Roasted Acorn Squash Soup With Rosemary and Garlic

The first crisp day of autumn always brings a particular memory to mind. I was visiting my grandmother in upstate New York, and the air was thick with the scent of woodsmoke and fallen leaves. She had a pot of acorn squash soup simmering on the stove, its warmth permeating the entire kitchen. The earthy sweetness of the squash, laced with rosemary and garlic, was pure magic, and it’s a flavor I’ve chased ever since, always trying to recreate that perfect autumn afternoon in a bowl.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 50 minutes
• Total Time: 1 hour 5 minutes
• Servings: 4-6
• Yield: 6-8 cups
• Dietary Type: Vegetarian (can be vegan with substitutions)

Ingredients

• 2 tablespoons clarified butter (ghee) or 2 tablespoons olive oil
• 6 plump garlic cloves, smashed and roughly diced
• 1 1⁄2 cups diced onions (Vidalia is best)
• 3 tablespoons minced fresh rosemary
• 1 teaspoon dried thyme
• 1 teaspoon kosher salt
• 3 cups pre-roasted acorn squash
• 3 cups broth (chicken or vegetable)
• 1 cup milk (dairy or non-dairy alternative)
• Fresh ground pepper to taste
• Cubed gruyere cheese (to garnish, optional)

Equipment Needed

• Large saucepan or Dutch oven
• Baking sheet
• Blender (immersion blender works too)
• Wooden spoon or spatula
• Knife and cutting board

Instructions

1. If you don’t have any pre-roasted squash on hand, begin by preparing the acorn squash: Halve 2 medium to large acorn squash. Scoop out and discard the seeds and stringy bits from the center.
2. Place the squash halves, cut side down, on a baking sheet. Roast them in a preheated oven at 400 degrees Fahrenheit for about 45 minutes, or until the squash is tender when pierced with a fork.
3. Remove the roasted squash from the oven and allow it to cool slightly. Once cool enough to handle, scoop out the flesh from the skin and set aside. You should have about 3 cups of roasted squash.
4. In a deep saucepan or Dutch oven, heat the ghee (or olive oil) over medium heat.
5. Once the ghee or oil is warm, add the diced onions, 4 of the diced garlic cloves, minced fresh rosemary, dried thyme, and salt.
6. Cook the mixture gently until the onions become translucent and just begin to caramelize, about 8-10 minutes. Stir occasionally to prevent burning. The aromatic fragrance of the herbs and garlic will fill your kitchen.
7. Add the scooped out, pre-roasted acorn squash to the pot. Gently mash the squash with a wooden spoon until it is softened, broken up, and fully incorporated with the onion, garlic, and herbs. Don’t worry about getting it perfectly smooth at this stage.
8. Cook this mixture over medium heat for about 5 minutes, stirring frequently, until the squash is bubbling slightly.
9. Add the remaining 2 diced garlic cloves, the broth (either chicken or vegetable), and the milk.
10. Gently mix all of the ingredients together. If the soup appears too thick, add a little more milk to reach your desired consistency. Adjust seasonings with salt and freshly ground black pepper to taste.
11. Allow the soup to gently simmer for about 5-8 minutes, stirring occasionally, to allow the flavors to meld together.
12. Turn off the heat. Carefully puree approximately half of the soup using a blender or an immersion blender until smooth. If using a standard blender, work in batches to avoid accidents.
13. Add the pureed portion of the soup back into the pot with the remaining chunky portion. Mix thoroughly to combine the textures.
14. Serve the soup piping hot, garnished with little cubes of gruyere cheese (optional) and a sprinkle of fresh rosemary. A swirl of cream or a drizzle of olive oil also adds a beautiful touch.

Expert Tips & Tricks

• Roasting the squash ahead of time makes this soup a breeze to prepare. Roast a batch of squash on the weekend and use it throughout the week for various dishes.
• For a richer flavor, use brown butter instead of ghee or olive oil. Simply cook the butter over medium heat until it turns a nutty brown color, being careful not to burn it.
• If you don’t have fresh rosemary, you can use dried rosemary. However, use about half the amount, as dried herbs have a more concentrated flavor.
• Taste the soup as you go and adjust the seasonings to your liking. Don’t be afraid to add a pinch of red pepper flakes for a little heat.
• To prevent the milk from curdling, especially when using dairy milk, avoid boiling the soup after the milk has been added. Simmering gently is key.

Serving & Storage Suggestions

This roasted acorn squash soup is best served hot, straight from the pot. Garnish with cubed gruyere cheese, a swirl of cream, a drizzle of olive oil, or a sprinkle of fresh rosemary. It pairs beautifully with crusty bread for dipping.

Leftover soup can be stored in an airtight container in the refrigerator for up to 3-4 days. It can also be frozen for up to 2-3 months. To reheat, simply warm the soup on the stovetop over medium heat, or in the microwave. If frozen, thaw the soup in the refrigerator overnight before reheating.

• Maple-Glazed Squash: Before roasting the squash, brush the cut sides with maple syrup for a caramelized sweetness.
• Apple & Squash: Add diced apple to the onion mixture to give a slightly tart and sweet dimension to the flavor.
