Soft-Boiled Egg, Arugula and Parmesan on Focaccia
A simple but elegant Italian breakfast sandwich featuring a runny-yolked soft-boiled egg, peppery arugula, shaved Parmesan, and a drizzle of good olive oil on warm focaccia. The creamy egg yolk acts as a sauce, making each bite luxurious and satisfying.
Steps
Before you start
- Bring a small pot of water to a boil before starting
- Have all ingredients prepped and ready to assemble quickly after the eggs cook
- If your focaccia is not fresh, warm it in a 350°F (175°C) oven for 2 minutes
Boil water and prepare ice bath
- Bring a small pot of water (about 2 quarts/2 L) to a rolling boil over high heat.
- While waiting, fill a bowl with ice water and set it nearby.
- This will stop the eggs from cooking further once they reach the perfect soft-boiled stage.

Ready when: Water at a rolling boil
Tip: Room-temperature eggs cook more evenly than cold ones, reducing the risk of cracked shells.
Soft-boil the eggs
- Gently lower both eggs into the boiling water using a spoon.
- Set a timer for exactly 6 minutes and 30 seconds.
- This timing produces a firm white with a warm, runny yolk—ideal for this sandwich.

Ready when: White is set but yolk is still liquid in the center
Tip: Don't skip the timer—even 30 seconds matters. If you prefer a firmer yolk, add 1 minute; for runnier, subtract 30 seconds.
Stop the cooking process
- When the timer sounds, immediately transfer the eggs to the ice bath using a slotted spoon.
- Let them sit for 2 minutes to halt the cooking.
- They will still be warm and the yolk will remain runny.

Ready when: Eggs are cool enough to handle gently
Tip: Do not skip the ice bath—it locks in the perfectly runny yolk and stops the white from overcooking.
Toast the focaccia
- While the eggs cool, place the focaccia halves cut-side down in a large skillet over medium heat.
- Toast for 2 to 3 minutes until golden and warm, but not hard.
- If the focaccia is very thick, you can tent it with foil and toast 1 minute more.

Ready when: Focaccia is golden brown and warm to touch
Tip: Watch carefully—focaccia can brown quickly. You want it warm and crispy, not burnt.
Assemble the sandwiches
- Place the two focaccia halves on a work surface, cut-side up.
- Divide the arugula evenly between them, piling it loosely.
- Drizzle 1½ teaspoons of olive oil over the arugula on each piece.
- Season the arugula lightly with sea salt and black pepper.

Tip: Don't over-oil at this stage; the egg yolk will provide richness.
Peel and position the eggs
- Gently peel each cooled soft-boiled egg under cool running water, starting at the wider (air pocket) end.
- Place one whole egg on top of the arugula on each sandwich.
- The yolk should be warm and jiggly inside the white.

Ready when: Egg is cleanly peeled and warm
Tip: Handle gently—the yolk is still very soft. If the shell doesn't peel easily, the egg may have stuck to the white, meaning it was slightly overcooked.
Top and serve
- Crown each sandwich with half of the shaved Parmesan.
- Finish with a small drizzle of remaining olive oil (about ½ teaspoon per sandwich), a pinch of sea salt, and a crack of fresh black pepper.
- Serve immediately while the focaccia is still warm.

Tip: Shave the Parmesan just before serving so it doesn't dry out. When you bite into the sandwich, the warm egg yolk will coat the arugula and focaccia beautifully.
Good to know
Tips
- The 6½-minute timer is crucial: 6 minutes gives you a slightly softer yolk; 7 minutes yields a yolk that's mostly set but still warm in the center. Adjust based on your preference and egg size.
- For extra warmth and flavor, brush the toasted focaccia halves with a tiny bit of olive oil or minced garlic before adding the toppings.
- This sandwich is inherently messy—the runny yolk will drip when you bite into it. Eat over a plate and have napkins ready. That's part of the charm.
- If making this for a crowd, you can soft-boil the eggs ahead and keep them in the fridge for up to 1 day, then warm them gently in simmering water for 30 seconds before peeling. The yolk won't be quite as runny, but it still works.
Storage & reheating
Best enjoyed fresh and warm. If you have leftovers, cover and refrigerate the individual components (not assembled) for up to 1 day. To reheat: warm the focaccia in a 350°F (175°C) oven for 2 minutes; refrigerated eggs can be gently rewarmed in simmering water for 30 seconds, but the yolk will be less runny. The sandwich is not recommended for freezing.
Substitutions
- focaccia bread → Ciabatta bread or sourdough. Use slices of similar thickness; ciabatta is slightly denser and sourdough adds tanginess.
- fresh baby arugula → Watercress or young spinach. Watercress is slightly more peppery; spinach is milder. Adjust seasoning accordingly.
- Parmigiano-Reggiano cheese → Pecorino Romano or Grana Padano. Pecorino is sharper and saltier; Grana Padano is slightly milder. Shave thinly either way.
- extra-virgin olive oil → Truffle oil (use less—about half the amount). Adds luxury and earthy depth, but can overwhelm delicate ingredients if overused.
