• ¼ cup Fresh Basil, chopped – Bright, aromatic, and packed with flavor.

Step-by-Step Instructions

This low-carb tuna salad comes together in just a few easy steps:

1. Prep the Ingredients

Chop your red bell pepper, cucumber, green onions, cashews, and fresh basil. Drain your tuna thoroughly—excess liquid will make the salad watery.

2. Combine in a Bowl

In a large mixing bowl, combine the drained tuna with all your chopped ingredients.

3. Mix in Dressing

Add ½ cup of mayonnaise and the juice of one lemon. Stir until everything is evenly coated and creamy.

4. Season to Taste

Add salt and freshly cracked black pepper to your liking. Stir again.

5. Garnish and Serve

If you’d like, top with a sprinkle of extra fresh basil for a burst of color and flavor.

Tips for Making the Best Low Carb Tuna Salad

• Use high-quality tuna – Wild-caught, sustainably sourced tuna makes a noticeable difference in flavor.

• Fresh herbs matter – Fresh basil adds a bright pop that dried herbs just can’t replicate.

• Customize the crunch – Feel free to use sliced almonds or chopped walnuts if cashews aren’t available.

• Go light on the mayo – You can start with less mayo and add more gradually based on your preferred texture.

• Make it dairy-free – This recipe is naturally dairy-free, but double-check mayo labels if you’re sensitive to additives.

Creative Variations & Serving Suggestions

Swaps and Add-Ins

• Add avocado – Creamy, heart-healthy fats and a delicious texture boost.

• Spice it up – Add diced jalapeños or a pinch of cayenne for a kick.

• Use dill instead of basil – A more traditional tuna salad herb that works great here too.

• Swap cashews for sunflower seeds – Great for nut allergies and still offers crunch.

Serving Ideas

• Lettuce wraps – Spoon into butter or romaine lettuce leaves for a handheld lunch.

• Stuffed avocados – Fill avocado halves with tuna salad for an elegant low-carb meal.

• On cucumber rounds – Perfect for an appetizer or low-carb snack tray.

• In low-carb wraps or pita – Use almond flour or keto tortillas for something heartier.

How to Store Leftovers

This tuna salad is perfect for meal prep and will keep well for several days.

• Refrigerator Storage: Store in an airtight container for up to 3 days. Because of the mayo and lemon, it’s best consumed fresh.

• Freezing: Not recommended. The mayo and fresh vegetables don’t freeze well and may become watery or mushy after thawing.

Pro Tip:

If you plan to prep ahead for several days, chop and store the wet ingredients (like cucumber) separately and mix them in right before serving to maintain texture.

Frequently Asked Questions (FAQ)

Can I use Greek yogurt instead of mayo?

Yes! For a lighter version, plain full-fat Greek yogurt works well, though it will have a tangier flavor. It’s not strictly keto, but still low-carb.

What type of tuna is best?

Solid white albacore or chunk light tuna in water are both excellent choices. Tuna in oil will offer richer flavor but slightly more calories.

Is this recipe keto-friendly?

Absolutely. With minimal carbs and high-quality fats from mayo and cashews, it fits perfectly into a keto diet.

Can I make this nut-free?

Yes. Swap out the cashews for roasted sunflower seeds or omit them entirely if needed.

Is it safe for meal prep?

Yes, as long as you keep it well-refrigerated and eat within 3 days.
