Waldorf Tuna Salad

Waldorf Chicken Salad is a classic for a reason—crisp apples, crunchy walnuts, and a creamy dressing make for a bright, satisfying bite. This Waldorf Tuna Salad keeps that same beloved flavor profile but swaps canned tuna for chicken, making it faster and even more pantry-friendly. Canned tuna is reliable, affordable, and simple to prepare, so this version is ideal for a quick, healthy lunch or an easy meal prep option.

This recipe combines flaky tuna with sweet grapes and apples, crunchy walnuts and celery, and a bright lemon-mayo dressing. It’s naturally refreshing, adaptable to dietary preferences, and pairs perfectly with greens, on whole-grain bread, or stuffed into an avocado for an extra-satisfying meal.

Ingredients

1. 3 (5 oz) cans of tuna in water, drained
2. 1/2 cup red seedless grapes, halved
3. 1/2 cup finely diced yellow onion (about 1/4 of an onion)
4. Zest of 1/2 lemon (about 1 tsp zest)
5. Juice of 1 lemon (about 2 tbsp)
6. 4 tbsp mayonnaise (homemade or your preferred brand)
7. 3/4 cup coarsely chopped walnuts
8. 1/2 cup diced celery (about 2 ribs)
9. 1 medium apple, cubed (about 1 1/2 cups)
10. 1 tsp kosher salt
11. 1/4 tsp garlic powder
12. Black pepper, to taste

Instructions

1. Place the drained tuna into a large mixing bowl and break it up gently with a fork so it flakes but still retains texture.
2. Add the halved grapes, diced onion, lemon zest, lemon juice, mayonnaise, chopped walnuts, diced celery, and cubed apple.
3. Season with kosher salt, garlic powder, and black pepper. Toss everything together until ingredients are evenly coated and combined. Taste and adjust seasoning or lemon to your preference.
4. Cover and refrigerate the salad for at least 1 hour before serving to let the flavors meld. The salad keeps well in the fridge for up to 5 days and often tastes even better the next day.

Notes

• Serving suggestion: For a more filling meal, stuff this tuna salad into a halved, pitted avocado. It also makes a great sandwich filling or topping for mixed greens.
• Texture tips: If you prefer a creamier salad, add an additional tablespoon or two of mayonnaise. For extra crunch, substitute or add toasted pecans or almonds.
• Apple choices: Choose a crisp, tart variety like Gala, Honeycrisp, or Granny Smith depending on how sweet or tart you’d like the salad to be.

Variations

There are many simple ways to adapt this Waldorf Tuna Salad to suit different tastes or dietary needs. Swap Greek yogurt for part or all of the mayo for a tangier, lower-fat option. Omit grapes for a nut-and-apple-forward version, or add finely chopped fresh herbs—such as parsley or dill—for added brightness. For a grain-free, low-carb meal, serve inside lettuce leaves or halved avocados.

Storage and Meal Prep

Store the salad in an airtight container in the refrigerator for up to five days. Drain any excess liquid from apples and grapes before mixing to avoid a watery salad. If packing for lunch, keep the salad chilled and use an insulated lunch bag to maintain freshness.

Why This Works

This Waldorf Tuna Salad balances sweet, savory, and crunchy elements: grapes and apple provide sweetness and juiciness, walnuts add satisfying crunch and richness, celery contributes a crisp bite, and lemon brightens the entire dish. Canned tuna is an accessible source of protein and allows this recipe to come together quickly, making it ideal for busy weeknights or simple meal prep.
