The recipe

Oven400°F
Timeabout 1 hour 10 minutes

Ingredients

Contains: wheat, tree nuts (auto-detected from the ingredients and method; we can miss things, so check labels)

Directions

Roast the squash

  1. Preheat oven to 400°F. Cut squash in half lengthwise and scoop out seeds; save seeds for toasting if desired.

  2. Place squash halves cut side down on a large baking sheet with sides. Bake until skins are browned and squash is tender, about 1 hour 10 minutes. Let cool slightly.

Make the soup

  1. Scoop cooked squash from skins and transfer to a large saucepan. Mash well with a potato masher, then stir in broth and 2 cups water.

  2. Bring to a simmer over medium‑low heat, stirring often. Season with salt and pepper and remove from heat. Soup should be as thick as tomato sauce—add up to 1 cup more water to thin if necessary.

  3. If you prefer a finer texture, cool slightly then puree soup in a blender or food processor. Let cool completely, transfer to a container with a lid and refrigerate at least 8 hours.

Fry the sage and croutons

  1. Up to 4 hours before serving, heat 3 tablespoons oil in a medium skillet over medium heat. Add sage leaves and cook until lightly browned, turning once, about 1 minute. Using tongs, transfer sage to paper towels to drain. Reserve oil in skillet.

  2. Trim crusts from bread, discarding crusts. Cut each bread slice diagonally into 4 triangles, then cut each triangle in half to make 32 croutons total.

  3. Heat reserved oil in skillet over medium heat. Add half the croutons and cook, turning once, until golden on both sides, about 1 minute. Transfer to paper towels to drain. Heat remaining 1 tablespoon oil in skillet and cook remaining croutons as before.

Serve

  1. Rewarm soup over low heat, stirring occasionally. Ladle soup into bowls and scatter 3 toasted sage leaves over each portion. Garnish each with 4 croutons and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butternut or acorn squash
Provides the main body, sweetness and smooth thick texture when roasted and mashed.
Vegetable broth
Adds liquid so the mashed squash becomes a pourable soup.
Extra-virgin olive oil
Carries flavor and fries the sage leaves and croutons to a crisp golden finish.
White bread
Fried into croutons that add crunch contrasting with the smooth soup.
Sage leaves
Fried briefly to become crisp and add an aromatic herbal note.

The step that matters

Roasting the squash until skins are browned and flesh is tender. Roasting caramelizes the squash's natural sugars and concentrates flavor, while full tenderness ensures the flesh mashes smoothly without lumps or a raw, starchy taste.
