01 - In a large mixing bowl, lightly whisk the eggs with milk or cream, salt, and pepper until fully blended.
02 - Gently fold in the potato chips, ensuring they soak for 2 to 3 minutes until softened but retain slight crunch.
03 - If using, mix in the chopped shallot and parsley for additional freshness.
04 - Warm olive oil in a nonstick skillet, approximately 8 inches in diameter, set over medium heat.
05 - Pour the egg and chip mixture into the skillet. Allow to cook undisturbed for 2 to 3 minutes until edges begin to set firmly.
06 - Using a spatula, gently lift the edges and tilt the pan to let uncooked egg flow beneath for even setting.
07 - Once the center is mostly set yet slightly runny (after about 5 to 6 minutes), invert the omelet using a plate or spatula and return to the skillet for 1 to 2 more minutes until golden and fully cooked.
08 - Transfer onto a plate, slice, and serve immediately while warm.
