Ingredients
- 4 large onions
- 200 ml heavy cream
- 100 g grated Gruyère cheese
- 100 ml dry white wine
- 30 g butter
- 1 tbsp olive oil
- 4 fresh thyme sprigs
- 0 to taste salt
- 0 to taste black pepper
Directions
Step 1
Preheat your oven to 180°C (350°F).
Step 2
Peel the onions, leaving them whole, and trim the roots slightly but ensure the base stays intact to hold the onion together.
Step 3
Bring a large pot of salted water to a boil, and blanch the onions for 5 minutes. Drain and set aside to cool slightly.
Step 4
Heat the butter and olive oil in a large, oven-safe skillet over medium heat. Add the blanched onions and cook for 5-7 minutes, turning occasionally, until they begin to brown on the outside.
Step 5
Pour the white wine into the skillet, allowing it to simmer for a minute or two to reduce slightly.
Step 6
Add the heavy cream and thyme sprigs to the skillet, gently stirring to combine. Season with salt and black pepper to taste.
Step 7
Transfer the skillet to the preheated oven and bake for 30 minutes, basting the onions with the cream mixture every 10 minutes.
Step 8
Remove the skillet from the oven and sprinkle the Gruyère cheese evenly over the onions. Return the skillet to the oven and bake for an additional 15 minutes, or until the cheese is melted and golden brown.
Step 9
Discard the thyme sprigs. Serve the onions hot, spooning the creamy sauce over the top.
