• Eggs – 6

Step-by-Step Recipe

Creating the perfect potato and onion omelette is about patience and technique. The key is to cook the ingredients gently to ensure the flavors blend harmoniously. Let’s walk through the steps of making this delicious dish.

Step 1: Preparing the Potatoes and Onions

1. Peel the potatoes and cut them into thin, even slices or small cubes for faster cooking.
2. Slice the onion thinly to match the size of the potatoes.

Step 2: Cooking the Potatoes and Onions

1. Heat olive oil in a non-stick pan over medium heat.
2. Add the potatoes and onions, seasoning with salt and pepper. Cook them gently, stirring occasionally to ensure they don’t brown too much.
3. Cover the pan and let the mixture cook for 15-20 minutes, or until the potatoes are soft and the onions are translucent. The goal is to soften the ingredients without turning them crispy.

Step 3: Whisking the Eggs

1. While the potatoes and onions are cooking, crack the eggs into a large bowl and whisk them until smooth.
2. Add a pinch of salt and pepper to the eggs for seasoning.

Step 4: Combining the Mixture

1. Once the potatoes and onions are fully cooked, remove them from the pan using a slotted spoon to drain excess oil.
2. Add the cooked potatoes and onions to the bowl of whisked eggs. Stir gently to combine.

Step 5: Cooking the Omelette

1. Wipe the pan clean and add a small drizzle of olive oil to prevent sticking.
2. Pour the egg mixture back into the pan, spreading it evenly.
3. Cook over low heat for 5-7 minutes, or until the edges start to set but the center is still slightly runny.

Step 6: Flipping the Omelette

1. To flip the omelette, cover the pan with a large plate or flat lid and carefully invert the pan, sliding the omelette back in to cook the other side.
2. Cook for another 3-5 minutes, or until the omelette is fully set and golden on both sides.

Step 7: Serving

1. Transfer the omelette to a plate and let it cool slightly before slicing.
2. Garnish with chopped parsley or herbs if desired. Serve warm or at room temperature.

Variations and Customizations

The potato and onion omelette is a wonderfully adaptable dish. Here are some creative ways to customize it:

1. Cheese-Lovers' Omelette: Add grated Cheddar, Mozzarella, or Manchego cheese to the egg mixture for a creamy twist.
2. Meaty Version: Incorporate chorizo, ham, or bacon for a heartier meal.
3. Vegetable Additions: Toss in extra vegetables like spinach, bell peppers, or zucchini for added color and nutrition.
