Step 1: Brown the Mushrooms Properly

Heat olive oil or butter in a non-stick pan over medium-high heat.

Add mushrooms in a single layer and cook without stirring for 2–3 minutes to allow browning.

Stir and continue cooking until golden and the moisture has evaporated.

Season lightly and remove from the pan.

Proper browning prevents a watery omelette.

Step 2: Prepare the Egg Mixture

Crack eggs into a bowl.

Whisk gently with a pinch of salt and pepper. Do not over-whisk — too much air can make the omelette dry.

Add milk if using for a softer finish.

Step 3: Cook the Omelette Gently

Lower heat to medium-low.

Add a small amount of butter or oil to the pan.

Pour in eggs and allow them to settle for a few seconds.

Using a spatula, gently push the edges toward the centre while tilting the pan so uncooked egg flows underneath.

Cook until the top is slightly set but still soft.

Step 4: Add Mushrooms and Fold

Scatter cooked mushrooms over one half of the omelette.

Sprinkle parsley or cheese if using.

Fold the omelette gently over the filling.

Cook for another 30–60 seconds until just set.

Step 5: Serve Immediately

Slide onto a plate and serve while soft and warm.

The centre should remain tender, not dry.
