Avocado Egg Salad Sandwich with Greek Yogurt

Avocado Egg Salad Sandwich with Greek Yogurt

This avocado egg salad sandwich combines chopped hard-boiled eggs, ripe avocado, Greek yogurt, Dijon mustard, and chives. Whole-grain toast and crisp cucumber give the creamy filling structure, making it a practical protein-rich lunch that can be assembled in about 20 minutes.

Why This Recipe Works

Greek yogurt provides tang and creaminess without requiring a large amount of mayonnaise. Avocado adds richness and helps bind the eggs, while lemon juice keeps the flavour bright. The cucumber and toasted bread are important contrasts to the soft filling, so the sandwich does not feel one-dimensional.

Ingredient Notes

Use eggs that are fully cooled before chopping. Warm eggs can soften the avocado too quickly and make the filling loose. A ripe but firm avocado is best because it blends slightly into the dressing while leaving some pieces intact.

Plain Greek yogurt works at either 2% or full-fat. Lower-fat yogurt produces a slightly sharper filling, while full-fat yogurt gives a rounder texture. The lemon juice is a small but useful addition: it balances the egg and mustard and helps slow browning.

How to Make the Sandwich

Boil the eggs by bringing them to a boil, removing the pan from the heat, and leaving them covered for 10 minutes. Cool them in cold water before peeling so the yolks stay firm and the shells release more easily.

Mix the yogurt, Dijon, lemon juice, salt, and pepper first. Add the chopped eggs, avocado, and chives afterwards and fold gently. Stop while the mixture is still slightly chunky; overmixing turns the avocado into a paste and can make the filling watery.

Toast the bread and layer cucumber underneath the filling. Assemble only when ready to eat, or keep each component separate for lunch preparation.

Serving Ideas

Serve with tomato soup, a green salad, or vegetable sticks. For extra heat, add chilli flakes or a little hot sauce. Thinly sliced radish, tomato, celery, or dill can add more crunch and freshness without changing the basic method.

Storage and Meal Prep

The filling can be refrigerated in a covered container for up to 1 day. Press parchment or food-safe wrap directly against the surface to reduce air exposure, then stir briefly before serving. Store the bread and cucumber separately and assemble at lunchtime. Do not freeze the completed filling because avocado and boiled egg change texture after thawing.

Frequently Asked Questions

Can I make this sandwich without Greek yogurt?

Yes. Use mayonnaise, cottage cheese blended until smooth, or an unsweetened plant-based yogurt. The flavour and nutrition will change depending on the substitute.

How chunky should the egg salad be?

Keep some chopped egg and avocado pieces visible. A lightly chunky mixture gives the sandwich better texture and holds together more reliably than a completely smooth mash.

Can I use different bread?

Yes. Rye, sourdough, seeded bread, or a whole-wheat wrap all work. Toast softer breads before assembling so they hold the filling without tearing.
