This easy tzatziki pasta salad brings together crisp veggies and tender rotini tossed in a creamy herbed yogurt dressing that just sings with lemon and garlic. I make this dish every time I am asked to bring a side to potlucks or summer barbecues because it is reliably refreshing and a total crowd pleaser.
The first time I brought this to my neighbor’s BBQ it disappeared within minutes and I had people asking for the recipe before dessert even hit the table. It really is that good and perfect for sharing.

- Sweet onion: Gives a subtle bite that blends well into the salad Opt for a fresh onion with no sprouting
- Bell pepper: Offers a splash of color and sweetness You can use regular or roasted from a jar
- Kalamata olives: Lend a bit of salty depth Go for pitted olives for convenience

- Plain Greek yogurt: Forms the creamy base Opt for full fat for a rich mouthfeel or dairy free if needed

Step-by-Step Instructions
- Cook the Pasta:
- Fill a large pot with water and bring to a boil over high heat Add the rotini and a generous pinch of salt Stir frequently and cook until the noodles are just al dente Check early to avoid mushy pasta Once ready drain thoroughly then spread on a baking sheet to cool so they do not stick together
- Chop and Prepare Vegetables:
- While the pasta cools prep the cucumber carrot onion bell pepper and olives Dice every veg into even pieces about the size of the pasta for a consistent bite Ensure there are no seeds or extra moisture left
- Make Tzatziki Dressing:
- Measure the Greek yogurt red wine vinegar lemon juice minced garlic onion powder oregano and dill into a mason jar or lidded container Secure the lid and shake until the mixture is completely smooth and creamy Taste and add a splash of water if needed so the dressing will toss easily
- Mix the Salad:
- In a very large bowl combine the cooled pasta chopped vegetables olives and fresh parsley Pour the dressing over everything then use two big spoons or clean hands to toss thoroughly Coat every ingredient well and gently so nothing gets mushy
- Chill and Serve:
- Cover the salad and chill it for at least one hour in the refrigerator This not only melds flavors but helps the dressing thicken slightly Stir again before serving and taste for salt If needed add an extra squeeze of lemon or sprinkle more herbs just before serving

I always look forward to using my own backyard parsley in this recipe because its bright flavor beats anything I get at the store. One time we made this salad picnic style at the beach and by the end of the day not a single rotini was left in the bowl. Tzatziki instantly tastes like summer to me.
Storage Tips
Store leftover pasta salad in an airtight container in the fridge It stays fresh for up to three days If it seems a bit dry after storage just stir in a spoonful of yogurt or a drizzle of olive oil before serving
Ingredient Substitutions
Swap out rotini for penne or bow ties if you like Replace Greek yogurt with your favorite dairy free alternative to make it vegan If you do not have fresh dill use a bit of dried but rub it between your fingers to release the aroma You can leave out olives if they are not your thing or sub in capers for a similar briny touch
