Sourdough Breakfast Toast: The 1 Way to Make It

I used to think avocado toast was a scam. You know the kind. You pay twelve bucks for a plate that looks like it was styled by an influencer who has never actually eaten in their life. Just one sad slice of pale bread, a smear of green, and a sad little egg that’s been sitting under a heat lamp since 9 AM.

Then I started baking my own sourdough. And everything changed.

There is a specific kind of magic that happens when you take a slice of properly fermented, crusty sourdough toast and pair it with ripe avocado and a perfectly poached egg. It’s not just breakfast. It’s a moment. It’s quiet. It’s rich. It’s the kind of meal that makes you actually want to stay in bed a little longer (okay, maybe just sit at the table for ten extra minutes).

I’ve made this sourdough breakfast toast with avocado and poached egg better than takeout more times than I can count. And here’s the secret: it’s stupidly simple. You really can’t mess this up. If you can boil water and mash an avocado, you can make this. It’s forgiving. It’s minimal. It’s just three ingredients working together to create something that tastes like you spent hours in the kitchen (but you didn’t).

This is the one dish I make when I want to feel fancy but don’t want to deal with a complicated recipe. It’s the “if you can only make one thing, make this” breakfast. No stress. No weird techniques. Just good bread, good fats, and a runny yolk that breaks over everything else. Let me show you how to do it right.

Why You’ll Love This Sourdough Breakfast Toast

Look, I’m not trying to convince you that toast is the most exciting food group. But this specific combination? It hits different. Here’s why this sourdough breakfast toast has taken over my morning routine, and why it’s going to take over yours too.

• The Bread Does the Heavy Lifting — Store-bought sandwich bread is soft and sweet. It falls apart under the weight of an egg. Sourdough? It’s sturdy. It has a chew. It has that tangy depth that cuts through the richness of the avocado. Once you try sourdough, you can’t go back. It’s the foundation of everything good.
• The Egg is a Game-Changer — I know, I know. Poaching sounds hard. It sounds like something chefs do with tweezers. But it’s not. It’s just simmering water and patience. When you break that yolk and it runs over the crunchy toast and creamy avocado, it becomes a sauce. A rich, golden sauce. It’s the best part of the meal.
• It’s Actually Healthy (Mostly) — Avocado has fats that are good for you. Eggs have protein. Sourdough is easier to digest than regular bread because of the fermentation. It’s a balanced meal that keeps you full until lunch. No sugar crash. No mid-morning hunger pangs. Just steady energy.
• Minimal Cleanup — This is huge for me. I’m not a fan of washing a dozen pans for breakfast. You need one saucepan for the egg, one skillet or toaster for the bread, and a bowl for the avocado. That’s it. Three dishes. You can handle three dishes.
• It Feels Like a Treat — Even though it’s simple, it feels luxurious. The crunch of the crust, the creaminess of the avocado, the runny yolk. It’s comfort food that doesn’t weigh you down. It’s the kind of breakfast that makes you feel like you’re taking care of yourself.

This is my go-to when I want to start the day right. It’s not rushed. It’s not complicated. It’s just good food that works every single time.

Ingredients You’ll Need

Here’s the best part: you don’t need a fancy grocery run for this. The ingredients are simple, fresh, and likely already in your kitchen or just a quick trip away. I’m particular about three things here: the bread, the avocado, and the eggs. Get those right, and you’re golden.

For the Base

Sourdough Bread (2 thick slices, about 1 inch thick) — This is non-negotiable. I use my own baked loaf, but a good bakery loaf works too. Look for a slice that’s dense and chewy, not airy and fluffy. You need structure to hold the egg. If you don’t have sourdough, a sturdy whole grain or rye works, but sourdough has that unique tang that elevates the whole dish. Slice it thick—half an inch to an inch. Thin slices get soggy fast.

Avocado (1 large, ripe Hass avocado) — This is where you need to be honest with yourself. The avocado needs to be ripe. Not mushy, but not hard. Squeeze it gently; it should yield slightly to pressure. If it’s hard, it’s not ready. If it’s brown inside, toss it. I love Hass avocados because they have that buttery texture and nutty flavor. Green avocados are just too bland. Seasoning later is fine, but the avocado itself needs to be good.

For the Star

Eggs (2 large, fresh eggs) — Freshness matters for poaching. Older eggs have flatter yolks that spread out in the water. Fresh eggs have tighter whites that wrap around the yolk nicely. I buy mine from a local farm stand when I can, but any fresh large eggs work. Room temperature eggs are easier to crack, but cold eggs work fine too. Don’t overthink this.

For the Seasoning

Sea Salt (flaky sea salt, like Maldon) — Regular table salt is fine, but flaky salt on top? That’s the texture you want. It crunches a little and adds bursts of flavor. If you don’t have flaky salt, kosher salt works. Just sprinkle it on at the end.

Freshly Cracked Black Pepper — Generous amount. Pepper adds heat and aroma. Don’t be shy with it.

Red Pepper Flakes (optional, but recommended) — A pinch adds a nice kick. It cuts through the richness of the egg and avocado. I keep a jar of these on the counter specifically for this toast.

Lemon Juice (1 teaspoon) — Just a squeeze over the avocado prevents browning and adds brightness. It wakes up the flavors. Fresh lemon is best. Bottled juice tastes metallic and weird.

Extra Virgin Olive Oil (a drizzle) — For the avocado. Adds fruitiness and richness. I use a good quality oil here. If you have truffle oil, a tiny drop on the egg is fancy, but regular EVOO is perfect.

Microgreens or Chives (optional garnish) — I like the visual pop and the fresh flavor. Chives are easier to find. Microgreens look pretty for Instagram. Both are delicious. Use what you have.

Equipment Needed

You don’t need fancy gadgets for this. Here’s what I actually use. If you don’t have these, you can probably improvise.

Saucepan (6-8 inches wide) — This is for poaching the eggs. You don’t need a giant pot. A small saucepan works best because it concentrates the water depth. I use a 6-inch pan. It makes the water deeper relative to the width, which helps the egg whites wrap around the yolk. If you only have a big pot, it still works, but you might need more water and a bit more care.

Slotted Spoon — To lift the eggs out of the water. A regular spoon works if you’re careful, but a slotted spoon lets the water drain away instantly. I use a metal one. It’s durable and easy to clean.

Skillet or Toaster — For the bread. I prefer a skillet with a little butter or oil because it gets the crust super crispy. But a toaster works too if you’re in a rush. Just be careful with thick sourdough slices in a standard toaster—they might get stuck. I usually use a skillet for control.

Mashing Fork — For the avocado. A fork works perfectly. No need for a special tool.

Small Bowl — For whisking the egg before poaching (optional, but helps). Or just for cracking the egg directly into the water.

Sharp Knife — For slicing the avocado. A dull knife will mash the avocado. Use a sharp one.

Measuring Spoon — For salt and pepper. Or just use your fingers. I’m not judging.

How to Make It: Step-by-Step

Alright, let’s make this! I’m walking you through exactly how I do it. It’s simple, but there are a few tricks to get that perfect runny yolk and crispy bread.

Step 1: Prep the Avocado (2 minutes)

Cut the avocado in half. Scoop out the flesh into a small bowl. Discard the pit (or save it for your garden, if you’re into that). Mash the avocado with a fork. It doesn’t need to be smooth—some chunks are nice for texture. Squeeze in the lemon juice and add a pinch of salt. Mix it well. Set it aside. If you’re not serving immediately, press plastic wrap directly onto the surface of the avocado to prevent browning. But ideally, you’ll assemble this right away.

Step 2: Toast the Sourdough (3-5 minutes)

Heat a skillet over medium heat. Add a small pat of butter or a drizzle of olive oil. Once it’s shimmering, add the sourdough slices. Toast for 2-3 minutes per side until golden brown and crispy. You want that crunch. If your bread is very thick, you might need to cover the pan with a lid for the first minute to help the inside heat up without burning the outside. Remove the toast to a plate. Keep it warm.

Step 3: Prepare the Water for Poaching (2 minutes)

While the bread toasts, fill your saucepan with about 2 inches of water. Bring it to a gentle simmer. Not a rolling boil. You want small bubbles rising from the bottom, but no big splashing. If the water is boiling too hard, the eggs will break apart. If it’s not hot enough, the whites won’t cook. Aim for that sweet spot. Add a splash of white vinegar. This helps the egg whites coagulate faster. Don’t worry, you won’t taste it.

Step 4: Poach the Eggs (3-4 minutes)

Crack each egg into a small ramekin or measuring cup. This makes it easier to slide them into the water without breaking the yolk. One at a time, gently slide the egg into the simmering water. Do this slowly. If you drop it from high up, the yolk might break. Use a spoon to gently swirl the water around the egg. This helps the white wrap around the yolk neatly. Cook for 3-4 minutes. The white should be set, and the yolk should still be soft. If you like a firmer yolk, go for 4-5 minutes. If you like it runnier, 3 minutes is perfect. Use a slotted spoon to lift the egg out. Let the excess water drip off. Place it on a paper towel for a second to dry.

Step 5: Assemble the Toast (1 minute)

Take your toasted sourdough. Spread the mashed avocado generously over the toast. It should be a thick layer. Top with the poached egg. The yolk should be centered. Sprinkle with flaky sea salt, freshly cracked black pepper, and red pepper flakes. Drizzle with a little extra virgin olive oil. Add microgreens or chives if you’re feeling fancy.

Step 6: Serve Immediately

Eat it right away. This is not a make-ahead dish. The bread will get soggy if you wait. The yolk will firm up. The avocado will brown. It’s meant to be eaten hot, fresh, and runny. Cut into it with a knife and fork. Let that yolk flow over everything. Enjoy every bite.

Expert Tips & Tricks

Here’s everything I’ve learned from making this dozens of times. These tips will save you from my mistakes.

Use Fresh Eggs

This is the #1 tip. Fresh eggs hold their shape in the water. Old eggs spread out and look messy. Buy eggs from a store that turns over inventory quickly. If you’re unsure, crack an egg into a bowl first. If the white is thick and tight around the yolk, it’s fresh. If it’s watery and flat, use it for scrambling instead.

Simmer, Don’t Boil

High heat is the enemy of poached eggs. If the water is bubbling violently, the egg will tangle itself into a mess. Keep the heat low. Gentle bubbles only. You can even turn the heat off for the last minute if the water is getting too hot.

The Swirl Method

Swirling the water helps the white wrap around the yolk. It’s not mandatory, but it makes the egg look prettier and more compact. Just swirl gently. Don’t create a whirlpool tornado.

Toast Thick Enough

Thin toast gets soggy. Thick sourdough (at least 3/4 inch) can handle the weight and moisture of the egg and avocado. If your loaf is on the thinner side, toast it longer to make it extra crispy.

Season at the End

Don’t salt the avocado before mashing if you’re serving immediately. It can draw out moisture. Salt it after you’ve spread it on the toast. Same with the pepper. Season right before eating for the best flavor.

Variations & Substitutions

Once you’ve nailed the basic version, here’s how you can mix it up. I’ve tried all of these.

Spicy Avocado Toast

Add a teaspoon of sriracha or chili crisp to the mashed avocado. It adds a nice kick and some color. This is my favorite variation when I want something bold.

Feta and Tomato

Top the avocado with crumbled feta cheese and halved cherry tomatoes. Add a drizzle of balsamic glaze. It’s a bit more Mediterranean, but still delicious.

Smoked Salmon

Skip the egg and add smoked salmon on top of the avocado. Add some cream cheese or goat cheese. This is a bit more decadent, but still simple.

Vegan Version

Skip the egg and use a vegan egg substitute or just extra avocado. Or try tofu scramble on top. The avocado and sourdough are naturally vegan, so it’s easy to adapt.

Different Breads

If you don’t have sourdough, try brioche for a sweeter, richer toast. Or rye for a denser, earthier flavor. Just make sure it’s sturdy enough to hold the toppings.

Serving & Storage

How to Serve:

Serve immediately. This is a fresh dish. Pair it with a cup of coffee or tea. I like a black coffee to balance the richness. Or a glass of orange juice for some acidity.

Side Dishes:

This toast is filling on its own, but you can add a side of fruit or yogurt. A simple green salad works too if you want something lighter.

Storage Instructions:

This dish is best made fresh. The avocado will brown quickly, and the egg will firm up. If you have leftovers (unlikely), store the avocado in an airtight container with plastic wrap on the surface. Re-toast the bread. But honestly, just make fresh batches. It’s worth it.

Reheating:

Don’t reheat the egg. It will become rubbery. Reheat the bread in a toaster or skillet. Make a fresh egg. It’s faster than reheating and tastes better.

Frequently Asked Questions

Can I use store-bought sourdough?

Absolutely. As long as it’s real sourdough (check the ingredients: flour, water, salt, starter. No dough conditioners), it works. Look for a bakery loaf with a thick, crusty exterior. Avoid pre-sliced sandwich-style sourdough; it’s too soft.

Why did my egg whites turn out stringy?

This usually happens if the water is too hot. The whites cook too fast and become rubbery before the yolk is done. Keep the water at a gentle simmer. Also, using older eggs can cause stringy whites. Fresh eggs have tighter whites.

Can I make this ahead for a brunch?

Not really. The avocado browns, and the egg firms up. You can prep the avocado by mashing it and covering it with plastic wrap, but assemble everything right before serving. The bread should be toasted fresh.

What if I don’t have a saucepan for poaching?

You can poach eggs in a microwave, but it’s tricky. Or you can fry them sunny-side up and serve them on top. It’s not traditional, but it’s still delicious. Just be careful not to overcook the yolk.

Can I use regular bread instead of sourdough?

You can, but sourdough is best for its sturdy texture and tangy flavor. If you use regular bread, toast it longer to make it crispy. Thick-cut white bread or whole wheat can work, but you might need more avocado to cover the surface.

How do I know when the egg is done?

After 3 minutes, lift the egg out and check the white. It should be opaque and set. The yolk should still feel soft when you gently press it with a spoon. If you like it firmer, cook for another minute. Remember, the residual heat will continue to cook the yolk slightly after you remove it from the water.
