Mushroom & Swiss Cheese Frittata
Buttery mushrooms and nutty Swiss folded into a set, golden frittata. Great for brunch and even better cold from the fridge at midnight.

Frittatas are a dependable meal when the fridge is nearly empty. Eggs, cheese, whatever vegetable is going soft — it tends to work every time.
This one leans classic: mushrooms sweated in butter until they're deeply golden, and Swiss cheese for that nutty, melty finish. It sits nicely next to the veggie breakfast hash for a proper brunch spread.
Ingredients
- 8 large eggs
- ¼ cup (60ml) whole milk
- Salt and pepper
- 2 tablespoons butter
- 300g cremini or button mushrooms, sliced
- 2 cloves garlic, minced
- 1 tablespoon fresh thyme leaves
- 1 cup (100g) grated Swiss or Gruyère cheese
- 2 tablespoons chopped chives
Instructions
- Heat the oven to 190°C (375°F).
- Whisk the eggs, milk, salt and pepper in a large bowl.
- Melt the butter in a 10-inch oven-safe skillet over medium heat. Add the mushrooms and cook, stirring occasionally, for 6–8 minutes until deeply golden and any liquid has evaporated.
- Stir in the garlic and thyme, cook 30 seconds, then pour in the eggs. Sprinkle the cheese over the top.
- Cook undisturbed for 3 minutes until the edges start to set, then transfer to the oven.
- Bake 12–14 minutes until just set in the middle. Scatter with chives, slice into wedges and serve.
Cooking tips
- Don't over-salt the eggs before cooking — the cheese adds plenty.
- Let the mushrooms brown properly. Crowding the pan gives you steamed, watery frittata.
- Leftovers keep 3 days and reheat gently in a low oven, or eat cold with a green salad.
