My Personal Experience
I’ve always been a tuna salad fan, but once I switched to keto, I quickly realized the classic mayo-heavy version needed a makeover. The day I replaced mayo with mashed avocado, everything changed.
The texture became creamier.
The flavor became fresher.
The salad became lighter yet more satisfying.
The crunch from celery and onion made every bite bright and refreshing, and the healthy fats kept me full for hours. It became my go-to quick lunch — easy to mix, perfect for busy days, and ideal for meal prep. Trust me: once you try it, you’ll never go back to regular tuna salad again.

👉 Unlock Weekly Plans & Recipe BundlesHow to Make Keto Avocado Tuna Salad
1. Prepare the Tuna
Drain your canned tuna well.
Add it to a mixing bowl and break it apart with a fork.
2. Mash the Avocado
Add a ripe avocado to the same bowl.
Mash it to your preferred texture — smooth or chunky.
3. Add Lemon Juice
Squeeze fresh lemon juice over the mixture.
This adds brightness and slows avocado browning.
4. Add the Veggies
Mix in chopped red onion, celery, and bell pepper for crunch and freshness.
5. Season to Taste
Sprinkle with salt, pepper, and any extra seasonings you enjoy.
6. Serve and Enjoy
Enjoy immediately in:
• lettuce wraps
• cucumber bites
• over mixed greens
• stuffed inside avocado halves
• or simply by itself
Pro Tips for Perfect Results
✔ Choose ripe avocados
Soft but not mushy gives the perfect creaminess.
✔ Add heat for flavor
Jalapeños, chili flakes, or cayenne are great additions.
✔ Mix gently
You want the tuna to stay flaky, not fully mashed.
✔ Meal prep smart
Add lemon generously if storing longer to keep it green.

• Chopped almonds
• Diced radishes
• Cucumber cubes
For flavor:
