Breakfast & Brunch
This smashed avocado and egg on toast recipe delivers the perfect balance of crispy crust, creamy avocado, and a perfectly runny yolk that ties everything together. The secret lies in high-heat toasting for that golden crunch, while the avocado gets a simple seasoning that enhances its natural richness.
I've perfected this technique over countless breakfasts—it's the kind of meal that transforms a lazy morning into something special.
The magic happens in the details: toast your bread until it's just crisp enough to hold up to the creamy avocado and runny yolk, then mash the avocado with a pinch of salt, pepper, and a squeeze of lemon for brightness.
Cook your egg sunny-side-up or fried for that perfect yolk, and let the flavors meld together on the plate. This isn't just breakfast—it's a textural and flavor experience that starts your day right.
What you'll end up with is a plate that's visually stunning and impossible to resist: a crispy toast base, velvety avocado, and a perfectly cooked egg that oozes golden yolk when you cut into it.
The contrast of textures and temperatures makes every bite satisfying, while the seasoning keeps it balanced. It's simple enough for a weekday but impressive enough for brunch with friends.
For a twist, try swapping the egg for a tofu scramble or adding chili flakes for a kick. The possibilities are endless, but the foundation—great bread, ripe avocado, and a well-cooked egg—is what makes this dish truly special. Let's get started on creating your perfect plate.
Ingredients for smashed avocado and egg on toast
Crispy toast meets velvety avocado and runny yolk perfection—just five ingredients transform breakfast into magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Avocados 🥑 | 1 whole | Use Hass avocados, slightly soft |
| Large Eggs 🥚 | 2 whole | Fresh, room temperature preferred |
| Sourdough Bread 🍞 | 4 slices | Thick-cut, day-old works best |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For toasting bread |
| Flaky Sea Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | ¼ tsp | Freshly cracked for best flavor |
| Fresh Lemon Juice 🍋 | 1 tsp | Brightens avocado flavor |
| Butter 🧈 | 1 tbsp | Unsalted, for cooking eggs |
| Red Chili Flakes 🌶️ | ⅛ tsp | Optional for heat kick |
| Fresh Chives 🌿 | 1 tbsp | Chopped, for garnish |
Avocados are the star here, so pick ripe ones—they should yield slightly to gentle pressure. Whole Foods or Trader Joe's usually have the best selection, but check your local market's produce section for that perfect spotty texture. Eggs should be fresh but room temperature—cold eggs won't flow right when smashed. For the bread, sourdough gives that perfect chew, but brioche or whole grain work too if that's what you've got. Toast it until it's golden and crisp—this is non-negotiable for that perfect crunch.
No sourdough? Brioche or even good-quality white bread will work—just make sure it's thick-cut. Out of fresh chives? Green onions or parsley add a nice brightness. The butter for cooking eggs can be swapped for olive oil if you're out, but trust me on the full-fat version—it makes all the difference. For extra richness, add a drizzle of crème fraîche on top of the avocado mash. And if you're feeling adventurous, try a poached egg instead of fried—just needs a little more time in the water.
Avocados brown fast, so squeeze lemon juice right before serving—this keeps them bright and prevents that sad brown haze. Store leftover avocado mash in an airtight container with a thin layer of plastic wrap touching the surface to prevent browning. The toast stays crispy for about 20 minutes after toasting, so assemble right before eating. Eggs reheat beautifully—just pop them in a 350°F oven for 5-7 minutes to restore that runny center. Make a double batch of avocado mash and keep it in the fridge for up to 2 days—perfect for quick breakfasts.

Step-by-step instructions for perfect smashed avocado and egg toast
Here's how to create the ultimate breakfast: crispy toast, velvety avocado, and runny yolk perfection.
Toast the Sourdough to Crispy Perfection
Preheat your oven to 375°F for maximum crispiness. Arrange the 4 slices sourdough bread on a baking sheet, spacing them about 1 inch apart. Drizzle each slice with ½ tablespoon extra-virgin olive oil—just enough to lightly coat the surface without making it soggy.
Toast for 8-10 minutes until the edges are deep golden brown and the bread feels crisp throughout. Watch closely after 6 minutes—if the oven runs hot, pull them out early. The key is that crispy crust that holds up to the avocado without getting mushy. Let the toast cool slightly before assembling—just enough to handle, but still warm.
Prepare the Avocado Mash with Zesty Flavor
Cut the 1 whole ripe avocado in half, remove the pit, and scoop the flesh into a bowl. Mash it with a fork until smooth, then stir in the 1 teaspoon fresh lemon juice—this prevents browning and brightens the flavor. Add the 0.5 teaspoon flaky sea salt and 0.25 teaspoon freshly ground black pepper, mixing well.
Here's the thing—don't overmix. You want a smooth but slightly textured mash that clings beautifully to the toast. If it's too thick, add a tiny pinch more lemon juice. Taste and adjust seasoning—you want that perfect balance of creamy, tangy, and salty. The avocado should be ready to spread when it's glossy and holds its shape on the fork.
Cook the Eggs to Runny Yolk Perfection
Heat a nonstick skillet over medium-low heat and melt the 1 tablespoon butter. Crack the 2 whole large eggs into the pan, spacing them apart. Let them cook undisturbed for 3-4 minutes until the whites are set but the yolks remain completely runny.
I know it's tempting to rush this, but patience is key. You want that perfect contrast of firm whites and liquid gold in the center. If the butter starts to brown too quickly, reduce the heat slightly. When the whites are just set but still slightly translucent at the edges, they're ready. Transfer to a plate and let them rest for 1 minute before serving—this keeps the yolks intact.
Assemble the Toast with Perfect Technique
Spread the avocado mash evenly over the toast, creating a smooth layer that reaches all the way to the edges. Place one egg on each slice, gently pressing down just enough to create a slight indentation in the yolk. Sprinkle with the 0.125 teaspoon red chili flakes (if using) and a pinch more flaky sea salt.
Here's where it gets fun—top each with ½ tablespoon chopped fresh chives. The chives add a fresh, oniony brightness that cuts through the richness. Serve immediately while the toast is still crisp, the avocado is fresh, and the eggs are at their perfect temperature. The first bite should deliver that magical combination of textures: crispy bread, creamy avocado, and that glorious runny yolk.
Pro Tips For Making Smashed Avocado And Egg On Toast
- CRANK THE PAN HOT: That egg needs to sizzle immediately—cold pans mean sad, rubbery whites. Heat your skillet over medium-high until a drop of water dances and evaporates in 2 seconds. I used to rush this, and my eggs turned out greasy instead of crisp. Trust me, the first 10 seconds of cooking matter more than you think.
- SMASH THE AVOCADO WITH A FORK: Skip the spoon—it’s slow and messy. Use the tines of a fork to press down and spread the avocado directly on toast. This also helps break up any stubborn pits hiding in there. Bonus: the ridges from the fork make it look intentional, not sloppy.
- TOAST THE BREAD UNTIL CRISP: Sourdough loves heat, but most people under-toast it. Push your slices until they’re golden and slightly charred at the edges—you should hear a satisfying crackle. Cold toast ruins the whole vibe, and soggy bread is a crime when you’ve got that perfect runny yolk.
- SALT THE EGG BEFORE IT’S DONE: Toss in that flaky sea salt when the whites are just set but the yolk’s still jiggly. It’ll melt into the egg instead of sitting on top like a forgotten garnish. I learned this after watching my salt disappear into the plate. Works for the avocado too—just a pinch while mashing.
Flavor customization for this recipe
Spicy Kick Boost
Add ½ teaspoon smoked paprika or ¼ teaspoon cayenne pepper to your avocado mash for a smoky-sweet or fiery heat. I love using Penzeys Smoked Paprika—it adds depth without overpowering. For a balanced heat, sprinkle ½ teaspoon of Tajín on top after assembling. 🌶️
Herb Infusions
Swap chives for cilantro or dill to brighten the dish. I often mix 1 tablespoon chopped cilantro with ½ tablespoon chopped dill for a Mediterranean twist. Fresh herbs add freshness and contrast beautifully against the richness of the avocado and egg.
Umami Depth
Add a dash of soy sauce or fish sauce to your avocado mash for umami richness. Start with ½ teaspoon soy sauce and adjust to taste—it enhances the savory notes without overpowering. For a vegan option, use ½ teaspoon coconut aminos instead.
Sweet & Tangy
Drizzle 1 teaspoon honey or maple syrup over the avocado mash for a sweet contrast. I like adding ½ teaspoon lime zest to complement the sweetness. This works especially well with spicy elements, balancing the heat with natural sweetness.
Crunchy Toppings
Add texture with toasted pumpkin seeds or crumbled bacon. Toast 1 tablespoon pumpkin seeds in a dry pan for 2-3 minutes until golden, then sprinkle over the assembled toast. For extra indulgence, top with 2 strips cooked bacon, crumbled, for a salty crunch.
Vegan Twist
Replace eggs with a tofu scramble or chickpea flour omelet. Sauté ½ cup crumbled firm tofu with ½ teaspoon turmeric and ¼ teaspoon garlic powder until golden. The texture mimics a soft egg, and the flavors still shine. 🌱

Frequently asked questions
Can I use whole-grain bread instead of sourdough?
Whole-grain bread adds a nuttier flavor and extra fiber, but it may toast slightly faster. Use medium heat and check at 6 minutes to avoid burning. For best results, lightly toast the bread first in a toaster, then finish in the oven for that extra crunch.
How do I prevent the avocado from turning brown?
Squeeze 1 teaspoon lemon juice directly onto the avocado mash right before serving. For longer storage, press plastic wrap directly onto the surface of the avocado in the bowl to block oxygen. If browning happens, mix in a pinch of salt—it helps mask the oxidation while adding flavor.
What's the best way to cook the egg for a runny yolk?
Use medium-low heat and cook for exactly 3-4 minutes with the pan uncovered. The key is patience—resist the urge to peek! For extra insurance, use room-temperature eggs and a nonstick skillet. If your stove runs hot, reduce heat to medium to avoid overcooking.
Can I make this recipe ahead of time?
Toast the bread and mash the avocado up to 1 day ahead, storing separately in airtight containers. Reheat toast in a 350°F oven for 5 minutes to restore crispiness. Cook eggs fresh—reheating them ruins the perfect yolk texture. For a quick assembly, keep avocado mash refrigerated and toast bread just before serving.
What's the secret to getting that perfect crispy toast?
Preheat your oven to 375°F and use day-old bread for maximum crispiness. Arrange slices 1 inch apart on a baking sheet and drizzle with just enough olive oil to coat. Toast for 8-10 minutes until edges are golden—this creates the ideal crunch to hold up to the creamy toppings.
