Introduction
If you love simple, satisfying meals that are both quick to make and low in carbs, this tuna salad with celery and mayo is a go-to. The bright tang of lemon and Dijon balances rich mayonnaise while crisp celery provides crunch. It’s ideal for lunches, lettuce wraps, stuffed avocados, or a speedy keto snack. Below you’ll find a clear ingredients list, step-by-step directions, helpful variations, and detailed nutritional information (including carbs, fiber, sugar alcohols, and net carbs) for anyone following keto or low-carb diets.
Ingredients (serves 4)
- 12 oz (about 340 g) canned tuna in water, drained
- 1/2 cup (112 g) full-fat mayonnaise
- 1 cup (about 100 g) celery, finely diced (about 2 medium stalks)
- 2 tbsp red onion, finely minced (optional; about 20 g)
- 1 tbsp fresh lemon juice
- 1 tsp Dijon mustard
- 1 tbsp fresh parsley, chopped (optional)
- Salt and freshly ground black pepper, to taste
Optional low-carb add-ins:
- 1 small avocado, diced (adds creaminess; increases fat & calories)
- 1 tsp capers or 1 tbsp chopped dill pickles (use sugar-free pickles to keep carbs low)
- Pinch of smoked paprika or a few dashes of hot sauce
Directions
- Drain the tuna thoroughly and flake into a medium mixing bowl.
- Add the diced celery, minced red onion (if using), and chopped parsley.
- In a small bowl, whisk together the mayonnaise, lemon juice, and Dijon mustard. Taste and season with salt and pepper.
- Pour the dressing over the tuna mixture and stir until well combined. Adjust salt, pepper, or lemon to taste.
- Serve chilled or at room temperature. Suggestions: on a bed of mixed greens, in lettuce cups, stuffed into half an avocado, or with low-carb crackers.
Storage
- Refrigerate in an airtight container for up to 3 days. Stir before serving. Do not freeze (mayo-based salads don’t freeze well).
Keto & Low-Carb Tips
- Use full-fat, sugar-free mayonnaise to keep calories and fat high and carbs minimal.
- Avoid sweet relishes or store-bought dressings that contain added sugars.
- Add avocado or extra olive oil for more healthy fats without significant carbs.

Why this is keto-friendly
With roughly 1.3 g net carbs per serving and a high fat-to-protein ratio (when served with additional healthy fats like avocado), this tuna salad with celery and mayo fits well into most low-carb and ketogenic meal plans. The recipe avoids added sugars and starches; however, ingredient choices (for example, sweet pickle relish or low-fat mayo with added sugars) can raise carb counts, so check labels.
Variations & Serving Ideas
- Mediterranean: Add chopped olives, a squeeze of olive oil, lemon zest, and omit onion for a briny twist.
- Creamier: Fold in 1/4 mashed avocado for extra richness and potassium.
- Lighter (still low-carb): Replace half the mayo with plain full-fat Greek yogurt (adds some carbs; recalc nutrition if you swap).
- Spicy: Stir in a teaspoon of sriracha or a pinch of cayenne.
Conclusion
This zesty tuna salad with celery and mayo is fast, flavorful, and perfectly suited to low-carb and keto diets. It’s adaptable, easy to meal-prep, and delivers protein and healthy fats with minimal net carbs. Try it in lettuce wraps or stuffed into an avocado for a filling, low-carb lunch.
If you’d like, I can recalc these nutrition facts for different portion sizes, swap mayo for Greek yogurt, or convert the recipe to single-serve portions. Which would you prefer?
