Gluten Free Italian Pasta Salad

Something about a cold pasta salad on a warm afternoon just hits differently, especially when nobody realizes it is gluten free until you tell them halfway through seconds.

I brought this to a neighborhood potluck last summer and watched three people go back for refills before the main course even made it to the table.

Ingredients

• Gluten-free fusilli or penne (300 g): Fusilli holds dressing in its spirals beautifully, but use whatever shape makes you happy.
• Cherry tomatoes, halved (1 cup): They burst just enough to sweeten the whole bowl.
• Cucumber, diced (1 cup): English cucumbers work best since you avoid the watery seed core.
• Red bell pepper, diced (1/2 cup): Adds a crunch that holds up even after chilling overnight.
• Red onion, finely chopped (1/4 cup): Soak it in cold water for five minutes if raw onion bite bothers you.
• Black olives, sliced (1/2 cup): Kalamata olives bring a briny punch that canned black olives simply cannot match.
• Sun-dried tomatoes, chopped (1/4 cup): These are the secret depth charges of flavor hidden throughout the salad.
• Mozzarella balls, halved (100 g): Optional, but the creamy pockets they create are worth every calorie.
• Grated Parmesan (1/4 cup): A light shower right before serving adds a salty finish.
• Extra virgin olive oil (4 tbsp): Use the good stuff here since it is the backbone of the dressing.
• Red wine vinegar (2 tbsp): Gives the dressing its bright, tangy personality.
• Dijon mustard (1 tsp): Acts as the emulsifier that keeps everything blended instead of separated.
• Garlic, minced (1 clove): One clove is enough because raw garlic can quickly overpower a cold dish.
• Dried Italian herbs (1 tsp): A blend of oregano and basil is all you need for that classic profile.
• Salt and black pepper: Season gradually and taste as you go.
• Fresh basil, chopped (2 tbsp): Add at the very end so it stays vibrant and fragrant.
• Fresh parsley, chopped (1 tbsp): A mild freshness that balances the stronger flavors.

Instructions

Cook the pasta right:

Boil the gluten-free pasta according to the package, then drain and rinse immediately with cold water so it stops cooking and does not turn mushy.

Build the salad base:

Toss the cooled pasta into a large mixing bowl with the cherry tomatoes, cucumber, bell pepper, red onion, black olives, and sun-dried tomatoes.

Add the cheese if using:

Gently fold in the halved mozzarella balls and a dusting of Parmesan, letting them tuck between the pasta folds.

Whisk the dressing:

In a small bowl, combine the olive oil, red wine vinegar, Dijon mustard, minced garlic, dried herbs, salt, and pepper until the mixture looks creamy and unified.

Coat everything:

Pour the dressing over the pasta and vegetables, then toss with a large spoon until every piece glistens.

Finish with fresh herbs:

Scatter the basil and parsley over the top and fold gently so the leaves do not bruise.

Chill and taste:

Refrigerate for at least fifteen minutes, then taste once more before serving because cold dulls seasoning.

Save to Pinterest

There is something quietly satisfying about watching a bowl of this disappear at a picnic while people ask for the recipe with tomato-stained fingers.

Making It Your Own

Toss in grilled chicken, chickpeas, or tuna if you want to turn this side into a full meal that satisfies even the hungriest guests at the table.

Keeping It Fresh

This salad holds beautifully in the fridge for up to two days, though the basil may darken slightly so save a few leaves for garnish if you are making it ahead.

Allergy Friendly Swaps

Skip the cheese entirely or use a plant-based alternative and the salad loses nothing in flavor. Always double-check your pasta packaging for cross-contamination warnings if serving someone with celiac disease.

• Check labels on sun-dried tomatoes since some pack in shared facilities.
• The Dijon mustard contains mustard allergens, so swap for a mustard-free option if needed.
• When in doubt, homemade dressing with just oil and vinegar is always safe.

Make it once and it will become the dish people expect you to bring everywhere, no questions asked.

Recipe Q&A

→ What pasta works best for this dish?

Choose gluten-free fusilli or penne; twisted or ridged shapes hold the dressing and bits of vegetables well. Cook to just al dente to avoid mushiness.

→ How do I prevent gluten-free pasta from becoming soft?

Salt the boiling water, follow the package timing closely, then drain and rinse under cold water to stop cooking. Rinsing also cools the pasta so it won’t absorb excess dressing.

→ Can I make this dairy-free?

Yes. Omit mozzarella and Parmesan or swap in plant-based cheese. Boost texture and flavor with extra olives, sun-dried tomatoes or a can of drained chickpeas.

→ What’s the best way to emulsify the dressing?

Whisk Dijon mustard into the vinegar first, then slowly stream in the olive oil while whisking vigorously to create a smooth vinaigrette that clings to the pasta.

→ How long will the salad keep in the fridge?

Stored in an airtight container it keeps up to 2 days. Add fresh basil and parsley just before serving to preserve brightness and texture.

→ How can I add more protein without changing flavors?

Add grilled chicken, flaked tuna, or drained chickpeas. Toss them in when the pasta is cool so they absorb the dressing without breaking down.
