The tuna is key—Wild Planet or Safe Catch brands have better flavor and texture. Drain it well (squeeze out excess water with a paper towel) so your mixture isn’t soggy. For crackers, Ritz or Town House give that buttery crunch, but any sturdy cracker works. Look for tuna packed in water, not oil, to control the richness yourself.

No celery? Cucumber or bell pepper adds the same fresh crunch. Out of fresh dill? Dried dill at one-third the amount or a pinch of dried parsley works. For a lighter version, swap mayo for Greek yogurt (the full-fat kind holds up best). Want more heat? Add a dash of hot sauce or a pinch of cayenne.

This keeps 2-3 days in the fridge (store tuna mixture separately from crackers). Best served fresh, but the filling can be made a day ahead. Not freezer-friendly—the texture changes. Pack crackers separately if prepping for lunchboxes.

Step-by-Step Instructions for Tuna Crackers

Here’s how I make these quick, protein-packed bites with minimal effort and maximum flavor.

Step 1: Prepare and Drain the Tuna

Open the 2 cans Canned Tuna in Water and drain them thoroughly in a fine-mesh strainer. Press gently with a spoon to remove as much liquid as possible—this prevents the filling from becoming watery.

Transfer the drained tuna to a mixing bowl and flake it with a fork. I like to break it into small, even pieces so every bite has consistent texture. The tuna should look light and airy, not compacted.

Step 2: Mix the Creamy Filling Base

Add the 0.5 cup Mayonnaise, 1 tbsp Dijon Mustard, 1 tbsp Lemon Juice, 0.5 cup Celery, 0.25 cup Red Onion, 2 tbsp Fresh Dill, 0.5 tsp Salt, and 0.25 tsp Black Pepper to the bowl with the tuna.

Stir everything together until well combined. The mixture should hold its shape when scooped but still be spreadable. If it seems too dry, add a teaspoon more of the mayonnaise.

For extra sweetness and tang, fold in the 2 tbsp Sweet Pickle Relish. This step balances the sharpness of the red onion and adds a subtle crunch.

Step 3: Incorporate the Hard-Boiled Eggs

Peel and finely chop the 2 whole Hard-Boiled Eggs—I aim for pieces about the same size as the flaked tuna. Gently fold the eggs into the tuna mixture, being careful not to overmix and break them down too much.

The eggs add richness and a pop of color. You’ll notice the filling becomes slightly thicker and more cohesive. Taste and adjust seasoning if needed, though I rarely find it necessary.

Step 4: Assemble the Tuna Crackers

Lay out the 48 pieces Buttery Round Crackers on a clean work surface or serving platter. Spoon a generous teaspoon of the tuna mixture onto each cracker, pressing lightly to help it adhere.

This amount ensures every cracker has a satisfying layer of filling without making them difficult to eat. The buttery crackers provide the perfect crunchy contrast to the creamy tuna.

Step 5: Garnish and Serve

Lightly dust the tops of the filled crackers with 0.25 tsp Paprika for a subtle smoky note and a pop of color. If you’re serving them as open-faced bites, place each on a lettuce leaf from the 8 pieces Lettuce Leaves for a fresh, crisp base.

Arrange them on a platter and serve immediately. These are best enjoyed fresh, but they’ll hold up in the fridge for a few hours if covered. The lettuce leaves keep the crackers from getting soggy if you’re prepping ahead.
