Step-by-Step Instructions

1

Roast Squash and Aromatics

Preheat oven to 400°F (200°C). Place squash halves cut-side up on a baking sheet, brush with olive oil, and season with salt and pepper. Place unpeeled garlic cloves in the cavity. Roast for 35 to 40 minutes until deeply tender and caramelized.

2

Sauté Onion & Simmer

In a Dutch oven, heat remaining olive oil over medium heat. Sauté chopped onion for 6 minutes until translucent. Squeeze roasted garlic from papery skins and scoop roasted squash flesh directly into the pot.

3

Blend Silky Smooth

Pour in vegetable broth and ground nutmeg. Bring to a gentle simmer for 5 minutes. Use an immersion blender (or high-speed countertop blender) to purée soup until completely silky and velvety. Stir in heavy cream and adjust seasoning.

4

Crisp Sage in Brown Butter

In a small skillet, melt 2 tablespoons butter over medium heat. Once foaming and starting to turn nutty brown, add sage leaves and fry for 45 to 60 seconds until crisp. Remove immediately.

5

Garnish and Serve

Ladle hot soup into bowls. Drizzle with nutty brown butter, top with crispy fried sage leaves, toasted pepitas, and a swirl of cream.
