Method

You’ll need: oven · frying pan · chopping board · knife · grater

1. Preheat the oven to 200 °C (180 °C fan). Trim and halve the Brussels sprouts and slice the shallots into strips.
2. Fry the Brussels sprouts and shallots in the butter in an ovenproof frying pan for 6–8 minutes, until the sprouts take on colour.
3. Grate the Alpine cheese. Whisk the eggs, cream, half the Alpine cheese, nutmeg, salt, pepper and thyme leaves.
4. Pour the egg mixture over the Brussels sprouts, scatter over the walnuts and the remaining Alpine cheese and let it start to set over a medium heat for 2 minutes.
5. Bake the frittata in the oven at 200 °C for 12–15 minutes, until the middle is firm.
6. Leave the frittata to rest for 5 minutes, cut it into four pieces and serve warm.

Good to know

Brussels sprouts for breakfast? In a frittata, yes: fried, they taste nutty and mild, and Alpine cheese and thyme make them festive. The pan goes from the hob into the oven and onto the table for cutting.

Swaps

Alpine cheese → Gruyère or parmesan. Cream → milk (then no longer keto). Walnuts → hazelnuts. Thyme → marjoram.

Cooking tips

Fry the sprouts cut side down so they get roasted flavours. The frittata is done when the middle no longer wobbles when you shake the pan.

Storage

Keeps for 3 days covered in the fridge; tastes good cold too.

Allergens

Contains egg, milk and walnuts; gluten-free. Suitable during pregnancy if the frittata is fully set.
