This avocado and egg sandwich is simple to make, full of flavor, and perfect for a satisfying brunch.
An avocado egg sandwich is a true classic, and it is easy to see why. Creamy avocado, rich fried egg, crisp buttery toast, and a little heat from hot sauce come together in a sandwich that feels special without being difficult. There are several ways to make this kind of sandwich, from avocado egg salad to boiled egg with sliced avocado, but this version uses softly smashed avocado and perfectly fried eggs for the best texture and flavor.
Smashed Avocado
You could simply slice the avocado and layer it into the sandwich, but smashing it gives you the chance to build in extra flavor. A few simple ingredients turn plain avocado into a creamy, bright, and well-seasoned filling that works beautifully with fried eggs.
Simple Smashed Avocado Ingredients
- Avocados – Choose ripe avocados that feel slightly soft but are not bruised.
- Chives – Fresh chives add a gentle onion flavor and pair especially well with eggs.
- Extra Virgin Olive Oil – This gives the avocado a smoother, silkier texture and adds a subtle richness.
- Lemon Juice – Lemon brings freshness and helps slow down browning.
- Salt & Pepper – Avocado needs proper seasoning, so do not be shy with it.
These small additions make a big difference. The olive oil helps loosen the avocado, the lemon keeps it bright, and the chives add just enough sharpness to balance the creamy texture. When smashing the avocado, keep it slightly chunky rather than completely smooth. A few lumps give the sandwich a much better bite.
Process shots: add the ingredients to a bowl, then lightly smash until combined.
Perfect Fried Eggs
Frying eggs may seem straightforward, but a few small details can take them from average to excellent. For this avocado egg sandwich, you want eggs with set whites and a soft, runny yolk. The yolk mixes with the smashed avocado and hot sauce, creating a rich, delicious filling.
Tips for frying eggs
- Use Fresh Eggs – Fresh eggs hold their shape better in the pan. Older eggs tend to spread out more as they cook.
- Bring Them Toward Room Temperature – This is not essential, but it can help the eggs cook more evenly.
- Season Well – Add salt and pepper near the end of cooking so the eggs are flavorful without affecting their texture too early.
Let there be butter!
Butter is ideal for frying the eggs in this sandwich. As it melts, it creates a rich base for cooking and allows you to baste the egg whites. Basting helps the tops cook gently without needing to flip the eggs, while also coating them in buttery flavor. This keeps the whites tender and the yolks beautifully runny.
Once the eggs are cooked, do not wipe out the pan. The leftover butter is perfect for toasting the bread, giving it a golden crust and a deeper flavor.
Process shots: melt butter in a pan, crack in the eggs, baste the whites with butter, then season before removing from the pan.
What bread should you use?
A sturdy bread works best for an avocado and fried egg sandwich because the fillings are soft and rich. Sourdough, white bloomer, or artisan-style bread are all good choices. A sesame-crusted loaf also works very well, adding a little nuttiness and extra texture. Toasting the bread in the leftover butter helps it hold up better and makes the sandwich taste even better.
Process shots: add the bread to the leftover butter and fry both sides until golden.
Avocado Egg Sandwich
Once the avocado is smashed, the eggs are fried, and the bread is toasted, it is time to build the sandwich. One egg per sandwich is enough, but you can use two if you want a more filling brunch sandwich. The key is to layer the smashed avocado first so it acts as a creamy base for the egg.
Hot sauce
A few drops of hot sauce are highly recommended. It adds sharpness, heat, and acidity, which help cut through the richness of the butter and egg yolk. Even if you do not usually enjoy spicy food, a small amount can lift the flavor of the whole sandwich without making it too hot.
What else could I add to this sandwich?
This avocado egg sandwich is delicious as it is, but you can add other breakfast-style ingredients if you want to make it heartier. Bacon, sausage, hash browns, or tomato would all work well. Keep in mind that the sandwich is already rich and creamy, so any extra ingredients should complement the avocado and egg rather than overpower them.
Process shots: place toast on a board, add smashed avocado, top with egg, add an optional second egg, drizzle with hot sauce, then finish with the second slice of toast.
What to serve with an Avocado Egg Sandwich?
- Crisp/Chip Recommendation: Cheese and onion crisps work nicely here. A sturdy crisp is useful for scooping up any runny yolk that escapes.
- Side Recommendation: Hash brown patties make a great brunch side.

Equipment
- Large pan and spatula or turner, for frying the eggs
- Medium bowl, for the smashed avocado
- Sharp knife and chopping board, for the chives and bread
Ingredients
- 6 small to medium slices of bread, such as sesame white bloomer
- 3 to 6 eggs, using 1 to 2 eggs per sandwich
- 2 medium avocados, peeled, pitted, and roughly diced
- 1 tbsp butter, or as needed
- 1 tbsp finely diced fresh chives
- 1/2 tbsp extra virgin olive oil
- 1/2 tbsp lemon juice
- Hot sauce, to serve
- Salt & pepper, as needed
Instructions
- Place the diced avocado in a medium bowl with the chives, extra virgin olive oil, lemon juice, salt, and pepper. Smash with a fork until combined, keeping a few small chunks for texture. Set aside.
- Melt 1 tablespoon of butter in a large pan over medium heat. Carefully crack in three eggs, keeping them close to the pan as you do so. Baste the egg whites with the melted butter to help them cook evenly while keeping the yolks runny. Season with salt and pepper near the end of cooking.
- Once the egg whites are fully opaque, remove the eggs from the pan. If using two eggs per sandwich, cook the remaining eggs in the same way, adding a little more butter if needed.
- Place the bread in the leftover butter and toast both sides for a couple of minutes, or until golden and crisp.
- Build each sandwich with one slice of toast, a generous layer of smashed avocado, one or two fried eggs, and a drizzle of hot sauce. Top with the second slice of toast and serve immediately.
Notes
a) Over easy, medium, or hard: You do not have to make sunny-side-up eggs. For over-easy eggs, cook until the whites are nearly set, then flip and cook for about 30 seconds. For over-medium or hard eggs, flip sooner and cook longer until the yolk reaches your preferred texture.
b) Can I use scrambled eggs? Yes. If using scrambled eggs, 2 eggs per person is recommended.
c) Do I have to add hot sauce? A few drops are recommended because hot sauce adds tang and helps balance the richness of the egg yolk and butter. Chilli flakes do not give the same vinegary flavor.
d) Calories: Nutrition is calculated per sandwich with 1 egg each.
