No Mayo Mexican Tuna Salad Recipe

This Mexican tuna salad is creamy, tangy and prepared without any mayo. Loaded with fresh vegetables, black beans and dressed in a light Greek yogurt mixture, it’s a protein-rich lunch that’s ideal for meal prepping ahead.

I’m a big fan of putting together protein-based salads on weekends. It honestly cuts down on lunch stress during the week.

My regular rotation includes rotisserie chicken salad, cottage cheese egg salad and this Mexican tuna salad.

If you’ve tried my southwest dressing before, you’ll recognize the flavors here. The creamy, tangy taste comes from Greek yogurt paired with lime and salsa.

Why I Love This Mexican Tuna Salad

Zero cooking: Mix everything in a single bowl and you’re done in minutes.
Tons of serving options: Pile it on greens, serve alongside crackers, wrap it up, make a sandwich, or scoop it with tortilla chips. You could also use pita chips or almond flour crackers if you prefer.
Packed with protein: Tuna and black beans deliver 23 grams of protein per serving, keeping you satisfied long after lunch.
Great for batch cooking: Whip up a big batch and grab servings throughout the week for quick, ready-made lunches.

Ingredients Needed

tuna – I prefer canned tuna packed in water, drained thoroughly so it doesn’t make the salad soggy. Albacore is my go-to because the chunks are bigger and less mushy. The Wild Planet brand is excellent.
red bell pepper – brings a satisfying crunch and mild sweetness that rounds out the tangy dressing nicely.
jalapeño – totally optional, but it’s the way to go if you want some spice. Scoop out the seeds for a gentler kick, or grab jarred ones for convenience.
black beans – boost fiber content and make the salad heartier. Rinse and drain well to prevent excess liquid.
corn – brings sweetness and texture to the mix. Canned works great—just drain it first. Frozen corn is fine too; thaw and warm it before tossing it in.
red onion – delivers a sharp, punchy flavor. If you prefer something milder, soak it in cold water beforehand.
plain Greek yogurt – the star of the dressing, giving you creaminess without mayo. It adds protein and a subtle tang that pairs beautifully with the lime and salsa. Full-fat works best, though low-fat or nonfat both work fine.
fresh salsa – brings flavor and a little texture to the dressing. Pick a salsa you actually enjoy since it really shines here.
spices – cumin, chili powder and garlic powder create warmth and a subtle, smoky undertone.

How to Make Mexican Tuna Salad

Brittany’s Tips for the Best Tuna Salad

Drain the tuna completely: This matters more than you’d think. Any excess liquid dilutes the dressing and makes everything watery.
Choose a thick Greek yogurt: Thicker yogurt gives you that rich, creamy consistency. If yours is runny, strain it or cut back on the salsa.
Taste as you go: Depending on your salsa brand, you might need extra lime juice, salt or spice. Always do a quick taste test right before eating.
Chop everything small: Smaller pieces mean better distribution of flavors and a more pleasant texture in every bite.
Let it rest: Allowing the salad to sit for 10–15 minutes lets all the flavors meld together beautifully.

How to Store

I really appreciate having this in the fridge because it keeps well and takes the guesswork out of lunch. You can pull it straight from the container and have a meal ready without any fuss. Here’s what you need to know:

In the fridge: Keep it in a sealed container for 3–4 days.
When you’re ready to eat: Give it a good stir and add a squeeze of fresh lime if it needs brightening up. As it sits, the dressing may get a bit thicker, so this refreshes everything.

Frequently Asked Questions

How can I serve Mexican tuna salad?

Try it in lettuce cups, spooned over greens like my simple arugula salad, with crackers or stuffed into a wrap or sandwich on sourdough. It’s incredibly flexible and works great for quick meals or snacks.

What’s the best tuna to use for tuna salad?

Canned tuna in water is my preference—drain it well to avoid a watery salad. Albacore tuna is ideal because the pieces are larger and hold their texture better. Go with a brand you know you like since the flavor comes through clearly.

What can I use instead of Greek yogurt in Mexican tuna salad?

Mayo works great for a more classic approach, or try blending yogurt and mayo together for something in between. If you need dairy-free, mayo is your best option.

How do I keep Mexican tuna salad from getting watery?

Thoroughly drain your tuna, and make sure to rinse and drain the beans well too. A thicker yogurt also helps minimize excess moisture.

Is this Mexican tuna salad spicy?

There’s a gentle heat from the jalapeño and salsa, but you control the level. Skip the jalapeño entirely for a milder version, or load it up if you like things hot.
