Why You'll Love This Recipe
About the Ingredients
8 oz (225g) rotini pasta
Use any short pasta like fusilli or penne. For a gluten-free option, choose your favorite GF pasta.
1 cup (150g) cherry tomatoes, halved
Grape tomatoes also work great. For best flavor, use ripe, in-season tomatoes.
1 cup (100g) cucumber, diced
English cucumber has fewer seeds, but regular cucumber works too. Leave the skin on for extra crunch.
1/2 cup (75g) red bell pepper, chopped
Any color bell pepper works. Buy firm peppers with glossy skin for the best texture.
1/4 cup (40g) red onion, finely chopped
Soak chopped red onion in cold water for 10 minutes to mellow its bite if desired.
1/4 cup (30g) grated Parmesan cheese
Freshly grated parmesan melts better and has more flavor. For a dairy-free version, use nutritional yeast.
1/4 cup (60ml) extra virgin olive oil
Use a good quality olive oil for the best flavor. You can substitute with avocado oil.
2 tablespoons (30ml) fresh lemon juice
Fresh lemon juice is key – bottled won't give the same bright taste. Roll the lemon on the counter before juicing for more juice.
1 teaspoon Dijon mustard
Dijon helps emulsify the dressing. Yellow mustard can be used in a pinch, but Dijon is milder.
1 clove garlic, minced
Use fresh garlic for the best pungent flavor. You can add more or less to taste.
1 teaspoon dried oregano
Dried oregano works well here. If using fresh, use 1 tablespoon chopped.
Salt and freshly ground black pepper, to taste
Season generously. Kosher salt is great; freshly ground pepper adds a nice kick.
Tips & Tricks
- Salt your pasta water generously – it should taste like the sea. This is the only chance to season the pasta from within.
- Don't overcook the pasta – cook until al dente (firm to the bite). It will soften slightly as it absorbs the dressing.
- Rinse the pasta under cold water immediately after draining to stop the cooking and cool it down quickly for the salad.
Pro Tips
Step-by-Step Instructions
1. Cook the Pasta
Bring a large pot of salted water to a rolling boil (212°F / 100°C). Add the rotini and cook according to package directions until al dente, usually 8-10 minutes. Stir occasionally to prevent sticking.
2. Drain and Rinse
Drain the pasta in a colander and immediately rinse under cold running water to stop the cooking process. Shake well to remove excess water.
3. Prep the Vegetables
While the pasta cooks, halve the cherry tomatoes, dice the cucumber, chop the bell pepper, and finely chop the red onion. Place them in a large mixing bowl.
4. Make the Vinaigrette
In a small bowl or jar, whisk together the olive oil, lemon juice, Dijon mustard, minced garlic, oregano, salt, and pepper. Shake or whisk until well combined and slightly emulsified.
5. Combine Everything
Add the cooled pasta to the bowl with the vegetables. Pour the vinaigrette over the top and toss gently to coat everything evenly.
6. Add Parmesan
Sprinkle the grated Parmesan over the salad and toss once more. Taste and adjust seasoning with additional salt, pepper, or lemon juice if desired.
7. Chill and Serve
Cover the bowl and refrigerate for at least 30 minutes to allow the flavors to meld. Serve chilled, garnished with extra Parmesan or fresh herbs if you like.
Delicious Variations
- Add 1 cup (150g) of cooked, cubed chicken breast for a heartier meal.
- Swap the veggies for artichoke hearts, sun-dried tomatoes, and olives for a Mediterranean twist.
- Use fresh basil instead of oregano and add 1/2 cup of fresh mozzarella pearls for a Caprese-style salad.
How to Store Cold Pasta Salad with Lemon Herb Vinaigrette

Frequently Asked Questions
Q: How long does cold pasta salad last in the fridge?
Cold pasta salad lasts up to 4 days in the refrigerator when stored in an airtight container. After that, the vegetables may become soggy and the pasta may break down.
Q: Can I make cold pasta salad ahead of time?
Yes, you can make it up to 24 hours in advance. In fact, it tastes even better the next day as the flavors have time to meld. Just give it a good stir before serving.
Q: What can I add to cold pasta salad for protein?
Grilled chicken, shrimp, tuna, chickpeas, or white beans are excellent additions. Add them just before serving to keep them from getting soggy.
Q: How do I prevent pasta salad from being dry?
Make sure to dress the salad with enough vinaigrette and, if storing, add a splash of olive oil or lemon juice before serving. Also, don't over-rinse the pasta – a little starch helps the dressing cling.
