chilling, toss it with a tiny splash of olive oil and a squeeze of lemon to wake it back up.
- Add the feta and avocado right before serving for the freshest texture and color.
- Double the dressing and store the extra in a jar. It makes a quick green salad dressing later in the week.
To feed a larger crowd, here’s how to double everything.
| Ingredient | Single Batch | Double Batch |
|---|---|---|
| Rotini | 1 lb | 2 lb |
| Cherry tomatoes | 1 cup | 2 cups |
| Bell pepper | 1 | 2 |
| Cucumber | 1 small | 2 small |
| Black olives | 1/2 cup | 1 cup |
| Red onion | 1/4 cup | 1/2 cup |
| Feta | 1/2 cup | 1 cup |
| Avocado | 1 | 2 |
Storing Leftovers
Store leftover pasta salad in an airtight container in the fridge for up to 3 days. The avocado may brown a little, but it’s still tasty. For the brightest presentation, add fresh avocado when you serve it again.
What Goes Well With California Pasta Salad
It’s a natural next to grilled chicken thighs or a juicy turkey burger. For a vegetarian spread, pair it with black bean tacos or a pile of roasted portobellos.
Frequently Asked Questions
Can I make this pasta salad the day before?
Yes, you can prep it up to 24 hours ahead. Just hold the avocado and feta until right before serving.
What’s the best way to keep the avocado from turning brown?
Toss the diced avocado with an extra squeeze of lemon juice and fold it in at the last minute. The acid buys you a little more time.
Can I use a different type of pasta?
Absolutely. Any short shape like fusilli, farfalle, or penne works. Avoid long noodles like spaghetti. They don’t mix well with the chunky vegetables.
