Few dishes capture the essence of fall as beautifully as Sage Roasted Butternut Squash Soup. With its deep golden color, velvety texture, and earthy aroma, this soup feels like comfort in a bowl. Roasting the squash intensifies its natural sweetness, while fresh sage adds warmth and complexity that elevates the soup beyond ordinary squash recipes.

This soup is simple enough for weeknight dinners yet refined enough to serve as a holiday starter. Unlike boiled squash soups, roasting caramelizes the vegetables, creating layers of flavor that translate into a richer, more satisfying finished dish.

Why Roasting Makes All the Difference

Roasting butternut squash draws out moisture and concentrates flavor. The edges caramelize, adding depth and subtle nuttiness that cannot be achieved through simmering alone. Fresh sage roasted alongside the squash becomes fragrant and slightly crisp, infusing the vegetables with classic autumn flavor.

Ingredients

1 large butternut squash, peeled and cubed
1 medium yellow onion, sliced
3 cloves garlic, smashed
2 tablespoons olive oil
8–10 fresh sage leaves
Salt and black pepper, to taste
4 cups vegetable broth
½ cup heavy cream (or coconut milk)
Optional: pinch of nutmeg

Instructions

Preheat oven to 400°F (205°C).
Spread butternut squash, onion, garlic, and sage leaves on a large baking sheet.
Drizzle with olive oil, season with salt and pepper, and toss to coat evenly.
Roast for 35–40 minutes, turning once, until squash is tender and caramelized.
Transfer roasted vegetables to a large pot and add vegetable broth.
Simmer gently for 10 minutes to meld flavors.
Blend soup until smooth using an immersion blender or countertop blender.
Stir in cream and optional nutmeg. Adjust seasoning to taste.
Serve hot, garnished with crispy sage or olive oil.

Texture and Flavor Profile
