Why This Recipe Works
This Tzatziki Tuna Salad is more than just a tuna salad makeover. It’s a busy parent’s dream! Here’s why it works so well:
- Quick & Easy: Seriously, this comes together in less than 15 minutes. Perfect for those hectic weekday lunches.
- Healthy & Delicious: Packed with protein and fresh veggies, it’s a guilt-free meal that tastes amazing.
- Kid-Approved: My kids are surprisingly picky, but they love the creamy coolness of the tzatziki and the familiar flavor of tuna.
- Make-Ahead Friendly: You can easily make the tzatziki sauce ahead of time and store it in the fridge, making this salad even faster to assemble when you’re ready to eat.
Ingredients
- 2 (5-ounce) cans tuna, packed in water, drained
- 1 cup plain Greek yogurt (I prefer whole milk for creaminess)
- 1/2 cup grated cucumber, squeezed to remove excess water
- 2 tablespoons chopped fresh dill
- 1 tablespoon lemon juice, freshly squeezed
- 1 clove garlic, minced
- 1/4 teaspoon salt, or more to taste
- 1/4 teaspoon black pepper, or more to taste
- Optional: 1/4 cup chopped red onion
- Optional: 1/4 cup Kalamata olives, pitted and chopped
Ingredient Notes
Let’s break down a few of these ingredients and why they’re important:
- Greek Yogurt: This is the base of our tzatziki, so use a good quality plain Greek yogurt. I find that whole milk Greek yogurt is the creamiest, but non-fat works too if you’re watching calories.
- Cucumber: Grating the cucumber and squeezing out the excess water is key to prevent a watery tzatziki. Trust me on this one!
- Fresh Dill: Fresh dill is essential for that authentic tzatziki flavor. Dried dill just won’t cut it here.
- Tuna: I prefer tuna packed in water for a lighter taste, but you can use tuna packed in oil if you prefer. Just be sure to drain it well!
- Kalamata Olives: Kalamata olives add a salty, briny flavor that really complements the other ingredients. If you don’t like olives, you can leave them out.
Step-by-Step Instructions
Alright, let’s get cookin’! Here’s how to make this delicious Tzatziki Tuna Salad:
- Step 1: Prepare the Cucumber: Grate the cucumber using a box grater. Place the grated cucumber in a clean kitchen towel or cheesecloth and squeeze out as much excess water as possible. This step is crucial to prevent a watery salad.
- Step 2: Combine the Ingredients: In a medium bowl, combine the Greek yogurt, squeezed cucumber, chopped dill, lemon juice, minced garlic, salt, and pepper. Stir well to combine. This is your homemade tzatziki sauce! Give it a taste and adjust the seasonings as needed.
- Step 3: Add the Tuna and Optional Ingredients: Add the drained tuna to the bowl with the tzatziki sauce. If using, add the chopped red onion and Kalamata olives. Gently stir everything together until the tuna is evenly coated with the sauce. Be careful not to overmix, or the tuna will become mushy.
- Step 4: Chill and Serve: Cover the bowl and refrigerate for at least 30 minutes to allow the flavors to meld. This step is optional, but I find that the salad tastes even better after it’s been chilled. Serve chilled and enjoy!
Expert Tips from My Kitchen
Here are a few tips and tricks I’ve learned from making this Tzatziki Tuna Salad in my own kitchen:
- Don’t skip squeezing the cucumber! This is the most important step to prevent a watery salad. Trust me, you’ll thank me later.
- Adjust the seasonings to your liking. If you like a more garlicky flavor, add an extra clove of minced garlic. If you prefer a tangier salad, add a little more lemon juice.
- For a creamier salad, use full-fat Greek yogurt. If you’re watching your calories, non-fat Greek yogurt works too, but it won’t be as creamy.
- Add a pinch of sugar to the tzatziki sauce to balance the acidity. Just a pinch will do the trick!
- Make it kid-friendly by omitting the red onion and Kalamata olives. You can also add a little bit of honey to the tzatziki sauce to make it sweeter.
- Serve it in different ways! This salad is delicious on its own, but you can also serve it in a pita pocket, on top of crackers, or as a dip with vegetables.
Storage & Meal Prep
This Tzatziki Tuna Salad is perfect for meal prepping! Here’s how to store it and make it ahead:
- Storage: Store the tuna salad in an airtight container in the refrigerator for up to 3 days.
- Reheating: This salad is best served cold, so no reheating is required!
- Make-Ahead: You can make the tzatziki sauce up to 3 days in advance and store it in the refrigerator. When you’re ready to make the tuna salad, simply add the tuna and other ingredients.
Substitutions & Variations
Want to mix things up a bit? Here are a few substitutions and variations you can try:
- Gluten-Free: This recipe is naturally gluten-free!
- Dairy-Free: Use a dairy-free yogurt alternative, like coconut yogurt or almond yogurt, to make this recipe dairy-free. Just be sure to choose an unsweetened, plain variety.
- Spicy Tuna Salad: Add a pinch of red pepper flakes or a dash of hot sauce to the tzatziki sauce for a spicy kick.
- Lemon-Herb Tuna Salad: Substitute the dill with other fresh herbs, like parsley, mint, or chives. Add a little extra lemon zest for a brighter flavor.
- Mediterranean Tuna Salad: Add chopped sun-dried tomatoes, artichoke hearts, and feta cheese for a more Mediterranean flavor.
