Ingredients
Method
Cook and rinse pasta
- Cook the penne or rotini pasta according to package directions, then drain and rinse with cold water to cool it quickly.
Make the tzatziki
- Grate half the cucumber and squeeze out excess moisture, then mix it with Greek yogurt, sour cream, garlic, lemon juice, dill, salt, and pepper until smooth.
Assemble the salad
- Combine the pasta, remaining diced cucumber, cherry tomatoes, red onion, and Kalamata olives in a large bowl.
Coat with sauce
- Add the tzatziki sauce and toss until the pasta is evenly coated.
Finish
- Gently fold in feta cheese so it stays in small crumbles rather than fully melting into the dressing.
Chill
- Refrigerate the pasta salad for at least 1 hour before serving so flavors meld and the dressing thickens slightly.
Notes
For the best creamy-but-not-watery texture, squeeze the grated cucumber very well before mixing it into the yogurt base. Store covered in the refrigerator for 3 days; for best texture, add a fresh pinch of dill after chilling. Freezing is not recommended due to cucumber and yogurt texture. Vegetarian swap: keep feta or use a vegetarian feta alternative if needed; no other changes are required.
