Ingredients

Tuna Use canned tuna in its own juice or water, drained well. You’ll need about 5 oz (150 g) of drained tuna — check the drained weight on the label, since a standard 5-oz can yields closer to 4 oz once the liquid is poured off. It provides the savory base for this toast and pairs naturally with the creamy eggs and tangy capers.

Hard-Boiled Eggs Two hard-boiled eggs add richness, texture, and extra protein. Cook them until the whites and yolks are fully set, then cool and peel before mixing.

Greek Yogurt Plain Greek yogurt creates a creamy tuna and egg mixture without mayonnaise. Choose unsweetened yogurt for the best savory flavor.

Capers Capers bring a distinctive briny, slightly tangy flavor that cuts through the richness of the eggs and makes the tuna mixture taste brighter. If they’re packed in brine, drain them before adding; if they’re salt-packed, rinse them first.

Extra Virgin Olive Oil A tablespoon of extra virgin olive oil adds richness and helps the ingredients come together.

Whole-Grain Bread Toasted whole-grain bread provides a hearty, crunchy base that complements the soft, creamy topping. Sourdough also works well if you prefer a tangier flavor.

Balsamic Glaze A small drizzle adds a sweet-and-tangy finish that balances the salty capers and savory tuna.

Salt and Black Pepper Ground black pepper adds gentle warmth. Use salt sparingly at first because capers and canned tuna can already be salty.

How to Make High-Protein Tuna and Egg Toast with Capers

Step 1: Prepare the Eggs

Hard-boil two eggs if you haven’t already: gently lower them into boiling water and cook for 10–12 minutes, then transfer to a bowl of ice water for about 5 minutes. Peel and place them in a medium bowl.

Step 2: Make the Tuna and Egg Mixture

Add the drained tuna, Greek yogurt, and capers to the eggs. Mash everything together with a fork until the mixture is combined but still has a little texture.

Step 3: Season

Add the ground black pepper, salt, and extra virgin olive oil. Mix well, then taste and adjust the seasoning if needed.

Step 4: Toast the Bread

Toast two slices of whole-grain bread until golden and crisp. A sturdy slice works best because it holds the creamy topping without becoming soggy too quickly.

Step 5: Assemble the Toast

Divide the tuna and egg mixture between the two slices of toast, spreading it evenly over each piece.

Step 6: Finish and Serve

Drizzle with balsamic glaze and serve immediately while the bread is crisp. Add fresh herbs or a few extra capers if desired.

Expert Tips

• Drain the tuna thoroughly. Excess liquid can make the topping watery and soften the toast.
• Use cold eggs for easier preparation. Hard-boiled eggs can be cooked in advance and stored in the refrigerator.
• Keep some texture. Mash the ingredients with a fork rather than blending them into a completely smooth paste.
• Toast the bread just before serving. This helps preserve the contrast between the crunchy bread and creamy topping.
• Taste before adding salt. Capers and tuna can contribute plenty of saltiness.
• Add the balsamic glaze last. A light drizzle adds flavor without overwhelming the tuna and capers.

Variations

Add Fresh Herbs Chopped parsley, chives, or dill add freshness and work particularly well with tuna and eggs.

Make It Extra Tangy Add a few more capers or finely chopped pickles for an extra-briny, tangy flavor. For a version with avocado, pesto, and cornichons, try our Creamy Tunacado Toast with Pesto and Pickles.

Add Crunchy Vegetables Top the toast with thinly sliced cucumber, radishes, or red onion for extra freshness and texture.

Give It a Little Heat Add a pinch of chili flakes or freshly cracked black pepper for a gentle kick.

Choose Your Favorite Bread Whole-grain bread adds a hearty flavor, while sourdough offers a tangy contrast. Rye bread is another excellent option.

What to Serve With Tuna and Egg Toast

Make this toast part of a balanced meal by serving it with:

• Fresh cucumber and tomato slices
• A simple green salad
• Sliced avocado
• Fresh fruit
• Roasted cherry tomatoes
• A light vegetable soup

For breakfast, fresh fruit makes an easy side. For lunch, a crisp green salad or sliced vegetables complement the creamy tuna topping.

Storage

Store any leftover tuna and egg mixture in an airtight container in the refrigerator and use it within 3 days, provided the ingredients were freshly prepared and properly refrigerated.

For the best texture, store the mixture separately from the bread and assemble the toast just before eating. Don’t leave the prepared mixture at room temperature for more than 2 hours (1 hour if it’s above 90°F), in line with USDA guidance on leftovers.

Frequently Asked Questions

Is tuna and egg toast high in protein?

Yes. Tuna, eggs, and Greek yogurt are all sources of protein. The exact amount per serving depends on the tuna brand, yogurt type, bread, and serving size.

Can I make the tuna and egg mixture ahead of time?

Absolutely. Prepare the mixture in advance and refrigerate it in an airtight container. Toast the bread and assemble the servings just before eating.

Can I use mayonnaise instead of Greek yogurt?

Yes. You can substitute mayonnaise for the Greek yogurt, although the flavor and nutritional profile will change. Plain Greek yogurt gives this version its fresh, tangy taste.

What type of tuna works best?

Canned tuna in water or its own juice is a convenient choice. Drain it well before mixing. Tuna packed in olive oil can also work, but the finished mixture will be richer.

Can I use a different type of bread?

Is this recipe suitable for meal prep?

The tuna and egg mixture is suitable for preparing ahead. Keep it refrigerated and assemble each toast when you’re ready to eat for the best texture. If you’re prepping tuna lunches for the week, our Mediterranean Tuna Pasta Salad is another easy make-ahead option.
