Key Ingredients Explained
Good tuna salad balances creamy, crunchy, and bright elements. Skip any and the flavor drops.
- Tuna (canned in water or olive oil): The base. Use chunk light for softness or albacore for firm texture.
- Mayonnaise (sugar-free): The creamy binder; check labels to avoid hidden sugars.
- Avocado: Adds healthy fats and fresh creaminess that elevates the salad.
- Celery and red onion: Provide crunch and zing to wake up the flavors.
- Fresh dill and lemon juice: Dill adds deli-style flavor; lemon brightens and lightens.
- Romaine or butter lettuce: Romaine offers sturdy crunch; butter lettuce is soft and flexible. Choose leaves that won’t tear easily.
Tips for Success
- Choose sturdy lettuce like romaine or butter lettuce.
- Drain tuna thoroughly to prevent watery salad.
- Season well with salt, pepper, and lemon juice, tasting as you go.
- Boost flavor with add-ins like capers, pickles, olives, garlic powder, hot sauce, or Dijon mustard for an extra kick.
Meal Prep & Storage
Perfect for prepping in advance if you keep components separate.
- Store tuna salad airtight for up to 3 days.
- Keep lettuce leaves washed, dried, and wrapped in paper towels in the fridge.
- Serve cold; reheating isn’t recommended.
Serving Suggestions
- Lunch or dinner: Enjoy with cucumber slices, simple salad, or cherry tomatoes if keto-friendly for you.
- Snack or appetizer: Use mini lettuce cups for bite-sized wraps.
- On-the-go: Pack ingredients separately and assemble before eating to avoid soggy leaves.

Instructions

- Stir in the celery, red onion, dill, lemon juice, garlic powder, salt, and pepper until everything is evenly combined and taste, adjusting seasoning with more salt, pepper, or lemon juice as needed.
- If using optional keto add-ins like pickles, capers, Dijon mustard, or hot sauce, fold them into the tuna salad until just combined.
- Lay the romaine or butter lettuce leaves on a plate or tray and pat dry again if they look damp so the filling adheres well.
- Spoon the tuna salad evenly into the center of each lettuce leaf, dividing it among about eight leaves to make four generous wraps or more smaller wraps as desired.
