How to Make Butternut Squash Soup with Roasted Garlic

1. Preheat the Oven

Preheat your oven to 425°F (220°C). Line a baking sheet with parchment for easier clean-up.

2. Prep the Veggies

• Cut your butternut squash in half lengthwise and scoop out the seeds.
• Cut the onion in half.
• Slice the top off the garlic head to expose the cloves.

Place all the vegetables on the baking sheet, drizzle with olive oil, and sprinkle generously with salt and pepper.

3. Roast

Roast everything for about 1 hour, or until the squash is fork-tender and the garlic is soft and golden. If the garlic finishes early, just pull it from the oven while the rest roasts.

4. Scoop and Blend

Once cooled slightly:

• Scoop the squash out of its skin.
• Squeeze the roasted garlic cloves out.
• Peel or scoop the roasted onion.

Add them to a blender with 3 cups of broth and cream. Blend until smooth. Add more broth if you want a thinner consistency.

Tip: If using a high-speed blender, work in batches and vent the lid to avoid steam build-up. An immersion blender works too!

5. Heat and Season

Pour the blended soup into a large pot and warm it gently over medium-low heat. Taste and adjust salt, pepper, or consistency as needed.

6. Garnish and Serve

Ladle into bowls and top with any of the following:

• A swirl of cream or olive oil
• Croutons or toasted bread
• Fried sage and brown butter
• Fresh parsley or chives
• Roasted squash seeds

Tips & Variations

• Make it dairy-free: Swap heavy cream for coconut milk, oat milk, or cashew cream.
• Add warming spices: A pinch of cinnamon, nutmeg, or smoked paprika can take it up a notch.
• Want more protein? Add cooked white beans or lentils to the blender.
• Too thick? Stir in more broth or a splash of water.
• Too thin? Let it simmer a few extra minutes uncovered, or stir in a mashed potato or carrot.
