Ingredients You’ll Need

For the filling, you’ll need canned tuna, hard-boiled eggs, mayonnaise, Dijon mustard, celery, red onion, and fresh lemon juice.

For the bread, use your favorite sturdy sandwich bread. Whole-grain, sourdough, multigrain, or country-style bread all work especially well.

How to Make Tuna Egg Toast Sandwich

Cook the Eggs

Place the eggs in a saucepan and cover them with water. Bring the water to a boil, then reduce the heat and cook until the eggs are firm.

Transfer the cooked eggs to ice water and let them cool before peeling.

Chop the eggs into small pieces. You want some texture rather than turning them completely into a paste.

Make the Tuna Egg Filling

Drain the tuna thoroughly and add it to a mixing bowl.

Add the chopped eggs, mayonnaise, Dijon mustard, celery, red onion, lemon juice, paprika, and black pepper.

Gently mix until everything is combined. Don’t overmix—the small pieces of egg and vegetables should remain visible throughout the filling.

Taste and adjust the seasoning. A little extra lemon juice can brighten the mixture, while more mustard adds tang.

Toast the Bread

Toast your bread until golden and crisp around the edges.

The slight crunch provides a nice contrast to the creamy filling and also helps prevent the sandwich from becoming too soft.

For an extra-rich sandwich, you can lightly brush the bread with olive oil or butter before toasting.

Assemble the Sandwich

Spoon a generous layer of tuna egg filling onto one slice of toasted bread.

Top with lettuce, sliced tomato, cucumber, or avocado if desired. Add the second slice of toast and gently press everything together.

Cut the sandwich in half and serve immediately.

Tips for the Best Tuna Egg Sandwich

Drain the Tuna Well

Extra liquid can make the filling watery. Take a moment to drain the tuna thoroughly before mixing.

Don’t Overcook the Eggs

Overcooked eggs can develop a dry texture and a stronger sulfur-like flavor. Cooking them just until firm gives the filling a better consistency.

Keep Some Texture

Avoid turning the tuna and eggs into a completely smooth paste. Small pieces of egg, celery, and onion make the sandwich much more enjoyable.

Toast the Bread

Toasting isn’t required, but it adds crunch and keeps the bread from becoming soggy.

Balance the Richness

Lemon juice and Dijon mustard are especially helpful because they cut through the creamy mayonnaise and egg yolks.

Easy Add-Ins and Variations

This sandwich is easy to customize based on what you have available.

Add diced pickles or relish for extra tang. Chopped green onions can replace red onion, while shredded carrots add sweetness and crunch.

For a spicy version, add sliced jalapeño, hot sauce, cayenne, or a pinch of red pepper flakes.

You can also mix in a little mashed avocado for extra creaminess.

How to Make It Higher in Protein

The tuna and eggs already provide a substantial amount of protein, but you can increase it further by using a high-protein or whole-grain bread.

You can also replace some of the mayonnaise with plain Greek yogurt. This adds protein while keeping the filling creamy.

What Bread Works Best?

A sturdy bread is ideal because it needs to hold the creamy filling without falling apart.

Try:

• Whole-wheat bread
• Multigrain bread
• Sourdough
• Sprouted-grain bread
• Rustic white bread
• Rye bread

If using very soft sandwich bread, toast it well before assembling.

What to Serve With Tuna Egg Toast

This sandwich pairs well with fresh and crunchy sides.

Serve it with fruit, cucumber slices, carrot sticks, a simple green salad, tomato soup, or roasted vegetables.

For a quick breakfast, pair it with fresh berries and coffee. For lunch, a small side salad makes an easy complete meal.

Make-Ahead Instructions

The tuna egg filling can be prepared ahead and refrigerated in a covered container.

For the best texture, toast the bread and assemble the sandwich just before eating. Keeping the filling separate prevents the toast from becoming soggy.

Storage

Store leftover tuna egg filling in an airtight container in the refrigerator and use it within 3 days.

Don’t leave the prepared filling at room temperature for extended periods. Keep it chilled until you’re ready to assemble the sandwich.

Frequently Asked Questions

Can I use canned tuna in oil?

Yes. Tuna packed in oil works well and gives the filling a richer flavor. Drain it well before mixing.

Can I replace mayonnaise?

Yes. Plain Greek yogurt can replace some or all of the mayonnaise if you prefer a lighter, higher-protein filling.

Can I use scrambled eggs?

Hard-boiled eggs work best because they hold their shape in the filling, but finely chopped scrambled eggs can be used in a pinch.

Can I make this gluten-free?

Yes. Simply use your favorite gluten-free bread and check that all other ingredients are certified gluten-free if necessary.

Is this good for meal prep?

Yes. Prepare the filling ahead and keep it refrigerated. Assemble each sandwich with freshly toasted bread when you’re ready to eat.
