Welcome to the ultimate guide for making the perfect sourdough avocado toast with egg. If you’ve been searching for a breakfast that is simple, satisfying, and endlessly customizable, you’ve found it. This isn’t just a recipe; it’s a method for achieving a cafe-quality meal in your own kitchen. We’ll cover everything from picking the perfect ingredients to mastering the cooking technique for a flawless result every single time.
Why This is the Best Sourdough Avocado Toast Recipe
What sets this recipe apart is its focus on the quality and preparation of each component. We don’t just throw things together. We celebrate the tangy crust of perfectly toasted sourdough, the rich creaminess of a seasoned avocado, and the show-stopping perfection of a runny egg yolk. It’s a simple dish, but the details make all the difference, transforming it from a quick snack into a truly memorable meal.
The Three Core Components
Mastering this dish comes down to perfecting its three key elements. When each part is given proper attention, the final result is breakfast perfection.
1. The Sourdough Bread
Sourdough is the ideal foundation. Its sturdy, chewy texture holds up to the toppings without becoming soggy, and its subtle tangy flavor beautifully complements the richness of the avocado and egg. Look for a loaf with a thick, golden-brown crust and an open crumb.
2. The Perfect Avocado
Your avocado should be ripe but still firm. To check, gently press near the stem; it should yield slightly. This ensures a creamy texture that’s easy to smash but not mushy or brown. How you prepare it—smashed with seasonings or elegantly sliced—is up to you.
3. The Flawless Egg
The crowning glory of your toast is the egg. A perfectly cooked egg with a runny yolk creates a rich, savory sauce that ties everything together. While a fried egg is a quick and classic choice, a poached egg offers a touch of elegance. We’ll show you how to master both.
Ingredients You’ll Need
- Sourdough Bread: One thick slice, about 1-inch thick, from a good quality artisan loaf.
- Avocado: Half of a large, ripe Hass avocado.
- Egg: One large, fresh free-range egg. Fresher eggs hold their shape better, especially for poaching.
- Lemon Juice: A small squeeze to brighten the avocado and prevent browning.
- Seasonings: Flaky sea salt and freshly cracked black pepper.
- Optional Garnish: Red pepper flakes for a touch of heat.

How to Make Sourdough Avocado Toast with Egg (Step-by-Step)
The beauty of this recipe lies in its simplicity and the quality of its execution. We’ll cover the two most popular methods for preparing the egg.
Method 1: The Perfect Sunny-Side-Up Fried Egg
- Toast the Bread: Start by toasting your slice of sourdough until it’s golden-brown and crisp on the outside but still has a slight chew in the center. You can use a toaster, or for a more rustic result, toast it in a hot pan with a drizzle of olive oil.
- Prepare the Avocado: While the bread is toasting, scoop the flesh of the avocado into a bowl. Add a squeeze of lemon juice, a pinch of salt, and pepper. Gently smash with a fork until it reaches your desired consistency—I prefer it slightly chunky for better texture.
- Fry the Egg: Heat a small non-stick skillet over medium-low heat with a touch of butter or olive oil. Crack the egg into the pan. Cook gently for 2-3 minutes, until the whites are set but the yolk is still runny. For a more set yolk, you can cover the pan for the last minute of cooking.
- Assemble Your Toast: Spread the smashed avocado evenly over your toasted sourdough. Gently slide the fried egg on top. Finish with a sprinkle of flaky sea salt, black pepper, and a pinch of red pepper flakes, if desired. Serve immediately.
Method 2: The Elegant Poached Egg
- Toast & Mash: Follow steps 1 and 2 from the method above to prepare your sourdough and avocado.
- Poach the Egg: Bring a saucepan of water to a gentle simmer (not a rolling boil). Add a splash of vinegar to help the egg white coagulate. Crack your egg into a small ramekin. Create a gentle vortex in the water with a spoon and carefully slide the egg into the center. Cook for 3 minutes for a runny yolk.
- Assemble: Remove the poached egg with a slotted spoon and let any excess water drain off. Place it carefully atop the avocado-covered sourdough. Season with salt, pepper, and enjoy this elegant twist on the classic sourdough avocado toast with egg.
