- Simple ingredients with big, savory flavor
- Light but filling enough for lunch or dinner
- Naturally low in carbs and packed with protein

- Perfect for busy weekdays or relaxed weekends
Ingredients

- 1 teaspoon butter
- 2 chestnut mushrooms, thinly sliced
- 1 handful baby spinach
- 2 large eggs
- 20 g cheddar cheese, grated
- Salt and pepper, to taste
Ingredient Notes and Substitutions
Chestnut mushrooms bring a deep, savory flavor, but white button mushrooms work just as well. Slice them thin so they cook quickly and evenly.
Cheddar adds a rich, familiar taste, though Gruyere or Swiss cheese would be lovely if you want something a little more French-inspired. For a lighter option, use less cheese or skip it entirely.
Fresh spinach wilts down fast. If your handful looks like too much, trust me, it shrinks beautifully once it hits the pan.
Instructions

- Place a small frying pan over medium heat and add the butter. Once melted, add the sliced mushrooms.
- Cook the mushrooms for a couple of minutes on each side until golden. Add the spinach and stir gently until wilted.
- While the vegetables cook, crack the eggs into a cup or small jug. Whisk with a fork, then stir in the grated cheese, salt, and pepper.
- Pour the eggs into the pan and stir briefly to combine with the mushrooms and spinach.
- Let the omelette cook undisturbed until the bottom is golden and the top is almost set.
- Fold the omelette in half and slide it onto a plate. Serve warm.

Pro Tips for Success
- Keep the heat at medium so the eggs cook gently without browning too fast.
- Use a nonstick pan if possible. It makes folding the omelette much easier.
- Whisk the eggs just until blended. Over-whisking can make them tough.
- If the top is slow to set, cover the pan for a moment to trap heat.
Storage and Reheating
This spinach and mushroom omelette is best enjoyed fresh, but leftovers can be stored in the fridge for up to 2 days.
To reheat, warm gently in a pan over low heat or in the microwave for short bursts. The texture stays nicest when reheated slowly.
Make Ahead and Freezing
You can cook the mushrooms and spinach ahead of time and store them in the fridge. When you are ready to eat, simply add them to freshly whisked eggs.
This omelette can be frozen, though the texture of the eggs will be slightly softer once thawed. Freeze fully cooked, wrapped well, and reheat gently.
Tips and Variations
- Add chopped onions or shallots with the mushrooms for extra flavor.
- Swap spinach for kale or arugula.
- Use feta or goat cheese for a tangy twist.
- Sprinkle fresh herbs like chives or parsley before serving.
- Turn it into a heartier meal by adding roasted potatoes on the side.
FAQs
Yes. It is light but filling and pairs well with a salad or bread.
Absolutely. The mushrooms and spinach still give plenty of flavor.
Use a well-heated nonstick pan and enough butter to coat the surface.
