Instructions

Step 1: Whisk the Eggs

In a medium bowl, crack three large eggs. Add milk if desired, along with a pinch of salt and black pepper. Whisk until the eggs are well combined and slightly frothy. The milk adds creaminess and volume, but you can omit it for a richer, denser omelette.

Step 2: Cook the Vegetables

Heat olive oil or butter in a nonstick pan over medium heat. Add the sliced mushrooms and cook for 3–4 minutes, stirring occasionally, until they are golden brown and have released their moisture. Add the spinach and sauté for another 1–2 minutes until just wilted. Remove some of the spinach and mushroom mixture from the pan to use later as a garnish, if desired.

Step 3: Cook the Omelette

Reduce heat to medium-low. Pour the egg mixture into the pan, tilting it gently so it spreads evenly. Let it cook undisturbed for 1–2 minutes until the edges begin to set. Use a spatula to gently lift the edges and tilt the pan, letting uncooked egg flow underneath.

Step 4: Fold the Omelette

Once the omelette is mostly set but still slightly soft in the center, fold it carefully in half. Cook for another 1–2 minutes until the outside is golden and the inside is fluffy.

Step 5: Plate and Garnish

Slide the omelette onto a plate. Arrange avocado slices and cherry tomatoes alongside the omelette or on top for extra color. Sprinkle with sesame seeds and garnish with fresh herbs. Serve immediately.

Pro Tips for Success

• Use a nonstick pan for easy folding and release.

• Cook over medium-low heat to prevent the eggs from browning too much.

• Don’t overcook—remove from the heat while the center is still slightly soft; the residual heat will finish the job.

• Slice avocado and tomatoes fresh before serving to keep them vibrant and flavorful.

• Garnish generously—it makes the dish feel restaurant-quality.

Storage & Reheating

• Refrigerator: Store leftover omelette in an airtight container for up to 2 days.
