Instructions

Preheat Oven: Preheat the oven to 350F.
Prep the Fennel: Prepare the fennel bulbs. Remove the stalks, cut the bulbs in half lengthwise, then remove the core. Slice the bulbs into thin strips.
Cook the Fennel: Heat the butter and oil in a large skillet over medium-low heat. Add the fennel and onion to the skillet and season with 1/4 tsp each salt and pepper. Cook, stirring occasionally, for 15 minutes until the fennel and onion soften and slightly browned.
Add the Wine: Increase the heat to medium-high. Stir in the garlic and cook for 30 seconds, until aromatic. Add the wine and let it bubble (while stirring) for 1-2 minutes until mostly evaporated. Remove the skillet from the heat.
Combine Ingredients: Toss the sliced potatoes in a large bowl with the remaining salt and pepper, cream, nutmeg, and 1 1/2 cups of the Gruyere. Stir in the fennel and onion mixture.
Assemble: Pour the contents of the bowl into a shallow baking dish, and use a spatula to spread everything around evenly. Top with the remaining Gruyere.
Bake: Bake for 80-90 minutes, or until the potatoes are tender and the top is browned.
