Steps
Before you start
- Set out the butter 15 minutes ahead so it spreads on bread without tearing it.
- Crack each egg into its own small bowl before heating the pan so you can slide them in gently and avoid broken yolks.
- Have plates and the mayonnaise-spread toast ready, because the eggs are best eaten straight from the pan.
- Use a nonstick or well-seasoned skillet so the eggs release cleanly.
Butter the bread
- Spread the 2 tablespoons (28 g) softened butter evenly over one side of each of the 4 bread slices, going all the way to the edges.

Ready when: Each slice has a thin, even layer of butter with no bare patches.
Tip: Butter to the edges for even browning.
Toast the bread
- Heat the skillet over medium heat for 1 minute.
- Place the bread buttered side down, working in batches if needed.
- Toast 2 to 3 minutes until deep golden.
- Transfer to a cutting board, toasted side down.

Ready when: The bread is deep golden brown and crisp on the buttered side.
Tip: Keep the heat at medium. Higher heat burns the butter before the bread browns.
Spread the mayonnaise
- Spread 1 tablespoon (14 g) mayonnaise on the untoasted side of two slices.
- Leave the other two slices bare for now.
- Wipe out the skillet with a paper towel if any crumbs remain.
Melt the pan butter
- Return the skillet to medium heat and add the 1 tablespoon (14 g) butter.
- Swirl until melted and foaming gently, about 30 seconds.

Ready when: The butter is melted and bubbling softly but has not browned.
Tip: If the butter browns right away, lift the pan off the heat for 15 seconds.
Fry the eggs
- Slide each egg from its bowl into opposite sides of the pan.
- Season with a pinch of salt and pepper.
- Cook 2 minutes until the whites are set and opaque, with the yolks still glossy.

Ready when: The whites are fully opaque with no clear, jiggly areas, and the edges are lightly crisp.
Tip: Slide the eggs in close to the pan surface so the yolks don't break.
Steam and finish
- Cover the pan with the lid, reduce the heat to low, and cook 1 minute for a jammy yolk, or 2 minutes for a fully set yolk.
- The steam sets the whites on top without flipping.

Ready when: For a jammy yolk, a thin white film covers the yolk and it still wobbles when the pan is nudged. For a firm yolk, it looks matte and does not move.
Tip: Don't leave the lid on longer than 2 minutes or the yolks will turn chalky.
Assemble the sandwiches
- Slide a spatula under each egg and place it on a mayonnaise-covered slice.
- Add a little more pepper if you like.
- Top with the remaining toast, toasted side facing out.

Ready when: Each egg sits fully on the bread and the top slice rests flat.
Tip: If an egg is wider than the bread, fold the overhanging white in or trim it with the spatula edge.
Slice and serve
- Cut each sandwich in half diagonally with a sharp knife and serve immediately while the yolk is warm and the toast is crisp.

Ready when: The yolk is soft and the toast is still crisp.
Tip: Eat straight away. The toast softens as it sits.
Good to know
Tips
- Medium heat with a lid gives tender whites and a runny-to-jammy yolk without flipping.
- Use eggs that are as fresh as possible, since their whites stay compact and don't spread thin in the pan.
- Add a slice of cheese on the egg in the last 30 seconds under the lid for a melty version.
- For safe food handling, cook the yolk fully if serving young children, older adults, pregnant people, or anyone with a weakened immune system.
Make ahead
Soften the butter and crack the eggs into bowls up to 15 minutes ahead. The sandwich itself is best assembled and eaten right away.
Storage & reheating
Best eaten immediately. Leftover assembled sandwiches keep in the fridge, wrapped, for up to 1 day. Reheat in a 350°F (175°C) oven or toaster oven for 8 to 10 minutes. The yolk will cook through. Do not freeze. Leave the room-temperature time to no more than 2 hours.
Substitutions
- white sandwich bread → sourdough, brioche, or English muffins. Brioche browns faster, so toast it over medium-low heat.
- mayonnaise → Dijon mustard or hot sauce. Use 1 teaspoon per sandwich for stronger flavor.
- unsalted butter → mayonnaise. Spread a thin layer on the outside of the bread for an extra-crisp, golden toast.
- unsalted butter → neutral oil such as canola. Use 1 tablespoon (15 ml). The eggs will be slightly less rich.
