I make this creamy tuna pasta salad on busy weeknights and for potlucks because it hits the sweet spot: simple, cool, and full of texture. Cold fusilli tossed with flaked tuna, crunchy cucumber and bell pepper, and a tangy yogurt-mayo dressing is exactly what you want when you need a no-fuss meal that travels well and feeds a crowd.
Why you’ll love this dish
This recipe is fast, budget-friendly, and flexible. It uses pantry staples—canned tuna and pasta—plus a handful of fresh veggies for crunch. The Greek yogurt lightens the dressing without sacrificing creaminess, so it feels fresher than a straight mayo-based salad. It’s ideal for weeknight dinners, picnic spreads, or a make-ahead lunch that tastes even better after a short chill.
“Perfectly creamy with bright cucumber and a hint of dill — my whole family asks for this on repeat.” — a regular weeknight favorite
If you enjoy creamy pasta salads, you might also like a tangy twist in my creamy tomato garlic pasta, which shares that same comfort-food vibe.
How this recipe comes together
Overview: cook the fusilli until just al dente, cool it quickly, then toss with a splash of rice wine vinegar and the seasonings so each piece stays separate. Fold in chopped cucumber, bell pepper, red onion, capers (if using), and flaked tuna. Whisk a simple dressing from Greek yogurt, light mayo, and fresh dill, then coat everything gently. Chill briefly to let flavors meld or serve right away for a brighter profile.
Key Ingredients
- 3 cups dried fusilli pasta (spirals hold the dressing well; use rotini or gemelli if you prefer)
- 14 ounces canned tuna, drained and flaked (preferably in water; drain thoroughly)
- ½ cup light mayonnaise
- ½ cup Greek yogurt (plain, full- or low-fat)
- 1½ cups cucumber, chopped (seed if watery)
- 1 cup red bell pepper, chopped
- ¼ cup red onion, finely chopped
- 1 tbsp rice wine vinegar
- 1 tbsp capers (optional) — or substitute chopped olives for briny flavor
- 1 tbsp fresh dill weed, chopped
- Garlic salt, black pepper, and red pepper flakes to taste
- Salt for cooking the pasta
Notes and substitutions: swap Greek yogurt for sour cream for a richer taste, or swap tuna for canned salmon or chickpeas for a vegetarian option. If you like herby cucumber salads, take inspiration from a similar chilled side like my creamy cucumber-dill salad.
Step-by-step instructions
- Fill a large pot with water and bring to a rolling boil. Salt it heavily so the pasta has flavor from the inside out.
- Add the fusilli and cook until al dente, about 8–11 minutes. Taste early — you want a bit of bite. Drain and rinse under cold water to stop cooking and cool quickly.
- While the pasta cooks, chop the cucumber, bell pepper, and red onion. Flake the drained tuna into a bowl with a fork.
- In a large mixing bowl, combine the cooled pasta with rice wine vinegar, a pinch of garlic salt, freshly ground black pepper, and a dash of red pepper flakes. Toss to coat — the vinegar helps prevent the pasta from clumping.
- Add the chopped vegetables, capers or olives, and flaked tuna. Fold gently so the tuna stays in pieces.
- In a separate small bowl, whisk together the Greek yogurt, light mayonnaise, and chopped dill until smooth. Pour this dressing over the pasta mixture. Fold everything together until evenly coated.
- Taste and adjust seasoning. Serve immediately for a crisp finish, or chill for 30–60 minutes to let flavors meld.
Best ways to enjoy it
This salad is versatile:
- Serve it as a light main with a wedge of lemon and extra dill on top.
- Bring it to a picnic alongside crusty bread and a green salad.
- Make it part of a buffet with roasted vegetables or grilled chicken.
- For a heartier meal, serve alongside a warm pasta like cowboy butter chicken pasta so guests can choose hot or cold.
Storage and reheating tips
- Refrigerate in an airtight container within two hours of serving.
- Keeps well for 3–4 days; the flavor improves after a few hours but the veggies stay crunchiest if eaten within 2 days.
- Freezing is not recommended: the texture of the mayo and yogurt changes when thawed.
- If leftovers seem dry, stir in a tablespoon of yogurt or a splash of milk and a squeeze of lemon before serving.
Helpful cooking tips
- Drain tuna very well: excess liquid will water down the dressing.
- Rinse pasta under cold water immediately after draining to stop residual cooking and to chill it for the salad.
- Adjust salt after combining — capers and canned tuna can add unexpected sodium.
- Use light mayonnaise plus Greek yogurt to keep creaminess with fewer calories. For richer flavor, swap for full-fat mayo.
- If you want the dressing brighter, add a teaspoon of Dijon mustard or an extra splash of rice wine vinegar. More ideas for creamy pasta techniques can be found in this creamy beef pasta recipe, which highlights emulsifying tips useful here.
Creative twists
- Add peas: fold in 1 cup of thawed frozen peas for sweetness and color (see a similar idea in creamy pesto chicken pasta for mixing proteins and peas).
- Mediterranean: swap dill for parsley, add chopped kalamata olives and feta instead of capers.
- Spicy kick: mix in sriracha or a pinch of smoked paprika.
- Lighter/vegan: replace mayo with vegan mayo and Greek yogurt with silken tofu blended until smooth; use chickpeas instead of tuna.
- Add crunch: top with toasted almonds or sunflower seeds just before serving.
Your questions answered
Q: Can I make this ahead for a party?
A: Yes. Make it up to a day ahead and chill. Wait to add delicate herbs or seeds until just before serving for best texture.
Q: How long will it keep in the fridge?
A: Store in an airtight container and eat within 3–4 days. Discard if it smells off or if you leave it unrefrigerated for more than 2 hours.
Q: Can I substitute whole wheat or gluten-free pasta?
A: Absolutely. Cook according to package directions and cool thoroughly. Gluten-free pasta can be stickier, so toss with the vinegar immediately to keep it separated.
Q: Is it safe to use tuna straight from the can?
A: Yes, canned tuna packed in water or oil is shelf-stable before opening. Once opened, drain and refrigerate any leftovers and use within a day or two.
Q: Why rinse the pasta with cold water?
A: Rinsing stops the cooking process, cools the pasta for a salad, and removes surface starch so the pieces remain separate instead of gluey.
