Step 1: Spread a generous tablespoon or two of pesto directly into a non-stick frying pan over medium-low heat. Let it warm up for about 30 seconds until fragrant and slightly bubbly. The oil in the pesto will act as your cooking fat.
Step 2: Carefully crack one large egg directly into the center of the warm pesto. The pesto will bubble gently around the egg white, creating a flavorful base.
Step 3: Cook the egg, undisturbed, for 3-5 minutes, or until the egg whites are fully set and the edges of the pesto are visibly crispy and slightly browned. The yolk should still be wonderfully runny. For firmer whites, you can cover the pan for the last minute of cooking.
Step 4: While the egg is frying, toast your thick slice of sourdough bread to your preferred level of crispness. A golden, crunchy slice works best.
Step 5: Once the pesto fried egg is cooked to your liking, carefully remove it from the pan using a thin spatula, making sure to scoop up all the delicious crispy pesto bits clinging to the egg.
Step 6: Transfer the hot pesto fried egg directly onto your toasted sourdough bread. Season with a pinch of salt and freshly ground black pepper if desired, and add any optional garnishes like red pepper flakes, fresh basil, Parmesan, or avocado.
