Ingredients
Egg Mayo Filling
- 4 large eggs
- 3 tablespoons mayonnaise
- 1 teaspoon mustard sauce
- 2 tablespoons finely chopped onion
- 2 tablespoons fresh parsley, finely chopped
- Salt, to taste
- ¼–½ teaspoon freshly ground black pepper, to taste
For the Sandwich
- 4 slices bread
- Butter, for spreading
Instructions
1. Boil the Eggs
Place the eggs in a saucepan and cover completely with cold water.
Bring the water to a boil over medium-high heat. Once boiling, reduce the heat slightly and cook for 9–10 minutes for fully set yolks.
Transfer the eggs immediately to a bowl of ice water and let them cool for at least 5 minutes.
Peel the eggs and pat them dry.
2. Chop the Eggs
Place the peeled eggs in a bowl and roughly chop them with a knife or mash them lightly with a fork.
For the best texture, leave some small chunks of egg rather than making the mixture completely smooth.
3. Make the Egg Mayo Filling
Add the mayonnaise, mustard sauce, chopped onion, and fresh parsley.
Season with salt and black pepper.
Gently mix everything together until the eggs are evenly coated and the filling is creamy but still slightly chunky.
Taste and adjust the seasoning as needed.
4. Prepare the Bread
Spread a thin layer of butter over one side of each bread slice.
For a toasted sandwich, place the bread butter-side down in a skillet over medium-low heat and toast until lightly golden and crisp.
You can also leave the bread soft for a classic cold egg sandwich.
5. Assemble
Divide the egg mayo mixture evenly between two slices of bread.
Spread it all the way toward the edges, but avoid making the layer excessively thick.
Top with the remaining bread slices.
Press gently and cut each sandwich in half.
6. Serve
Serve immediately while the bread is crisp and warm, or chill the assembled sandwiches for a refreshing cold lunch.
For the best texture, enjoy shortly after assembling.
Chef’s Tips
- Don’t overcook the eggs. A fully cooked but tender yolk makes a much better filling.
- Chop the eggs rather than completely mashing them for a pleasant combination of creamy and chunky textures.
- Finely chop the onion so it distributes evenly throughout the filling.
- Add the mayonnaise gradually if you prefer a thicker egg filling.
- For extra freshness, add a small squeeze of lemon juice.
- Toasting the bread adds a wonderful contrast to the creamy filling.
Easy Variations
🧀 Cheesy Egg Mayo Sandwich
Add 2 tablespoons of grated cheddar or a slice of cheese before closing the sandwich.
🌶️ Spicy Egg Mayo
Add ½ teaspoon chili flakes, hot sauce, or finely chopped jalapeño.
🥒 Fresh & Crunchy

🥓 Breakfast Style

🥑 Avocado Egg Mayo

🌿 Herb Egg Mayo

Storage
For food safety and best quality, store the egg mayo filling in an airtight container in the refrigerator and use within 3 days.
Keep the bread separate until you’re ready to eat if preparing the sandwiches ahead of time, as this prevents the bread from becoming soggy.
The Result
Creamy eggs, tangy mustard, crisp onion, fresh parsley, and buttery bread make this simple Egg Mayo Sandwich incredibly satisfying. It’s quick enough for a weekday breakfast and delicious enough for a packed lunch or afternoon snack. 🥚🥪
