Ingredients:
- 1 large Butternut Squash (approx. 1.2 kg / 2.6 lbs)
- 1 tbsp (15 ml) Olive Oil (or neutral cooking oil)
- 1 tsp (5 g) Fine Sea Salt
- ½ tsp (2.5 g) Freshly Ground Black Pepper
- 8 tbsp (113 g) Unsalted Butter (6 tbsp for brown butter, 2 tbsp for sautéing)
- 1 large Shallot (or ½ small onion), finely diced
- 10 large Fresh Sage Leaves
- 1 tsp (5 ml) Fresh Thyme Leaves (stripped from the stem)
- 3 oz (85 g) Gruyère Cheese, grated (or sharp Cheddar)
- ¼ cup (60 ml) Double Cream (Heavy Cream) or whole milk
- 1 tbsp (15 ml) Maple Syrup (or honey)
- Pinch of Nutmeg (freshly grated is best)
- Salt and Black Pepper, to taste
Instructions:
- Preheat the oven to 200°C (400°F). Line a large baking sheet with parchment paper or foil.
- Using a sharp, stable knife, carefully cut the butternut squash in half lengthwise from the stem to the base. Scoop out and discard the seeds and stringy bits.
- Drizzle the cut sides of the squash with olive oil, salt, and pepper. Place the squash cut-side down on the prepared baking sheet.
- Roast for 45–60 minutes, or until the flesh is fork-tender. Remove and let cool for 15 minutes until they are safe to handle.
- Once cool, gently scoop the cooked flesh out of the squash, leaving about a 1 cm (½ inch) border around the edges to maintain the shells' structural integrity. Place the scooped flesh into a large mixing bowl.
- Make the Crispy Sage: Heat 2 tbsp of butter in a small saucepan over medium heat. When shimmering, add the sage leaves. Fry for 30–60 seconds until they are dark green and crisp. Remove sage with a slotted spoon and drain on kitchen paper. Reserve the infused butter.
- Sauté Aromatics: Add the diced shallot and thyme to the reserved sage butter (add a splash more oil if needed). Sauté for 3–5 minutes until soft and translucent. Add the softened shallots to the bowl with the squash flesh.
- Brown the Butter: In the same saucepan, melt the remaining 6 tbsp of butter over medium heat. Cook, swirling constantly, until the foam subsides and the milk solids turn a deep amber colour and smell nutty. Immediately pour the brown butter (solids and all) over the squash mixture.
- Combine Filling: Add the grated Gruyère, cream, maple syrup, nutmeg, salt, and pepper to the bowl. Use a potato masher or fork to lightly mash the mixture until creamy but still retaining some texture. Taste and adjust seasoning.
- Stuff the Shells: Carefully spoon the filling back into the two squash boats, mounding it slightly above the rim.
- Second Bake: Return the stuffed squash to the oven (still 200°C / 400°F). Bake for 15–20 minutes, or until the filling is piping hot and the cheese topping is golden and bubbling.
- Garnish and Serve: Remove from the oven. Crumble the crispy sage leaves over the top just before serving.
