5 Best Omelette Fillings for a Healthy Start

Omelettes are one of the quickest, easiest and most nutritious meals you can make – not just for breakfast, but for any time of day. Packed with protein and incredibly versatile, omelettes allow you to add a range of fillings depending on your tastes, goals, and what you’ve got in the fridge.

Here are my five favourite healthy omelette fillings – all simple, full of flavour, and ideal for anyone looking to eat well without spending ages in the kitchen.

1. Spinach, Mushroom and Feta

A classic combination that ticks all the boxes. Spinach is rich in iron and antioxidants, mushrooms are a great source of B vitamins, and feta adds a creamy, tangy twist without overpowering the other flavours. Gently sauté the mushrooms and spinach first to remove excess moisture before adding to your omelette.

2. Smoked Salmon and Cream Cheese

Perfect for a weekend brunch or a post-workout meal. Smoked salmon brings in protein and omega-3 fatty acids, while a light spread of cream cheese gives it a smooth texture. Add a sprinkle of fresh dill or a squeeze of lemon juice for a fresh finish.

3. Tomato, Red Onion and Cheddar

For a simple, hearty option, combine juicy cherry tomatoes, finely sliced red onion and a little mature cheddar. The cheese adds richness while the vegetables keep it light and full of flavour. Great served with a side of rocket or mixed leaves.

4. Peppers, Black Beans and Avocado

For a more filling and fibre-rich omelette, go for this Mexican-inspired combo. Sautéed peppers and black beans add texture and plant-based protein, while fresh avocado on top brings a creamy finish and healthy fats. Sprinkle with chilli flakes if you like a little heat.

5. Ham, Spinach and Mozzarella

Lean ham pairs beautifully with wilted spinach and shredded mozzarella. This filling is high in protein and iron, and works well as a post-training recovery meal. For extra flavour, add a pinch of mixed herbs or a dash of English mustard.

Tips for the Perfect Omelette

Use 2–3 eggs for a single serving.
Whisk eggs with a splash of milk or water for a fluffier texture.
Cook over a medium heat to avoid burning the bottom while the top remains undercooked.
Always pre-cook watery vegetables like mushrooms or spinach to avoid a soggy omelette.
Fold gently and serve with a fresh side salad for a balanced meal.

Omelettes are a brilliant way to make a fast, healthy meal with minimal fuss. They’re great for meal prep too – just keep the fillings simple and reheat gently.
