Breakfast & Brunch
This smashed avocado and egg on toast recipe delivers the perfect balance of textures—crispy toast, creamy avocado, and runny yolk—with every bite. The secret lies in high-heat toasting and precise egg cooking, transforming simple ingredients into a restaurant-worthy breakfast.
I’ve perfected this combination over years of morning experiments, ensuring the bread stays sturdy while the avocado remains silky and the egg yolk stays gloriously liquid.
The foundation starts with sturdy bread, toasted until golden and crisp, then topped with mashed avocado that’s seasoned just right—salt, pepper, and a squeeze of lemon to brighten the flavors.
A fried egg, cooked sunny-side-up or over-easy, adds richness, while a sprinkle of flaky salt and chili flakes elevates the dish to new heights. This isn’t just breakfast; it’s a flavor-packed, satisfying meal that takes less than 10 minutes to prepare.
What makes this recipe stand out is the harmony of textures: the crunch of toasted bread, the velvety avocado, and the silky yolk that breaks effortlessly. The assembly is simple but intentional—each element plays a role in creating a dish that’s both elegant and deeply comforting.
Whether you’re meal prepping for the week or craving a quick morning fix, this recipe delivers every time.
For added depth, consider optional toppings like crumbled feta, crispy bacon, or a drizzle of hot sauce. The possibilities are endless, but the core technique—crispy toast, creamy avocado, and perfect egg—remains the star. Let’s get started on creating your ideal breakfast.
Ingredients for smashed avocado and egg on toast
Simple ingredients, restaurant-quality results—crispy toast, creamy avocado, and perfect eggs.
| Ingredient | Amount | Notes |
|---|---|---|
| Sourdough Bread 🍞 | 2 slices | Thick-cut, crust removed |
| Ripe Avocados 🥑 | 1 whole | Firm but yielding to touch |
| Large Eggs 🥚 | 2 whole | Fresh, room temperature |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For toasting bread |
| Flaky Sea Salt 🧂 | ½ tsp | For finishing |
| Freshly Ground Black Pepper 🌶️ | ¼ tsp | Freshly cracked |
| Lemon Juice 🍋 | 1 tsp | Freshly squeezed |
| Chili Flakes 🔥 | ¼ tsp | For heat |
| Butter 🧈 | 1 tbsp | Unsalted, softened |
The bread is non-negotiable here. Sourdough has the perfect chew, but sturdy white bread works too. Look for slices that are at least 1/2-inch thick—thinner bread burns before toasting properly. Toast until golden and crisp; I use a cast-iron skillet for extra crunch. The avocados should give slightly when pressed (no bruises!)—Hass avocados are ideal. If they're too firm, let them sit at room temperature for 30 minutes. Butter matters too—unsalted gives you control over seasoning, and softened butter spreads easier for toasting.
No fresh chili flakes? Crushed red pepper flakes work in a pinch, but fresh has more depth. Lemon juice can be swapped for white vinegar or lime juice, though lemon's brightness is preferred. For the eggs, room temperature is key—they cook faster and more evenly. If you're short on time, crack them into a bowl first, then slide them into the pan. The olive oil for toasting? Extra-virgin adds subtle flavor, but any neutral oil works. And if you're feeling fancy, a drizzle of truffle oil after assembly takes this to the next level.
Toasted bread stays crisp for 2-3 hours if stored in an airtight container, but avocado and eggs are best used immediately. Prep the avocado mash ahead of time—store it in a bowl with plastic wrap pressed directly on the surface to prevent browning. For the eggs, cook them just before serving to maintain that perfect runny yolk. This recipe is all about freshness, so plan to assemble it right before eating. Leftovers? The bread gets soggy, but you can repurpose it for avocado toast sandwiches the next day.

Step-by-step instructions for silky avocado and egg on toast
Here's how to assemble the perfect balance of textures and flavors with minimal effort.
Toast the Sourdough to Crispy Perfection
Preheat your oven's broiler to its highest setting. Place the 2 slices sourdough bread on a baking sheet and drizzle evenly with the 1 tablespoon extra-virgin olive oil. Spread the oil with your fingers, coating the entire surface. This creates a crispy foundation that contrasts beautifully with the soft avocado.
Toast the bread under the broiler for 2-3 minutes, watching closely to prevent burning. You'll know it's perfect when the edges turn deep golden brown and the surface develops a satisfying crunch. Remove immediately and set aside on a wire rack to cool slightly—this prevents soggy toast when you add the avocado.
Prepare the Avocado Mash with Bright Acidity
While the bread toasts, cut the 1 whole ripe avocado in half, remove the pit, and scoop the flesh into a bowl. Mash with a fork until smooth but still slightly textured—this ensures a creamy yet appealing consistency. Add the 1 teaspoon lemon juice and mix thoroughly. The acidity prevents browning and brightens the avocado's natural flavor.
Season immediately with the 0.5 teaspoon flaky sea salt and 0.25 teaspoon black pepper, pressing the salt into the avocado with the back of your fork. This ensures even distribution. Taste and adjust seasoning if needed—you want a balance of saltiness and freshness that complements the eggs.
Cook the Eggs to Runny Yolk Perfection
Heat a nonstick skillet over medium-low heat and melt the 1 tablespoon butter until it foams but doesn't brown. Crack the 2 large eggs directly into the pan, spacing them apart. Cook gently for 2-3 minutes until the whites set but the yolks remain completely liquid and the edges are just barely set.
The key here is patience—don't rush the eggs. You want that signature runny yolk that pools dramatically when you cut into the toast. When the whites are just set but still slightly translucent at the edges, remove the eggs from the pan and place them on a plate. They'll continue cooking slightly from their residual heat.
Assemble with Perfect Layering
Spread the avocado mash evenly over the toasted bread slices, creating a smooth but not overly thick layer. This ensures every bite has both avocado and toast. Place one egg on each slice, positioning it slightly off-center for visual appeal. Sprinkle generously with the 0.25 teaspoon chili flakes and an extra pinch of flaky sea salt for heat and contrast.
Serve immediately while the toast remains crispy and the eggs are at their peak temperature. The chili flakes add a subtle heat that cuts through the richness of the avocado and eggs, while the flaky salt enhances all the flavors. Each bite should deliver the perfect combination of textures—crunchy toast, creamy avocado, and silky yolk.
Pro Tips For Making Smashed Avocado And Egg On Toast
- Toast It First: Pop your sourdough in the toaster before prepping the avocado—it’ll stay crisp longer. I learned this the hard way when soggy bread ruined my first batch. If you’re short on time, toast it while you crack the eggs.
- Smash the Avocado Hot: Warm the smashed avocado slightly (30 seconds in the microwave) before topping with the egg. The heat makes it creamier and helps it cling better to the toast—no more sliding-off disasters. Use a fork, not a knife, to avoid crushing it into guacamole.
- Salt the Egg Water: Add a pinch of flaky sea salt to the water when boiling eggs for soft yolks. It seasons the whites and keeps the egg from sticking to the pan later. Trust me, it’s a small step that makes a real difference.
- Use Cold Butter: Skip the olive oil for toasting—melt a pat of cold butter in the pan first. The fat coats the bread better, and the butter’s richness balances the avocado’s sharpness. (Yes, even if you’re using sourdough, which is already buttery.)
Pro cooking tips for smashed avocado and egg on toast
Crispy Toast Secrets
Use a cast-iron skillet or oven broiler for the crispiest toast—these methods create that satisfying crunch. Brush the bread with extra-virgin olive oil (not butter) before toasting to prevent sticking and enhance flavor.
For extra texture, I toast the bread until the edges are deep golden brown and the surface has visible crunch lines. Let it cool on a wire rack for 1-2 minutes before adding avocado to maintain crispness. 🍞
Avocado Texture Mastery
Mash the avocado until it’s smooth but slightly textured—this prevents it from being too heavy. Add lemon juice immediately after mashing to prevent browning and brighten the flavor. Season with flaky sea salt (like Maldon) and freshly cracked black pepper—this makes all the difference.
For extra creaminess, I sometimes add 1 tablespoon Greek yogurt to the mash, but keep it optional for purists. 🥑
Egg Cooking Precision
Cook eggs over medium-low heat in butter (not oil) for a richer flavor. The whites should be just set while the yolks remain completely liquid—this takes about 2-3 minutes. For extra insurance, I use a digital thermometer to check the yolk temperature at 145°F (perfect for runny yolks).
Slide the eggs onto a plate and let them rest for 30 seconds before serving to ensure they’re fully set but still silky. 🥚
Assembly Like a Pro
Spread the avocado evenly but not too thickly—about ¼-inch thick—so every bite has both avocado and toast. Place the egg slightly off-center for visual appeal, then sprinkle with chili flakes and extra flaky salt.
For a restaurant-style finish, I add a few microgreens or a drizzle of hot sauce (like Cholula) on the side. Serve immediately while the toast stays crispy and the yolk remains runny. ✨
Equipment Upgrades
Invest in a high-quality nonstick skillet (like All-Clad) for perfect egg cooking without sticking. A wire rack keeps toasted bread crispy longer than a plate. For avocado prep, I use a small fork instead of a spoon to mash—it gives better control over texture.
And a small bowl with plastic wrap (pressed directly on the surface) keeps avocado fresh for 2-3 hours if prepped ahead. 💡
Temperature Control
Broil the toast at 500°F for 2-3 minutes—any hotter and it burns. Cook eggs on medium-low heat to prevent overcooking the whites. If your kitchen runs hot, reduce the heat slightly and monitor closely.
The avocado should be at room temperature before mashing for the best texture—cold avocado turns mushy when mashed. 🌡️

Frequently asked questions
Can I make this ahead of time?
Toast and avocado prep can be done in advance, but eggs should be cooked fresh. Toast the bread and store in an airtight container for 2-3 hours—it loses crispness after that. Mash the avocado with lemon juice and store in a bowl with plastic wrap pressed directly on the surface to prevent browning. Cook eggs just before serving to maintain that perfect runny yolk.
What's the best bread for this recipe?
Sourdough is ideal for its sturdy texture, but any thick-cut bread works—try brioche for extra richness or rye for a heartier bite. Avoid soft breads like white sandwich bread; they get soggy too quickly. For extra crunch, toast the bread until golden brown and crispy.
How do I get the perfect runny yolk?
Cook eggs over medium-low heat in butter until whites are just set but yolks remain completely liquid (2-3 minutes). Remove from heat when edges are barely set—they'll keep cooking slightly. For extra precision, use a digital thermometer to check yolk temperature at 145°F. Let eggs rest 30 seconds before serving.
Can I add other toppings?
Try crumbled feta cheese for tang, crispy bacon bits for protein, or microgreens for freshness. A drizzle of hot sauce or chili oil adds heat, while everything bagel seasoning gives a savory crunch. Keep it simple with extra flaky salt and chili flakes for the classic version.
Why did my avocado turn brown?
Avocados oxidize when exposed to air. Prevent browning by adding lemon juice immediately after mashing and pressing plastic wrap directly on the surface. Store in the fridge for up to 1 day (though texture may soften). For browning that's already happened, mix in 1 tsp lemon juice or Greek yogurt to brighten the color.
