📋 Step-by-Step Guide (5 Steps)
Dice the Onion and Tomatoes
Place the half onion flat-side down on the cutting board and finely dice into 1/4-inch pieces. Core the tomatoes and dice them into 1/2-inch cubes, keeping their juices on the board. Set both vegetables aside in separate piles.
- • Evenly diced mound of onions with flat cuts
- • Neatly diced tomato chunks with juices collected on the board
- • Using a dull knife that crushes the tomatoes instead of slicing through the skin
Sauté the Diced Onion
Set the skillet over medium heat and add one tablespoon of oil or butter. Once the fat is shimmering, add the diced onions and stir frequently for 3 to 4 minutes until they turn soft and translucent. Do not let them brown excessively.
- • Onions are glistening, softened, and translucent with slight golden edges
- • Gentle, steady sizzling sound without dark smoke
- • Setting the burner to high heat, scorching the onion edges before softening
Cook Down the Tomatoes
Add the diced tomatoes and their juices into the pan with the sautéed onions. Season with salt and pepper, then stir to combine. Simmer uncovered over medium heat for 4 to 5 minutes, mashing slightly with the spoon until a thick, chunky sauce forms.
- • Tomatoes broken down into a bubbling, thickened chunky sauce
- • Liquid reduced so dragging a spoon across the pan leaves a brief visible trail
- • Leaving the mixture too watery before adding eggs, making the dish soggy
Create Wells and Crack the Eggs
Use your spoon to push the tomato mixture aside and make 3 small hollow wells in the sauce. Crack each egg into a small prep bowl first, then gently slide one egg into each well so the yolks stay intact. Season the egg tops with a light pinch of salt and pepper.
- • Three distinct raw eggs resting securely inside individual sauce wells
- • Egg yolks remain unbroken and centered within the clear egg whites
- • Cracking eggs directly against the hot pan rim, risking broken yolks and shell fragments
Add Cheese, Cover, and Simmer to Finish
Scatter the shredded cheese evenly across the tomato sauce and around the egg whites, leaving yolks partially visible if desired. Cover the skillet tightly with its lid and reduce heat to medium-low. Cook undisturbed for 3 to 5 minutes until egg whites are fully set and cheese is completely melted.
- • Egg whites completely opaque and firm to a gentle pan jiggle
- • Cheese melted, glossy, and bubbling around the eggs with soft yolks
- • Lifting the lid constantly, releasing trapped steam and extending cook time
