Healthy Tuna Salad Recipe

Why This Tuna Salad Works

Traditional tuna salad drowns protein-rich tuna in mayonnaise, adding unnecessary calories and fat. This healthier version uses half the mayo and replaces it with protein-packed Greek yogurt, cutting calories by 40% while boosting protein and probiotics.

The result is a creamy, satisfying lunch that delivers 27g protein per serving—perfect for muscle maintenance, satiety, and meal prep. Crunchy vegetables add fiber and texture, while fresh herbs and lemon juice brighten the flavors.

Tuna salad is one of the easiest high-protein meals to prep on Sunday and enjoy all week. It takes 10 minutes to make and pairs with endless serving options from salads to sandwiches to lettuce wraps.

Complete Ingredient Breakdown

Protein Base

3 cans (5 oz each) tuna packed in water, drained Wild-caught tuna is ideal for omega-3 fatty acids and lower mercury levels. Skipjack (light tuna) contains less mercury than albacore (white tuna). Always choose water-packed over oil-packed to control fat content.

Creamy Components

1/2 cup plain Greek yogurt (full-fat or 2%) Replaces half the mayo while adding 10g protein and probiotics for gut health. Greek yogurt’s tangy flavor complements tuna perfectly. Use plain, not flavored, to avoid added sugar.

2 tablespoons olive oil mayonnaise A small amount of mayo adds richness and traditional tuna salad flavor. Choose olive oil or avocado oil mayo for healthier fats. You can reduce to 1 tablespoon if desired.

Crunchy Vegetables

1/3 cup finely diced celery Provides satisfying crunch and subtle flavor without many calories. Finely dice for even distribution throughout the salad.

1/4 cup finely diced red onion Adds sharp, fresh flavor. Red onion is milder than white or yellow. Soak in cold water for 10 minutes if you prefer less bite.

2 tablespoons chopped dill pickles Briny pickles add tang and moisture. You can substitute sweet pickles, capers, or skip them entirely.

Flavor Boosters

1 tablespoon fresh lemon juice Brightens all flavors and prevents the salad from tasting heavy. Fresh lemon is always better than bottled.

1 tablespoon fresh dill (or 1 teaspoon dried) Classic pairing with tuna. Parsley, chives, or basil work too.

Salt and black pepper to taste Start with 1/4 teaspoon salt and 1/8 teaspoon pepper, then adjust. Pickles add salt, so taste before adding more.

Step-by-Step Instructions

Preparation (10 minutes total)

1. Drain tuna thoroughly: Press with a fork or paper towel to remove excess water. Watery tuna makes soggy salad.

2. Mix creamy base: In a medium bowl, combine Greek yogurt, mayonnaise, and lemon juice. Whisk until smooth and well combined.

3. Add tuna: Flake tuna into the yogurt mixture. Break up large chunks but don’t overmix—you want some texture.

4. Fold in vegetables: Add celery, red onion, and pickles. Fold gently to distribute evenly.

5. Season: Add fresh dill, salt, and pepper. Taste and adjust seasonings. Tuna salad should be well-seasoned since it’s often served cold, which mutes flavors.

6. Chill: Refrigerate for at least 30 minutes before serving. This allows flavors to meld and the salad to firm up.

Meal Prep Tips

Tuna salad is one of the easiest proteins to meal prep:

Preparation Strategy:

1. Make a full batch on Sunday
2. Portion into 4 containers
3. Pack vegetables (lettuce, crackers, etc.) separately to prevent sogginess
4. Add lemon wedge to each container for brightening before eating

Storage Guidelines:

• Refrigerate in airtight containers for up to 3 days
• Store separately from bread, crackers, or greens
• Keep an ice pack in your lunch bag if eating after 4+ hours

Portion Control:

• 1/2 cup tuna salad = 1 serving = 27g protein
• Pair with vegetables and whole grains for a complete meal
• Pack with carrot sticks, apple slices, or a small salad

Store using methods from Best Meal Prep Containers to keep tuna salad fresh all week.

Nutritional Benefits

Each serving provides:

• 250 calories: Reasonable for a protein-rich lunch component
• 27g protein: Excellent for muscle maintenance and satiety
• 6g carbs: Low-carb friendly
• 13g fat: Mostly healthy fats from olive oil and tuna
• Omega-3 fatty acids: Anti-inflammatory, heart-healthy
• Vitamin D: Naturally occurring in tuna
• Selenium: Antioxidant mineral

Compare this to restaurant tuna salad (400+ calories, 30g+ fat) and you can see the dramatic improvement.

Choosing Quality Tuna

Not all canned tuna is created equal. Here’s what to look for:

Best Options:

• Wild-caught skipjack (light tuna): Lower mercury, sustainable
• Pole-and-line caught: Most sustainable fishing method
• Packed in water: Controls fat and calorie content
• BPA-free cans: Reduces chemical exposure

Mercury Considerations:

• Skipjack/light tuna: Lower mercury, safe for 2-3 servings per week
• Albacore/white tuna: Higher mercury, limit to 1 serving per week
• Pregnant women should consult their doctor about safe tuna consumption

Brands to Consider: Look for sustainable certifications (MSC, Friend of the Sea) and low mercury testing.

Making It Dairy-Free

For a dairy-free version, replace Greek yogurt with:

Mashed avocado (1/2 cup): Adds healthy fats and creamy texture Dairy-free yogurt (1/2 cup): Coconut or almond-based yogurts work well Tahini (3 tablespoons): Sesame paste adds richness and healthy fats Hummus (1/3 cup): Adds protein and Mediterranean flair

You can also use all mayo (1/3 cup total) if you prefer traditional tuna salad texture.

Common Mistakes to Avoid

1. Not draining tuna well enough Watery tuna makes watery salad. Press tuna firmly with a fork or paper towel to remove excess liquid.

2. Over-mixing Vigorous mixing breaks down tuna into paste. Fold gently to maintain some texture and chunks.

3. Under-seasoning Cold foods need more seasoning than hot foods. Taste and adjust salt, pepper, and lemon juice generously.

4. Storing improperly Don’t assemble sandwiches ahead—bread gets soggy. Store tuna salad separately and assemble just before eating.

5. Using low-quality tuna Oil-packed tuna in cheap brands can taste fishy. Invest in quality water-packed wild-caught tuna for best flavor.

FAQs

How long does tuna salad keep? Store in an airtight container in the refrigerator for up to 3 days. After that, texture and flavor decline. Never leave tuna salad at room temperature for more than 2 hours due to mayonnaise and seafood food safety concerns.

Can I make this dairy-free? Yes. Swap Greek yogurt for mashed avocado (use half a ripe avocado), dairy-free yogurt (coconut or almond-based), or tahini (3 tablespoons). You can also use all mayonnaise (1/3 cup total) for a traditional dairy-free tuna salad.

What type of tuna is healthiest? Wild-caught skipjack (light tuna) packed in water has the best omega-3 fatty acid profile and lowest mercury levels. It’s also more sustainable than other tuna varieties. Look for pole-and-line caught tuna with MSC or Friend of the Sea certifications for the most responsible choice.

Can I freeze tuna salad? Not recommended. Mayonnaise and Greek yogurt don’t freeze well—they separate and become watery when thawed, resulting in an unappealing texture. Tuna salad is best made fresh or stored refrigerated for up to 3 days. If you need to prep ahead, freeze the drained tuna separately and make the salad fresh when ready to eat.
