Ingredients for Tuna Pasta Salad
Here’s everything you’ll need to make my favorite protein-packed lunch (and yes, I’ve tested every possible variation—these amounts are perfect):
- 2 cups cooked pasta – I like rotini or penne, but use whatever shape makes you happy (whole wheat works great for extra fiber)
- 1 can tuna in water – DRAINED well (about 5oz/142g – save the oil-packed kind for fancier recipes)
- 1/2 cup diced celery – Tiny cubes are key here for that satisfying crunch in every bite
- 1/4 cup diced red onion – Soak in cold water for 5 minutes if you’re sensitive to the sharpness
- 1/4 cup Greek yogurt – Plain, full-fat gives the creamiest texture (but nonfat works in a pinch)
- 1 tbsp lemon juice – Freshly squeezed makes all the difference, trust me
- 1 tsp Dijon mustard – The secret flavor booster (yellow mustard works in emergencies)
- Salt and pepper – To taste, but don’t skip it – bland tuna is the worst.
See? Nothing fancy – just simple ingredients that actually taste good together. The magic happens when they all get cozy in the fridge.
Equipment You’ll Need
Don’t worry—you probably already have everything you need. Here’s my no-fuss toolkit for making this tuna pasta salad:
- Medium pot – For cooking the pasta (obviously)
- Colander – To drain those noodles perfectly
- Mixing bowl – Big enough to toss everything without spilling
- Chef’s knife & cutting board – For dicing those crunchy veggies
- Measuring spoons – Only if you’re feeling precise (I usually eyeball it)
That’s it, No fancy gadgets required—just simple tools for a seriously easy lunch.
How to Make Tuna Pasta Salad
Okay, let’s get to the fun part—making this ridiculously easy tuna pasta salad. I’ve made this so many times I could do it in my sleep, but here’s exactly how I do it to get perfect results every single time.

Step 1: Cook and Cool the Pasta
First things first—get that pasta cooking. Boil it in salted water for 1 minute less than the package says (trust me, it’ll keep cooking slightly as it cools). Drain it in a colander and immediately rinse with cold water to stop the cooking process. I like to spread it out on a baking sheet to cool completely—this prevents that sad, mushy texture nobody wants in their salad.
Step 2: Prepare the Dressing
While the pasta cools, whisk together the Greek yogurt, lemon juice, and Dijon mustard in your mixing bowl. Go ahead and taste it—this is when I usually add an extra squeeze of lemon if it needs more zing. The dressing should be smooth and creamy with just a little tang from the mustard.
Step 3: Combine Ingredients
Now the fun part. Add your cooled pasta to the bowl with the dressing, then gently fold in the tuna, celery, and red onion. I use a rubber spatula for this to avoid breaking the pasta—those pretty spirals should stay intact. Be gentle but thorough—you want every bit coated in that creamy dressing.
Step 4: Chill Before Serving
Here’s my golden rule: don’t skip the chill time. Cover the bowl and pop it in the fridge for at least 30 minutes (I usually do an hour if I can). This lets all those flavors get to know each other properly. The dressing soaks into the pasta, the veggies get slightly softer, and the whole thing transforms from “ingredients in a bowl” to “magical lunch masterpiece.”
Tips for the Best Tuna Pasta Salad
After making this tuna pasta salad more times than I can count, I’ve picked up some foolproof tricks to make it absolutely perfect every single time:
- Go whole wheat: The nutty flavor and extra fiber make a world of difference (and it holds up better in the fridge)
- Drain that tuna well: Press it with the can lid to squeeze out every drop of water – soggy salad is the worst
- Chop veggies small: Tiny, even pieces mean you get a bit of everything in each forkful
- Season as you go: I always add a pinch of salt to the dressing AND the finished salad
- Make it ahead: The flavors actually get better after a night in the fridge – perfect for meal prep.
Oh, And here’s my favorite secret weapon: stir in a handful of chopped fresh dill right before serving if you want to feel fancy. Game changer.
Variations for Tuna Pasta Salad
The beauty of this recipe? You can twist it however you like. Here are my favorite ways to mix things up when I’m feeling adventurous (or just cleaning out the fridge):
- Crunch boost: Toss in diced cucumbers or bell peppers for extra freshness
- Creamy swap: Mash in avocado instead of yogurt for healthy fats (add extra lemon to keep it bright)
- Protein switch: Use chickpeas instead of tuna for a vegetarian version
- Herb it up: Fresh dill, parsley, or basil completely change the flavor game
See? One recipe, endless possibilities—just have fun with it.
Serving and Storing Tuna Pasta Salad
Here’s the best part about this tuna pasta salad—it actually gets better as it sits. I love packing it in my lunchbox with a handful of cherry tomatoes or some baby spinach on the side for a complete meal. If I’m feeling fancy, I’ll scoop it onto a bed of greens for a proper salad situation. Leftovers (if there are any) keep beautifully in an airtight container in the fridge for 3 days—just give it a quick stir before eating. Pro tip: If the dressing seems a little thick after chilling, splash in 1 tsp of water and mix well to bring it back to life.
Tuna Pasta Salad Nutrition
Now let’s talk numbers—but remember, these are just estimates (your exact amounts will vary based on brands and tweaks). One generous serving packs about 25g of protein from that powerhouse tuna, plus 5g of fiber if you use whole wheat pasta. At just 320 calories per cup, it’s the kind of lunch that keeps you full without weighing you down. Healthy eating never tasted so good.
Frequently Asked Questions
I get asked about this tuna pasta salad all the time—here are the questions that pop up most often (and my honest answers after years of making it weekly):
Can I use canned chicken instead of tuna?
Absolutely, Drain it well and flake it just like tuna—it makes a great alternative when you want to switch things up. My husband actually prefers it this way.
How long does tuna pasta salad last in the fridge?
It keeps beautifully for 3 days in an airtight container. The flavors actually improve after a day—just give it a good stir before eating. After day 3, the texture starts to change.
Can I make this dairy-free?
Yes, Swap the Greek yogurt for mashed avocado or a vegan mayo alternative. The texture will be slightly different, but still delicious.
What if I don’t have Dijon mustard?
Yellow mustard works in a pinch (use half the amount), or just skip it and add extra lemon juice for that tangy kick.
Can I freeze tuna pasta salad?
I don’t recommend it—the texture gets weird when thawed. This recipe is so quick, it’s better made fresh.
