A velvety, comforting soup made with roasted butternut squash, caramelized onions, and crispy sage leaves. This recipe is a love letter to a lost bistro classic, refined through twelve attempts to achieve deep, nutty flavor and silky texture.
Roast the squash until deeply browned for best flavor. Do not skip the nutmeg—it enhances the squash. Season in layers: before roasting, after blending, and before serving. For a vegan version, use coconut oil and full-fat coconut milk. For a spicy twist, add diced jalapeño or red pepper flakes. For an apple variation, add a chopped Granny Smith apple to the roasting pan. For a curried version, stir in 1 tablespoon curry powder after blending. Adjust broth amount for desired thickness (3 cups for thicker, 5 cups for thinner). Soup keeps in the refrigerator for up to 5 days and freezes for up to 3 months. Reheat gently on the stovetop, not in the microwave.
