Ingredients for beet tuna salad
Roasted beets and flaky tuna create a vibrant, protein-packed salad with perfect texture contrast.
| Ingredient | Amount | Notes |
|---|---|---|
| Medium Beets 🍠 | 2 whole | Roasted or boiled, peeled and chopped |
| Canned Tuna in Water 🐟 | 2 cans | High-quality, drained well |
| Red Wine Vinegar 🍷 | ½ cup | For tangy brightness |
| Extra-Virgin Olive Oil 🫒 | ½ cup | For richness and smoothness |
| Dijon Mustard 🍯 | 1 tbsp | For depth of flavor |
| Honey 🍯 | 1 tbsp | Balances acidity (sub maple syrup) |
| Fresh Dill 🌿 | ¼ cup | Chopped, for freshness |
| Fresh Lemon Juice 🍋 | 1 tbsp | Brightens the dressing |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |
| Mixed Greens 🥬 | 4 cups | Optional for serving |
| Toasted Walnuts 🥜 | ½ cup | Optional for crunch |
The beets are the star here—roasting them brings out their natural sweetness and deep color. Pre-cooked vacuum-packed beets from the grocery store save time, but roasting your own (wrap whole beets in foil, bake at 400°F for 45-60 mins) gives the best flavor. Look for beets with smooth, vibrant skin—they’ll stay fresher longer. For the tuna, high-quality brands like Wild Planet or StarKist make a huge difference in texture and taste. Drain it well to avoid a watery salad, and flake it gently with your fingers for that perfect chunky texture.
No red wine vinegar? Apple cider vinegar or lemon juice works just as well—just add a pinch more honey to balance. Fresh dill is ideal, but dried dill at half the amount gets you close. The honey can be swapped for maple syrup if you prefer, though it’ll have a slightly different flavor profile. For extra texture, toast the walnuts in a dry pan for 3-4 minutes until fragrant—Trader Joe's or Costco sell them pre-toasted, which is a great shortcut. If you’re feeling adventurous, add a pinch of smoked paprika to the dressing for a subtle depth.
This salad keeps beautifully in the fridge for 3 days if stored in an airtight container. The dressing can be made ahead and stored separately for up to 5 days. For serving, toss everything together right before eating so the greens stay crisp. If you’re prepping for a crowd, portion the dressing separately and let everyone customize their bowl—some like it tangy, others prefer it sweeter. The roasted beets can also be stored peeled and chopped in the fridge for 4 days, covered with a damp paper towel.
Why You'll Love This Recipe
- Minimal Chopping Required: I swear by this—just roast whole beets (foil packet, 400°F for 45 mins) while you drain the tuna. No peeling, no dicing, no mess. The vinegar and mustard dressing comes together in three swirls of a fork. Honestly, it’s the kind of recipe that makes me question why I ever stressed over complicated salads.
- Earthy-Meets-Bright Magic: That deep, sweet beet flavor? It cuts through the tuna’s richness like a knife through butter. The red wine vinegar adds a tangy lift, while the Dijon mustard ties everything together—savory, slightly sharp, and ridiculously balanced. It’s the kind of flavor combo that makes you go, “Wait, why haven’t I done this before?”
- Lunchbox Superstar: Between us, this is my go-to for packed lunches—holds up for days, no sad wilted greens here. Use it in wraps for a quick office meal, smear it on crackers for a fancy charcuterie bite, or pile it into a pita with greens for a no-fuss dinner. (Yes, even on a Tuesday night.)
- Pantry Stash Hero: Canned tuna, roasted beets, olive oil—this salad costs me about $5 for four servings. The beets keep for weeks in the fridge, and the dressing lasts forever. I make a big batch on Sundays, and by Wednesday, I’m still eating it because it’s that good. Budget-friendly? More like budget genius.
Step-by-step instructions for beet tuna salad recipe
This twist on classic tuna salad delivers bold flavors and vibrant color—let's make it together.
Roast or Boil the Beets Until Tender
Preheat your oven to 400°F and wrap the 2 whole medium beets tightly in aluminum foil. Roast for 45-60 minutes until fork-tender. You'll know they're done when the beet pierces easily and the skin slips off smoothly.
Alternatively, boil the beets whole in salted water for 25-30 minutes until soft. I prefer roasting because it caramelizes the natural sugars, giving deeper flavor. Let the beets cool slightly before peeling and chopping them into ½-inch cubes—this size ensures they hold their shape but still blend well with the tuna.
Prepare the Dressing Components
In a medium bowl, whisk together the 0.5 cup red wine vinegar, 0.5 cup extra-virgin olive oil, 1 tablespoon Dijon mustard, and 1 tablespoon honey until fully combined. The mixture should look emulsified but not overly thick. If it separates, whisk vigorously for another 10 seconds—the acidity from the vinegar and sweetness from the honey will come together beautifully.
Add the 1 tablespoon fresh lemon juice, 0.5 teaspoon salt, and 0.25 teaspoon black pepper to the dressing. Taste and adjust seasoning—you might need a touch more salt or lemon to balance the sweetness. This dressing is the heart of the salad, so don't rush this step. The flavors should be bright, tangy, and well-rounded.
Combine Beets, Tuna, and Dressing
Drain the 2 cans canned tuna in water thoroughly, pressing gently on the flakes with a paper towel to remove excess moisture. In a large mixing bowl, combine the tuna, chopped beets, and the prepared dressing. Using a fork, gently fold everything together until the beets and tuna are evenly coated. Be careful not to overmix—just enough to combine so the beets stay intact and the tuna stays flaky.
Stir in the 0.25 cup chopped fresh dill at the end. The dill adds a fresh, herby brightness that cuts through the richness of the tuna and sweetness of the beets. Give it one final taste and adjust seasoning if needed—this is your chance to make it perfect for your palate.
Assemble and Serve
Divide the 4 cups mixed greens evenly among serving plates. Spoon the beet tuna salad over the greens, creating a colorful, earthy base. For extra crunch and texture, sprinkle the 0.5 cup toasted walnuts on top just before serving. The walnuts add a satisfying contrast to the creamy tuna and tender beets.
This salad keeps well in the refrigerator for up to 2 days, though I recommend eating it fresh for the best texture. Serve immediately for a refreshing, nutrient-packed meal that's perfect for lunch or a light dinner. The combination of sweet beets, rich tuna, and bright dressing creates a flavor profile that's both unexpected and utterly delicious.
Pro Tips For Making Beet Tuna Salad
- ROAST BEETS UNTIL TENDER: Cook them at 400°F (200°C) for 45-50 minutes—pierce first with a fork, then wrap in foil after 30 minutes. I learned this the hard way: undercooked beets taste mealy, and overcooked ones turn to mush. The foil traps steam, giving you that perfect creamy texture without drying them out.
- DRAIN AND PRESS TUNA DRY: Drain the tuna in a fine-mesh strainer, then press out excess water with a paper towel. Wet tuna makes the salad soggy, and no one wants a watery tuna-beet mash. This step takes 30 seconds but makes a real difference in texture.
- WHISK VINEGAR AND OIL FIRST: Mix the red wine vinegar and olive oil in a small bowl before adding mustard—this emulsifies them instantly. I used to toss everything together at once, and the dressing always separated. A quick whisk ensures a smooth, cohesive dressing every time.
- ADD MUSTARD LAST, THEN MIX GENTLY: Spoon the Dijon into the tuna-beet mix and fold in with a rubber spatula—don’t stir vigorously. Mustard burns easy, and aggressive mixing turns the salad into a paste. A light hand keeps the flavors bright and the texture intact.
Flavor customization for this dish
Sweet & Tangy Twist
Boost the dressing by adding 1 teaspoon orange zest and 1 tablespoon orange juice to the red wine vinegar base. The citrus brightens the earthy beets and balances the richness of the tuna beautifully.
I also like adding ½ teaspoon grated ginger for a subtle kick that pairs perfectly with the honey and Dijon. 🍊
Spicy Kick Option
For heat lovers, stir in ½ teaspoon smoked paprika and ¼ teaspoon cayenne pepper to the dressing. The smokiness complements the roasted beets, while the cayenne adds a slow-building heat.
If you prefer a milder spice, swap the cayenne for 1 teaspoon hot honey—it’s sweet with a gentle burn. Trust me, this takes the salad to another level.
Herb Variations
Swap out the dill for chopped parsley and tarragon for a French-inspired twist, or use fresh cilantro and lime juice for a zesty, Mexican-inspired flavor. I’ve also tried adding thinly sliced scallions at the end for a fresh crunch. Each herb brings a unique brightness that elevates the dish.
Creamy Upgrade
For a richer texture, stir in 2 tablespoons Greek yogurt or 1 tablespoon crumbled feta cheese after combining the beets and tuna. The creaminess balances the tangy dressing and adds a luxurious mouthfeel. If you’re feeling adventurous, add ¼ cup avocado chunks for extra creaminess and healthy fats.
Crunchy Add-Ins
Beyond walnuts, try toasted pecans for a buttery crunch or crispy fried shallots for a savory punch. For something lighter, add thinly sliced cucumber or radishes to cut through the richness. These add-ins keep the salad fresh and exciting—perfect for warm days. 🥜
Umami Boost
Add depth with 1 teaspoon soy sauce or tamari to the dressing for an umami-rich flavor that pairs perfectly with the tuna. Alternatively, stir in 1 tablespoon miso paste for a deeper, fermented taste. Both options add complexity that makes the salad feel more restaurant-worthy.

Frequently asked questions
Can I use canned beets instead of fresh?
Yes! Canned beets work perfectly—just drain and rinse them well to remove excess liquid. They’re pre-cooked and ready to chop, saving you 45 minutes of roasting time. For best results, pat them dry with a paper towel before mixing with the tuna to prevent a watery salad.
How do I keep the tuna from getting soggy?
Press the drained tuna flakes gently with a paper towel to remove all moisture before mixing. Also, add the dressing just before serving or store it separately in the fridge. If prepping ahead, keep the beets and tuna separate until ready to toss—this preserves the texture for up to 2 days.
Is this salad spicy or mild?
The base recipe is mild and balanced, with a tangy-sweet dressing. For heat, add ¼ teaspoon cayenne or ½ teaspoon smoked paprika to the dressing. If you prefer no spice, skip it entirely—the natural flavors shine without it.
Can I make this gluten-free?
This recipe is naturally gluten-free as long as you use gluten-free Dijon mustard. Check labels on all ingredients, especially the tuna and vinegar. The honey and olive oil are also typically safe, but always verify for cross-contamination if needed.
What’s the best way to store leftovers?
Store in an airtight container with the dressing sealed separately. Keep the salad in the fridge for up to 3 days, and the dressing for 5 days. When ready to eat, toss everything together—this preserves the crispness of the beets and flakiness of the tuna.
