Ingredients You’ll Need
Gather these few essentials, and you’re halfway to a pot of cozy soup heaven:
- Acorn Squash: The star—its sweet, slightly nutty flesh ensures the soup’s base is rich and naturally creamy.
- Yellow Onion: Roasted with the peel on for deeper flavor; don’t forget to remove the peel before blending!
- Garlic Bulb: Roasting brings out its mellow, almost caramelized notes, adding warmth and subtle sweetness.
- Carrots: These sneak in vibrant color and amp up the soup’s natural sweetness.
- Olive Oil: Crucial for roasting—the fat helps everything caramelize beautifully.
- Salt and Black Pepper: The basics for seasoning—taste as you go and adjust as needed.
- Low-Sodium Vegetable Stock: Lets the squash shine while keeping it vegetarian. If you’re in a pinch, even water works, but stock adds depth.
- Bay Leaf: Infuses aromatic, herbal notes without overpowering.
- Sour Cream: Just enough to swirl in tangy creaminess at the end; Greek yogurt can also work for a lighter twist.

Variations
Don’t let what’s in your fridge hold you back—here’s how you can make this soup your own:
Spice It Up: Add a pinch of cayenne or a sprinkle of smoked paprika for a gentle kick.
Dairy-Free: Use unsweetened coconut cream or cashew cream instead of sour cream for a luscious vegan version.
Extra Veggies: Toss in celery or sweet potatoes to roast along with the squash for more depth.
Garnish Glam: Top each bowl with toasted pumpkin seeds, crispy bacon bits, or fresh herbs like chives, dill, or parsley. A drizzle of olive oil or a swirl of extra sour cream is always welcome.
How to Make Acorn Squash Soup
This recipe boils down to three easy phases: roast, simmer, blend, and enjoy.
1. Roast the Vegetables
Begin by heating your oven to 400°F (200°C). Cut your acorn squash in half, scoop out the seeds, and place cut-side up on a baking tray alongside onion halves (yes, peel on!), halved garlic bulb, and carrots. Drizzle everything generously with olive oil and shower with salt and pepper.
Roast uncovered for 20 minutes, then give everything a flip and roast for another 20 to 25 minutes. You’re looking for vegetables that are fork-tender, caramelized at the edges, and utterly fragrant.
2. Simmer the Soup
Once the vegetables have cooled just enough to handle, peel the onion and garlic. Scoop the flesh from the acorn squash. Add all the roasted goodness to your biggest soup pot. Pour in the vegetable stock and tuck in a bay leaf.
Bring it to a gentle simmer for about 10 to 15 minutes—a little time to let those flavors mingle and deepen. Discard the bay leaf when you’re done.
3. Blend Until Smooth
Now comes the fun part: puree everything until silky smooth. A countertop blender works great for ultimate smoothness, but an immersion blender right in the pot keeps clean-up easy.
Stir in the sour cream (this is where the magic happens—the soup becomes luxuriously creamy with a delicate tang). Taste and adjust seasonings if desired. Serve piping hot!
Note: If your soup is thicker than you’d like, just add a splash more stock or water to reach your perfect texture.
Pro Tips for Making the Recipe
- Roast for Flavor: Don’t rush the roasting—caramelized edges on your veggies mean richer, deeper soup.
- Let It Cool: Give your veggies a few minutes to cool before handling. Much easier to peel and less risk of burns.
- Adjust the Texture: For extra-velvety soup, blend in batches and strain through a sieve if you want it ultra-smooth.
- Balance and Brighten: A squeeze of lemon juice right before serving can brighten up the flavors beautifully.
How to Serve
This soup is wonderfully versatile and can be dressed up or down for any occasion.
Garnishes
A dollop of sour cream or Greek yogurt swirled in, a sprinkle of herbs (think fresh thyme or parsley), or crunchy roasted pumpkin seeds for extra texture—choose your favorites!
Pairings
Serve with crusty bread, a grilled cheese, or a simple green salad for a satisfying meal. It’s also a lovely starter course for an autumn dinner party.
Make Ahead and Storage
Storing Leftovers
Cool the soup completely before transferring it to an airtight container. It keeps well in the refrigerator for up to four days. The flavors only get better as it sits!
Freezing
This soup freezes beautifully. Portion into freezer-safe containers or bags, leaving space for expansion. Freeze for up to three months.
Reheating
Reheat gently on the stovetop or in the microwave, stirring occasionally. If the soup has thickened too much, just loosen with a splash of water or stock as it warms up.
FAQs
-
Can I use butternut squash instead of acorn squash?
Absolutely! Butternut squash will make the soup even creamier and slightly sweeter. Just roast as you would the acorn squash.
-
Do I need to peel the squash before roasting?
No need! Roast the squash halves with the skin on, then simply scoop out the flesh once they’re tender—mess-free and faster.
-
Is it possible to make this soup entirely vegan?
Definitely. Swap the sour cream for coconut cream, cashew cream, or any plant-based alternative and skip any dairy toppings.
-
How can I thicken or thin out the soup?
If your soup is too thick after blending, just stir in more stock or water, a little at a time, until it’s just right. If it’s too thin, let it simmer uncovered for a few more minutes to reduce.
Final Thoughts

Ingredients
Vegetables
- 2 acorn squash (2.5–3 lb total)
- 1 medium yellow onion, sliced in half, peel on
- 1 garlic bulb, sliced lengthwise, peel on
- 2 medium carrots, peeled
Seasonings & Fats
- 1 tablespoon olive oil
- 1/2 teaspoon salt
- 1/4 teaspoon ground black pepper
- 1 bay leaf
Liquids & Dairy
- 4 cups (1 liter) low-sodium vegetable stock
- 1/4 cup sour cream
Instructions
- Preheat the oven. Preheat your oven to 400°F (200°C), or 180°C for a fan oven, preparing for roasting the vegetables which brings out their natural sweetness.
- Prepare and season the vegetables. Arrange the acorn squash halves, onion halves, garlic bulb, and peeled carrots on a baking sheet. Drizzle them evenly with olive oil and sprinkle with salt and black pepper.
- Roast the vegetables. Place the baking sheet in the oven with the vegetables cut side up. Roast for 20 minutes, then flip the vegetables and roast for an additional 20-25 minutes, or until all are fork-tender and caramelized.
- Remove skins and prep the squash. Once cool enough to handle, remove the peels from the onion and garlic. Scoop the roasted flesh out of the acorn squash and discard the skins.
- Simmer with stock and bay leaf. Transfer the prepared vegetables to a large pot. Add the vegetable stock and bay leaf. Bring to a simmer over medium heat and cook gently for 10-15 minutes to meld the flavors.
- Remove bay leaf and blend smooth. Discard the bay leaf. Stir in the sour cream, then use an immersion blender (or carefully transfer to a blender in batches) to puree the soup until completely smooth. Taste and adjust seasoning as desired before serving warm.
Notes
- For a vegan version, substitute sour cream with a plant-based alternative.
- Roasting the vegetables enhances their sweetness and depth of flavor.
- If you prefer a thinner soup, add more vegetable stock to reach desired consistency.
- Leftovers will keep in the refrigerator for up to 4 days or can be frozen for up to 2 months.
