Shopping List

• Canned tuna: 2 cans (5 oz/140 g each), preferably tuna packed in water, drained well
• Mayonnaise: 3–4 tablespoons (use avocado oil or olive oil mayo for cleaner ingredients)
• Dijon mustard: 1 teaspoon
• Lemon juice: 1–2 teaspoons, fresh if possible
• Celery: 1–2 stalks, finely chopped
• Red onion or green onion: 2 tablespoons, finely chopped
• Dill pickles: 2 tablespoons, finely chopped (sugar-free)
• Fresh herbs: 1 tablespoon chopped dill or parsley
• Seasonings: Salt, black pepper, garlic powder (optional), and a pinch of paprika
• Optional add-ins: 1 hard-boiled egg (chopped), 1 tablespoon capers, 1 teaspoon hot sauce
• To serve: Butter lettuce leaves, cucumber slices, avocado halves, or low-carb crackers

How to Make It

1. Drain the tuna well. Press out excess liquid with the can lid or a fine mesh strainer.

   Drier tuna gives you a creamier, more flavorful salad.

2. Make the dressing. In a bowl, whisk together mayonnaise, Dijon, lemon juice, a pinch of salt, pepper, and paprika. Taste and adjust the acid or salt as needed.
3. Prep the mix-ins. Finely chop celery, onion, pickles, and herbs. Smaller pieces distribute better and give even crunch in every bite.
4. Combine. Add the drained tuna to the bowl with the dressing.

   Break it up with a fork, then fold in the celery, onion, pickles, and herbs. Stir gently until evenly coated.

5. Adjust texture. If it’s too dry, add another spoon of mayo or a splash of olive oil. If it’s too tangy, a pinch of salt or extra mayo helps balance it.
6. Optional add-ins. Fold in chopped hard-boiled egg for extra protein, capers for briny pop, or hot sauce for heat.
7. Chill briefly. Let it rest in the fridge for 10–15 minutes.

   Flavors meld and the texture improves.

8. Serve. Spoon into lettuce cups, on cucumber rounds, in an avocado half, or enjoy on its own.

How to Store

• Refrigerate: Store in an airtight container for up to 3 days.
• Keep it fresh: Add fresh herbs right before serving to maintain brightness.
• Avoid sogginess: If packing for lunch, keep lettuce or cucumbers separate until ready to eat.
• Do not freeze: Mayo-based salads don’t thaw well and can separate.

Why This is Good for You

• High protein, low carb: Tuna delivers lean protein that helps with fullness and muscle maintenance while keeping carbs minimal.
• Healthy fats: Mayo made with avocado or olive oil provides fats that support ketosis and satiety.
• Micronutrients: Tuna contains selenium and B vitamins, while celery, onions, and herbs add fiber and antioxidants.
• Steady energy: The protein-fat combo helps avoid blood sugar spikes and afternoon crashes.

Common Mistakes to Avoid

• Using tuna that’s too wet: Not draining well makes the salad watery and dilutes flavor.
• Overdoing sweet pickles: Regular sweet pickles or relish add hidden sugar. Choose sugar-free dill pickles.
• Too much mayo too soon: Start with less and add gradually until you hit the right creaminess.
• Skipping acid and salt: Lemon juice and a pinch of salt wake up the flavors and keep the salad from tasting flat.
• Letting it sit with lettuce: Assembled lettuce wraps can wilt. Store separately and assemble just before eating.

Variations You Can Try

• Avocado tuna salad: Swap half the mayo for mashed avocado for a creamy, nutrient-dense twist.
• Spicy chipotle: Stir in chipotle powder or adobo sauce, plus a squeeze of lime and chopped cilantro.
• Mediterranean style: Add olives, capers, cucumber, and a drizzle of extra-virgin olive oil.

  Season with oregano.

• Herb-forward: Load up on fresh dill, parsley, and chives. Add extra lemon zest for brightness.
• Egg lover’s: Fold in chopped hard-boiled eggs and a dash of smoked paprika for depth.
• Crunch booster: Add hemp hearts or chopped walnuts for texture and extra fats (watch portions for calories).

FAQ

Is canned tuna okay for a keto diet?

Yes. Canned tuna is very low in carbs and high in protein, making it a great staple for keto.

Choose tuna in water or olive oil with no added sugars.

How many carbs are in this tuna salad?

It depends on your exact ingredients, but a typical serving lands around 2–4 grams of net carbs. Keep pickles sugar-free and measure onions to keep carbs low.

Can I use Greek yogurt instead of mayo?

You can, but it’s less keto-friendly and less rich. If you want to lighten it up, try half mayo and half full-fat Greek yogurt for better flavor and texture.

What’s the best way to serve it without bread?

Lettuce wraps, cucumber slices, bell pepper boats, stuffed avocado halves, or on a bed of mixed greens all work well and keep carbs low.

How long does it last in the fridge?

About 3 days in a sealed container.

If it thickens, stir in a small splash of lemon juice or olive oil before serving.

Can I make it dairy-free?

Yes. Use a dairy-free mayonnaise and avoid yogurt or cheese add-ins. The base recipe is naturally dairy-free.

What if I don’t like raw onions?

Use green onions for a milder flavor, or soak chopped red onion in cold water for 5 minutes to take the edge off.
