Egg Sandwich Recipe
Introduction
This classic egg sandwich is a creamy, flavorful delight that’s perfect for any time of day. Soft boiled eggs mashed with mayonnaise and a hint of mustard create a rich filling spread between slices of buttery white bread. It’s simple, satisfying, and irresistibly delicious.

Ingredients
- 6 soft boiled eggs, at room temperature
- 1 tbsp whole egg mayonnaise (S&W brand recommended)
- 2 tsp Dijon mustard
- 2 tsp finely chopped chives (or substitute green onion)
- 1/2 tsp black pepper
- 1/8 tsp cooking or kosher salt
- 8 slices soft white sandwich bread
- Soft salted butter, for spreading on bread
Instructions
- Step 1: Place the soft boiled eggs in a bowl and crush them with a fork. Once mostly broken up, use a potato masher to mash the eggs thoroughly. Smaller pieces of egg white will make the filling creamier.
- Step 2: Add the mayonnaise, Dijon mustard, chopped chives, black pepper, and salt to the mashed eggs. Gently stir to combine. Taste and adjust salt carefully — eggs need surprisingly little seasoning.
- Step 3: Butter each slice of bread evenly. Divide the egg filling among 4 slices, spreading it edge to edge. Optionally, trim the crusts and cut the sandwiches as desired.
- Step 4: Serve the sandwiches at room temperature to enjoy the best flavor and texture.
Tips & Variations
- Use room temperature eggs to prevent the filling from becoming gelatinous or dull in flavor.
- Swap chives for finely chopped green onions if preferred, for a milder onion taste.
- Lightly toasting the bread before spreading butter adds a bit of crunch and warmth.
- For extra creaminess, add a little sour cream or Greek yogurt to the filling.
Storage
Store leftover egg filling in an airtight container in the refrigerator for up to 2 days. Assemble sandwiches fresh before serving. Reheated sandwiches tend to lose their texture, so enjoy them cold or at room temperature.

FAQs
Can I use hard boiled eggs instead of soft boiled?
Yes, hard boiled eggs work fine, but soft boiled eggs create a creamier, more tender filling that elevates the sandwich.
Is there a substitute for mayonnaise?
You can use Greek yogurt or a blend of yogurt and a little olive oil for a lighter option, though the flavor and richness will differ slightly.
