Poached eggs on toast with perfectly runny yolks over crispy bread is a high protein, healthy breakfast classic. This clean eats favorite is simple, satisfying, and a family morning staple.
Fill a wide saucepan with 3 inches of water and bring to a gentle simmer over medium heat; do not allow it to boil.
Add the white vinegar and salt to the water, then use a spoon to create a gentle whirlpool for even cooking.
Crack each egg into a small bowl, then gently slide each egg into the simmering water, spacing them apart.
Poach eggs for 3–4 minutes, maintaining gentle heat, until whites are set and yolks remain runny.
While eggs poach, toast the sourdough slices until golden and crispy; remove and set aside.
Lift each poached egg with a slotted spoon, let excess water drain, then place over toast slices; garnish with black pepper and serve immediately.
