1 large butternut squash (about 3 lb)
1 tbsp olive oil
4 tbsp unsalted butter
10 fresh sage leaves
1 tbsp honey Shop
1/2 tsp kosher salt
1/4 tsp black pepper
1 pinch ground nutmeg Shop
2 tbsp toasted pumpkin seeds Shop

Instructions

1 Heat the oven to 400F (200C). Peel the squash, cut off the bulb end, and halve the neck lengthwise (save the bulb for soup). Scoop out any seeds from the neck.
2 Microwave the halves on a plate, covered, for 4 to 5 minutes to soften slightly. Lay each half cut side down between two chopsticks and slice crosswise every 1/8 inch - the chopsticks stop the knife before it cuts through.
3 Set the halves on a parchment-lined baking sheet, brush with olive oil, and season with half the salt and pepper. Roast 30 minutes.
4 Meanwhile, melt the butter in a small pan over medium heat and add the sage. Cook, swirling, until the butter smells nutty and the milk solids turn golden brown, 3 to 4 minutes. Take off the heat and stir in the honey, nutmeg, and remaining salt.
5 Brush half the brown butter over the squash, letting it run between the slices. Roast 25 to 30 minutes more, brushing once more halfway, until a knife slides in easily and the edges are caramelized.
6 Top with the crisp sage leaves and pumpkin seeds and serve.

Tips & Notes

Use only the straight neck of the squash - it slices evenly and holds its accordion shape.
Make it vegan by swapping the butter for olive oil and the honey for maple syrup.
The bulb end makes a great base for butternut squash soup the next day.
