Ingredient List

Ciabatta Rolls: The chewy, crunchy texture of ciabatta makes the sandwich feel more substantial. It can hold up to dressing and drippy egg yolk without falling to pieces. If you don’t have any on hand, you could also use sandwich bread. I like to make my ciabatta from scratch, but I’ve made this recipe with store bought ciabattas many times.

Eggs: I use large eggs. I like a fried egg, but a buttery scrambled egg would work well too.

Arugula: Peppery and delicate textured. This leafy green can stand up to bacon, blue cheese, and balsamic.

Bacon: Lends to the flavor of the dressing and the salad. Multiuse ingredients since we’ll use the bacon grease as the oil in the dressing.

Balsamic Vinegar: Deep and sweet enough flavor to cut through the peppery arugula and salty bacon. You can also substitute red wine vinegar.

Blue Cheese: Adds a nice creamy touch and funky flavor that elevates the sandwich from good to craveable. If you don’t like blue cheese, feta will give saltiness, goat cheese gives a tang, or even a slice of cheddar or Swiss on top would be lovely.

Step-by-Step Instructions

Toast the Bread: Slice the ciabatta in half and toast the cut sides until crisp. Set aside.
Cook the Bacon: Heat a skillet over medium heat. Cut the bacon into bite-sized pieces. Add the bacon to the pan, separating it as it cooks. When crisp, transfer the bacon to the bowl with the arugula. Pour the rendered bacon grease into a mason jar or bowl.
Make the Dressing: Let the bacon grease cool for about five minutes. Add Dijon mustard, balsamic vinegar, salt, and black pepper to the jar. Shake for 1 minute to emulsify. Set aside.
Fry the Egg: Return the skillet to medium heat. Add a tablespoon of avocado oil. Crack the egg into the pan and season with salt and pepper. Cook for 2 minutes or until the whites are set and the edges begin to crisp. Flip the egg and cook 1-2 minutes more, depending on if you want the yolk runny or set.
Assemble the Sandwich: Toss the arugula with the dressing and blue cheese. Layer onto the bottom half of the ciabatta. Top with the fried egg and top bun.

Expert Tips

When flipping a fried egg, you need the courage of your convictions, as Julia Child would say. Use a thin spatula (a fish spatula is ideal), slide fully under the egg, and flip in one confident motion. Hesitate and the yolk might break, but if it does, don’t panic. It’ll still taste amazing.

If the egg does break, let the white cook for a minute then move it to the ciabatta.

This sandwich is delicious with a runny yolk or a set yolk, but be warned, the runny yolk is messy.

Ciabattas can be tough on the roof of your mouth. Soften the crust first: microwave for 20–30 seconds before slicing, then toast the cut side only for that perfect crunch without the shrapnel. A buttered skillet also works beautifully. Toast for 3-5 minutes.

Putting the arugula on the bottom allows the egg yolk to drip into it and mix the rich yolk with the tart dressing. It also keeps the bottom bun from getting soggy.

What to Serve with a Fried Egg Sandwich

I like something light and fresh to counterbalance the richness of the sandwich. Fresh fruit like grapes, cantaloupe, or strawberries are favorites around my house.

Storage

This isn’t the kind of recipe you can store. The dressing can be refrigerated, but everything else needs to be made fresh. Luckily it’s quick.

If you want to make the components and store them separately for lunch, you could. Just assemble when you’re ready to eat.

FAQs

What’s the best way to keep ciabatta from tearing my gums apart?

Warm it slightly before slicing to soften the crust, then toast the cut sides only. I microwave my ciabatta for about 20 seconds before slicing and use a toaster oven to crisp the inside.

How do I keep arugula from wilting when I add warm bacon and dressing?

Toss the arugula with dressing right before assembling. You can even chill the greens for a few minutes beforehand if you’re worried about it getting soggy.

What’s the best way to flip a fried egg without breaking the yolk?

Use a wide, thin spatula (think fish spatula), gently nudge under the whites first, and flip confidently in one swift motion. Hesitation can lead to exploding yolks.

What if my yolk breaks while cooking?

Let the white firm up, then transfer it carefully. It may not be runny, but it’ll still be rich and tasty.

What if my bacon is lean and doesn’t render enough fat for dressing?

Top it off with a bit of oil or butter. You want about 2 tablespoons of fat for a proper emulsified dressing.

Make this tonight when you’re craving something fast, cozy, and just a little indulgent. Then tell me, did you go with the runny yolk or play it safe?
