An egg sandwich Los Angeles style pairs soft scrambled eggs with creamy avocado, ripe tomato, and a little chile on toasted sourdough. It is a fresh, filling breakfast built from familiar California ingredients, with crisp bread to keep every bite balanced.
Ingredients
- 4 large eggs (about 200 g without shells)
- 2 tablespoons (30 ml) whole milk or water
- ¼ teaspoon fine salt (1.5 g), plus more to taste
- ⅛ teaspoon black pepper (0.3 g)
- 1 tablespoon (14 g) unsalted butter
- 4 slices sourdough bread, about 1 inch (2.5 cm) thick (about 240 g total)
- 1 medium ripe avocado (about 200 g whole; 120 g flesh)
- 1 teaspoon (5 ml) fresh lemon juice
- 1 small ripe tomato, cut into 4 thin slices (about 100 g)
- 2 tablespoons (30 g) mayonnaise
- 1 teaspoon (5 ml) hot sauce, or to taste
- 2 tablespoons (10 g) thinly sliced scallions
Instructions
- Set out the ingredients and toast the bread: use a toaster or heat a dry skillet over medium heat and toast the slices for about 2 minutes per side, until golden and crisp. Set aside. Toasting the bread first helps prevent the avocado and tomato from making it soggy.
- Halve the avocado, remove the pit, and scoop the flesh into a small bowl. Add the lemon juice and a pinch of salt, then mash with a fork until chunky but spreadable. Keep a few small pieces rather than making a completely smooth puree.
- Whisk the eggs, milk, ¼ teaspoon salt, and pepper in a bowl until the whites and yolks are fully combined. Warm the butter in a nonstick skillet over medium-low heat until melted and foaming gently. Pour in the eggs.
- As the eggs begin to set, use a silicone spatula to draw them slowly from the pan’s edge toward the center. Tilt the pan to let uncooked egg flow into the open spaces. Continue for about 3 to 4 minutes, folding gently, until the eggs are just set and moist. Check with a food thermometer: the USDA FSIS safe minimum for egg dishes is 160°F (71°C). Do not serve undercooked eggs; cook longer if needed.
- Mix the mayonnaise and hot sauce in a small bowl. Spread it over one side of each toast slice. Divide the mashed avocado between two slices, then add the tomato slices and scallions.
- Spoon the hot scrambled eggs onto the avocado-topped bread. Close each sandwich with the remaining toast, press lightly, and serve promptly while the eggs are warm and the bread is crisp. Cut in half if preferred.
Tips
- Use medium-low heat for soft, tender curds. High heat can make eggs rubbery before they are safely cooked through; keep stirring gently and verify the temperature with a food thermometer.
- Choose ripe but not mushy avocado and a firm, flavorful tomato. If the tomato is very juicy, blot its slices with a paper towel before layering them onto the toast.
- No sourdough? Use country-style wheat bread, a sturdy English muffin, or a toasted bagel. Softer sandwich bread works too, but toast it well so it can support the fillings.
- For a milder sandwich, leave out the hot sauce or use a small pinch of smoked paprika. Add salt to the avocado sparingly: the eggs and mayonnaise already contribute seasoning.
Serving Suggestions
Serve the sandwiches immediately with fresh fruit, a simple green salad, or breakfast potatoes. For a light brunch plate, add sliced oranges or melon and coffee or tea. If serving a group, keep the components separate and assemble each sandwich just before eating; this preserves the toast’s crunch and keeps the eggs warm.
For a more substantial meal, offer extra hot sauce at the table and a small bowl of dressed greens. The sandwich is rich from the egg, avocado, and mayonnaise, so crisp or juicy sides are a useful contrast.
Variations
Add a slice of Monterey Jack or sharp cheddar over the eggs while they are still hot, allowing it to soften before assembling. A handful of baby spinach can be folded into the eggs during the last minute of cooking; cook it until wilted and continue until the egg mixture reaches 160°F (71°C).
For extra texture, add 2 strips of cooked bacon per sandwich, or use cooked plant-based bacon. For a meat-free variation with a little bite, add thinly sliced pickled jalapeños. You can also replace the tomato with a few thin cucumber slices, though the result will be cooler and less juicy.
To make an open-faced version, use one thick slice of toast per serving and arrange the avocado, tomato, and eggs on top. It is easier to eat with a knife and fork, but less portable than the closed sandwich.
Storage and Reheating
This sandwich is best eaten as soon as it is assembled. If you have leftovers, refrigerate them within 2 hours of cooking; keep them in a covered container at 40°F (4°C) or colder and eat within 3 to 4 days. The assembled bread will soften, and avocado may darken, so for better texture store cooked eggs separately from the toast and fresh toppings. Do not leave the sandwich at room temperature for more than 2 hours, or 1 hour when the temperature is above 90°F (32°C).
Reheat the eggs in a covered microwave-safe dish in short bursts, stirring between bursts, or warm them gently in a skillet with a teaspoon of water. Reheat leftovers to 165°F (74°C). Toast fresh bread and add freshly cut avocado and tomato after reheating; do not reheat the assembled sandwich with its fresh toppings.
Frequently Asked Questions
Can I make the eggs ahead?
Yes. Cook the eggs, cool them promptly, and refrigerate in a covered container within 2 hours. For best quality, use them within 3 to 4 days, reheat to 165°F (74°C), and assemble with fresh toast and toppings.
How do I keep the sandwich from getting soggy?
Toast the bread until crisp, spread a thin layer of mayonnaise as a barrier, and avoid stacking wet tomato directly against the bread. Blot juicy tomato slices and assemble only shortly before serving.
Can I use hard-boiled eggs instead of scrambled eggs?
Yes. Use 2 hard-boiled eggs per sandwich, sliced or mashed with a little mayonnaise. Cook whole eggs until the yolk and white are firm, then cool them promptly before peeling and assembling.
What can I use instead of mayonnaise?
Use plain Greek yogurt or softened cream cheese in the same amount. Yogurt tastes tangier and is thinner; cream cheese is richer and spreads more thickly. You can also omit the spread, though it will be less creamy.
Is this sandwich spicy?
Only mildly, and the heat depends on the hot sauce. Start with a few drops or omit it entirely, then serve more on the side so each person can adjust the heat.
Can I pack it for lunch?
It is possible, but the toast softens over time. Pack it in an insulated lunch bag with a cold pack, keep it at 40°F (4°C) or colder, and eat it within 2 hours if it is not temperature-controlled. For better texture, pack the fillings separately and assemble just before eating.
