Ingredients
Vegetables
- 1 medium butternut squash, peeled and sliced into thin rounds
- 2 large leeks, white + light green parts only, thinly sliced
- 2 tbsp unsalted butter
- 2 cloves garlic, minced
- 1 tsp fresh thyme (plus extra for garnish)
- Salt & pepper, to taste
Sauce
- 1 cup heavy cream
- ½ cup whole milk
- ½ tsp nutmeg
- ½ tsp Dijon mustard
- Salt & pepper
Cheese
- 1 ½ cups Gruyère, freshly grated
- ½ cup Parmesan, grated (optional but recommended)
Instructions
1. Prepare the squash
- Preheat oven to 375°F (190°C).
- Arrange squash slices on a baking sheet, drizzle with olive oil, season with salt + pepper.
