1. Using a good knife, cut the butternut squash into approximately 3 cm cubes, and then peel the pieces (it's easier in this order). Steam the pieces for 5 minutes or cook them in a small amount of unsalted water. The pieces should be tender, but not falling apart.
2. While the squash is cooking, roughly chop the smoked bacon (or cut it into very small pieces).
3. Arrange the pieces of squash and bacon in a gratin dish, gently mixing them together (if the squash gets slightly mashed, it's not a problem).
Sprinkle with chopped herbs and pine nuts to your liking.
4. Season with nutmeg and pepper. Lightly salt, as the smoked bacon is already salty (personally, I don't add any salt, but I use plenty of nutmeg). Pour a dash of heavy cream (approximately 5 cl), and finish by sprinkling grated Parmesan cheese on top.
5. Bake for about 20 minutes in a preheated oven at 210°C.
6. Serve hot, accompanied by a green salad.
