Viral Creamy Roasted Butternut Squash Soup with Brown Butter and Crispy Sage

Viral Creamy Roasted Butternut Squash Soup with Brown Butter and Crispy Sage

There is a reason this soup is all over Pinterest right now. Roasting the squash until the edges caramelize, then blending it silky-smooth with sweet onion, garlic, and a touch of cream, turns a humble winter vegetable into something that tastes like a holiday restaurant starter. Finished with nutty brown butter and shatteringly crisp sage leaves, it is the kind of bowl that makes a cold evening feel like a celebration.

This is also one of the easiest soups you will ever make. Most of the work happens in the oven while the squash roasts, and a single pot and a blender handle the rest. Serve it as a cozy weeknight dinner with crusty bread, or ladle it into small cups as an elegant first course for your Christmas table.

The secret is in the roast. High heat coaxes out the natural sweetness of the squash and adds deep, toasty notes that boiled squash simply cannot match. A pinch of nutmeg and a splash of maple syrup round out the flavor, while the brown butter and sage on top add the crunch and richness that make every spoonful interesting.

Why You Will Love This Recipe

This soup is velvety, naturally sweet, and deeply comforting without feeling heavy. It comes together with simple pantry ingredients, it is easy to make ahead for holiday entertaining, and it freezes beautifully for busy winter weeks. Best of all, the brown butter and crispy sage topping takes about five minutes and makes the whole dish taste like something special.

Ingredients

• 1 large butternut squash (about 3 pounds), peeled, seeded, and cut into 1-inch cubes
• 1 yellow onion, quartered
• 4 cloves garlic, unpeeled
• 3 tablespoons olive oil
• 1 teaspoon kosher salt, plus more to taste
• 1/2 teaspoon black pepper
• 1/4 teaspoon ground nutmeg
• 4 cups vegetable broth (or chicken broth)
• 1 tablespoon maple syrup
• 1/2 cup heavy cream, plus more for swirling
• 4 tablespoons unsalted butter
• 12 fresh sage leaves
• 2 tablespoons toasted pumpkin seeds (pepitas), for serving

Instructions

1. Preheat the oven to 400°F (200°C) and line a large baking sheet with parchment paper.
2. Toss the squash cubes and onion quarters with the olive oil, salt, pepper, and nutmeg. Spread them in a single layer on the baking sheet and tuck the unpeeled garlic cloves among the vegetables.
3. Roast for 35 to 40 minutes, turning once halfway through, until the squash is tender and caramelized at the edges.
4. Squeeze the soft garlic from its skins into a large pot. Add the roasted squash and onion along with the vegetable broth.
5. Bring to a gentle simmer over medium heat and cook for 5 minutes so the flavors meld.
6. Blend the soup in batches until completely smooth, or use an immersion blender right in the pot. Take care with hot liquid and never fill a blender more than halfway.
7. Stir in the maple syrup and heavy cream. Taste and adjust the salt and pepper. Keep warm over low heat while you make the topping.
8. Melt the butter in a small skillet over medium heat. When it foams and turns golden brown with a nutty aroma, about 2 to 3 minutes, add the sage leaves in a single layer.
9. Fry the sage for 30 to 60 seconds until crisp, then lift the leaves out with a fork. Spoon the brown butter over the leaves or reserve it for drizzling.
10. Ladle the soup into warm bowls. Swirl with a little extra cream, drizzle with brown butter, and top with crispy sage leaves and toasted pumpkin seeds. Serve right away.

Tips for the Best Butternut Squash Soup

Cut the squash into even pieces so it roasts at the same rate, and do not crowd the pan, or it will steam instead of caramelizing. For the silkiest texture, blend a full minute longer than you think you need to, then pass the soup through a fine strainer if you want it extra smooth. If the soup feels too thick, thin it with a splash of warm broth until it coats the back of a spoon.

Short on time? Use pre-cut butternut squash from the produce aisle and skip the peeling entirely. Want a dairy-free version? Swap the cream for full-fat coconut milk and brown a little olive oil with the sage instead of butter.

Make-Ahead and Storage

This soup tastes even better the next day, so it is perfect for holiday prep. Cool it completely, then refrigerate in an airtight container for up to 4 days. Reheat gently over low heat, adding a splash of broth if it has thickened. To freeze, leave out the cream, cool, and freeze for up to 3 months; stir the cream in while reheating. Make the brown butter and crispy sage fresh just before serving so the leaves stay crisp.
