Ingredients You’ll Need

Here’s your shopping list without the fluff:

• Canned tuna in water or oil
• Mayonnaise
• Dijon mustard
• Lemon juice
• Garlic powder
• Onion powder
• Crushed black pepper
• Salt
• Chopped celery
• Chopped pickles or relish
• Fresh parsley (optional, but it makes you look fancy)
• Shredded cheese (for melting or mixing in)
• Low-carb tortilla, lettuce leaves, or avocado boats for serving

Step-by-Step Instructions

1. Drain the Tuna

Open your can of tuna and drain it well.
The drier it is, the better your final texture will be.
Nobody wants soggy tuna mush, trust me.

2. Mix the Base

Add tuna, mayonnaise, Dijon mustard, lemon juice, garlic powder, onion powder, salt, and pepper to a bowl.
Stir it like you mean it.
Break up the chunks so everything mixes nicely.

3. Add Crunch

Mix in chopped celery and pickles.
This is what gives your tuna salad that satisfying bite.
Don’t skip it unless you enjoy soft food with zero texture.

4. Adjust the Flavor

Taste it.
Seriously, taste your food.
If it needs more lemon, add it. If you want more spice, toss in extra pepper.

5. Dress It Up

Sprinkle fresh parsley if you’re feeling extra.
Mix in shredded cheese if you want it creamier.
You can even melt the cheese on top for a warm, gooey version.

6. Serve It Your Way

Scoop it into lettuce wraps for a super light meal.
Stuff it into avocado halves for healthy fats.
Or throw it into a low-carb tortilla when you’re craving something wrap-like and carby… without the carbs.

Common Mistakes to Avoid

• Thinking you don’t need to drain the tuna well. Rookie mistake. You’ll end up with a watery mess.
• Adding too much mayo at once. Start small—you can always add more, but you can’t un-mayo your bowl.
• Skipping seasoning. Tuna is bland on its own, so show it some love.
• Using sweet relish without checking the carbs. Keto sabotage comes fast.
• Serving it immediately without letting the flavors chill. Ten minutes makes a huge difference.

Alternatives & Substitutions

• Not a fan of mayo? Swap with Greek yogurt if you’re doing lazy keto.
• Want it extra rich? Add mashed avocado to the mix.
• Hate celery? Use diced cucumber or bell pepper for crunch.
• Prefer spicy food? Add sriracha or chopped jalapeños for heat.
• Need more volume? Toss in chopped boiled eggs for a protein boost.
• Want something cheesy? Mix in cheddar, mozzarella, or pepper jack.
• Trying to impress someone? Add a dash of smoked paprika for color and flavor—even if you don’t know what paprika really does.

FAQ (Frequently Asked Questions)

Can I use flavored tuna packets instead of canned tuna?

You can, but read the label first. Some flavors are sneaky carb traps in disguise.

Can I replace mayo with only mustard?

Technically yes, but your tuna will taste like mustard’s distant cousin who never learned balance.

Do I have to add celery?

Nope. But without crunch, you’ll miss out on half the fun of tuna salad.

Can I meal-prep this for the week?

Absolutely. It actually tastes better the next day once the flavors marry like a happy keto couple.

What if I don’t have Dijon mustard?

Use regular mustard. It won’t ruin your life. Dijon just adds pretentious flavor depth.

Can I bake this tuna mixture with cheese?

Oh yes. Make a tuna melt casserole. It’s warm, cheesy, and dangerously addictive.

Is this recipe kid-friendly?

If your kid eats tuna willingly, you’ve already won at parenting. This recipe will work fine.
