Ingredients for Acorn Squash Soup

Gathering these simple ingredients is the first step toward making a truly delightful homemade acorn squash soup. The quality of your acorn squash really makes a difference here, so pick two medium ones that feel heavy for their size.

2 medium acorn squash (4 pounds total, halved and seeded) – These are the stars of our show!
2 tablespoons olive oil – To help roast the squash beautifully.
½ teaspoon sea salt – For seasoning the squash before roasting.
⅛ teaspoon black pepper – Just a pinch to enhance the squash flavor.
1 tablespoon olive oil – For sautéing our aromatics.
1 medium onion, chopped – Adds a foundational savory note.
2 medium carrots, chopped – They bring a subtle sweetness and lovely color.
3 cloves garlic, minced – Essential for that deep, aromatic flavor base.
4 cups chicken broth or vegetable broth – Use vegetable broth for a vegetarian option.
1 tablespoon fresh thyme leaves – Thyme adds a wonderful earthy, herbaceous note that complements the squash.
½ cup half and half – This is key for achieving that luxuriously creamy texture in our creamy acorn squash soup.
1½ teaspoons sea salt, or to taste – Crucial for bringing out all the flavors.
¼ teaspoon black pepper, or to taste – For a gentle warmth.
1-2 tablespoons maple syrup, optional – A little drizzle can enhance the natural sweetness if desired.

How to Make Acorn Squash Soup

Making this easy acorn squash soup is a true joy, and the process is quite straightforward. It all starts with coaxing out the best flavor from the squash itself.

Step 1: Preheat your oven to 425°F (218°C). I like to line a baking sheet with parchment paper for easy cleanup. Place the halved acorn squash cut-side up on the sheet. Drizzle them with 2 tablespoons olive oil, then sprinkle with ½ teaspoon sea salt and ⅛ teaspoon black pepper.
Step 2: Flip the squash halves cut-side down onto the prepared baking sheet. Roast for 30-40 minutes. You’ll know they’re ready when the squash is very tender when poked with a fork and the skin looks wonderfully wrinkled and slightly caramelized.
Step 3: While the squash is in the oven, heat 1 tablespoon olive oil in a large Dutch oven or heavy-bottomed pot over medium heat. Add the 1 medium onion, chopped, 2 medium carrots, chopped, and 3 cloves garlic, minced. Cook, stirring occasionally, for about 5 minutes until these aromatics are softened and just beginning to turn golden.
Step 4: Once the squash is tender, carefully scoop the soft, roasted flesh out of the skins. Discard the skins. Add the scooped squash flesh directly into the Dutch oven with the sautéed vegetables. This is where the magic starts to happen for our homemade acorn squash soup.
Step 5: Pour in 4 cups chicken broth or vegetable broth and stir in the 1 tablespoon fresh thyme leaves. Give everything a good stir to combine the squash, vegetables, and broth.
Step 6: Increase the heat to high and bring the soup mixture to a boil. Once boiling, reduce the heat to medium-low, cover the pot, and let it simmer gently for 10 minutes. This simmering time really allows all those delicious flavors to meld together beautifully.
Step 7: Stir in the ½ cup half and half. This is what gives our soup its signature luxurious creaminess. Now, using an immersion blender, carefully blend the soup directly in the pot until it is completely smooth and velvety. If you don’t have an immersion blender, you can transfer the soup in batches to a regular blender (be careful with hot liquids!).
Step 8: Season your beautiful acorn squash soup with 1½ teaspoons sea salt and ¼ teaspoon black pepper. Taste and adjust seasonings as needed. For a touch more sweetness, you can blend in 1-2 tablespoons maple syrup, tasting as you go, until it’s just right for your preference.

Roasting the Acorn Squash

Roasting the acorn squash at 425°F (218°C) for 30-40 minutes is crucial. This high heat caramelizes the natural sugars in the squash, creating a deep, sweet flavor and ensuring the flesh is fork-tender, making it easy to scoop out and blend into a smooth soup. For more information on the benefits of roasting vegetables, check out this guide to roasting vegetables.

Sautéing Aromatics

Sautéing the onion, carrots, and garlic in a tablespoon of olive oil for about 5 minutes builds a foundational layer of savory flavor. This step softens the vegetables and releases their aromatic compounds, which will infuse the entire soup. The nutritional benefits of onions are also a great reason to include them!

Simmering and Blending

After combining all the main ingredients and broth, a 10-minute simmer allows the flavors to meld. Then, blending the soup until completely smooth, especially after adding the half and half, is what creates that wonderfully creamy, velvety texture that makes this soup so comforting.

Seasoning and Sweetening

Seasoning with salt and pepper to taste is essential to bring out the squash’s natural sweetness and the savory notes from the aromatics. The optional maple syrup can be added to enhance sweetness, allowing you to customize the flavor profile to your liking. If you enjoy maple, you might also like our recipe for Buttermilk Pancakes with Maple Syrup Apples.
